SET TCLASS

Description

The SET TCLASS command allows you to set the maximum number of tasks in a particular transaction class that are allowed to run concurrently.

This command is limited to the numbered classes of earlier releases of CICS® and is retained for compatibility with those releases. The SET TRANCLASS command, described on page SET TRANCLASS, provides the same function and can be used for either the old numbered or new named classes.

Options

MAXIMUM(data-value)

specifies, as a fullword binary value, the largest number of tasks in the transaction class that are allowed to run concurrently. The value can be in the range 0 through 999. (This value corresponds to the MAXACTIVE value in a SET TRANCLASS command. See the description of this option on page SET TRANCLASS for a description of what happens when you change the MAXACTIVE limit.)

TCLASS(data-value)

specifies, as a fullword binary value, the number of the task class that you are changing. It must be in the range 0 –10.
