Looks like a memory issue to me too.  Run DBCC MEMORYSTATUS then see http://support.microsoft.com/default.aspx?scid=kb;en-us;271624.  This will help explain what you are seeing.

It looks to me that your server (node) ran out of memory.  The reboot frees up the memory temporarily, but I'd check out the RAM on your cluster.  You may...

I thought this was interesting because the same thing happened to me.  The error was a bit different: 

Attempt to fetch logical page (1:4358712) in database 'dbname' belongs to...

If that doesn't help, think about downgrading the Oracle driver to version 8.  The 9i driver still caused issues on our second server too.... the Cluster nodes are on Windows 2003 and so...

Sounds familiar.  We had Oracle 9i driver on a cluster and had to move it due to heavy usage of the linked server.  Even with a -g startup paramenter (to...

The secondary needs to be Enterprise or Developer edition.  See http://support.microsoft.com/default.aspx?scid=kb;en-us;314515

I use this.  Just put in the node names.

select hostname from sysprocesses

where hostname in ('node1','node2')

Did the procedure work before you upgraded to service pack 4?  Can you do a select successfully?  What ODBC driver are you using to connect to your AS400?  Have you...

I agree that it's not necessary to take the node offline once you have moved the group to the other node.  We have an active / passive setup, but the steps are...

Are you using linked servers heavily?  If so, you can add the -g startup parameter to increase memory in the virtual address space.  See BOL "Using Startup Options".

We've been replicating to Oracle for years.  All you need to do is install the Oracle client (or just ODBC, OLE DB) on the server and set up an ODBC...

Due to company policy all of our servers have an anti-virus software program running on all files and folders.  The only time I've seen an issue on a database server...

Be sure to take note that Distributed Transaction Coordinator needs to be installed as a Cluster Resource.  We've had 2 clusters built and both times the server group missed this part 🙂

Are the transaction logs restoring, or is the restore job still trying to execute?  If the job is still trying to run, you could try stopping & restarting it, or stop...

How about using just a restore with replace and move?  Run sp_helpdb TrainingDb to get the logical names and paths of the database you want to restore.  You may need to add a step...
