Configure node computing power

Configure the node computing power if we are using speed factor or work factor overrides to configure a multiple tier configuration.

Configure work factor or speed factor overrides. See configuring work factors in multiple tier configurations and overriding work factor estimates. We must know which kind of node we are configuring:

• A managed node is a node with an application server and a node agent that belongs to a cell. Managed nodes can have custom properties defined.

• An unmanaged node is a node defined in the cell topology that does not have a node agent that manages the process. An unmanaged node is typically used to manage Web servers. Unmanaged nodes are defined in the administrative console and can have custom properties defined.
• A node that is not managed and not unmanaged does not have any information stored in the configuration files. We cannot define custom properties for nodes that are not managed and not unmanaged.

Define node computing power when we are using speed factor or work factor overrides to define a multiple tier configuration.

Tasks

• If our node is managed or unmanaged, specify the node speed using the node.speed custom property.

  1. In the administrative console, click...

             System administration > Nodes > node > Custom Properties > New.

  2. Enter the Name as node.speed.

  3. Enter the Value. The value equals the node.speed in MHz. In a multi-processor node, multiply the processor speed by the number of processors on a multi-processor node.

• If our node is not managed and not unmanaged, configure the external.placement custom property. For more information about the external.placement custom property, read about autonomic request flow manager advanced custom properties.
  1. Compose a string that defines a case for each external node that is not managed and not unmanaged. Each case is separated by a semicolon. Each case consists of information about the node defined in the following pattern:

     nodeName:nodeSpeed:plmtlist
     

     The nodeName variable is the name of the node. The nodeSpeed variable is the speed of the node. The plmtlist is a placement list of deployment targets. Separate the deployment targets with commas. For example, we have the DBA and DBB unmonitored nodes in the SysX cell. The DBA node has a power of 4.7. The DBB node has a power of 2.7. There are two external clusters in the SysX cell that are named DB1 and DB2 . The DB1 cluster is placed on the DBA node only. The DB2 cluster is placed on both the DBA node and the DBB node. Use the following string to define this configuration:

     ../SysX/DBA:4.7:DB1,DB2; ../SysX/DBB:2.7:DB2
     

  2. Use the string that describes the external nodes, create the external.placement custom property. In the administrative console, click...

             System administration > Cell > Custom properties > New. Enter the name of the custom property as external.placement. The Value equals the string that we created to define the external nodes.
