6.51 ENABLEMONITORING

Valid For

GLOBALS

Description

Use the ENABLEMONITORING parameter to enable the monitoring of Oracle GoldenGate instances from Oracle GoldenGate Monitor and to collect trend data for Performance Metrics Server. It directs Manager to publish the monitoring points that provide status and other information to the Oracle GoldenGate Monitor clients.

Performance Metrics Server is used to monitor processes or services and collect statistics. To bring up the PMSRVR GLOBALS parameter, the ENABLEMONITORING UDP parameter must be set before starting the server in legacy. For Oracle GoldenGate MA it is done by default.

Before you enable monitoring on any given platform, see Introduction to Oracle GoldenGate Monitoring in the Administering Oracle GoldenGate Monitor for your database to make certain that the operating system is supported.

Note:

When monitoring is enabled on a UNIX system for a high number of Oracle GoldenGate processes (approximately 400), the system-imposed limit on the maximum amount of allowed shared memory may be exceeded. The message returned by Manager is similar to this:

WARNING OGG-01934  Datastore repair failed" reported during "start...

If this occurs, increase the kernel parameter kernel.shmall by eight times the default for the operating system.

Syntax

ENABLEMONITORING [ UDP ]
ENABLEMONITORING [ UDP ] [ UDPPORT portnumber ] [ HTTPPORT portnumber ]

UDPPORT portnumber

Valid with UDP for monitoring with a Performance Metrics Server (PMSRVR). Not valid for the BDB or LMDB monitoring modes.

The UDP listening port. It is optional. If provided, it overrides the existing GLOBALS parameter,REPOUDPPORT. If not provided, it uses the value of REPOUDPPORT as the port number.

You can change the UDP port of a PMSRVR in a secure deployment by adding the repoUPDPORT parameter to the GLOBALS file. For more information on configuring the UDP and TCP ports for PMSRVR, see How to Create Secure or Non-Secure Deployments.

HTTPPORT portnumber

Valid with UDP for monitoring with a Performance Metrics Server. Not valid for the BDB or LMDB monitoring modes.

The HTTP listening port for the service. It is optional. If not provided, 9004 is the default port number.
