Hi, I have set up multithreading (max instances = 4) in the system msl file. However, I can only see one input file being picked up, not simultaneously. All audit logs and work files are unique. The same setup works on another server (Linux) but not on AIX. Any clues to fix this?

Hello:

I would suggest you also check:

Output files are unique

Input/Output backup option is turned off or if enabled, set to be unique

Map trace is turned off

Any run maps are designed to have unique output/audit/workspace, etc as well

Regards,

Tim
