Hi,

For a requirement, I have created VSAM file with non-reusable option. I OPEN the file the with OUTPUT mode and able to load records into the file. This works fine first time but next time, when I try to reload the records with OUTPUT mode, I get an error Please help, how do I solve this now?

define the file with the REUSE option
or delete define it every time.

Please help, how do I solve this now?

The system is working as designed and how you indicated your data should be handled -- so why do you think there is anything to solve?

Thanks I've redefined the VSAM with REUSE option and it's working correctly now. I thought with NOREUSE, no other job than which creates it can use the VSAM file but it meant this:

REUSE / NOREUSE
REUSE parameter allows clusters to be defined that may be reset to empty status without deleting and re-defining them.

no other job than which creates it can use the VSAM file

This would be handled through your site security package (RACF, ACF/2, TOP SECRET).
