Soa updating zone files

While assigning IP addresses using GNS certainly has its benefits and offers more flexibility over manually defining static IP addresses, it does come at the cost of complexity and requires components not defined in this guide.

For example, activating GNS in a cluster requires a DHCP server on the public network which falls outside the scope of building an inexpensive Oracle RAC.

All name resolution requests for the cluster within a sub-domain delegated by the DNS are handed off to GNS using multicast Domain Name Service (m DNS) included within the Oracle Clusterware.

Using GNS eliminates the need for managing IP addresses and name resolution and is especially advantageous in a dynamic cluster environment where nodes are often added or removed.

This guide is provided for educational purposes only, so the setup is kept simple to demonstrate ideas and concepts.

For example, the shared Oracle Clusterware files (OCR and voting files) and all physical database files in this article will be set up on only one physical disk, while in practice that should be stored on multiple physical drives configured for increased performance and redundancy (i.e. In addition, each Linux node will only be configured with two network interfaces — one for the public network ().

In addition to this guide, users should also consult the following Oracle documents to gain a full understanding of alternative configuration options, installation, and administration with Oracle RAC 11g. Powered by r Path Linux, Openfiler is a free browser-based network storage management utility that delivers file-based Network Attached Storage (NAS) and block-based Storage Area Networking (SAN) in a single framework.

The entire software stack interfaces with open source applications such as Apache, Samba, LVM2, ext3, Linux NFS and i SCSI Enterprise Target.

Prior to Oracle Clusterware 11g Release 2, the only method available for assigning IP addresses to each of the Oracle RAC nodes was to have the network administrator manually assign static IP addresses in DNS — never to use DHCP.

Openfiler combines these ubiquitous technologies into a small, easy to manage solution fronted by a powerful web-based management interface.

Openfiler supports CIFS, NFS, HTTP/DAV, FTP, however, we will only be making use of its i SCSI capabilities to implement an inexpensive SAN for the shared storage components required by Oracle RAC 11g.

The operating system (r Path Linux) and the Openfiler application will be installed on one internal SATA disk.

A second internal 73GB 15K SCSI hard disk will be configured as a single volume group that will be used for all shared disk storage requirements.
