Scope:
The JAVA version 7.0.0 product also known as 31BIT SDK FOR Z/OS JAVA version 7.0.0 will have maintenance applied to it on June 9th that may have potential impact to users of this version of JAVA on DYIPC1D. Testing is available prior to maintenance being applied to the production environment. See details section below for more information.
Effective Date:
06/09/2013
Group Name:
Users of JAVA version 7.0.0 on DYIPC1D.
Affected Locations:
DYIPC1D only.
Justification:
Notify users of 31BIT SDK FOR Z/OS JAVA version 7.0.0 on DYIPC1D of potential impact of planned maintenance.
Benefits to Users:
Maintenance includes corrections to known security vulnerabilities with JAVA.
Details:
Apply maintenance to 31BIT SDK FOR Z/OS JAVA 7.0.0 that may have potential impact to users of this version of JAVA.
From service refresh 4 onwards, the SDK uses the Oracle
implementation of the java.util.* package, including all classes
within the package. Earlier Refreshes of the SDK used customized
versions of the Harmony class libraries. This change establishes a
common implementation point for the java.util.* package, enabling
consistent performance and behavior characteristics across Java
implementations. In general, this change provides better
performance compared to earlier implementation. However, it is
recommended that sufficient application testing be performed prior
to migrating to service refresh 4, to ensure no negative impact.
DYIPC1D has three different versions of Java installed on it. Those being version 5.0.0, version 6.0.1, and version 7.0.0. This maintenance is for version 7.0.0 only. There are no impacts to the other two versions of JAVA on the DYIPC1D system.
To test this maintenance prior to it being the default for version 7.0.0 point your java activity to mount point: /usr/lpp/java1/
This mount point is to be used for testing only.
