In this 3 step short tutorial, Charitha describes how you can configure your WSO2 WSAS instances to facilitate more than one instance within a single host.

Step 1

Download the latest version of WSO2 WSAS from here

Extract the downloaded zip in to a directory in your file system. We can name this location as CARBON_HOME

Step 2

Go to CARBON_HOME/conf directory and the open transports.xml file. Update the http and https ports as follows:

<parameter name="port">9764</parameter>

<parameter name="port">9444</parameter>

Save and close the file.

Step 3

Similarly, change the ports of the other WSO2 WSAS instances. You can follow the same steps to change the default ports in WSO2 Governance Registry, WSO2 Identity Server and WSO2 Mashup Server products.

Step 4

In the case of the WSO2 ESB, in addition to the above change, you should change the non-blocking HttpCore + NIO transports in CARBON_HOME/conf/axis2.xml

<transportReceiver name="http" class="org.apache.synapse.transport.nhttp.HttpCoreNIOListener">
<parameter name="port" locked="false">8281</parameter>

<transportReceiver name="https" class="org.apache.synapse.transport.nhttp.HttpCoreNIOSSLListener">
<parameter name="port" locked="false">8244</parameter>

Applies To:- WSO2 WSAS-3.0 or later, WSO2 ESB-2.0 or later, WSO2 Governance Registry-2.0 or later, WSO2-IS-1.5 or later

I tried the steps above, but when I do this I get login issues. It appears as though when I log into one (server1), and then login to another (server2) the second login force a logout on the first server (server1).

It would seem the only thing that they are sharing is the Keystore values: CN=wso2carbon, OU=None, L=Seattle, ST=Washington, O=WSO2, C=LK for instance. Is this causing my problem?

Thanks for any light you can shed on the issue.

Cheers!

I think the reason for this is that you may be using the same browser instance. For example if you are using IE to access one server, try using firefox or anyother browser to access the other browser. See it is works. You can also use different firefox profiles also.

Thanks Samindaw!

I didn't even think about the client side....

Thanks Again!

Enterprises are inherently complex, comprising of hundreds of applications with completely different semantics. Some of these applications are custom built, where as some are acquired from third parties and some even can be a combination of both and they can be operating in different system environments.
