The manager start hung:

./EMCtrl.sh status: Enterprise Manager stopped

By removing the JRE folder before the hotfix installation, the system java will be used (java version "1.8.0_281"), this is the reason the manager will start.
Based on the shipped java (openjdk version "1.8.0_292") it does not.

WebView process has the same issue

Environment

Release : 10.7.0

Component : Introscope

Cause

This was investigated actually as a limit in the data segment size ulimit -d based on the amount of data the JRE needs to address.

Resolution

ulimit -d was raised to minimum 524288 to allow the Enterprise Manager and WebView to start

If ulimit -d cannot be set to unlimited, a trial and error approach of testing the minimum required value may be necessary.
