HOBLink J-DRDA
|
The introduction of the JDBC database interface represents a significant enhancement to the Java programming language. Building on Java’s pioneering platform independence, JDBC now enables you to access non-proprietary databases in heterogeneous environments.
HOBLink J-DRDA also includes the database query tool J-DBrowser.
HOBLink J-DRDA is written in “100% pure Java” and adheres to the Java strategy of “write once, run anywhere,” meaning it will run on any Java platform. The certification guarantees reliable access to all Java applications and Java applets that support JDBC. The JDBC Type 4 driver can be loaded via a web server or installed locally.
A central database is the heart of every modern enterprise. Thanks to HOBLink J-DRDA, you can make central databases accessible to every user, even in a heterogeneous IT environment. HOBLink J-DRDA is a JDBC Type 4 driver that allows database connectivity to DB2 databases over any TCP/IP network. Via the JDBC interface, HOBLink J-DRDA offers all modern web browsers and Java environments access to the databases. Thanks to its optimized performance, HOBLink J-DRDA allows direct access via Internet, Intranet or Extranet without installing any proprietary middle-ware.
The web-based HOBLink J-DRDA solution can be installed and configured in a very short time - keeping costs to a minimum.
The J-DBrowser, a user-friendly database query tool with a graphical user interface, is included at no extra cost with HOBLink J-DRDA . It is based on JDBC and requires a JRE 1.2 (Java Runtime Environment) or higher, or Java Swing in addition to the JDBC driver. Database queries can be generated, stored and run with a few mouse clicks in the easy-to-use GUI. Additionally, J-DBrowser also supports the conventional entry of complex SQL commands, whereby J-DBrowser provides all the tools the administrator needs to bundle and save complex queries into batch routines (running in batch mode).
HOBLink J-DRDA supports the security features of the Java architecture. The digital signature guarantees the security of the loaded Java applets. The authorization mechanism of the host account and the database can still be used, e.g., read or write access for authorized users. With the addition of the HOBLink Secure package, all the data which HOBLink J-DRDA sends over the Internet can be protected with up to 256-bit encryption.
With HOBLink J-DRDA, any commercially available Java program that supports the JDBC interface can be used for data maintenance. Programs developed by users can access HOBLink J-DRDA via the JDBC 3.0 API . For example, development is possible with:
Host databases can also be accessed via SNA, if, for example, you have no TCP/IP connection or if DRDA via TCP/IP is not supported by DBMS. This is made possible by the “HOB Database Gateway Extension.” This gateway extension provides connections to the DB2/VM, DB2/VSE and DB2/400 database systems.
HOBLink J-DRDA runs on every Java-capable platform that supports JDK 1.1.
Note:
HOBLink J-DRDA supports JDBC 2.0 with the following exceptions (both of these points cannot be implemented using the DRDA protocol).
- Freely positionable cursor (scrollable ResultSets)
- Programmatic updates (updatable ResultSets)
The following Advanced (SQL3) Data Sets are also not supported at this time:
- ARRAY
- REF, UDT (user defined types), LOCATOR
The BLOB and CLOB Advanced (SQL3) Data Sets are also supported.
HOBLink J-DRDA offers reliable, high-performance database connectivity to the following:
Additionally supported if the HOB Database Gateway Extension is used:
