Storage class properties
You can set attributes for storage classes. Storage classes are available only on z/OS®.
The following table lists the attributes that you can set.
For each attribute, there is a brief description of when you might need to configure the attribute. The tables also give the equivalent MQSC parameter for the ALTER STGCLASS and DISPLAY STGCLASS commands. For more information about MQSC commands, see Script (MQSC) Commands in the IBM® MQ online product documentation.
General page
The following table lists the attributes that you can set on the General page of the Storage class properties dialog.
Attribute | Meaning | MQSC parameter |
---|---|---|
Storage class name | Read-only. You cannot change the name of the storage class after it has been created. | STGCLASS |
Description | Type a meaningful description of the purpose of the storage class. See Entering strings in MQ Explorer. | DESCR |
PageSet ID | This is the page set identifier that the storage class is associated with. Type a number, from 00 to 99, two characters long. If this attribute is blank, the value is taken from the default storage class, SYSTEMST. | PSID |
QSG disposition | Read-only. The queue-sharing group disposition of the storage class. You cannot change the disposition of a storage class after it has been created. Queue manager means that the object definition is available only to the queue manager that hosts it; Group means that the object definition is stored on the shared repository and each queue manager in the queue-sharing group has a copy of the definition; Copy means that the object definition is the queue manager's copy of a definition in the shared repository. | QSGDISP |
XCF group name | If you are using the IMS™ bridge, this is the name of the XCF group to which the IMS system belongs. Type a name from 1 to 8 characters long. The first character must be an uppercase letter from A to Z; subsequent characters must be uppercase letters from A to Z, numbers from 0 to 9, or both. | XCFGNAME |

Passticket appl name | This is the application name that is passed to RACF® when authenticating the passticket that is specified in the MQIIH header. If you do not specify a value, the validation process uses the z/OS Batch Job Profile Name, which means that RACF validates using a profile in the form of MVSxxxx, where xxxx is the SMFID of the z/OS system on which the queue manager is running. | PASSTKTA |
