Steps mentioned in this article are taken from VMware's KB article: 87097 . The only difference is that this blog has screenshots which would be helpful while implementing the patch
I've documented these steps with screenshots and outputs in this PDF too. Click to download and see detailed outputs which would be available when workaround is implemented
NOTE:
If you have deployed vRSLCM on earlier releases of 8.x that's 8.0 or 8.1 then there is a chance that we have a left over file with the name " vmlcm-service-8.1.x-SNAPSHOT.jar " or " vmlcm-service-8.0.x-SNAPSHOT.jar " then the workaround will fail with the message " vRSLCM services jar does not exist "
To fix this issue , move this old file to a different location and then execute the script
The structure of the folder would always be like below. The one vmlcm-service-8.6.0-SNAPSHOT.jar indicates that this is the current file the service uses. It has version indicator too.
Remember , the workaround works only for version vRSLCM 8.2 onwards....
