Java.sql.SQLException: ORA-01157: cannot identify/lock data file 7 - see DB

Question

I am deploying my application components on Oracle RAC database, when i install my app component i will run a script which creates a user and tablespace on bot rac-nodes(node1 and node2)
as database is clustered, the user are created on 2 nodes and tablespace is stored in a shared location for two rac nodes
i am able to successfully run my script on rac-node1 and and installed my component and when i started installing the app component on node2 getting error
java.sql.SQLException: ORA-01157: cannot identify/lock data file 7 - see DBWR trace file
ORA-01110: data file 7: '/db/db/db/ora10g/10.2.0/admin/dbadmin_01.dbf'
ORA-06512: at "ADMIN.XL_SP_DBCHECK", line 48
ORA-06512: at line 1
"dbadmin_01.dbf is the custom tablespace which created by me"
i a mgetting error while installing the app component on rac-node2

Answer 1

You should not create database files outside of the ASM.
I'm not sure you can move the datafile, I would export the data from the tablespace (if there is data you need there), delete the tablespace and recreate it in the ASM, then import the data back.
If you want to move the datafile, you can try using RMAN (from node1).
First connect to the database with sqlplus and execute:
alter tablespace <tbs_name> offline;Then start RMAN: rman target /
BACKUP AS COPY DATAFILE '<file>' FORMAT '+<ASM_DG>';Then in sqlplus, execute:
alter tablespace <tbs_name> online;I'm not sure it will work, and I hope I got the commands right because I can't check it right now.
Good luck
