You must configure the node computing power if you are using speed
factor or work factor overrides to configure your multiple tier configuration.
Before you begin
Configure work factor or speed factor overrides. See
Configuring speed factors in multiple tier configurations
and
Overriding work factor estimates
for more information. You must know which
kind of node you 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 that is 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. You cannot define custom properties
for nodes that are not managed and not unmanaged.
About this task
Define node computing power when you are using speed factor or work
factor overrides to define your multiple tier configuration.
Procedure
- If your node is managed or unmanaged, specify the node speed using
the node.speed custom property.
- In the administrative console, click System administration
> Nodes >node_name> Custom Properties > New.
- Enter the Name as node.speed.
- 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 your node is not managed and not unmanaged, configure the external.placement
custom property. For more information about the external.placement
custom property, see Autonomic request flow manager advanced custom properties
.
- 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 that is 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, you 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
- Using 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 you created to define
the external nodes.
