did You look at the -904 meaning...

emptying a huge table with huge columns by using a "delete * from table"
will be a silly waste of resources,

db2 will log all the activity for a ( useless ) restart

why not simply drop and create the table ???

if You insist on emptying it You must do it using a program and committing every few deletes

I' ll let You find the reasons by searching the forum for an explanation
( I checked and You can easily find it )

Hi jitu,

I think U have to give commit. For ex Give commit statement when count cross 1000 records. I thick It may solve your problem. I think I am right.

Instead of deleting huge records you can opt for REORG utility with purge criteria. This will avoid unnecessary logging overhead.

If you are using "delete * " then it is better to use LOAD REPLACE with dummy file rather than using delete statements.

To be on the safer side take image copy before performing all the operations so that you can recover the database if anything goes wrong.

Thanks
Amit
