Is there a way to issue CA Spool commands with JES or z/OS commands which should be issued by USER in Syslog/Userlog instead of going to ESF interface?
You can use MVS modify commands against the CA Spool started task. For example, some commands that can be issued in the SDSF/Syslog are:
/F caspoolstc,DS <- same as the /DS command in the CA Spool interface
/F caspoolstc,D,*ALL,V <- same information from the V panel of the CA Spool menu
Where caspoolstc is the name of the CA Spool started task.
The complete list of commands that can issued as modify commands against the CA Spool started task can be found in the following section of the documentation:
