Dynamic routing/assignment using IAssignmentService - External Routing

I'm trying to use external routing to dynamically calculate the approval stages and the participants. I'm trying to control the N number of stages and who the participants should be all dynamically depending on some conditions.
I can't find any documentation on Oracle site except for this: http://docs.oracle.com/cd/E21764_01/integration.1111/e10224/bp_workflow.htm#BABICJIJ but it doesn't go into details.

Thanks for your reply, but i guess i have not been successful in explaining my requirement clearly.
I am not interested in changing the routing pattern at the AQ level using Alter propogation.
My requirement is at one step above this while posting a message to the source AQ queue.
For eg: My Multi consumer table name: Publisher_Table
queues in my Publisher_Table: 1.Pub1
2.Pub 2
3.Pub 3 and so on
I need to post messages on pub1,pub2 etc...however while configuring the AQ adapter for enqueue opertaion i had to hardcode my queue name to Pub1(One among multiple queues created).
My query is whether i can have this queuename as a variable,so that at runtime i can change the target, instead of having to configure multiple aq adapters one for each pub queue.
Thanks

802.1x dynamic vlan assignment using ACS 4.2

Hi
we have 10 switches 2960 configured with 802.1x authentication against ACS server 4.2.
we have 2 vlans configured on the switches for administrator and endusers. the end user vlan id is 10 and the administartor vlan is is 100.
we need to apply the following scenario, if the enduser PC - that is connected to vlan 10 - has an issue and the administrator will login to the PC with the administrator account to fix that issue, the switch should dynamically reconfigure the port with the administrator vlan ( 100 ) .
is the above scenario doable using dot1x with the ACS server?
waiting your replies

Hi,
I have the following scenario
2 bulidings with multiple floor
Each floor should be in different VLAN.
The network should be authenticated with 802.1x and each switch port should be assigned with dynamic VLAN from ACS.
Each
user should be able to connect and roam around between any building.
when ever a user is connecting his laptop to any floor, he should be
made part of that respective vlan. It is not requred to have the same
IP rage to be allocated, but the dynamic VLAN should be based on the
switch port location.
Can
I configure ACS in such a way that, the ACS will allocate dynamic VLAN
for every 802.1x authentication based on the Network Device Group.
Please refer the attached diagram

Cannot use bpws:getVariableData in dynamic assignment using xpath

Hello,
I'm trying to use dynamic task assignment using xpath expression. I have a BPEL variable (collection) that holds a list of users.
Under task assignment I set the following expression (data type- by expression):

5508 and dynamic vlan assignement

Hello,
I'm trying to setup a 5508 to work with dynamic vlan assignement using the same SSID.
I've followed everyting in this document http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a008076317c.shtml
but it doesn't work, every client independent of the RADIUS group is assigned to the same VLAN.
The only difference I have with that document is the [081] Tunnel-Private-Group-ID for which I use a string (nessesary for the LAN switches which use the same RADIUS) instead of a number.
What I see when sniffing the RADIUS traffic, every option is sent correctly to the WLC, from the WLC side and using the debug aaa events enable option I see nothing interesting.
Any ideas?
Thanks
George

A bit more debugging gave me this:
*Oct 15 09:31:28.491: xx:xx:xx:xx:xx:xx Received Tunnel-Group-ID Attribute -- ignoring AES Interface-Name '200' for STA xx:xx:xx:xx:xx:xx.
*Oct 15 09:31:28.491: xx:xx:xx:xx:xx:xx Tunnel-Type 16777229 should be 13 for STA xx:xx:xx:xx:xx:xx
(xx:xx:xx:xx:xx:xx is the client mac address)
It seems that:
1. WLC ignores the [14179\005] Aire-Interface-Name parameter regardless of what the value is (I have tried the vlan number, the interface name etc)
2. the second error is that the tunnel-type 16777229 should be 13. The tunnel-type has the value VLAN as required according to the Cisco document and in general for this to work. Funny thing is that RFC2868 doesn't define a value of 13 but RFC3580 define VLAN as value 13 so again I've set the correct value.
So I don't really know what to do now. I guess I have to open a TAC ticket.

Task assignment adapter - dynamic route to either group or user

I have configured an approval process in design console and I want to be able to dynamically route the approval request to either the target user manager OR a group. I have written logic/code to automatically determine what group or user to route the request to and also to set the key type to either user or group depending on my logic conditions.
This code is executed in a task assignment adapter and set the values for the key type and key depending on the logic.
i.e. the key type would be "user" and key would be the user key for the target user manager, if my logic determines it should be routed to a manager
OR
the key type would be "group" and key would be the group key for the approval group, if my logic determines it should be routed to a group
HOWEVER MY PROBLEM is with assigning the adapter to a process task. I am thinking I would need to have two entries in the Assignment tab of the process task. The first entry has the default rule and I assigned the target type to "group" and include my adapter here.
How do I go about assigning the second entry for target type "user"? Since "Default" is the only rule option and I am not able to use it twice.
I tried to create a rule in the Rule Definition form and create a Task Assignment rule that might do something to check if a task is assigned to "user", so that I can have this as my second rule in the Assignment tab of the process task and if it is true, it would call my adapter that would return the key for the target user's manager.
I DO NOT KNOW what conditions to set in the Rule Element window for the Task Assignment rule. Can someone tell me what to do here OR provide me with a better alternative.

Thanks for all the responses. Approvals are now being routed correctly.
I have a follow-up question though........ I created a process adapter to send notifications to either the target user manager or members of the group that is the approval is routed to.
I have a notification process task as part of my approval process and in its Integration tab, I added my process adapter that sends notifications.
The code for the adapter uses the same logic I described in my original question to determine if the approval is being routed to a user of group. If it is routed to a group, the notification adapter identifies members of the group and sends email to them, this part works fine.
However the problem is when the logic determines it should be routed to the target user's manager. One of the variables of this notification process adapter is username of the target user. Using that username, my code determines who the manager, gets the manager's email address and sends the email. Problem with this is that when mapping variables for process adapters in the Integration tab, in the Map To field, it does not give you the option of mapping to Request Target User, which would have provided me with user attributes of the target user such as the user name. It provides option for the Requester, but my reality is that the Requester is not always the Target User.
Any suggestions for fixing this would be greatly appreciated.

Dynamic Routing Using Query String (SOAP)

Hi Folks,
Does anyone have any examples on how to do a dynamic routing using a query string from a SOAP Adapter. I know how to get the query string but don't know how to map for dynamic routing.
Thanks,
AArhyn.

After some further examination it seems that both calls are picked up by the same interface. In the RWB both the messages are picked up by the MIOS_GetDetails...
How can i fix this?

Dynamic Routing using AQ Adapter

Hi
I am using AQ Adapter to configure my OSB Buisness services to enqueue/Dequeue messages to my AQ queues.
My requirement is to post messages to different Aq queues at runtime without having to reconfigure adapter everytime.
I tried the routing options,It only allows me to change the endpt url which is the Datasource name in aq adapter, but it doesnot allow me to change the queue_name at runtime.
Is there any other way of acheiving dynamic routing for AQ?
Thanks

OSB Dynamic Routing and Transaction Rollback

Hi,
I have implemented dynamic routing to different jms business services.
That's the flow:
1. I have a proxy service which is invoked via a message delivered to a jms queue(XA connection factory), this queue is configured with
Error Destination, expiration policy redirect, redelivery limit 5 and redelivery delay override 100
2. I use a dynamic routing action
<ctx:route isProxy="false">
<ctx:service>
$businessServiceXXX
</ctx:service>
</ctx:route>
where $businessServiceXXX is a variable to hold my target jms business service, its value depends on some incoming inbound headers.
3. if the endpoint is not correct(business service endpoint is dynamic) I catch the error in a Error handler, I raise an Error but :
THE MESSAGE IS NOT REDIRECTED TO THE ERROR QUEUE.
I know I could solve the issue with another approach like an external table to capture(fix) the endpoints, but it won't be so flexible in terms of deployment capability.
Any Ideas ?
Thanks,
T.

Hi Tony,
Tested this in ALSB 2.5 . Transaction rollbacks fine when error in dynamic routing. I am attaching the test JMS proxy we have used for this.
We had XA enabled CF for JMS proxy service and target JMS BS. The dynamic route was configured in route node with no route error handler or service error handler. The test case was to pause the target JMS queue for production. We could see messages rolling back to the source queue and getting redelivered.

Dynamic routing in OSB

Environment: OSB 10.3.1
To avoid manual configuring all published services one-by-one (eg. alter logging), I'd like to implement a generic proxy pattern in OSB. Assume that I have business services at /bs1, /bs2, etc, proxy services at /ps1, /ps2, etc.
What I'd like to achieve is to publish proxy services which routes to the generic proxy first and then reroute to the original proxy service. For this I published eg. /pps1, /pps2, etc all with an Insert action which saves $inbound/ctx:transport/ctx:uri to . in $header and then route to the genericproxy proxy service.
Generic proxy starts by executing common logic in the pipeline (log, etc), then should fetch the original routing information from the header and use dynamic routing to direct the message to the right proxy service (/ps1, /ps2, etc).
Now the questions:
1. is this the right approach to solve the problem of generic configuration of multiple published services in OSB?
2. appearently the uri itself is not enough for dynamic routing - what else do I need to save from the original message?
3. can I construct a <ctx:route><ctx:service..><ctx:operation..> construct with only Insert actions? I'd need a concrete example here accomplishing this.
Thanks.

Well you have to add Route Node to your proxy pipeline and inside it add a Dynamic Routing action.
If you select the Dynamic Routing action you'll see in the Properties view something like:
Service: <Expression>
Here is where you have to define the <ctx:route> element. You can basically paste the text here.
You could also create an XQuery transformation (so you can reuse it later) and invoke it here (with the XQuery Resources tab). But if you're not very familiar with XQuery I'd advise to start with the first option just to see it working.
At first you could also omit the {$proxy} variable and statically specify the service you want to route to. Or you could use an Assign action to define the $proxy (or any name you want to give it) variable. And then once that's working see if you can get the service path from the headers.
Hope that helps

Good CCIE question: Can multiple site-2-site VPNs support dynamic routing protocols?

Hi All,
Was not sure if this should be posted in LAN routing, WAN routing or VPN forums: I have posted here as the VPN tunnels are the limiting factors...
I am trying to understand if it is possible to have dynamic routing between LANs when using site to site VPNs on three or more ASA55x5-x (9.0).
To best explain the question I have put together an example scenario:
Lets say we have three sites, which are all connected via a separate site-2-site IKEv2 VPNs, in a full mesh topology (6 x SAs).
Across the whole system there would be a 192.168.0.0/16 subnet which is divided up by VLSM across all sites.
The inside / outside interfaces of the ASA would be static IPs from a /30 subnet.
Routing on the outside interface is not of concern in this scenario.
The inside interface of the ASA connects directly to a router, which further uses VLSM to assign additional subnets.
VLSM is not cleanly summarised per site. (I know this flys against VLSM best practice, but makes the scenario clearer...)
New subnets are added and removed at each site on a frequent basis.
EIGRP will be running on each core router, and any stub routers at each site.
So this results in the following example topology, of which I have exaggerated the VLSM position:
(http://www.diagram.ly/?share=#OtprIYuOeKRb3HBV6Qy8CL8ZUE6Bkc2FPg2gKHnzVliaJBhuIG)
Now, using static route redistribution from the ASAs into EIGRP and making the ASAs to be an EIGRP neighbour, would be one way. This would mean an isolated EIGRP AS per site, but each site would only learn about a new remote subnet if the crypto map match ACL was altered. But the bit that I am confused over, is the potential to have new subnets added or removed which would require EIGRP routing processes on the relevant site X router to be altered as well as crypto map ACLs being altered at all sites. This doesn't seem a sensible approach...
The second method could be to have the 192.168.0.0/16 network defined in the crypto map on all tunnels and allow the ASAs routing table to chose which tunnel to send the traffic over. This would require multiple neighbours for the ASA, but for example in OSPF, it can only support one neighbour over a S2S VPN when manually defined (point-to-point). The only way round this I can see is to share our internal routing tables with the IP cloud, but this then discloses information that would be otherwise protected by the IPSEC tunnel...
Is there a better method to propagate the routing information dynamically around the example scenario above?
Is there a way to have dynamic crypto maps based on router information?
P.S. Diagram above produced via http://www.diagram.ly/

Hi Guys,
Thanks for your responses! I am learning here, hence the post.
David: I had looked in to the potential for GRE tunnels, but the side-effects could out weight the benifits. The link provided shows how to pass IKEv1 and ISAKMP traffic through the ASA. In my example (maybe not too clear?) the IPSEC traffic would be terminated on the ASA and not the core router behind.
Marcin: Was looking at OSPF, but is that not limited to one neighbour, due to the "ospf network point-to-point non-broadcast" command in the example (needed to force the unicast over the IPSEC tunnel)? Have had a look in the ASA CLI 9.0 config guide and it is still limited to one neighbour per interface when in point-to-point:
ospf network point-to-point non-broadcastSpecifies the interface as a point-to-point, non-broadcast network.When you designate an interface as point-to-point and non-broadcast, you must manually define the OSPF neighbor; dynamic neighbor discovery is not possible. See the "Defining Static OSPFv2 Neighbors" section for more information. Additionally, you can only define one OSPF neighbor on that interface.
Otherwise I would agree it would be happy days...
Any other ideas (maybe around iBGPs like OSPF) which do not envolve GRE tunnels or terminating the IPSEC on the core router please?
Kindest Regards,
James.

Dynamic Routing in OSB 10gR3

Hello All,
I am trying to do a POC of our use-case and wanted to use the Dynamic Routing feature of OSB 10gR3 -
- Create a Proxy which will accept service_id, version, operation and generic input request
- Proxy should do lookup in the Routing Table (XQuery Resource) and based on the service_id as key will provide the service endpoint as -
<ctx:route>
<ctx:service isProxy="true"> {$routingtable/row[logical/text()=$body/ServiceRequest/ServiceId/text()]/physical/text()}</ctx:service>
<ctx:operation>{$body/ServiceRequest/OperationName/text()}</ctx:operation>
</ctx:route>
- Proxy should also carry out the transformation from generic input request to specific as per the operation.
- Proxy should then be able to call the other proxy services (as per endpoint in the routing table) and the specified operation.
Questions -
Is this possible in OSB 10gR3? What service type (WSDL, AnySOAP, AnyXML, messaging) should the generic proxy be? Any alternative to this approach.
So far, I have used ALSB/OSB for simple use-cases and this is more complex so I am seeking information and feedback on this use-case and how to move forward with this use-case.
Thanks,

Thanks mneelapu.
I started this use-case on baby-steps and I tried use the dynamic routing to call the operation on a proxy services
Generic Proxy (using dynamic routing) -----> Proxy ---> Business <----WSDL (Target Service)
Here are the steps in my code -
(1) Created the Proxy ---> Business <----WSDL (Target Service) and tested using the test console.. all works fine.
(2) Created Generic proxy (Messaging Type with xml as input) and I am passing the xml as
<ServiceRequest>
<ServiceId>TestWS</ServiceId>
<OperationName>getStatus</OperationName>
</ServiceRequest>
(3) Created the pipeline pair and in the request pipeline added the stage and -
- assign the Routing Table (as XQuery Resource) to the $routingtable varible
(Routing Table XML looks like - <routing><row><logical>TestWS</logical><physical>/TestSB/TestPS_1</physical></row></routing>)
- assign the XQuery expression
<ctx:route>
<ctx:service isProxy="true"> {$routingtable/row[logical/text()=$body/ServiceRequest/ServiceId]/physical/text()}</ctx:service>
<ctx:operation>{$body/ServiceRequest/OperationName}</ctx:operation>
</ctx:route>
to $routeresult variable
(4) Added the Route Node with dyanmic routing action added the $routeresult in the expression.
I am getting BEA-382612 (Error preparing message for dispatch). I followed the steps as mentioned on e-docs, what am I missing here?

Xquery expression in Dynamic Routing

Hi All,
I need a help.My requirement is as follows.
1) I Have 2 nos of Proxy and Multiple Business Service.
2) First Proxy calling 2nd Proxy and passing the BusinessService Name in user-define Header(only One Header) using Transport Header.
3)2nd Proxy calls the required Business Service using Dynamic routing.
The problem i am getting is when i am using the xpath expression of the header value($inbound/ctx:transport/ctx:request/tp:headers/tp:user-header/@value) in the Dynamic Routing expression
(<ctx:route>
<ctx:service isProxy="false">
{$inbound/ctx:transport/ctx:request/tp:headers/tp:user-header/@value}
</ctx:service>
</ctx:route>) , I am getting some exception.
But if i use Assign node before Dynamic Routing and mention the same xpath of header value to a variable and the variable in the Dynamic Routing expression,I am able to invoke business Service sucessfully.
But my requirement is not to use any Assign Node.
Does any one has any idea what would be the correct syntax of the expression in Dynamic Routing.
Thanks in Advance ..
Thanks
Deba

Well, interesting try. Oracle has suggested to keep a mapping (in a XML or in database) between logical and physical values of destinations, you are trying to route, in OSB itself and to query it at runtime to get the actual value of destination. Please refer -
http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/userguide/modelingmessageflow.html#wp1081507
What error do you get when you directly use the X-Path in Dynamic Routing expression?

Dynamic routing in an extension

I'm planning to use AngularJS to write a Photoshop extension. In Angular, it's possible to change the view based on the route of the web page.
Is it possible to change the route in a Photoshop extension? Has anyone got dynamic views and routing working?

Well you have to add Route Node to your proxy pipeline and inside it add a Dynamic Routing action.
If you select the Dynamic Routing action you'll see in the Properties view something like:

About route expression in Dynamic route to service

Hi all,
in the "Dynamic route to service" action:
<route xmlns="http://www.bea.com/wli/sb/context">
<service isProxy="true">{ $proxyToBeInvoked }</service>
</route>
I use a variable named 'proxyToBeInvoked' to build dynamically what service shoud be called.
Here an example of ''proxyToBeInvoked" variable assignment:
fn:concat('EventBus-', $eventType, '/providers/', $provider, '/resource/', $providerEventType, '-', $provider, '-TransformIntoIPEvent')
I've noticed that if ''proxyToBeInvoked" points to non-existent proxy no error is raised by ALSB and I can realize that something goes wrong only having a look at log files!
Do you know a way to test if variable ''proxyToBeInvoked" points to existent service or a way to add to the <route> expression some extra flag in order to enforce that the related service exists ?
Best regards
ferp

Hello,
I'm surprised you're having trouble with this one. In ALSB 2.5 and 2.6, I get back a fault when this occurs. My proxy that contains dynamic routing does not have an error handler on the route node, only on the proxy level.
I'm using exactly the same xml syntax as you posted, so it doesn't appear to be a difference in flag settings.
This is the fault that I get back:
<fault xmlns="http://www.bea.com/wli/sb/context">
<errorCode>BEA-382000</errorCode>
<reason>Error preparing message for dispatch</reason>
<location>
<node>ProxyName RouteNodeName</node>
<path>request-pipeline</path>
</location>
</fault>
Hope that helps,
Meghan
