Multiple listeners in Weblogic

Question

Hi:
Can I deploy multiple Apex listeners pointing to different Databases in the same Weblogic server? Is there any documentation or OTN Notes on this?
Regards

You don't need multiple domains to run multiiple listeners. This is exactly what we are doing in or development environment.
As mentioned by Udo, you need to have a different config dir configuration for each apex.war deployment in WebLogic.
For example, you may have two development databases. DEV1 and DEV2
copy the apex.war file twice and rename to apex_dev1.war for the DEV1 instance and apex_dev2.war for the DEV2 instance.
Unzip/unjar the file and modify the web.xml file as follows in apex_dev1.war:
<context-param>
<param-name>config.dir</param-name>
<param-value>${apex_dev1.dir}</param-value>
</context-param>
Unzip/unjar the file and modify the web.xml file as follows in apex_dev2.war:
<context-param>
<param-name>config.dir</param-name>
<param-value>${apex_dev2.dir}</param-value>
</context-param>
In the WebLogic console go to the Server configuration->Server Start tab and under the Arguments section enter the following (or wherever depending on your environment):
-Dapex_dev1.dir=/ora/Middleware/user_projects/applications/apex_dev1_config;-Dapex_dev2.dir=/ora/Middleware/user_projects/applications/apex_dev2_config
You must create bothdirectories first before starting the server.
Deploy the new war files via the console in Weblogic and then goto /apex_dev1/listenerConfigure and configure it for the appropriate database. Do the same for apex_dev2.
This way you will know which DB you hitting via the URL.
good luck.
