I ran a job, calling a shell script from Cloud Control on an AIX 5.3 host. This script in turn calls sqlplus and does some sql. Now I got the error in Cloud Control:
SP2-1503: Unable to initialize Oracle call interface
SP2-0152: ORACLE may not be functioning properly
It appeared that some environment settings were missing. In a note by IBM, I read that you might need LIBPATH defined. Check the note here: http://www-01.ibm.com/support/docview.wss?uid=isg3T1015835
Hence, my full script is :
sqlplus '/as sysdba' <
This worked fine. Hope this helps.
