  Sorry, the mail system mangled my message. It's all there, just part is below the signature. Here it is again:

I think that is about the performance we get. Maybe faster than what we get.

   One idea would be to copy some big files using file system commands like "cp" and see what the performance is. My guess is that would be your theoretical upper limit.

Anybady have values of how many GIGS per HOUR they can Backup and RESTORE the database
using RMAN backup to disk.  

What kind of machine, Memory, storage?  

  1. I am using cheap network attached disk
  2. I am getting about 40 Gigs an hour for Backup
  3. I am getting about 34 Gigs an hour for Restore
  4. 350 Meg of SGA on an Hp9000

Anybody find a good way to improve performance other than increasing channels?  

Cheers,
Thanks for any help

Anjan,  

Kind of strange there is no lib32 dir under your $ORACLE_HOME. Hummm.... try setting the following on the user's .profile or on your user's shell startup file:  

LD_LIBRARY_PATH = $ORACLE_HOME/lib

LD_LIBRARY_PATH_64 = $ORACLE_HOME/lib  

Maybe oracle is looking for 64 bit library files!

Gurus,  

Would appreciate any help that I can get on this...  

I have 9.2.0.1 on redhat 9 ...  

However I cannot seen to start the agent on the server...  

agentctl start just bails out.. no messages...  

This what I see in the dbsnmp.nohup  

/db/app/oracle/product/9.2.0/bin/dbsnmp: error while loading shared libraries: libvppdc.so: cannot open shared object file: No such file or directory
Agent exited at Wed Aug 20 12:33:26 CDT 2003 with return value 127 Agent thrashing. Exiting dbsnmpwd at Wed Aug 20 12:33:26 CDT 2003  

libvppdc.so file exists in the location ORACLE_HOME/lib and it is a 32 bit file..    

Thanks in advance...  

Anjan
