Data Express DXCOMMON environment variable

Problem: 

Data Express Oracle extension uses an internal text file called dxe_common.txt, which provides information between the separate parts of the execution chain. By default this file is created in the log directory and is deleted right before the end of the extension elaboration. When the user has specified a network share as a log output directory, the creation, writing and deletion of this file might decrease the performance.

Resolution:

As a solution, we implemented the usage of a new environment variable, called DXCOMMON.

Steps to implement the new feature:

1. Create a new environment variable, called DXCOMMON from Control panel --> System --> Advanced system settings --> Environment variable and set a folder name where you want to create the file dxe_common.txt. 

             Please remember to leave the path without a slash at the end!

      2.  Restart  the Windows system.

Notes:

1.  If the variable does not exist or its value is an empty string, the default log folder will be used as common file destination.

2.  If the specified folder does not exist, the Oracle extension will create it.
