2121 (0849) (RC2121): MQRC_NO_EXTERNAL_PARTICIPANTS

Explanation

An MQBEGIN call was issued to start a unit of work coordinated by the queue manager, but no participating resource managers have been registered with the queue manager. As a result, only changes to IBM® MQ resources can be coordinated by the queue manager in the unit of work.

Completion code

MQCC_WARNING

Programmer response

If the application does not require non-MQ resources to participate in the unit of work, this reason code can be ignored or the MQBEGIN call removed. Otherwise consult your system programmer to determine why the required resource managers have not been registered with the queue manager; the queue manager's configuration file might be in error.
