This chapter describes the issues and problems encountered with running OCM's Support Hub (Repeater) feature. The following issues are addressed:
The OCMREPEATER.PROPERTIES file within the ${ORACLE_HOME}/sysman/config directory will allow you to debug certain connection related issues. This section illustrates the contents of this file and how to change certain parameters for debugging the Oracle Support Hub (also known as the OCM Repeater).
Note:
This property file is not the same as theCOLLECTOR.PROPERTIES file found for OCM. One sets properties for the Support Hub, the other for the OCM collector.To enable debug tracing for the Oracle Support Hub:
Edit the ${ORACLE_HOME}/sysman/config/OCMREPEATER.PROPERTIES file. From the listing of available parameter below, adjust:
log4j.rootCategory=WARN, Rolling
to be:
log4j.rootCategory=DEBUG, Rolling
For example:
log4j.appender.Rolling=org.apache.log4j.RollingFileAppender
log4j.appender.Rolling.File=${oracle.home}/sysman/log/ocmrepeater.log
log4j.appender.Rolling.Append=true
log4j.appender.Rolling.MaxFileSize=1000000
log4j.appender.Rolling.MaxBackupIndex=3
log4j.appender.Rolling.layout=org.apache.log4j.PatternLayout
log4j.appender.Rolling.layout.ConversionPattern=%d [%t] %-5p - %m%n
log4j.rootCategory=DEBUG, Rolling

Stop and restart the Oracle Support Hub to activate the debug mode. The easiest way to stop and restart the Oracle Support Hub is to execute the following command:
<OCM_REPEATER_HOME>/ocm/repeater/bin/ocmrepeaterctl configure
The ${ORACLE_HOME}/sysman/log/ocmrepeater.log file will now contain additional DEBUG messages.
Configuring an OCM Collector to run via the Oracle Support Hub (also known as the OCM Repeater) associated with Enterprise Manager Cloud Control 12c results in the following message:

Enterprise Manager Cloud Control 12c is configured with a proxy server to connect to Oracle, while the repeater is not yet set up to use the proxy server. For example:
export ORACLE_HOME=/u01/em12c/middleware12.1.0.2.0/oms export OCM_REPEATER_HOME=/u01/em12c/middleware12.1.0.2.0/oms export OCM_DOMAIN_PATH=/u01/em12c/middleware12.1.0.2.0/gc_inst/user_projects/domains/GCDomain $ORACLE_HOME/ocm/repeater/bin/ocmrepeaterctl status Oracle Support Hub - Release: 10.3.6.1.0 - Production Copyright (c) 2005, 2012, Oracle and/or its affiliates.
