Oracle Database Discussions

Oracle 11.2.0.1

We store our data on a NAS share - Data files, log files, temp files and the control file.

Is my the setup:

Host1 has database IMR1

Data Location: /du01/imr1

Host2 has database IMR1 (empty database, no application data)

Data Location: /du01/imr1/IMR1

I want database IMR1 on Host 2 to look like the database on Host 1.

In other words, both database should use the same file location - /du01/imr1.

Here is what I did.

Shutdown the database on Host 2.

Edited the parmeter file - changed the controlfile location to /du01/imr1/control01.ctl

Ran: create spfile from pfile='/u01/app/oracle/admin/IMR1/pfile/initIMR1.ora'

Then started up the database:  startup pfile=/u01/app/oracle/admin/IMR1/pfile/initIMR1.ora

But I get this error:

ORACLE instance started.

Is there something I'm missing or is there an easier way to do this?
