Pervasive PSQL Event Logging
Chapter contents
All Pervasive PSQL components write status and error messages to the same log file. If two or more Pervasive-based applications are running on the same machine, they share a single event log.
The event log is called PVSW.LOG on Windows platforms and event.log on Linux platforms. )
