DLP 16.0.1 on RHEL 8.2
Symlinks for DLP services were missing in the /etc/rc.d/init.d directory
1. Created the symlink for the Enforce services by running below command:
ln -sf /opt/Symantec/DataLossPrevention/EnforceServer/Services/SymantecDLPNotifier.sh /etc/rc.d/init.d/SymantecDLPNotifierService
ln -sf /opt/Symantec/DataLossPrevention/EnforceServer/Services/SymantecDLPManager.sh /etc/rc.d/init.d/SymantecDLPManagerService
ln -sf /opt/Symantec/DataLossPrevention/EnforceServer/Services/SymantecDLPIncidentPersister.sh /etc/rc.d/init.d/SymantecDLPIncidentPersisterService
ln -sf /opt/Symantec/DataLossPrevention/EnforceServer/Services/SymantecDLPDetectionServerController.sh /etc/rc.d/init.d/SymantecDLPDetectionServerControllerService
2. Then started Enforce services by running below command and they started successfully:
systemctl start SymantecDLPDetectionServerControllerService
systemctl start SymantecDLPIncidentPersisterService
systemctl start SymantecDLPManagerService
systemctl start SymantecDLPNotifierService
