Itanium 1.6.0_12 is a port of JDK 6 update 12 to the Itanium (64 bit) architecture platform.
The full internal version number for this update release is 1.6.0_12-b0404 (where "b" means "build"). The external version number is 6u12. Included in JDK 6u12 for Itanium (64 bit architecture) platform is version 14.0 of the Java HotSpot Server Virtual Machine.
The following JDK, JRE tools are not included in Itanium JDK, JRE 6u12 release:
Please refer to JDK tools and Utilities for JDK tools description.
Only offline installation is available for JDK, JRE 6u12.
The Serviceability Agent is included in Linux distributions of JDK 6u12 for Itanium only.
Tools based on read-only subset of JDI API should work with Serviceability Agent on Linux Itanium. The JDK includes a set of such tools: jdb, jinfo, jmap, jstack.
See known Serviceability Agent issues and limitations section for known bugs in the Seviceability Agent and possible workarounds.
See also Serviceability components description provided by OpenJDK Serviceability Group.
Itanium 1.6.0_12 contains a number of new features that have resulted in significant performance improvements:
-XX:+AggressiveOpts -XX:+AggressiveHeap -XX:ParallelGCThreads=2 -XX:MaxInlineSize=75 -XX:FreqInlineSize=700 -XX:InterpreterProfilePercentage=10 -XX:CompileThreshold=20000 -XX:OnStackReplacePercentage=80 -XX:ReservedCodeCacheSize=128m -XX:PermSize=256m -XX:MaxPermSize=256m -XX:AllocatePrefetchStepSize=128 -XX:AllocatePrefetchStyle=2 -XX:AllocatePrefetchDistance=896 -XX:BiasedLockingStartupDelay=500 -Xmx, -Xms, -Xmn should have sufficiently large values. (For example, -Xms6600m -Xmn5000m -Xmx6600m or -Xms20000m -Xmn18000m -Xmx20000m.)

The installation procedure installs the JDK or JRE 6u12 but not the Java Plugin or Java Web Start (which are not available for 64-bit Windows) or public Java Runtime Environment (when JDK is installed).
To install, download jdk-6u12-windows-ia64.exe or jre-6u12-windows-ia64.exe file and then follow the 32-bit Windows JDK installation or 32-bit Windows JRE installation "Windows Offline Installation" instructions.
Note: If you have jdk/jre-6u12-ea-windows-ia64.exe installed on your computer please uninstall it before jdk/jre-6u12-windows-ia64.exe installation to avoid conflict.
The installation procedure installs the JRE or JDK 6u12 but not the Java Plugin or Java Web Start (which are not available for 64-bit Linux) or the public Java Runtime Environment (when JDK is installed).
The JDK, JRE for Linux 64-bit comes bundled in two install formats - Linux self-extracting files jdk-6u12-linux-ia64.bin, jre-6u12-linux-ia64.bin and Linux RPM in self-extracting files jdk-6u12-linux-ia64-rpm.bin, jre-6u12-linux-ia64-rpm.bin.
To install, download necessary file and then follow the 32-bit Linux JDK installation or 32-bit Linux JRE installation instructions.
Note: If you have jdk/jre-6u12-ea-linux-ia64-rpm.bin installed on your computer please uninstall it before jdk/jre-6u12-linux-ia64-rpm.bin installation to avoid conflict.

The bundles install successfully. Message printing can be disabled by command 'prctl --unaligned=silent'.
The message is a warning for the user that application (dmidecode) works inefficient from performance perspective. The issue is resolved in dmidecode 2.7.
For example, JDK (JRE) 6u11 can not be installed using jdk(jre)-6u11-linux-ia64-rpm.bin file if, on the same machine, JDK (JRE) 6u12 was previously installed using jdk(jre)-6u12-linux-ia64-rpm.bin.

After installation of Itanium JDK (or JRE) 6u12, "JavaHome" contains the path to the last installed JDK (or JRE) instead of the path to the JDK (or JRE) of the highest installed version. After un-installation the value is removed.
The workaround is to put the correct value to the Windows registry manually. See Deploying the JRE on Windows for more details about registry values.
Error 1334.The file 'javaw.exe' cannot be installed because the file cannot be found in cabinet file 'Data1.cab'. This could indicate a network error, an error reading from the CD-ROM, or a problem with this package
Internal Error 2356. Data1.cab
The second case can block installation/uninstallation, as the installer reports that there is a suspended installation process. A reboot of the system helps. After reboot, please, uninstall the previously installed JDK/JRE. Confirm the message, if it appears:
Error 1704.An installation for Java(TM) SE Runtime Environment 6 Update 12 is currently suspended. You must undo the changes made by that installation to continue. Do you want to undo those changes?
This is a known bug in kernels of version less than 2.6.22. Processors older than Montecito (e.g. Madison, McKinley) are not affected.
RHEL4 (Nahant Update 5), kernel 2.6.9-55.EL has this bug. In RHEL5.2(Tikanga), kernel 2.6.18-92.el5 the bug is fixed.
