CEMT SET TCLASS

Reset the maximum number of tasks and the purge threshold for a transaction class.

In the CICS Explorer, the Transaction classes operations view provides a functional equivalent to this command.

Syntax

Press the Clear key to clear the screen. There are two ways to start this transaction:
  • Type CEMT SET TCLASS (or suitable abbreviations for the keywords), followed by (value) or ALL. The resulting display lists the current status, similar to that obtained by using the CEMT INQUIRE TCLASS command. You can tab to the highlighted or blank fields and overtype them with the required values.
  • Type CEMT SET TCLASS (or suitable abbreviations for the keywords), followed by one or more attribute settings that you want to change. For example, cemt s tc(value) p(3) resets the purge threshold value to 3.

Typing ? at the beginning of either the first or second line gives a syntax prompt. Resetting the values takes effect immediately.

Options

(value)
Specifies the 8-character transaction class name. If no transaction class name is assigned, it defaults to DFHTCL00.
ALL
Specifies that any changes you request are made to all resources of the specified type that you are authorized to access.
MAXACTIVE (value)
Specifies the largest number of transactions in the transaction class that are allowed to run concurrently. The value can be in the range 0-999.
PURGETHRESH (value)
Specifies the limit at which the queuing transactions are purged for the transaction class. It can have a value in the range 0–1000000. Zero means that the transactions are not purged. A nonzero number n means that the first (n-1) transactions to arrive are queued and the nth is purged.
