If you experience this error, take the following action:1. Pass the full path to your Progress database in your DSN's. For example:/usr/progress/dbs/demo.db 2. If you use tableview, remove your .pf file from the DSN. Pass the full path to the database in your DSN's database name field. Likewise, pass the -SHN sockets parameters, if required. For example: Lite - Database Options: -db /usr/progress/dbs/demo.db -S pro82a -N tcp -H saturnusMulti-Tier -Database Name: : -db /usr/progress/dbs/demo.db Server: -S pro82a -N tcp -H saturnus 3. Do not pass usernames in your DSN's. "Unknown" errors may arise, if you use authentication parameters which are not defined in the Progress _User table.
