RE: RMAN giving error ORA-19550

Mercadante, Thomas F





Are you running Rman on the database server itself?  If so, just set the ORACLE_SID and connect without using the “@qa1” option.

Secondly, you can always set up a second entry in your tnsnames.ora file for the database and make it a dedicated connection.  Then use that connection for Rman.


rman target sys/abc@qa1_dedicated nocatalog



Qa1_dedicated = 



      (ADDRESS = (PROTOCOL = TCP)(HOST = xxxxxxxx)(PORT = 1521))



      (SID = qa1)





Good Luck!

Subject: RMAN giving error ORA-19550




We are using Shared server and when  trying to do rman backup getting error:

ORA-19550: cannot use backup/restore functions while using dispatcher


I modified the tnsnames.ora to add the following clause:

(server = dedicated)


But now getting the error:

C:\backup\Personal\OracleScripts>rman target sys/abc@qa1 nocatalog
