B                          SYSTEM ERRORS
B
B10.1 System Errors
B
D     Run time errors may occur in the user environment, even
D     though the EM/dBS Equipment Maintenance System has been
D     extensively tested before release.
D
D     Several types of errors can occur.
D
D                    (1) Environmental Errors. (DOS System Errors)
D
D                    (2) Errors resulting from corruption of the
D                    databases.
D
D                    (3) Errors existing in the programming
D                    algorithms.
D
B     10.1.1  Environmental Errors
B
D     Environmental errors are caused by improper systems
D     operations, such as an improper path to the program files,
D     running the program from the wrong directory, or improper
D     run time environment. If the printer is turned off, not on
D     line, paper jammed, or out of paper, errors will occur.
D     Copying files to an unformatted diskette, or to a diskette
D     which is full, will also cause environmental errors. If you
D     are using other programs, such as SideKick, in background
D     mode, you may not have enough memory to run all or part of
D     the EM/dBS program. Disk CACHE systems cannot be active for
D     proper operation of EM/dBS.
D
D     If the EM/dBS program does not run at all, check your
D     EMDBS.BAT file for proper configuration. You must start the
D     program using the EMDBS.BAT file, rather than using the
D     EMS.EXE file, in order to set up the correct run time
D     environment. You must also begin program execution in the
D     data directory (usually \EMS\DATA1). If you run the program
D     from the program directory (\EMS\), it will not be able to
D     find your data.
D
D     Environmental errors occurring within the EM/dBS program
D     will display a DOS error message on the top of the screen
D     and a black and white window will pop up to explain the
D     problem. If the problem can be corrected (for example, by
D     turning the printer on), you will be asked if you wish to
D     continue. You may then correct the problem, enter "Y", and
D     continue.

H
H
H
D     If program operation cannot be continued, you will be
D     informed of this and you should press <Enter> to exit
D     EM/dBS. If you understand the problem (for example, the disk
D     is full) you can correct the problem and restart EM/dBS. If
D     you do not understand what caused the problem, you can try
D     the same steps again to verify that the problem can be
D     repeated. If you continue to have trouble you should report
D     the problem to your EM/dBS representative (see section 10.2).
D
D     Run time errors may be a result of the following
D     installation errors:
D
D     (a) Missing or improper CONFIG.SYS file. The minimum files
D          and buffers should be set as follows:
D
C               FILES=20
C
C               BUFFERS=8
C
D     (b) Incorrect PATH designator or default directory when
D          entering the program.
D
C               PATH=\EMS (Path as set by the EMDBS.BAT
C               file)
C
C               \EMS\DATA1> (Default Directory)
C
D     (c) Active resident programs which utilize Random Access
D     Memory (RAM) such as SideKick and print buffers. The EM/dBS
D     Equipment Maintenance System requires 640 Kb for 100 percent
D     error free run time operation. If you utilize other RAM
D     resident programs during EM/dBS operation and run time
D     errors occur, remove the RAM resident programs and reboot
D     the EM/dBS System and see if this corrects the error.
D
D     The following errors may indicate problems with your system
D     configuration:
D
D                    RUN error (not enough memory to run program)
D
D                    Open error (FILES parameter not large enough,
D                    or, file cannot be found because it is
D                    missing or the PATH to the directory is not
D                    correct)

D
D
B     10.1.2  Database Errors
B
D     Database errors can be a result of improperly Quitting the
D     program. You should always quit the EM/dBS Equipment
D     Maintenance program by selecting the "Q" (Quit) menu
D     selection from the main menu display, followed by "Y" (Yes)
D     to exit to DOS.
D
C     NOTE: CAUTION: Never turn off the computer while the system
C     is attempting an operation. Improper quitting can corrupt
C     your database and render it useless. Backup databases on a
C     regular basis to prevent this type of catastrophic loss.
C
D     Daily backup is recommended. It is only a matter of time
D     before all computer users experience a damaged data file or
D     lose an entire hard disk drive. Do not be one of the many
D     who failed to make regular backups of their data. You will
D     not regret the minimum of effort this involves.
D
D     These run time errors may be the result of a corrupted
D     database or from a program error existing in your EM/dBS
D     Equipment Maintenance System. When these errors occur, your
D     best solution is to first quit, then reboot the program and
D     try the same operation again. If the problem persists,
D     reindex the databases (Support Data Main Menu - Utility Menu
D     - "Sort Data (Rebuild Indexes)" option). If the error is
D     consistent and occurs each time you attempt a sequence of
D     inputs, you may have found a program error.

D     The following error messages may indicate a database

D
D                    Undefined Identifier (old or missing database
D                    or memory file, improper data conversion with

B     10.1.3  Program Algorithm Errors
B
D     Extensive efforts have been made to test the EM/dBS software
D     before its release. However, the following errors may
D     indicate a problem with the EM/dBS software.
D
D                    Database required
D
D                    Lock required
D
D                    Exclusive required
D
D                    Field numeric overflow
D
D                    Type mismatch
D
D                    Subscript range
D
D                    Zero divide
D
D                    Expression error
D
D                    Not an array
D
D
D     Normally, you will not be able to continue when this type of
D     error occurs, and your EM/dBS representative should be
D     contacted immediately.

B10.2 Reporting Errors
B
D     All errors should be noted in detail for your Specific
D     Designs Software Systems Support representative. One way to
D     document the error is to press the <PrintScreen> key to
D     print the error screen. Additionally you should print the
D     ERROR.LOG file. This is a record of all of the errors that
D     you have had, and is a valuable tool to help diagnose the
D     problem. From your \EMS\DATA1 DOS prompt type
D
C               C:\EMS\DATA1>TYPE ERROR.LOG <Enter>
C
C               C:\EMS\DATA1><PrintScreen>
C
D     This should print the last few errors that have occurred
D     while using EM/dBS.
D
D     This information can be mailed or delivered to your EM/dBS
D     representative along with a detailed explanation of the
D     sequence of steps taken immediately prior to the occurrence
D     of the error.
D
D     Specific Designs wants to insure a trouble free EM/dBS
D     Equipment Maintenance System and will continue to improve
D     and enhance the system. The company is very receptive to
D     requests, for improvement and changes, to help the program
D     better meet your needs.
