SHOW PROCESS
• TID=tid
Specifies the transaction for which information is to be displayed. If you omit
the TID option, the SHOW PROCESS/TRANSACTIONS command displays
information about all transactions for the process.
If you omit these options, the SHOW PROCESS/TRANSACTIONS command
displays all information about all transactions for the process.
Note that the SHOW PROCESS/TRANSACTIONS and SHOW
PROCESS/PARTICIPANTS commands display the same information about
transactions, but in different orders. The SHOW PROCESS/TRANSACTIONS
command walks down a transaction queue. The SHOW
PROCESS/PARTICIPANTS command walks down a resource manager queue.
/VECTOR_REGS
Displays the saved process vector registers.
/WORKING_SET or /WSL
Displays the working set list of the process.
Description
The SHOW PROCESS command displays information about the process specified
by process-name, the process specified with the /INDEX qualifier, the system
process, or all processes. By default, the SHOW PROCESS command produces
information about the SDA current process, as explained in Section 4.
The SHOW PROCESS command performs an implicit SET PROCESS command
under certain uses of its qualifiers and parameters, as explained in Section 4,
Section 5, and Section 6. If you use the SHOW PROCESS command and name
a process that is the current process on a CPU, SDA temporarily assigns the
symbols shown in Table SDA–9 to the values in the process. You can then refer
to those symbols when you use the FORMAT command.
The default of the SHOW PROCESS command provides information taken
from the software process control block (PCB).

This information describes the
following characteristics of the process:
• Software context
• Condition-handling information
• Information about interprocess communication
• Information about counts, quotas, and resource usage
Among the displayed information are the PID, EPID, priority, job information
block (JIB) address, and process header (PHD) address of the process. SHOW
PROCESS also describes the resources owned by the process, such as event
flags and mutexes. The ‘‘State’’ field records the current scheduling state of the
process; in a multiprocessing system, the display indicates the CPU ID of any
process whose state is CUR.
The SHOW PROCESS/ALL command displays additional process-specific
information, also provided by several of the individual qualifiers to the command.

This is the first display provided by the /ALL qualifier and the only display provided by
the /PCB qualifier.
