Chapter 5. Configuring Host and AS/400 Databases for DB2 Connect This section describes the steps requir ed to configur e host and AS/400 database servers to accept connections from DB2 Connect workstations.
Many details of these steps have changed with the introduction of DB2 Universal Database for OS/390 V ersion 5.1. Most of these steps apply to SNA users, but some also apply to users who will connect to DB2 Universal Database for OS/390 via TCP/IP .
Sample Network Element Names (VT AM) Figure 9 shows the sample VT AM definitions used to configure a host database server . Sample VT AM APPL Definition for OS/390 Figure 10 on page 42 shows the sample VT AM application major node definitions. In most cases, such a definition will already exist with a dif fer ent LU name.
Note: Continuations must begin in column 16, with continuation marks in column 72. Sample VT AM PU and LU Definitions for DB2 Connect If your security policies allow it, it is recommended that you enable DYNPU and DYNLU in VT AM to allow any PU and LU access through VT AM.
Sample VT AM Log Mode Definition for DB2 Figure 12 on page 44 shows the sample VT AM logon mode table definition for the IBMRDB and SNASVCMG modes. Note that this example specifies a 4K RUSIZE , which may not be suitable for your environment (for example, if you are using Ethernet, which has a maximum Frame Size of 1536 bytes).
Y ou must define the SNASVCMG logon mode when using APPC. Configuring DB2 Universal Database for OS/390 Before you can use DB2 Connect, your DB2 Universal Database for OS/390 Administrator must configure DB2 Universal Database for OS/390 to permit connections from DB2 Connect workstations.
The sections that follow contain examples of commands to update these tables for DB2 Universal Database for OS/390. W ork with your DB2 Administrator to determine the updates requir ed for your DB2 Universal Database for OS/390 system.
The sections that follow contain examples of commands to update these tables. W ork with your DB2 Administrator to determine the options r equir ed for your DB2 for MVS/ESA system. Updating SYSIBM.SYSUSERNAMES If you want to use secondary authorization IDs, you can use the following SQL command to update this table: INSERT INTO SYSIBM.
where: v NYX1 repr esents the PU name of server involved v IBMRDB repr esents the name of VT AM logon mode v 150 repr esents the maximum number of conversations v Y repr esents the number of sessions pr eallocated at startup. This can also be left as N, or blank (the default) for deferred at startup.
Collecting Information Before you can use DB2 Connect over a TCP/IP connection, you must collect information about both the host database server and the DB2 Connect workstation.
Example W orksheet: T able 3. Example Worksheet for Planning TCP/IP Connections to DB2 Universal Database for OS/390 Ref. Description Sample V alue Y our V alue User Information TCP-1 User Name A.
Configuring the TCP/IP Connection Use the manual steps in this section to complete the configuration and make the connection. Complete the W orksheet: Complete a copy of the example worksheet for each TCP/IP host: 1. Fill in the values to be used for the TCP/IP addr ess and hostname of the DB2 Universal Database for OS/390 host (items 8 and 9).
v 1ST_CONN , the first database that a connection is established to will be used as the T ransaction Manager database for transactions. If this option is used, then the first database connected to must be either a DB2 Universal Database V ersion 5 or later database, or a DB2 Universal Database for OS/390 V ersion 5.
CONNECT and BIND: Finally , connect to the target host server and bind the utilities and applications to the server using commands similar to the following in the command line processor: connect to MVSIPDB1 user USERID using PASSWORD bind path/bnd/@ddcsmvs.

Running Java Programs Y ou can develop Java programs to access DB2 databases with the appropriate Java Development Kit (JDK) on AIX, HP-UX, Linux, OS/2, Silicon Graphics IRIX, Solaris, or W indows 32-bit operating systems. The JDK includes Java Database Connectivity (JDBC), a dynamic SQL API for Java.
Configuring the Environment T o build and run DB2 Java programs, you need to install and configur e the appropriate version of the Java Development Kit (JDK) on your development machine: AIX: The Java Development Kit (JDK) V ersion 1.1.2 for AIX from IBM.
Y ou may want to pipe the output to a file for easier viewing. The JDK11_PATH field appears near the beginning of the output. For more information on these commands, refer to the Command Refer ence . On Solaris, some Java V irtual Machine implementations do not work well in programs that run in a ″ setuid ″ envir onment.
java prog_name where prog_name is the name of the pr ogram. The DB2 JDBC driver handles the JDBC API calls from your application and uses the DB2 CAE to communicate the requests to the server and r eceive the results. An SQLJ application must be bound to the database before it is run.
