Rules for ODR routing policy administrative tasks

You can use administrative tasks to configure HTTP or Session Initiation Protocol (SIP) rules for the on demand router (ODR) routing policy.

The following rules are the preferred way to configure routing policies, but using the multi-cluster routing property (MCRP) custom property is another option. See the custom properties topic provided in the related links at the end of this topic. The advantage of using the following rules is that an expression can be used to determine which requests are affected by the policy, whereas MCRP custom properties only allow filtering by an application or and application's webmodule. The other advantage of these rules is that you can select the target (routingLocations) by cluster, server or webmodule, as opposed to just cluster.

addRoutingRule

The addRoutingRule command adds a routing policy rule.

Required parameters
-protocol
Specifies the name of the protocol to associate with a rule. (String, required)
-priority
Positive integer value representing the priority of a rule. Zero is the highest priority. (String, required)
-expression
Specifies the rule expression. The expression must be enclosed in double quotes. For more information about specifying the parameters for the rule expression, refer to the SIP operands topic and the HTTP operands topic. (String, required)
-actionType
Specifies the type of action to associate with a rule. (String, required)
The following list contains the types of actions to associate with HTTP rules:
  • permit: Permit routing to servers not in a maintenance mode
  • redirect: Redirect the request to the URL specified by the redirectURL option
  • reject: Reject routing with return code specified by the errorcode option
  • permitsticky: Permit routing to servers not in maintenance mode and perform active affinity; that is, affinity is always preserved even when not requested by the application.
  • permitMM: Permit routing to servers in maintenance mode
  • permitstickyMM: Permit routing to servers in maintenance mode and perform active affinity.
[Version 6.1.0.1 and later] The following list contains the types of actions to associate with SIP rules:
  • permit: Permit routing to
  • reject: Reject routing with return code
Optional parameters
-odrname
Specifies the name of the ODR to which the routing policy work class applies. The -odrname parameter is required only if you modify an ODR.
-nodename
Specifies the name of the node on which the ODR resides. The -nodename parameter is required only if you modify an ODR.
-clustername
Specifies the name of the cluster to which the rule applies. The -clustername parameter is required only if you modify an ODR cluster.
-multiclusterAction
Specifies the method to route requests if multiple routing location clusters are matched. The -multiclusterAction parameter applies to any of the permit actionTypes, and is required only if actionType is equal to permit, permitsticky, permitMM, or permitstickyMM.
  • Failover: Find the first cluster with an available server and load balance across that cluster. The order of a dynamically generated list of clusters is undefined.
  • WRR: Weighted Round Robin load balance. For UDP retransmission, maintain affinity.
  • WLOR: Weighted least outstanding request.
    Best practice: The recommendation is to use the WLOR value instead of the WRR value.bprac
[Version 6.1.0.1 and later] The following list contains the possible values for SIP rules:
  • Failover: Find the first cluster with an available server and load balance across that cluster. The order of a dynamically generated list of clusters is undefined.
  • WRR: Weighted Round Robin load balance. For UDP retransmission, maintain affinity.
  • Error: If there are multiple clusters, to select from it throws an error. it expects one and only one cluster.
-routingLocations
Specifies a list of target locations to route requests. The -routingLocations parameter is required only if actionType is equal to any of the permit actionTypes.
Each operand in the list follows one of three formats, and can contain a wildcard * value, which matches any value:
  • cluster=cellName/clusterName
  • server=cellName/nodeName/serverName
  • module=cellName/applicationName/applicationVersion/moduleName
[Version 6.1.0.1 and later] With SIP routing rules only, you can alternatively define target clusters through a rule expression. The valid operators are AND, OR, NOT and parenthetical grouping. Format according to the following list:
  • cluster=cellName/clusterName
  • server=cellName/nodeName/serverName
  • modules=cellName/applicationName/applicationVersion/moduleName
  • server maintenance mode=true or false
  • node maintenance mode=true or false
  • protocol=PROTO_VALUE:
    PROTO_SIP = sip
    SIP over TCP
    PROTO_SIPS = sips
    SIP over SSL and TCP
    PROTO_SIPU = sipu
    SIP over UDP
    PROTO_SIPX = sipx
    SIP over XMEM
Note: For applications that have no applicationVersion value, leave the applicationVersion value blank: module=cellName/application//moduleName.
-errorcode
Integer error code to reject request. The -errorcode parameter is required only if actionType is equal to reject.

Batch mode example usage

The following example shows a failover of all applications in a cell to a generic server cluster that points to another cell:
  • Using Jacl:
    $AdminTask addRoutingRule {-odrname odr -nodename node1 -protocol SIP -priority 0 -expression "request.method = 'getOperation'" -actionType permit -multiclusterAction Failover -routingLocations cluster=*/*}
  • Using Jython string:
    AdminTask.addRoutingRule('[-odrname odr -nodename node1 -protocol HTTP -priority 0 -expression "request.method = \'INVITE\'" -actionType permit -multiclusterAction Failover -routingLocations "module=*/*/*/*,cluster=myCell/myFailoverGSCThatPointsToAnotherCell"]')
