Insight Installation problem with existing WAS6.1

Hi,

Insight v 1.0 instalation is failing with following messages.

WASX7246E: Cannot establish "SOAP" connection to host "afjazz02.watson.ibm.com" because of an authentication failure. Ensure that user and password are correct on the command line or in a properties file.
Exception message (if any): "ADMN0022E: Access is denied for the getProcessType operation on Server MBean because of insufficient or empty credentials."
WASX7213I: This scripting client is not connected to a server process; please refer to the log file /apps/WebSphere/WAS6.1/profiles/JazzSrv01/logs/wsadmin.traceout for additional information.
WASX8011W: AdminTask object is not available.
Setting up environment variables
WASX7017E: Exception received while running file "/apps/IBM/RationalInsight/reportal/contentstore/db2/C8SE_config_db2_linux_only.jacl"; exception information: com.ibm.ws.scripting.ScriptingException: WASX7070E: The configuration service is not availa

While analyzing the log, this failure is because my WAS installation has another profile which is default profile that is part of Deployment Manager. I could see a new profile RationalInsight created, but the reason to failure is that Insight installer is calling wsadmin.sh from $WAS_ROOT/bin without -profile option and getting connected to default profile. The problem with insight installer is that if it fails, then it needs to be restarted after cleaning up everything which is a time consuming process. Is there any way to change the behavior of calling wsadmin? Can anyone tell the place where I could go and make necessary modifications to the wsadmin scripts (JACL or Jython)?

Thanks in advance,
Rijesh.
