Teamwork Cloud (TWCloud) is equipped with Data Manager for an administrative process. You need to download the data manager zip file and extract it to the machine where you installed Cassandra. Before using Data Manager, we recommend that you backup your database in the same manner as you do before using the migration tool. You can download the DataManager tool from the same location you download the migration tools for the Cassandra database and UML meta-model.
To run Data Manager
Stop the TWCloud server.
Make sure Cassandra is up and running.
Download DataManager.zip.
Extract the zip file to the machine where you installed Cassandra.
On the command line, change directory to DataManager folder. Type the command, datamanager -help, to display available commands like the following.
$ datamanager -help
Once you finish working with DataManager, type exit to close it, such as:
osgi> exit
Once Data Manager closes, run a major compaction on the esi keyspace using the nodetool utility.
$ nodetool compact esi
