Using Serviceguard Extension for RAC, 7th Edition, September 2008

5. Enable Remote Access (ssh and remsh) for Oracle User on all Nodes
6. Create File System for Oracle Directories
In the following samples, /mnt/app is a mounted file system for Oracle software. Assume
there is a private disk c4t5d0 at 18 GB size on all nodes. Create the local file system on each
node.
# umask 022
# pvcreate /dev/rdsk/c4t5d0
# mkdir /dev/vg01
# mknod /dev/vg01/group c 64 0x010000
# vgcreate /dev/vg01 /dev/dsk/c4t5d0
# lvcreate -L 16000 /dev/vg01
# newfs -F vxfs /dev/vg01/rlvol1
# mkdir -p /mnt/app
# mount /dev/vg01/lvol1 /mnt/app
# chmod 775 /mnt/app
7. Create Oracle Cluster Software Home Directory
For installing Oracle Cluster Software on local file system, create the directories on each
node.
# mkdir -p /mnt/app/crs/oracle/product/10.2.0/crs
# chown -R oracle:oinstall \ /mnt/app/crs/oracle/product/10.2.0/crs
# chmod -R 775 /mnt/app/crs/oracle/product/10.2.0/crs
8. Create Oracle Base Directory (for RAC Binaries on Local File System)
If installing RAC binaries on local file system, create the oracle base directory on each node.
# mkdir -p /mnt/app/oracle
# chown -R oracle:oinstall /mnt/app/oracle
# chmod -R 775 /mnt/app/oracle
# usermod -d /mnt/app/oracle oracle
9. Create Oracle Base Directory (For RAC Binaries on Cluster File System)
If installing RAC binaries on Cluster File System, create the oracle base directory once since
this is CFS directory visible by all nodes. The CFS file system used is /cfs/mnt1.
# mkdir -p /cfs/mnt1/oracle
# chown -R oracle:oinstall /cfs/mnt1/oracle
# chmod -R 775 /cfs/mnt1/oracle
# chmod 775 /cfs
# chmod 775 /cfs/mnt1
Modify oracle user to use new home directory on each node.
# usermod -d /cfs/mnt1/oracle oracle
10. Prepare Shared Storage on SLVM
This section assumes the OCR, Vote device, and database files are created on SLVM volume
group vg_ops.
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.
