This chapter describes the tasks you perform to install and upgrade Oracle GoldenGate Monitor Agent from 11g to 12c or when upgrading the original JAgent that was delivered with 12c.
Note:
Do not follow the instructions in this chapter if you have installed Oracle GoldenGate Monitor Agent 12c for the first time; the upgrade occurs automatically.Use the following tasks to upgrade your existing Oracle GoldenGate Monitor Agent($OGG_HOME/dirjar
) 11g to 12c:
Task 2, "Backup the Existing Oracle GoldenGate Monitor Agent"
Task 9, "Removing the Previous Oracle GoldenGate Monitor Agent Software"
Obtain the product distribution by following the instructions in Section 1.4, "Downloading Oracle GoldenGate Monitor Agent."
Create a backup copy of your entire pre-upgrade Oracle GoldenGate Monitor Agent environment before you upgrade by copying the following to a backup location:
OGG_HOME
/cfg
folder
OGG_HOME
/dirjar
folder
OGG_HOME
/pw_agent_util.*
files
OGG_HOME
/jagent.*
files
OGG_HOME/dirwlt
directory
Configure your JRE as follows:
Set your $JAVA_HOME
environment variable to use your installed JRE.
Set $JAVA_HOME/bin
first in your $PATH
environment variable.
Verify that $JAVA_HOME
and $JAVA_HOME/bin
are setup correctly by running the following command:
java -version
The Java version is displayed and should be similar to the following:
java version "1.8.0_40" Java(TM) SE Runtime Environment (build 1.8.0_40-b19) Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)
Install Oracle GoldenGate Monitor Agent in a separate, standalone location using the instructions in one of the following dependent on your database:
For non-z/OS platforms, use Chapter 2, "Installing and Configuring Oracle GoldenGate Monitor Agent".
For z/OS platforms, use Chapter 3, "Installing and Configuring Oracle GoldenGate Monitor Agent for z/OS".
Go to the Oracle GoldenGate Core GGSCI terminal and stop the Oracle GoldenGate Monitor Agent by executing the stop
jagent
command:
GGSCI>stop jagent
Verify that there are no remaining jagent
processes after by running the following command:
ps -ef |grep jagent
Use the kill -9
command to stop if any stray jagent
processes.
Copy the existing $Monitor_Server_Domain
/config/monitorserver/cfg
directory, including all content, to the new Agent directory, $AGENT_HOME
/cfg_templates
.
Use one of the following subsections to either create or upgrade your Monitor instance:
11g Upgrades: Creating a New Instance
Create a new instance using the instructions in one of the following dependent on your operating system:
For non-z/OS platforms, use Section 2.2.1, "Create the Instance."
For z/OS platforms, use Section 3.3.1, "Create the Instance."
This modifies the $OGG_HOME/dirprm/jagent.prm
file as in the following example:
COMMAND java -Dconfig.dir=/home/oracle/oggmon_agent/oggmon/cfg -Djava.util.logging.config.class=oracle.core.ojdl.logging.LoggingConfiguration -Doracle.core.ojdl.logging.config.file=/home/oracle/oggmon_ agent/oggmon/cfg/logging-config.xml -Doracle.core.ojdl.logging.componentId=JAGENT -jar -Xms512m -Xmx1024m /home/oracle/oggmon_agent/oggmon/ogg_agent/dirjar/jagent.jar
In this example, the jagent
that will now be used is in /home/oracle/oggmon_agent/oggmon/ogg_agent/dirjar/jagent.jar
and its configuration file is in the /home/oracle/oggmon_agent/oggmon/cfg
directory.
12c Upgrades: Upgrading the Existing Instance
Run the Monitor Agent upgrade utility by entering the following command:
Go to the $AGENT_HOME
directory. For example:
cd /u01/app/oracle/product/wls/oggmon/ogg_agent
Run the upgrade script:
For this Operating System | Use this command |
---|---|
Unix |
$ ./upgradeToMonitorAgent1221.sh |
Windows |
C:\ upgradeToMonitorAgent1221.bat |
The system responds:
Please enter absolute path of Oracle GoldenGate home directory:
Enter the absolute path to your Oracle GoldenGate home directory. For example, /u01/ogg/replication/oggcore1
.
The system responds:
Please enter absolute path of OGG Agent instance :
Enter the directory that contains your Oracle GoldenGate Monitor Agent instance, which can be an existing directory. For example, /u01/ogg/agents/oggmon/agent1
. This directory should be different than the Oracle GoldenGate home directory to avoid overwriting your Oracle GoldenGate Monitor Agent JAR and configuration files the next time you install or patch Oracle GoldenGate.
Note:
For Windows, you must ensure that you provide the absolute JDK8 directory path explicitly or the Monitor Agent cannot connect to the Monitor server. This directory path can also be defined in thejagent.prm
file.The Oracle GoldenGate Monitor Agent Instance directory can be an existing folder location. In that case, you are prompted:
OGG Agent instance directory already exists, do you want to overwrite the contents (yes | no)".
If you choose yes
, the execution of the script will continue and all the contents related to Oracle GoldenGate Monitor Agent will be overwritten on that location. If you choose no
, the execution of the script will stop.
The system responds:
Please enter unique name to replace timestamp in startMonitorAgent script.
Enter the unique name that you want to replace the timestamp in the startMonitorAgent.sh
script file.
Once the Monitor Agent upgrade completes successfully, the Monitor Agent wallet credentials are also updated.
Go to the Oracle GoldenGate Core GGSCI terminal and restart the Oracle GoldenGate Monitor Agent by executing the following commands:
stop manager
start manager
start jagent
Monitor the new Agent log file, $AGENT_HOME/logs/ogg_agent.log
and resolve any issues.
If you are using the Oracle GoldenGate EM Plug-in, after jagent
starts correctly you must restart the Oracle Enterprise Manager (OEM) Agent then login to the OEM 12c console to ensure that the out of sync status issues for Oracle GoldenGate registered targets are resolved.
Remove the previous Oracle GoldenGate Monitor Agent software that was bundled with Oracle GoldenGate Software by deleting the following:
OGG_HOME
/cfg
folder
OGG_HOME
/dirjar
folder
OGG_HOME
/pw_agent_util.*
files
OGG_HOME
/jagent.*
files
(Optional) If you do not store anything related to Oracle GoldenGate Instance in Oracle Wallet, then delete the OGG_HOME/dirwlt
directory.
