(1) If multiple database connections are defined in the configuration, then the cache files continue
processing. All data for the failed connection is written to an .sql file.

(2) Data is stored in separate .sql files depending on whether the Real Time option or the Transaction Cache
Files option was used on the Transaction Definition dialog box. This allows you to recover this data.
