Scenario 1

Symptom: When attempting to start Partner Hub, the following message appeared on the screen:

image:HubStartErrorClip.jpg

Solution

The solution is to run UpdateCentralHub from the Master Install Applauncher, which can be done by following the instructions from Scenario 1 of Can't get checksum for shared package!

Discussion

This was one of several error messages on a hub that would not start. The file PartnerHub\CentralHub\os\windows\jre\lib\i386\jvm.cfg did not exist in this case. It did exist in the same path of the Master Install.

Other errors appearing in the same log:

Java.sql.SQLException: Communication link failure: java.io.EOFException, underlying cause: null

Discussion

This was one of several error messages on a hub that would not start. This particular error seems to be related to the SEDCSocket interface, but alone it does not seem to be the root cause of why the Partner Hub crashed. It appears that the error Could not open `PartnerHub\CentralHub\os\windows\jre\lib\i386\jvm.cfg was the primary reason why the Partner Hub crashed.
