Uninstall Oracle 11g Grid Infrastructure

Oracle 11g grid infrastructure installation failure, or need to uninstall, not as troublesome as 10g CRS component Uninstall.

Take linux as an example. The procedure for manually deleting CRS at 10 Gb is as follows:

Rm-f/etc/init. d/init.css d
Rm-f/etc/init. d/init. crs
Rm-f/etc/init. d/init. crsd
Rm-f/etc/init. d/init. evmd
Rm-f/etc/rc2.d/K96init. crs
Rm-f/etc/rc2.d/S96init. crs
Rm-f/etc/rc3.d/K96init. crs
Rm-f/etc/rc3.d/S96init. crs
Rm-f/etc/rc5.d/K96init. crs
Rm-f/etc/rc5.d/S96init. crs
Rm-rf/etc/oracle/scls_scr
Rm-f/etc/inittab. crs
Cp/etc/inittab. orig/etc/inittab

In 11g, a tool named deinstallis released. For example, the software name of the Linux system is linux.x64_11gr2_deinstall.zip. After decompression, you can use it directly.

Step 1: Use the grid user to log on to the operating system. This user is the installation user of the grid infrastructure software.

/Home/grid/deinstall @ serv2 => + ASM2 $./deinstall
Location of logs/home/grid/deinstall/logs/

########### Oracle deinstall & deconfig tool start ############

Usage:

Deinstall-home <Complete path of Oracle home>
[-Silent]
[-Checkonly]
[-Local]
[-Paramfile <complete path of input parameter property file>]
[-Params <name1 = value [name2 = value...]>]
[-O <complete path of directory for saving files>]
[-Help |-h: Type-h or-help to get more information on each o
F the above options.]
Specify any of the above options.

Step 2: Use deinstall-home/u01/app/11.2.0/grid to uninstall the installed file

/Home/grid/deinstall @ serv2 => + ASM2 $./deinstall-home/u01/app/11.2.0/grid

Run the following command as the root user or the administrator on node "serv2 ".

/Home/grid/deinstall/perl/bin/perl-I/home/grid/deinstall/perl/lib-I/home/grid/
Deinstall/crs/install/home/grid/deinstall/crs/install/rootcrs. pl-force-delet
E-paramfile/home/grid/deinstall/response/deinstall_Ora11g_gridinfrahome1.rsp-
Lastnode

Press Enter after you finish running the above commands

This step is used to generate the configuration file/home/grid/deinstall/response/deinstall_Ora11g_gridinfrahome1.rsp

Step 3: Use root to execute the perl script of the configuration file generated in the previous step on the node

/Home/grid/deinstall/perl/bin/perl-I/home/grid/deinstall/perl/lib-I/home/grid/
Deinstall/crs/install/home/grid/deinstall/crs/install/rootcrs. pl-force-delet

Lastnode

Now, uninstalling grid infrastructure is complete. No ohasd-related files are available in/etc/init. d.
