JDBC Driver Uncover
A common source of confusion for Java is that JDBC has different versions, and JDBC drivers have different types that can be used by different versions of Java. Also, the new Java specification is always under development because the related functionality is continually being extended through the J

The following articles mainly introduce the full contact of the DB2 driver types. We all know the related data access APIs provided by different versions of the database product line of IBM. It can be said that there are many data access APIs, these include early CLI-based Drivers, recent pure Java drivers, and combinations of CLI and Java.
For a specific DB2 ver
During the installation and JDBC development of DB2, you may encounter some common problems and make a record to be noted:
1. License
Whether the DB2 version is genuine or not depends on the license, but there is no prompt during the installation process. License installation:
Db2licm-A [path]/db2ese. Lic
If the license is incorrect, the biggest impact is that th
version correspondence and selection of appropriate generic drivers. fortunately, IBM has begun to unify and pay attention to ease of use. These efforts have started from DB2 UDB V7. since then, according to the JDBC driver type in the Java field, IBM has three types of drivers.
The jdbc type 2
The description of the DB2 database driver type is the main content of this article. At the same time, this article also describes the early CLI-based Drivers, recent pure Java drivers, and the combination of CLI and Java. for a specific DB2 version, the driver has a specific drive
Brief introduction
The Db2®universal database™ (UDB) JDBC driver has proven to be a powerful and IBM-supported technology. Jython is a pure Java implementation of the Python programming language.
First, we'll tell you why Jython is powerful, easy to use, and fun to write DB2 JDBC
Recently, an exception occurred when connecting to DB2 v9.5 on another machine using JDBC:
Com. IBM. db2.jcc. B. disconnectexception: encoding not supported !!

provides data access to applications through standard Java methods. JDBC is similar to DB2 CLI in that you do not have to pre-compile or compile JDBC programs. Applications compiled using JDBC only use dynamic SQL.
JDBC programming steps:
1. Establish a connection with the
The following articles mainly describe the correct operation steps for connecting JDBC to a DB2 instance and the actual operation code used for connecting JDBC to a DB2 instance, the following is a detailed description of the main content of the article. I hope you will have a better understanding of it after browsing.
For work relations, you can use DB2 and jdbcto connect to the db2java.zip package imported to the db2client.DB2 supports type2 and type4 in JDBC connection 4. The difference between them is that you need to configure the DB2 client in type2 mode.Your program will find the server correctly, and type4 will not be needed.
The method of type2 is very simple, as long
After I downgraded from Win8 to Win7, I ran the code and found an error:
Com.ibm.db2.jcc.am.SqlException: [jcc][10389][12245][4.19.26] loaded into native library db2jcct2, Java.lang.UnsatisfiedLinkError:no Db2jcct2 in Java.library.path failure
Strange, the re-installation of the system was clearly good, how can not now? Google has learned that it is called the local dynamic link library. But why would you call something local? General even the database is not the URL plus the
