Data Loss Prevention Enforce

Issue/Introduction

Data Loss Prevention Endpoint users (current or former) may not be able to upgrade from version 11.x to version 11.5 under certain circumstances.  

The upgrade process may not succeed if the total filepath for an Endpoint incident is more than 254 characters. Specifically, the Upgrader fails if there was an incident that involved a file for which the pathname plus the filename exceeds 254 characters (and the incident is stored in your database).

If your Upgrader fails because of this issue, the SQLError.log file is created.

Resolution

Before you upgrade, you can check whether incidents are generated with filepath and filenames larger than 254 characters.

Connect to the Enforce Server database using SQL*Plus and run the following query as the protect user:

SQL> select count(*) from message where length(ENDPOINTFILEPATH) > 254;

If the script returns count = 0, you are not affected by this issue. You can proceed with the upgrade.

If the script returns count = x where x is any value other than 0, your database contains Endpoint incidents with filepaths that are greater than 254 characters.

You must wait to upgrade until a new upgrader is available. Maintenance Pack (MP1) for version 11.5 is forthcoming from Symantec. You will need MP1 version 11.5 to upgrade if you have Endpoint filepaths greater than 254 characters.
