Example Participant information request and message

The message provides information about jobs running in the defined address space. The displayed information is divided into Job information and Pipe Information.

Example

To request participant I/O information for ASID 82 enter the following command:

F MBOP,DISPLAY ASID=82

The following figure is an example of the participant information message.

The following tables describe the fields in the participant information message.

Job information fields describes the Job information fields
Pipe information describes the Pipe information fields

Job information fields

Field	Description
ASID	Address space number (in decimal) in which the participant is executing
JOBNAME	Participant job name
JOBID	Participant job ID (number)
STEP-NUM	Current step number within the job (if this step accesses a pipe), or the number of the last step that accessed a pipe (if the current step does not access a pipe)

Pipe information

Field	Description
PIPE	Pipe (data set) name
ID	Unique pipe identifier–the first 8 characters of the pipe time stamp
TYPE	Participant type. Possible value is READER WRITER
PIPETYPE	Pipe type Possible values are: AUTOMATIC–Pipe was defined by using Job Optimizer Pipes rules. MANUAL–Pipe was defined by using subsystem parameters in JCL.STP2STP– Pipe was dynamically defined by Job Optimizer to implement parallel steps processing. INTERNAL–Pipe is used for Job Optimizer Pipes internal purposes. API–Pipe was defined by using the Job Optimizer Pipes API (for future use). BTCHPIPE–Pipe is a BatchPipes-compatible pipe.
LAST-ACT	Time of last operation
STAT	Participant status Possible values are: AFT-EOF–End-of-file was sent or received by this participant. UNC-CLOS–Close was performed following a previous error (unconditional close). DEFRCLOS–Deferred close was performed. UNC-DALC–Deallocation was performed after a previous error (unconditional deallocation). IMM-ERR–An error in the pipe caused the participant to abend immediately. OFI/DLY–For a writer, the writer writes only to the physical file. For a reader, the reader continues its process regardless of an error in the pipe but abends at the end of the process. IGN-ERR–An error in the pipe was ignored by this participant.
PHASE	Current phase of the pipe participant (for internal use)
PRT-FLG	Participant-related error indications Possible values are: REJECT–Participant was unable to join the pipe for various reasons. USRERROR–Participant encountered an error. INTABDON–Pipe Handler abended this participant. DISTABND–Participant distributed its error to all other participants. When they receive the error, they should abend. TIMEOUT–Timeout expired, and the participant accepted that indication. PIPEIOE–The pipe I/O Error status was encountered. USRABEND–Participant abended during pipe processing.
PIPE-FLG	Pipe-related error indications Possible values are: PIPERROR–Pipe is in error. ABENDIMM–Pipe is in error. All participants should immediately abend. ERRDIST–Error was distributed from another participant. TIMEOUT–Timeout expired, and the participant was notified. PEERH–Participant is in error, and the error was handled and distributed to the other participants. PIPEIOE–Pipe I/O error occurred. NO-RDRS–All readers closed before receiving end-of-file. PIPECNCL - Pipe was canceled by the operator by using the F MBOP,CANCEL PIPE `=` operator command.
PIPE-FL2	Second pipe-related error indications. The possible value is FORCTERM indicating the Job Optimizer Pipes address space was terminated with FORCE option.
STEP-NUM	Step number within the job that allocated the pipe
DDNAME	Name of the DD statement that allocates the pipe
HOME-SYS	Name of the Pipe Home System (PHS). This system is where the pipe is managed.
TIMESTMP	Unique identifier of a pipe. Its value is determined when the first participant allocates the pipe.
FLAG1	Various indications Possible values are: RMT-PRT–remote participant (this participant runs in a system that is different from the PHS) GLB-PIPE–Global pipe FAST-PIP–Global pipe with only one writer SINGL-RD–fast pipe with only one reader
