Oracle9i preinstallation tasks involve:
Storage Foundation and High Availability Solutions 5.0
Main Menu > Prepare to install Oracle
. ............................................................... .
This step helps you complete sysadmin tasks before installing Oracle software.
. ............................................................... .
1) [Perform all the following tasks]
2) Create userid and groupid for Oracle
3) Configure private IP addresses for CRS (Oracle 10g only)
4) Create disk groups, volumes and file systems for Oracle ** INSTRUCTIONS ONLY **
This menu option also takes you through other tasks:
Storage Foundation and High Availability Solutions 5.0
Main Menu > Prepare to install Oracle > Create userid and groupid for Oracle
. ............................................................... .
This step creates user and group ids on all cluster nodes for Oracle.
. ............................................................... .
Enter Oracle UNIX user name: [b] (oracle) oracle
Enter Oracle UNIX user id (numerical): [b] 100
Enter Oracle UNIX user home dir: [b] /home/oracle
Enter Oracle UNIX group name: [b] (oinstall) oinstall
Enter Oracle UNIX group id (numerical): [b] 1000
User oracle does not exist on any node. Do you want to create it with the information provided [y,n,q] (y) y
Creating user oracle on galaxy .......................... Done
Creating user oracle on nebula .......................... Done
Create secondary groups for Oracle user (optional)
Storage Foundation and High Availability Solutions 5.0
Main Menu > Prepare to install Oracle > Create secondary groups for Oracle user
. ............................................................... .
This step creates secondary group ids on all cluster nodes. Oracle requires some other special groups for identifying
operating system accounts that have database admin (SYSDBA) privileges and for those accounts that have limited sets of
database admin (SYSOPER) privileges. You should create such groups on all systems and Oracle user should be part of these
. ............................................................... .
Do you want to create another secondary group for Oracle user? [y,n,q] (y) y
Enter Oracle UNIX secondary group name: [b] oper
Enter Oracle UNIX secondary group id (numerical): [b] 1001
Group oper does not exist on any node. Do you want to create it with the information provided [y,n,q] (y) y
Creating group oper on galaxy ................................. Done
Adding Oracle user (oracle) to group (oper) on galaxy ......... Done
Creating group oper on nebula ................................. Done
Adding Oracle user (oracle) to group (oper) on nebula ......... Done

Verify communication for Oracle user
Storage Foundation and High Availability Solutions 5.0
Main Menu > Prepare to install Oracle > SSH and RSH verification for Oracle user
. ............................................................... .
This step verifies ssh and rsh permissions for oracle user on all the nodes. Oracle installation requires ssh and rsh
permissions to be set for Oracle user.
If ssh and rsh permissions have not been set for oracle user by this time, then you can set them by switching to another
console. After setting the permissions you can come back to this console and continue with the installer.
Please NOTE! During SSH verification, if you are prompted for entering password for some node(s), then it means SSH is not
configured properly for Oracle user on those nodes, in which case you need to configure it on those nodes.
. ............................................................... .
Do you want to perform ssh verification? [y,n,q] (y) n
Main Menu > Prepare to install Oracle > SSH and RSH verification for Oracle user

Checking remsh communication for oracle user on galaxy ..... Checked
Checking remsh communication for oracle user on nebula ..... Checked

Main Menu > Prepare to install Oracle > Configure private IP addresses for CRS
. ............................................................... .
This step will configure private IP addresses using PrivNIC resource of VCS.
* You must use all LLT links for PrivNIC.
* Network 1 of all nodes must be physically connected.
Similarly Networks 2, 3, and so on
* IP addresses used here must be manually added to /etc/hosts on all nodes
This step is NOT required if you will only install Oracle 9i.
. ............................................................... .
Enter the private IP for galaxy: [b] 10.12.20.20
Checking 10.12.20.20 in /etc/hosts on galaxy ................ exists
Discovering NICs on galaxy ............... discovered lan0 lan1 lan2
Enter the NIC 1 for private network for galaxy (x if done): [b] lan1
Enter the NIC 2 for private network for galaxy (x if done): [b] lan2
Enter the NIC 3 for private network for galaxy (x if done): [b] x
Enter the private IP for nebula: [b] 10.12.20.21
Checking 10.12.20.21 in /etc/hosts on nebula ................ exists
Discovering NICs on nebula ............... discovered lan0 lan1 lan2
Enter the NIC 1 for private network for nebula (x if done): [b] (lan1)
Enter the NIC 2 for private network for nebula (x if done): [b] (lan2)
Enter the NIC 3 for private network for nebula (x if done): [b] x
CRS private IP configuration information verification
Is this information correct? [y,n,q,b] (y) y
Changing configuration to read-write mode ................. success
Adding new ora_priv resource .............................. success
Saving configuration ...................................... success

Main Menu > Prepare to install Oracle > Create disk groups, volumes and file systems for Oracle ** INSTRUCTIONS ONLY **
. ............................................................... .
Before continuing, login to all cluster nodes and complete the following.
1. Create CVM volumes or CFS directories on shared storage for:
* OCR and Vote-device (for 10gR1 and 10gR2 only)
(must be on CVM volume for 10.2 and 10.1.0.5 and above)
2. Create local or shared file systems for CRS Home and Oracle Home.
3. Change the permission of all of the above to oracle user and group.
4. Create VCS resources for CVM Volumes and CFS files. Refer to sample configurations in /etc/VRTSvcs/conf/sample_rac/ directory.
Example for Oracle data disk group, volume and mount creation:
vxdg -s init oradatadg HDS0_30 IBM0_30 EMC0_30 HDS1_30 #to create shared disk group
vxassist -g oradatadg make oradatavol 6G layout=striped-mirror #to create volume
mkdir /oradata #to create a mount point
/dev/vx/rdsk/oradatadg/oradatavol #to create shared file system
mount -F vxfs -o cluster,largefiles /dev/vx/dsk/oradatadg\
/oradatavol/oradata #to mount shared file system
chown -R oracle:oinstall /oradata #to change permissions
