Sample Configurations with SGeRAC and Oracle RAC 10gR2, March 2009

Create groups on each node

Create the Oracle Inventory group if one does not exist, create the OSDBA group, and create the

Operator Group (optional).

# /usr/sbin/groupadd oinstall

# /usr/sbin/groupadd dba

# /usr/sbin/groupadd oper

Create Oracle user on each node

# /usr/bin/useradd –u 203 –g oinstall –G dba,oper oracle

Change password on each node

# passwd oracle

Enable remote access (ssh or remsh) for Oracle user on all nodes

For remsh, add oracle user to the .rhosts file or host.equiv file.

Create symbolic links

Required if Motif 2.1 Development Environment Package is not installed.

# ln -s /usr/lib/libX11.3 /usr/lib/libX11.sl

# ln -s /usr/lib/libXIE.2 /usr/lib/libXIE.sl

# ln -s /usr/lib/libXext.3 /usr/lib/libXext.sl

# ln -s /usr/lib/libXhp11.3 /usr/lib/Xhp11.sl

# ln -s /usr/lib/libXi.3 /usr/lib/libXi.sl

# ln -s /usr/lib/libXm.4 /usr/lib/libXm.sl

# ln -s /usr/lib/libXp.2 /usr/lib/libXp.sl

# ln -s /usr/lib/libXt.3 /usr/lib/libXt.sl

# ln -s /usr/lib/libXtst.2 /usr/lib/libXtst.sl

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 c2t0d0 at 18 GB size on all nodes. Create the local file system on each node.

# umask 022

# pvcreate /dev/rdsk/c2t0d0

# mkdir /dev/vg01

# mknod /dev/vg01/group c 64 0x010000

# vgcreate /dev/vg01 /dev/dsk/c2t0d0

# 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

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

# chmod -R 775 /mnt/app/crs/oracle

The Oracle Cluster Software home directory is as follows:
