Integrated physical migration of Oracle database on Linux and platform

Overall physical migration of Linux with platform database
Requirement: A machine is no longer used, to migrate Oracle a machine to machine B.
Previous articles on similar requirements: http://www.linuxidc.com/Linux/2015-05/117556.htm
The purpose of this article is to use the integrated script of automation to realize the whole migration of the same platform database.
1.A Machine operation

2.B Machine operation

A machine operation

0. System version:
[Email protected] tmp]# uname-a
Linux db-a 2.6.32-358.el6.x86_64 #1 SMP Tue Jan 11:47:41 EST x86_64 x86_64 x86_64 gnu/linux
[Email protected] tmp]# cat/etc/issue
Red Hat Enterprise Linux Server release 6.4 (Santiago)
Kernel \ r on an \m

1.A Database Current Information
Select Status from v$instance UNION ALL
Select Open_mode from V$database UNION ALL
SELECT * from v$version where rownum = 1;

2. Confirm the location of the parameter file and control file
Show Parameter Pfile
Show Parameter Control_files

You need to create a pfile file based on the current SPFile, which is used later.
Create Pfile from SPFile;

3. Location of data files, temporary files, redo log files
Set Linesize pagesize 100
Select name from V$datafile UNION ALL
Select name from V$tempfile UNION ALL
Select member from V$logfile;

4. Clean Shutdown Database:
Shutdown immediate;

5. Identify the Oracle software catalog and package it to B machine
Echo $ORACLE _base
/ora/app/oracle
Tar-zcvf/tmp/oracle.tar.gz/ora/app/oracle

Copy the packaged Oracle software catalog and all the parameter files, control files, data files, temporary files, and redo log files to the B machine.

B Machine Operation

0. System version:
[Email protected] irnop]# uname-a
Linux db-b 2.6.32-431.el6.x86_64 #1 SMP Sun Nov 22:19:54 EST x86_64 x86_64 x86_64 gnu/linux
[Email protected] irnop]# cat/etc/issue
Red Hat Enterprise Linux Server release 6.5 (Santiago)
Kernel \ r on an \m

1. Installing dependency packages and adjusting system parameters

Slightly. Refer to: http://www.linuxidc.com/Linux/2015-05/117559.htm

2. Unzip the oracle_home to the B machine planning Software installation directory:/u01/app/oracle
Tar zxvf oracle.tar.gz

Extracted Oracle Directory direct MV to/u01/app

3. Modify the parameter file Pfile and start the database to Nomount

Modify the memory value of the database according to the actual condition of the B machine and confirm that the path written in the parameter file exists.
Startup Nomount pfile= ' $ORACLE _home/dbs/initirnop.ora '
sql> startup Nomount pfile= ' $ORACLE _home/dbs/initirnop.ora '
ORACLE instance started.

Total System Global area 2.3717E+10 bytes
Fixed Size 2239176 bytes
Variable size1.3153e+10 bytes
Database buffers 1.0536E+10 bytes
Redo buffers 25612288 bytes

4. Boot to mount
Sql> ALTER DATABASE Mount;

Database altered.

5. Rename redirection of data files, temporary files, log files
Set Linesize pagesize 100
Select ' ALTER DATABASE rename file ' | | name| | ' to '/xxx ' | | name| | '; ' from V$datafile UNION ALL
Select ' ALTER DATABASE rename file ' | | name| | ' to '/xxx ' | | name| | '; ' from V$tempfile UNION ALL
Select ' ALTER DATABASE rename file ' | | member| | ' to '/xxx ' | | member| | '; ' from V$logfile;

Replace Old_name with new_name according to the actual situation
Old_name:/xxx/oradata
New_name:/new/oradata

Then execute the redirect SQL to check that the current path is correct:
Select name from V$datafile UNION ALL
Select name from V$tempfile UNION ALL
Select member from V$logfile;

To modify the system's directory permissions:
Chown-r Oracle:oinstall/new/oradata

6. Open the database:
sql> ALTER DATABASE open;
