B2.2  Program Installation
B
D     If you are using EM/dBS for the first time, read section
D     2.2.1, "First Time Program Installation", before beginning
D     installation. If you are upgrading to a larger equipment
D     record capacity version of EM/dBS, see section 2.2.3, "Upgrade
D     Installation". If you have used EM/dBS before and are
D     installing a newer version, see section 2.2.2, "Update
D     Installation". Network users should also read section 2.2.4,
D     "Network Installation".
D
D     Detailed installation instructions are provided with the
D     EM/dBS floppy disks.
D
D     To use the program after installation follow the
D     instructions in section 2.3, "Starting the EM/dBS Equipment
D     Maintenance System".

B     2.2.1   First Time Program Installation
B
D     This section gives background information for first time
D     users of EM/dBS.
D
C     NOTE: After reading this section, follow the "Program
C     Installation" instructions included with the EM/dBS
C     diskettes to install EM/dBS on your hard disk.
C
D     The EM/dBS system has various types of files provided on the
D     installation disks.   There are files which contain the
D     program itself (with file extensions .EXE, .OVL, and .FRM).
D     All of the program files provided as part of the EM/dBS
D     Equipment Maintenance System will be installed in one hard
D     disk directory, normally named EMS. In addition to the
D     program files, there are data files (with file extensions
D     .DBF, .DBT, and .MEM). The database files will be installed
D     in a subdirectory of the EMS directory, normally called
D     DATA1. After you begin running EM/dBS, index files will be
D     created to help locate information more quickly (these will
D     have extensions .NTX). If your program disks use the
D     "INSTALL" program for installation, the required directories
D     will be created automatically after you are prompted for
D     their names. If your program disks are not in "INSTALL"
D     format, you will need to create the appropriate directories
D     before copying the information to your hard disk.
D
D     If you want to use EM/dBS for more than one separate
D     application (such as to separate the BioMed data from the
D     Engineering data), additional data subdirectories can be
D     created (DATA2, DATA3, etc.) in the EMS directory, and the
D     data files (.DBF, .DBT, and .MEM) installed on each
D     subdirectory. This will enable separate storage and
D     management of data, but will require only one copy of the
D     EM/dBS software (on the EMS directory). If your disks are in
D     the "INSTALL" format, this information can be copied
D     automatically using the "Create Additional Data Directory"
D     option.
D
D     Before installing EM/dBS verify that there is no other
D     directory named EMS on the root directory of that drive of
D     your hard disk.
D
D     Note that the instructions included with your disk will use
D     the C: drive for installation. If you intend to use a
D     different drive designation (e.g., D: or E:) on your hard
D     disk for the EMS directory, substitute that drive letter for
D     C: in the instructions. Entries you will need to make from

D     your keyboard are indicated in bold face type.
D
D     Proper operation of EM/dBS will require that you have a
D     CONFIG.SYS file with the FILES parameter set to at least 20,
D     and the BUFFERS parameter set to at least 8. In addition,
D     any background programs or disk cache systems must be
D     disabled.
D
D     EM/dBS also uses a PATH command to control program
D     execution. The path is set by the EMDBS.BAT file in DATA1
D     when starting the program. After program termination, the
D     user will be returned to the root directory and the original
D     path restored.
D
C     NOTE: The version of EMDBS.BAT that is supplied with the
C     program will create a file called "SAVEPATH.BAT" in your
C     root directory. If you already have a file by that name in
C     the root directory, the EMDBS.BAT file should be modified
C     before you run the program.
C
B     2.2.2   Update Installation
B
D     Updating to a newer version of EM/dBS should be quite easy,
D     but it is very important to read the Update Installation
D     instructions in this section before installing the new
D     software to assure that the data conversion will be
D     completed properly.
D
C     NOTE: Do not begin the installation of any new software
C     disks until the program and data files have been backed up
C     and instructions (1)-(4) in this section completed. Also
C     refer to the instructions included with the update
C     diskettes.
C
D     (1) Archive any work orders that are not needed in active
D          status. The update program will correctly convert all
D          work order data, but the smaller the data files are,
D          the quicker the conversion will be.
D
D     (2) Backup the entire \EMS\ program directory. This backup
D          will contain the older version of your software. If
D          there is any problem during installation, you can
D          always restore the previous version of the program
D          until the installation problem has been solved.

D     (3) Back up the data files on \EMS\DATA1 (and all files that
D          may be in other data subdirectories). This is a very
D          important step. If there are any problems during
D          conversion, the data from this backup can be restored
D          and the conversion process rerun. Without a backup, it
D          could be quite costly to try to recreate lost data.
D
D     (4) Check the available disk space on your hard disk drive.
D          The more disk space that is available, the faster the
D          conversion process will run. If you feel comfortable
D          using DOS commands, you can erase the .NTX files before
D          you begin the conversion (be very careful not to erase
D          any other files).
D
D     (5) Follow the instructions for installing an update,
D          included with your diskettes, to copy the new programs
D          onto your hard disk.
D
D     Any data conversion that may be required when installing
D     your update will be performed automatically the first time
D     you use your new version of EM/dBS. If you have very large
D     databases or a very slow computer, this could take a
D     considerable amount of time. The conversion program will
D     check your available disk space, as each database is
D     converted, to make sure enough space is available.
D
D     If your upgrade installation aborts at any stage during the
D     conversion process, please note any messages displayed, and
D     contact Specific Designs before continuing with the
D     installation.
D
B     2.2.3   Upgrade Installation
B
D     When upgrading to a network version of EM/dBS, or to one
D     with a larger equipment record capacity, it will not be
D     necessary to perform any data conversion unless you are also
D     updating to a newer version of EM/dBS. However, any time you
D     make a change to your software, it is very important to back
D     up your data and current version of the program. If  you are
D     also updating to a newer version of EM/dBS, follow the
D     instructions in section 2.2.2, otherwise:
D
D     (1) Backup the entire \EMS\ program directory. This backup
D          will contain the previous version of your software. If
D          there is any problem during installation, you can
D          always restore the previous version of the program
D          until the installation problem has been solved.

D     (2) Back up the data files on \EMS\DATA1 (and all files that
D          may be in other data subdirectories).
D
D     (3) Follow the instructions for installing an upgrade,
D          included with your diskettes, to copy the new programs
D          onto your hard disk.
D
B     2.2.4   Network Installation
B
D     The network version of EM/dBS can be loaded on your computer
D     and run as a single user system if you do not have your
D     network installed. It will, however, also run from multiple
D     work stations that do have network software in place. EM/dBS
D     should be loaded onto the hard drive of the computer
D     designated as the file server. The EM/dBS system has been
D     successfully installed and run on networks using the ELS
D     Level I, Level II, and the Advanced Netware by Novell using
D     Ethernet, Token Ring, or Arcnet topologies. Other network
D     software and/or topologies may function properly. The EM/dBS
D     software should run on any NETBIOS network operating system.
D
D     The EM/dBS software, version 3.50 has been extensively
D     modified to insure proper network file handling. As with any
D     network system, data records must be locked when they are
D     being updated, and the EM/dBS system assures that the data
D     cannot be modified by another user while it is being edited.
D     Since only one user at a time can edit a data record, it is
D     important for network users to avoid keeping a record in
D     edit mode for an extended period of time.
D
C     NOTE: When you leave your terminal, it is a good idea to
C     make sure a menu is displayed on the screen, then you know
C     that you are not editing a data record.
C
D     Some of the EM/dBS system functions require access to all
D     records in a database. These functions include reindexing
D     databases, opening a new period work order schedule,
D     removing deleted records from the databases, changing key
D     fields, archiving work orders, and opening a new year. While
D     these operations are being performed the entire database
D     will be locked and it will not be available to other users.
D     It is recommended that these functions be performed at times
D     that will not prove inconvenient to a majority of the
D     network EM/dBS users.

D     A message is displayed when a user tries to gain access to a
D     record already being edited by another user.
D
C     NOTE: Data may be lost if you exit during a record locking
C     conflict.
C
D     Generally, if you are in the middle of a complex process, it
D     is best to wait until the record becomes available and
D     update it, rather than quit out when the locked message is
D     displayed. Normally, the record is only locked for a short
D     period of time and the update can be made successfully. If
D     the record remains locked for a long period of time, it may
D     be necessary to check other terminals to determine who has
D     the record locked and when it will be available. If you do
D     exit, temporary files may be left on the system, and a
D     system administrator should remove them when no  EM/dBS
D     users are on the system. Temporary data files will have a
D     file name starting with four or five random numbers in front
D     of the letters "TMP". These files can be deleted from the
D     data subdirectory using the DOS command
D
C               C:\EMS|DATA1> DEL ?????TMP.* <Enter>
C
D     The EMDBS.BAT file included with your network diskettes is
D     standardized for a Novell network. There are several
D     commands in this batch file that may need to be changed to
D     meet the needs of your system.
D
D     *  If you are not running on a Novell network, the CAPTURE
D        command will need to be removed or replaced.
D
D     *  If your COMMAND.COM file is not located in the root
D        directory of your file server, you will need to modify
D        the COMSPEC command in EMDBS.BAT.
D
D     *  The PATH commands may need to be modified to reflect the
D        proper path from your data subdirectory to your program
D        files on the EMS directory (e.g. \PUBLIC\EMS).
D
B2.3  Starting the EM/dBS Equipment Maintenance System
B
D     (1) Type the file name EMDBS to start the program from the
D          \EMS\DATA1 subdirectory. (The active directory must be
D          \EMS\DATA1.)

D     (2) Users that have shell menu screens may establish the DOS

D          may want to make a batch file in the root directory to
D          enable fast entry into the program. The creation of one
D          such batch file program is shown below that will
D          automatically change to the \EMS\DATA1 subdirectory and
D          start the program. When Quitting the EM/dBS program,
D          the original paths set by the AUTOEXEC.BAT file will be
D          reset. You must be in the root directory of the C:
D          drive to create this batch file. (Please refer to your
D          DOS manual for more information about creating batch
D          files.)

C               Z)
C
D     To start the program from the root directory of the C:
D     drive, simply type EMDBS <Enter>.
D
D     The first time you run the program, or after you install an
D     update, the program will create "index files" for all of the
D     databases. These index files are used by the program to find
D     information in the databases, just like a book's index can
D     be used to find the location of information in a book. This
D     process will not be repeated each time you run EM/dBS.
D     Instead, an "EM/dBS" logo will scroll onto your screen (If
D     you wish to skip the logo display, you may hit any key and
D     the logo will stop scrolling). Non network users will be
D     asked to confirm that the system date is correct. If it is,
D     press <Enter>. If the date is incorrect, enter the new date
D     and then press <Enter>. Now the EM/dBS logo will scroll off
D     the screen (if you wish to abort this display, hit any key
D     and the logo will disappear), and the main menu will appear.
D     You are now ready to start using EM/dBS!
