Chapter 1 Installation on a Solaris^TM Platform

The steps for installing and starting the Java Dynamic Management Kit in a Solaris^TM environment are described in these sections:

• "Planning Your Installation"

• "Installing the Software on a Solaris Platform"

• "Setting Environment Variables in a Solaris Environment"

Planning Your Installation

Plan your installation to determine where to install the packages supplied with the product and to ensure that your machine meets the installation requirements.

Upgrading from Previous Versions

If you are upgrading your Java Dynamic Management Kit from versions 3.0 or 3.2, you are not required to uninstall the earlier version. Version 4.0 has different package names and a different installation structure that allows both old and new versions of the product to co-exist on the same machine.

However, if you are reinstalling version 4.0 of the Java Dynamic Management Kit, you should first remove your previous installation. This procedure is described in "Removing or Reinstalling the Java Dynamic Management Kit on a Solaris Platform". Then you may proceed to reinstall the current version.

Software Packages

The Java Dynamic Management Kit 4.0 is composed of the Solaris software packages listed in Table 1-1. It is possible to install only certain packages on a machine, according to your requirements. There is a version of each package for both the Java^TM 2 and the JDK^TM 1.1 environments.

Installation Requirements

Hardware Platforms

The Java Dynamic Management Kit runs on Solaris SPARC^TM and Intel platforms and requires a minimum of 32 Mbytes of RAM.

Software

The Java Dynamic Management Kit requires the following software:

• Solaris 2.6 or Solaris 7 operating environment

• Java^TM 2 SDK or the JDK^TM 1.1.8 (Solaris reference implementations)

Disk Space

The disk space required by the software and documentation packages is as follows:

The installation software will compute the size of the packages you wish to install and warn you if your disk is full.

By default, the packages are installed under the /opt directory. The packages can be relocated if you choose the Custom installation. However, if you want to change the root path of the installation database, you must use the pkgadd -R root_path command. For information about customizing your root path, please refer to the pkgadd(1M) man page.

Installing the Software on a Solaris Platform

These instructions assume that you are already familiar with installing software products on machines running a Solaris operating environment, and that you are installing from a local CD-ROM drive.

The installation process uses the Solaris Web Start Wizards^TM software to simplify and speed up the installation of packages on a Solaris platform. The wizard is a Java class that runs in the Java Runtime Environment, from version 1.1.6 to 1.2.2. Make sure that the java command is in your path before running the installer script.

You must have super-user privileges in order to install the Java Dynamic Management Kit on a Solaris platform.

Installing the Product Software

1. Insert the product CD-ROM into the CD-ROM drive.

   If the Volume Manager (vold) is running on your machine (the default), then the CD-ROM is mounted automatically under /cdrom/jdmk_4_0 when it is loaded in the drive.

   If the Volume Manager (vold) is not running on your machine, create a directory called /cdrom/jdmk_4_0 and mount the CD-ROM manually (you must be root to do this):

   # mkdir -p /cdrom/jdmk_4_0 # mount -rF hsfs CD-RomDeviceName /cdrom/jdmk_4_0

   CD-RomDeviceName is the directory which represents the CD-ROM drive on your machine, for example, /dev/dsk/c0t0d0s0.

2. There is a separate installer script for each version of the Java Development Kit. Type one of the following commands according to the environment in which you will use the Java Dynamic Management Kit:

   JDK 1.1 $ /cdrom/jdmk_4_0/solaris/11/install.sh

   Java 2 $ /cdrom/jdmk_4_0/solaris/12/install.sh

   You may perform both installations if you wish, they are placed in distinct directories.

3. Type the root password for your machine when prompted to do so by the installer:

   Solaris Web Start installer To use this installer you will need to be the system's root user. Please enter this system's root user password Password:

   This will launch the interactive installer window from which you will complete the installation. If you encounter problems while using the installer scripts or running the installation wizard, please see "Alternate Installation Procedures" for a workaround.

4. Follow the instructions of the installation wizard to lead you through the installation.

   If you choose the Typical installation, all of the product packages will be installed in the default location: /opt.

   If you choose the Custom installation, you can select the packages you want to install and specify a different location. Click the "Browse" button and then choose the path of the new installation directory.

   In every case, the installation wizard will automatically create an uninstallation wizard that can remove the exact configuration that was installed. See "Removing or Reinstalling the Java Dynamic Management Kit on a Solaris Platform" for details.

5. Once the installation is finished, you may want to view or copy the documents in the /cdrom/jdmk_4_0/docs directory. See "Printable Documents" for a description of these books. When you are finished, eject the CD-ROM.

   If Volume Manager (vold) is running on your machine, the CD-ROM is unmounted automatically when it is ejected:

   $ eject cdrom

   If Volume Manager (vold) is not running on your machine, unmount the CD-ROM manually before you eject it (you must have super-user privileges to run the umount command):

   # umount /cdrom/jdmk4.0 # eject cdrom # rmdir /cdrom/jdmk4.0

Alternate Installation Procedures

If you cannot launch the installation wizard, you can simply install the software with the Solaris packages in the same directory. Follow this procedure once the CD-ROM is mounted. You must also have super-user privileges to run the pkgadd command.

Installing with pkgadd

1. As root, type the following command to start pkgadd:

   # /usr/sbin/pkgadd -d /cdrom/jdmk_4_0/solaris/JDKversion

2. Type the numbers corresponding to the packages you want to install.

   To install the full Java Dynamic Management Kit, including the documentation, type all to choose all the available packages. The installation program may prompt you with questions about package dependencies and running installation scripts. Type y to answer yes to all questions and complete the installation normally.

3. When the installation is finished, type q to stop pkgadd.

   You can then view the documentation or eject the CD as described in Step 5.

Removing or Reinstalling the Java Dynamic Management Kit on a Solaris Platform

You should remove the existing software packages if you are reinstalling version 4.0 of the Java Dynamic Management Kit. If you installed the packages with the installation wizard, there is a Java class file which you can launch to lead you through the uninstallation procedure.

You must have super-user privileges to remove Solaris packages, so you must be root when launching the uninstallation wizard.

Running the Uninstallation Wizard

1. Go to the location of the installed software and launch the uninstallation wizard class:

   # cd installDir/SUNWjdmk/jdmk4.0/JDKversion # java uninstall_jdmk40_solaris_JDKversion

   You may have to add the current directory (.) to your classpath to run the wizard class.

2. Choose the type of uninstallation you wish to perform and follow the instructions.

   A Full uninstall will remove all of the Java Dynamic Management Kit packages that were installed.

   A Partial uninstall will let you choose the packages you wish to remove. You may launch this wizard again to remove the other packages at a later date.

3. Click the "Details" button on the last screen of the wizard to make sure the uninstallation is complete. When you are done, exit the wizard.

   Upon exiting, the working directory will have been deleted by the uninstallation process. You will have to change to an absolute directory name. For example:

   # cd installDir

If you installed the product packages directly with the pkgadd command, you will have to remove them with the pkgrm command. You must have super-user privileges to remove software packages. If you have a full installation of the Java Dynamic Management Kit type the following to remove all of its packages, replacing x with the Java version number (1 or 2):

#	/usr/sbin/pkgrm SUNWxjdtk SUNWxjdrt SUNWxjdex SUNWxjddc

If your host machine only has certain packages installed, list only these on the pkgrm command line. To find out which Java Dynamic Management Kit packages are already installed on your machine, type:

$ /bin/pkginfo | grep xjd
application SUNWxjddc      Java DMK online documentation
application SUNWxjdex      Java DMK examples
application SUNWxjdrt      Java DMK runtime
application SUNWxjdtk      Java DMK tools

If you are reinstalling the Java Dynamic Management Kit software, you can now follow the steps in "Installing the Product Software".

Setting Environment Variables in a Solaris Environment

PATH, CLASSPATH and LD_LIBRARY_PATH

The CLASSPATH environment variable tells the Java virtual machine where to find the class libraries, such as the jdmktk.jar file.

The PATH environment variable specifies the location of executable files, for example, the proxygen tool and the mibgen compiler.

The LD_LIBRARY_PATH environment variable specifies the location of native libraries, for example, the libstat.so kernel statistics library.

The tools provided in the Java Dynamic Management Kit and the programs that you compile and run rely on the values in these variables. Modify these environment variables according to your Java version, as shown in Table 1-2.
