    Install Apex (Application Express) Formerly HTMLDB
    Friday, November 10, 2006
    Register for R12 upgrade
    Some time ago I read a post about HTMLDB at Vidya Bala's Blog She has mentioned nice description about HTMLDB & Installing HTMLDB 2.0. You can check her post at Install HTMLDB 2.0

    Now HTMLDB is called as Application Express or more commonly as Apex. Latest Apex Version is 2.2 and today I'll quickly cover Installation of Apex Version 2.2. You can find Installation Document and software at end of this post.

    Requirement:
    In order to install Apex (Former HTMLDB) ver 2.2 you should have
    --Application Server Version 1.0.2.2 or higher
    --Database should be version 9.2.0.3 or higher
    --Disk Space around 500 MB on middle tier (Application Server)
    --Tablespace (in which you will install Apex ) with around 100MB free space
    --System tablespace with around 85 MB free space
    --Database shared pool size should be 100MB or more

    Tablespaces:
    At time of Apex installation it asks for tablespace for user data & tablespace for Apex files. You can use existing single tablespace for both or can create these two tablespace. For better understanding I will create two tablespace one for User data & other for Apex files.

    Assumptions
    Below Apex 2.2 Installation steps are of Database version 10.2.X and application server version 10.1.2.0.2 (There might be minor changes on other database or application server version)

    Pre Installation Configuration
    Login to database and create two tablespace

    create tablespace tsapexf datafile '/$datafile_location/tsapexf01.dbf' size 50M autoextend on next 10M maxsize 300M;

    create tablespace tsapexu datafile '/$datafile_location/tsapexu01.dbf' size 50M autoextend on next 10M maxsize 300M;
    These tablespaces we are going to use during Apex Installation

    Loading Apex into Database

    Login to middle tier(Application Server) & download Apex 2.2 software from location mentioned at end of this post (software is with name apex_2.2.zip);
    Copy it to location where you want to install Apex on Middle tier ; assume its /u01/dev
    unzip software as ; unzip apex_2.2.zip
    This will craete a subdirectory with name apex ; cd apex
    sqlplus system@tns_alias as sysdba (From middle tier connect to database as sysdba)
    @apexins.sql {passwd} {ts for user} {ts for files} {ts for temp} /i/ {connect_info}

    Where
    passwd - Password for Apex Super User
    ts for user - Tablespace for User data (Created above)
    ts for files - Tablespace for Apex files (Created above)
    ts for temp - temporary tablespace (Usually Temp)
    i - is the alias for image directory configuration in Application Server (Apache httpd.conf)
    connect info - TNS Alias to connect to database from middle Tier

    @apexins.sql mypasswd tsapexu tsapexf temp /i/ tns_alias

    This step will take 1-2 hours depending on server configuration


    Configure Apex at Middle Tier
    (Application Server)
    Create a file marvel.conf in $ORACLE_HOME/Apache/modplsql/conf

    Replace ORACLE_HOME, hostname, port number, service_name, and apex_public_user_password with values appropriate for your environment.

    #########

    Alias /i/ "/u01/dev/apex/images/"

    AddType text/xml xbl
    AddType text/x-component htc


    Order deny,allow
    PlsqlDocumentPath docs
    AllowOverride None
    PlsqlDocumentProcedure wwv_flow_file_manager.process_download
    PlsqlDatabaseConnectString hostname.domainname:db_port:SID ServiceNameFormat
    PlsqlNLSLanguage AMERICAN_AMERICA.AL32UTF8
    PlsqlAuthenticationMode Basic
    SetHandler pls_handler
    PlsqlDocumentTablename wwv_flow_file_objects$
    PlsqlDatabaseUsername APEX_PUBLIC_USER
    PlsqlDefaultPage apex
    PlsqlDatabasePassword password
    Allow from all

    #######

    include marvel.conf in httpd.conf like below so that it can be invoked each time Apache(Web Server) Starts

    include "/replace_this_with_oracle_home/Apache/modplsql/conf/marvel.conf"

    Update this configuration change in DCM repository (This step is required only on 10g Application Server, Skip this if you are configuring it with Apps 11i or standalone HTTP Server)

    Make sure Alias /i/ "/u01/dev/apex/images/" this alias in marvel.conf is pointing to right apex images directory


    Post Installation Steps
    dcmctl updateconfig -ct ohs
    opmnctl restartproc ias-component=HTTP_Server (Restart HTTP Server to check it)

    Now try access application via URL
    http://hostname.domainname:port/pls/apex

      Nice post on Apex, Atul....you should add that they may need to change the image directory within the marvel.conf file, just in case they decided to install Apex within another directory, as I did.

      Is it critical that application server 10g is installed before apex?

       
    • At 10:28 PM, Blogger Atul Kumar said…

      No, You just need a HTTP Server and an Oracle Database (10g AS is just one option)

      Hi Atul,
      While installing apex ,
      i get an error
      oracle disconnected ,
      memory exhausted ,
      Thanks,
      Amol

       
    • At 7:37 PM, Blogger Atul Kumar said…

      Amol,
      Check if you have enough memory in database. Check alert log for any messages furher. Make sure you got enough memory in database shared pool size should be 100MB or more

      as mentioned in preinstall steps

       
    • At 3:07 PM, Blogger amol said…

      Thanks Atul ,
      Looks like it was sqlplus issue ,
      i was running the script from a remote machine .
      i ran the script from the same machine and it worked fine .

      hi , after configuring dads.conf , i am getting

      503-Service Temporarily Unavailable
      The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

      any clue , pankajch1982@gmail.com

       
    • At 7:30 PM, Blogger Atul Kumar said…

      Check error_log in $ORACLE_HOME/Apache/Apache/logs if this is 10g AS or

      $OS/ohs/Apache/logs/error_logs if this is standalone apache


      for error related to 503

       
    • At 1:45 PM, Blogger qAnand said…

      Hi Atul,
      This section looks interesting. Do we need to install this separately in ebusiness suite environment or installation of ebuss suite installs htmldb also?
      Does it involve separate license cost?

      Please update about this also.

      Thanks
      Anand

       
    • At 1:51 PM, Blogger Atul Kumar said…

      E-Business Suite doesn't install Apex you have to install is seperately. For Licensing check Oracle Sales

       
    • At 2:01 PM, Blogger qAnand said…

      Thanks Atul.
      I checked in other sites and its mentioned as license free, anyway as you suggested will check with Oracle Sales.

       
    • At 8:55 AM, Blogger qAnand said…

      Hi Atul,
      After struggling, I got the Oracle Apex installed and created a demo application (which displays report). Now the challenge is to integrate this demo-application with my EBusiness suite.
      Is it possible? Can you throw some light in this area?

      Regards,
      Anand

       
    • At 9:07 AM, Blogger Atul Kumar said…

      Anand,
      What do you mean by integration of Apex with E-Business Suite here.

      How you wish or what you want to do from E-business suite ?

       
    • At 9:23 AM, Blogger qAnand said…

      Thanks for the reply. In simple words - Create a new responsibility with some menus/submenus. On click of the links/submenus, the application-report (developed using apex) should open without again prompting for any username/password.

      Is it possible to achieve?

      Regards,
      Anand

       
    • At 9:59 AM, Blogger Atul Kumar said…

      Anand,
      So you want authentication to be enabled via FND_USERS. In Apaex you have various authentication scheme or you can create your own authentication scheme and map users in apex with users in FND_User but this is all customization.

      For standard configure SSO with Apaex and SSO with E-Business Suite and then these two applications (apex and e-business) are partner application against same SSO and user can login without re-authentication but this is again big thing.

       
    • At 10:24 AM, Blogger qAnand said…

      Thanks Atul,
      You said it is possible now I'll give a try.
      This site is AskTom for APPS.

      Keep up the great work. Awaiting your posts on Apex-SSO

      Sorry to bother you Atul. I am stuck again with ApEx. Can I email you in detail?

      Hi Atul,

      I am new to the DBA world and many of my freinds who are into this feild have recommended your site, an amazing fact was that one of them is not a DBA but still he knew about you and said that there is a lot of Quality stuff here.

      As a matter of fact i am trying to install an HTML database , after following all the steps that are given on your site as well as the Companion Cd installation guide, the installation is not working , the http server when invoked says Internal server error , i have checked the dads.conf file , what i am trying to do is that i have a 10g database on which i have installed the htmldb by providing all the connect identifier but still its not working . Can you provide some help on this issue.


      Regards,
      Ashish

       
    • At 6:31 PM, Blogger Atul Kumar said…

      Ashish,
      Thanks for compliment, If you have followed doc properly then in order to find issue of Internal server error go to Web Server (HTTP Server) under which you have configured dads.conf like $ORACLE_HOME/Apache/Apache/logs and look for error_log and check what error message it is reporting and look for possible cause of problem reported in error_log

       
    • At 10:33 AM, Blogger Ashish said…

      Hi Atul,

      Thanks for the solution, i had a look at the error logs they said its a configuration prob, i have modified the dads.conf file and now the login page is diaplayed correctly but the fact is that the images are not being displayed properly and when i am trying to login to the page its showing an error. Please suggest.

      Ashish

       
    • At 7:14 PM, Blogger Atul Kumar said…

      Ashish Good that you moved to next step.

      For image check if image directory is mapped correctly in dads.conf to images directory on file system.

      For login problem what error message you are getting in logs

       
    • At 10:37 PM, Anonymous Chetan Parmar said…

      Hi,

      I've been reading your post but don't see a solution to "Error 503 Service Temporarily Unavailable..."

      I checked the Apache logs and all I see is this:
      "10.64.0.24 - - [18/Sep/2007:17:29:51 -0400] "GET /pls/apex HTTP/1.1" 302 5
      10.64.0.24 - APEX_PUBLIC_USER [18/Sep/2007:17:29:52 -0400] "GET /pls/apex/apex HTTP/1.1" 503 441

      Why am I getting the above error? Thank you for you help and nice post!

       
    • At 10:43 PM, Blogger Atul Kumar said…

      Chetan,
      share your dads.conf information the one under /pls/apex

      check if database user APEX_PUBLIC_USER can connect to database using connect string defined in {location /pls/apex} with directive

      PlsqlDatabaseConnectString

      Check if password is correct and user is not enddated/ locked

       
    • At 3:19 AM, Anonymous Chetan Parmar said…

      Atul thanks for the quick reply. I resolved the issue but only after you jogged my memory. The APEX user was locked but off course I was over thinking the issue and forgot to check the basics! Also, I believe the 'anonymous' account needs to be unlocked but maybe you can verify that for the group. Thank you for quick reply! Chetan.

       
    • At 5:38 AM, Blogger Ashish said…

      Hi Atul,

      My images problem was solved by changing the path in the dads.conf file..........thanks for all your help.......now I am facing a strange problem , when I am trying to invoke the enterprise manager it says that the database status is corrently unavailable. I tried to bounce the enterprise manager but still the problem persists.Please Help.

      Thanks
      Ashish

      I am new to apex.As per your Installable steps.I have installed
      apex into database sucessfully but i am getting stuck while configuring it with middle tier(application server).
      In your Article you are creating marvel.conf in "D:\apache\apache\conf"
      and then include this file into httpd.conf.

      What will be the contents of marvel.conf.

      Could you please guide me.

      Hi
      I have a problem in apex
      Please follow the steps
      For example:
      Application 162/page33/under regions click report/column attributes tab/(click edit link image)mgr/message on top of the page  Report attributes updated.
      & If interactive report  Action Processed.

      Now why without change and press apply change page updates?!
