Issue: When upgrading Identity Manager to version 4.8.6 on a server running RHEL 8.5 or RHEL 8.6, OSP fails to start due to a database connection issue. It typically happens when the random key generation process takes longer than expected while the OSP is getting deployed. As a result, Tomcat services also fail to start. (Bug 569043)
Workaround: Modify the following lines in the java.security file at /opt/netiq/common/jre/lib/security/ location and restart Tomcat:
NOTE:Before applying the workaround, we recommend you read the RHEL documentation for more information on random number generators.
