IPCS provides three subcommands to obtain diagnostic reports about
allocation and unallocation.
- The ANALYZE subcommand with the keyword RESOURCE lists the jobs
holding device groups and the jobs waiting for device groups.
- The VERBEXIT ALCWAIT subcommand looks at devices instead of device
groups, listing jobs that are waiting for devices.
- The LISTEDT subcommand displays information from the EDT.
z/OS MVS IPCS Commands gives the syntax for both
subcommands and z/OS MVS IPCS User's Guide explains
how to use the ALCWAIT and LISTEDT component analysis options of the
IPCS dialog.
