Rick,

Might there be a Scheduled Task or DBMS_Job that runs shortly after the load and deletes rows?

Just a thought - such "automagic" processes have bitten me in the past.

I have a recurring, repeatable problem I was wondering about its cause.

Oracle 9.2.0.1 on W2K Professional (SP2) Dell Optiplex workstation Pentium 4

Step 1 - I do an SQLLDR process that loads 88640 rows to a table Step 2 - SQL*Plus session - SELEC COUNT(*) from the table returns 88640 rows
Step 3 - Do an EXP on the table (to allow fall back to this point) - only exports 87257 rows
Step 4 - SQL*Plus session again - SELEC COUNT(*) from the table returns 87257 rows

No one else has access to the database. There are no unusual entries in the alert log.
There is nothing I have found in the UDUMP or BDUMP directories that would help.

Has anyone else experienced this??

Thanks

Rick Weiss
