Hi,
This issue most likely is related to a communication problem with the database or a corruption as we can see from the logs :
2010/11/21 19:44:41 main ani ERROR POStore: Failed resolving object because: java.lang.NullPointerException
2010/11/21 19:44:41 main ani ERROR AniMain: java.lang.NullPointerException
ANI Server failed to load from the database.
Please stop and restart the system. You may need to re-initialize the database.
If this does not work, please contact technical support.
The next step is to re-initialize the Campus Manager database. This procedure will delete all the records and maps that you have in Campus Manager, you would need to run a new Campus Data Collection and User Tracking Acquisition to have clean and fresh database information.
If that ok with you, you can try the below steps to re-initialize the Campus database. By doing this, it will not effect any other database of LMS will clean Campus Manager database.
+) Stop the daemon manager:
net stop crmdmgtd
+) cd CSCOpx\bin\
+) Type the following command (case sensitive):
perl dbRestoreOrig.pl dsn=ani dmprefix=ANI
+) Start the daemon manager:
net start crmdmgtd
Now, wait another 15 minutes and wait for dmgtd.lock file to release from location CSCOpx\objects\dmgtd\ready.
Now check the status of ANIServer with command :- pdshow ANIServer ( case sensitive)
it should have the status Busy with Flag set.
Thanks,
