a. Change Permission of Shared Logical Volume Group
This section assumes the OCR, Vote device, and database files are created on
SLVM volume group vg_ops.
# chmod 755 /dev/vg_ops
b. Change Permission and Ownership of Oracle Cluster Software Vote Device
and Database Files
# chown oracle:oinstall /dev/vg_ops/r*
# chmod 660 /dev/vg_ops/r*
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
