ASCHDATA subcommand — analyze APPC/MVS transaction scheduler data

Use the ASCHDATA subcommand to generate reports about the APPC/MVS transaction scheduler. This subcommand provides the following information:

Status of the scheduler
Subsystem name
Default scheduler class
Generic initiators, if any
Summary information for each class

See the APPC/MVS component in z/OS MVS Diagnosis: Reference for examples of ASCHDATA output.

Note: The reports generated by ASCHDATA contain information for IBM® diagnostic use. The IBM Support Center might ask you to provide this information for use in problem determination.

Report type parameters
Use these parameters to select the type of report. Specify only one; ASCHDATA produces the report type for each topic specified by a data selection parameter. If you omit a report type parameter, the default is ALL.
CLASS[(classname|ALL)]
Requests APPC transaction scheduler information for either a particular scheduler class or all scheduler classes. For this parameter, classname is a valid 1- to 8-character scheduler class name. If no class name is specified, information for all scheduler classes is displayed.
The class summary report displays the following information for each scheduler class:
Class name and status of each class, including:
Maximum and minimum number of initiators

Expected response time

Message limit

Total number of jobs waiting for processing

Total number of active initiators

Total number of active waiting multi-trans initiators

Total number of idle initiators
The class detail report includes information from the summary report and adds the following information:
For each job waiting to run, the job identifier, local LU name, partner LU name, TP name, FMH5 userid, and time the job started waiting to run.

For each active initiator, the address space identifier (ASID), TP start time, TP name, current job identifier, local LU name, partner LU name, and FMH5 userid.

For each active waiting multi-trans initiators, the ASID and TP name.

For each idle initiator, the ASID.
Data selection parameters
Data selection parameters limit the scope of the data in the report. If no data selection parameter is selected, the default is to present a summary report for all topics listed below.
DETAIL

Requests detailed information for each of the selected topics.

EXCEPTION

Requests a list of exceptional or unusual conditions for each topic. The list of exceptions contains information for IBM diagnostic use.

SUMMARY

Requests summary information for each of the requested topics.
Return codes
See Standard subcommand return codes for a description of the return codes produced by the ASCHDATA subcommand.
