    Autoconfig Basics
    Wednesday, October 04, 2006
    Register for R12 upgrade
    I am getting lots of request for Autoconfig so I thought lets start with this most powerful tool (in my views) in Oracle Apps .

    What is Autoconfig ?
    Autoconfig is tool in Apps to configure oracle Applications 11i , Application Tier as well Database Tier.

    How to run Autoconfig ?
    If you want to configure database tier then you have to execute autoconfig script adautocfg.sh on database tier else if you want to configure on application tier (Middle Tier ) then you have to execute one on middle tier .

    Here is the script location
    For Database tier its $ORACLE_HOME/appsutil/scripts/$CONTEXT_NAME
    For Application Tier its $OAD_TOP/admin/scripts/$CONTEXT_NAME

    adautocfg.sh calls adconfig.sh from $AD_TOP/bin which inturn calls adconfig.pl from $AD_TOP/bin

    Don't forget to take backup before executing autoconfig.

    What source of information for Autoconfig to update configuration files ?
    If you are wondering where is configuration information stored about your apps 11i instance based on which it updates your Instance then this file is xml file also called as Context file and its in $APPL_TOP/admin for Application Tier or $ORACLE_HOME/appsutil in Database Tier

    I am going to unwrap this xml / context file which is most important file . If you get a chance open this file & go through it so wait for my next post on Context File Contents with explanation & how to put your customization so that Autoconfig can't overwrite them ..

      Hi jeremiah,

      Atul,
      Nice post.
      By the way, it should be AD_TOP/bin instead of FND_TOP/bin.

      Suresh,
      you Just take backup of xml file . (If you are new to autoconfig & not very good in apps you might want to backup middle tier & database ) but if you know how to troubleshoot in case of any issues then no need to backup middle tier & database .

      Sandeep,
      I am happy to hear that you would like to hear more on XML file .

      Hi,
      We are planning to change the apps password in our production. Usuallly i use to change the apps password using FNDCPASS and run autoconfig to probagate the password change. But now my client dont want to run the autoconfig after password change. I know we can do this by changing some config files. Can you please give info about what configuration files we should change the passwords in 11.5.10.2

    • At 7:01 PM, Blogger Atul Kumar said…

      Iac,
      You don't have to run Autoconfig after changing apps password , you just need to update wdbsvr.app ($IAS_ORACLE_HOME/Apache/modplsql/conf)

      You have to bounce CM after password change.

      If you have any custom file in which you store apps password likle startup shutdown script , change there as well.

    • At 10:14 PM, Anonymous Chandramohan said…

      You don't need to take the backup before running Autoconfig. Since the tool automatically creates a backup in $APPL_TOP/sid_hostname/out directory with the directory name being a time stamp. Just open that directory and run rollback.sh . This will put the system into a status prior to the current Autoconfig run.

       
    • At 10:21 PM, Blogger Atul Kumar said…

      Thanks Chandramohan for sharing this information with us.

      Hi Atul & Chandra,

      This is my first comment in this site so I am a new kid for all, but not so new for oracle apps DBA world.

      Just seeing the content for apps DBA and would like to add my comments whenever I have time..

      The location and name of the file stated here for rollback of autoconfig should be:

      $APPL_TOP/admin/sid_hostname/out
      /date_time_etc/restore.sh

      Please correct me if I am not looking at the right file/directory.

      Thanks,

      KK

      KK & Chandra ,
      Thanks for your feedback & suggestions .

      Here is the actual location

      Hi atul...
      This is kiran from Hyderabad. Actually i'm a senior lecturer in Physics. As i got bored off in teaching for 8 years, i have chosen Apps DBA to learn. Before that i have learnt Core DBA, but not upto the mark in the subject. Now i'm learning Apps DBA and can i get job being a novice to this field? Pl suggest me in what way i have to read? I'm unable to remember the file locations in different Tiers. Could you pl help me out? Thankyou...

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

      Hi Kiran,
      You focus on basics and architecture. Don't worry about files initially as long as you knoiw where to find in documentation. You will remeber these file names & location once you start actually working on issues & supporting apps

      Hi, Atul:

      Hi Atul,

      Iam Kumar from hyd.Iam working on production instance,so how can i autoconfig run without stop the applications services.

       
    • At 6:50 AM, Anonymous Kumar said…

      Hi Atul,
      We can edit the .xml file? when run the autoconfig,what is the back end processes.how .xml file update and read that time.

       
    • At 9:20 AM, Blogger ankush said…

      hi

      running a autoconfig is safe or it can create issues . do we need to bring down the apps tier for it . Wat really it does it just creates context files or it really updates the instance as well
      regards

       
    • At 12:57 PM, Blogger Atul Kumar said…

      Autoconfig will configure your system as per entry in context file SID_hostname.xml in APPL_TOP/admin . Autoconfig will make cahnges so if you are not confortable then better take backup before running it. There is option to run autoconfig in precheck mode to see what all files and configurations its going to change. For this option check Autoconfig FAQ in metalink

       
    • At 5:21 PM, Anonymous Anonymous said…

      Atul, I need to change the topic a bit and this is a major task. I am a newbee to Oracle Application. We have upgraded our Appliction from 11.5.4 to 11.5.10 as well as the platform from Sun Solaris to Dell Serveers running Linux ES4. Now we are running a number of tests at the moment and I was wondering if you could help with just simple cold backup scripts backing everything to tape. What I am asking is not the Linux commands in backing up but just what your simple approach will be in taking a cold backup to tape.

      These are my mount points.......
      /
      /boot
      /dev/shm
      /home
      /tmp
      /usr
      /var
      /u01
      /u02
      /u03

      Thanks.

       
    • At 8:56 PM, Blogger Atul Kumar said…

      Shutdown application tier and database.

      Identity mount point where your application tier and database tier files including data files exists and copy them to tape using tape libbary commands.

      Hi Atul,

      Can u pls tell me why Autoconfig is required before running adpreclone, even if we know that our source system is in its updated form? Is it necessary for cloning?

       
    • At 7:12 PM, Blogger NarenderSingh said…

      Atul,

      This is the first time I am responding to your blog. Just wanted to add on a cooment of changing APPS password without running autoconfig.

      New APPS password must be updated in two files
      $IAS_ORACLE_HOME/Apache/modplsql/cfg/wdbsvr.app on mid tier
      and
      $ORACLE_HOME/reports60/server/CGIcmd.dat on admin tier

      Also we need to bounce CM and Mid Tier services (Apache/forms) to avoid any issues during runtime.

      Thanks
