We have RAC One Node installed on a 4 node linux RHEL5 cluster. We do
not use Grid Control, but I've been using EM Database Control to manage
it.
The database I created is DBA1 and the instance running on the system
where I installed the RAC One Node rdbms was DBA1_1. I was able to bring
up a web browser on my PC and connect to DB control on the node where the
database was running and whatever I needed to with the database. That all
makes sense to me and everything seemed to be working fine.
Then I decided to relocate the database, using DB control. That also
seemed to work fine. The instance is now running on a different node and
is called DBA1_2. However, when I try to use DB control, it can't connect
to the database...TNS errors that the listener doesn't know about the
database. The instance it's trying to connect to is still DBA1_1, though.
I've read Metalink Document 1335697.1, but I get errors when I run the
emca commands.
So, I figured that I could just relocate the database back to the original
node and it would be back to where I started. Since I can't use DB control
to do that, I used crs_relocate. The database relocated back to the original
node just fine, except that the instance is still DBA1_2 and I still can't
use DB control because DB control is still trying to connect to DBA1_1.
I have a ticket open with Oracle, but I'm wondering if anyone else has run
into a similar issue. I'm pretty sure that I need to do something so that
DB control knows that the instance is now DBA1_2.
This is just a test system, and I'm still reading through the documentation
for RAC, etc. I'm sure there's some detail I missed somewhere, but haven't
yet found.
Any suggestions?
