In order to configure the on demand router (ODR) to route
requests to a generic server cluster, you must configure a multi-cluster
routing policy (MCRP) on each ODR. This allows the ODRs in one cell
to send requests to a remote cell if no application servers are available
in the local cell.
About this task
Configure a multi-cluster routing policy (MCRP) on each ODR,
in all cells, in order to configure the on demand router (ODR) to
route requests to a generic server cluster. To configure all ODRs
in each cell, complete the following steps:
Procedure
- Click . $<applicationName> is
optional. If not specified, this rule applies to all traffic sent
to this ODR. If specified, it only applies to traffic destined for
the application with the name <applicationName>.
- For the property name, type MCRP@<thisCellName>$<applicationName>.
- For the property value, type failover@<thisCellName>$<PrimaryDynamicCluster>,<thisCellName>$<GSCName>. This tells the ODR to first attempt to send traffic matching
the multicluster routing policy rule (based on the application name
specified in step 2, if any) to the local dynamic cluster of application
servers within the cell. If none of the local application servers
are available, the request fails over to the specified generic server
cluster (the generic cluster members in the other cell, which then
route the traffic to the application servers within the cell).
