Hi community.

We recently configured the Oracle agent on a Linux machine, the instance is discovered and configured. But when checking the readiness, it gets the error below:

 

Connect string: /
SBT library path: /backup/catalyst/commvault/Base/libobk.so
RMAN failed to load SBT library [RMAN-03009: failure of allocate command on c1 channel at 02/24/2026 16:49:34 ORA-19554: error allocating device, device type: SBT_TAPE, device name: ORA-27211: Failed to load Media Management Library ]. Please run Check Readiness on the client to diagnose and resolve the issues.

 

Checking the logs, I see the lines below:

 

39612 9abc 02/10 16:15:29 ### SetOracleBaseEnv(6236) - Failed to execute script [/backup/catalyst/commvault/Base/Temp/orabase_39612.sh] returnCode [126] output [] errorStr [ERROR: ld.so: object '/backup/catalyst/commvault/Base/libCvDllFilter.so' from LD_PRELOAD cannot be preloaded: ignored.

bash: /backup/catalyst/commvault/Base/Temp//ulimitquery_67447.sh: Permission denied

 

Does anyone have faced the above errors?

Thank you.

Hi ​@Hansel.Flores 

What is the CV, DB and OS version?

Did you set unix group during Oracle iDA install?
