Resolution:
"DataManager.Directory" is the engine tra file property which dictates where checkpointed jobs need to be written.

The solution to this problem is to make use of a new feature "Custom Engine Properties". Here are the steps to include "DataManager.Directory" as part of the deployment ear file. Here are the steps :

-go to &ltBW-HOME>\lib\com\tibco\deployment, edit the file 'bwengine.xml'
-add the following...
&ltproperty>
&ltname&gtDatamanager Location</name>
&ltoption&gtDataManager.Directory</option>
&ltdefault&gtc:\temp</default>
&ltdescription&gtDatamanager location</description>
</property>


After doing the above change,open designer & create ear file
-load ear file into Admin.
-you should see the variable 'DataManager.Directory' under Configuration/process-archive/advanced
-modify the location of "default" value as per your requirements

NOTE :-On every machine where BW process Archive files are going to be created the above change to the "bwengine.xml" needs to be done.
