11.1 Troubleshooting High Availability
11.1.1 Remote EM Agent is not able to Connect to Oracle GoldenGate Agent
In a High Availability environment of the node cluster, Oracle GoldenGate instance can relocate to a different machine in case of a classic instance. In the relocate scenario, the Enterprise Manager Agent of the previous machine continues to serve the Oracle GoldenGate Agent until the source/replica values are changed from Manage Agent UI from the Enterprise Manager console.
If the mgr port, pmsrvr port, and
jagent.rmi.port are blocked by the firewall, then the remote Enterprise
Manager Agent does not make a connection with the Oracle GoldenGate Agent and monitoring
stops.
For a seamless monitoring you need to ensure that the
mgr port,
pmsrvr port, and jagent.rmi.port were not blocked by a
firewall. To verify, execute the following telnet
commands:telnet gg-VipName jagent.rmi.port curl -v telnet://gg-VipName:jagent.rmi.port nc -zv -w 5 gg-VipName jagent.rmi.port
