Page set full

Problem

There is not enough space on a page set for one of the following:

• MQPUT or MQPUT1 calls to be completed

• Object manipulation commands to be completed (for example, DEFINE QLOCAL)

• MQOPEN calls for dynamic queues to be completed

Symptoms

The request fails with reason code MQRC_STORAGE_MEDIUM_FULL. The queue manager cannot complete the request because there is not enough space remaining on the page set.

The cause of this problem could be due to messages accumulating on a transmission queue because they cannot be sent to another system.

System action

Further requests that use this page set are blocked until enough messages are removed or objects deleted to make room for the new incoming requests.

Operator action

Use the WebSphere MQ command DISPLAY USAGE PSID(*) to identify which page set is full.

System programmer action

We can either enlarge the page set involved or reduce the loading on that page set by moving queues to another page set. See Managing page sets for more information about these tasks. If the cause of the problem is messages accumulating on the transmission queue, consider starting distributed queuing to transmit the messages.
