Java Error Encountered When Running Identity Manager on IBM JVM

Products

• CA Identity Manager

Issue/Introduction

When executing workflows or initializing services within CA Identity Manager, the system fails and generates a critical Java exception error.

This issue specifically occurs because of a compatibility conflict inherent to the underlying runtime environment. The runtime environment crashes when running the application on an IBM Java Virtual Machine (JVM).

Environment

Release : 14.4 Identity Manager

                 Websphere Version - 8.5.5.22

                 Linux

                 

Cause

The JAVA selection in the installer is used by Administrative tools, not WebSphere 

Resolution

To resolve this issue and restore application stability, you must migrate the runtime environment from the IBM JVM to the OpenJDK platform.

Required Action:

Configure the Identity Manager application server instance to utilize OpenJDK instead of the IBM JVM.

1. Download and Install OpenJDK: Procure a supported version of OpenJDK that aligns with your specific CA Identity Suite deployment requirements.
2. Update Environment Variables: Modify your server configuration files (such as JAVA_HOME and PATH system variables) to point directly to the new OpenJDK installation directory.
3. Restart Services: Restart the application server instance to apply the changes and verify that the Java error no longer populates during standard execution.
