I worked over the last weeks with wso2 products using some of the tutorials which were posted on the wso2 site.
Unfortunately I only found tutorials, where all the products run on the same machine.
What do I have to do, if I want to run the products on different machines. I want a configuration where:
- ESB runs on machine 1
- AS and GREG run onmachine 2
- Proxy-services in the ESB or a web servcie in AS are invoked from machine 3
I run these examples on some macs, I think the main problem are the ports which are used. Can somebody help me with the configuration?
Can you elaborate your configurarion problem?
With this configuration you have to be sure that from one server you can ping the another servers and that in each server you have the ports 9443 and 9763 (by default) open to the network. this is the only requirement you need.
What you are trying is nothing new. In a typical production deployment each of the servers run in their own physical/virtual machines.
when you are calling a service, you calling an endpoint uniquely identified by IP address:port/contextPath
If the setup is in the same local machine the IP address would be 'localhost'.
First you have to learn the tcp/ip basics, the question is not related to wso2 servers IMHO.

I’m an absolute beginner when it comes to setting up a Jenkins environment but I have just installed Jenkins on a MAC v10.15.5 using home-brew and would like the capability to:
Open a web browser
Login to Jenkins from any machine on any network
Trigger a job.
I’m able to do this using a different machine on the same network but unable to do this using a machine on a different network. I changed the "httpListenAddress" value within the jenkins-lts.plist file to 0.0.0.0 to allow the web interface to be accessible from anywhere as mentioned at https://www.macminivault.com/installing-jenkins-on-macos/ but apart from that I’m not sure where to go from here.
I’ve heard about Apache Tomcat but not sure if it's necessary for what I need to do. If anyone can provide instructions / safe approaches about how to login to the Jenkins environment on my MAC from any network that would be appreciated.
To get jenkins web interface use $JENKINS_HOST_IP:8080 (by default jenkins uses port 8080) and then make first-run-configure.
Login to Jenkins from any machine on any network - it depends on network topology, what is used in your organisation. So, to reach jenkins host from any network where should be allowed traffic from/into network where jenkins host is placed.
Trigger a job - where are a lot of triggers you can use. Take a look at official documentation here
I am trying to set up my JMeter master/slave set up on AWS EC2 instances using windows. Out of the box integration didn't work (connection refused errors) and after some investigation I got to know that RMI communication only works if the machines are on same subnet (is this true?). I found this great article and I tried to follow it as is on windows (tried running ssh port forward tunneling via cygwin) but not have any luck. So I was hoping if someone already done this with Windows and can share their experience.

It is not necessary. Even if the machines are in a different subnet and addressable via the network, RMI should work. Here make sure the Security Groups and NACLs are properly set so that both EC2 instances can communicate with each other via the network.
You can check whether you can ping(For this you need to enable ICMP in your Security Groups and also make sure other needed ports are opened for RMI) from one EC2 instance to another. If the servers can communicate with each other, then you need to troubleshoot internal firewall configuration in windows EC2 instances.
We have used https://testable.io/ AMI's from the marketplace. It takes care of all configuration and just needs to worry only about testing and the results.
https://aws.amazon.com/marketplace/pp/B073JNTVKP
All our endpoints are secured to certain IP-ranges from testable.io. If you have internal, still you need to setup those security settings.
Hope it helps.
i'm using the WSO2 ESB to integrate several services on the Windows virtual machine.
I used the simple proxy to map the services deployed on it. But the problem is what i can't access them from outside it nevetheless the port 8280 where services are deployed is open for internet, but i can see only blank page instead. What could be wrong?
Another question is i was trying to map the WSO2 ESB management console itself to be availbe from outside the machine using simple proxy, and i'm failed, it loads me the this is what i see on trying the service.
Could you please give me a hint on how to resolve this issue? is it possible to share the esb mgmt console using the ESB itself?
Thanks a lot in advance,
Do u have proxy in the middle? It looks like on screenshot webpage missing all pictures, meanwhile css was loaded successfully.
Another question which kind of virtual machine u use? For example in virtualbox by default virtual machine behind NAT.
I wasn't able to connect to server on virtual machine from host only opposite way server on host available in virtual machine.
To make server in virtual machine available on host need to configure network as bridge.
Not sure if it helps, but I think I had a similar problem in our corporate network after I applied all the security patches (poodle,Diffie-Hellman etc.). I had to configure the addresses in catalina.xml (if i remember right) that are/under which allowed to access the admin console. Cannot tell you more details because I'm on holiday :-)
Maybe it's worth to give it a try.
Another example from real life. HTTP Response from external resource was application/json, status of response 200 OK. ESB configured to use
<messageFormatter contentType="application/json"
class="org.apache.synapse.commons.json.JsonStreamFormatter"/>
but content was simple text/plain.
During parsing body of http response exception was thrown and just silently was written to log, without any fault message processing. Just empty response to client.
To clarify that services reachable, there is echo service by default on server, which respond content equal to request. Try to use it.
was trying to map the WSO2 ESB management console itself to be availbe
from outside the machine using simple proxy
By default the management console tries to enforce the port 9443 for dynamic links (JSP) pages. That's why you see only part of the pages and you shouldn't be able to log on.
what you can do is edit the repository/conf/tomcat/catalina-server.xml and to the Connector running the port 9443 you can add an attribute proxyPort="443", the carbon console will be happy to run on 443.
For the services, my educated guess would be on the firewall / network rules, however without other information I cannot answer (or - they are working, just you may not try to access them by simple browser request)
I have a system named Windchill which runs in a CentOS 5.7 virtualbox;
The system consists of apache, oracle 11g, listener, windchillDS(openLDAP) and the application core (method server) which is a java process. All installed in the same vm(monolithic)
My question is related with the network, The system runs smooth on the network, but once I remove the network cable it stops working and the method server keeps restarting with the socket timeout error.
Im not a IT specialist, I manage the internal configuration of the system and I dont have an specialist to help me right now but I need desperately to make it run non networked in a laptop to show it for a customer.
I just want a hint of where may be the problem:
Does oracle runs non networked? Which configurations do I need to make it run without a network?
Maybe the problem is the listener?
I guess the problem is the oracle because of the socket timeout error with the database but Im not sure...
Sorry this is long and probably needs more explanation, please ask whathever you want!
I found this tip in another forum specific for the windchill product(login needed)
http://portal.ptcuser.org/p/fo/st/thread=52005&posted=1
It is related with Linux configuration to resolve the IPs:
"Edit your /etc/resolv.conf to look like this when not connected to a network:
domain local domain
search localdomain
nameserver 127.0.0.1"
Worked perfectly!
Thank you for your prompt answers guys!!!
Situation
I have a windows service which I would like to make highly available.
I have two unclustered servers (Windows server 2003 standard edition).
The question is:
What options do I have to make my service highly available in an automated way?
I can think of the asymmetric master-slave option which consists of keeping the service running on both machines with a communication heartbeat between them so one acts as the master and the slave takes over automatically whenever the master does not respond.
Do you know any other ways to implement this?
note: Please don't point me to this answer, I do NOT/won't/can't have clusters.
If you're windows service is hosting a web/wcf service, you can configure your client to have a primary service url and a secondary service url. Then you can modify the client connection logic to use the secondary service when connection to the primary service fails.
You can do this transparently by adding a router service which will do the logic above. Basically proxying the operations for whichever service it is connected to. But this adds another point of failure, the router service.
The simplest i cant think of is to make sure to set the service recovery options on your windows service/s. Something like this http://code.google.com/p/daemoniq/wiki/WindowsServiceRecoveryOptions

I suggest checking MS Patterns and Practices web site, there you could find advice on this topic (for example http://msdn.microsoft.com/en-us/library/ms998414.aspx)
