DB-APEX version mismatch

[lukash33]

Please be carefull:
https://docs.oracle.com/database/apex-5.1/HTMIG/Oracle-AE-installation-requirements.htm#HTMIG377

"Oracle Application Express release 5.1 requires an Oracle Database release 11.2.0.4 or later, including Enterprise Edition and Express Edition (Oracle Database XE)."

Therefore one should not try to go to APEX 5.1 with 11.2.0.2 XE because there is no 11.2.0.4 XE anywhere.

So, document requires 11.2.0.4 which does not exist for XE. Though personally I note no issues using APEX 5.1 with 11.2.0.2 XE in your image

I think you got that wrong. XE is explicitly mentioned here, because there is no 11.2.0.4 of XE.

This means you CAN install APEX 5.1 on XE 11g

May I am wrong. May ORACLE is not correct. Pls see also their Doc ID 1344948.1:

"Minimum Database versions for APEX:

• Beginning with Application Express 5.0, the minimum database version is 11.1.0.7.
• Beginning with Application Express 5.1, the minimum database version is 11.2.0.4."

Alright, so please read this from the APEX 5.1 Installation Guide:

Oracle Application Express release 5.1 requires an Oracle Database release 11.2.0.4 or later, including Enterprise Edition and Express Edition (Oracle Database XE).

This includes XE. Also I heard the APEX Dev Team explicitly stating that XE runs APEX 5.1.

So no need to worry, they don't forget about the free version :-)

In fact Oracle XE is 11.2.0.2, not 11.2.0.4. So why I bother:

SQL> select * from v$version where banner like 'Oracle%';
BANNER

Oracle Database 11g Express Edition Release 11.2.0.2.0 - 64bit Production

But I can admit it does not matter much.
