Websphere Portal 6.1.5 - portal light mode

WebSphere Portal now comes with something called "portal light mode". Once enabled, a set of portlet applications are not started during portal startup. it works on line of lazy loading wherin these portlet applications are started when portal recieves a first http request for the portlet.

wp.base_ProfileEarAttributesTargetMapInclList.jacl contains the list of portlet applications that has to be lazily loaded.

COMMAND TO ENABLE LIGHT MODE

WPS 6.1.5 installation issue: CreateProcess failed ==> %1 is not a valid Win32 application

I was trying to install WPS 6.1.5 on my windows XP and it was failing with following error:
CreateProcess failed ==> %1 is not a valid Win32 application

after some troubleshooting i could resolve this. It was happening because i had two user variables defined in windows environment variables as follows:
TEMP = %USERPROFILE%\Local Settings\Temp
TMP = %USERPROFILE%\Local Settings\Temp

with this install.bat was having problems with directory name having spaces.

I tried changing it to TEMP = c:\mytemp

at this time i started getting

CreateProcess failed ==> %1 is not a valid Win32 application

later i realised that there are two system variables defined as well with similar name TEMP and TMP as follows:

TEMP = c:\Windows\TEMP
TMP = c:\Windows\TEMP


so, i removed the uservariables TEMP and TMP and tried the installer once again and it installed successfuly. :)
