SQL Anywhere client logs

When you create MobiLink applications with SQL Anywhere remote databases, there are two types of client log file that you should be aware of:

dbmlsync message log
SQL Anywhere transaction log

dbmlsync message log

By default, dbmlsync messages are sent to the dbmlsync messages window. In addition, you can send the output to a message log file using the -o or -ot options. The following partial command line sends output to a log file named dbmlsync.dbs.

dbmlsync -o dbmlsync.dbs ...

Logging dbmlsync activity is particularly useful during the development process and when troubleshooting.

You can control the size of log files, and specify what you want done when a file reaches its maximum size:

Use the -o option to specify a log file and append output to it.
Use the -ot option to specify a log file, but delete the contents the file before appending output to it.
In addition to -o or -ot, use the -os option to specify the size at which the log file is renamed and a new file is started with the original name.

When no message log file is specified, all output is displayed in the dbmlsync messages window. When a message log file is specified, less output is sent to the dbmlsync messages window.

You can control what information is logged to the message log file and displayed in the dbmlsync messages window using the -v option. Verbose output is not recommended for normal operation in a production environment because it can slow performance.
