Per the PIM documentation, a separate Java install is required for PIM endpoints running on s390x Linux. Can that Java be upgraded to newer versions or does it have to stay at a particular version?
Privileged Identity Manager 12.8 SP1
As of PIM build 22.214.171.12416 (6/17/2021), the endpoint includes its own JDK for Java-related services. An external Java install is no longer required for newer endpoints, please upgrade to the newest build to take advantage of this functionality.
The latest PIM endpoint can be downloaded from the Broadcom Support link below.
