Dynamic routing mediator running continuously

Using Dynamic routing mediator i called a BPEL process but after calling the target BPEL process instance of the Dynamic routing mediator composite running continuously.
Why is it happening?
how we can send callback data to source from Mediator?

Hi,
How are you planning to design your composite ? Right now system B uses Version 1, so you will be adding transformation for Version2 to Version 1.Once your System B is upgraded then it will have to consume Version2 of xsd, for which you have to remove the transformation from mediator and update your webservice with schema 2. In that case you have to redeploy your code.
Are you planning to use BPEL after mediator, or directly you would be calling system B using mediator as standalone component?
How much differenc is between version 1 and version 2 schemas structure wise? Are both of them altogether different ?

Karan

Dynamic route determination run

Hi friends
I am very new to scm, ned help in understanding the following details.
when we enter Scedule optimization run detail by entering job name and profile details we get screen having the buttons immediate/date-time/after job/after event/ at operation mode
Each button has their individual fields to be entered.. for example if I click immediate i get the check box Periodic job and push buttons for Periodic values and restrictions.
Can any one explain in brief or give me link/s which can explain the importance of each button and their related fields.
Regards
Samuel

Hi Samuel,
Are you talking about SM36/SM37.
If yes, then you need to select below mentioned option by you "immediate/date-time/after job/after event/ at operation mode".
You have to finalize which mode you want.
If immediate then the job starts and active once you saved it.
If you saved on date-time based,then it will active on that particular time.
Like that you can set it after any job or any event,then you need to give the job or event name.
Hope it clarifies if I am able to get your question correctly.
Thanks,

Mediator dynamic routing

Hi,
has anyone implemented mediator dynamic routing successfully (11.1.1.5)?
when trying to do it, none of the rules is selected, and when creating a function to test it on jdeveloper it returns an error :
oracle.rules.sdk2.exception.SDKException: RUL-05016: The Java class "oracle.tip.mediator.rules.model.ObjectFactory" cannot be loaded. Ensure that the class and all its dependent classes are on either the class path or the user-specified path.
The error message on the instance is:
Non Recoverable Business Fault :
Fact not found in the rule engine working memory, rule session execution failed. The rule session 771038 failed because an instance of the fact oracle.tip.mediator.rules.model.DynamicRouting could not be found in the working memory of the rule session. This is most likely a rule modeling error. The decision service interaction expects the fact instance to exist in the working memory of the rule session. Check the rule actions in rule designer and make sure that a fact of the expected type is being asserted. If the error persists, contact Oracle Support Services. 771038
Any help?
Regards.

Problem in dynamic routing through ESB

Hi All,
I am trying dynamic routing through ESB, So I created routing service in my esb with WSDL of BPEL Process1 and a soap service with same wsdl. Then created a xsl transformation. In this xsl transformation I added below code to route to BPEL process 2.
<xsl:variable name="LocationIn"
select="http://PC-HP249:8888/orabpel/default/SyncBPELProcess2/1.0/SyncBPELProcess2"/>
<xsl:variable name="LocationOut"
select="ehdr:setOutboundHeader('/shdr:ESBHeader/shdr:location',
$LocationIn, 'shdr=http://xmlns.oracle.com/esb;')"/>
But when I am invoking this ESB through another BPEL process, Got below error message:, Is there any solution for that , I am using 10.1..3.4.0, (JDEV, and BPEL).

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 error

Has anyone had any success with Dynamic Routing on SoaSuite 11.1.1.6. Either through a mediator or through a BPEL Phase activity?
This has been posted previously but I haven't seen a solution yet
The error I get is
Non Recoverable Business Fault :
Fact not found in the rule engine working memory, rule session execution failed. The rule session 210165 failed because an instance of the fact oracle.tip.mediator.rules.model.DynamicRouting could not be found in the working memory of the rule session. This is most likely a rule modeling error. The decision service interaction expects the fact instance to exist in the working memory of the rule session. Check the rule actions in rule designer and make sure that a fact of the expected type is being asserted. If the error persists, contact Oracle Support Services. 210165
The FMW Guide http://docs.oracle.com/cd/E15523_01/integration.1111/e10224/bp_two_layer_bpm.htm#CDEDBJBJ references a sample called BPELPhaseActivity but I can't find this sample
Cheers
Owen

As Hisaak mentioned, try routing option if you want to set URI dynamically. To use the dynamic route action, you need the fully qualified name of the service in Oracle Service Bus as described in http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/userguide/modelingmessageflow.html#wp1081507

Dynamic Routing with VPN and multiple Peers

I have several sites that connect to my primary host site (ASA5525-X) via LAN to LAN tunnels and currently all internal host routing is static. I need to implement a backup host site (ASA5520) for the remote sites to connect to. I know that I can add additional peers on each remote site for the host sites. However, I need to be able to do dynamic routing, so that if does not matter which site they are connected to the internal networks will learn where to route the traffic. I am running OSPF on my internal networks at both Primary and Backup host sites and they have an internal connection between the two sites.
Is there a way to accomplish this on the ASAs?
Thanks,
Doug

To make perhaps my question a little more clear, this is an example of how I would the result to look like
http://www.latitudes.co.uk/dept_search_pages/search_provence.php
where the labels with the checkboxes are retrieved from the 'category' table and when one or more boxes are ticked, the corresponding values are used to make the selection in the WHERE statement in the MySQL query.
Hope someone can help me out.

Dynamic Routing for Failover L2L VPN

Hi,
Can someone offer me some guidance with this issue please?
I've attached a simple diagram of our WAN for reference.
Overview
Firewall is ASA 5510 running 8.4(9)
Core network at Head Office uses OSPF
Static routes on ASA are redistributed into OSPF
Static routes on ASA for VPN are redistributed into OSPF with Metric of 130 so redistributed BGP routes are preferred
Core network has a static route of 10.0.0.0/8 to Corporate WAN, which is redistributed into OSPF
Branch Office WAN uses BGP - Routes are redistributed into OSPF
The routers at the Branch Office use VRRP for IP redundancy for the local clients default gateway.
Primary Branch Office router will pass off VRRP IP to backup router when the WAN interface is down
Backup BO router (.253) only contains a default route to internet
Under normal operation, traffic to/from BO uses Local Branch Office WAN
If local BO WAN link fails, traffic to/from BO uses IPSec VPN across public internet
I'm trying to configure dynamic routing on our network for when a branch office fails over to the IPsec VPN. What I would like to happen (not sure if it's possible) is for the ASA to advertise the subnet at the remote end of the VPN back into OSPF at the Head Office.
I've managed to get this to work using RRI, but for some reason the VPN stays up all the time when we're not in a failover scenario. This causes the ASA to add the remote subnet into it's routing table as a Static route, and not use the route advertised from OSPF from the core network. This prevents clients at the BO from accessing the Internet. If I remove the RRI setting on the VPN, the ASA learns the route to the subnet via the BO WAN - normal operation is resumed.
I have configured the metric of the static routes that get redistributed into OSPF by the ASA to be higher than 110. This is so that the routes redistributed by BGP from the BO WAN into OSPF, are preferred. The idea being, that when the WAN link is available again, the routing changes automatically and the site fails back to the BO WAN.
I suppose what I need to know is; Is this design feasible, and if so where am I going wrong?
Thanks,
Paul

Hi Paul,
your ASA keeps the tunnel alive only because that route exists on ASA. Therefore you have to use IP-SLA on ASA to push network taffic "10.10.10.0/24" based on the echo-reply, by using IP-SLA
Please look at example below, in the example below shows the traffic will flow via the tunnel, only in the event the ASA cannot reach network 10.10.10.0/24 via HQ internal network.
This config will go on ASA,
route inside 10.10.10.0 255.255.2550 10.0.0.2 track 10
(assuming 10.0.0.2 the peering ip of inside ip address of router at HO)
route outside 10.10.10.0 255.255.255.0 254 xxx.xxx.xxx.xxx
(value 254 is higher cost of the route to go via IPSec tunnel and x = to default-gateway of ISP)
sla monitor 99
type echo protocol ipIcmpEcho 10.10.10.254 interface inside
num-packets 3
frequency 10
sla monitor schedule 99 life forever start-time now
track 10 rtr 99 reachability
Let me know, if this helps.
thanks

Dynamic Routing Gateway and ASA

Greetings,
We have a requirement to configure a multisite gateway and have run into an issue. According to http://msdn.microsoft.com/en-us/library/azure/dn133793.aspx, dynamic routing gateways are not supported on the ASA platform. Does this simply mean that MS does
not support this configuration or that this configuration is not possible? I cannot negotiate an ikev2 proposal with a dynamic gateway so I fear that it isn't possible.
Has anyone here made this work?
Thanks in advance.

Hello
In the link you provided, the combination of ASA with dynamic routing says it is not compatible (it does not say not supported).
From that I understand that it will not work.
We have tried a few Juniper combinations in the past with static and dynamic routing that were not on the list you mention - only to find out that they indeed did not work.
My recommendation is to stick to the supported setup.

Dynamic routing protocols over wireless.

Hello all,
Are there any issues with running dynamic routing protocols through two access points (1240AG) bridging two LANs that are presumably currently setup with a dynamic routing protocol?
Thanks,
Patrick

There shouldn't be.
They are acting as bridges ... so no need for a routing protocol in the common broadcast domain.
Unless you have some flavor of broadcast / multicast control in-place, it should pass the traffic without issue.
Good Luck
Scott

Dynamic Routing Protocols - what do I really need to know?

Ok, ridiculously broad question I know but....what I'm trying to figure out is, let's say I'm in a large coproration and I have multiple field sites in different areas of the country so the network setup may be somewhat complex but when it comes to setting up the dynamic routing...is it as simple as let's say, configuring a router to use BGP for whatever portion you designate then just letting it be? is it somewhat challenging to initally configure dynamic routing protocols (i.e. how often have you found yourselves worrying about admin distance, areas (I don't even know what an "area" is yet either so if anyone could explain that I would appreciate it), etc..
So in short, are dynamic routing protocols "Set it and forget it" or do they require a ton of planning to setup? I'm familliar with the differences between them (i.e. OSPF, RIP, EIGRP,etc..) and the differences in link state and distance vector but I just wanted to ask about the setup of the protocols themselves.
Thanks!!

You can exchange routes between protocols with redistribution.
The problem with the question is, as you say, it is too broad to really answer properly.
All routing protocols have different considerations so what you might do for EIGRP you may not do with OSPF and BGP is different altogether.
As a general answer if you are enabling it across a WAN all take a certain amout of planning and design and they all rely heavily on what you have done with your IP addressing in terms of summarisation etc.
The actual configurations to get a basic setup running are relatively simple, certainly for IGPs, but as your network grows you may find the configurations becoming more complex
BGP is a very different in that there are many different commands you can use to influence the path traffic takes but even here to setup a very basic BGP peering only requires a few commands.
But no routing protocol in a large environment should just be configured with no thought as to how it is going to work, traffic paths, number of routes etc.
You can do it but you may well find as your network grows you will end up having to revisit the whole thing because it is not working as you intended.
Like I say it's too large a question to really answer because each routing protocol is different and may or may not meet the requirements of the network.
If there are more specific questions then please feel free to ask.

Dynamic Routing in BPEL 11g

Hi,
I have requirement where i need to dynamically call different WSDL with related xsd's. Currently i have two target system & i have two xsd's. But in future suppose third taregt system will come in picture than i need to change configuration & code will work without changing & deploying original code. Is this possible in BPEL? If yes, could you please provide tutorial related that.
I heard that using mediator we can achive that but i could not able to find any docs for dynamic routing using mediator.
Thanks

Hi,
I had dealt with dynamic routing in BPEL not sure about mediator though.

We have 10 OSB services define on OSB side(let's call them OSB Services), which includes:

https://OSB_host:OSB_port/getDocumentList
At OEG side, we are thinking of 10 OEG service defined as the entry points to 10 OSB services(1:1 mapping between OEG services and OSB services), OEG services exposed to client, including:
https://OEG_host:OEG_port/getDocument (will be route to https://OSB_host:OSB_port/getDocument)
https://OEG_host:OEG_port/getDocumentList(will be route to https://OSB_host:OSB_port/getDocumentList)
But for the policies of processing each OEG service - actually they are much similiar, all following procedure:
1) Message decryption
2) Write log
3) Routing to OSB Service
4) Write log
So we were thinking of just develop one common policy(maybe a global policy?) for 10 OEG services, may I have the idea about HOW could I do dynamic routing to different OSB services in a common policy ?
Thanks.

Your approach sounds right, certainly having a 1:1 mapping between virtualised service in the OEG and the OSB makes things simple.
Place the decryption and logging the global request policy
Have the WS-Filter run as normal to do XSD and routing
Place the logging of response in a global respone policy

PE-CE Dynamic routing

I am running a PE-CE vpn routing. Now my client wants to access a particulat ip which is on internet and may be the demand can be increased and he doesnot want to add the addtional static routes for this. Can we have any routing solution which can solve the purpose. Please post your comments.

Hi Shivlu,
What i understand is, This is an VPN customer and you running dynamic routing protocol (RIPv2/OSPF/EIGRP/BGP) as PE-CE, the customer want to access specific destination address on the internet (google.com) for example, so now we talking about how to make this route reachable through the customer VPN, i think Route Leaking in MPLS/VPN will solve your issue, but in this case you should consider the customer address space issue, i mean how the customer private routes will talk to internet destination, there is a NAT device should be in the path to NAT the customer private address.
This is a very simple URL by Cisco explaning MPLS Route Leaking:
http://www.cisco.com/en/US/tech/tk436/tk832/technologies_configuration_example09186a0080231a3e.shtml
In this case you will add 2 static routes on your PE and redistribute it by the customer PE-CE routing protocol.
Correct me if i didn't get your point
