Hi Mark,
Thanks for your answer. It helps me because i'm afraid if I just deleted the log it's going crash. but its automatically create the new one.
1st thing I do is turn off the SQL Anywhere service and automatically SIA is off.
2nd i copied the .log to another path
3rd I install sql anywhere 12 for client
4th I change the destination log to another drive with sybase central (sql anywhere 12 for client)
5th I deleted the log which automatically create in drive C:
6th I started the SQL anywhere for BI and started SIA
7th it's going so well and my drive C: not full anymore even it's gonna impact my another drive
Thanks all for your help
Regards,
Maria
