Hi Wolfson,
 
9i RMAN can help you to clone the database using duplicate target database. It 
will take care of resetting the DBID too. Not sure this is what you are looking 
for. I have used a couple of times and it worked fine.
 
Best Regards

        Thanks for info Ken.
        
                Any idea on my original RMAN clones?

        The Oracle 8i install on Solaris does hard code some of the os path's 
into
        some of the binaries (particularly java related ones) and the database 
will
        work fine assuming everything is soft linked properly until you need to
        apply a patch or upgrade the system. T universal installer had issues 
even
        though the orainventory was identical to the other server. I had to 
install
        the software and only then I could apply patches. I haven't tried this 
with
        9i but IMHO I'd avoid it. I hear 10g will allow cloning of an 
installation
        onto the grid.

        I don't need RMAN, client is insisting on it.
        
                I thought the "RESETLOGS" just reset the redo counter.
        
                I'd swear we did that with another database and RMAN got all
        confused about what DBID the archives belonged to.
        
                And now that you mentioned it Mladen, can I take my 9i install, 
tar
        it up and copy it to another server?  Apply some soft links and do a 
relink
        all instead of multiple installs?
                This particular client has all SUN servers.
        
                Thanks

        Actually, why do you need rman? If you use the the cloning tool
        known as "cp" or "scp", if the clone needs to be on another node,
        you can get the desired result with a FS-based database. The DBID
        problem is solved by opening the database with the "RESETLOGS" option.
        Once you issue "alter database open resetlogs" command, your old
        DBID is gone and, technically speaking, you have a new database.
