Command Central Cache Takes too Much Disk Space
In case you have to reduce the size of the Command Central cache, stored in the Software AG_directory /profiles/CCE/data/cache/persistence directory, you can change the default disk compaction strategy used by Command Central. By default, Command Central uses a compaction strategy that favors performance to disk storage requirements. However, when required, you can update the disk compaction policy to size-based, which favors predictable disk usage to performance.
To update the disk compaction policy, on the Command Central web user interface, navigate to Environments > ALL > Instances > CCE > Configuration > Java System Properties, click Edit, and add the following lines:
com.tc.frs.compactor.policy=SizeBasedCompactionPolicy
com.tc.frs.io.nio.segmentSize=104857600
com.tc.frs.compactor.sizeBased.threshold=0.50
com.tc.frs.compactor.sizeBased.amount=0.05
Note that the system has to work for some time after updating the disk compaction policy, before it starts reducing the cache. For more information about:
*The disk compaction properties, see Disk Compaction Strategy for the Command Central Cache.
*The FRS disk compaction policy, see the BigMemory Max documentation.
