Jdbc Update Query In Tibco Spotfire' title='Jdbc Update Query In Tibco Spotfire' />At the end of this chapter you will be able to Describe the high level architecture of JDBCList the four driver types, and those provide by WLSDescribe and configure Data Sources Use the Administration Console to manage JDBC resources.What Is JDBC JDBC is an API for uniformly accessing databases.JDBC provides Platform independent access to databases.Location transparency.Transparency to proprietary database issues.Support for both two tier and multi tier models for database access.JDBC Architecture.JDBC Drivers Type 1 Driver.The Type 1 driver Is a JDBC ODBC bridge.Usually, runs on Windows.Requires ODBC driver to be installed on client machine.While working with TIBCO projects dealing certain database operations we have a choice either to use JDBC activities from the JDBC Palette or we can go for.Download the free trial version below to get started.Doubleclick the downloaded file to install the software.In this tutorial you will learn about a brief overview, architecture, Modular Configuration and Deployment in jdbc environment.Type 2 Drivers.The Type 2 driver Requires a native driver to be already installed on the client machine.The driver converts JDBC calls to native API calls of the database.Type 3 Drivers.A network server can apply several techniques to boost performance Connection Pooling.Jdbc Update Query In Tibco Spotfire' title='Jdbc Update Query In Tibco Spotfire' />In TIBCO BW Proceeses, you can use JDBC Call Procedure activity to call a Stored Procedure in a database to perform any type of actions.In this tutorial, I.Load management.

Type 4 Drivers.Type 4 drivers are all Java driver implementations that do not require client side configuration.Two Tier Architecture.In the two tier model, a Java application communicates directly with the DBMS.A JDBC driver is needed that can communicate directly with the DBMS.This is a clientserver configuration.Multi Tier Architecture.In the multi tier model, commands are sent to a middle tier of services, which then sends the commands to the DBMS.The DBMS processes the commands and sends the results back to the middle tier, which then sends them to the client.Choosing the Correct Driver.Choosing the correct driver can have a significant impact on performance.For two tier applications use the type 1, 2 or 4 driver specific to the DBMS you are using.For multi tier applications use Data Source lookup in a client class.A type 1, 2 or 4 drivers on the server, specific to the DBMS you are using.XA driver where transaction support is required.Data Sources What Is a Data SourceA Data Source object provides a way for a JDBC client to obtain a database connection from a connection pool.A Data Source Is stored in the WLS JNDI tree.Can support transactions.Is associated with a connection pool.What Is a Connection Pool A connection pool is a group of ready to use database connections associated with a Data Source.Connection pools Are created at Web.Logic Server startup.Can be administered using the Administration Console.Can be dynamically resized to accommodate increasing load.Benefits of Data Sources and Connection Pools.Some advantages of this approach are Time and overhead are saved by using an existing database connection.Connection information is managed in one location in the Administration Console.The number of connections to a database can be controlled.The DBMS can be changed without the application developer having to modify underlying code.A connection pool allows an application to borrow a DBMS connection.JDBC Data Source Architecture.Modular Configuration and Deployment of JDBC Resources.JDBC configurations in WLS are stored in XML documents All JDBC configurations must conform to the new weblogic jdbc.IDEs and other tools can validate JDBC modules based on the schema.You create and manage JDBC resources either as system modules or as application modules.JDBC application modules are a WLS specific extension of J2.EE modules and can be deployed either within a J2.EE application or as stand alone modules.How Data Sources Are Used.A client retrieves a Data Source through JNDI lookup and uses it to obtain a database connection.Creating a JDBC Data SourceCreating a Data Source Properties.Creating a Data Source XA Options.Creating a Data Source Connection.Properties.Creating a Data Source Test Database Connections Select Targets Configuring a Connection PoolConnection Pool Checklist.Download Do Gta Vice City Stories Para Pc Baixaki Programas there.You can modify a connection pool after the Data Source has been created.Before modifying a connection pool, you should understand The JDBC URL of the database.The connection properties used to authenticate a user or optionally configure the driver.Ask your DBA for The maximum number of connections your application will be allowed.JDBC URLs.Database locations are specified using a JDBC Uniform Resource Locator URL.Examples Multi Data SourcesMulti Data Source It is an abstraction around a group of data sources.Determines which data source to use to satisfy the request depending on the algorithm selected in the multi data source configuration Load balancing Or Failover.Are bound to the JNDI tree.XA Support for Multi Data Sources.The WLS JDBC supports using Multi Data Sources in XA transactions.You can configure the data sources contained within the Multi Data Source to use XA JDBC drivers.Monitoring Testing Data Sources.Monitoring Data Sources Statistics.The Administration console provides two types of data source monitoring statistics and testing.Monitoring Data Sources Testing.The Administration console provides a mechanism for manually testing individual data sources.Summary In this chapter we discussed JDBC high level architecture.Web.Logic Server provided JDBC driver types.Data Source definition and workings.Connection pool definition and workings.Managing JDBC resources with the Administration Console.Summary.Reviewer.Vijay.
