Method to Change Tablespace from Offline Immediate to Online After Recovery

Document Type | Technical Information

Category | Backup/Recovery

Applicable Product Version | 7FS02PS

Document Number | TBATI018

 

Overview

This is a scenario for changing a tablespace from offline immediate state to online after recovery.
 

OFFLINE NORMAL

The tablespace is changed to offline state after performing a checkpoint on it. When switching back to online state, no separate recovery process is required. If neither NORMAL nor IMMEDIATE options are specified, NORMAL is the default operation mode.
 

OFFLINE IMMEDIATE

Unlike NORMAL, the tablespace is changed to offline state immediately without performing a checkpoint, so media recovery must be done before switching back to online state.
 
 

Method

If the tablespace is in offline immediate state, use the automatic tablespace command.
 
1. Create tablespace and change to offline immediate
SQL>  create tablespace test01 datafile 'test_001.dtf' size 10M autoextend on next 10M maxsize unlimited;

Tablespace 'TEST01' created.


SQL> alter tablespace test01 offline immedate;


Tablespace 'TEST01' altered.

SQL> select * from v$datafile;
