Error in Step create-ear-metrics - Connections 4 upgrade

- installation

Had a hard time last week with a Connections 4 upgrade.

Whenever I tried to install the Connections apps (on a fresh WAS install!) I got an error during metrics ear file creation:

java.lang.NoSuchFieldError: com/ibm/datatools/internal/core/util/EngineeringOptionID.GLOBAL_VARIABLE

Googling brought me to this technote:

So I had to delete some WAS files and everything worked after that!?

 

PS: I assume that a failed Fixpack installation at the beginning (of course fixed and reinstalled later on) was the source of the problem
