The daily tasks such as production Oracle DBA & developer DBA

Hi all DBA,.

I'm curious to know what you do every day as production Oracle DBA or developer DBA. More than a year ago, I became a DBA and before that, I was PL/SQL Developer. I navigate in the Administrator's guide and, now, in the middle of the Oracle database concepts. Then I intend to read backup and restore. As my day job: I check the backup log file. Check db objects and make sure that all are valid and check free space on each tablespace and adding data files if necessary. Also monitor top sqls session or above through OEM and tried tune sqls top of the page. Meet the demands of users, such 'kill a suspended session' and synchronize the data of a table between databases and refresh QA production db app. sometimes the air in the alerts log too if we have problems. Some people suggested TKPROF each file in short why trace the trace file generated. Don't you think that it is really beneficial? What should I do to improve the skills and abilities as an Oracle DBA. Really appreciate your ideas.

Shirley

  • Need help to unlock the user account HR in the example (rich Web Applications with Oracle ADF development)

    I am very new to Java development and have tried to launch the sample application (Development of Web Applications with Oracle ADF rich) in the start-up, the author of this app has advised developers to unlock the HR user account.

    What I did to connect to Oracle as user = system/password = system and running this SQL command 'ALTER USER HR IDENTIFIED BY NewPwd ACCOUNT UNLOCK"in Sqlplus and with a return code 2.

    Don't code 2: success or failure?

    However, the HR user is always unlocked after issuing this command, and can someone please tell me what I'm doing wrong?

    Thank you.

    Timo,

    Thanks for confirming. The essential difference is that the command must be run as

    SYS AS SYSDBA

    instead of such as SYSTEM

  • Partitions don't synchronize only not - Oracle SQL Developer 4.1.3.20

    Hello

    First of all, thanks a lot for developers for this great tool.

    I use the Data Modeler which comes with Oracle SQL Developer 4.1.3.20.

    In the 12 c database, I created the following table:

    CREATE

    TABLE MMOURA. TEST_TABLE

    (

    NUMBER OF ID_TEST_TABLE (10) NOT NULL

    DATE_TEST_TABLE DATE NOT NULL

    )

    ORGANIZATION HEAP PCTFREE 10

    LOGGING NOCOMPRESS NO INMEMORY

    NOCACHE NOPARALLEL NOROWDEPENDENCIES DISABLE THE MOVEMENT OF THE LINE;

    I import with Data Modeler and add the partition:

    CREATE

    TABLE MMOURA. TEST_TABLE

    (

    NUMBER OF ID_TEST_TABLE (10) NOT NULL

    DATE_TEST_TABLE DATE NOT NULL

    )

    ORGANIZATION HEAP PCTFREE 10 TABLESPACE SYSTEM NOT LOGGING NOCOMPRESS NO INMEMORY RANGE PARTITION

    (

    DATE_TEST_TABLE

    )

    INTERVAL OF

    (

    NUMTOYMINTERVAL (1, 'MONTH')

    )

    (

    PARTITION P_BEFORE_2010 VALUES LESS THAN (TO_DATE (JANUARY 1, 2010 ',' DD/MM/YYYY "")) NOCOMPRESS

    )

    NOCACHE NOPARALLEL NOROWDEPENDENCIES DISABLE THE MOVEMENT OF THE LINE;

    So I can create a partition and generates the correct code.

    I click on "Synchronize data dictionary with model" and see the differences with the model and the database.

    In the models 'compare', 'Physical Details' is red. 'Partition' is red, "Selected" are marked, "Source table: TEST_TABLE ' is YES and" target Table: TEST_TABLE "is no.

    "Partitioning" is marked, and I can see the new partition "P_BEFORE_2010."

    teste_partition_chamado_oracle.png

    But when I click on 'Overview of DOF', theres no changes:

    -Generated by Oracle SQL Developer Data Modeler 4.1.3.901

    What I am doing wrong? Is this some sort of bug?

  • Oracle SQL Developer/Oracle 11 g/Windows 7 - cannot connect 'sys as sysdba'

    Hello

    I downloaded and installed SQL Developer 3.2.20.09, the latest version, separately from Oracle 11 g, because the version provided with Oracle 11 g did not work properly.

    Now, I'm trying to connect SQL Developer 3.2 to my instance of 11g Oracle installed on Windows 7.

    I can log in with the user name SYS AS SYSDBA using SQLPLUS, text bundled with Oracle 11g, with a password to null and without any problem.

    However, when I try to connect to the same instance using the graphical tool based on Java, Oracle SQL Developer 3.2 I get this error:

    Status: Failure-Test failed: ORA-01031: insufficient privileges

    I already checked the computer management and I am already a member of administrators and 'ORA_DBA' groups.
    I already checked tnsnames.ora, etc. and everything is indicated as it should.
    I also checked my SID and it corresponds to what was named during the installation of Oracle 11 g.

    Is someone can you please tell me why I can't connect using SYS AS SYSDBA?

  • What are the best free tools for Oracle DBA development?

    Hi, I have been for years production dba. I am familiar with a complete cycle of the installation of the database, configure, backup recovery, etc.

    Now my role will change soon for development dba. I have no problem to create instances. Then in the data modeling, data standardization, etc., what kind of tools I can use?

    Good suggestions, or documents that you can provide?

    Thanks in advance.

    Oracle SQL Developer Data Modeler and Oracle JDeveloper can be used for data modeling. Both of these tools are free. You can try and make your idea - they are free.
    We will be happy to receive your comments on Data Modeler.

  • AGAIN starts after only one physical disk has several partitions makes no sense to the production oracle database?

    Dear Experts,

    Don't + REDO1 diskgroup have only one physical disk has several partitions makes no sense to the production oracle database?

    For example

    • + Diskgroup Redo1 have 2 50 GB disks (fact these 2 discs are the same physical disk partitions OR these should be separate disk as recommended approach)?
    • + Diskgroup Redo1 have 2 drives of capacity 50 GB (for RAID 1 + 0)
    • + Diskgroup Redo2 have 2 50 GB disks
    • + Diskgroup Redo2 have 2 drives of capacity 50 GB (for RAID 1 + 0 )

    Thank you and best regards,

    Hello

    Partitioning your disks for ASM configuration as 'A' might make sense. If you lose one disk, you have the discs to another.

    'B' totally make sense if you have lost the disc that you have lost all group ASM and you need to change this with something like 'C '.

    But obviously you need redundancy ASM configured appropriately.

    Kind regards

    Segregation starts may travel on these factors

    • 1. the speed of the disks (redologs online had to be faster disk)
    • 2. the redo of multiplexing files
    • 3. the multiplex control files
    • 4. after archivelogs on another disk
    • 5. other than the DATA + and + FRA

    Yes, but 2-4 points can be met with groups of two discs as well - + data the primary file hosting and + FRA accommodation multiplexes copies.

  • All files generated by a coil in sqlplus receive ownership of oracle: dba instead of the user of the BONE started sqlplus and run the script. There's a file with users owners of BONES of the coil.

    All files generated by a coil in sqlplus receive ownership of oracle: dba instead of the user of the BONE started sqlplus and run the script. There's a file with users owners of BONES of the coil.

    Script launched in until OS user 'A' on the 'A' server which launches sqlplus, then connects to a remote database through a service of tnsnames.ora as another user of the database and the results of this script are spoulées on the server "A".

    The file queued on the old server is written with rw-rw-r: read write user, group read the writing, reading and possession header that is the user of the OS. The file queued on the new server is written to rw-r-r user: reading writing, reading group, public reading and ownership oracle: dba.

    "" The user then has no privileges to modify the file and continue the process of transmitting the file, editing and deleting the file for the next set of commands. This allows us to keep the possibility to migrate to the new server we are unable to process orders.

    $ORACLE_HOME/bin/sqlplus - s user/password@prd1 @./script/CustomScript/R12_OM_UFPC-oracle.sql

    Background: old server running 4.8, Oracle 10.2.0.4 OEL

    New server running OEL 6.5, Oracle 11.2.0.4

    Tested so far:

    File and update umask to 0002 instead of 0022 is now generated as rw-r-r. However, the property is still oracle: dba.

    Update of ownershipt of $ORACLE_HOME/bin/oracle.exe of oracle: oracle (edi added the user to the oracle group) and chmod 6751 oracle.exe. This created several problems where crucial scripts, that is to say of sqlplus failed to run.

    Added! chmod 755 output.file.name - OS user 'A' is not allowed to change to mod.

    Added! command cp MV output file and that generated the file as a user of the operating system: oracle. It is a potential work around in case of emergency, but the developer would have to rewrite the countless scripts.

    Any ideas?

    I have reproduced the behavior of the old server and am able to spool a file via sqlplus under OS user. No changes have been made on the remote database server. All the changes have been on the new server hosting a small 11.2.0.4 database on a server running OEL 6.5 32 - bit OS.

    (1) removed the sticky bit $ORACLE_HOME/bin/sqlplus using chmod u-s, g-s, o - s suggestion of Billy ~ Verreynne

    (2) modified the main group for the 'oracle' user match the user operating system applications, while maintaining membership in the groups 'oracle' and 'dba '.

    -We are dealing with here EDI processes, so the Group was called edi.

    (3) modified property of the files tnsnames.ora and listener.ora for oracle: edi

    (4) restart the receiver

    (5) disconnect / reconnect

    Script runs as expected, the output file contains the correct ownership and permissions.

    Thank you all for taking a look and offering options.
