Sqlplus error?

Dear all,

When I called sqlplus using cron schedule job in unix, the following error occurred:

SP2-0642: SQL*Plus internal error state 2165, context 1804:0:0
Unable to proceed

SQL*Plus: Release 9.0.1.0.0 - Production on Sat Nov 8 03:40:03 2003

Is this sqlplus error or because of oracle 9.0.1.0.0 ? Do I need to patch this database? If so, where can I get the patch?

Thank you very much!

Its likely to be an environment problem - especially if using cron - make sure your script exports $ORACLE_HOME, $ORACLE_SID and also has $ORACLE_HOME/bin in its $PATH.
