OracleWebEventProvider Class

The OracleWebEventProvider class allows ASP.NET applications to store Web events in an Oracle database.

Class Inheritance

System.Object

  System.Configuration.Provider.ProviderBase

    System.Web.Management.WebEventProvider

      System.Web.Management.BufferedWebEventProvider

        Oracle.Web.Management.OracleWebEventProvider

Declaration

// C#
public class OracleWebEventProvider: BufferedWebEventProvider

Thread Safety

All public static methods are thread-safe, although instance members are not guaranteed to be thread-safe.

Remarks

This class allows ASP.NET applications to store Web event information in an Oracle database.

Example

The following is a web.config example for an ASP.NET application that uses the OracleWebEventProvider class as the default provider. This configuration uses the connection string and default attribute values specified in the machine.config file.

Applications must provide any required configuration entries for event mapping, buffer modes, and rules in the web.config file, because the machine.config file does not provide these configuration entries. The following web.config file provides an example:

<?xml version="1.0"?>
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
  <system.web>
    <healthmonitoring enabled="true"/>
      <bufferModes>
        <add name="Notification"
             maxBufferSize="1000"
             maxFlushSize="200"
             urgentFlushThreshold="500"
             regularFlushInterval="00:00:6"
             urgentFlushInterval="00:00:03"
             maxBufferThreads="1"/>
      </bufferModes>
      <eventMappings>
        <add name="CustomEvent"
             type="CustomEventSource.CustomEvent, CustomEventSource"/>
      </eventMappings>
      <rules>
        <add name="CustomRule"
             eventName="CustomEvent"
             provider="OracleWebEventProvider"
             minInterval="00:00:00"/>
      </rules>
    </healthMonitoring>
  </system.web>
</configuration>

The following is a web.config example for an ASP.NET application that uses an OracleWebEventProvider class as the default provider, using customized settings for the connection string name and application name, and an application-specific connection string, along with other configurations as described in the previous example:

<?xml version="1.0"?>
<configuration xmlns=
  "http://schemas.microsoft.com/.NetConfiguration/v2.0">
  <connectionStrings>
    <add name="my_webevent_app_con_string" connectionString=
      "User Id=scott;Password=tiger;Data Source=Oracle"/>
  </connectionStrings>
  <system.web>
    <!-- Enable and customize OracleWebEventProvider -->
    <healthMonitoring enabled="true">
      <providers>
        <add name="CustomOracleWebEventProvider"
             type="Oracle.Web.Management.OracleWebEventProvider,
                   Oracle.Web, Version=2.112.2.0, Culture=neutral,
                   PublicKeyToken=89b483f429c47342"
             connectionStringName="my_webevent_app_con_string"
             bufferMode="CustomBufferMode">
      </providers>
      <bufferModes>
        <add name="CustomBufferMode"
             maxBufferSize="1000"
             maxFlushSize="200"
             urgentFlushThreshold="500"
             regularFlushInterval="00:00:06"
             urgentFlushInterval="00:00:03"
             maxBufferThreads="1"/>
      </bufferModes>
      <eventMappings>
        <add name="CustomEvent"
             type="CustomEventSource.CustomEvent, CustomEventSource"/>
      </eventMappings>
      <rules>
        <add name="CustomRule"
             eventName="CustomEvent"
             provider="CustomOracleWebEventProvider"
             minInterval="00:00:00"/>
      </rules>
    </healthMonitoring>
  </system.web>
</configuration>

Note that the applicationName attribute should be set to a unique value for each ASP.NET application.

The OracleWebEventProvider static methods are listed in Table 7-5.

---

OracleWebEventProvider Public Properties

The OracleWebEventProvider public properties are listed in Table 7-6.

CommandTimeout

This property gets the number of seconds that the command is allowed to execute before it is terminated with an exception.

Declaration

// C#
public int CommandTimeout {get;}
 

Property Value

An int.

Remarks

To customize a provider, ASP.NET developers can set an integer value for this property through the web.config file using the commandTimeout attribute.

The default value is 30 seconds. The attribute name in the configuration file is case-sensitive.

---

OracleWebEventProvider Public Methods

The OracleWebEventProvider public methods are listed in Table 7-7.

Initialize

This method initializes the OracleWebEventProvider instance with the property values specified in the ASP.NET application configuration file (web.config).

Declaration

// C#
public override void Initialize(string name, NameValueCollection config);

Parameters

• name

  The name of the OracleWebEventProvider instance to initialize.

• config

  A Systems.Collections.Specialized.NameValueCollection object that contains the names and values of configuration options for the OracleWebEventProvider.

Exceptions

InvalidOperationException - If the OracleWebEventProvider instance is already initialized.

ProviderException - One of the following conditions exists:

• The connectionStringName attribute in the configuration file is null or empty.

• The connection string corresponding to value of the connectionStringName attribute is null or empty.

• An unrecognized attribute is found in the configuration file.

• Another error occurs during initialization of the provider.

Remarks

The Initialize method is not intended to be called directly by the application.

ProcessEvent

This method processes the event passed to it as an argument.

Declaration

// C#
public override void ProcessEvent(WebBaseEvent eventRaised);

Parameters

• eventRaised

  The WebBaseEvent object to be processed.

Remarks

This method is called by ASP.NET applications to start event processing. If buffering is enabled, then the event is added to the buffer of events, otherwise, the event information is directly written into Oracle Database.

ProcessEventFlush

This method flushes the information passed to it as an argument.

Declaration

// C#
public override void ProcessEventFlush(WebEventBufferFlushInfo flushEvent);

Parameters

• flushEvent

  The WebEventBufferFlushInfo object that contains a collection of buffered Web events.

Remarks

This method is called by ASP.NET applications to flush all events into Oracle Database.

Shutdown

This method releases all resources.

Declaration

// C#
public override void Shutdown();

Remarks

This method is called by ASP.NET applications when the provider is unloaded. All the buffered events are first flushed into Oracle Database before the provider proceeds with shutdown.
