OSPF between Multiple MPLS Service Providers

Hi,
One of my customer currently connects to three different MPLS providers. All the SP's PEs are already configured with the customer's subnets, but the CE is configured to point only to one of the PE as the default route. If the link to this SP is down, the customer need to manually change the default route to point to another SP.
How can I enable dynamic routing, e.g. OSPF, to all the of service providers? What is required from the service providers to enable this?
Thanks for all the advice.
rgds,
Arief

A better understanding of the full topology, such as all the branches that this CE is talking to, and via which of the SPs they are reachable via would help.
I do not see much problem, more especiall, if you take the pains to configure the routing protocol on the CE to only advertise the local subnet and not other subnets learnt by it.

Multiple SAML Service Providers

Hello
Is it possible to have multiple SAML 2.0 service providers configured per Weblogic domain or are separate domains required? If it is possible I assume each SP would need its own WL server within the domain. We are looking at ways of using Weblogic to handle saml authentication from multiple apps with each app configured as a SAML 2.0 Identity Provider on ADFS.

Just so you know, having a second AXL service provider is supported by Cisco. Just check out this section of the Installation Guide for UCCX 9x.
In the Cisco Unified CM Configuration window, the Cisco Unified CCX 9.0(1) AXL Service Provider Configuration area for a Unified CM Cluster setup displays a list of IP addresses of the AXL Service Providers sorted by priority, where the Unified CM Publisher is listed first followed by the Unified CM Subscribers. During the AXL Service Provider Authentication in the Unified CM Cluster deployment, the priority is given to the Unified CM Publisher. However, if the Unified CM Publisher is offline or not available, the next available Unified CM Subscriber is chosen for user authentication. You can also change the priority of the AXL Service Providers, if necessary, by selecting the IP address of an AXL Service Provider in the list and clicking the up and down arrow.Note As per the Unified CM design, even if the Unified CM Publisher is listed after a Unified CM Subscriber, the system will use the Unified CM Publisher for authentication. However, if the Unified CM Publisher is offline, the Unified CM Subscriber will use its own database to authenticate.

How to implement redundant with 1 CE router to 2 MPLS service providers

Dear all,
Our head-office are currently have 1 Cisco CPE 3825 router with 2 WAN connections to our branches. We are now using static routing protocol in our network infrastructure, we consider how to implement the redundancy for networks by the redundant circuits connection to 2 MPLS providers, only when the primary connection to the primary MPLS L3 provider fail, the backup link to the second MPLS Layer 2 provider automatically active. Anybody knows where can I find information, tips or examples, how we'd handle the routing for that?
We are now have:
1 G0/1 interface connect to primary MPLS L3 Provider (the 2nd G0/2 interface is a leased-line connection to our partner, and we not consider here)
1 HWIC (layer 2) card, with 4 ports, which has interface F0/2/3 connected to the backup MPLS Layer 2 provider.
Thanks in advance.

Hi Mr jianqu,
Because of our customer now has 2 main central offices, and all other sub branches are now connected to each of these main central office via one primary full-meshed MPLS VPN of 1st Service Provider, so If I use the float static routes, and when there is a failure at one link at a CENTRAL CE Router to primary link to primary MPLS VPN Service Provider, but still there is no failure at the other site from a router CE sub branch with the the PE of the primary full-meshed MPLS VPN Layer 3 Service Provider,so It cannot cause a failover to a second redundant link of the 2nd Service Provider?
So with our system, do we only have one solution like this:
-Configure BGP as the routing protocol between the CE and the PE routers.
-Use local preference and Multi Exit Discriminator (MED) when running BGP inside a our customer VPN to select the primary and backup links.
-Use AS-override feature to support overlapping AS numbers between customer sites

MPLS Service

Hi,
I would like to know how everyone does their MPLS design. Ideally, you put all sites on one single MPLS service provider, e.g. ATT, with single access link. Data centers will have two access links for redundancy.
However, what if I want to have two MPLS service providers, put half of the sites on one MPLS cloud and another half on the second MPLS cloud? How would you do the routing between them? ATT stated that they would not exchange routes to another SP. I would like to know if anyone has two MPLS SP and how they do it.
Thanks.

Kevin,
What we do is terminate the one Service Provider on one router, and then terminate the other service provider on another and share routes between the two routers through your own infrastructure.
This isn't the only design but one that we have implemented.

How to control transactions (WS-AT) between two web services in OSB?

Could someone tell me if the OSB can have 2 diferents web services controlled by an unique transaction?
For instance: in the OSB there are two wsdl, each one with its own Business Service and ProxyService respectively. In my vb.net aplication I started a transaction, called the first web service succefully and from the second web service I got an exception. I expected the first web service undo its work because the vb.net aplication excute a rollback command. Is this possible? How can I do? Any sample or tip will be helpfull.
If I was developing without OSB, I would rely on WS-AT as shown in http://www.codeproject.com/Articles/38793/6-Steps-to-Enable-Transactions-in-WCF for two web services dot net, or for one web service dot net and other java, http://www.ibm.com/developerworks/websphere/library/techarticles/0707_lo/0707_lo.html.
My question is basically: Is still possible to keep a single transaction between multiple web services when they are mediated by OSB? If so, is there a example showing how?

Hi,
When you create the proxy server, you have to check "Transaction required" box on Message Handling page...

Load sharing/balancing between 2 Service Providers

Hi,
I have a scenario where I have the following and this is repeated at different sites globally.
CE1-----------PE1_SP1---MPLS cloud
|
CE1---standby--PE2_SP1---MPLS cloud
CE2-----------PE1_SP2----MPLS Cloud
|
CE2---standby--PE2_SP2---MPLS Cloud
2 different service providers and we require load sharing/balancing to both SP1 and SP2.
If either of the SP's PE router is down it should bring up the standby link.
2 ASN, not sure if I can load share different prefixes in this scenario.
Will the applications fail?
Will the traffic flow be symmetric ?
Any help is very much appreciated.
Thanks,
Paul

Hello Paul,
if you are using a single CE router on each site.
to get load-balancing on your CEx:
router bgp X
maximum-paths 2
eBGP load-balancing is easier so 2 ISP ASN is fine
Verify that you have flow based load-balancing and everything should be fine.
Notice that you have a failure on site N of provider1 you can be able to detect it in all remote sites only if they are receiving the routes of all the sites. If receiving a default route there's no way for other sites to detect the failure.
If receiving all the prefixes after MP-BGP convergence in ISP1 site N's prefixes will be withdrawn and will be reachable only via ISP2.
To use an active/standby
on all Cex
router bgp x
neighbor PE-ISP1 weigth 500
neighbor PE-ISP1 fast-external-fallover
in this way until a prefix is present in ISP1 MP-BGP traffic is sent via ISP1
If using two CE in each site things are a little more complex and you need an iBGP session between them.
Hope to help

Share Data Source between multiple report projects in Microsoft SQL Server 2012 Reporting Services

I have a reports solution in 2012 which contains multiple report projects one each for target deployment folder and we use TFS 2012 for report deployment.
We have a template project which has a bunch of template reports and all the datasources used in different reports.
When I develop a report, I cannot "Preview" in TFS but, for deploy this used to work fine util the reports solution was in TFS 2010 & Visual Studio 2008 R2. Since we moved to TFS 2012 & SSRS 2012 not being able to deploy till I create all
the necessary datasources for each project and now all the developers complaining that they cannot develop reports in TFS itself as they cannot preview (this problem was existing previously) and now not being able to deploy as it errors for each report "Could
not find specified rds file". I tried messing around with the .rptproj file DataSources tag that did not help either by modifying it like below.
<DataSources>
<ProjectItem>
<Name>DB.rds</Name>
<FullPath>Template\Data Source\DB.rds</FullPath>
</ProjectItem>
</DataSources>
Is there a way I could share a Data Source between multiple projects in Microsoft SQL Server 2012 Reporting Services?
Thanks in advance.............
Ione

Hi ione721,
According to your description, you want to create a shared data source which works for multiple projects. Right?
In Reporting Services, A shared data source is a set of data source connection properties that can be referenced by multiple reports, models, and data-driven subscriptions that run on a Reporting Services report server. It must be within one project.
We can't specify one data source working for multple projects. In this scenario, we suggest you put those reports into one project. Otherwise you can only create one data source for each project.
If you have any question, please feel free to ask.
Best Regards,
Simon Hou

IMessage issue between different service providers?

I am having problems with sending/receiving iMessages between different service providers. If you start an iMessage conversation on an iPad2 you're supposed to be able to continue it on an iPhone 4s or other ios 5 device, but it only does so if I iMessage to someone who also has AT&T, not Verizon.

Thank you. However, phone numbers work between AT&T as I have successfully done so on many occasions. I will try email addresses for iMessages to Verizon and Sprint users to see if that my problem.

What's the difference between Routing and Service Callout in ALSB?

I am puzzled by that.
what's the difference between them.
Or what's the situation should use Routing, and that of service callout?

There is little difference between routing and service callout.
Routing is symbolizes the transition of request thread to a response thread starts. (in OSB every invocation of proxy is undertaken by different request and response threads ). So by this definition, there can be only one route node in a pipeline.
Service call out is also used for similar actions as route node , but in pipeline. So service callout can be either in request pipeline (request thread) or in response pipeline (response thread ) . So in a proxy you can have multiple ServiceCallouts but only one route node.
There are some other slight differences.

Multiple Web Services in one Jdeveloper project

Hi all,
I'm currently trying to implement a series of web services, all relating to one application. I'm using the top-down approach, where I generate the web service from a WSDL file, and add my implementation to the generated classes. The WSDL file imports all sorts of XML Schemas (xsd-files) and Jdeveloper correctly generates all the necessary java-classes for me. Lets call the first web service I create WS-1.
This all works fine and I'm a happy panda. I can call the web service, it works, I can modif the wsdl and regenerate the web service to e.g. change the input etc. All this works.
Just until the point where I want to create a second web service (lets call this WS-2). This new web service doesn't use all the XML Schemas that the first web service does, it is more simple with regards to in-/output. The problem arises when I modify WS-2 and Jdeveloper regenerates the Web service files (.java and the files in the WEB-INF/wsdl-directory). When I do this, it deletes the imported xsd-files that WS-1 uses (removes them from WEB-INF/wsdl).
And when I regenerate WS-1 to get my xsd-files in again, then when I regenerate WS-2 it imports all the unnecessary xsd-files into the wsdl for WS-2.
Something tells me, that there is a connection or shared library between all web services in one Jdeveloper project. That they all imports and uses the xsd-files in WEB-INF/wsdl.
Is this true? Can't I have multiple web services (and wsdl-files) using different types (schema definitions) in the the same Jdeveloper project?
One solution I can think of, is to have all my web services in different projects under the same application. But is this really necessary?
I'm using Jdeveloper 10.1.3.3.0.

Hi,
pure from a coder instinct I think I would prefer them to be in separate projects for better reuse and clean separation. If I need project 1 to access aclass from Project 2, I can check the dependency check box in the project properties. Is there any business requirement that makes you think having all of these in a single project will help ?
Frank
Btw.: I agree that JDeveloper shouldn't constraint developers from doing what they want and if this is a limitation the feel free to file a bug

Failed to retrieve data from the database/invalid argument provided when employing link between two web services datasources

Post Author: vpost
CA Forum: Data Connectivity and SQL
I am trying to join information from two related web services within CR XI. I have successfully set up the web services as data sources have been able to get to the point where I get good data back. However, when I try to pull in certain fields, I get an error that says "Failed to retrieve data from the database/invalid argument provided". Here's the scenario:
The web services are structured as follows:Web Service 1 (Artist) has attributes of Artist Name and Date of Birth.Web Service 2 (CD) has attributes of CD Title and Release Date. Underneath each CD are songs, each of which have a Song Title and Artist Name.
I have defined both web services and defined a link between Artist.Artist Name and CD/Song.Artist Name. I am able to run a report with Song Title and Date of Birth that crosses web services. I am able to run another report with Song Title and CD Title that crosses the different levels in the second web service. However, if I add CD Title to the first report or Date of Birth to the second (both of which effectively force CR to employ the link between the two web services AND the CD/Song hierarchical structure in the second web service, I get the aforementioned error.
Any assistance understanding how multiple web services can be linked in this manner would be greatly appreciated.
Thanks in advance.

Not sure about your exact situation, but having similar problem with another application and have tracked down to security. Added user to group Domain Admin and it works fine. It appears to be accessing a subdirectory which it does not have permission to use and then times out and returns the "invalid....". Seems that once the query just over a certain size (and I'm not sure what triggers this) it needs to make use of temparory file disk, intead of ram.
I'm still trying to track down which temporary it's trying to uses - so if you have any ques.

Difference between a WEB service and a Enterprise Service?

Can Anybody explain me the difference between a WEB service and a Enterprise Service?

Hi Anilkumar K Naidu ,
Web service
A Web service is a self-contained, modularized functionality, which can be published, discovered, and accessed across a network using open standards and which is supported by SAP NetWeaver. Web services cover services provision for integration within an enterprise as well as cross enterprises on top of any communication technology stack, whether asynchronous or synchronous, in any format.
Web Services in the NetWeaver framework play an important role in facilitating the integration of disparate applications from various departments or trading partners and thus increasing business productivity. This benefit allows small and medium businesses also to integrate their business applications with larger trading partners. The benefit derived from this seamless integration introduces security concerns when all the business logic is now being exposed through a standard interface that is a catalyst for security vulnerabilities. SAP Security Managers must use automated diagnostics tools to ensure that the security vulnerabilities are caught in pre-production and in post-production phase.

Enterprise Service-Oriented Architecture (Enterprise SOA)
Enterprise SOA is a blueprint for an adaptable, flexible, and open IT architecture for developing services-based, enterprise-scale business solutions. With SAP NetWeaver as a technical foundation, enterprise SOA moves IT architectures to higher levels of adaptability and moves companies closer to the vision of real-time enterprises by elevating Web services to an enterprise level.
An enterprise service is typically a series of Web services combined with business logic that can be accessed and used repeatedly to support a particular business process. Aggregating Web services into business-level enterprise services provides a more meaningful foundation for the task of automating enterprise-scale business scenarios.

Interfaces with Logistics Service Providers (external WMS)

Hi all,
I am currently in the process of designing possible solutions for our interfaces between SAP and LSP.
We have external 3rd party Logistics Service Providers (LSP) handling our warehouse. LSP has their own WMS system. We don't have WMS configured in SAP. Our warehouse will receive goods from supplier, issue stock to customers and receive returns from customers.
Could you please clarify the following ?
1. What are the preferred ways of sending the messages for e.g. flat file/EDI/XML ?
2. What are the possible messages we need to exchange (say for e.g to have goods receipt / goods issue / stock take / daily stock reconciliation) ?
3. Which one is advisable ?
to send shipping notification (SN) from supplier direct to LSP system and receive GR details from LSP to SAP
(or)
to receive SN from supplier in SAP and send the inbound delivery created in SAP to LSP so that GR can be done based on this ?
4. How can the stock discrepancy / stock reconciliation can be handled between 2 systems on a daily basis ?
5. Is there any website to get more information about the interfaces between SAP and external WMS systems ?
Your advise would be highly appreciated.
Thanks in advance,
anand

Hi Aries,
No problem, I think I have not mentioned clearly. We have different Warehouses (in different countries) managed by different LSPs and each one has got different WMS system. Mostly they are non-SAP system and one is a SAP system with Transport management module. As I said earlier we have only IM configured in our SAP without WMS. Could you please tell what you interface your WMS with 3rd party WMS(SAP system)?
Still I am wondering whether the set up in OMKY can be used for my requirement as it tells about connecting SAP to external non-SAP system ?
Any ideas will be much appreciated,
Thanks,
anand

Multiple MPLS Carriers/Networks

Does anyone have any experience with using 2 MPLS carriers for load balancing. We'd like to have a primary MPLS network with ATT and then a backup MPLS network with MCI. But rather than use MCI strictly for backup we'd like to load balance traffic across both networks. Most of our bigger sites will have a connection into both clouds. Anyone have any idea how we'd handle the routing for that?

I assist in supporting an environment which might almost be identical to that you want to move into.
The first issue you might bump into is the way EBGP will prefer to always use its CE-PE link if it sees otherwise equal paths. Simple solution, divide your traffic to your CEs. We do this either by using GLBP for small sites, or via equal cost paths within the LANs routing topology to the CE routers.
Second issue you might bump into is if the AS topologies are different between the MPLS providers making AS hop counts different between sites. We addressed this issue by defining and maintaining our own logical topology that looks identical between the different MPLS providers.
Both of the prior principally perform static load balancing but if you working with 12.4 or later, you might also want to look at OER. It can dynamically load balance, either with the static techniques, above, or without them.
PS:
We also deal with the situation where two sites are not on the same provider's MPLS. (Usually the result of some problem.) For this, we leak routes between the providers at major hubs permitting traffic to transit between the providers for sites that can not be reached on the same provider.

How can i easy to publish multiple enterprise services

Hi All,
I'm trying to use an enterprise service at multiple clients.
Now, When create a new enterprise service, I create end point and publish service all the time.
If we'd like to use multiple enterprise services at multiple clients,
Do I have to create end point & publish services to each of multiple enterprise services?
(For instance, 3 clients * 10 enterprise services = 30 creates and publishes ??)
Could you tell me an easy way to it.
Thanks
Masahiro

We can achieve multiple enterprise services publishing by configuring Service registry between client server and esr.
