IBM DB2 manual Database server configuration setup, Library file names for different platforms

￿sqlj.zip and sqlj4.zip:

These file contain classes that are required to prepare SQLJ applications for execution under the IBM Data Server Driver for JDBC and SQLJ. DB2 includes sqlj.zip in the CLASSPATH during the installation process. This file is for applications that use JDBC 3.0 and earlier functions. You have to manually include sqlj4.zip in the CLASSPATH to use JDBC 4.0 and earlier functions. Do not include both.

￿On DB2 server products that can perform Connect gateway functionality, IBM Data Server Driver for JDBC and SQLJ license files are installed and placed in the sqllib/java directory for the Linux or UNIX systems and the sqllib\java directory for the Windows systems. The license files are not required for connections to the DB2 database for Linux, UNIX, and Windows (LUW) using IBM Data Server Driver for JDBC and SQLJ Version 3.50 or later.

￿IBM Data Server Driver for JDBC and SQLJ native libraries are also installed to support Type 2 connectivity. These are placed in the sqllib/lib directory for Linux and UNIX systems, or the sqllib\bin directory for Windows systems.

Table 4-2shows the library file names for different platforms.

Database server configuration setup

To allow successful application connection to a DB2 database with IBM Data Server Driver for JDBC and SQLJ, check these settings in the database server:

￿Remote client connectivity:

In general, the DB2 database should be already configured to allow remote access.

Follow this procedure to configure the database for remote client access:

a.Check if TCP/IP is already enabled using the following command: db2set -all

Check if DB2COMM=TCPIP is presented in the output. If it is not already present, set the environment variable DB2COMM to TCPIP:

db2set DB2COMM=TCPIP
