Automatic TSPITR in 10G RMAN 19C DBV expdp “TEST” RAC中 thread

TSPITR 注意事项：

19C DBV expdp 不用exp imp

“TEST” 一定要“” 起来，否则说找不到test tablespace.

RAC中 thread 要指定对，否则过度恢复。

SEQUENCE# 是drop 时的，不是创建时的。

tablespace 默认是offline的，要online， 10G不知道是不是自动的！！

-----------------Automatic TSPITR in 10G RMAN -A walk Through (Doc ID 335851.1)

For the purposes of this document, the following fictitious environment is used as an example to describe the procedure:

Database Name: PROD
Tablespace Name: TEST
Table Name: TEST001
Directory Location: D:\BACKUP\

SCOPE

RMAN automatic Tablespace Point-In-Time Recovery (TSPITR) enables you to quickly recover one or more tablespaces in an Oracle database to an earlier time, without affecting the state of the rest of the tablespaces and other objects in the database.

DETAILS

When performing fully automated TSPITR, letting RMAN manage the entire process. There are only two requirements which we need to specify manually.

1. Auxiliary destination for RMAN to use for the auxiliary set datafiles and other files for the auxiliary instance.

2. Configure any channels required for the TSPITR on the target instance.

    Note: The auxiliary instance will use the same channel configuration as the target instance when performing the TSPITR.

3. Use TS_PITR_CHECK view for identifying and resolving dependencies within the recovery set tablespaces.
    Refer to:
  RMAN Tablespace Point-in-Time Recovery (TSPITR)

Case Studies

The following case studies give the audience detailed steps in building a test environment and in practicing the procedure.

Setting up the environment:

1. Created a tablespace test and a table in that tablespace

SQL> CREATE TABLESPACE TEST DATAFILE 'D:\BACKUP\TEST.DBF' size 2 M;

SQL> CREATE TABLE TEST001 (id number) TABLESPACE TEST;

SQL> INSERT INTO TEST001 VALUES(100);
1 row created.

SQL> COMMIT;

SQL> SELECT * FROM TEST001;
ID
----------
100

2. Checked the CURRENT LOG Sequence

SQL> SELECT SEQUENCE# FROM V$LOG WHERE STATUS='CURRENT';
SEQUENCE#
----------
135

Sequence# 135 is my current log sequence 3. Take a backup of the database and current controlfile using RMAN.

4. Do a few log switches and drop the table.

SQL> DROP TABLE TEST001;
SQL> SELECT SEQUENCE# FROM V$LOG
WHERE STATUS='CURRENT';
SEQUENCE
----------
139

Table was dropped in log sequence 139. So TSPITR until log sequence 138 will give the table back.

Note: UNTIL TIME TSPITR syntax is :

RMAN> recover tablespace "TEST" until time "23-SEP-2005 10:00:00','DD-MON-YYYY HH24:MI:SS" auxiliary destination 'D:\Backup\temp';

True test starts

1. Connect to RMAN

C:> rman target / catalog <catalog schema>/<password>

2. Now run TSPITR until log sequence 138. Auxiliary destination is D:\Backup\temp.

RMAN> RECOVER TABLESPACE "TEST" UNTIL LOGSEQ 138 THREAD 1 AUXILIARY DESTINATION 'D:\Backup\temp';
