各系统CRS卸载 oracle

1. Run the rootdelete.sh script then the rootdeinstall.sh script from the $ORA_CRS_HOME/install directory on any nodes you are removing CRS from. Running these scripts should be sufficent to clean up your CRS install.

 

Rootdelete.sh accepts options like nosharedvar/sharedvar, and nosharedhome/sharedhome.

Make yourself familiar with these options by reading the Oracle Clusterware and Oracle Real Application Clusters Administration and Deployment Guide.

 

If for some reason you have to manually remove the install due to problems with the scripts, continue to step 2:

 

2. Stop the Nodeapps on all nodes:

1. srvctl stop nodeapps -n

 

3. Prevent CRS from starting when the node boots. To do this issue the following as root:

 

Sun:

1. rm /etc/init.d/init.cssd

2. rm /etc/init.d/init.crs
3. rm /etc/init.d/init.crsd
4. rm /etc/init.d/init.evmd

5. rm /etc/rc3.d/K96init.crs

6. rm /etc/rc3.d/S96init.crs
7. rm -Rf /var/opt/oracle/scls_scr
8. rm -Rf /var/opt/oracle/oprocd
9. rm /etc/inittab.crs
10. cp /etc/inittab.orig /etc/inittab

 

 

 

Linux:

1. rm /etc/oracle/*

2. rm -f /etc/init.d/init.cssd

3. rm -f /etc/init.d/init.crs

4. rm -f /etc/init.d/init.crsd

5. rm -f /etc/init.d/init.evmd
6. rm -f /etc/rc2.d/K96init.crs
7. rm -f /etc/rc2.d/S96init.crs
8. rm -f /etc/rc3.d/K96init.crs

9. rm -f /etc/rc3.d/S96init.crs

10. rm -f /etc/rc5.d/K96init.crs

11. rm -f /etc/rc5.d/S96init.crs

12. rm -Rf /etc/oracle/scls_scr

13. rm -f /etc/inittab.crs
14. cp /etc/inittab.orig /etc/inittab

 

HP-UX:

1. rm /sbin/init.d/init.cssd

2. rm /sbin/init.d/init.crs

3. rm /sbin/init.d/init.crsd

4. rm /sbin/init.d/init.evmd

5. rm /sbin/rc2.d/K960init.crs

6. rm /sbin/rc2.d/K001init.crs

7. rm /sbin/rc3.d/K960init.crs

8. rm /sbin/rc3.d/S960init.crs

9. rm -Rf /var/opt/oracle/scls_scr

10. rm -Rf /var/opt/oracle/oprocd

11. rm /etc/inittab.crs

12. cp /etc/inittab.orig /etc/inittab

 

 

 

 

 

HP Tru64:

1. rm /sbin/init.d/init.cssd

2. rm /sbin/init.d/init.crs

3. rm /sbin/init.d/init.crsd

4. rm /sbin/init.d/init.evmd

5. rm /sbin/rc3.d/K96init.crs

6. rm /sbin/rc3.d/S96init.crs

7. rm -Rf /var/opt/oracle/scls_scr

8. rm -Rf /var/opt/oracle/oprocd

9. rm /etc/inittab.crs

10. cp /etc/inittab.orig /etc/inittab

 

IBM AIX:

1. rm /etc/init.cssd

2. rm /etc/init.crs
3. rm /etc/init.crsd

4. rm /etc/init.evmd

5. rm /etc/rc.d/rc2.d/K96init.crs

6. rm /etc/rc.d/rc2.d/S96init.crs

7. rm -Rf /etc/oracle/scls_scr
8. rm -Rf /etc/oracle/oprocd
9. rm /etc/inittab.crs

10. cp /etc/inittab.orig /etc/inittab

 

4. If they are not already down, kill off EVM, CRS, and CSS processes or reboot the node:

1. ps -ef | grep crs

2.  

3. kill
4.  
5. ps -ef | grep evm

6.  

7. kill

8.  

9. ps -ef | grep css

10.  

11. kill

 

Do not kill any OS processes, for example icssvr_daemon process !

5. If there is no other Oracle software running (like listeners, DB's, etc...), you can remove the files in /var/tmp/.oracle or /tmp/.oracle. Example:

rm -f /var/tmp/.oracle/* or rm -f /tmp/.oracle/*

6. Remove the ocr.loc Usually the ocr.loc can be found at /etc/oracle

7. De-install the CRS home in the Oracle Universal Installer

8. Remove the CRS install location.

 

9. Clean out the OCR and Voting Files with dd commands. Example:

1. dd if=/dev/zero of=/dev/rdsk/V1064_vote_01_20m.dbf bs=1M count=256

2. dd if=/dev/zero of=/dev/rdsk/ocrV1064_100m.ora bs=1M count=256

See the Clusterware Installation Guide for sizing requirements...

 

If you placed the OCR and voting disk on a shared filesystem, remove them.

 

If you are removing the RDBMS installation, also clean out any ASM disks if

they have already been used.

 

10. The /tmp/CVU* dir should be cleaned also to avoid the cluvfy misreporting.

 

11. It is good practice to reboot the node before starting the next install.

 

12.If you would like to re-install CRS, follow the steps in the RAC Installation manual.
