DRAFT KB-XXXX Cannot run program "jps" error when starting Service Manager

Symptoms

When executing a Service Manager script in the <APPIAN_HOME>/services/bin directory, the following error is returned:

Exception thrown while attempting to retrieve process info for java process with main Class name QuorumPeerMain. java.io.IOException: Cannot run program "jps": error=2, No such file or directory
...
Caused by: java.io.IOException: error=2, No such file or directory

Cause

This error is returned when the JAVA_HOME path is set to JRE, rather than JDK. As per the Appian system requirements, JDK is the supported option.

To check the JAVA_HOME variable:

• In Windows, right click My Computer and select Properties. On the Advanced tab, select Environment Variables, and edit JAVA_HOME to view the JDK path.
• In Linux, type echo $JAVA_HOME in a terminal to view the Java path.

Action

To resolve the issue, follow the Appian documentation on setting up the JAVA_HOME and PATH variables to point to the JDK.

Affected Versions

This article applies to Appian 17.3 and later.
