Hi,
when I run dblog I got info:
C:\Users\ADMIN>dblog C:\baza\baza1.db
SQL Anywhere Transaction Log Utility Version 12.0.1.3994
"C:\baza\baza1.db" is using log file "baza1.log"
Does it mean log is in the same directory as db? So: "C:\baza\baza1.log"
I managed to recover db using:
1. point the database to a transaction log file that doesn't exist on the file system using dblog (or move the current transaction log to another location)
2. "dbsrv12 baza1.db -f" to recover the database without the transaction log.
Thank you!
I remember I tried to use dbsrv12 -f before but did not point to non-existing log first and computer kept annoying me that baza1.log is invalid log file 
Are there any tools to help find out what was the reason for db failure?
Regards,
Andrzej
