Hi All,

I'm getting the following message in alert log for every 1 hour,

The host database is Oracle 10g and the db link GXN.WORLD connects to DB2 database.
Can anyone explain me what is happening in my database?What I've to do to resolve this problem so that the
following message will not appear in alert log?

Thanks...
