Installing Oracle10g Cluster Ready Services
In Oracle10g, the Clusterware has been placed on a separate CD which installs Cluster Ready Services. You must install from this disk
before installing from the Oracle10g Database installaon CD. In addion, you must complete some pre-installaon steps before
starng the Cluster Ready Services installaon.
Pre-installaon Steps
Before installing Cluster Ready Services, you must create logical volumes on shared disk. The procedure to do this was outlined in a
previous secon. If you are using ASM, you should create separate parons for the vong disk, the OCR, Oracle data les, and the
Oracle Recovery area. You also have the opon of installing Oracle executables on a shared disk drive, which would require an extra
paron. If you are using OCFS, you may combine the OCR and vong disk on one paron. For OCFS, Oracle stores the
vong disk as a simple le on the quorum paron.
Before you can use ASM on external disk arrays, the disks must be stamped with a special header. You can stamp the disks with asm-
tool (command line) or asmtoolg (GUI version). Below is an example using asmtoolg:
1. Double-click asmtoolg.
2. Select the “Add or change label” opon, then click “Next”. asmtoolg will show the devices available on the system. Label
types include:
a. “Candidate device”- unrecognized disks
b. “Oracle raw device le” – raw device les
c. “Stamped ASM disk”
d. “Unstamped ASM disks.”
e. Windows le systems (such as NTFS). Windows le systems and Microso Dynamic disks cannot be used for
ASM.
3. On the “Stamp Disks” screen, select the disks to stamp. For ease of use, ASM an generate unique stamps for all of the
devices selected for a given prex. For example, if the prex is DATA, the rst ASM link name would be ORCLDISKDATA0.
4. Oponally, select a disk to edit the individual stamp (ASM link name).
5. Click “Next”.
6. Click “Finish”.
Cluster Ready Services Installaon Steps
Use the following steps to install Cluster Ready Services:
1. Run the setup.exe command on the Oracle Cluster Ready Services Release 1 (10.1.0.2) CD-ROM. This displays the Oracle
Universal Installer (OUI) Welcome page. Click “Next”.
2. In the Specify File Locaons page, choose the default path for the CRS products or browse to select a new path. Also
choose the locaon of the CRS Home directory. Note: this cannot be the same as the Oracle Home that you will choose later
for the database. Only ASM directories may reside on shared disk for the CRS Home. For OCFS installaons, the CRS
products path and CRS Home must exist on all cluster members. Note that the individual CRS Home directories cannot
reside on an Oracle Cluster File System. Click “Next”.
