  Data Explorer is comprised of five subsystems as follows:

  Base executables | contains all files needed to run Data Explorer.
  Development environment | contains libraries, header files and other tools needed to build a custom executive.
  Samples | example programs, scripts, tutorial, and makefiles.
  Online help and HTML | online help available from the Data Explorer User Interface, and documentation in HTML format.
  PostScript and ASCII documentation | Documentation in PostScript format and for printing and in flat ASCII format for basic minimal viewing.

  All subsystems are placed under a common directory (e.g. `/usr/local/dx`) which is referred to as the root of the Data Explorer installation tree. Architecture-specific executable and library files are placed in the directories `bin_ARCH` and `lib_ARCH` under the Data Explorer root, where ARCH is one of the supported architectures (alphax, aviion, hp700, ibm6000, sgi, solaris, sun4). As part of configuring Data Explorer, links and small files are placed in the public file system that reference files within the Data Explorer root directory. The default Data Explorer root directory is `/usr/local/dx`. In a networked environment, it is most convenient for users if all workstations have Data Explorer available through the same root directory. This makes it easier to run the User Interface on one machine and the server on another.

  Data Explorer is a licensed software product and uses the NetLS licensing system to manage its licensing. Two types of licenses are supported: node-locked and floating (or concurrent-use). Node-locked licenses require a single configuration file containing an enabling password, while the floating license requires that a NetLS license server configured with at least one Data Explorer license is running somewhere within your network. If you expect to use a floating license and you do not have a NetLS license server running in your network you will need to install one (see Chapter 15. "Installing a NetLS License Server"). Please note that node-locked licenses do not require the use or installation of a NetLS license server.

  ## 10.1 Installing on an SGI Workstation from Tape

  Note: The block size of the tape device must be set to 512 bytes. Use the following command to determine the current block size:

      mt -t <device> blksize

  <device> is the appropriate tape device for the operating system from which you run installdx. Example IRIX tape devices are:

      /dev/rmt/tps0d4ns, /dev/rmt/tps0d5ns, ...

  On IRIX be sure to use the no-swap tape drives which have the characters "ns" in the device name.

  Use the following command to set the correct block size if necessary:

      mt -t <device> setblksz 512

  Tape distributions of Data Explorer contain three tar format files. The first contains two install scripts (installdx, install_lsk) and a PostScript file documenting Network Computing System (NCS) issues (ncs_ps.Z). The second contains the Data Explorer installation tree which contains Data Explorer for each of the supported architectures. The third file contains NetLS license server installation kits for each supported architecture. The NetLS license server is used to support the standard licensing mechanism for Data Explorer.

  To install Data Explorer, log in as root, insert the tape in the drive, and type:

      cd /tmp
      tar xvf <device> installdx
      ./installdx <platform>

  <device> is the appropriate tape device for the operating system from which you run installdx. Example tape devices for IRIX are:

      /dev/rmt/tps0d4ns, /dev/rmt/tps0d5ns, ...

  <platform> is used to indicate the platform for which the Data Explorer files will be extracted. The supported platforms are:

      alphax, aviion, hp700, ibm6000, sgi, solaris, sun4

  This argument is optional and the default is the host platform (sgi).

  The installation script will ask if you want to install or deinstall Data Explorer and then a series of questions related to the installation. You will be given the opportunity to set the installation directory and to select the Data Explorer subsystems to install.

  When doing an installation for an architecture other than the current host, you may need to run the Configure script provided with Data Explorer on the workstations to which you expect to export the Data Explorer installation tree. See Chapter 13. "The Configure Script".

  Please follow the instructions presented by installdx carefully. In particular, when asked to give the name of the tape device, be sure to give the name of the non-autorewinding tape drive, examples of which are provided by the script. Also, if at anytime during the tape installation you are asked to mount the next tape, just press the <ENTER> key to have the installation continue normally.

  After installation and configuration is complete, which may take as much as 30 minutes, you will be provided with a unique workstation (node) identifier that must be provided to IBM to acquire the enabling license information. See 10.3 , "Configuring a Data Explorer License for an SGI Workstation" for information on how to reacquire the identifier (if you lose it) and on how to use the node identifier to enable Data Explorer.
