Lizette,

Is Setsys debug what you're looking for?

Setsys debug
Enable exits to test
Test function using exits
Disable exits
Setsys nodebug

Release Hardcopy
Examine activity logs for the effects of testing exits.

No need for a second HSM.

Subject: Re: Multiple HSM in one LPAR ?

Glenn,

Is there any safe way to test HSM exits without having a TEST LPAR?  So if I 
only had an LPAR but needed to validate my code for an HSM Exit, any way to do 
that safely?  Or would it be safer to bring up a new sysres set with the exits? 
 Or a new LPAR for testing?

Thanks

Lizette
