Response data

AlterationDate (MQCFST)
Alteration date (parameter identifier: MQCA_ALTERATION_DATE).

The maximum length of the string is MQ_DATE_LENGTH.

AlterationTime (MQCFST)
Alteration time (parameter identifier: MQCA_ALTERATION_TIME).

The time at which the definition was last altered, in the form hh.mm.ss.

The maximum length of the string is MQ_TIME_LENGTH.

CFConlos (MQCFIN)
The CFConlos property (parameter identifier: MQIA_CF_CFCONLOS).

Specifies the action to be taken when a queue manager loses connectivity to the CF structure. The value can be any of the following values:

MQCFCONLOS_TERMINATE
The queue manager will terminate when connectivity to the structure is lost.
MQCFCONLOS_TOLERATE
The queue manager will tolerate loss of connectivity to the structure without terminating.
MQCFCONLOS_ASQMGR
The action taken is based on the setting of the CFCONLOS queue manager attribute

This parameter is only valid from CFLEVEL(5).

CFLevel (MQCFIN)
The functional capability level for this CF application structure (parameter identifier: MQIA_CF_LEVEL).
Specifies the functional capability level for the CF application structure. The value can be any of the following values:
1
A CF structure that can be "auto-created" by a queue manager at command level 520.
2
A CF structure at command level 520 that can only be created or deleted by a queue manager at command level 530 or greater. This level is the default CFLevel for queue managers at command level 530 or greater.
3

A CF structure at command level 530. This CFLevel is required if you want to use persistent messages on shared queues, or for message grouping, or both.

4

A CF structure at command level 600. This CFLevel can be used for persistent messages or for messages longer than 64 512 bytes.

5

A CF structure at command level 710. This CFLevel supports shared message data sets (SMDS) and Db2® for offloading messages.

Structures are required to be at CFLEVEL(5) to support toleration of loss of connectivity.

CFStrucDesc (MQCFST)
The description of the CF structure (parameter identifier: MQCA_CF_STRUC_DESC).

CFStrucName (MQCFST)
CF Structure name (parameter identifier: MQCA_CF_STRUC_NAME).

The maximum length is MQ_CF_STRUC_NAME_LENGTH.

DSBLOCK (MQCFIN)
The CF DSBLOCK property (parameter identifier: MQIACF_CF_SMDS_BLOCK_SIZE).

The returned value is one of the following constants: MQDSB_8K, MQDSB_16K, MQDSB_32K, MQDSB_64K, MQDSB_128K, MQDSB_256K, MQDSB_512K, MQDSB_1024K, MQDSB_1M.

DSBUFS (MQCFIN)
The CF DSBUFS property (parameter identifier: MQIA_CF_SMDS_BUFFERS).

The returned value is in the range 0 - 9999.

The value is the number of buffers to be allocated in each queue manager for accessing shared message data sets. The size of each buffer is equal to the logical block size.

MQDSE_YES
The data set can be expanded.
MQDSE_NO
The data set cannot be expanded.
MQDSE_DEFAULT
Only returned on Inquire CF Struct when not explicitly set
