21.1.1 Receiving restore_config Operations Fails Error

A restore_config operation fails.

Problem

A restore_config operation fails with the following error:

C:\OracleAS\IM_1128/dcm/bin/dcmctl.bat applyarchiveto -archive 
2004-11-29_11-23-18 -script 

ADMN-906025 
Base Exception:

it occurred then resync the instance
java.lang.Exception: Could not delete file
C:\OracleAS\IM_1128\j2ee\OC4J_SECURITY\application-
deployments\wirelesssso\jazn-data.xml. Please check file permissions.

at oracle.ias.sysmgmt.repository.DcmPlugin.commit(Unknown Source)

Solution

If you see error similar to "Could not delete file jazn-data.xml", execute the following steps:

• Stop all the OC4J processes using the following command:

  ORACLE_HOME/opmn/bin/opmnctl stopproc ias-component=OC4J
  
  

• Rerun the restore_config operation.

21.1.2 File-based Repository Restoration Fails

A file-based repository restoration fials.

Problem

File based repository restoration fails with the error indicating that the dcm daemons across the farm could not be restarted.

C:\fbfhost\backup_restore>bkp_restore.bat -m restore_repos -t 
2004-12-07_13-49-13 
 
C:\fbfhost\backup_restore>echo off 
Stopping dcm-daemon across the farm ... 
Importing file based repository ... 
Restarting dcm-daemon across the farm ... 
  Problem running command (Returned 150) 
  c:\fbfhost/opmn/bin/opmnctl @farm restartproc ias-component=dcm-daemon 
The file based repository has been restored. 
But, dcm daemons across farm could not be restarted. 
Please take the appropriate action. 
See c:\logs/2004-12-07_13-50-18_restore_repos.log for more info

Solution

At this point, the file based repository has been restored successfully. Now, perform the following steps on the repository host:

1. Stop the dcm-daemon process on the file based repository host:

   ORACLE_HOME/opmn/bin/opmnctl stopproc ias-component=dcm-daemon
   
   

2. Start the dcm-daemon processes across farm:

ORACLE_HOME/opmn/bin/opmnctl @farm startproc ias-component=dcm-daemon

21.1.3 Cannot Run a Cold Backup on Identity Manager or J2EE Instance

You cannot run a cold backup on Identity Manager or J2EE instance.

Problem

When backup_cold is attempted on IM or J2EE instance, the following error message is displayed:

C:\Product\OracleAS\SSO_1203\backup_restore>bkp_restore.bat -v -m backup_cold 
 
 C:\Product\OracleAS\SSO_1203\backup_restore>echo off 
   ======================================== 
 Running command: 
 C:\Product\OracleAS\SSO_1203/dcm/bin/dcmctl.bat whichfarm -v -script >> 
 C:\Product\OracleAS\SSO_1203\backups\log_path/2004-12-09_03-56-55_whichfarm.log 
 C:/Product/OracleAS/SSO_1203/backup_restore/config/config.inp: Invalid 
 'database backup_path' specified 
 VALUE_NOT_SET - No such file or directory 
 Consider using '-f' to force creation of this path 
 Failure: backup_cold failed

Solution

The backup_cold operation should only be used on the repository hosts - Metadata Repository instance and/or any instance hosting a file-based repository.

21.1.4 Failure Due to Loss or Corruption of OPMN.XML File

The loss or corruption of the opmn.xml file is causing a failure.

Problem

The loss or corruption of the opmn.xml file caused the following error:

ADMN-906025 
Base Exception:
The exception, 100999, occurred at Oracle Application Server instance
"J2EE_1123.stada07.us.oracle.com"

Resolution

Perform the following steps to restore the opmn.xml file:

1. Run

   bkp_restore.bat -m restore_config -t <timestamp>
   
   

2. If that command fails, stop the OC4J processes.

3. Rerun

   bkp_restore.bat -m restore_config -t <timestamp>
   

21.1.5 A restore_config Operation Fails

A restore_config operation fails or the ORACLE_HOME/j2ee/OC4J_SECURITY directory is deleted.

Problem:
