OracleSessionStateStore Class The OracleSessionStateStore class allows ASP.NET applications to store session information in an Oracle database. Class Inheritance System.Object System.Configuration.Provider.ProviderBase System.Web.SessionState.SessionStateStoreProviderBase Oracle.Web.SessionState Declaration // C# public class OracleSessionStateStore : SessionStateStoreProviderBase 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 and manage session state information in an Oracle database.Note that the session information that this provider manages is application session information, not database session information. Expired session data is periodically deleted from the database. Example The following is a web.config example for an ASP.NET application that uses OracleSessionStateStore as the default provider with customized settings and an application-specific connection string: Requirements Namespace: Oracle.Web.SessionState Assembly: Oracle.Web.dll Microsoft .NET Framework Version: 2.0 or later See Also: "Oracle Providers for ASP.NET Assembly" OracleSessionStateStore Members OracleSessionStateStore Constructors OracleSessionStateStore Public Methods OracleSessionStateStore Public Properties OracleSessionStateStore Members OracleSessionStateStore members are listed in the following tables.

See Also: "Oracle Providers for ASP.NET Assembly" OracleSessionStateStore Class OracleSessionStateStore Members OracleSessionStateStore Public Methods The OracleSessionStateStore public methods are listed in Table 5-5. Table 5-5 OracleSessionStateStore Public Methods Public Methods Description CreateNewStoreData Creates a new SessionStateStoreData object for the current request CreateUninitializedItem Adds a new session state item to the database Dispose Releases all the resources for this instance EndRequest Allows the OracleSessionStateStore object to perform any cleanup that may be required for the current request GetItem Returns a read-only session item from the database GetItemExclusive Locks and returns a session item from the database Initialize Initializes the provider with the property values specified in the ASP.NET application configuration file InitializeRequest Performs any per-request initializations that the OracleSessionStateStore provider requires ReleaseItemExclusive Releases the lock on a session item in the database, if multiple attempts to retrieve the session item fail RemoveItem Removes the specified session item from the database ResetItemTimeout Resets the expiration date and timeout for a session item in the database SetAndReleaseItemExclusive Updates the session time information in the database with the specified session item and releases the lock SetItemExpireCallback Returns a false value to indicate that callbacks for expired sessions are not supported See Also: "Oracle Providers for ASP.NET Assembly" OracleSessionStateStore Class OracleSessionStateStore Members CreateNewStoreData This method creates a new SessionStateStoreData object for the current request. Declaration // C# public override SessionStateStoreData CreateNewStoreData(HttpContext context, int timeout); Parameters context The HttpContext object for the current request. timeout The timeout value for the SessionStateStoreData object that is created. Return Value A new SessionStateStoreData object for the current request. Remarks This method creates a new SessionStateStoreData object for the current request based on the HttpContext and timeout values. The SessionStateModule calls this method at the beginning of a request for an ASP.NET page, if the request does not contain a session ID or if the request contains a session ID for a session that is not found in the database. This method creates a new SessionStateStoreData object with an empty ISessionStateItemCollection object, an HttpStaticObjectsCollection collection, and the specified timeout value. See Also: "Oracle Providers for ASP.NET Assembly" OracleSessionStateStore Class OracleSessionStateStore Members CreateUninitializedItem This method adds a new session state item to the database. Declaration // C# public override void CreateUninitializedItem(HttpContext context, string id, int timeout); Parameters context The HttpContext object for the current request. id The session ID for the current request. timeout The timeout value for the current request. Exceptions ArgumentNullException - The input parameter is null. OracleException - An Oracle-related error has occurred. Remarks This method adds an uninitialized session state entry into the database and is called when the cookieless and regenerateExpiredId attributes are both set to true. After a new session ID is created, this method is called to store an uninitialized entry with this new session ID in the database. The browser is redirected to the URL containing the new session ID. The new session ID exists in the database, so there is no conflict with an expired session ID. See Also: "Oracle Providers for ASP.NET Assembly" OracleSessionStateStore Class OracleSessionStateStore Members Dispose This method releases all the resources for this instance. Declaration // C# public override void Dispose(); Remarks This method releases all the resources for this instance when the application domain is closed. See Also: "Oracle Providers for ASP.NET Assembly" OracleSessionStateStore Class OracleSessionStateStore Members EndRequest This method allows the OracleSessionStateStore object to perform any cleanup that may be required for the current request. Declaration // C# public override void EndRequest(HttpContext context); Parameters context The HttpContext object for the current request. Remarks This method is called by the SessionStateModule object at the end of a request. See Also: "Oracle Providers for ASP.NET Assembly" OracleSessionStateStore Class OracleSessionStateStore Members GetItem This method returns a read-only session item from the database. Declaration // C# public override SessionStateStoreData GetItem(HttpContext context, string id, out bool locked, out TimeSpan lockAge, out Object lockId, out SessionStateActions actions); Parameters context The HttpContext object for the current request. id The session ID for the current request. locked A Boolean value that is true if the session item is locked in the database; otherwise, it is false. lockAge A a TimeSpan object that indicates the amount of time the session item has been locked in the database. lockId A lock identifier object. actions A SessionStateActions enumeration value that indicates whether or not the session is uninitialized and cookieless. Return Value A SessionStateStoreData object that contains session information from the database. Exceptions ArgumentNullException - The input parameter is null. OracleException - An Oracle-related error has occurred. System.Configuration.Provider.ProviderException - The session state information is invalid and might be corrupted. Remarks This method returns a read-only SessionStateStoreData object from the database and updates the expiration date of the session item. This method is called by the session state service at the beginning of a request. It is called only if the EnableSessionState attribute in the page is set to ReadOnly. If no session data is found, then the locked out parameter is set to false and a null reference is returned. The session state service then calls the CreateNewStoreData method to create a new session item in the database. If the session data is locked in the database, then the locked out parameter is set to true, the lockAge parameter is set to the amount of time the session item has been locked in the database, the lockId parameter is set to the lock identifier and a null reference is returned. The session state service then keeps calling this method at half-second intervals. If the lockAge value exceeds the HttpRuntimeSection.ExecutionTimeout value, then the session state service calls the ReleaseItemExclusive method to release the lock. It then calls the GetItem method again. See Also: "Oracle Providers for ASP.NET Assembly" OracleSessionStateStore Class OracleSessionStateStore Members GetItemExclusive This method locks a session item and returns it from the database. Declaration // C# public override SessionStateStoreData GetItemExclusive(HttpContext context, string id, out bool locked, out TimeSpan lockAge, out Object lockId, out SessionStateActions actions); Parameters context The HttpContext object for the current request. id The session ID for the current request. locked A Boolean value that is true if the session item was successfully locked in the database; otherwise, it is false. lockAge A TimeSpan object that indicates the amount of time the session item has been locked in the database. lockId A lock identifier object. actions A SessionStateActions enumeration value that indicates whether or not the session is uninitialized and cookieless. Return Value A SessionStateStoreData object that contains session information from the database. Exceptions ArgumentNullException - The input parameter is null. OracleException - An Oracle-related error has occurred. System.Configuration.Provider.ProviderException - The session state information is invalid and might be corrupted. Remarks This method returns a SessionStateStoreData object from the database and updates the expiration date of the session item. This method is called only if the attribute in the page is set to the default value of true. The session item is retrieved only if no other requests are currently using it. The session item in the database is locked for the duration of the request. If no session data is found, the locked out parameter is set to false and a null reference is returned. The session state service then calls the CreateNewStoreData method to create a newsession item in the database. If the session data is locked in the database, then the locked parameter is set to true, the lockAge parameter is set to the amount of time the session item has been locked in the database, the lockId parameter is set to the lock identifier and a null reference is returned. The session state service then keeps calling this method at half-second intervals. If the lockAge value exceeds the ExecutionTimeout value, then the session state service calls the ReleaseItemExclusive method to release the lock. It then calls the GetItemExclusive method again. See Also: "Oracle Providers for ASP.NET Assembly" OracleSessionStateStore Class OracleSessionStateStore Members Initialize This method initializes the provider 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 provider instance to initialize. config A Systems.Collections.Specialized.NameValueCollection object that contains the names and values of configuration options for the provider. Exceptions ArgumentNullException - The config parameter is null. System.Configuration.Provider.ProviderException - The connectionStringName attribute is empty or does not exist in the configuration file, or an invalid attribute is found in the configuration file. Remarks The Initialize method is not intended to be called directly by the application.

Declaration // C# public override void InitializeRequest(HttpContext context); Parameters context The HttpContext object for the current request. Exceptions ArgumentNullException - The context parameter is null. Remarks This method is called by the session state service before calling any other methods. See Also: "Oracle Providers for ASP.NET Assembly" OracleSessionStateStore Class OracleSessionStateStore Members ReleaseItemExclusive This method forcibly releases the lock on a session item in the database, if multiple attempts to retrieve the session item fail. Declaration // C# public override void ReleaseItemExclusive(HttpContext context, string id, Object lockId); Parameters context The HttpContext object for the current request. id The session ID for the current request. lockId The lock identifier for the current request. Exceptions ArgumentNullException - The input parameter is null. OracleException - An Oracle-related error has occurred. Remarks This method is called by the session state service to release the lock on a session item in the database and update the expiration date. The SessionStateModule calls this method at the end of a request if the session values are unchanged or when the lock has exceeded the HttpRuntimeSection.ExecutionTimeout property value. See Also: "Oracle Providers for ASP.NET Assembly" OracleSessionStateStore Class OracleSessionStateStore Members RemoveItem This method removes the specified session item from the database. Declaration // C# public override void RemoveItem(HttpContext context, string id, Object lockId, SessionStateStoreData item); Parameters context The HttpContext object for the current request. id The session ID for the current request. lockId The lock identifier for the current request. item The session item to remove from the database.

See Also: "Oracle Providers for ASP.NET Assembly" OracleSessionStateStore Class OracleSessionStateStore Members ResetItemTimeout This method resets the expiration date and timeout for a session item in the database. Declaration // C# public override void ResetItemTimeout(HttpContext context, string id); Parameters context The HttpContext object for the current request. id The session ID for the current request. Exceptions ArgumentNullException - The input parameter is null. OracleException - An Oracle-related error has occurred. Remarks The session state service calls this method to reset the expiration date and timeout for a session item in the database, to the current date and time. See Also: "Oracle Providers for ASP.NET Assembly" OracleSessionStateStore Class OracleSessionStateStore Members SetAndReleaseItemExclusive This method updates the session time information in the database with the specified session item, and releases the lock. Declaration // C# public override void SetAndReleaseItemExclusive(HttpContext context, string id, SessionStateStoreDataItem item, Object lockId, bool newItem); Parameters context The HttpContext object for the current request. id The session ID for the current request. item The session item containing new values to update the session item in the database with. LockId The lock identifier for the current request. newItem A Boolean value that indicates whether or not the session item is new in the database. A false value indicates an existing item. Exceptions ArgumentNullException - The input parameter is null. OracleException - An Oracle-related error has occurred. Remarks If the session items have been modified, the session state service calls this method at the end of a request, to either create a new item or update an existing session item in the database with the provided session values. This method also updates the expiration time for the session item and releases the lock on the session data. See Also: "Oracle Providers for ASP.NET Assembly" OracleSessionStateStore Class OracleSessionStateStore Members SetItemExpireCallback This method returns a false value to indicate that callbacks for expired sessions are not supported. Declaration // C# public override bool SetItemExpireCallback(SessionStateItemExpireCallback expireCallback); Parameters expireCallback The delegate for the Session_OnEnd event defined in the Global.asax file.
