HP-UX 11i Java™ JDK/JRE Version 7.0.09 Release Notes
Removing support for unwanted architectures in the JRE
Under the JRE license agreement, partners who redistribute the JRE may remove support
for unwanted architectures. Functional components may NOT be removed under any
circumstances. You may remove support for unwanted architectures as explained below.
The following command assumes that the JRE has been installed in the standard location,
/opt/java7/.
To remove 64-bit support:
/usr/sbin/swremove Java70.Jre70.JRE70-IPF64 Java70.Jre70.JRE70-IPF64-HS
Usage documentation
In addition to any usage documentation described in this section, see the HP-UX
Programmer's Guide for Java 2 under “User guide” at http://www.hp.com/go/
hpux-java-docs for usage documentation for developers. There you will find information
on HotSpot options, HP-specific options and features, suggestions and examples for
allocating memory, how to use WDB to examine backtraces in Java threads, code
examples for using Java Native Interface, and more. You might find the JDK/JRE 6.0.n
and 7.0.n Usage Notes appendix especially useful.
X/Open Socket Support
Starting in JDK/JRE 7.0.05, support for X/Open sockets has been added. This corrects
the behavior of the java.net.Socket.setSoLinger() method. Java native methods
outside the JDK that call socket functions are not affected.
To enable this support, use the option:
-XX:+UseXOpenSockets
You must also have the following X/motif patch installed on your system:
• PHSS_43341 (11.23)
• PHSS_43291 (11.31)
Handling large GC log files
In JDK/JRE 7.0.01 new Oracle command line options were introduced to support GC
log file rotation. These options are
-XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=<num_of_files>
-XX:GCLogFileSize=<logsize>
Prior to JDK/JRE 7.0.04, this option could be used with-Xloggc, but was not supported
with -Xverbosegc. Starting in JDK/JRE 7.0.04, this option is also supported with
-Xverbosegc.
HP's GC log rotation option,-XX:GCLogLimits, introduced in JDK/JRE 6.0.05, remains
unchanged and is still supported with both-Xloggc and–Xverbosegc. However, in
the JDK/JRE 7.0.01 through JDK/JRE 7.0.03 releases, when-Xloggc was specified in
