    Difference between Oracle Apps 11i and R12 (Technical)
    Sunday, April 08, 2007
    Register for R12 upgrade
    Based on high influx of mail from users requesting difference between Oracle Applications Release 12 and 11i , I decided to dedicate this post to outline few major technical difference.

    Database:
    Database Version in 11i (11.5.9 & 11.5.10) was 9i Rel 2 where as in Release 12 its 10g R2 (10.2.0.2)

    Application Tier:
    Tech Stack in Application Tier consist of iAS(1.0.2.2.2) & Developer 6i (Forms & Reports 8.0.6) but in Applications R12 it is build on Fusion Middleware (10g Web Server and 10g Forms & Reports)

    Sub component in Application Tier
    A) HTTP Server or Web Server in R12 is Version 10.1.3 which is built on Apache version 1.3.34. In apps 11i it is Version 1.0.2.2.2 built on Apache Version 1.3.19
    B) Jserv in apps 11i is replaced by OC4J (mod_jserv is replaced by mod_oc4j)
    C) Forms Version 6i in Apps 11i is replaced by Forms 10.1.2.0.2 in R12
    D) Reports Version 6i in Apps 11i is replaced by Reports 10.1.2.0.2 in R12
    E) JDBC version is changed from version 9 in apps 11i to version 10.2.0 in Apps R12
    F) modplsql or mod_pls is removed from Apps R12 (What will happen to my mod plsql applications- coming soon* )
    G) Java processes use JDK/JRE version 1.5.0 in R12 against JDK version 1.3.1 or 1.4.2 in Apps 11i
    H) For various environment variable changes check below picture


    I) New top INSTANCE_TOP added in Release 12 for configuration and log files

      Client Plugin will be Sun JRE(1.5) replacing the good old Jinitiator.

      Rahul,
      You can try either of two. They are two version of ERP from Oracle.

      Once you download R12 software (38GB software only) then when you install that software you get an option to install demo or fresh/prod (without demo) erp

      R12 uses DBI (Daily Business Intelligence) Though you can still integrate 10.1.2 discoverer with R12

      Hi,
      I am trying to install Oracle Apps12 on RHEL but at the end of installation only one error display which is

      "Login Page
      checking URL = http://apps.ib.com:8014/OA_HTML/AppsLogin
      RW-50016: Error: - {0} was not created:
      File = {1}"

      I am not sure if it requires any patch like 5885627.


      It would be great if any one can suggest the solution or provide the link from where I can get this patch As I don't have access to metalink.


      Thanks

      Hi Atul,

      Where is the report server executable in R12. In 11i, we can check the OS server process for reports and forms server with ps -ef|grep rwmts and ps -ef|grep f60srvm. But in R12 how do we check the OS process for forms and reports server?

    • At 9:50 PM, Anonymous Anonymous said…

      Regarding --HTTP Server or Web Server in R12 is Version 10.1.3 which is built on Apache version 1.3.34. In apps 11i it is Version 1.0.2.2.2 built on Apache Version 1.3.19

      It has inbuilt Apache/2.0.52 .

      Can anyone tell me from where can i downoad oracle apps 11i since it is not there in the edelivery.oracle.com

       
    • At 8:18 AM, Blogger ERP said…

      Dear All,

      In R12 Reports Server is not used, and no servlet or cgi is used
      instead reports executable rwrun is used directly.

      After you submit any request via concurrent then immediately you can grep for executable rwrun on the unix server.

      Oracle Reports, like Forms, is supplied from the Oracle Applications 10.1.2 home,available via Concurrent Manager
