8.5 General Troubleshooting

- Stress test driver settings lost

Stress test profiles were changed or newly created and are no longer there.

Remedy: The file PERM_MEM.DAT in the Windows directory was inadvertently deleted

or overwritten. A backup of this file should be made after changing profiles so that it can

be restored even after a hard disk error (restore file into Windows directory).

- Defective data sets in the database

Errors occur during patient selection, but not when selecting examination options.

Remedy: Contact technical support for a reorganisation tool, which may repair the error

in the data base.

By activating the REORG procedure you can reorganize defective BTRIEVE files from

CardioSoft. This repair procedure may become necessary when the data become

damaged for some reason or another (e.g. after a power failure). To carry out the repair

procedure successfully, CardioSys must first of all be terminated. There must be

sufficent memory space on your hard disk.

As a general rule, the following applies:

memory space required = twice as much free memory space as the sum of all

The original CardioSys files are still available in the form of “OLD” files after

reorganization and should only be deleted when the reorganization has been completed

successfully.

If the reorganization is unsuccessful, the only option remaining is to retrieve the latest

backup data.
