General detail :
This process is working fine with 9i but the moment we try to run it against 11g r2 is give error. This box has two homes with 9i and other 11g. I am thinking that could be an issue.

Below already tried :

Try to sent the Time zone varirable. ORA_TZFILE
Check the compatibility of versions.
Try to set oracle_home and LD_Library, oracle_sid in the scripts also.
