Issue/Introduction

Running Performance Management release r20.2 and need to know the correct locations Java is installed and runs from on the Performance Management servers.

What is the correct location for Java on Performance Management servers?

Environment

All supported Performance Management releases

Cause

Other tools or OS installed Oracle Java versions not related to PM are installed.

Resolution

While the versions of Java will change over time, generally the location we use to install and run it will remain the same.

The following information shows how to to determine:

  • Where are there Java versions are installed?
  • What are the various Java versions installed?
  • Is PM using a Java version outside of it's default? Which version is it using?

Any version on the system not utilized by the product can be removed.

NOTE: The following samples are from an r3.7.10 release of Performance Management.

Where is Java installed?

To determine this run "locate -r bin/java$".

Example of the output from each system in Performance Management.

Performance Center:

[root@PC_HOST ~]# locate -r bin/java$
/opt/CA/PerformanceCenter/jre/bin/java
/opt/CA/jre/bin/java
/usr/bin/java
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.212.b04-0.el7_6.x86_64/jre/bin/java
[root@PC_HOST ~]#

Data Aggregator (with or without FT configuration):

[root@DA_HOST ~]# locate -r bin/java$
/opt/IMDataAggregator/jre/bin/java
/usr/bin/java
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.212.b04-0.el7_6.x86_64/jre/bin/java
[root@DA_HOST ~]#

Proxy Host for FT DA configuration:

[root@ProxyHost ~]# locate -r bin/java$
/opt/CA/daproxy/jre/bin/java
/usr/bin/java
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.212.b04-0.el7_6.x86_64/jre/bin/java
[root@ProxyHost ~]#

Data Collector:

[root@DC_HOST ~]# locate -r bin/java$
/opt/CA/IMDataRepository_vertica9/jre/bin/java
/opt/IMDataCollector/jre/bin/java
/usr/bin/java
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.212.b04-0.el7_6.x86_64/jre/bin/java
[root@DC_HOST ~]#

Data Repository:

[root@DR_HOST ~]# locate -r bin/java$
/opt/CA/IMDataRepository_vertica9/jre/bin/java
/usr/bin/java
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.181-7.b13.el7.x86_64/bin/java
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.181-7.b13.el7.x86_64/jre/bin/java
[root@DR_HOST ~]#

What Java versions are installed?

For any bin/java$ file found we should be able to run the following and see the specific version it represents. Run this for each one present on the server.

<PATH>/bin/java -version

Using the above Performance Center output as an example we can see that per the output results it has both Java 1.8.0_222 and Java version 1.8.0_222 present.

[root@PC_HOST ~]# /opt/CA/PerformanceCenter/jre/bin/java -version
openjdk version "1.8.0_222"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_222-b10)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.222-b10, mixed mode)

[root@PC_HOST ~]# /opt/CA/jre/bin/java -version
openjdk version "1.8.0_222"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_222-b10)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.222-b10, mixed mode)

[root@PC_HOST ~]# /usr/bin/java -version
openjdk version "1.8.0_212"
OpenJDK Runtime Environment (build 1.8.0_212-b04)
OpenJDK 64-Bit Server VM (build 25.212-b04, mixed mode)

[root@PC_HOST ~]# /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.212.b04-0.el7_6.x86_64/jre/bin/java -version
openjdk version "1.8.0_212"
OpenJDK Runtime Environment (build 1.8.0_212-b04)
OpenJDK 64-Bit Server VM (build 25.212-b04, mixed mode)

Which Java version is in use by Performance Management system services?

Run the following command to determine the answer to this:

ps -ef | grep bin/java

Here we see sample output, again from Performance Center. We can see where the command indicates it's running out of the /opt/CA/jre/bin/java directory, one installed and owned by the product.

[root@PC_HOST ~]# ps -ef | grep bin/java

Additional Information

As of release r3.7.3 we no longer install or utilize Oracle Java versions. We only use OpenJDK Open Source based Java releases.
