Description

To improve processing efficiency, system administrators can configure Clearwell to store cached data in another location either on or off the appliance. This storage solution provides the flexibility and capacity for larger document caches.  Relocating cache can be used as a method for reducing interruptions that can occur between cases when appliance storage caching is in progress. (This feature applies to the appliance as a whole. Clearwell does not support moving cached data at the case level.)

Solution:

1.  Backup the Clearwell appliance before moving cached data off the appliance.
2.  Click Support Features from System view
3.  From the Choose a support feature drop-down list, select Property Browser.
4.  Choose an appliance where you want to move cached data.
5.  For selecting the case (or system), select System. (Moving cached data applies to the appliance only.)
6.  For name of property to change, type:   esa.cluster.externalBaseDir
7.  To return to default settings for cached data on the appliance, leave the New value field blank. (This removes the property in order to revert to the default location on the local appliance.)
8.  To move cached data off the Clearwell appliance, for the New value field, type the UNC path: \\[sharename]
9.  Select the Confirm change. Are you sure? option.
10. Click Submit.

Note: The new value will not be used by the appliance until services are restarted.

11. Stop services on the appliance.
12. Move the existing local extdata and exttemp directories to the new external path
     a. Move   /extdata/ to   /extdata/
     b. Move    /scratch/exttemp/  to  /scratch/exttemp/

Note: For a typical environment, there will only be one "esadb" directory for
. It is generally safe to move the entire "extdata"  directory
to the external location. The target location is expected to be empty when performing the
cache relocation.

13. Restart services on the appliance, then log on to Clearwell.

Note: In a cluster, the above steps should be performed for each appliance in the cluster. Each
appliance must use a distinct value for the external directory. If the appliances are going to
share the same device, they should each be configured to write into a different subdirectory on
the device.
