Transaction class definition attributes

The transaction class definition attribute descriptions are:

Description
(Optional.) Specifies a 1- to 30-character description of the resource.
Maxactive
specifies the maximum number of transactions in this transaction class that are allowed to be active. You must specify a MAXACTIVE value when you define a transaction class, in the range 0 through 999.
Name
Specify a 1- to 8-character name for the transaction class definition.
Purgethresh
This is an optional purge threshold for the transaction class; it defines a threshold number at which transactions queuing for membership of the transaction class are purged. Specify it if you want to limit the number of transactions queueing in this transaction class. It can have the following values:
NO
The size of the queue is unlimited (other than by the storage available to attach tasks).
number
The purge threshold number in the range 1--1 000 000.

If you specify this as 1, no transactions are allowed to queue. If you specify it as any other number (n), the size of the queue is restricted to number-1. All new transactions attached after the limit of n-1 is reached are purged.

RESGROUP
(Optional.) Specify the name of an existing resource group to which the definition is to be automatically added.
User data
(Optional.) Thre 8-character fields provided for any site-specific data related to the transaction class. CICSPlex® SM makes no use of this user data.
Version
(Optional.) Specify an integer in the range 1 through 15. Specify 0 or leave blank for CICSPlex SM to assign the first available version id in the range 1 through 15.
