How to do to identify foreground endevor users?
Can use any tool able to query enqueues held by users. For example, ENQ command available from TSO ISRDDN utility. Once in the ENQ panel, query for enqueues with:
SCOPE=STEP
MAJOR NAME=ENDEVOR (to identify endevor users) or EDIT-ELM (to locate Quickedit users)
MINOR NAME= literal 'IS ACTIVE IN SESSION n'
Each and every TSO user holding one of the above enqueues is using the dialogs and has potentially allocated and open the endevor datasets.
