Hi Gurus ,
As per Oracle docs "Normal redundancy disk groups provide 3 voting disk files, 1 OCR and 2 copies(one primary and one secondary mirror).
Does it means there are 2 OCR in this diskgroup ? .Then ,
Where is the OCR primary and Mirror created in this case?Are they been on separate failure group ? Then how can I check the same through asmcmd?
Here is my environment set up
[grid@xxxx01 ~]$ ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 3
Total space (kbytes) : 262120
Used space (kbytes) : 2800
Available space (kbytes) : 259320
ID : 1074808153
Device/File Name : +OCR_VOTE
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 bypassed due to non-privileged user
My +OCR_VOTE is in normal redundancy , while looking at ASM level
[grid@xxxx01 ~]$ asmcmd
ASMCMD>
ASMCMD> cd +OCR_VOTE
ASMCMD> ls
ehrptpi-cluster/
ASMCMD> cd xxxxxi-cluster/
ASMCMD> ls
ASMPARAMETERFILE/
OCRFILE/
ASMCMD> cd OCRFILE/
ASMCMD> ls -l
Type Redund Striped Time Sys Name
OCRFILE MIRROR COARSE JAN 07 20:00:00 Y REGISTRY.255.763526561
ASMCMD>
Here I can see only one OCR file . Then what is meant by 1 OCR and 2 copies ?
Can somebody shed some light on how OCR mirroring actually works ?
Thanks and Regards,
Mahi
