This article is about how to install Oracle database software by cloning. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

I. preparatory work

Sometimes, if the configurations of several machines are similar, you don't need to install the database software over and over again. In this case, clone installation can be used, which is faster than graphical interface and silent installation.

Source host: machine A

Target host: B machine

1. B machine creates users and user groups

# groupadd-g 501 oinstall

# groupadd-g 502 dba

# groupadd-g 503 oper

# useradd-g oinstall-G dba,oper-u 501-d / home/oracle oracle

Parameter description-g specifies the user group

-G specifies additional group

-d specify user directory

Activate oracle user (change oracle user password)

# passwd oracle

2. B machine creates database installation directory and assigns permissions

# mkdir-p / u01/app/oracle/product/11.2.0/db_1

# chown-R oracle:oinstall / U01

# chown-R oracle:oinstall / oradata

# chown-R oracle:oinstall / backup

# chown-R oracle:oinstall / archivelog

# chmod-R 775 / U01

# chmod-R 775 / oradata

# chmod-R 775 / backup

# chmod-R 775 / archivelog

Note: in a normal production environment, we install the database software (ORACLE_HOME) locally and the data (oradata/backup/archivelog) in storage

3. Check that the modified kernel parameters of machine B are the same as those of machine A.

# vi / etc/sysctl.conf

4. Check that the modified user limit file of machine B is consistent with that of machine A.

# vi / etc/security/limits.conf

5. Check that the Oracle environment variable of machine B is the same as that of machine A (oracle user)

$vi .bash _ pfile

6. B machine installs the corresponding requirement package

# yum install-y binutils compat* elfutils-libelf elfutils-libelf-devel glibc glibc-common glibc-devel gcc gcc-c++ libaio libgcc libstdc++ libstdc++-devel make sysstat unixODBC-devel libaio-devel ksh

2. Start cloning

A machine operation:

1. Shut down the database

$sqlplus / as sysdba

SQL > shutdown immediate

two。 Turn off snooping

$lsnrctl stop

3. Package / u01/app/oracle/product/ directory

$cd / u01/app/oracle

$tar-cvf / u01/app/oracle/product.tar product/

4. Transfer the package to the B machine

$scp product.tar oracle@IP:/u01/app/oracle

B machine operation:

1. Extract the tar package

$cd / u01/app/oracle

$tar-xvf product.tar

two。 Check the listener.ora and tnsname.ora files in the $ORACLE_HOME/network/admin directory, and modify the HOST field to point to the local machine.

3. Run runinstall

$cd $ORACLE_HOME/oui/bin

$. / runInstall-silent-clone ORACLE_BASE='/u01/app/oracle' ORACLE_HOME='/u01/app/oracle/product/11.2.0/db_1/' ORACLE_HOME_NAME='ORACLE_HOME_1' (custom name)

WARNING:A new inventory has been created in this session. However, it has not yet been registered as the central inventory of this system.

To register the new inventory please run the script'/ u01 with root privileges.

If you do not register the inventory, you may not be able to update or patch the products you installed.

The following configuration scripts need to be executed as the "root" user.

/ u01/app/oraInventory/orainstRoot.sh

/ u01/app/oracle/product/11.2.0/db_1/root.sh

To execute the configuration scripts:

1. Open a terminal window

2. Log in as "root"

3. Run the scripts

The cloning of ORACLE_HOME_1 was successful.

Please check'/ u01/app/oraInventory/logs/cloneActions2018-12-05mm 08-32-20AM.log 'for more details.

At this point, the installation of the Oracle database software has been completed

4. Turn on monitoring

$lsnrctl start

5. Verify the function of sqlplus

$sqlplus / as sysdba
