Note: IBM 64-bit SDK for z/OS, Java 2 Technology Edition, V1.4.2 (5655-M30) is now out of service as of September 30, 2008. The product information will move to archive by year end. For more information, see product support.

There is now a later and better z/OS Java 64-bit product; if you are considering a 64-bit SDK product we strongly recommend IBM 64-bit SDK for z/OS Java 2 Technology Edition, V5.

The IBM 64-Bit SDK for z/OS, Java 2 Technology Edition, V1.4 requires either:

• z/OS Version 1 Release 6 or higher
• z/OS.e Version 1 Release 6 or higher

For more product details, read the formal announcement.

Compatibility:
IBM 64-Bit SDK for z/OS, Java 2 Technology Edition, V1.4 (5655-M30) has the same functions as IBM SDK for z/OS, Java 2 Technology Edition (5655-I56), V1.4 with the exception of:

• Persistent reusable function
• Sharing class objects between Java virtual machine (JVM) processes running in the same address space

64-Bit SDK for z/OS, Java 2 Technology Edition, V1.4 (5655-M30) and SDK for z/OS, Java 2 Technology Edition, V1.4 (5655-I56) are independent products and can co-exist on the same z/OS system.

Most Java applications executed on Java for OS/390 (5655-D35) should run on IBM 64-Bit SDK for z/OS, Java 2 Technology Edition, V1.4 unchanged provided they do not use deprecated Java 2 SDK 1.3 APIs. Additionally, in some cases because of some small number of incompatibilities introduced industry-wide between Java 2 SDK 1.3 and SDK 1.4 APIs, some applications may have to change. Details on these incompatibilities are available at the Sun web site.

IBM 64-Bit SDK for z/OS, Java 2 Technology Edition, V1.4 takes advantage of enhanced z/OS linkage capabilities (XPLINK.) The z/OS operating system provides an XPLINK runtime environment for all 64-bit programs, including the JVM. This contrasts with the 31-bit Java product, IBM SDK for z/OS, Java 2 Technology Edition, V1.4 (5655-I56), where it is necessary to ensure that an XPLINK environment is in place when the JVM is launched.

Programs interacting with the 64-bit Java product, whether launching the JVM or being called from the JVM through the JNI interface, must be 64-bit programs. Programs dependent on JNI interfaces may require changes at the interface boundary to conform to 64-bit data types. Application JNI routines written in C will need to be recompiled for 64-bit, which may require some code changes.

Getting the Product

Note: The SUN SDK level is SDK 1.4.2. SUN SDK levels corresponding to previous PTFs, including availability from this website, are in the service summary.  This product is out of marketing and out of service, but a link to the "as-is" non-SMP/E code will be kept temporarily.

Before installing the code be sure to check the following links:

• Prerequisites- Java will NOT function without these APARs.
• Restrictions and other considerations

The non-SMP/E installable format of the code is available only from the web.
Be sure to read additional install information prior to download and install. Check here also after you download and install the code to verify the install.

Download the non-SMP/E format of the code.
