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.

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)

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.

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 Type mismatch
D
D Subscript range
D
D Zero divide

D Not an array

D
D Normally, you will not be able to continue when this type of

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.
