The following is the latest on content, availability and service levels:
This product is the z/OS 31-bit Java product that supplies the Java SDK 6 APIs.
It became generally available in December, 2007 and is
periodically updated with cumulative service and improvements.
The IBM 31-bit SDK for z/OS, Java Technology Edition, V6 requires either:
- z/OS Version 1 Release 7 or higher
The IBM 31-bit SDK for z/OS, Java Technology Edition, Version 6 will be serviced through
at least September, 2011.
For more product details, read the
formal announcement.
Compatibility:
IBM 31-bit SDK for z/OS, Java Technology Edition, V6 (5655-R31) has the same functions
as IBM SDK for z/OS, Java 2 Technology Edition (5655-N98), V5.
31-bit SDK for z/OS, Java Technology Edition, V6 (5655-R31) and SDK for z/OS, Java 2
Technology Edition, V1.4 (5655-I56), 64-bit SDK for z/OS, Java 2 Technology Edition, V1.4
(5655-M30), 31-bit SDK for z/OS, Java 2 Technology Edition, V5 (5655-N98)
and 31-bit SDK for z/OS, Java Technology Edition, V6 (5655-R32)
are independent products and can co-exist on the same z/OS system.
Most Java applications executed on IBM 31-bit SDK for z/OS,
Java Technology Edition, V5 (5655-N98)
are expected to run unchanged on 31-bit SDK for z/OS, Java Technology Edition, V6,
provided that they did not use deprecated Java 2 SDK 5 APIs.
Additionally, in some cases, because of a small number
of incompatibilities introduced industry wide between Java 2
SDK 5 and SDK 6 APIs, some applications may have to change.
Details on these incompatibilities are available at the
Sun web site.
IBMJSSE2 is the sole JSSE security provider. If the provider list includes references
to the older IBMJSSE, the IBMJSSE2 introduced in the SDK 1.4.2 products will be invoked.
Note that the deprecated com.ibm.net.ssl.* apis will NOT be supported. Use of the
deprecated APIs will require code modifications to use APIs supported by the IBMJSSE2
provider.
Product Content
The IBM 31-bit SDK for z/OS, V6 provides a full function SDK compliant with the
SDK 6 APIs.
Documentation is available for content that is additional to the base.
All content above is shipped with the z/OS SDK product and is zAAP eligible.
If you are migrating from Java 2 Technology Edition, SDK5,
to IBM SDK for z/OS, see:

Getting the Product
Note: The SUN SDK level is SDK 6.
Before installing the code be sure to check the following links:
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.

the non-SMP/E format of the code.
The SMP/E installable format of the code is available only through ServerPac or CBPDO
Order IBM SDK for z/OS through a z/OS ServerPac or CBPDO, which can be ordered
through the Internet (where available) or through the traditional ordering process.
When ordering:
- The product number is 5655-R31
- The subscription and service number is 5655-I48
ShopzSeries provides an easy way to plan and order your
z/OS ServerPac or CBPDO. It will analyze your current
installation, determine the correct product migration, and present your new configuration
based on z/OS. Additional products can also be added to your order (including determination
of whether all product requisites are satisfied).
ShopzSeries is available in the U.S. and several countries in Europe.
In countries where ShopzSeries is not available yet, contact your IBM representative
(or Business Partner) to handle your order via the traditional IBM ordering process.

Who Should Use this SDK6 Product
IBM 31-bit SDK for z/OS, Java Technology Edition, V6 (5655-R31) will be attractive
primarily to customers and ISVs whose Java applications are not constrained by
31-bit addressing and who wish to use Java SDK6. In contrast, Java applications that are storage
constrained by 31-bit addressing should be able to execute in a 64-bit environment
provided by the 64-bit product, IBM 64-bit SDK for z/OS, Java Technology Edition, V6
(5655-R32).
The two products are complementary, have the same SDK6 APIs, and can
be installed and run at the same time. The 64-bit product is not a
replacement for the 31-bit product.
What are the main reasons for staying with the 31-bit product
(or keeping it when you add the 64-bit product)?
- you are not storage constrained by 31-bit addressing.
- your ISV or other middleware requires the 31-bit product.
- your customers are comfortable using the existing SDK5 product.
What are the main reasons for going to the 64-bit product?
- your applications are storage constrained by 31-bit addressing.
- your ISV or other middleware requires the 64-bit Java product.
While the 64-bit product does well in our internal tests, in general, people don't
go to a 64-bit version of a product to improve performance. In fact, a Java
application that runs without storage constraint with 31-bit addressing would
(normally) be expected to run slower with 64-bit.
