Page 2: Overview
Overview Oracle® Real Application Clusters (RAC) has a scale out, shared-disk clustering architecture. In a shared-disk architecture, all nodes in the cluster have access to, and can manipulate, the same data set. Concurrent access to the data from multiple nodes is synchronized through a private cluster interconnect network. -

Figure 1. Example high level system diagram Protocols used by Oracle RAC in an InfiniBand environment There are 3 major components in an Oracle RAC cluster that make use of the cluster interconnect: • Oracle Cluster Ready Services (CRS) • Database or ASM instances •... -

Figure 2. Protocols used in an Oracle RAC environment with InfiniBand Internode synchronization in an Oracle RAC environment Because RAC is a shared-disk clustering architecture, the database instances on each node must cooperate in order to maintain the integrity of the data. Database users could potentially attempt to update the same records from different nodes. -

write/write). In both cases, the node that holds the initially updated data block ships the block to the requesting node across the high speed cluster interconnect. In the case of the write/read case scenario, a node wants to update a block that’s already read and cached by a remote instance. -

• Set the host_mode for each connection to Linux. In a redundant configuration, each node in the cluster should have 2 connections, one for each port on the HBA. • If Selective Storage Presentation (SSP) is used to control access to the LUNs, make sure to present the LUNs used for storage by the database to ALL of the nodes in the cluster. - Page 10 Verify that the ib device started successfully by examining the output of the command ifconfig. Output from the command should contain something similar to the following: Link encap:Ethernet HWaddr DD:8B:86:C8:4D:0B inet addr:192.168.0.1 Bcast:192.168.0.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:2044 Metric:1 RX packets:967 errors:0 dropped:0 overruns:0 frame:0 TX packets:1264 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:128...
