Chapter 9. Migrating From The Jdbc/Sqlj Driver For Os/390 And Z/Os To The Ibm Data Server Driver For Jdbc And Sqlj - IBM DB2 Manual

Chapter 9. Migrating from the JDBC/SQLJ Driver for OS/390
and z/OS to the IBM Data Server Driver for JDBC and SQLJ
You need to migrate to the IBM Data Server Driver for JDBC and SQLJ before you
migrate to DB2 Version 9.1 for z/OS.
Prerequisites for migrating to the IBM Data Server Driver for JDBC and SQLJ:
v Java 2 Technology Edition, V1.4.2 service release 2 (SR2), or later.
v TCP/IP
v DB2 for z/OS distributed data facility (DDF) and TCP/IP support.
v Unicode support for OS/390 and z/OS servers.
v Latest IBM Data Server Driver for JDBC and SQLJ maintenance
Important: The JDBC/SQLJ Driver for OS/390 and z/OS is no longer supported.
This information is provided only to help you diagnose problems in your
applications after migration to the IBM Data Server Driver for JDBC and SQLJ.
To migrate to the IBM Data Server Driver for JDBC and SQLJ, follow these steps:

The following functions require Java 2 Technology Edition, V5 or later.
– Accessing DB2 tables that include DECFLOAT columns
– Using Java support for XML schema registration and removal
JDBC 4.0 functions require Java 2 Technology Edition, V6 or later.
The IBM Data Server Driver for JDBC and SQLJ supports 31-bit or 64-bit Java
applications. If your applications require a 64-bit JVM, you need to install the
IBM 64-bit SDK for z/OS, Java 2 Technology Edition, V5 or later.
TCP/IP is required on the client and all database servers to which you connect.
If any Java programs will use IBM Data Server Driver for JDBC and SQLJ type 4
connectivity to connect to a DB2 for z/OS Version 7 server, the OS/390 or z/OS
operating system must support the Unicode UTF-8 encoding scheme. This
support requires OS/390 Version 2 Release 9 with APAR OW44581, or a later
release of OS/390 or z/OS, plus the OS/390 R8/R9/R10 Support for Unicode.
Information APARs II13048 and II13049 contain additional information.
Refer to DB2 Program Directory to ensure that you have the latest maintenance
installed for FMID JDB9912.
1. Back up all of the .sqlj, .ser, .java, .and .class files, packages, and DBRMs for
applications that you created under the JDBC/SQLJ Driver for OS/390 and
z/OS.
2. On DB2 for z/OS, set subsystem parameter DESCSTAT to YES. DESCSTAT
corresponds to installation field DESCRIBE FOR STATIC on panel DSNTIPF.
This step is necessary for SQLJ support.
3. In z/OS UNIX System Services, edit your .profile file to customize the
environment variable settings. You use this step to set the libraries, paths, and
files that the IBM Data Server Driver for JDBC and SQLJ uses.
4. Convert JDBC/SQLJ Driver for OS/390 and z/OS properties to IBM Data
Server Driver for JDBC and SQLJ properties.
5. Optional: Customize the IBM Data Server Driver for JDBC and SQLJ
configuration properties.
