Modify the deployment topology

Use the Deployment Topology page to manage the topology configuration for your IBM-supplied patterns. Managing the configuration can involve adding and replacing nodes, as well as changing the number of cluster members.

Navigate to the administrative console of a dmgr Servers > Deployment Environments > deployment_environment_name > Additional Properties > Deployment Topology.

Use this page to add nodes to your deployment environment, if needed. You can also change the number of cluster members participating in a particular function for each node.

By adding nodes you can increase the overall work capacity of the system.

Use the procedure described in this task to modify the deployment topology in the following ways:

• Before the deployment environment is generated, so that only the deployment environment definition is updated

• After the deployment environment has been generated, as a means to create or delete cluster members

  If the deployment environment has already been generated, then the changes you make to the topology configuration are used to update the number of cluster members for the corresponding deployment environment clusters.

  For example, if you use the Deployment Topology panel to add a node, then the deployment environment definition is updated by that one node and all clusters that are managed by the deployment environment are adjusted by one more cluster member on that node (or the number of cluster members as defined by this panel). This adjustment is made to the topology configuration when you click OK or Apply on the Deployment Topology panel.

Procedure

• Select an objective and perform the associated actions.

  Objective	Actions
  Add node	Select a node from the pull-down list and click Add.
  Change the number of cluster members involved in each function	Type the number in the entry field underneath the columns labeled: Application Deployment Target Messaging Infrastructure Supporting Infrastructure Remember: You must have at least one cluster member assigned for each function.
  Reset number of clusters assigned to each function	If you modified the number of clusters assigned to each cluster type, and you want to reset the parameters to the original value, click Reset
  Remove a node from the deployment topology	For the node that you want to remove, select the check box in the Select column of the table and click Remove

• Click Apply to keep the updates and remain on the Deployment Topology page. Click OK to keep the updates and return to the previous page.

What to do next

Either save the changes or discard them.
