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

Adding Disk Groups to the Cluster Configuration
For CVM 4.x or later, if the multi-node package was configured for disk group activation, the
application package should be configured with package dependency to ensure the CVM disk
group is active.
For CVM 3.5 and CVM 4.x or later (without using multi-node package) after creating units of
CVM storage with VxVM commands, you need to specify the disk groups in each package
configuration ASCII file. Use one STORAGE_GROUP parameter for each CVM disk group the
package will use. You also need to identify the CVM disk groups, file systems, logical volumes,
and mount options in the package control script. (on HP-UX releases that support them; see
“About Veritas CFS and CVM from Symantec” (page 18)).
For more detailed information on the package configuration process refer to the Managing
Serviceguard Sixteenth Edition user’s guide.
Prerequisites for Oracle 10g or 11gR1 (Sample Installation)
The following sample steps prepare a SGeRAC cluster for Oracle 10g or 11gR1. Refer to the
Oracle documentation for Oracle installation details.
1. Create Inventory Groups on each Node
Create the Oracle Inventory group if one does not exist, create the OSDBA group, and create
the Operator Group (optional).
# groupadd oinstall
# groupadd dba
# groupadd oper
2. Create Oracle User on each Node
# useradd -u 203 -g oinstall -G dba,oper oracle
3. Change the Password on each Node
# passwd oracle
4. 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
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
