Figure 11-1 depicts active-active configuration in Sun Cluster 3.0.
In Sun Cluster 3.0, Adaptive Server runs as a data service and is managed by the Sun Cluster’s Resource Group Manager (RGM). Adaptive Server is associated with a resource group which contains the Adaptive Sever resource and all other resources it requires, such as the SUNW.HAStorage, SUNW.HAStoragePlus, and SUNW.LogicalHostname resources.
SY.ase is the resource type of the Adaptive Server resource and it defines various extension properties for the resources of type SY.ase. See “Adaptive Server Resource extension properties” for more information. See Sun Cluster 3.0 documentation for more information on standard resource properties.
Figure 11-1: Sample Sun Cluster resource group configuration
In this figure, there are two resource groups, rg_MONEY1 and rg_PERSONNEL1, corresponding to the companion servers MONEY1 and PERSONNEL1 in symmetric configuration.
rg_MONEY1 consists of three resources: ase_MONEY1 of resource type SY.ase, has_MONEY1 of resource type SUNW.HAStorage, and lh_MONEY1 of resource type SUNW.LogicalHostname. The storage resource has_MONEY1 manages the global file system /global/node1_share on the shared disk and the logical host resource lh_MONEY1 manages the logical host name or floating IP address loghost_node1. The Adaptive Server resource ase_MONEY1 depends on has_MONEY1 and lh_MONEY1.
rg_PERSONNEL1 consists of three resources: ase_PERSONNEL1 of resource type SY.ase, has_PERSONNEL1 of resource type SUNW.HAStorage, and lh_PERSONNEL1 of resource type SUNW.LogicalHostname. The storage resource has_PERSONNEL1 manages the global file system /global/node2_share on the shared disk and the logical host resource lh_PERSONNEL1 manages the logical host name or floating IP address loghost_node2. The Adaptive Server resource ase_PERSONNEL1 depends on has_PERSONNEL1 and lh_PERSONNEL1.
