This post is mostly for anyone at RheoData to use get a sense of how the Oracle GoldenGate Monitor Agent needs to be installed.  The approach taken is to ensure that it is installed via the -silent process making it easier to install when looking at CI/CD processes and needing to get the agent installed quickly.  This post is also intended to be high-level notes for myself for me to look at later if needed.

The steps to get Oracle GoldenGate Monitor Agent installed are as follows:

1. Download the Oracle GoldenGate Monitor Agent from OTN (here)

2. Unzip the downloaded zip file in a directory that is easily accessed.

$ cd /tmp
$ unzip fmw_12.2.1.2.0_ogg_Disk1_1of1.zip -d ./gg_mon

3. Create a response file and add needed information

$ cd /tmp/gg_mon
$ touch gg_mon.rsp

[oracle@rtlvedgo04 gg_agent]$ cat gg_mon.rsp
#DO NOT CHANGE THIS.
Response File Version=1.0.0.0.0
[GENERIC]
#The oracle home location. This can be an existing Oracle Home or a new Oracle Home
ORACLE_HOME=/u01/app/oracle/oem_agent/134000/agent_13.4.0.0.0
INSTALL_TYPE=GoldenGate Monitor Agent Installation
You have new mail in /var/spool/mail/oracle

4. Confirm Java 8 is available

$ which java
$ java -version

/u01/app/java/jdk1.8.0_202/bin/java

5. Install the Oracle GoldenGate JAgent

 /u01/app/java/jdk1.8.0_202/bin/java -jar ./fmw_12.2.1.2.0_ogg.jar -silent ./gg_mon.rsp

6. Monitor the installation of Oracle GoldenGate JAgent

Launcher log file is /tmp/OraInstall2021-12-06_04-17-03PM/launcher2021-12-06_04-17-03PM.log.

The installation of Oracle Fusion Middleware 12c GoldenGate Monitor & Veridata 12.2.1.2.0 completed successfully.
Logs successfully copied to /u01/app/oraInventory/logs.

7. Create the Agent instance

$ ./createMonitorAgentInstance.sh
Please enter absolute path of Oracle GoldenGate home directory : /u01/app/ogg/oracle19c/19100/core
Please enter absolute path of OGG Agent instance : /u01/app/ogg/oracle19c/19100/core/oggmon_agent/12.2.1.2/agent_inst
Please enter unique name to replace timestamp in startMonitorAgent script (startMonitorAgentInstance_20211206163005.sh) :
Successfully created OGG Agent instance.

8. Create the wallet for the Agent

$ cd /u01/app/ogg/oracle19c/19100/core/oggmon_agent/12.2.1.2/agent_inst
$ cd bin
$ export JAVA_HOME=/u01/app/java/jdk1.8.0_202
$ ./pw_agent_util.sh -jagentonly
Please create a password for Java Agent:
Please confirm password for Java Agent:
Dec 06, 2021 4:33:10 PM oracle.security.jps.JpsStartup start
INFO: Jps initializing.
Dec 06, 2021 4:33:10 PM oracle.security.jps.JpsStartup start
INFO: Jps started.
Wallet is created successfully.

9. Adjust the Agent to the environment where you are running it

$ cat ./Config.properties | egrep -v "^#|^$"
jagent.host=localhost
jagent.jmx.port=5555
interval.regular=60
interval.quick=30
monitor.host=localhost
monitor.jmx.port=5502
monitor.jmx.username=oggmsjmxusr
jagent.username=oggmajmxusr
reg.retry.interval=10
instance.query.initial.interval=5
incremental.registration.quiet.interval=5
maximum.message.retrieval=500
jagent.rmi.port=5559
agent.type.enabled=OEM
status.polling.interval=5
message.polling.interval=5
reg.retry.times=-1
jagent.backward.compatibility=false
jagent.ssl=false
jagent.keystore.file=jagentKeyStore
jagent.truststore.file=jagentKeyStore
jagent.restful.ws.timeout=15000
jagent.ggsci.timeout=30

10. Enable monitoring in the GLOBALS file

$ cd $OGG_HOME
$ vi GLOBALS

Add the parameter ENABLEMONITORING to the GLOBALS file.

11. Access GGSCI and verify that the JAGENT is available and start it if needed.

$ ./ggsci

GGSCI (rtlvedgo04.labcorp.com) 1> info jagent

JAgent is running.

GGSCI (rtlvedgo04.labcorp.com) 2> info all

Program Status Group Lag at Chkpt Time Since Chkpt

PMSRVR STOPPED

Note: in the above example, when using Oracle GoldenGate 12.3 or later the ENABLEMONITORING parameter will also enable Performance Metric Service.

After confirming that the JAgent has been started, you are done.  Hope this helps!

Enjoy!!
