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

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.
+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

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.
