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 in the case that 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
- Servers > On demand routers > ODR_name > On
demand router properties > On demand router settings > Custom
properties > New. $<applicationName> is
optional. If not specified, this rule applies to all traffic sent
to this ODR. If specified, it only applies to traffic destined for
the application with the name <applicationName>.
- For the property name, type MCRP@<thisCellName>$<applicationName>.
- For the property value, type failover@<thisCellName>$<PrimaryDynamicCluster>,<thisCellName>$<GSCName>.
This tells the ODR to first attempt to send traffic which matches
this MCRP rule (based on the application name specified in Step 2,
if any) to the local dynamic cluster of application servers that are
in this cell. If none of the local application servers are available,
it will failover to the generic server cluster specified (which is
the ODRs in the other cell, which will then route the traffic to the
application servers local to that cell).
