When you save a modification in the Administration Console, the new configuration does not immediately apply to the running instance. Instead, it appears in the configuration store.
When you apply the configuration, it shifts to all running components. Exalead CloudView checks the high-level configuration for errors, then computes a low-level configuration for each process, known as the GCT.
You can find the configuration store in <DATADIR>/config. It contains the latest version of all configurations, stored as XML files.
To roll back to a previous configuration, you must:
1. From the top navigation bar of the Administration Console, click the down arrow next to Apply.
2. Select Rollback to version for the required version.
