Format the trace with an IPCS CTRACE COMP(SYSOMVS) subcommand.
The OPTIONS parameter specifies the options that select trace records
to be formatted. Your formatting options depend to a great extent
on the tracing options you requested. Use the options to narrow down
the records displayed so that you can more easily locate any errors.
If the CTRACE subcommand specifies no options, IPCS displays all the
trace records.
- ALL
- Formats all events.
- CHARS
- Formats character special events.
- DEVPTY
- Formats pseudoterminal events.
- DEVRTY
- Formats OCS remote terminal events.
- EXCEPTION
- Formats exceptional events, such as recovery records or error
records.
- FILE
- Formats file system events.
- IPC
- Formats events for shared memory, message queues and semaphores.
- KERNINFO
- Formats the output to include a header for each record that includes
descriptive information regarding the system call, process ID, and
the module that requests the trace.
- LOCK
- Formats locking services events.
- PIPE
- Formats pipe events.
- PROCESS
- Formats process events.
- PTRACE
- Formats PTRACE events.
- SCCOUNTS
- Counts the number of syscalls that occur in the trace. Also counts
the number of function codes that occur in a trace. The outputs are
displayed in tables. Formatting is suppressed. The function codes
refer to the types of messages that are crossing between systems in
a sysplexed environment. In a non-sysplex dump, the functions code
table will be empty. You could run an application while collecting
CTRACE data, and then use this option to determine the frequency of
syscalls and function codes being made by the application.
- SEARCH
- Starting at the specified offset, searches trace entries for a
specific value and displays the matches. A CLIST called BPXMSCER is
provided to allow the search to be performed against specific entity
ids that will identify syscall exits that have failed.
- SIGNAL
- Formats signaling events.
- STORAGE
- Formats storage management events.
- SYSCALL
- Formats callable service layer events.
- SYSID(nnn)
- Formats sysplex system events. When this is requested by the user,
only those trace records that contain a sysplex system id will be
formatted and displayed. (nnn) is the sysplex number or name of the
system in the sysplex whose records will be displayed. See Example of CTRACE DISPLAY PARAMETERS panel for an example of a CTRACE DISPLAY PARAMETERS
panel and the SYSID option on that panel.
- XCF
- Formats XCF events.
