Platform-specific Considerations

There are small differences in the implementation of Clusters on the various operating systems where Failover Clusters is supported. The following sections note important differences.

Adding Nodes Where the Database Can Be Run For AIX

By default, the resource group is enabled to run ONLY on the current node, the node that was used to enable the database. You change the priority and the number of nodes the database can run on through the SMIT menu, using the smit hacmp fast path command. From this menu, choose Cluster Configuration->Cluster Resources->Define Resource Group->Change/Show a resource group. The Change/Show a resource group option provides a menu where you can change node selection.

After adding the nodes to the resource group, ensure that the directory and its contents for the resource group are copied to the other nodes on where the database is enabled to run. The directory of the resource group is located under /etc/cluster. The name of the directory will be the name of the resource group. The directory and its contents must be in the same location on all nodes.

Upper Limit On the Number Of Packages For HPUX 32-bit and 64-bit

There is an upper limit on the number of packages that can be registered with the cluster manager. One package will be associated with the database. The Watch Dog, BIW, AIW, and every APW will each be associated with an additional package. For example, if the database is enabled as a cluster resource along with an AIW, a BIW, a WDOG, and three APWs, a total of 7 resources will be registered with the cluster manager. PROCLUSTER allows for the creation of files and directories necessary for registration even if the limit is exceeded. It is important to review your configuration details and verify that the maximum number of packages for the cluster will not be exceeded prior to enabling the database as a cluster resource.

If you exceed the limit, adjust the MAX PACKAGE LIMIT, and you can then fix your database resource using one of the following methods:

Directory Of registered packages For HPUX 32-bit and 64-bit

Under the directory /etc/cmcluster, you will find a directory for each package that is registered with the cluster manager. In this directory you will find three files:
