Black Men Erections Images

Think

reading Tom Kyte's book "Expert Oracle Database Architecture, Second Edition," was excellent the preface written by Ken Jacobs in which he writes about how a word used in 1914 by Thomas J. Watson to convey an idea IBM workers, regardless of their position, taking care in making decisions in addition to working with intelligence. Jacobs

emphasis on "conventional experience that exists in the Oracle community about how to optimize for best performance or the best way to use various features of Oracle. This experience that sometimes it becomes folklore or myth and that both developers and database administrators applied blindly or beyond without any reasoning.

An example of this is the idea of \u200b\u200b"if one is good, more-many more are better." The idea is popular, but not always true. The Oracle interface arrangement, for example, that allows developers to insert or remove multiple records with one call thus reducing the number of network messages between the application and the database which is good. But if you analyze it, there is a point where performance decreases. It is much better transport 100 records while 1.000 and for the latter case the method is not efficient, especially for memory requirements.

Another example is when it focuses on wrong aspects of the design or system configuration, rather than those which can improve performance (or, if applicable, reliability, availability or security). Consider the conventional experience of optimizing the system to maximize the 'buffer hit ratio. " For some applications, it is true that maximize the chance that the system finds the data in memory will improve performance. However, in most systems it is best to focus on bottlenecks (which in the argot of Oracle is known as "wait states") rather than focusing on specific indicators. Attack from the design ensures that the system has good performance.

Sometimes good practices that were based, in part, to a degree of certainty no longer apply when the facts change. Consider the old adage, "to indexes and data in different tablespaces for performance." There are database administrators who defend tooth and nail this idea without taking into account changes in disk speed and capacity, or related to workloads. In assessing this "rule" should think about the fact that load into memory Oracle database blocks used recently and frequently (often blocks belonging to an index), and the fact of which makes use of these blocks sequentially, not simultaneously, for any request. This implies that the operations of I / O for both indices to data should be shared among all concurrent users and distributed over all disks to be available. You can choose to separate indices and data for administrative reasons or personal preference, but not for performance. The important thing is to base decisions on facts, many facts.

No matter how fast our computers are so sophisticated or who may become the database, regardless of the power of our programming tools, there is simply no substitute for human intelligence accompanied by a "thinking discipline." While it is important to learn the intricacies of the technologies we use in our applications, it is even more important to know how to think them appropriate use.

Tom's book not only teaches about Oracle features and how to use, it also reflects many of these simple thoughts:
  • not believe in myths. Explain yourself.
  • not go with the conventional experience. Often the things that everybody knows are just wrong! Distrust
  • rumors or opinions. Try things yourself and your decisions based on facts examples.
  • Divide the problem in simple questions and answers weapon at every step in an elegant and efficient solution.
  • No execute things in your program when the database can do better and faster.
  • Research on the topic and is skeptical of unjustified policies in the company for technical standards.
  • Take time to THINK.

addition to this, I would add also the advice of Steven Feuerstein I posted a few posts ago. While it is always ideal to have the time and equipment to do all the tests that need the reality is that rarely have, often perhaps for the lack of time many are left with the idea that what saw that others also work for them worked and may well be, however, with so many combinations in Oracle as database, operating systems and hardware, it could build on this knowledge but the test is one that will actually solve the problem. Once

you how to solve the problem is important to see also the implications for others because instead of solving it could be just a different location.

How Long Is Lorazepam Detectable In Blood

ORA-01220: file based sort illegal database is open

few days ago I found working with RMAN with the message described in the title. It was still pre-production base and less than 50 GB in size with a little over 30 datafiles. Activity in that time was to restore the more than 30 datafiles with the control files, that is, to simulate the worst case scenario where "all" the database files are lost. With all quotes I am referring only to files that can be restored from RMAN, because the database includes other files that are not considered critical to jump-start a backup.

The full message is: RMAN-00571
: ===================================== ======================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ==== ===========
RMAN-00571: =============================================
============== RMAN-03002: failure of restore command at 11/08/2010 16:36:39
ORA-01220: file based sort illegal database is open
Before
After deleting the control files with more than 30 filesystem datafiles, the command to restore from RMAN simply threw the previous message.

According to Oracle documentation, the message ORA-01220 concerns that tried to run a query, but the buffer (memory) for systems not large enough to carry it out. It deals specifically with the parameters and SORT_AREA_SIZE SORT_AREA_RETAINED_SIZE . TYPE NAME

; VALUE ------------------------- -------- -------

nls_sort string Sort_area_retained_size

SORT_AREA_SIZE integer integer 0 65536

by default in 10g, the SORT_AREA_SIZE parameter has a value of 64K and SORT_AREA_RETAINED_SIZE parameter is 0 because RMAN requires management to make a buffer size but not enough to do, go to the second resource is TEMP (temporary tablespace) However, as this database far only been found in MOUNT can not use the TEMP, hence the only recourse is to increase the value of these two parameters.

SQL> alter system set SORT_AREA_SIZE = 10485760 scope = spfile;

System altered.

SQL> alter system set sort_area_retained_size = 10485760 scope = spfile;

System altered.

SQL> shutdown Immediate;
ORA-01109: database not open Database

dismount.
ORACLE instance shut down.

SQL> startup mount;
ORACLE instance started.

Database mounted.

SQL> show parameter sort

------------------------- -------- -------
nls_sort                  string Sort_area_retained_size

SORT_AREA_SIZE integer integer 10485760 10485760

10 Mb should be sufficient to launch the restore without problems. Once recovered and found to support the instance opens without problems is necessary to return the settings to their original values. As a dba does not take long to realize what it is and its possible solution, as implementer of solutions without knowledgeable support RMAN or Oracle, such as HP Data Protector or EMC Avamar creating custom scripts to launch them from the Recovery Manager could be a headache because they have no access to modify parameters, which in fact they should not only permission - or worse still take hours or days to find what it is about the problem and implement the possible solution.

Testing svn client on Linux

Hello everyone, well as you have noticed for thousands of years since anyone has written anything, but hey it's never too late say around and then I recently saw the need to use any svn client for linux and the first thing that came to mind was NautilusSVN that I have comfortably installed in ubuntu, but good at the time of installation for Debian began to beat me so I started to lose no time to check some other clients and I found these two that perhaps not the best in the world but they are certainly decent: rapidsvn and kdesvn (this I liked the most: D) \u200b\u200beasy to install and simple to use. Well I say goodbye and if they misbehave not warn me that probably will not haha: D.

Sample Letters For Church Anniversary

Before And you, what applications you use Open Source?

All applications installed on our computers have a discharge, starting with the operating system. Licenses range from those that only have to pay to receive a copy of the executable to those that are free (not to be confused with free) and give you access to the code source.

The big difference between the software "free" and "open source" is that the former is implicit in the second but the second you get to see how the application inside, that is, its source code. As an end user the most important thing is to maximize ease of use that gives you an application, the developer is interesting to see how they are applied various programming techniques, from how to write code to the use of computational paradigms both simple and advanced .

Open Source applications for everyday use can not miss on my machine:
  • Firefox - No description. Thunderbird
  • - Excellent mail client.
  • Workrave - Helps you to take breaks from computer use. Great for those who spend long periods of time in front of one.
  • Notepad + + - Excellent text editor with many useful options. WinSCP
  • - Better and more complete client Filezilla file transfer (for my taste of course). PDFCreator
  • - Excellent application to create PDF files via a virtual printer with many other options for output formats, not just PDF. Highly recommended for those occasions when you need save web pages.
  • Cygwin - Linux Command Emulator for Windows. Recommended for administrators who do not fear the command line. Privoxy
  • - Tired of seeing websites where what stands out (and clogging osaciones) is advertising? With this application you'll forget all that crap visual. GIMP
  • - Excellent application for manipulating images.
  • MKVToolnix - Excellent tool to manipulate Matroska file types.
  • Jubler - Very good application for editing subtitle files (SRT) although it could be even better.
  • SharpDevelop - very good IDE for programming in C #, among other programming languages. NET platform
  • Media Player Classic - Home Cinema - Media player with support for various multimedia formats.

Does Anyone Get White Creamy Cm 1 Week Before Af

encrypted data transport ASO Getting

By default, communication between the database and a remote client is accomplished without any encryption method, ie all instructions executed and the data can be intercepted by someone listening on the network using a 'sniffer'. In businesses which handle confidential information leakage risk is very high so someone with skills in pattern recognition could easily be made of this information.

Oracle has a feature called "Oracle Advanced Security 'which is necessary to configure both the server and client. This configuration is done in the sqlnet.ora file so no need to alter the applications or restart the instance. Remote connections made after the settings are already using the method of encryption that is defined but not existing connections.

In the scheme I have SCOTT CUSTOMER table with the following definition and data:
SQL> select name, credit_card from scott.customer;
CREDIT_CARD

-------- -------------------- NAME pedro sergio

1234-1234-1234-1234 1234-1234-1234-1235 1234-1234-1234-1236

juan Using IP Tools tool as 'sniffer' and applying the above query we get the following.

Definition:

and outcome:


addition to many other characters both familiar and strange, we see that it fails to distinguish at a glance the names 'sergio', 'pedro', 'john' accompanied by their credit card numbers . In a production environment this course is not acceptable.

This is where security comes into play through encryption.

Using the tool "Oracle Net Manager 'expand node' Local 'and select' Profile '. In the upper right pane open the 'combo box' and select 'Oracle Advanced Security. "


If 'Oracle Advanced Security "appears not deployed, you must do the following. Edit the NetProperties directory $ ORACLE_HOME / network / tools , adding "ASO " at the end of the line that begins with " INSTALLEDCOMPONENTS ."
INSTALLEDCOMPONENTS = CLIENT, ORACLENET, ANO, ASO Closes

'Oracle Net Manager "and run again, the' Oracle Advanced Security" and should appear.

Select the tab 'Integrity' in the item 'Integrity' select "SERVER" in "Checksum Level" select "requested" and the list 'Available Methods' select "MD5" and press the button '>'


Then select the tab 'Encryption' in the item 'Encryption' select "SERVER" in "Encryption Type" select "requested" in 'Encryption Seed' write a string long enough to serve for the encryption and the list 'Available Methods' select' 3DES168 "and press the button '>'


The settings in each a customer is basically the same, just change the value of the items 'Integrity' and 'Encryption' of "SERVER" to "CLIENT" and specify in 'Encryption Seed' a completely different string to the server.



not forget to save the settings made in "Oracle Net Manager" (File -> Save Network Configuration), then when we forget to wonder why it does not work and even comes to seeking a solution beyond the problem, usually happens:).

Finally, to prove that everything is working correctly is to close the SQL * Plus, opening a new one, enable the 'sniffer' and run the query on the table scott.customer again.

We now see that only shows a set of meaningless characters and can not see the definition:

nor can already see the data:


All encryption methods shown in ' Oracle Net Manager "are industry standards, which will depend almost the level of encryption that is required to elect any of them.

"Changes in applications? None. Suspension of service "database? None. Extent of reliability? Complete.

Note: Like most "extra parts" that come with database, this functionality may have an extra license cost for what I would recommend check before deploying in a production environment.

How Long Does Mayonnaise Packets Stay Good

DDLs with Oracle export / import and Pretoria

A quick and elegant way to extract DDL instructions of the database is to create a dmp file with only the structures, extract the SQL statements to import (indexfile option) and format with Pretoria .

Pretoria is a tool that analyzes the structure of import-file created specifically to indexfile option. You can search and replace the storage parameters of tables, indexes and clusters, as well to separate the instructions for creating tables and indexes on their own. These files can be pre-create all segments of the database, basically to reorganize. If you have a database with hundreds of tables, do a manual reorganization in the DDL time consuming. Pretoria employ only takes a few minutes.

Creating dmp file

Oracle export tool basically does is remove the definition of the segments database (tables, indexes) and the data they contain. For this exercise I will use the SCOTT schema created by Oracle as part of such schemes for a 10gR2 database mounted on Linux RHEL 4.

If SCOTT is locked, you will have to unlock it and assign a password.
SQL> alter user scott account unlock;

User altered.

SQL> alter user scott IDENTIFIED BY tiger;

User altered.

export is executed without segments bd.
[oracle @ testserver ~] $ exp scott / tiger @ orcl file = ~ / sch_scott.dmp owner = scott rows = n grants = n statistics = none

The resulting file 'sch_scott.idx' contains the DDL of tables, constraints and indexes. The first two appear as comments (with REM at the beginning of the line), the only legible at first glance are the CREATE INDEX. This is where the tool comes in Pretoria. The implementation of import with the option indexfile not actually execute any DDL or import data (in case of using a full dmp file) all it does is remove the DDLs and stored in the file specified in the option indexfile.

Segregated

DDL

Pretoria is actually a set of Java classes converted to the platform language to avoid the drawbacks that represents the encoding of shell scripts in different types of * nix tool particularly AWK. In the documentation section brings a graphic scheme that developers used to make it efficient.

If our interest is to extract the DDL statements as they are, just run the following statement:
[oracle @ testserver ~] $ java sch_scott.idx Pretoria-i-ot-oi scott_tables.ddl scott_indexes.ddl - nc
input Spawn thread! Spawn process
threads! Spawn threads
output!
Input thread done!
All done!

With this, the file sch_scott.idx barely legible on the face is processed and divided into two files, one with the definition of the tables and the other with the definition of indexes and constraints. Sample code

without applying Pretoria:
REM CREATE TABLE "SCOTT". "BONUS" ("ENAME" VARCHAR2 (10), "JOB"
REM VARCHAR2 (9), "SAL" NUMBER, "COMM" NUMBER) PCTUSED PCTFREE 10 INITRANS 1 40
MAXTRANS 255 REM STORAGE (INITIAL 65536 FREELISTS 1 freelist
BUFFER_POOL DEFAULT REM GROUPS 1) TABLESPACE "USERS" LOGGING nocompress;
REM CREATE TABLE "SCOTT". "DEPT" ("DEPTNO" NUMBER (2, 0), "DNAME"
REM VARCHAR2 (14), "LOC" VARCHAR2 (13)) PCTFREE 40 INITRANS 1 10 PCTUSED MAXTRANS
255 REM STORAGE (INITIAL 65536 FREELISTS 1 freelist REM GROUPS 1
BUFFER_POOL DEFAULT) TABLESPACE "USERS" LOGGING nocompress;

Example Pretoria applying code:
CREATE TABLE "SCOTT". "BONUS"
("ENAME" VARCHAR2 (10),
"JOB" VARCHAR2 (9),
"SAL" NUMBER,
"COMM" NUMBER) PCTFREE 10 PCTUSED
40 INITRANS 1 STORAGE
MAXTRANS
255 (INITIAL 65536
FREELISTS 1
  FREELIST GROUPS 1
  BUFFER_POOL DEFAULT ) TABLESPACE "USERS" LOGGING NOCOMPRESS ;

CREATE TABLE "SCOTT"."DEPT"
  ( "DEPTNO" NUMBER ( 2 ,0 ) ,
  "DNAME" VARCHAR2 ( 14 ) ,
  "LOC" VARCHAR2 ( 13 ) )
PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255
STORAGE
  ( INITIAL 65536
  FREELISTS 1
  FREELIST GROUPS 1
  BUFFER_POOL DEFAULT ) TABLESPACE "USERS" LOGGING NOCOMPRESS ;

Example specifying parameter file.
[oracle @ testserver ~] $ java-s storage Pretoria sch_scott.idx-ot-i-oi scott_tables.ddl
Hashing scott_indexes.ddl-nc storage parameters ...
Done! Spawn
input thread! Spawn process
threads! Spawn threads
output! Input thread
done!
All done!

The file should contain the parameters that need updating in the script output. For the example above I specified only to update the tablespace for tables and DEPT BONUS:
"SCOTT". "BONUS" TABLESPACE TS1
"SCOTT". "DEPT" TABLESPACE TS2

As the result: CREATE
TABLE "SCOTT"."BONUS"
  ( "ENAME" VARCHAR2 ( 10 ) ,
  "JOB" VARCHAR2 ( 9 ) ,
  "SAL" NUMBER ,
  "COMM" NUMBER )
PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255
STORAGE
  ( INITIAL 65536
  FREELISTS 1
  FREELIST GROUPS 1
  BUFFER_POOL DEFAULT ) TABLESPACE TS1 LOGGING NOCOMPRESS ;

CREATE TABLE "SCOTT"."DEPT"
  ( "DEPTNO" NUMBER ( 2 ,0 ) ,
"DNAME" VARCHAR2 (14),
"LOC" VARCHAR2 (13)) PCTFREE 10 PCTUSED
40 INITRANS 1 STORAGE
MAXTRANS
255 (INITIAL 65536
; FREELISTS 1
freelist BUFFER_POOL
DEFAULT GROUPS 1) LOGGING TABLESPACE TS2 nocompress;

Changing the USERS tablespace for the table in TS1 and TS2 BONUS for DEPT.

still better, if you're going to reorganize the database tables by moving the tablespace can do it with the following line in the parameter file:
default_t ("SCOTT") TABLESPACE TS_DATA

Making all tables in the SCOTT schema are assigned the default tablespace TS_DATA, quite useful if it is hundreds of tables. You can even specify the tablespace in particular tables, for example:
default_t ("SCOTT") TABLESPACE TS_DATA
"SCOTT". "BONUS" TABLESPACE TS1

is, by default assigned to the tables in the SCOTT schema tablespace except TS_DATA BONUS to the table to which you are going to assign TS1.

addition tablespace parameters you can specify the file to update the script with these values \u200b\u200bare:
  • PCTUSED
  • PCTFREE
  • INITIAL NEXT
  • MINEXTENTS
  • MAXEXTENTS
  • PCTINCREASE
  • FREELISTS
  • freelist GROUPS
  • INITRANS
  • MAXTRANS
  • DEGREE

The other options including Pretoria may be running:

No space in the Flash Recovery Area (FRA)

Recovery Manager complete.



see that it's actually three messages. The first (RMAN-03002) indicates that RMAN failed to support implementation including archivelogs. The second (ORA-19809) that there is more space to store backups and finally (ORA-19804) that failed to release about 52 Mb of space in the FRA. Reviewing directory size designed to FRA operating system level, we see that:
[oracle @ testserver oracle] $ du-sk flash_recovery_area
1835880 flash_recovery_area

has occupied little more than 1.8 Gb and revising the settings at Oracle:

SQL> show parameter NAME db_recovery_file_dest_size

; TYPE VALUE
------------------------------------ ----------- - ----------------------------
db_recovery_file_dest_size ; big integer 2G

FRA size is 2 GB

workaround, Oracle intends to implement any of the following 5 options: Support the FRA

using RMAN.

Change RMAN retention policy. Change the policy
  1. deletion of archive logs.
  2. Add disk space and increase the value of the parameter DB_RECOVERY_FILE_DEST_SIZE.
  3. Delete Files RMAN using FRA.
  4. The FRA can be configured to occupy only a portion of the disk-February 2 GB by default, so in this case the most convenient option is to increase its size.
  5. SQL> alter system set db_recovery_file_dest_size = 3G scope = both;
System altered.
done this, just throw back your backup.

no obsolete backups found

Recovery Manager complete. Reviewing

execution log, we see that this time did not return any error messages. And we see the difference of space occupied in the FRA that went from 1.8 Gb to just over 2.6, ie, it took just over 800 MB of free space in the FRA for the backup could run without problems.

[oracle @ testserver oracle] $ du-sk flash_recovery_area
2635256 flash_recovery_area

If space for the FRA was set equal to the size of the disk or filesystem and had no extra space, would then have to use some of the other 4 options involving getting rid of files to free space in the FRA. Before deleting any files managed by RMAN sure there is a backing away from the FRA, for example tape or other storage medium, with this ensures that in an eventuality in the production database, you will have the means to restore .

Rubbery Discharge During Pregnancy

Scientists break the terabyte barrier system of

Computer Science at the University of California, San Diego (USA) broke "the terabyte barrier"-and a world record by ordering more than one terabyte of information (1.000 gigabytes or 1 million megabytes ) in just 60 seconds. In competition Sort Benchmark
-the "World Cup of ordering data" - computer scientists at the Jacobs School of Engineering at UC San Diego also tied the world record for the fastest rate system. Ordered a zillion records in 172 minutes and did it with only a quarter of the computational resources of the previous record. Companies

for trends, efficiency and other competitive advantages have turned to this kind of arrangement which requires heavy hardware processing power of typical data centers. The Internet has also created several scenarios where the information system is critical. Advertising on Facebook pages, personal recommendations from Amazon, and search results as Google-second of all are the result of huge data sets to order multiples of petabytes. A petabyte is 1,000 terabytes.


"If a big corporation would run a query across all visitors to their sites or products sold, may need to order a set of multi-petabyte data and especially those that grow to several gigabytes per day," computer says Professor UC San Diego Amin Vahdat, project leader. "Companies are taking to limit the amount of information that can be ordered, and how fast. This is analysis of information in real time, "said Vahdat. We need better management technologies, however. " In data centers, the system is the most common bottleneck in many high-level activities, "said Vahdat who directs the Center for Network Systems (CNS) at UC San Diego.
The two new world records for the UC San Diego are among the recently disclosed results sortbenchmark.org - site run by computer scientists from academia and business volunteers who run the competitions. These powers provide marks in terms of data systems and a forum Interactive researchers working to improve management techniques. World Records



This is the first year that scientists enter the competition and win in the Indy Land in a Minute and Order Indy Gris.

In the first, the researchers instructed 1.014 terabytes in a minute - breaking the minute barrier for the first time.

"We set our agenda for research on how to improve it ... also make it more generic," says doctoral student in computer science at UC San Diego Alex Rasmussen, leader of the team graduate students.

team also tied the world record in the "Land Indy Grey" which measures the rate per minute system 100 terabytes of information.

"We use computers a quarter of the previous team record was used to achieve the same rate law - which meant using only a quarter of electricity, cooling and physical space," says George Porter, a research scientist in CNS of the UC San Diego.

Two world records fall under the category "Indy" - which means that the systems were designed around specific parameters for competition. The team aims to generalize their results to the competition, "Daytona" and that can be used in real environments.

"The system is also an interesting way to various information processing problems. In general, it is a good way to measure how fast can you read a lot of data from a disk set, apply some processing, distributed by a network and write another set of disks, "said Rasmussen. "Sort puts too much pressure on the subsystem input / output, from hard disks and network cards to the operating system and applications." Balanced Systems



The challenge of sorting data that scientists are taking very different from the modest systems that systems Conventional databases can be done by comparing two tables. The biggest difference is that the laws of terabytes and petabytes of data beyond the memory capacity of the server that makes it.

establishing the system of heavy-duty system, scientists are designed to roll and quickly. A balanced system is one in which resources such as memory, storage and network bandwidth, are fully exploited and only a few resources are wasted.

"Our system shows what is possible if one pays attention to efficiency - and there is still much to improve," Vahdat says "We ask the question What does build a balanced system in no system resources are being missed having a high performance computing? If you have unused or idle processors all the RAM, you're wasting energy and losing efficiency. "Memory often uses the same energy as a processor or more including, for example, but nobody notices that.

Breaking terabyte barrier under the national Indy in a minute, the researchers built a system made of 52 computer nodes. Each node is a standard server with two quad-core processors, 24 gigabytes of memory and 16 drives all interconnected by a Cisco switch Nexus 5020. Cisco switches donated as part of the research sought they have with the Center for Network Systems at UC San Diego. The computer cluster is hosted at the Institute for Telecommunications and Information Technology California (Calit2).

To win the Indy Land Gray, investigators ordered a zillion records in 10,318 seconds (approximately 172 minutes), leaving his world record tied with a ranking of 0,582 terabytes per minute per 100 terabytes of data. The winning system is made of 47 nodes similar to those used in the order of a minute.

100 terabytes of information equal to 4,000 Blu-Ray of a layer, a layer DVDs 21.000, 12.000 dual-layer DVDs or CDs 142.248 (assuming are CDs of 703 MB).

Microfiber Vs. Microsuade

And you what that DBA are you? Avoiding

book "Oracle 11g Database Administrator for Advice Underground's - Beyond the basics - real-world DBA A survival guide for Oracle 11g database Implementations" written by April Sims and published by Packt Publishing who lists the following activities rightly DBA should be met, taking into account of course the work environment as they do not all apply to all cases. For example, a person who was hired to be in charge of say 20 databases with which the company operates, has many more responsibilities that a consultant as-first-a consultant will charge to the extent of consumption of hours care and generally the cost of this service is not cheap. Of course, depending on the contract, the consultant may from diagnostics in this or that problem that the present database, to implement solutions to correct notable performance problems or implementing new functionality all in favor of organizational software process improvement. You could say that both have similar profiles but with different specializations.
What does a DBA do all day? The responsibilities are , install, configure and administer the database, these responsibilities can be divided into scheduled tasks to run at certain intervals. This is a generalized list and depending on the workplace may or may not apply.


Tasks such as monitoring and log rotation can be done via Enterprise Manager, Grid Control, Unix shell scripts, DBMS_SCHEDULER, Perl, database tools, third-or combinations of some of these. Prioritizing activities, daily, weekly, monthly, quarterly or annual
Let's see what are the priority activities needed to cover. The schedule depends on the workplace needs of the application and having the weight activities in general.



Daily Backups - are usually incremental and cumulative, one full week and the logs are stored and mailed to the DBA in case of failure.
Alert Log database - such as ORA errors, automatic email notifications, messages to pagers.
  • ADRCI - Automatic and Log Rotation Utility Repository.
  • filesystem space, CPU statistics and I / O - Manager requires OS support.
  • SQL statements - Statements that are among the top 5 and 10.
  • Corruption - RMAN logs, logs of exports and / or DataPump, dbverify, v $ database_block_corruption
  • .
  • tablespaces Growth - grow them, partition management, temporary tablespaces, undo. Data Guard - check in the logs that the application / transport is in sync. Logs
  • SQL * NET listener - intrusion detection.
  • Audit logs and evidence - intrusion detection, removing unused accounts.
  • Dumps core and user - space they occupy, Oracle bugs.
  • Creating new accounts - should be at least partly automated.
  • Update users about security - at least 24 hours in advance. Migrating
  • diagrams and code changes or updates specific to SQL.
  • Growth of large tables, uniform growth of tablespace.
  • Keeping track of daily changes to the database - for some people post of IT staff.


Weekly Backups - usually the entire database.
database cloning for non-productive - or automated scripts. Growth
  • tablespaces - the daily accumulated in a week.
  • Improved version of Oracle or migration projects for patching - Updates significant.
  • Test Data Guard site. Review
  • updates My Oracle Support (MOS) - new patches, updates or new versions.
  • Updates on local intranet on operational procedures.
  • Monthly


database cloning for non-productive - or automated scripts.
growth monitoring tablespaces - the weekly accumulated in a month.
  • Trends and Forecasts - CPU consumption, statistics I / O, access
  • Change passwords in production - sys, system, wallet, schema, control grid, OAS. Licenses
  • use Oracle and it covers. Implement
  • recovery scenarios.
  • Quarterly


Application CPUs (Critical Patch Upate) and PSUs (September Patch Updates) production planning in suspension of service. Application of CPUs, PSUs instances once unproductive.
growth monitoring tablespaces - the monthly accumulated in an annual update courses
  • Oracle - Oracle University (online or classroom), books, informal meetings. Accumulation
  • trends and forecasts.


Annual Growth tablespaces - annual report.
Sum of trends and forecasts.
  • Oracle Go to conferences - groups of local or national users.
  • Oracle Updates planned service suspended - version + patches + PSUs + application once.
  • Software Licensing and renewal services.
  • Evaluation and updating of hardware.
  • SSL Certificate Renewal, Oracle Wallets.
  • So, it looks like a bleak set of activities carried out, however, it has the support of tools such as OEM, Grid Control, third party monitoring or custom-made scripts. That is why it is the reiteration that the automation of these tasks is of great importance.

If generalize several of the points mentioned above, we will apply not only to the Oracle platform but can also serve as a reference for managers manage other databases.

Pokemon Black And White Birthday Invitations

mess up (seriously) and Oracle DBA

-Underground Advice for Database Administrators. Beyond the basics. A real-world survival guide for Oracle DBA 11g database Implementations" publisher Packt Publishing written by April C. Sims, makes an excellent summary of situations or activities that Oracle DBA happen if they could make us a hard day or our boss or the boss's boss. Be cautious, focusing on what is done and in some cases to double-check what you are going to run and on which server is only part of the performance to make your job more if it bears the title "DBA" . Seriously, some people have the wrong idea about what a DBA, but that's a topic for another entry.
These are the points A. Sims is well to mention.


Avoid using rm-rf *.*
at any time and for whatever reason, try to be specific
  • rm *. log or *. lis or *. trc: it is more likely to support the board and make better use rmdir . It would be even better if you rename the whole directory and then you let one or two days. assume that all files in a directory that you see belong to a single database is an omen of disaster, these files can be created anywhere in the filesystem to which Oracle has write access. Modify access to productive instance at SQL * Plus is not a rule and usually not given directly to the developers unless a person take over that responsibility as the head development.
  • is good to use Unix tool
  • fuser against a file to determine whether or not to be used before executing commands
  • rm or mv . Another way is to force a checkpoint and check the timestamp before disposal. If the file is active, the timestamp is updated. Add ORACLE_SID and prompt the user to SQL. This will prevent disaster to visually inspect the prompt before running a script as you think it's a production server. Use a extended at Unix prompt that contains the hostname, username and ORACLE_SID which will add more tracks visual you make sure you know exactly what you want to modify.
