GoldenGate 12.2 – Installation of the monitoring agent

As described in my last post, GoldenGate Studio requires the monitor agent on each GoldenGate instance. The goal of this agent is to allow GoldenGate Studio to interact with GoldenGate, for example, to deploy a new solution.

So lets start with the installation of the agent.

Download

The first step is to download the monitor agent (Oracle GoldenGate Monitor). It is available here.

Install_agent_monitor_8

Installation

The second step is to install the product.

After you have transferred the installer to the server decompress it.

oracle@srvoracle:/tmp/ [DB1] cd monitor/
oracle@srvoracle:/tmp/monitor/ [DB1] ll
total 420092
-rw-r--r-- 1 oracle oinstall 430166267 Feb 29 13:32 fmw_12.2.1.0.0_ogg_Disk1_1of1.zip

Archive:  fmw_12.2.1.0.0_ogg_Disk1_1of1.zip
  inflating: fmw_12.2.1.0.0_ogg.jar

-rw-r--r-- 1 oracle oinstall 430166267 Feb 29 13:32 fmw_12.2.1.0.0_ogg_Disk1_1of1.zip
-r-xr-xr-x 1 oracle oinstall 430387063 Oct 14 08:33 fmw_12.2.1.0.0_ogg.jar

For launching the installer it is mandatory to have at a minimum Java version 8 (1.8). If this is not available it can be downloaded here.

To start the installation, launch the fmw_12.2.1.0.0_ogg.jar.

oracle@srvoracle:/home/oracle/Downloads/jdk1.8.0_73/bin/ [DB1] ./java -jar /tmp/monitor/fmw_12.2.1.0.0_ogg.jar 
Launcher log file is /tmp/OraInstall2016-02-29_01-39-26PM/launcher2016-02-29_01-39-26PM.log.

Preparing to launch the Oracle Universal Installer from /tmp/OraInstall2016-02-29_01-39-26PM
Log: /tmp/OraInstall2016-02-29_01-39-26PM/install2016-02-29_01-39-26PM.log
Logs successfully copied to /u01/app/oraInventory/logs.

The OUI (Oracle Universal Installer) will start. On the first screen just click on the next button.

Install_agent_monitor_1

On the next screen, we can choose the option for the updates. In my case, I leave the option to skip the auto updates.

Install_agent_monitor_2

Fill up the software location desired for GoldenGate agent.

Install_agent_monitor_3

Select the option to install only the agent monitor.

Install_agent_monitor_4

The OUI will test the system configuration and the java version.

Install_agent_monitor_5

The OUI provides a summary of the configuration. Click on next button, if all is ok.

Install_agent_monitor_9

The installation is done.

Install_agent_monitor_6

At the end OUI provides a summary of the installation with the location of the logs.

Install_agent_monitor_7

Now GoldenGate agent is installed.

Configuration

Create instance

To create the instance of the agent, go where the binaries have been installed. In this example, it is /u01/app/oracle/product/jagent/oggmon/ogg_agent.

After that, launch the script createMonitorAgentInstance.sh.

oracle@srvoracle:/u01/app/oracle/product/jagent/oggmon/ogg_agent/ [DB1] ./createMonitorAgentInstance.sh 
Please enter absolute path of Oracle GoldenGate home directory : /u01/app/oracle/product/12.1.0/gg_1
Please enter absolute path of OGG Agent instance : /u01/app/oracle/product/12.1.3.0/jagent
Please enter unique name to replace timestamp in startMonitorAgent script (startMonitorAgentInstance_20160229140552.sh) : 2
Sucessfully created OGG Agent instance.

Create password

The agent needs a password to work. All the passwords will be stored in a wallet. For this go to the ORACLE_HOME_AGENT/bin. In my case, /u01/app/oracle/product/12.1.3.0/jagent/bin.

Launch the script pw_agent_util.sh.

oracle@srvoracle:/u01/app/oracle/product/12.1.3.0/jagent/bin/ [DB1] ./pw_agent_util.sh -jagentonly
Please create a password for Java Agent: 
Please confirm password for Java Agent: 
Feb 29, 2016 2:18:55 PM oracle.security.jps.JpsStartup start
INFO: Jps initializing.
Feb 29, 2016 2:18:56 PM oracle.security.jps.JpsStartup start
INFO: Jps started.
Wallet is created successfully.

Enable monitoring

To enable the monitoring, launch ggsci command and edit the GOLBALS parameter file.

oracle@srvoracle:/u01/app/oracle/product/12.1.3.0/jagent/bin/ [DB1] ggi 

GGSCI (srvoracle) 2> edit params ./GLOBALS

GGSCI (srvoracle) 4> view params ./GLOBALS

GGSCHEMA ggadmin
CHECKPOINTTABLE ggadmin.checkpoint
ENABLEMONITORING

Now restart the ggsci command and the jagent appears when doing an “info all”.

oracle@srvoracle:/u01/app/oracle/product/12.1.3.0/jagent/bin/ [DB1] ggi

GGSCI (srvoracle) 1> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     STOPPED                                           
JAGENT      STOPPED

To finalize, delete the datastore and recreate one.

oracle@srvoracle:/u01/app/oracle/product/12.1.3.0/jagent/ [DB1] ggi

GGSCI (srvoracle) 1> delete datastore
Are you sure you want to delete the datastore? yes

2016-02-29 14:33:30  INFO    OGG-06492  Datastore deleted.

GGSCI (srvoracle) 2> create datastore
Profile 'Trace' added.

2016-02-29 14:33:55  INFO    OGG-06489  Datastore created.

Now you can start the manager process and the jagent.

Conclusion

Now that the agents have been installed on each instance, all the prerequisite for GoldenGate Studio are met.

In the next blog, I will show you how to use GoldenGate Studio to deploy a solution
