Using Serviceguard Extension for RAC, 8th Edition, March 2009

c. Change Permission of OCR Device
# chown root:oinstall /dev/vg_ops/rora_ocr
# chmod 640 /dev/vg_ops/rora_ocr
d. Create Raw Device Mapping File for Oracle Database Configuration Assistant
In this example, the database name is “ver10”
# ORACLE_BASE=/mnt/app/oracle; export ORACLE_BASE
# mkdir -p $ORACLE_BASE/oradata/ver10
# chown -R oracle:oinstall $ORACLE_BASE/oradata
# chmod -R 755 $ORACLE_BASE/oradata
The following is a sample of the mapping file for DBCA:
system=/dev/vg_ops/ropssystem.dbf
sysaux=/dev/vg_ops/ropssysaux.dbf
undotbs1=/dev/vg_ops/ropsundotbs01.dbf
undotbs2=/dev/vg_ops/ropsundotbs02.dbf
example=/dev/vg_ops/ropsexample1.dbf
users=/dev/vg_ops/ropsusers.dbf
redo1_1=/dev/vg_ops/rops1log1.log
redo1_2=/dev/vg_ops/rops1log2.log
redo2_1=/dev/vg_ops/rops2log1.log
redo2_2=/dev/vg_ops/rops2log2.log
control1=/dev/vg_ops/ropsctl1.ctl
control2=/dev/vg_ops/ropsctl2.ctl
control3=/dev/vg_ops/ropsctl3.ctl
temp=/dev/vg_ops/ropstmp.dbf
spfile=/dev/vg_ops/ropsspfile1.ora
In this sample, create the DBCA mapping file and place at:
/mnt/app/oracle/oradata/ver10/ver10_raw.conf.
11. Prepare Shared Storage on CFS
This section assumes the OCR, Vote device, and database files are created on CFS directories.
The OCR and vote device reside on /cfs/mnt3 and the demo database files reside on /cfs/
mnt2.
a. Create OCR and Vote Device Directories on CFS
Create OCR and vote device directories on Cluster File System. Run commands only
on one node.
# chmod 775 /cfs
# chmod 755 /cfs/mnt3
# cd /cfs/mnt3
# mkdir OCR
# chmod 755 OCR
# mkdir VOTE
# chmod 755 VOTE
# chown -R oracle:oinstall /cfs/mnt3
b. Create Directory for Oracle Demo Database on CFS
Create the CFS directory to store Oracle database files. Run commands only on one
node.
# chmod 775 /cfs
# chmod 775 /cfs/mnt2
