You can run SQL Anywhere in special modes for particular purposes.
Read-only You can run databases in read-only mode by supplying the -r option. You cannot start databases with auditing turned on in read-only mode. See -r server option.
Bulk load This is useful when loading large quantities of data into a database using the Interactive SQL INPUT command. Do not use the -b option if you are using LOAD TABLE to bulk load data.
Starting without a transaction log Use the -f database option for recovery—either to force the database server to start after the transaction log has been lost, or to force the database server to start using a transaction log it would otherwise not find. Note that -f is a database option, not a server option.
Once the recovery is complete, you should stop your server and restart without the -f option.
See -f recovery option.
