IBM Connections 3 - SCHD0063E: A task with ID 1 failed to run on Scheduler CommunitiesScheduler

Oops, having followed my previous posts, and moved from a Medium to a Small Deployment for IBM Connections 3, I then hit the following errors, seen in SystemOut.log, when starting my new small single-server cluster: -

Thankfully, this old-but-useful Technote came to my aid: -


In essence, I needed to clean up the databases ( for the Search Scheduler task ) and then refresh the Search task.

I started by stopping (!) my cluster, and then running the clearScheduler SQL script against some of the databases ( note that not all appear to have this option ): -

$ su - db2inst1
$ cd  /tmp/Wizards/Wizards/connections.sql

Activites

$ db2 -td@ -vf activities/db2/clearScheduler.sql 

Communities

$ db2 -td@ -vf communities/db2/clearScheduler.sql 

Files

$ db2 -td@ -vf files/db2/clearScheduler.sql 

Forums

$ db2 -td@ -vf forum/db2/clearScheduler.sql 

Homepage

$ db2 -tvf homepage/db2/clearScheduler.sql 

Profiles

$ db2 -tvf profiles/db2/clearScheduler.sql 

Wikis

$ db2 -td@ -vf wikis/db2/clearScheduler.sql 

before restarting the cluster 

I then jumped across to a completely different source of information, one that's more up-to-date: -


cd /opt/IBM/WebSphere/AppServer/profiles/Dmgr01/bin
$ ./wsadmin.sh -lang jython

wsadmin> execfile("connectionsConfig.py")
wsadmin> Scheduler.listAllTasks()
wsadmin> Scheduler.clearAllTasks()

and then restarted the cluster.

This time around, I get NO nasty scheduling errors.

Therefore, I'm not 100% sure that I actually needed to run the clearSchedule SQL script but it doesn't appear to have hurt :-)
