Context

In BTT version 4.3, all the parameters for context are defined under <kColl id="context"> in des.ini, as shown in the following code sample:
<kColl id="contexts">
					<field id="context" value="com.ibm.dse.base.Context"/>
				</kColl>
After you migrate to BTT version 6.1.2, the definition of Context and CHA contains client side CHA and server side CHA in btt.xml.
Following is the code sample:

		<!-- Context is object defines and encapsulates a set of resources -->
