    Are you looking for Apps DBA training ? ( Free Ofcourse )
    Are you a DBA and looking for Career or Job in Apps DBA ?
    Are a Oracle DBA and interested in Learning Oracle Apps or want to become Oracle Apps DBA ?

    then you are at right place

    Image taken from Application Architecture Document

    There is lot of Oracle Apps Training material available on net/Oracle Site at the same time lot of training Institutes are providing Oracle Apps DBA, Now its up to you if you want to learn E-Business Suite at your own or want a formal training as Apps DBA. Lets start with what all you should learn as an Oracle Apps DBA.

    First thing is you should be Good in Oracle Database Skills and I assume you are already very good as DBA or don’t need any formal training as DBA. To become Oracle Apps DBA first and important thing is that you should be very well familiar with Oracle Applications/E-Business Suite Architecture . Give as much time as possible Architecture & understand all basic component . Its few , Webserver (Oracle-Apache), Forms, Reports, Concurrent Manager, Discoverer and Database. (Discoverer you can skip & can read later but remaining are building blocks of Oracle Applications. Now where to find basic Architecture and related Architecture ?

    EBS Documentation

    this link contain E-Business Suite but its hell lot of guide & you will not be able to finish it until you die. So from here Open Guide “Oracle Applications Concept” & read chapter 1 only that too just page 1 to 19 ( Only 19 pages & your Basics is done ) I think its not much . If you understand any thing in that put a comment on this Blog & I ‘ll definately Explain or Can even mail you .

    So moving on to next part of your Oracle apps DBA training , you should know Installation. You can try installing oracle E-Business Suite on your test systems for that you can pick guide
    Oracle Applications Installation Guide: Using Rapid Install In documentation location mentioned above . This might sound tough for first time but believe me it pretty simple , Everything GUI ( You can ignore creating Staging for Dump but if you are a oracle DBA you can do it pretty well ) Now if you encounter any Issues in Installation you can create Metalink Tar or if you don’t have metalink Account you can post questions in Oracle E-Business Suite Forum .
    So this conclude Two important aspects of your Oracle Apps DBA Training , I am again focusing on Architecture of Oracle Apps is very critical in APPS DBA Training. If you like above material & still want to read remaining parts of Oracle Apps Training like, AD Utilities for Patching (Very Important for DBA), Cloning, Upgrade wait for my Next Blog I will Update this blog as soon as I create tomorrow or day after , till that time clear your Oracle Apps Concept . Believe me learning Oracle Apps is very simple if you Study carefully & with Interest.
    Plsssssss leave comment.

      I am really touched the way you put togather facts for Apps DBA. You are in UK but due to your auspicious work, you have reached everywhere.

      Hi Atul,
      It is really nice to have your email so quick. I book marked the link for future reference. As a DBA, I have setup 9i, 10g databases from scratch and applied patches,performed backups and installed 10g Apps server and configured report servers. I have gone through Oracle Financial 10.7sc intensive training in India, will it help me in becoming Apps DBA? I am a really good developer as well and got certification for developer 6i Release 2. Now, looking to my exposure, will you please tell me what step should I follow to start ii1 Apps DBA? Do you think that classroom training is required for Apps DBA?
      Thanks,
      Dilesh

    73. Atul Kumar says:

      Dilesh,
      I think its more than enough. I would suggest you instead of class room teaching start with hands on Installation, patching & cloning 11i.

      Good luck for your Journey towards Apps DBA

      Atul,
      Thanks for your assurance. I wanted to know one more thing. Is it possible to configure HTTPS only for the login screen, so that the username and password can be pass through internet encrypted instead of clear text? My organization does not want to do any investment in procuring any certificates. Is it possible to accomplish this without making any investment?

      Waiting for your update….

    85. Atul Kumar says:

      Yes you can tweak around using sso. For free you cabn use test certificates comes free with oracle HTTP Certificates

    86. qAnand says:

      Thanks for the update Atul. But can you please elaborate? Probably a URL or a link in your site would help. We are not using SSO here.

      Thanks

      Anand ,
      To be frank it is bit complicated (not very straight forward) I did some work on 10g AS Integration with Apps for SSO but I don’t to post it on site at this minutes . Here is metalink note which you can refer metalink note

      233436.1 Installing Oracle Application Server 10g with Oracle E-Business Suite Release…

      & then configure SSL for HTTP Server on SSO (Infra tier).

      You have to study a lot for this

      Hi Atul,
      The Documentation will really help a beginner like me. I am a beginner in apps dba and I need to know if Oracle applications can be installed on a home PC ? I mean in one PC with a configuration of 512 MB with 40GB hard drive or do I need to look for a sever in Web, something like webhosting ? If so, which is my best option ?

      Regards,

      Rajesh

    113. Atul Kumar says:

      You don’t need server and can be installed on normal computer but you might need more CPU and harddisk.

      Check installation guide with prereq. for installing apps

      Hi Atul,

      First of all a very big thanks for the wonderful help that you have been providing for all learners like us.I would like to know if there is any site where we can get more knowledge on core DBA as well.
      If so that would also be a great help again …
      thanks & regards

    115. Atul Kumar says:

      Hi SEha,
      Thanks for these nice words. For core DBA I am not aware of any site which provide free training but my recommendation . Go to oracle documentation and pick oracle dba documentation nd go through them

      Dear Atul,

      is it possible that the client ( desktop tier) connect to forms server without the web server ( apache) and in case the apache server is down what will happen?

      No , Initial connection will always be via Apache in standard Oracle Applications 11i

    119. nagesh says:

      Hi Atul,

      I have basic knowledge of oracle 9i database, i am looking my career as ORACLE APPS DBA. Will it possible for me to achieve that.

      I had been with the Oracle application concepts, im not finding any difficulty in understanding them.

      It really sounds good.

      Note: I dont have depth knowledge on database. I am working as UNIX Administrator.

      regsrds,

    120. Atul Kumar says:

      Yes Nagesh, you can be good apps dba provided you focus on basics and work hard

      Thanks Suhaag, Step by Step will take quite a lot time for each post but I’ll try to put as much detail as I can in my future posts..

    123. Anonymous says:

      I have gone through the material you recommended (11iconcepts pg 1-19). It is quite interesting not very complicated and not long just as you had said.

      So basically, the aim was to grasp the architecture of the E-Business suite.

      Now am looking forward to the installation part of it.

    126. Anonymous says:

      hi Atul, Ur blog is good but i found ur blog is just overview on all the topics, why dont u go more deeply on all the contents.

    127. Atul Kumar says:

      Thanks for feedback, yes I agree majority of posts are on overview and reason for that is most of guys I met are not clear of concepts even so I thought of dicsussing them first though I have some posted on few things in detail as well . Do let me know on which topic you want me to cover in detail and I’ll try to cover them

    146. Raghu says:

      Hi Atul

      I have been following your site for past couple of months. Its very informative but one suggestion I have is that for people who don’t have access to metalink and oracle support, could you not create a FAQ of sorts where you can put in the frequent problems which have been encountered by you and the solutions for those problems.
      Your site is nice but there’s too much theory in it…Or maybe thats why you have those webinars/Online Training on the site….

      Hi…Atul
      I’m beginner for oracle APPS DBA.I’ve got knowledge in oracle DBA..so could plz advice me how to become a APPS DBA

    165. Atul Kumar says:

      Good Question (how to become apps dba)

      My tips

      1. Go through Oracle Apps Architecture Guide
      2. Go through Oracle apps Installation Guide
      3. Install Oracle Apps
      4. Go through file system (physically on server) and from Oracle Apps concepts guide
      5. Learn Start/Stop of apps
      6. Go through ad utilitites guide
      7. Apply apps patch using adpatch
      8. Check ad controller adctrl to see worker status
      9. Clone apps instance using metalink notes
      10. Finally try backup

      This should cover most of day to day task for apps dba’s

      For next level learn Advanced deployment like
      1. Mulitple Middle tier configuration
      2. Setting load balancer and DMZ
      3. Integrating apps with OID/SSO
      4. Upgrade from 11i to R12
      5. Confihuring SSL
      6. Upgrading tech stack in apps
      7. Upgrading database with apps
      8. Configuring RAC with apps database

      For documentation check http://www.oracle.com/technology/documentation/applications.html

    166. Hitesh Tomar says:

      Hi Atul,

      Undoubtedly you are really doing good job.

      Would you help me out with some information on Oracle Apps 11i Functional as i am planning to do this course and also about the future prospect and scope for this course.

    167. Ash says:

      hi Atul,

      I want a conceptual concept of Oracle Apps like
      — what exactly the six different servers contains.
      — is it same as our database server.
      — what is the archietecture of these six servers.
      — where the actual html forms/ frx files/ report files are stored etc…

      I am new to the Apps.

      Please reply

      Thanks,
      Ash

    168. Atul Kumar says:

      – what exactly the six different servers contains.
      Database Server, Web Server, Forms Server, Concurrent Manager Server, Admin Server, Discoverer Server (This is for 11i)

      – is it same as our database server.
      Database Server for apps is same as standard database server with some additional things like Autoconfig under apputil directory in Oracle Home. Forms & web server are based on Oracle Application Server

      – what is the archietecture of these six servers.
      Check Oracle Apps Architecture Guide

      – where the actual html forms/ frx files/ report files are stored etc…
      On application tier under APPL_TOP under their own product directories (check file system under Architetcure Guide)

      http://onlineappsdba.com/index.php/2006/08/08/apps-architecture/

    169. Ash says:

      thank you atul for your reply

      is there specific reason for dropping discoverer server in 12i architecture

      Thanks
      Ash

    170. Ash says:

      Hi Atul,

      for basics i read Ch 1 & 2 of Oracle Application Concept.
      I installed R12 on my test machine.

      but still, not getting clear idea.
      for more basic knowledge which chapters should i read either from concepts or from installation guide.

      please suggest.

      Thanks

      what is the meaning for vision demo database

    184. Atul Kumar says:

      @ Khaja,
      Vision Demo Database means Oracle Apps will be installed with demo data which functional guys can use to test functional setup. From DBA’s point of view size of database will be much bigger when selecting Vision compared to fresh database.

    185. khaja says:

      hai atul you told me answer for “how to restrict users from loging in to instance even front end is up and running?”

      answer is this,

      Configure Firewall between users and application tier and block web server port on firewall
      please tell me how can we do this?
      thanku

    186. Atul Kumar says:

      @ khaja,
      Fir decide which Firewall you are going to use (hardare or software) then use appropriate firewall document to block/allow port.

      If your application tier is on Linux you can use pre installed software firewall “iptables”

    187. Vishnu says:

      Hi Atul,

      Is the book Oracle Applications DBA Covers 11i and R12 sufficient enough to prepare for the exams 1z0-235,1z0-236 and 1z0-233 atleast to an extent of 75% to become an Oracle Apps DBA 11i ?
      Please guide me in this.

      Thanks in advance.

    188. Vishnu says:

      Sorry, I have not mentioned the author of the book

      book – Oracle Applications DBA Covers 11i and R12
      author – Joyjeet Banerjee
      Publications – Tata McGraw-Hill Publishing Company Limited

    189. Atul Kumar says:

      @ Vishnu,
      I have not seen book myself. To check if it covers certification topic, simply check index of book with exam topics for 1Z0-233 http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=41&p_org_id=1243197&lang=ZHS&p_exam_id=1Z0_233

      1Z0-235 & 1Z0-236 are core DBA topics and I don’t think 235, 236 topics are covered in detail in book you mentioned above.

    190. Vishnu says:

      Thanks for your reply,

      I want to know which path will be more fetching for a fresher to become Oracle Apps DBA 11i, considering the time factors and availablity of study materials.

      1) OCP DBA 11g -> 1z0-233
      or
      2) 1z0-235,1z0-236 -> 1z0-233

      Please suggest me.. Thanks..

    191. Atul Kumar says:

      @ Vishnu,

      My option would be 1st i.e. OCP DBA 11g -> 1z0-233

    192. Vishnu says:

      @Atul

      Thanks a lot.

      @ Sundar,
      Yes in my view this is correct time .

      You can learn on your own by picking apps dba documentation from Oracle.

      You can also join one of training institute (join one which provides hands-on practice sessions)

      Check http://focusthread.com/training

      Hi, Not everyone would take out so much time to help out people. it really is a great thing you have done,

      I’m a DBA but i also like to learn oracle apps.
      This might sound stupid but I am somehow unable to locate the guide “oracle applications concepts” in the EBS link you have posted.

      are you referring to Oracle Applications 11.5.10.2+ Online Documentation Library? Please help me out as i want to start off as soon as i can

    204. Stab_3216 says:

      got it, Thanks i will go through and let you know if i have doubts

      Hi,
      We are having oracle 9i database running in a different server machine and oracle 11i forms running in a different server machine. I like to know how these two servers are linked to each other and where the respective settings are in. We use a solaris sparc server. i used to start the database startup script first and then the startup script for forms server in the different machine. what are the settings that link the database to the forms server

      • Atul Kumar says:

        @ Karthik,
        Depending on mode in which forms is configured (Socket or Servlet) it uses TNS or think jdbc to connect from forms server to database. (connect details are in $TNS_ADMIN of Forms/Report ORACLE_HOME or in dbc file under $FND_SECURE)

    206. Karthik says:

      Thanks Atul,
      Kindly suggest me an Open source linux OS which i can install in virtual box and test all the softwares. I am well trained in unix platform. I felt ubuntu was a bit easy to use but i am not able to install any oracle software for testing as all ends up with an error

    207. Karthik says:

      Thanks atul,

      It seems my server is connected in a socket mode.
      I checked the listener.ora and tnsnames.ora. I found the following lines . are they the configuration settings that connect each other

      listener.ora

      SID_LIST_PROD =
      (SID_LIST =
      (SID_DESC =
      (GLOBAL_DBNAME= TEST)
      (ORACLE_HOME= $ORACLE_HOME)
      (SID_NAME = TEST)
      )
      (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = $ORACLE_HOME)
      (PROGRAM = extproc)
      )
      )

      tnsnames.ora

      #
      # Intermedia
      #
      extproc_connection_data =
      (DESCRIPTION=
      (ADDRESS_LIST =
      (ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROCPRD))
      )
      (CONNECT_DATA=
      (SID=PLSExtProc)
      (PRESENTATION = RO)
      ) )

      Is the ExtProc connecting both the servers. If not why are they used.

      • Atul Kumar says:

        - Install OAM as per installation guide
        – Install OID and integrate OID with OAM
        – Install OHS
        – Configure OHS as proxy (mod_wl_ohs) to forward requests to OAM
        – Install WebGate on OHS

        For time being forget about identity, policy and credential and ask query specific to installation & integration document .
