Environment

Operations Bridge Manager (OBM) 2021.05 and later
Operations Agent (OA) All Versions
Data Flow Probe (DFP) All Versions

Situation

Operations Bridge Manager (OBM) version 2021.05 | Build: 11.10.010.004, running on an infrastructure consisting of 2 Linux application servers and 4 Windows DFP probes.
There is the following directory on the sever:
C:\Program Files\Java\jre1.8.0_271\bin.

Is this Java component (jre1.8.0_271) provided as part of the OpenText products. If so, is it possible to replace it with a newer version or a different Java component?

Resolution

The path mentioned C:\Program Files\Java\jre1.8.0_271\bin is a client side installed JRE which is not used in OBM these days nor OBM depend on it. OBM does not use Java for its UI, only the uCMDB does, but it has it local client that comes with its own embedded Java binaries. So one can do whatever is prefered with this JRE. Uninstall it or install different version. In the end the modern browsers (Chrome, Mozilla even Edge) do not support JRE usage in it anymore. 

The Java that comes with the applications (server side Java JDK) is located for OBM under "\HPBSM\JRE" and for the Operations agent under "\Program Files\HP\HP BTO Software\java". This server side Java cannot be removed or replaced with newer versions by demand. So the path includes in the name "HP". That is how one can recognize that is a Java that comes installed with the application. For DFP the java is under "\UCMDB\DataFlowProbe\bin\jre". As a side node in latest OBMs we use now OpenJDK and Zulu not Oracle Java.
