    Synchronize Oracle Calendar Directly from Mobile Handset
    Sunday, June 03, 2007
    Register for R12 upgrade

    Below post covers Synchronization of Oracle Calendar directly from your WAP enabled mobile handset like Nokia, Sony Ericson... This is covered in two parts , Part I covers isntallation of calendar and standalone Web (HTTP) Server and in next part II, I'll cover synchronization steps with Mobile Handset and important files.

    Traditional way of synchronizing your calendar data with your mobile handsets is via Desktop Machine (First synchronize your desktop machine with calendar server data and then synchronizing your mobile handset by connecting it to your desktop machine or laptop and vice versa).
    With mobility you need a mechnism to synchronize your calendar data directly from your handset without connecting your mobile to desktop or laptop. Today's post covers overview and implementation steps for providing infrastructure so that users/managers/employees can be in synch and update their meetings, shedules directly from mobile.

    Overview of Oracle Calendar
    Oracle Calendar is component of Oracle Collaboration Suite which you can
    install stndalone as well as part of oracle collaboration suite . Calnedar is used to book your schedule, online diaries, events and meetings.
    Below note explain implementation of Standalone Calendar so that they can be synchronized with Mobile Handset (For explanation purpose I have taken example of Nokia E61 and Nokia E50 series)
    In order to synch your mobile handset with Calendar you need standalone calendar server and HTTP Server (Oracle HTTP Server or any other web server like Apache, Webspahere...). If you installed Calendar as part of Oracle Collaboration Suite, you don't need web server as it is installed by default with Collaboration Suite.

    Overview of Standalone Oracle Calendar synch directly from Mobile Handset

    A) Install Standalone Oracle Calendar Server
    B) Install Standalone Oracle HTTP Server
    C) Configure Oracle Calendar to access via Oracle HTTP Server
    D) Upgrade Calendar to version to get Nokia E50 and E61 profiles
    E) Configuration at Nokia Handset / Mobile device
    F) Related Documentation

    Below is software and operating system I used which can vary as per your

    --Standalone calendar Server
    --Standalone Web Server (Oracle HTTP Server)

    Installed on same machine in two different oracle_home (Though you can install them on different machine as well)

    ORACLE HOME for Calendar : /apps/oracle/product/CAL
    ORACLE HOME for Oracle Web Server : /apps/oracle/product/OHS

    -- Operating System is Red Hat Linux ES 3 (Though this can be on ES4, solaris or windows as well)

    Calendar and other Software Location
    i) Standalone Calendar -> Calendar Software for Linux
    ii) Standalone Oracle HTTP Server -> Application Server Companion CD
    iii) Red Hat Linux ->

    Operating System Prereq.
    i) Make sure kernel version of Red Hat ES3 should be minimum 2.4.21-27 or higher
    ii) Install following additional RPM’s if they are not installed already. sysstat-4.0.7-4.EL.3.3

    (To check if RPM is already installed or not use "rpm -qa grep {rpm_name}" )

    iii) Add following kernel parameters in /etc/sysctl.conf
    kernel.shmall = 3279547
    kernel.shmmax = 2147483648
    kernel.shmmni = 4096
    #semaphores: semmsl, semmns, semopm, semmni
    kernel.sem = 256 32000 100 142
    fs.file-max = 327679
    net.ipv4.ip_local_port_range = 10000 65000
    kernel.msgmni = 2878
    kernel.msgmax = 8192
    kernel.msgmnb = 65535

    and execute "sysctl –p /etc/sysctl.conf" (From root user)

    iv) Add following lines in /etc/security/limits.conf
    * soft nproc 4096
    * hard nproc 16384
    * soft nofile 16384
    * hard nofile 65536 (Don't forget to put *)

    Start Standalone Calendar Installation
    Login with user "oracle" (or any other user with whom you wish to install software). Navigate to standalone calendar software location and start installation like

    i) /calendar_standalone/runInstaller

    ii) Click Next on Welcome Screen and enter ORACLE_HOME name PATH and click next.
    PATH /apps/oracle/product/CAL

    iii) Select component you wish to install and click Next, Select All Components

    iv) Select language (leave default) and click Next

    v) Select directory server you wish to use : Select Internal in our case

    vi) Enter Oracle Calendar Administrator Password (This will be used during administration and user management)

    vii) In Oracle-Calendar Node ID screen enter Node ID, since this is our first and only Node so lets make this one as Master Node with ID as 1 (Select this as Master Node)

    viii) Enter Host or Alias, Enter host name here as any thing your actual hostname of machine or virtual name like

    ix) Click Next & then click on Install Button

    On successful installation Next Step is to install Web Server (Oracle Standalone HTTP Server)

    Standalone Oracle HTTP Server Installation
    Login with username "oracle" or any other user with whom you wish to install HTTP Server. Navigate to Oracle HTTP Server software location and Start OHS Installation using runInstaller

    i) ./runInstaller

    ii) Click Next on Welcome Screen and enter ORACLE_HOME name PATH and click next
    PATH /apps/oracle/product/OHS

    iii) Select Product to Install, Select Web Server Services

    iv) Select Installation Type Select Oracle HTTP Server with Apache 2.0

    v) Select other default options till install screen

    vi) Click Next & then click on Install Button

    vii) In the end it will ask you to execute From root execute like /apps/oracle/product/OHS/

    Configure Oracle Calendar With Oracle HTTP Server
    In Order to configure Calendar via Mobile Handset, first it should be accessible via HTTP Server on HTTP/HTTPS protocol. So in this step we will configure Oracle Calendar with HTTP Server

    i) Include following files in httpd.conf of HTTP Server at

    /apps/oracle/product/CAL/ocad/config/ocad.conf and /apps/oracle/product/CAL/ocas/conf/ocal.conf

    (Here ocad.conf is Oracle Calendar Server Configuration file and ocal.conf is Oracle Calendar Application Server or OCAS configuration file)

    ii) Restart OHS as
    export ORACLE_HOME

    opmnctl stopall
    opmnctl startall (opmnctl is located in $OHS_HOME/opmn/bin directory)
    iii) Start Calendar & OCAS Server
    export ORACLE_HOME
    unistart (located in $CAL_HOME/ocal/bin)
    ocasctlstartocasctl –start –t ochecklet
    (located in $CAL_HOME/ocas/bin)

    iv) Create users and groups using Node administration Screen

    In my case during Calendar Installation, I hostname or Alias as and default HTTP Server port number during installation was 7777 so I'll access Calendar Administration Screen as

    v) Check if you can access Calendar via Web Services URL
    http://hostname.domainname:port/ocas-bin/ocas.fcgi?sub=web or

    If you get message like "Message Catalogue Unavailable" check Metalink Note # 275524.1

      Hello Atul,

      I like your document on Oracle Calendar. However, I have a question. Does the Oracle Calendar Server require a live I/P.

      As I have both Pocket PC and Nokia E50 Mobile Phone, but no live I/P. So if thats the case, I would need to purchase one.

      Since you are going to sync to calendar server via your data service provider in your case your phone service provider and they can only see public IP and not your private IP so yet you need a public IP on OCS in order to synch oracle calendar directly from mobile
