Hi,

Actually i am taken backup (hot backup) from my production database. And successfully restored in my standby machine.

When collecting statistics from schema i am facing the below error message.

Quote:

Errors in file d:\oracle\admin\samidb\udump\samidb_ora_2440.trc:
ORA-12012: error on auto execute of job 123
ORA-06521: PL/SQL: Error mapping function

Post what you did. I mean, the exact statement used to collect statistics.
If you can afford, delete the existing statistics for the concerned table and collect again.

This could be a known issue and the recent versions may have this fixed.
Instead of estimate, use compute. Early versions of Oracle 9i had some random problems with estimate when used with GATHER_SCHEMA_STATS/GATHER_DATABASE_STATS
