The single predefined situation in this category monitors an MQ connection. The description and formula for this situation follow.
The CICS adapter can be automatically connected during CICS initialization by adding program CSQCCODF to the PLTPI. If CICS has been configured for use, the connection can have failed because of CICS authorization errors or an incorrect queue manager specification.
Formula
If the value of Connection_Status equals Inactive then situation CICSplex_MQInactive_Warning is true.

Formula
If the value of Connection_Status equals Inactive then situation CICSplex_MQInactive_Critical is true.
There are eight subtask TCBs available for MQM requests. If all TCBs are busy, transactions can have to wait for their message queuing requests to be processed. A high number of busy TCBs does not necessarily result in CICS performance problems.
Formula
If the value of Busy_TCBs is greater than 6 and the value of Busy_TCBs is less than or equal to 8 then situation CICSplex_MQBusyTCBs_Warning is true.
