The user account in which the Oracle VSS Writer Service is running does not have the DBA privileges to log in to the Oracle instance.

VSS-00011: Connection to database instance <instance_name> failed.
Cause : The user account in which the Oracle VSS Writer Service is running does not have the DBA privileges to log in to the Oracle instance.
Action : Run the Oracle VSS Writer Service in a user account that can connect to the Oracle instance with DBA privileges.
I have assigned ora_dba group to the user that runs the Oracle VSS Writer Service which is the only Oracle solution but still getting
the above error. Was advised to raise the issue here that it is an OS issue. Pls help

The user account cannot access Oracle Database instance. And also how do you temporarily disable security software on the server.
Have you checked what I already asked for? "Try using the user account and access the Database Instance.
That will let you see if the problem is with the user account permissions or not."
If this does not help then you can contact Oracle as suggested by Dave.

Unable to copy database with different name in the same instance

I had a huge database and wanted to try some change optimization changes.
So wanted to make a copy of the database along with data in the same instance.
I have tried copy database wizard several times but always see the error as in attachment.
Can someone let me know how to troubleshoot further?
If this is not the correct way please suggest how do i copy a database with different name in the same instance along with data.

Hi Nandu,
From the screenshot, the error 1813 happens when corrupt database log is attempted to attach to the SQL Server. To work around this issue, please preform the following steps, for more details, please review this
blog.
1. Create a new database with same name which you want to recover. Make sure that the MDF file and LDF file have same name with previous database data and log file.
2. Stop SQL Server. Move original MDF file from old location to new location by replacing just created MDF file. Delete the LDF file of new location just created.
3. Start SQL Server. At this point, the database is in suspect status.
4. Make sure that system tables of Master database allows to update the values. Please note that you will be performing this in query window.
Use Master
go
sp_configure 'allow updates',1
reconfigure with override
go
5. Change database mode to emergency mode.
SELECT *
FROM sysdatabases
WHERE name = 'DatabaseName'
BEGIN
UPDATE sysdatabases
SET status = 32768
WHERE name = ' DatabaseName '
COMMIT TRAN
6. Restart SQL Server. Then execute the following DBCC command in query window to create new log file.
DBCC TRACEON (3604)
DBCC REBUILD_LOG(databasename,'c:\yourdatabasename_log.ldf')
GO
7. Reset the database status using following command.
sp_RESETSTATUS yourdatabasename
GO
8. Turn off the update to system tables of Master database running following script.
USE MASTER
GO
sp_CONFIGURE 'allow updates',0
RECONFIGURE WITH OVERRIDE
GO
9. Reset the database status to previous status.
BEGIN
UPDATE sysdatabases
SET status = (value retrieved in first query of step 5)
WHERE name = 'DatabaseName‘
COMMIT TRAN
GO
Make sure that you have done all the steps in order and restarted SQL Server where it is mentioned. Also run SQL Server Management Studio as administrator.(Right click-> Run as Administrator)
Thanks,

Is Program Global Area considered part of the Oracle Instance?

Is the memory structure Program Global Area considered part of the Oracle Instance?

Yes. A program global area (PGA) is a memory region that contains data and control information for a server process. It is a nonshared memory created by Oracle when a server process is started. Access to it is exclusive to that server process and is read and written only by Oracle code acting on behalf of it. The total PGA memory allocated by each server process attached to an Oracle instance is also referred to as the aggregated PGA memory allocated by the instance.

Can we change the Oracle instance name after confoguration.

Hi,
Has anyone tried changing the Instance name in Oracle after all the EPM components are configured.
I mean, after the system is up and running. Do I have to re-configure everything with new instance name?
If yes, what happens to data that was already there in the schemas?
Thanks in advance,
PM

Try the following
"On the machine hosting Shared Services, launch EPM System Configurator with the enableRegTask option: Make EPM_ORACLE_HOME/common/config/version_number the current directory and then launch configtool.bat|.sh -enableRegTask."
Cheers

Can we get the label name of the particular oracle field using open script

hi
can we get the label name of the oracle fields like column name ORDER NUMBER instead of ORDER_ORDER_NUMBER_0 when recording using openscript.

Good morning
Do you develop functional or load test scripts?
I don't think we can in both cases because this is really the name of the field + the index.
The zero refers to first line normally (then 1 for second line and so on).
"Order number" is maybe the display label which is not enough to recognize and interact with a field.
May I ask why you want this, then it could help me (us) to give you a good solution/workaround.
Cheers

Do we have a way to pull the license key from each Oracle Instance?

Dear all Oracle Experts,
I don't remember having to put the license key whenever I create the oracle instance. But is there away to pull it from the instance?

The difference between oracle software and other software such as microsoft, is that you don't need a license key to use the software, it is already open and fully functional. Oracle assumes customers will use the software they are allowed to use according to the license agreement. Customers would not be happy to have a lawsuit on their desktops due to improperly using copyrighted material.

Need help on Analysing the oracle code.

Hi,
Here i try to frame question, pls understand and give the best way to solve this.
We have running 20 to 30 unix scripts on daily basis. Each script has connected to oracle session and execute the corresponding packages & procedures. Some scripts are running at the same time. At this time oracle code in the script is not executed due to the table locking in other script. We have oracle trace files whenever the oracle code is not executed it shows the error and terminates the oracle session.
Examples:
Below the sample oracle execution log file. where we get the error and terminate the oracle session for your reference.

When you observe the above code, in unix script we try to connect to the oracle instance 2 times,
1st instance it was terminated with some error.
2nd instance it was successfully executed the oracle code.
By analysing the above log we found where the error was occured and the reson behind this also we know.
Assume the script called the procedure 'P_ARCHIVE_TBL' 5 times and the procedure works on different parameter(we could say different table) each time it was called.
Is it possible for us to know in which procedure call, it is errored out.
For any information pls revert us or ping me to this mail [email protected],
Regards,
Mani.

Hi,
You would need to have an exception block in your pl/sql code. You should also save table name in a variable when this procedure is called for every table. You should return/print the error code from exception block alongwith the table name and then you will be able to know that during which call of this procedure, the error was returned.

Communication from the Oracle Mngt service host to the agent host failed

Hi There,
I have installed Oracle 10.2.0.1 Grid software on a Solaris Zone. I plan to upgrade it to 10.2.0.5 very soon but would like to test the agent connection from a remote server first. I installed agent version 10.2.0.5 on the remote server. When I log into the oracle grid GUI I can see the host called "localhost" (this is not the correct name. It should be the server name) and the database instances on that server. However, when I select the localhost and press the configure button I get the following message:
Communication from the Oracle Mngt service host to the agent host failed. Refer to help for details localhost:cn=servername
The system administrators changed the /etc/hosts file to make sure the server was listed first fully qualified. For example: servername.domain.com instead of servername. However, this did no make a difference.
Could the issue be any of the following:
- Oracle 10.2.0.1 GRID does not work with 10.2.0.5 agents ?
- Oracle GRID in general don't work on SOLARIS Zones?
Please help.
Thanks.

OMS - -> Agent communication is not upward compatible
Downward, so Agent 10.2.0.1 --> OMS 10.2.0.5, should not be a problem.
In the last case however, you would not have access to any 10.2.0.5 Agent features.
So you can choose from 2 working options:
1 - Install the 10.2.0.1 Agent
2 - Upgrade your OMS to 10.2.0.5 (preferable)

Anybody any suggestions ...

Possible causes:
1. You are trying to start the database with the OS user that do not have the correct OSDBA or ORA_DBA group privileges.
Ensure that this user can start oracle
2. The do not have permission to write in the AUDIT_FILE_DEST directory or the limit set for this OS destination has been reached

Oracle8i on Windows 2000 Server - Oracle Instance don't auto start

I've installed the Oracle 8.1.7 on a Dell Pentium III server running Windows 2000 Server operational system. During the installation the Oracle Instance was started up, but after I reboot the computer, the Oracle Listener service and the Oracle service was started in automatic mode but the Oracle Instance do not started though.
My Oracle DBA teacher ask me to run Oradim and edit the Oracle configuration startup parameters. I did, but it didn't solve the problem. The values on Windows registry of the ORA_<SID>_AUTOSTART key is "true". The Dba Studio also gets information form the Oracle server and all the fields seems to be correct with auto-start option, but it didn't work out.
Can someone point me to any text I can read about installation troubles on Windows 2000 Server ?
Thanks in advance.
Jayme.

Hi
I don't have an 8i db to test on but I think it works the same as on 9i.
Check the following parameters in your registry in the key HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\HOME0:
ORA_<YOUR_SID>_AUTOSTART=TRUE
ORA_<YOUR_SID>_PFILE=<full path and file name of your init file>

Oracle instance crashing when enabling use_indirect_data_buffers=true

I have a Windows 2003 EE server (32bit) with 16GB of ram hosting a 10.2.0.2 Oracle server which is used to support a commercial software package (arcsight). I'm trying to get the Oracle backend to leverage the available system memory. I've read 50-60 different articles and posts regarding AWE and Oracle. I have successfully tuned the userva parameter in order to get the server to boot stable with the /3gb boot parameter. I've gotten to the point that the oracle instance will start up, but within about 30-60 seconds the instance will crash. Below is the information I believe that is relevant:

I appreciate any input on what to look at to further isolate this issue. I'd run into many other issues along the way (setting AWE_WINDOW_MEMORY to a proper size, setting db_block_buffers to a proper value, etc) that various forum searches helped resolve but I've not been able to find anything related to the errors I'm getting now. If I set use_indirect_data_buffers=false and tune back the db_block_buffers, the instance starts without any problems. Its just when I try and enable the use of AWE that I'm having a problem.

Just wanted to close out this tread in case anyone else runs into a similar problem. Turns out we ran into a bug documented in the below linked article (we're using AMD processors). Essentially needed to disable NUMA.
http://blog.csdn.net/orapeasant/archive/2007/06/05/1639532.aspx
excerpt ....
But please be aware of Bug 4494543 - affecting 10g and fixed in Oracle 11.0 ......
ORA-7445: CORE DUMP [ACCESS_VIOLATION] WITH USE_INDIRECT_DATA_BUFFERS=TRUE
Rediscovery Information:
1) Using 32-Bit Oracle on a 32-Bit Windows 2003 server running on an AMD Opteron 64-Bit chip.
2) You have set use_indirect_data_buffers=true in init.ora
Workaround: Basically disable NUMA feature on 32-Bit platform :-
1) Set ENABLENUMA = FALSE in Windows registry for the Oracle Home.
2) Set enableNUMA_optimizations = FALSE (init.ora)
Thanks for the help. We'll see if access to the extra memory will be useful or not .....
