I have seen RMANs backup with no porblems them when it comes to restoration its no go.   Always test your RMAN restores.

 

When I have seen this behaviour its been related to hostname resolution.  RMANs are very sensitive to name resolution.  Go through all the documented tests to ensure reverse lookup and all the names match.   Also be careful about aliases in the hosts file, sometime they can cause side effects and mess up your restore attempts

Hello Chris

Have some experience with D/R of databases

Have you put No.Restrictions under altnames on your D/R master ?

The bprd or the dbclient maybe shed some light on the issue

Also CLIENT_READ_TIMEOUT and CLIENT_CONNECT_TIMEOUT might be worth to
look in to

Any entries in /var/adm/messages ?

Regards
Michael
