This is the preferred method for database accesses using the Sun ONE Application Server because it enables you to take advantage of the transaction control built into EJB components and their containers. Specifies the number of connections to be destroyed if the existing number of connections is above the Steady Pool Size subject to the Max Pool Size limit. Because you use EJB components as building blocks for many applications with little or no changes, you can use an EJB component to maintain a common interface to your EIS database. You can select Other if your database driver is not listed. I’m sure you could change that. List of all programming commands? For details, see “Creating a Connection Pool”.

An idle connection is one that has not been used for a period specified by Idle Timeout. Then you can use this driver even if your host environment has other ones i. If you want to enable global transactions, check the Global Transaction Support box. For example, most database vendors support most of the SQL-3 language, but no vendor provides fully unqualified support for all of the SQL-3 standard.
Specifies the amount of time, in milliseconds, jdbcc3 the caller is willing to wait to acquire a connection.
Specifies the database server for this connection pool. The JDBC specification is a broad, database-vendor-independent set of guidelines.
This method returns false if the connection is open, and returns true only after Connection. User – Set as appropriate. Your Database Vendor selection determines what is displayed when you click the Next button. Put the jdbc3 driver into a folder and write a class loader that only loads from that folder. Using The Command Line Interface. Most vendors built SQL-3 support on top of their existing proprietary relational database management systems, and either those proprietary systems offer features not in SQL-3 or SQL-3 offers features not available in those systems.
Select the name of the connection pool you configured.

Force java 7 to only use JDBC 3. Always reestablish connections before continuing database operations after you call Connection.
Connections are shared only if res-sharing-scope is set to Shareable in the J2EE deployment descriptor. Specifies the table name to be used to perform a query to validate a connection. Connections are not automatically closed; an application must close its connections. Name required – Enter a name or ID for jrbc3 connection pool.
At the time the JDBC 2. The JDBC API lets you write high-level, easy-to-use programs that operate seamlessly with jdhc3 across many different databases without requiring you to know most of jdbd3 low-level database implementation details. Dirty reads, non-repeatable reads and phantom reads are prevented. Specify or examine the transaction isolation level for a connection using the Connection. These jxbc3 can be used to describe how pooledConnection objects created by DataSource objects should be pooled.
Because the drivers and databases supported by the Sun ONE Application Server are constantly being updated, and because database vendors continue to upgrade their products, always check with Sun technical support for the latest database support information.
