| <div class="sectionbody"> |
| <div class="sect2"> |
| <h3 id="data-sources">3.1. Data Sources</h3> |
| <div class="paragraph"> |
| <p>The term <strong>data source</strong> logically refers to a database or other data |
| storage entity. A JDBC (client) data source is physically a Java object that |
| contains properties such as the URL of the physical database, the |
| catalog to use when connecting to this database, and the schema to use |
| when connecting to this database. The JDBC data source also contains |
| methods for obtaining a JDBC connection to the underlying database.</p> |
| </div> |
| <div class="sect3"> |
| <h4 id="jdbc-data-source-client-side">3.1.1. JDBC Data Source (client-side)</h4> |
| <div class="paragraph"> |
| <p>All JDBC data source classes implement either the <code>javax.sql.DataSource</code> |
| interface or the <code>javax.sql.ConnectionPoolDataSource</code> interface. The Type |
| 4 driver data source classes are <code>org.trafodion.jdbc.t4.TrafT4DataSource</code> and |
| <code>org.trafodion.jdbc.t4.TrafT4ConnectionPoolDataSource</code>. (These classes are |
| defined by the JDBC 3.0 specification.)</p> |
| </div> |
| <div class="paragraph"> |
| <p>Typically, a user or system administrator uses a tool to create a data |
| source, and then registers the data source by using a JNDI service |
| provider. At run time, a user application typically retrieves the data |
| source through JNDI, and uses the data source’s methods to establish a |
| connection to the underlying database.</p> |
| </div> |
| <div class="paragraph"> |
| <p>A DataSource object maps to an instance of a database. In the Type 4 |
| driver product, the DataSource object acts as an interface between the |
| application code and the database and enables connection with a DCS |
| (Data Connectivity Services) data source.</p> |
| </div> |
| </div> |
| </div> |
| <div class="sect2"> |
| <h3 id="security">3.2. Security</h3> |
| <div class="paragraph"> |
| <p>Clients connect to the Trafodion platform with a valid user name |
| and password, using standard JDBC 3.0 APIs. An application can make multiple |
| connections using different user IDs, and creating different Connection |
| objects.</p> |
| </div> |
| <div class="paragraph"> |
| <p>The Type 4 driver provides for user name and password authentication. |
| The password is encrypted.</p> |
| </div> |
| <div style="page-break-after: always;"></div> |
| </div> |
| <div class="sect2"> |
| <h3 id="connection-by-using-the-datasource-interface">3.3. Connection by Using the DataSource Interface</h3> |
| <div class="paragraph"> |
| <p>The <code>javax.sql.DataSource</code> interface is the preferred way to establish a |
| connection to the database because this interface enhances the application |
| portability. Portability is achieved by allowing the application to use a |
| logical name for a data source instead of providing driver-specific information |
| in the application. A logical name is mapped to a <code>javax.sql.DataSource</code> |
| object through a naming service that uses the Java Naming and Directory |
| Interface (JNDI). Using this DataSource method is particularly recommended |
| for application servers.</p> |
| </div> |
| <div class="paragraph"> |
| <p>When an application requests a connection by using the <code>getConnection</code> method |
| in the <code>DataSource</code>, then the method returns a <code>Connection</code> object.</p> |
| </div> |
| <div class="paragraph"> |
| <p>A <code>DataSource</code> object is a factory for <code>Connection</code> objects. An object that |
| implements the <code>DataSource</code> interface is typically registered with a JNDI |
| service provider.</p> |
| </div> |
| <div class="sect3"> |
| <h4 id="overview-of-tasks-to-deploy-datasource-objects">3.3.1. Overview of Tasks to Deploy DataSource Objects</h4> |
| <div class="paragraph"> |
| <p>Before an application can connect to a <code>DataSource</code> object, typically |
| the system administrator deploys the <code>DataSource</code> object so that |
| the application programmers can start using it.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Data source properties are usually set by a system administrator using |
| a GUI tool as part of the installation of the data source. Users to |
| the data source do not get or set properties. Management tools can get |
| at properties by using introspection.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Tasks involved in creating and registering a database object are:</p> |
| </div> |
| <div class="olist arabic"> |
| <ol class="arabic"> |
| <li> |
| <p>Creating an instance of the <code>DataSource</code> class.</p> |
| </li> |
| <li> |
| <p>Setting the properties of the <code>DataSource</code> object.</p> |
| </li> |
| <li> |
| <p>Registering the <code>DataSource</code> object with a naming service that uses |
| the Java Naming and Directory Interface (JNDI) API.</p> |
| </li> |
| </ol> |
| </div> |
| <div class="paragraph"> |
| <p>An instance of the <code>DataSource</code> class and the <code>DataSource</code> object |
| properties are usually set by an application developer or system |
| administrator using a GUI tool as part of the installation of the |
| data source. If you are using an installed data source, then see |
| <a href="#programmatically-creating-an-instance-of-the-datasource-class">Programmatically Creating an Instance of the DataSource Class</a>.</p> |
| </div> |
| <div class="paragraph"> |

| pooling. The SQL executor automatically recompiles queries when certain conditions are met. |
| Some of these conditions are:</p> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>A run-time version of a table has a different redefinition timestamp |
| than the compile-time version of the same table.</p> |

| <p>An existing open operation on a table was eliminated by a DDL or SQL |
| utility operation.</p> |

| <p>The transaction isolation level and access mode at execution time is |
| different from that at the compile time.</p> |
| </li> |
| </ul> |
| </div> |
| </li> |
| <li> |
| <p>When a query is recompiled, then the SQL executor stores the recompiled query; |

| are met again.</p> |
