After upgrading to 14.1, I have a customer reporting some panels on the MQ dashboard (option 9.5 after setting an MQ region) are valid data and some are showing the following error message -
MQSR002E*QPST MQCONN failed, MQRC_ADAPTER_CONN_LOAD_ERROR (2129,X'851')
The IBM Messages manual has this to say about this error:
2129 (0851) (RC2129): MQRC_ADAPTER_CONN_LOAD_ERROR
==================================================
Explanation
On an MQCONN call, the connection handling module could not be loaded, so
the adapter could not link to it. The connection handling module name is:
o CSQBCON for batch applications
o CSQQCONN or CSQQCON2 for IMS applications
This reason code occurs only on z/OS.
Completion Code
MQCC_FAILED
Programmer response
Ensure that the correct library concatenation has been specified in the batch
application program execution JCL, and in the queue-manager startup JCL.

You either have to Steplib to the library containing this module, or it has to be linklisted.
