HPjconfig is a configuration
tool for tuning your HP-UX 11i system to match the characteristics
of your application. It provides kernel parameter recommendations
tailored to your HP-UX hardware platform and application characteristics. HPjconfig has features for saving and restoring configurations
so you can distribute customized recommendations across your customer
base.
HPjconfig can also be used
to verify that your HP-UX system has all the necessary patches required
for Java. The HP-UX patches required for Java can be found at the
following website:
http://h20361.www2.hp.com/en/HPUXJAVAPATCHES/index.html
HPjconfig is a pure Java Application
that runs on the HP-UX SDK or JRE for the Java 2 Platform version
1.4.2.x, 5.0.x, and 6.0.x. HPjconfig is supported
on HP PA-RISC 11i v1 (11.11), 11i v2 (11.23), 11i v3 (11.31), and
HP Itanium® 11i v2 (11.23) and 11i v3 (11.31). All HP-UX 11i
HP Integrity Itanium® and HP-9000 PA-RISC systems are supported.

HPjconfig can be run in either
graphical user interface (GUI) mode or non-GUI (command-line) mode.
In either mode, it generates a summary of the configuration information
in the log file named HPjconfig_<hostname>_<date>_<timestamp>.log. This log file name can be specified using the -logfile option.
Following is the usage information for the HPjconfig command:
usage:
HPjconfig [ options ] -gui
HPjconfig [ options ] <object> <action>
objects: -patches &| -tunables
actions: -listreq | -listmis | -listpres | -apply
options:
-patches operate on java-specific patches
-tunables operate on java-specific tunables
-listreq list all java required patches or tunables that are applicable to this system
-listmis list missing java-specific patches or tunables on the system
-listpres list applied (installed) java-specific patches or tunables on the system
-apply apply (install) missing java-specific patches or tunables on the system
-javavers java versions for selecting patches e.g 1.2, 1.3, 1.4, 5.0
-[no]gui run in GUI mode
-logfile name of log file
-proxyhost HTTP proxy host name for accessing live data
-proxyport HTTP proxy port for accessing live data
-help show help string and exit
-version show version string |
The following examples show how to execute HPjconfig in GUI mode from the csh and
the ksh:
(csh) $ setenv DISPLAY <Display's IP Address>:0.0
$ setenv PATH $PATH:/usr/sbin
$ java -jar HPjconfig.jar
(ksh) $ export DISPLAY=<Display's IP Address>:0.0
$ export PATH=$PATH:/usr/sbin
$ java -jar HPjconfig.jar |
The following four figures
show the System, Application, Patches, and Tunables tabs for the HPjconfig tool:
The following commands show how to execute HPjconfig in non-GUI mode. The -help option
lists options you can use in this mode.
$ cd <hpjconfig_installation_dir>
$ java -jar ./HPjconfig.jar -nogui -help |
The following example executes HPjconfig in non-GUI mode to list missing patches for Java SDK 1.4:
$ java -jar HPjconfig.jar -nogui -patches -listmis -javavers 1.4
