As your organization grows, so too does your need for more application and database resources to support the company's IT systems.
Oracle RAC 11g provides a scalable framework which allows DBA's to effortlessly extend the database tier to support this increased demand.
The current Oracle RAC is not using Grid Naming Service (GNS) to assign IP addresses.
Although this article was written and tested on Cent OS 5 Linux, it should work unchanged with Red Hat Enterprise Linux 5 or Oracle Linux 5.
To add nodes to an existing Oracle RAC, Oracle Corporation recommends using the Oracle cloning procedures which are described in the Oracle Universal Installer and OPatch User's Guide.
The Dell Power Edge T100 includes an embedded Broadcom(R) Net Xtreme IITM 5722 Gigabit Ethernet NIC that will be used to connect to the public network.
A second NIC adapter will be used for the private network (RAC interconnect and Openfiler networked storage).
The hardware used to build the third node in our example Oracle RAC 11g environment consists of a Linux server and components that can be purchased at many local computer stores or over the Internet.
Dual Core Intel(R) Xeon(R) E3110, 3.0 GHz, 6MB Cache, 1333MHz 4GB, DDR2, 800MHz 160GB 7.2K RPM SATA 3Gbps Hard Drive Integrated Graphics - (ATI ES1000) Integrated Gigabit Ethernet - (Broadcom(R) Net Xtreme IITM 5722) 16x DVD Drive No Keyboard, Monitor, or Mouse - (Connected to KVM Switch) Each Linux server for Oracle RAC should contain at least two NIC adapters.machines, networking equipment, and internal / external hard drives).Ensure that the hardware you purchase from the vendor is supported on Red Hat Enterprise Linux 5 and Openfiler 2.3 (Final Release).Contained in this new article are the steps required to add a single node to an already running and configured two-node Oracle RAC 11g Release 2 (188.8.131.52) for Linux x86_64 environment on the Cent OS 5 Linux platform.All shared disk storage for Oracle RAC is based on i SCSI using Openfiler running on a separate node (also known as the Network Storage Server).Select the appropriate NIC adapter that is compatible with the maximum data transmission speed of the network switch to be used for the private network.Tags: Adult Dating, affair dating, sex dating
