Database Problems

Errors can be caused by inconsistent, invalid, or missing data and/or

index files. An error message will indicate if this occurs.
One source of problems with the data and index files is changes

made outside the AutoMax Programming Executive software. These

changes can be made with DOS (e.g., renaming or deleting files) or

using a dBASE (or compatible) software package to write to the file. If

any of these changes were made, verify that the changes were made

correctly and that the index files are current.
Recovering the data and index files from a valid backup copy should

correct the problem. In addition, it is possible to repair data and index

files using a dBASE (or compatible) software package. However, this

requires an understanding of dBASE and of the databases used in

the AutoMax package. See section 4.19 and Appendix F for

information on the AutoMax database organization.
If the application task files for a rack are deleted or become

corrupted, you may be able to recover them by saving them from the

Processor back to your personal computer. The procedure that

follows can recover only the reconstructible application tasks.
Step 1.

From the System Configurator, create a temporary rack

(e.g., TEMP) in the desired system and section by using

the Add command from the Rack menu (See section

5.1.3).

Step 2.

Access the Task Manager and go online by selecting the

On Line command (See section 8.17).

Step 3.

Enter S" (Save) at the Transfer menu to bring up a list of

all the tasks in the rack. Write down the task names. You

will need these names later in order to recover the utility

tasks (See section 14.4).

Step 4.

Enter the name of the rack configuration object file

(_CONF.CNF) and use the /All option to save all the tasks

in the rack to TEMP (See section 14.4). Then press F3 to

exit the On Line menu and return to the Task Manager.

Step 5.

Access the System Configurator. Use the Import command

from the Rack menu to import the tasks in TEMP to the

new rack. Enter the appropriate Disk:\library\system\TEMP

in the Source Directory for Imported Rack dialog box (See

section 5.3.8).

Step 6.

Access the Task Manager. Select Add from the Task menu

and use the New option to copy the utility tasks to the task

list (See section 8.1.1). All of the application tasks should

now be listed for the rack.

Step 7.

Select Generate Configuration from the Commands menu

to reĆcreate the configuration object file for the rack (See

section 8.16.3).

Step 8.

Return to the System Configurator and use the Remove

command from the Rack menu to delete the temporary

rack (See section 5.3.3).
