List of Events Generated

submitted transaction submitted

started transaction being executed

complete transaction completed successfully

failed transaction failed to execute

error transaction completed but there were errors

In the case of a transaction completing with errors (a link error test or

boundary scan, for example), details of the failures are added to the

transaction outputs table.

class = event type = escalation

The name contains the name of the event being escalated and the

description contains did not complete. If a handler is registered,

it is called with a description of the eventthat was not handled. The

handler should pass the event to an external management agent.

class = server type = status

The description contains information on errors that occurred when

starting the server.

8.3.1 Extending the RMS Event Handling Mechanism

The RMS event handling mechanism is open and extensible. New event types and

handlers for them can be added on a site-by-site basis. Forexample, you might run a

periodic ﬁle system status check on each node, execute a local cleanup script and post a

ﬁle system event to RMS if the free space in the ﬁle system dropped belowa prescribed

level. The handler script could perform partition-wide or machine-wide cleanup and post

a notiﬁcation of the problem via email or an SNMP message.
