New Command for Tungsten: tungsten_get_status

Tungsten Clustering contains many tools to monitor your cluster, and today we will look at a new one - the `tungsten_get_status` command, included with Tungsten versions 6.1.19+ and 7.0.2+. This tool was created in response to a customer request for a simple script that could display the status of all nodes cluster-wide for any topology from a single place. The status includes the datasource and replicator layers along with the policy for each cluster.

Tungsten Replicator: New Pause and Resume Feature in v7.0.2

Tungsten Replicator is a powerful tool with many great features, and today we will look at a new one - the ability to Pause and Resume a replication service. Until now, the only way to stop a replication stream was to take the service offline, and put it back online when it is needed again. The online process involves a number of internal steps and overhead, and if there are many THL files on disk, it could take some time to index them all before the service can come fully online. To remove the overhead of the startup time, the new pause/resume feature was developed for the Replicator, and is accessed via the `trepctl` command.
