Issue/Introduction
After installing UIM 20.3.3 in Redhat 8 with Oracle DB, when I restart the primary hub or OC the service nimbus doesn't start automatically.
Manually executing "systemctl start nimbus" doesn't work either.
Executing: systemctl status nimbus
return next
● nimbus.service - LSB: NimBUS Robot

Environment
Release : DX UIM 20.4*/23.4*
Component : UIM - ROBOT
Cause
The line 45 of /etc/rc.d/init.d/nimbus contains next:
./nimbus /opt/nimsoft
so the permissions denied problem occurs when executing the line that start the service.
The reason behind this error is that SELINUX is enabled.
After installation, CA UIM cannot function correctly in SELinux Enforcing mode until you add the CA UIM shared libraries to the safe list, or disable the SELinux
Resolution
Security-Enhanced Linux (SELinux) is a Linux feature that supports access control security policies.
While shutting down SELinux before installing UIM Server is not always necessary, doing so maximizes your chance for a successful installation.
If SELinux status is enabled, a Current mode of permissive is acceptable.
Disabling SELinux entirely is an even safer approach.
If you must run UIM Server in SELinux Enforcing mode, add the CA UIM shared libraries to a safe list. After you install CA UIM, execute:
chcon -f -t textrel_shlib_t /<UIM_install>/hub/libldapssl.so.0
chcon -f -t textrel_shlib_t /<UIM_install>/hub/libldapsdk.so.0
chcon -f -t textrel_shlib_t /<UIM_install>/hub/libldapx.so.0
<UIM_install> is the directory where CA UIM is installed.
