CEMT INQUIRE and SET commands - IBM - AS/400

Descriptions of the combined CEMT INQUIRE and SET commands follow in alphabetic order of the name of the CICS resource. The options of each command are also described in alphabetic order.

CEMT INQUIRE AUTINSTMODEL

CEMT INQUIRE AUTINSTMODEL

Function
The INQUIRE AUTINSTMODEL command retrieves information about CICS autoinstall terminal model definitions in the control region. If you supply an autoinstall model name, details of that model are displayed. If you omit an autoinstall model name, details of all models in the control region are displayed. For more information about autoinstall,

There is no SET AUTINSTMODEL function. The INQUIRE AUTINSTMODEL screen also allows the use of the DISCARD AUTINSTMODEL function.

The status line shows the following information:

  • The name of the CICS autoinstall terminal model Auti (autoinstall-model-name).
  • Whether the CICS autoinstall terminal model is available for use (Ena) or not (Dis).

Required parameters

  1. AUTINSTMODEL
  2. The name (1–4 characters) of the autoinstall terminal model as specified by the CICSDEV parameter of the TCT.

CEMT INQUIRE|SET AUXTRACE

Flowchart

CEMT INQUIRE|SET AUXTRACE

Function
The INQUIRE AUXTRACE command retrieves information that controls the recording of the CICS auxiliary trace entries in the CICS control region. The SET AUXTRACE command controls the recording of CICS auxiliary trace entries in the CICS control region. The status line shows the following information:

  • Which of the CICS auxiliary trace user spaces is active: CUR (A) or CUR (B).
  • Whether the CICS auxiliary trace is active (Sta) or not (Sto).
  • What the CICS auxiliary trace does when the CICS auxiliary trace user space is full: switch to the next CICS auxiliary trace user space automatically (All) or stop the CICS auxiliary trace (Nos).

Required parameters

  1. ALL
  2. Automatic switching between the two CICS auxiliary trace user spaces is to occur as necessary until the end of the CICS control region, without the need for operator intervention.

CEMT PERFORM commands
There are two CEMT PERFORM commands:

  • PERFORM SHUTDOWN, to close a control region
  • PERFORM SNAP, to take a control region dump

CEMT PERFORM SHUTDOWN

CEMT PERFORM SHUTDOWN
Function: The PERFORM SHUTDOWN command shuts down the CICS control region. If PERFORM SHUTDOWN is entered with no other options, all CICS tasks are allowed to finish. Terminal sessions are allowed to terminate normally, before the CICS control region is shut down.
Required parameters:

  1. DUMP
  2. A CICS control region dump is produced before the completion of the termination process.
  3. IMMEDIATE
  4. The CICS control region is shut down immediately, terminating all active CICS tasks. This could cause CICS to abend if CICS tasks are still running.

CEMT PERFORM SNAP

CEMT PERFORM SNAP

Function: The PERFORM SNAP command produces a CICS control region dump.CICS/400 continues processing.
Required parameters:

  1. TITLE(xxx)
  2. A string of 1–32 characters. If the title includes spaces, the whole title must be enclosed within single quotation marks (’ ’).
    Note: The Title option is accepted but ignored. On other CICS platforms, the title is appended to the beginning of the dump. On CICS/400, it has no effect. It is included here for compatibility with other CICS platforms. The use of CEMT PERFORM SNAP prevents temporarily all other CICS tasks from running, so CICS users may experience delays in response.
