The adapter is a set of modules loaded into the IMS(TM) control and dependent regions, using the IMS external subsystem attach facility.
This procedure initializes the adapter and connects to the queue manager:
The process is the same whether the connection is part of initialization or a result of the IMS command /START SUBSYS.
If the queue manager is active when IMS tries to make the connection, the following messages are sent:
DFS3613I ESS TCB INITIALIZATION COMPLETE
CSQQ000I IMS/TM imsid connected to queue manager ssnm
When IMS tries to make the connection and the queue manager is not active, the following messages are sent to the IMS master terminal each time an application makes an MQI call:
CSQQ001I IMS/TM imsid not connected to queue manager ssnm. Notify message accepted DFS3607I MQM1 SUBSYSTEM ID EXIT FAILURE, FC = 0286, RC = 08, JOBNAME = IMSEMPR1
If you get DFS3607I messages when you start the connection to IMS or on system startup, this indicates that the queue manager is not available. To prevent a large numbers of messages being generated, you must do one of the following:
/STOP SUBSYS
If you do neither, a DFS2607I message and the associated CSQQ001I message are issued each time a job is scheduled in the region and each time a connection request to the queue manager is made by an application.
