Data360 Analyze: how to store executions data on another disk on Windows Server

Analyze only sees the directory structure on a Linux or Windows server. It does not see local or external disks, so they need to be mounted.

PRE-REQUISITE STEPS:

** It is recommend that you take a Windows system level backup before mounting a disk

** Ensure the permissions on the new mount point are the same as those on the existing executions folder - else the Analyze user (and hence the Analyze software) won't be able to perform read, write or execute operations on the new mount point.

** Ensure that you choose a location with sufficient space, as the temporary file directory can become very large over time.

BACKGROUND:

By default, temporary files are stored in the following location:

<Data360Analyze data directory>/data-<port number>/executions

e.g. C:\Users\<username>\Data360Analyze\data-7731\executions

Existing temp data is not copied automatically over to the new location from the old one. 

STEPS:

1. At the required point in the filesystem, create the directory that is to hold the temp data. For example, on "D:\ drive", create a folder called "Server_mount" and a subfolder called "executions"

2. Mount the newly created point

3.  Shut down Analyze, see here for instructions

4. If you wish to retain the existing temp data from the default location, then copy over the data to the new one. Otherwise this step can be skipped. 

5.  Navigate to your cust.prop file under <Data360Analyze_DataDir>\Data360Analyze\site-                   7731\conf

6. Open the cust.prop file and add the following text on a new line, replacing <temp directory> with      the file path of the location where you want to store temporary files:

ls.brain.tempDir="<temp directory>"

Example:  ls.brain.tempDir="D:/Server_mount/executions"

Please note: the double quotes surrounding the entire path are required

Please note:  forward slashes are required in the path

7. Restart Analyze for the changes to take effect, and re-run some nodes
8. Once you've verified that the temp data is being written to the new location, you can delete the old executions folder if you wish
