APEX Listener Confusion

I just downloaded and installed version 1.10.xx of the APEX Listener. After solving some problems - most of them due to "no need reading the manual", I've got it up and running. Now I can access APEX choosing from a variety of ports: APEX Listener, EPG, Apache's mod_plsql.

A few things are confusing me though:

1. At last weeks ODTUG was announced that the APEX Listener made it into production (the version number also indicates that status). But if you're looking at the official download site, it says: "The Application Express Listener is currently an early adopters release and is not supported by Oracle Support.".  So what is the - current - truth?

2. Reading the documentation (after all), I noticed: "The Oracle Application Express Listener supports the following Java Enterprise Edition application servers: Oracle WebLogic Server 11g Release 1 (10.3.3), Sun GlassFish Enterprise Server 3 +, Oracle Containers for J2EE 10.1.3.4 or higher". The funny thing is that if you download and install the OTN Database Development Appliance (which is great btw), Tomcat is used as webserver. In the early (or earlier?) adopter release, also Tomcat was mentioned as an option (and Glassfish wasn't).

3. For a reason I haven't figured out yet, I can't get to the listenerAdmin page (http://localhost:8888/apex/listenerAdmin). Username and password defined in the tomcat-users.xml are accepted, but I don't get the nice admin page I expected (the same when running the /Config at first). If you have a solution, please add it to the comments!

The good thing is that the APEX Listener (on Tomcat) starts up as a breeze now and the APEX pages perform nicely!

Push changed rows to an Interactive Grid

For pushing changes from the database to the end user, the regular solution is using websockets. A change in a record is detected - using a trigger or using the CQN (Change Query Notification) feature - and a notification is send to a websocket server. That websocket server broadcasts the notification over a channel to all browsers that are tuned in to that websocket channel. Then the browser reacts to that notification, usually showing an alert or refreshing a report. This trick is described on multiple sites, just Google for "oracle apex websockets" or similar.

So back in the old days, we used that notification in the browser to refresh the (interactive) report. But along comes the Interactive Grid (IG). While he full-refresh mechanism still works for IG, an IG has also the option to refresh just one row.  So wouldn't it be awesome that just the changed row(s) get refreshed upon a change in the database, instead of the whole report? Can we do it ... yes we can!

Refresh selected row(s) in an Interactive Grid

In my previous post I blogged about pushing changed rows from the dabatase into an Interactive Grid. The use case I'll cover right here is probably more common - and therefore more useful!

Until we had the IG, we showed the data in a report (Interactive or Classic). Changes to the data where made by popping up a form page, making changes, saving and refreshing the report upon closing the dialog. Or by clicking an icon / button / link in your report that makes some changes to the data (like changing a status) and ... refresh the report.  That all works fine, but the downsides are: The whole dataset is returned from the server to the client - again and again. And if your pagination size is large, that does lead to more and more network traffic, more interpretation by the browser and more waiting time for the end user.The "current record" might be out of focus after the refresh, especially by larger pagination sizes, as the first rows will be shown. Or (even worse) while you…

Dockerize your APEX development environment

Nowadays Docker is everywhere. It is one of the main components of Continuous Integration / Continuous Development environments. That alone indicates Docker has to be seen more as a Software Delivery Platform than as a replacement of a virtual machine.

However ...

If you are running an Oracle database using Docker on your local machine to develop some APEX application, you will probably not move that container is a whole to test and production environments. Because in that case you would not only deliver a new APEX application to the production environment - which is a good thing - but also overwrite the data in production with the data from your development environment. And that won't make your users very excited.
So in this set up you will be using Docker as a replacement of a Virtual Machine and not as a Delivery Platform.
And that's exactly the way Martin is using it as he described in this recent blog post. It is an ideal way to get up and running with an Oracle database …
