JDK for R12.2

[big]

Hi,

On R12.2.4 on AIX

How to know if an Oracle JDK is installed and used by R12.2  and if yes how to know it's version?

Or a natif IBM JDK is used by E-Business R12.2 ?

Thanks

Check the following MOS note.. There you will find java related sections.

        Java Versions
  ... Java Versions - Via Operating System
  ... Java Versions - Via SQL
  ... Java Versions - Via Application

Thank you.
Is JDK version the same as java version?

Following 858957.1 , I ran:

SQL> set serveroutput on
SQL>  exec fnd_aolj_util.getclassversionfromdb('oracle.apps.inv.transaction.server.BaseTransaction');
>>> Class: oracle.apps.inv.transaction.server.BaseTransaction
$Header: BaseTransaction.java 120.86.12020000.7 2014/02/21 08:43:00 pdong ship $
>>> Class: oracle.apps.inv.transaction.server.BaseTransaction
$Header: BaseTransaction.java 120.86.12020000.7 2014/02/21 08:43:00 pdong ship $

PL/SQL procedure successfully completed.

JCL - 20130616_01 based on Oracle 7u25-b12

Then whatis my JDK? Does R12.2 use its own JDK or OS native JDK?
Regards.

There are different components in EBS and they use different java executables and libraries that are deployed with JDK or JREs.

Note thet; Oracle E-Business Suite application tier uses the JDK from a fixed installation location, [IAS_ORACLE_HOME]/appsutil/jdk

**Please see -> Overview of Using Java with Oracle E-Business Suite Release 12.x (Doc ID 418664.1)

See the following also (to understand the JDK usage in EBS) ->
