NAME

Siebel::COM::App::DataServer - Perl extension for connecting to a Siebel COM Data Server environment

SYNOPSIS

   $sa = Siebel::COM::App::DataServer->new(
        {
            cfg         => $cfg,
            data_source => $datasource,
            user        => $user,
            password    => $password
        }
    );

    my ( $bo, $bc, $key, $field, $moreResults );

    $sa->login();

    foreach $key ( keys(%$schema) ) {

        $bo = $sa->get_bus_object($key);
        $bc = $bo->get_bus_comp($key);

        foreach $field ( @{ $schema->{$key} } ) {

            $bc->activate_field($field);

        }

        $bc->clear_query();
        $bc->query();

DESCRIPTION

Siebel::COM::App::DataServer is a subclass of Siebel::COM::App, providing access to the Siebel COM Data Server environment as well as additional functionality.

Additionally to all architecture differences from Siebel::COM::App::DataControl, this class have important difference about error treament: all method calls requires a Win32::OLE::Variant to be passed as a parameter for error checking, so all those procedures are executed internally.

To be able to do that, almost all methods inherited from Siebel::COM::App are overloaded or overrided and a specific role (Siebel::COM::Exception::DataServer) is applied.

Usually using Siebel::COM::App::DataControl is preferable since it is faster to load and execute and can multiplex connections to a Siebel Enterprise, but DataServer still have it's specific uses:

  1. Provides CRUD operations in the Siebel Client local database.

  2. Avoid object restrictions in the Siebel Repository by using a local modified SRF.

  3. Avoid security restrictions applied to the Siebel Enterprise, like firewalls and authentication.

ATTRIBUTES

cfg

The complete path to the Siebel application configuration file. Required.

datasource

The datasource name as described in the file of cfg attribute.

ole_class

Differently from the superclass, this attributes defaults to "SiebelDataServer.ApplicationObject". You probably don't want to change that, so this attribute is not required during object creation.

get_bus_object

Overrided from superclass.

Expects a Business Object name as parameter.

Returns a Siebel::COM::Business::Object::DataServer object. If the Business Object name does not exists in the repository, an exception is raised.

METHODS

BUILD

Additionally to the superclass operations, this method will call the load_objects method automatically.

get_app_def

Returns a string as expected by the LoadObjects COM method from the ole_class. It will validate if the cfg can be read and will raise and exception in the case it cannot.

load_objects

Same as COM LoadObjects method, but adding the proper error checking.

EXPORT

None by default.
