AE DB Archive

Archiving

The utility AE DB Archive can be used to remove the increasing amounts of data from the AE databaseA database is an organized collection of data including relevant data structures.. Archived data is still available for years, it is stored in 7 bit ASCII code and can be displayed using theArchive Browser.

Log on to the utility using the client that should be archived. You can also archive the relevant data in batch mode (see Start Parameters). The settings that are specified in the utility apply. End the utility and a dialog displays in which you can store the particular settings.

Database fields that are written to archive files are separated by semicolons. If semicolons are also used in the archive keywords, the separation of database fields is no longer unique. Therefore, the utility AE DB Archive converts the semicolons that are used in archive keywords to commas.

Note that the INI file of the archiving program must also be adjusted.

External report analyses can also be made using the utility AE DB Archive.

After a successful archiving run, the data records are marked with a flag. Before you start to reorganize the data stock, you can specify that only data records should be taken into account that show the archive flag. Use the parameter no_archive_check= for this purpose.

Forecast

A forecast can be created before the actual archiving process starts. The data records that should be archived are counted in according with the specified settings and the results are displayed in tables. If data has already been archived for this client, the estimated amount of data and the estimated duration (hours:minutes:seconds) of the archiving process is forecasted on the basis of this information.

As forecasts are created on the basis of the information that has been accumulated in previous archiving processes, forecasts become more exact with each archiving process and the growing number of data records that has already been archived.
