Production database administration
What is the difference between development DBA and production DBA? Will the junior/mid level DBAs be involved in production database administration?
You can't say DEV DBA or production DBA. The word should be development environment and production environment.
Development environment- This environment is used for testing purpose for the company. In this environment developer can change/alter/deploy their code as necessary. They can change any object for the business requirements and test. If the test is successful they can apply it to the production database.
Production environment - This is the live environment for the company which is critical for business. No testing should be applied in the production environment.
Yes any junior DBA can administration the production database but in a limited domain. He/She must be guide by a senior DBA.

I dont have any database experience and I would like to start with a possible out come to become a database administrator not necessarily a programmer. As you can imagine what I would appreciate is any information on where to start with Oracle databases administrator since they are considered a stable and reliable products. Books either online or by purchasing them, opinions etc. are most welcomed. I have a background in programming with Java and system administrator but not with databases. To that end, any help on how to proceed to my database learning venture even as to suggest that I could get the OCA certification, after seeing the cert paths of Oracle would be appreciated.
First step was the right step, forum participation. You can post here all your requests, questions, setup, configuration, references, and answer are at a very high level.
I would suggest you this:
. Download Oracle RDBMS software, you can start easy with the Oracle XE edition, it is lightweight and very easy to setup and use. For advanced features you may want to use the Enterprise Edition.
. Download de SQLDeveloper, it will provide you a very good tool to access, database.
. Download the manual to have it handy in case you require it and you are offline.
. Start with the two-days dba manual http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14196/toc.htm and start practicing from here
. Once you are involved with this dba topic you can proceed to specific points, as described at the Certification Exam Guide. This way you'll start getting involved with very specific aspects of database administration and you'll be preparing for the OCA exam at the same time.
. Practice - practice - practice ... and ah! keep practicing.
. Questions, issues, and so on, we all here will be gladly to answer.

Oracle 11g 64 bit on Linux - Restore failure in production database
Hi guru,
We used to take full hot backup with the help of BackupExec of Symantec in our production database.We have two different oracle database (not cluster).
We defined same policy for both .We defined schedule on Symantec to take full hot backup every night of database on tap drive.At any point of time we maintain only 2 full backup for each database on tap and then recycle it.
Yesterday suddenly storage of database failed for both.?It was complete failure so we did not have any option but to restore last night full backup.
It has done successfully for one database but when we tried to restore second from last night backup it thrown error :
channel ch0: ORA-19870: error while restoring backup piece BE_9kjsfol6_1_1
ORA-19507: failed to retrieve sequential file, handle="BE_9kjsfol6_1_1", parms=""
ORA-27029: skgfrtrv: sbtrestore returned error
ORA-19511: Error received from media manager layer, error text
then we tried to restore backup of last to last night and it gave again error :
channel ch0: ORA-19870: error while restoring backup piece BE_9djsaman_1_1
ORA-19507: failed to retrieve sequential file, handle="BE_9djsaman_1_1", parms=""
ORA-27029: skgfrtrv: sbtrestore returned error
ORA-19511: Error received from media manager layer, error text
But we have seen log of Symantec at the time of backup and it said that backup has successfully completed.
right now I am in big trouble I tried almost all possible combination of symantec to restore database but got no success.I used script generated by symantec and tried to run that on RMAN directly but it is throwing same error.
Please help me if possible an throw some light on exception (as I understand it says it is not able to find some piece on tap but we have not touched tap and tap media is completely safe.)
I am pasting complete text log generated by Symantec at the time of restore attempt:

Creating standby database from ASM production database in standard edition
Hi,
I am using oracle 10g release 2 standard edition. I recently created a database instance and wanted to create a standby database instance. After sorting out how to achieve this without managed standby and data guard I finally got it working and the shipped archive logs are applied and working well on the standby database.
Now I am thinking of re-creating my production database and using ASM for storage managment. By doing this can a standby database still be created from a primary database using ASM? I want to be sure I can before I commit to using ASM for the production instance and manually creating a standby database from that instance.
Note: I am using standard edition not enterprise edition.Hi
For Oracle SE standby, you can visit www.anbultechnologies.co.uk , they have a brilliant product name DRMC which is Automatic disaster recovery solution with automatic failover in case primary goes down due to any reason.
We are using this product for more than 2 years and it works like a dream using Oracle Standard Edition. We have depolyed more databases and Standby solution within the prices of 2 EE edition licenses.
You can give ma try as well.

Changes are not reflected in Staging or Production Database - BCC
Hi,
I changed an asset from product catalog and able to see successful deployment in BCC. But, I am not able to see the changes in Staging or Production database.
I see only changes in Versioned Database.
Did the following things to see if thee is any error but there is no error during this operations.
1) Enabled all the logs for DeploymentManager, DeploymentServer.
2) Ran the CatalogMaintenanceService.
Please help me in resolving this issue.
Thanks,
DKAPAdding to Desai, check for the repository mapping in agents, i.e in your production agent, you need to map the repositories to production repositories. For example ProductCatalog should be mapped to ProductCatalogproduction, similarly in Staging agent as well.

Production database version 10.1.0.3 to 10.2
We are planning to upgrade the production database version 10.1.0.3 to 10.2 version.
Please provide the link to download the any standard document related to upgrade the oracle version 10.1.0.3 to 10.2.You can directly upgrade 10.1.0.3 to 10.2.0.2 by using 10.2.0.2 complete software distribution but not 10.2.0.2 patch set.
10.2.0.2 Patch set requires 10.2.0.1 base release first.
To proceed with the upgrade review instructions from Oracle Database upgrade guide 10.2 from OTN.

How to apply row level security against the database administrator
I would like an advice in applying row level security against the database administrator. We need to prevent DBA from editing data in some table rows or have any indication that data was corrupted.
There is no problem in viewing the data so we considered one way hash function or digital signature which will be stored in the same table, but we see following disadvantages:
HASH - DBA may use the same hash function to update the stored data after he changes the sensitive row.
Digital signature - the is a need to manage and keep the private key in a safe place outside of DB
Is there additional ways to achieve the aim?Does VPD helps to prevent from DBA to edit/view a data in specific rows?Yes.
If I correctly understand, DBA has full access to security policy used by VPD to control the access and can grant himself privileges that I don't want.You can to define which users can be exempt of the politics, for the context or by Grant EXEMPT.
This includes DBAs.
The simple fact of being DBA doesn't guarantee the exemption.
Everything goes to depend of the VPD config. -
Adding new column to production database
I have to add a new timestamp column, that defaults to the current date/time, to an existing production database. The table is large - 150M records. I am trying to understand the ramifications of adding a new column to a table this large that gets hit often, mostly with inserts and reads. The column does allow null values and I am not going back and populating existing records with a value. Basically, I am looking for some best practice guidelines - how to prepare, what to expect, what other processes should be followed along with this schema update.
Radiators wrote:
Thanks, I have not found any %TYPE or %ROWTYPE dependencies on the table I am altering. But at the same time I do not understand how these types of dependencies would invalidate packages. I wouldn't be breaking any %TYPE dependency because I am not dropping columns, only adding a new one. And according to documentation for %ROWTYPE - "If columns are later added to or dropped from the table, your code can keep working without changes." Can you point me to Oracle documentation that describes your concern in detail? Thanks.you can test it yourself

SQL> you should also consider the chance that some where if people are using "select * into" using this table, which will fail since you added new column. i don't see any unusual performance bottlenecks by adding a new column. in case of the backups, yes the earlier backups will not have the column. if you restore it, you will see earlier table structure itself. i have one specific question. why are you not attempting this in development/test environment first? even if it is a simple insert, it's always important to do it in test environments before attempting on production db. one thing for sure i know is, after adding column, you will have to recompile all the invalid dependencies. i think, it's better if you attempt it in test db and come up with any issues you see rather than asking a general question where problematic scenarios are plenty and rarely unknown before hand. -
Daily export backup (via datapump) of a 600GB production database
Hi Guys,
I have a 600GB DB.
10G Database.
Currently I have daily rman backup to tape.
Based on your experience, should i bother to perform a daily export of production database of such size?
Do u think it's useful?
thanksFran wrote:
All depends, what do you want to do? Do you have enough space to save a backup and export daily?
In my opinion with one backup is enough to save your database. I'm sorry, I can't agree with that. I've been in situations where the first, second and THIRD backup sources have been unavailable in the event of a Production restore. I had to go to Plan D and cross my fingers (and sweat a lot). That might be overkill, but you should never rely on just one backup method/source for Production data.
Not only that, but, obviously, you can also use an export of the data and import into another database or a schema inside the database in case you need to address any logical corruption. We also use the exports to refresh test databases.
We have many similar sizes of databases and we take exports weekly, instead of daily. An export will be an incomplete backup, obviously, though you can ensure consistency by giving it an SCN to use as a datapoint. You can also run Data Pump in parallel which does speed things up.
If you use it as part of your backup strategy, I'd make sure I had regular backups of the parameter file and the controlfiles (both binary and trace). I'd also make sure I had regular txt files showing the necessary information for the tablespaces and the datafiles which you can use to recreate the files in case you needed to.

Adding a Dialog instance to a live production database.
We are adding a number of new App servers to a ECC6 7.0 Live production database but we don't have enough confidence in the in the information in InstGui and install guide that it will not over write the /sapmnt/SID/exe of the running CI.
Has anyone done this and is just down to not selecting the unpack Kernel and oracle client check boxes in the Parameter Summary?
Cheers
ChrisHi,
>If parameters are set correctly it shouldn't ask you to unpack exe files.
>DI should get all exe files from CI and it will do the same copy again whenever it gets restarted.
Well, yes if only, the DI use the same kernel as the CI...
For example we run our ECC6 production system with a CI on Windows 2003 64 Itanium and the DI on Windows 2003 x86_64.

What is the Best way to extract a subset of data from a Production database
Hi,
One of our cleint want to to extract a subset of data from a Production databases in order to build a dev or test database. Since it is a banking sector they do not want to clone the db.
Can anybdoy suggests any tool or any info
Regards
ManojDataBee is one option. Depending on circumstances, you may also want their DataMasker utility in addition...
Of course, depending on your particular system and your particular requirements, this sort of thing can rather quickly get quite complicated since you may need very particular types of subsets of data...
