So far, there are 2 archives in the table TEST of the user, ie 1 and 2.

There is also an unsubmitted in REDO, ie 3;

Now you are hot in the new window (SQLUS Internal), the current Archive log is 2777,

Note that the Archive log after the hot standby is observed, and record it to control the data reply.

Group 2 '/u01/oracle/backup2/redo02.log' size 500K,

#Control_files = ("/u01/oracle/backup2/controlfile01.ctl")

Control_files = ("/u01/oracle/backup2/control01.ctl")

It has been proven that if you don't do this, you will make an error below:

14, open the database with Open ResetLogs

This step has established the Redo Log file specified in Initnew.ora and opens the database.

SQL> ALTER DATABASE OPEN RESETLOGS;

Fifteen, verify that the data is restored

For convenience, you can open a session (window),

And set Oracle_SID = SCEDB; Export Oracle_sid

Then open the old database, and the new database is compared.

In the window (old database):

Oracle @ SCE> Oracle_SID = SCEDB; Export Oracle_sid

Oracle @ SCE> Env | GREP ORACLE

Oracle_base = / u01 / oracle

Oracle_home = / u01 / oracle / orahome1

Oracle_sid = SCEDB

In the window 2 (new database):

SQL> Conn Lunar / Lunar

Connected.

SQL> SELECT *.

Verified the database except for Redo's no reply, all of the files that archived

(Refer to the initial assumption:

So far, there are 2 archives in the table TEST of the user, ie 1 and 2.

There is also an unsubmitted in REDO, ie 3;

Now you are hot in the new window (SQLUS Internal), the current Archive log is 2777,

Note that the Archive log after the hot standby is observed, and record it to control the data reply.

)

Conclusion: This thermal backup is backup for valid database

First, the two databases are now DOWN, one side space or resources are not enough, then do the following:

Ten, edit the tracking file, save it as a SQL script (ready to create a trace file for new database)

Pay attention to 3 places:

(1). SET DATABASE "New2" Resetlogs

(2). Logfile

Group 1 '/u01/oracle/backup2/redo01.log' size 500K,

Group 2 '/u01/oracle/backup2/redo02.log' size 500k,

Group 3 '/u01/oracle/backup2/redo03.log' size 500K

(3). DataFile

'/u01/oracle/backup2/system01.dbf',

'/u01/oracle/backup2/tools01.dbf',

'/u01/oracle/backup2/rbs01.dbf',

'/u01/oracle/backup2/temp01.dbf',

'/u01/oracle/backup2/Users01.dbf',

'/u01/oracle/backup2/indx01.dbf',

'/u01/oracle/backup2/drsys01.dbf',

'/u01/oracle/backup2/lunar01.dbf'

The script for creating a new control file is as follows:

Create ControlFile Set Database "New2" ResetLogs ArchiveLog

MaxLogfiles 32

MaxLogmembers 2

MaxDatafiles 254

MaxInstances 8

MaxLoghistory 3630

Logfile

Group 1 '/u01/oracle/backup2/redo01.log' size 500K,

Group 2 '/u01/oracle/backup2/redo02.log' size 500k,

Group 3 '/u01/oracle/backup2/redo03.log' size 500K

DataFile

'/u01/oracle/backup2/system01.dbf',

'/u01/oracle/backup2/tools01.dbf',

'/u01/oracle/backup2/rbs01.dbf',

'/u01/oracle/backup2/temp01.dbf',

'/u01/oracle/backup2/Users01.dbf',

'/u01/oracle/backup2/indx01.dbf',

'/u01/oracle/backup2/drsys01.dbf',

'/u01/oracle/backup2/lunar01.dbf'

Character set US7ASCII

;

11. Execute this script, create a control file

(1). Modify Initnew.ora, re-specify the name of the control file

#Control_files = ("/u01/oracle/backup2/controlfile01.ctl")

Control_files = ("/u01/oracle/backup2/control01.ctl")

It has been proven that if you don't do this, you will make an error below:

Do it in the eleventh step (4), it will be wrong

SQL> @ / u01 / oracle / back_script / ora_1381.sql

Create ControlFile Set Database "New2" ResetLogs ArchiveLog

Error At Line 1:

ORA-01503: Create ControlFile Failed

ORA-00200: ControlFile Could Not Be createdora-00202: controlfile: '/u01/oracle/backup2/controlfile01.ctl'

ORA-27038: SKGFRCRE: File EXISTS

SQL>

If an error, you will return from this step back from this step.

(2). Set Oracle_SID = New2

Oracle @ SCE> Oracle_sid = new2; export oracle_sid

(3). With pfile = / u01 / oracle / backup2 / initnew2.ora to Nomount database

$ EXIT

(4). Execute the script of the creation control file

SQL> @ / u01 / oracle / back_script / ora_9413.sql

Control File Created.

SQL>

This step is performed, and the database will create a control file in the location specified in Initnew2.ora.

#Control_files = ("/u01/oracle/backup2/controlfile01.ctl")

Control_files = ("/u01/oracle/backup2/control01.ctl")

SQL> Host

It can be seen that Control01.ctl has been created

(6). SHUTDOWN database

SQL> Shutdown Immediate

ORA-01109: Database Not Open

Database dismount.

Oracle Instance Shut Down.

====================== This is not to do ======================== ===========

(7). Modify the location and name of the control file in the initnew2.ora

#Control_files = ("/u01/oracle/backup2/controlfile01.ctl")

#Control_files = ("/u01/oracle/backup2/control01.ctl")

Control_files = ("/u01/oracle/backup2/control02.ctl")

(9). Execute the script that creates control files again

SQL> @ / u01 / oracle / back_script2 / ora_9413.sql

This step is performed, and the database will create a control file in the location specified in Initnew.ora.

#Control_files = ("/u01/oracle/backup2/controlfile01.ctl")

#Control_files = ("/u01/oracle/backup2/control01.ctl")

Control_files = ("/u01/oracle/backup2/control02.ctl")

SQL> Host

It can be seen that Control02.ctl has been created

12. Restore databases (with auto)

Thirteen, recover again (with Cancel)

Compare the "After Switch Log" in the front hot spare value day, make sure that all the logs have been restored:

After Switch log, The Ending Archive log number is:

Automatic archival enabled

Archive Destination / U01 / Oracle / Admin / SCEDB / ARCH

Oldest Online Log Sequence 2777

Next log sequence to archive 2779

The current 2779, then recovered to 2778, taking the "Cancel" when the prompt 2779

Specify log: { = suggested | filename | auto | ca ZENCEL}

Cancel ------------ Knock "Cancel"

Media recovery canceled.

SQL>

14, open the database with Open ResetLogs

This step has established the Redo Log file specified in Initnew.ora and opens the database.

SQL> ALTER DATABASE OPEN RESETLOGS;

Database altered.

SQL>

Fifteen, verify that the data is restored

For convenience, you can open a session (window),

And set Oracle_SID = SCEDB; Export Oracle_sid

Then open the old database, and the new database is compared.

In the window (old database):

Oracle @ SCE> Oracle_SID = SCEDB; Export Oracle_sid

Oracle @ SCE> Env | GREP ORACLE

Oracle_base = / u01 / oracle

Oracle_home = / u01 / oracle / orahome1

Oracle_sid = SCEDB

Oracle @ SCE> SQLPlus Lunar / Lunar

Connected to:

Oracle8i Release 8.1.7.0.0 - PRODUCTION

Jserver Release 8.1.7.0.0 - Production

SQL> SELECT *.

------------

SQL>

In the window 2 (new database):

SQL> Conn Lunar / Lunar

Connected.

SQL> SELECT *.

------------

SQL>

Verified the database except for Redo's no reply, all of the files that archived

(Refer to the initial assumption:

So far, there are 2 archives in the table TEST of the user, ie 1 and 2.

There is also an unsubmitted in REDO, ie 3;

Now you are hot in the new window (SQLUS Internal), the current Archive log is 2777,

Note that the Archive log after the hot standby is observed, and record it to control the data reply.

)

Conclusion: This thermal backup is backup for valid database
