Monitoring an IMSplex

Monitoring the individual IMS systems in an IMSplex with CSL is not different from monitoring a standalone IMS system in any other environment. Monitoring the IMSplex as a whole, however, is different than monitoring an individual IMS system.

You can check system status by issuing the QRY IMSPLEX SHOW(ALL) command, which displays what IMS systems are active in the IMSplex and their statuses.

There are several other QUERY commands that are useful for monitoring certain aspects of the IMSplex. QUERY commands operate on an IMSplex-wide basis unless they are routed to specific IMS systems. For example:

• QRY TRAN QNT(GT,nn) where nn is a number you specify.

  The response displays the transactions that have a high queue count.

• QRY DB STATUS(ALLOCF,STOSCHD)

  The response displays the databases that have an allocation failure or that have been stopped. There are various other statuses that can be specified.
