I found this issue when dealing with Oracle DB backup where backup of multiple DB instances failed with SBT error = 7011, errno = 2534, sbtopen: system error.

 We notice that In Script to run the Oracle offline DB backup , the path to TDP Oracle option file was not correctly mentioned which leads to option file error.

SBT error = 7011, errno = 2534, The error 2534 correspond to the TDP message =>

ANU2534E Option file error

We checked in RMAN script that  $TDP8i_DIR is not set to tdpo option file under /usr/tivoli/tsm/client/oracle/bin64 instead it was set to /usr/tivoli/tsm/client/oracle/bin.


/usr/tivoli/tsm/client/oracle/bin64 # cd $TDP8i_DIR
/usr/bin/ksh: /usr/tivoli/tsm/client/oracle/bin:  not found.

Solution: Set the correct path of tdpo option file in parameter $TDP8i_DIR so that it should look for tdpo option file under usr/tivoli/tsm/client/oracle/bin64.

You can also use tdpoconf showenv -tdpo_optfile=/location of opt file/ to see if there is any issue.
