Installing APEX 2.2 on XE

As you might have noticed APEX 2.2 is available for download. On the download site nowhere is stated that is doesn’t work for on XE, but installing on XE fails directly. How to solve this?

This is due to the following lines in the upgrade procedure in the file apexins.sql:
declare
t_edition varchar2(30);
edition_is_xe exception;
begin
--select edition into t_edition from v$instance;
execute immediate 'select edition from v$instance' into t_edition;
if nvl(t_edition,'x') = 'XE'
then

dbms_output.put_line('---------------------------------');
dbms_output.put_line('- Ap Ex cant be installed in Express Edition.-');
dbms_output.put_line('-------------------------------------');
raise edition_is_xe;
end if;
exception
when edition_is_xe then raise;
when others then null; -- no edition column, not xe
end;
/
Once the lines are REM’med out the upgrade process runs fine. After finishing the other steps from the upgrade manual I can login, change and run previously defined applications. The main difference with the “lightweight” APEX installed with XE is that there are workspaces defined for every Apex-developer (with the same name).

At this point you are only missing access to the workspace INTERNAL using the ADMIN account. This is easily solved by creating a new admin account by logging in in SQLPLUS as FLOWS_020200 user (unlock the account first) and issue:
begin
wwv_flow_api.set_security_group_id(p_security_group_id=>10);
wwv_flow_fnd_user_api.create_fnd_user(
p_user_name => 'admin2',
p_email_address => 'myemail@mydomain.com',
p_web_password => 'admin2') ;
end;
/
commit;
Now we can administer APEX on XE with ADMIN2 as were it a “normal” APEX installation!

Hello Roel !
I cannot find out where to copy the "images"-directory from the installation-zip into the XE-tree as told in the post installation tasks. I used /i/ as @apexins-parameter as recommended but now I am standing in the dark. The diretories named in the installation docu does not exist in the XE-version. Do you have a hint ? Thanks !

Andree,

/i/ is a virtual directory. When using XE (on Windows XP) you can create a new Network Location using the Wizard (create networking location). There you can enter http://127.0.0.1:8080/i/ as the location (use system/systempassword when prompting for user/password). Now you have a virtual directory (let's call it 'Z')in your Explorer, and you can copy the images to z:\img\.

Hello,
Just googling APEX and XE and this blog came up near top. Do you know of any issues installing APEX 2.2 (not an Upgrade) with Oracle XE?

Any other websites purely that talk about supportability and other issues with Oracle XE and APEX?

Am aware of OTN but wondering if there were any site specific to this setup?

Regards,
ApexDev

ApexDev,
Before installing APEX on XE you first need to de-install XE (because Apex comes pre-installed on XE). I've never done this (there was no need), so I can't help you out there. Other sites of interest about Apex (on XE or other flavour):

Ofcourse this is absolutely not complete list, but something to start with...

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…

apex_application.g_f0x array processing in Oracle 12

If you created your own "updatable reports" or your custom version of tabular forms in Oracle Application Express, you'll end up with a query that looks similar to this one:
then you disable the "Escape special characters" property and the result is an updatable multirecord form.
That was easy, right? But now we need to process the changes in the Ename column when the form is submitted, but only if the checkbox is checked. All the columns are submitted as separated arrays, named apex_application.g_f0x - where the "x" is the value of the "p_idx" parameter you specified in the apex_item calls. So we have apex_application.g_f01, g_f02 and g_f03. But then you discover APEX has the oddity that the "checkbox" array only contains values for the checked rows. Thus if you just check "Jones", the length of g_f02 is 1 and it contains only the empno of Jones - while the other two arrays will contain all (14) rows. So for processing y…

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 …
