David -

Use cron. Nightly might be excessive. Kick off a shell script (remember that cron executes as root, so you need to set your environment) and create your own script dynamically (following code is use for backups also) in a manner like:

rebuild_index.sh

#!/bin/ksh

export PATH=$PATH:/u001/app/oracle/product/8.1.7/bin export ORACLE_SID=ifas
export PATH=$PATH:/$ORACLE_HOME/bin
export ORACLE_HOME=/u001/app/oracle/product/8.1.7 export ORACLE_BASE=/u001/app/oracle

sqlplus <<either use a password protection scheme or hardcode your access here> <<username>/<password>>> @/usr/local/bin/rebuild_index

exit

rebuild_index.sql

spool rebuild_index.sql
Select 'Alter index ' || index_name || ' rebuild;' from dba_indexes; # add selection caveats if desired
spool off
!chmod 777 /u014/oradata/ifastrn/rebuild_index.sql @/u014/oradata/ifastrn/rebuild_index

exit

Lots of variations possible.

Nightly? That is a lot. Are you really entering that much data on a daily basis?

     Does anyone have any good scripts for rebuilding indexes nightly on
     Solaris UNIX that they'd be willing to share?  Also, in your
     experience is it better to run this through UNIX cron jobs than using
     the Oracle OEM job scheduler?  I suspect the cron job will be the
     favorable answer.


     Thanks in advance,
