  Oracle Database Tips by Donald Burleson

Oracle10g Grid Computing with RAC
Chapter 6 - Install, Configure and Database Creation

CRS Installation

Figure 6.10 Oracle Cluster Registry Page

Note that at the time of writing of this book, OCFS does not support the CRS files. The CRS files can be located on the following: 1) RAW device. 2) Any Cluster File system other than OCFS. 3) NFS file system on a certified NAS device.

However, this situation may change with OCFS Rel 2.0

  1. Next, the Voting Disk Information page( Fig. 6.11) appears. CSS Voting Disk is used to arbitrate the ownership of the cluster nodes in the event of split-brain syndrome. Voting disk is same as the quorum disk, a term more familiar to all of us. Voting Disk needs to reside either on a cluster file system or on a shared raw disk. In our installation, we have pre-created a voting disk file css_voting_disk and specified the in the voting disk page.

Figure 6.11 Select the CSS Voting Disk

Note that the storage size for the OCR should be at least 100MB and the storage size for the voting disk should be at least 20MB.

  1. Next, the OUI displays a dialog asking you to run the script on all of the nodes. After the script processing completes, the OUI displays a Summary page (Fig. 6.12) as shown next.
