When started, the Process Symbiont automatically creates the PMDF_MR_NOTIFY device and logical name. As long as Message Router has been configured with /NOTIFY=PMDF_MR_NOTIFY on the PMDF-MR mailbox (typically named PMDF), no other configuration is required to enable local notification.
If you have defined more than one PMDF-MR mailbox in your local Message Router, you should configure each one with /NOTIFY=PMDF_MR_NOTIFY. The Process Symbiont will submit the pickup job for the appropriate PMDF-MR channel.
18.104.22.168 Notification Within a Local Message Router Cluster
If Process Symbiont queues are running on all nodes within a cluster,
nothing needs to be done beyond what was already discussed above in
If the Process Symbiont is not running on all systems in a cluster, you will need to ensure that the non-Process Symbiont nodes send their notifications to the Process Symbiont node. To achieve this when just one PMDF-MR mailbox is being used, on each non-Process Symbiont node, define a PMDF_MR_NOTIFY logical to point to the Process Symbiont system:
$ DEFINE/SYSTEM PMDF_MR_NOTIFY "node::""TASK=PMDF_MR_NTFY"""
nodeis the DECnet node name of a system running a PMDF Process Symbiont queue.
When using multiple PMDF-MR mailboxes when not all systems in the cluster are licensed for PMDF, you will need to use a PMDF-MR configuration as if the entire cluster is a remote cluster; see Section 40.6.3 below.
