Explanation
The two ClusterXL Deployment options are Distributed and Full High Availability. Distributed deployment means that each cluster member has its own Security Management Server and synchronizes with other members. Full High Availability deployment means that one cluster member is active and handles all traffic, while the other members are in standby mode and ready to take over in case of a failure. The other options are not valid ClusterXL Deployment options, but rather ClusterXL Modes or ClusterXL Load Sharing Methods.

The log server sends logs to the Correlation Unit. The Correlation Unit analyzes the logs and generates events based on the event policy. The events are then sent to the SmartEvent Server, which displays them in the SmartEvent GUI. Reference: [SmartEvent Administration Guide]

Explanation
The only way to make objects locked for editing available for other administrators is to publish or discard the session that contains the changes. Publishing the session will save and share the changes with other administrators, while discarding the session will undo and discard the changes. Saving the session will only save the changes locally, but not share them with others or release the locks. Reverting the session will restore a previous version of the session, but not affect the locks. Saving and installing the policy will only install the policy on the gateways, but not share or discard the changes in SmartConsole. Deleting older versions of database will only free up disk space, but not affect the locks.
