Each SSM entry in IMS(TM).PROCLIB defines a connection from an IMS region to a different queue manager.
To name an SSM member, concatenate the value (one to four alphanumeric characters) of the IMSID field of the IMS IMSCTRL macro with any name (one to four alphanumeric characters) defined by your site.
One SSM member can be shared by all the IMS regions, or a specific member can be defined for each region. This member contains as many entries as there are connections to external subsystems. Each entry is an 80-character record.
The fields in this entry are:
SSN,LIT,ESMT,RTT,REO,CRC
where:
WebSphere MQ completion and reason codes are returned to the application if the WebSphere MQ problem occurs while WebSphere MQ is processing the request; that is, after the adapter has passed the request on to WebSphere MQ.
WebSphere MQ completion and reason codes are returned to the application if the WebSphere MQ problem occurs while WebSphere MQ is processing the request; that is, after the adapter has passed the request on to WebSphere MQ.
An example SSM entry is:
CSQ1,MQM1,CSQQESMT,,R,
where:
CSQ1 | The default subsystem name as supplied with WebSphere MQ. You can change this to suit your installation. |
MQM1 | The default LIT as supplied in CSQQDEFV. |
CSQQESMT | The external subsystem module name. You must use this value. |
R | REO option. |
WebSphere MQ parameters can be specified in keyword format; to do this you must specify SST=DB2. Other parameters are as described in Positional parameters, and shown in the following example:
SST=DB2,SSN=SYS3,LIT=MQM3,ESMT=CSQQESMT
where:
SYS3 | The subsystem name |
MQM3 | The LIT as supplied in CSQQDEFV |
CSQQESMT | The external subsystem module name |
