Relocate OCR from +DATA1 to different disks

Task:-
 Relocate OCR from +DATA1 to +DATA2

Requirement:-

Need +DATA2 disk group 


Step 1: Check current OCR location 


[root@rac1 bin]# ./ocrcheck

         Total space (kbytes)     :     262120
         Used space (kbytes)      :       3064
         Available space (kbytes) :     259056
         ID                       :  918475055
         Device/File Name         :     +DATA1

                                    Device/File not configured

                                    Device/File not configured

                                    Device/File not configured

                                    Device/File not configured

         Cluster registry integrity check succeeded


         Logical corruption check succeeded

[root@rac1 bin]#
[root@rac1 bin]# pwd
/u01/app/11.2.0/grid_1/bin
[root@rac1 bin]# ./ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          3
         Total space (kbytes)     :     262120

                                    Device/File not configured

                                    Device/File not configured

                                    Device/File not configured

         Cluster registry integrity check succeeded

         Logical corruption check succeeded

Step 2: Verify asm diskgroup for relocate 

[root@rac1 bin]# oracleasm listdisks
DISK1
DISK2
DISK3

Step 3:-  Now add +DATA2 as new OCR location and verify using below command  
[root@rac1 bin]#
[root@rac1 bin]# ./ocrconfig -add +DATA2
[root@rac1 bin]#
[root@rac1 bin]#
[root@rac1 bin]# ./ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          3
         Total space (kbytes)     :     262120
         Used space (kbytes)      :       3064

         ID                       :  918475055
         Device/File Name         :     +DATA1
                                    Device/File integrity check succeeded
         Device/File Name         :     +DATA2
                                    Device/File integrity check succeeded

                                    Device/File not configured

                                    Device/File not configured

                                    Device/File not configured

         Cluster registry integrity check succeeded

         Logical corruption check succeeded

Step4:- Now delete old location +DATA1 using below command  and verify

[root@rac1 bin]# ./ocrconfig -delete +DATA1
[root@rac1 bin]#
[root@rac1 bin]#
[root@rac1 bin]# ./ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          3

         Available space (kbytes) :     259056
         ID                       :  918475055
         Device/File Name         :     +DATA2
                                    Device/File integrity check succeeded

                                    Device/File not configured

                                    Device/File not configured

                                    Device/File not configured

                                    Device/File not configured

         Cluster registry integrity check succeeded

         Logical corruption check succeeded

ORA-00845: MEMORY_TARGET not supported on this system

Cause:

Memory Target  error come due to lack of tmp space on server .



[oracle@rac1 ~]$ df -h
Filesystem                   Size  Used Avail Use% Mounted on
/dev/mapper/vg_rac1-lv_root   26G   20G  5.0G  80% /

Solution :

Need to increase temp space on server

# umount tmpfs
# mount -t tmpfs shmfs -o size=4048m /dev/shm

Make entry in fstab file on /etc/fstab
