Hi,
I need to change my RAC database from nonarchive mode to archive mode.
I execute the following commands:
srvctl stop database -db racdb –shutdown
srvctl start database -db racdb mount
in sqlplus, I execute> alter database archivelog;
Now how to open the RAC from Mount to Open stage?
Is I shutdown and start again?
Alter database open
Showing following error
ERROR at line 1:
ORA-01157: cannot identify/lock data file 7 - see DBWR trace file
Please advice,
how to change the satus of rac db from mount to OPEN?
Where the archive file goes?
