TSO session hangs when generating an element in foreground

Issue/Introduction

Some team members TSO session hangs when generating an element in foreground.  It doesn't appear to have anything to do with the element because other folks can generate the same element in foreground without any issues.

Generating the element in batch works fine. 

Environment

Endevor

Cause

The users that experienced the problem of their Endevor TSO session hanging had "ismf = yes" coded in their userid.CLIST(#USERID) exec to allocate the ISMF modules, which resulted in ISP.userid.SISPLPA being added to the ISPLLIB concatenation.  This library was not APF authorized.

Endevor sets all TCBs non-dispatchable when executing BC1PTMP0 (for integrity reasons), with one exception; the TCB that executes ISPMAIN, with the additional requirement that the ISPMAIN program should be loaded from an APF-authorized library. ISPMAIN resides in ISP.SISPLPA, which is an APF-authorized library.

 

Resolution

Updating the userid.CLIST(#USERID) to update ismf = no.  Review your ISPLLIB concatenation to ensure the library containing ISPMAIN is APF Authorized.
