Response data if UsageType is MQIACF_USAGE_PAGESET

 

BufferPoolId (MQCFIN)

Buffer pool identifier (parameter identifier: MQIACF_BUFFER_POOL_ID).

Theis identifies the buffer pool being used by the page set.

ExpandCount (MQCFIN)

The number of times the page set has been dynamically expanded since restart (parameter identifier: MQIACF_USAGE_EXPAND_COUNT).

ExpandType (MQCFIN)

How the queue manager expands a page set when it becomes nearly full, and further pages are required within it (parameter identifier: MQIACF_USAGE_EXPAND_TYPE).

The value can be:

MQUSAGE_EXPAND_NONE

No further page set expansion is to take place.

MQUSAGE_EXPAND_USER

The secondary extent size that was specified when the page set was defined is used. If no secondary extent size was specified, or it was specified as zero, then no dynamic page set expansion can take place.

At restart, if a previously used page set has been replaced with a data set that is smaller, it is expanded until it reaches the size of the previously used data set. Only one extent is required to reach this size.

MQUSAGE_EXPAND_SYSTEM

A secondary extent size that is approximately 10 per cent of the current size of the page set is used. This may be rounded up to the nearest cylinder of DASD.

NonPersistentDataPages (MQCFIN)

The number of pages holding nonpersistent data (parameter identifier: MQIACF_USAGE_NONPERSIST_PAGES).

These pages are being used to store nonpersistent message data.

PageSetId (MQCFIN)

Page set identifier (parameter identifier: MQIA_PAGESET_ID).

The string consists of two numeric characters, in the range 00 through 99.

PageSetStatus (MQCFIN)

Current status of the page set (parameter identifier: MQIACF_PAGESET_STATUS).

The value can be:

MQUSAGE_PS_AVAILABLE

The page set is available.

MQUSAGE_PS_DEFINED

The page set has been defined but has never been used.

MQUSAGE_PS_OFFLINE

The page set is currently not accessible by the queue manager, for example because the page set has not been defined to the queue manager.

MQUSAGE_PS_NOT_DEFINED

The command was issued for a specific page set that is not defined to the queue manager.

PersistentDataPages (MQCFIN)

The number of pages holding persistent data (parameter identifier: MQIACF_USAGE_PERSIST_PAGES).

These pages are being used to store object definitions and persistent message data.

TotalPages (MQCFIN)

The total number of 4 KB pages in the page set (parameter identifier: MQIACF_USAGE_TOTAL_PAGES).

UnusedPages (MQCFIN)

The number of pages that are not used (that is, available page sets) (parameter identifier: MQIACF_USAGE_UNUSED_PAGES).
