Move Database from DATA to RECO ASM Disk Group On Exadata

Exadata Database machine consists of 3 ASM Disk Groups:
+DATA for Database Files
+RECO for Online Redo log and Archive log files
+DBFS_DG for Cluster configuration files such as OCR and Voting disks

In a Customized environment Customers can choose to have more than 3 Disk Groups. But it is recommended to have 3 Disk Groups. The DATA and RECO disk groups can be sized 80%-20% or 40%-60% respectively of over all storage capacity. Sometimes it is possible that +DATA disk group can be filled very fast if you have several databases.

In this article we will demostrate how to move a Database from +DATA disk group to +RECO disk group.


Steps to move a database from +DATA to +RECO ASM Disk Group:


Step 1: Get the ASM Disk Information

SQL> select state,name from v$asm_diskgroup;

STATE       NAME
----------- ------------------------------
MOUNTED     RECO
MOUNTED     DBFS_DG
MOUNTED     DATA


Step 2: Get the Database files details

SQL> select name, open_mode,database_role from gv$database;

NAME      OPEN_MODE            DATABASE_ROLE
--------- -------------------- ----------------
DBM01     READ WRITE           PRIMARY
DBM01     READ WRITE           PRIMARY
DBM01     READ WRITE           PRIMARY
DBM01     READ WRITE           PRIMARY

SQL> select name from v$controlfile;

NAME
--------------------------------------------------------------------------------
+DATA/dbm01/controlfile/current.256.976374731

SQL> select name from v$datafile;

NAME

7 rows selected.

SQL> select name from v$tempfile;

SQL> select member from v$logfile;

SQL> select filename from v$block_change_tracking;

Step 3: Backup Database using RMAN copy command as shown below. Here we are moving database to +RECO ASM Disk Group.

Conclusion

In this article we have learned how to move a Database from +DATA ASM Disk Group to +RECO Disk Group. Using RMAN along with FRA makes it easy to move a database from one location to another.
