We are trying to implement proxy service using WSO2 ESB (4.8.1). The proxy service implementation needs to access wsdls, schemas and xslts.
One option is to put these artifacts in Governance registry. However, we are not planning to connect ESB with database (which is recommended for governance registry). In that case, is there a way I can refer to these files that are residing in the file system along with other ESB artifacts?
Thanks,
You can use the concept call Deployment Synchronizer based on SVN. Deployment Synchronizer provides capability to synchronize deployment artifacts across the nodes of a product cluster.

I'm looking for the advice of how to manually (i.e. without using Runtime Manager - RM) deploy a mule application package on the on-premises Mule cluster. The official documentation suggests using the RM for the purpose either via the gui or cli or api. However, the RM is not available on our environment.
I can manually deploy the package on a single node by copying it to the /apps folder. But this way the application is only deployed on a single node, not on the cluster.
I've tried using the AMC agent rest API for the purpose with the same result - it only deploys on a single node.
So, what's the correct way of manually deploying a mule application on the Mule servers cluster without using Anypoint RM?
We are on Mule 4.4 EE.
Copy the application jar file into the apps directory of every node. Mule clusters do not transfer applications between nodes.
Alternatively ou can use the Runtime Manager Agent instead however it also works in a per node basis. You need to send the same request to each node to deploy.
Each connector may or may not be cluster aware. Read each connector documentation to understand how they behave. In particular the documentation of the VM connector states:
When running in cluster mode, persistent queues are instead backed by the memory grid. This means that when a Mule flow uses VM Connector to publish content to a queue, Mule runtime engine (Mule) decides whether to process that message in the same origin node or to send it out to the cluster to be picked up and processed by another node.
You can register the multiple nodes through AMC agent on the cloudhub control plane and create a server group and deploy code through control plain runtime manager it does the job of deployment to same app in n nodes
I am working with Mule ESB and instead of using Mule Management Console (MMC). I just want to load balance so that if I am exposing my Mule ESB as a Service so in that case I don't want to use load balancer to balance my Mule ESB , because once the request will come Load Balancer, it is the single point of failure in case if it is down. So I just need a use case how to Expose Mule as a Service with Optimized Load Balancing without using MMC (Mule Management Console).
For load balancing incoming HTTP request, over multiple Mule instances, you will need a external loadbalancer. Mule ESB Enterprise Edition nor MMC will help you with that.
You can use a commercial one, such as a F5 BIP-IP, or setup a HAProxy. To avoid the loadbalancer to be a single point of failure you can setup a redundant HAProxy.
For JMS make sure to setup a external message broker cluster and connect to it using the normal jms:inbound-endpoint that way Mule will act as a competing consumer and you will achieve load balancing of messages.
I would also advice you to have a look at "MuleSoft Blueprint: Load Balancing Mule for Scalability and Availability" that covers this. It is a bit dated but most of the information in there is still valid.
It's unclear what transport are you using, anyhow you have just limited number of options.
Use Mule EE clustering feature for the VM transport.
Use a load balancer
Use a transport that support competing consumers like JMS or AMQP.
Could you provide a more detailed explanation of you deployment so I can provide more extact info?
We create and publish a service through the web console (/publisher). This is environment is a 2 node WSO2 AM cluster with a loadbalancer on top of it (HAProxy).
When we invoke the service (SoapUI), via this load balancer, one request succeeds and the next one fails and so on.
IMHO: The cluster configuration should be correct. I can see the published service on both nodes if I start the /publisher app on each node.
axis2.xml:
- Hazelcast clustering is enabled
- Using multicast
master-datasources.xml
- pointing to Oracle database
api-manager/xml
- pointing to jdbc string in master-datasources.xml
Does anyone have some tips.
It seems that the Synapse Artifact is not deployed on two Gateways correctly. Can you go to /repository/deployment/server/synapse-config/default/api and see if the both node have an xml file for the published API. If you haven't enabled Deployment Synchroniser the artifact will only be created in one node.
I am trying to write scripts(using java) to deploy my mule application on top of the cluster. So that, application get deployed on the Mule ESB servers under cluster.
Already I have written a code to deploy my mule application on Mule ESB server using MMC Rest API(http://www.mulesoft.org/documentation/display/current/MMC+REST+API)
Now my next target is to deploy application on MMC cluster.
Can any one please suggest me a way to deploy mule application on cluster from java code(using API).
Thanks in Advance.
The MMC REST API allows to deploy to a cluster the same way as you deploy to a standalone server:
http://www.mulesoft.org/documentation/display/current/Deployments
Instead of Java code ... why don't you try Maven ... Maven Script directly create application zip and deploy to mmc cluster ... All you need to write the script in .pom file instead of java class
There is a maven plug in that you can use to deploy via MMC:
https://github.com/NicholasAStuart/Maven-Mule-REST-Plugin
mule-mmc-rest-plugin:deploy
This will:
delete an existing mule application archive from the MMC Repository if version contains "SNAPSHOT"
upload the mule application archive to the MMC Repository
delete an existing deployment having the same application name
create a new deployment this the uploaded archive, with target the
given serverGroup
perform a deploy request to make MMC deploy into target server group
I used it and it works (but you may need to make it some customizations)
We have more than 5 corporate applications running on different servers with technologies like spring, struts communication between these application is point to point. We are planning to migrate this to ESB using Mule.
I didnt quite understand how mule works i have few doubts,
Mule is running in a different server do i need to deploy all my 5 aplications into the mule server.
I have spring application delployed on a tomcat server how this application is going to receive messages through mule or what are the configuration changes i need to do in my server or mule server.
Any advice or tutorials.
You need not deploy all you 5 applications in the Mule Server.
You said that all your application are currently point to point (which means that all are talking/communicating now through http protocol), similarly you can also use mule's http endpoints to communicate with all the 5 applications.
I.e. the spring application talking to another spring application can be modified to Spring application talking to Mule and Mule in turn talking to another Spring application .
You must learn the basics from the Documentation
http://www.mulesoft.org/documentation/display/current/Mule+Fundamentals --> browse through the navigation on the lefthand side.
Mule is an integration tool. you no need to change any of your existing applications. All you need is to develop an mule application which can do the mediation/orchestration.
For connecting with your spring application you no need to change any configuration you need to use http:outbound connector inside your mule flow
Just go through http://www.mulesoft.org/documentation/display/current/HTTP+Transport+Reference
So mule is based on SOA principle, so your 5 corporate service need not to be their in a single system. so if you want to consume the service/functionality of any of your 5 application, expose those service as web service, cloud be soap or rest. And you can call those service inside your mule. so in this case you have to create only 5 connection and where ever required you can refer to those connection inside mule configuration file.
#saravanan shanmugavel you need to use Mule ESB to orchestrate the communication between these application...ESB came into the picture to remove your point to point communication...you can create a proxy service for each of your service and one flow which will orchestrate communication between all...
All you need to do is change the application that is configurable according to mule server.
Please refer below link that will be helpful for understanding of mule that helps you better orchestrate communication between all.
