Relinking the Oracle SBT Library

When the Oracle environment has some SBT library conflicts that causes the Commvault backups to fail, you must relink the SBT library to load the Commvault SBT library in the $ORACLE_HOME/lib path.

Before You Begin

Set the sNOSBTLIBNAME Additional Setting to Skip Passing SBT_LIBRARY to the Allocate Channel Command

Procedure

On the Oracle Agent host command line go to software_installation_folder/iDataAgent and run the Ora_install.sh file as a root user.
```
[root@dbserve22 iDataAgent]# ./Ora_install.sh
```
At the command prompt, type the Oracle user ID and press Enter.
```
Please enter ORACLE_USER ID: oracle
```
At the command prompt, type the user group and press Enter.
```
Please enter user group for oracle [dba]: oinstall
```

At the command prompt, type the Oracle home directory and press Enter.

Please enter ORACLE_HOME directory: /home/oracle/app/oracle/product/11.2.0/dbhome_1

At the command prompt, type the home directory of the Oracle root user and press Enter.
```
Please enter the home directory of user oracle [~oracle]: /home/oracle
```

At the command prompt, type n and press Enter.

Would you like to relink Commvault with different ORACLE_HOME now(y/[n])?n

Verify the SBT library is in the specified in the Oracle_HOME/lib directory. On the command line, go to Oracle_HOME/lib and type the following command:
```
ls -l /home/oracle/app/oracle/product/11.2.0/dbhome_1/lib/libobk.so
lrwxrwxrwx 1 root root 27 May 29 13:02 libobk.so -> /opt/commvault/Base/libobk.so
```

Result

The $ORACLE_HOME/lib path links to the Commvault SBT library.

To verify the SBT library path, run the following RMAN script:

run
{
allocate channel ch1 type sbt
trace 2;
}

If the script is able to load the Commvault SBT library, the following output is displayed.

allocated channel: ch1
channel ch1: SID=90 device type=SBT_TAPE
channel ch1: Commvault Systems for Oracle: Version 11.0.0(BUILD80)
released channel: ch1
