Multi tasking operating systems executes processes in a time slice fashion sharing the processing resources base on their current privilege. Privileges are not constant and elevate if they have not received an execution allocation in the processor after a given time. This is to ensure that all processes get executed regardless of priority although a process can get squeezed out of the time allocation alltogether if the system is overloaded. Higher priority processes may get more time allocated on the processor than a lower priority process but it is likely that the lower process will get some processor allocation. Many system process which manage the system environment execute at an elevated priority in order to guarentee that they get executed. User processes can have their priority elevated using the nice command. Nice values have a range from 2. Beware that if the priority is elevated higer than a system process, the behavior of the system may be compromised. Modify process scheduling priority. Lower scheduling priority runs slower and less likely to slow you down. Default for nice n is 1. Show default for any process nice executable. Shows nice value to be used if run.

Assigning IP Address. Prior to Oracle Clusterware 1. Release 2, the only method available for. IP addresses to each of the Oracle RAC nodes was to have the network administrator. IP addresses in DNS never to use DHCP. This would include the public IP address for the node, the RAC interconnect, virtual IP address VIP. Release 2, the. Single Client Access Name. SCAN virtual IP addresss. Oracle Clusterware 1. Release 2 now provides two methods for assigning IP addresses. Oracle RAC nodes. Assigning IP addresses dynamically using. Grid Naming Service. GNS which makes use of DHCP. The traditional method of manually assigning static IP addresses in. Domain Name Service. DNS. Assigning IP Addresses Dynamically using Grid Naming Service GNS. A new method for assigning IP addresses was introduced in. Oracle Clusterware 1. Release 2 named Grid Naming Service GNS. VIP addresses to be dynamically assigned using DHCP. GNS and DHCP are key elements to Oracles new Grid Plug and Play GPn. P. feature that, as Oracle states, eliminates per node configuration. GNS enables a dynamic Grid Infrastructure. All name resolution requests for the cluster within a sub domain delegated. DNS are handed off to GNS using multicast Domain Name Service m. DNS. included within the Oracle Clusterware. Using GNS eliminates the need for. IP addresses and name resolution and is especially advantageous in. While assigning IP addresses using GNS certainly has its benefits and. IP addresses. it does come at the cost of complexity and requires components not defined in. For example, activating GNS in a cluster requires a DHCP server. Oracle RAC. The example Oracle RAC configuration described in this guide will. IP addresses in. To learn more about the benefits and how to configure GNS, please see. Oracle Grid Infrastructure Installation Guide 1. Release 2 1. 1. 2 for Linux. Assigning IP Addresses Manually using Static IP Address The DNS Method. If you choose not to use GNS, manually defining static IP addresses is still. Oracle Clusterware 1. Release 2 and will be the method. Oracle Clusterware networking components. IP address for the node, RAC interconnect, virtual IP address, and. SCAN virtual IP. It should be pointed out that previous to Oracle 1. Release 2. the need for DNS in order to successfully configure Oracle RAC was. It was technically possible although not. IP addresses only. This actually worked to my advantage with any of my previous articles. RAC because it was one less component to. So, why is the use of DNS now a requirement when manually assigning. IP addresses The answer is. Oracle Clusterware 1. Release 2 requires the use of DNS in order to. SCAN virtual IP addresss. In addition to the requirement of configuring. SCAN virtual IP address in DNS, we will also configure the public and. IP address for all Oracle RAC nodes in DNS for name resolution. If you do not have access to a DNS, instructions will be included. DNS server on the Openfiler network storage server. When using the DNS method for assigning IP addresses, Oracle. IP addresses be manually configured. DNS before starting the Oracle Grid Infrastructure. Single Client Access Name SCAN for the Cluster.
