Your DBA should be replaced by management.
That said if you have Oracle 9i or before have your DBA run
the following script:
utlxplan.sql
If 10g then catplan.sql
Both scripts are located at $ORACLE_HOME/rdbms/admin
Your DBA can email me directly if they have any questions such as where to find training. ;-)
Syntax and Explain Plan demos can be found in Morgan's Library
at www.psoug.org under Explain Plan. Use DBMS_XPLAN to display
explain plan results using one of the following scripts (located
in the same directory):
utlxplp.sql (parallel)
utlxpls.sql (serial)
utlxmv.sql & utlxrw.sql (materialized views)
Your DBA should send you these files if you can't access them.
