RMAN connection error

Li Li


Hi, All,
I was trying to clone my production RAC database to my test box. When I tried to RMAN connect to my production db from my test box (which has the exact same oracle version) and I got the following error, it looked like it cannot access the target host. However I was able to connect to my production db through SQL/PLUS.
Any idea what would be the problem?

[oracle@rac_node1 ~]$ $ORACLE_HOME/bin/rman target sys/xxxx@proddb auxiliary /
