Upgrading Oracle APEX has never been easier

On May 12th Oracle APEX 21.1 was released. 

This post is not about why Oracle APEX 21.1 is worth an upgrade. You can see for yourself if you like the improvements in the Release Notes. Some companies upgrade once a year, some wait for the patch set bundle, and some upgrade very fast.

We upgraded our production instance this weekend. I blogged about how we do the upgrades and try to minimize downtime in the past. But upgrades have become even easier!

While the Oracle APEX kept running; 15 minutes install which of 5 minutes downtime, and we were done!

Note: it's always good to read the installation guide

Below what we did: 

  1. Download Oracle APEX
  2. Unzip
  3. Go into the directory 
  4. Connect to the Oracle Database with SQLcl or SQLPlus 
  5. Run 1 command:
@apexins.sql SYSAUX SYSAUX TEMP /i/

That was it! ... the installation did everything for us... and again this was in a live environment!
ORDS knows now that an APEX install is busy and suspends traffic for a certain time and next it comes up again:

Phase 1: no downtime


Phase 2 and 3: small downtime during phase 3 switch:


And done:


During Phase 3 downtime, I copied the new images folder.

I believe it wasn't really necessary as everything was working, but I did run the ORDS validate after the APEX install just to check it (while ORDS was still running):


And the proof of the max 5 minutes downtime:


I'm really impressed by the install and upgrade, it's basically an autonomous process these days 😀

using sysaux for apex is actually bad practice.

Dimitri Gielis said...

There are many discussions about the usage of SYSAUX or not.
e.g. https://community.oracle.com/tech/developers/discussion/4184427/usage-of-sysaux-tablespace-for-apex

I believe you need to decide for yourself if in your case it makes sense to have a dedicated APEX tablespace or not.

Hi Dimitri,

We run Apex version 5.0.4.00.12 with EPG. Should I install ORDS 21.1.1 first and then do the Apex 21.1 upgrade?

Thanks,
Leo

Hi Leo,

It doesn't really matter which you do first.
Typically I would install APEX first, then ORDS.

Hi Dimitri,

I really enjoyed the new Apex 21.1 features. Is the release date for the oracle cloud environment available anywhere?

Thanks,
Robert

You can directly install the new version, no need to uninstall.

Hi Dimitri,

thanks for this Blog. After Upgarding my apex from Version 19.1 to Version 21.1 as described here in your Blog.
I reveived the following message after accessing ORDS via Chrome.

"There is a problem with your environment because the Application Express files are not up-to-date! The files for version 19.1.0.00.15 have been loaded, but 21.1.0 is expected. Please verify that you have copied the images directory to your application server as instructed in the Installation Guide."

do you have any tipp what could be wrong? regards Udo

Hi Udo,

It looks like the images folder is not up-to-date.
Did you copy the images folder? or did you update the CDN?
If you did, try to refresh your page or empty the cache of the browser.

Hope that helps,
Dimitri

Hi Dimitri, do you happen to know in version 21.2 the account menu acts differently? In 21.1 I can click the top right to log out. In version 21.2 if I click it nothing happens?

It also looks like Manage Requests / Manage Instance / Manage Workspaces / Monitor Activity is no longer across the top bar (you just use the icons?)

Or I'm wondering if I messed something up

Dimitri Gielis said...

it's still there in APEX 21.2... it's the icon with the person and wrangler, next to the help icon.

Michael said...

I changed over to use the CDN and it all came back. When I flipped to local images it stops working, so something wrong with my images. Is it recommended to use the CDN anyways?

Dimitri Gielis said...

In most cases CDN makes a lot of sense yes.

Hello Sir, Can you please share steps to upgrade apex from 19.1 to 21.2. As starts from 20.1 ORDS is required and customer will install ORDS.So first we need to install Apex right and then ask our customer to install ords as while installing customer need ORDS user which we create using @apex_rest_config.sql script or with 21.2 version that will be created automatically.

Hola dimitri:

Tengo este problema con APEX:
There is a problem with your environment because the Application Express files are not up-to-date! The files for version 19.2.0.00.18 have been loaded, but 21.2.0 is expected. Please verify that you have copied the images directory to your application server as instructed in the Installation Guide.
