Usage Documentation
The HP-UX Programmer's Guide for Java 2 on the BSC at http://www.hp.com/go/
hpux-java-docs contains 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.
For more information, refer to Oracle's Java HotSpot VM Options at http://
www.oracle.com/technetwork/java/javase/tech/vmoptions-jsp-140102.html.
Removing support for unwanted architectures in the JRE
Under the RTE license agreement, partners who redistribute the RTE may remove
support for unwanted architectures. Functional components may NOT be removed
under any circumstances. Beginning with the 1.4.2.05 release, you may remove support
for unwanted architectures as follows
The following commands assume that the RTE has been installed in the standard
location, that is, /opt/java1.4/.
The swremove commands must be run as root. Use these command lines:
• or HP Integrity (Itanium) system, to remove PA_RISC 1.1 support
/usr/sbin/swremove Jre14.JRE14-PA11 Jre14.JRE14-PA11-HS
(The -pa11 command line option will no longer work.)
• On a PA-RISC system, to remove 64-bit support:
/usr/sbin/swremove Jre14.JRE14-PA20W Jre14.JRE14-PA20W-HS
(The -d64 command line option will no longer work.)
• On an HP Integrity system, to remove 64-bit support:
/usr/sbin/swremove Jre14.JRE14-IPF64 Jre14.JRE14-IPF64-HS
(The -d64 command line option will no longer work.)
• PA_RISC 2.0 support is not typically installed on HP Integrity, but if it is, to remove
it:
/usr/sbin/swremove Jre14.JRE14-PA20 Jre14.JRE14-PA20-HS \
Jre14.JRE14-PA20W Jre14.JRE14-PA20W-HS
Support for dynamic thread local storage (TLS)
Dynamic thread local storage is fully supported on all HP Integrity (Itanium) systems,
beginning with SDK Versions 1.4.2.00 and 5.0.
