The VSAM profiles datasets are under a High Level Qualifier(HLQ) that user doesn't have access to read/update. Is it possible to override the name and specify the one that user can allocate and use instead? If not, is it possible to prevent the user's session from trying to open it every time he/she uses the tool? The purpose for all this is to get rid off the ACF2 error and DBG550J3W message.
The simplest solution is to delete the line in the INSIGHT CLIST that allocates the profile data set. The product runs just fine without it (except that the "What's new" screen when first entering the UI-User Interface will always display). ALLOC DDNAME(INSPROF) DA('your.insight.profile.dataset') SHR is the line that can be deleted.
