Other temporary storage security considerations
You can define
the queue names on the PREFIX attribute of the TSMODEL resource definition
as follows:
- By specifying a fully identified name that exactly matches the queue name specified on a READQ TS or WRITEQ TS command. This can be from 1 to 16 alphanumeric characters.
- By specifying a generic name, or prefix, that corresponds to the
leading alphanumeric characters of a set of queue names.
It follows that a prefix can only be from 1 to 15 characters, because if you specify the full 16 characters for a queue name, it must be the name of a specific temporary storage queue.
When a CICS® application issues a temporary storage command (for example, DELETEQ TS, READQ TS, or WRITEQ TS) and temporary storage security is in effect, CICS searches for a TSMODEL resource definition that corresponds to the leading characters of the queue name.
Note that if you include hexadecimal characters in a temporary storage queue name, unpredictable results may occur. Also, if a temporary storage queue name contains an imbedded blank, RACF® truncates the resource name to that blank.
