Just rename slow_query_log, then "mysqladmin flush-logs"... http://dev.mysql.com/doc/refman/5.0/en/log-file-maintenance.html <Quote> The server creates a new binary log file when you flush the logs. However, it just closes and reopens the general and slow query log files. To cause new files to be created on Unix, rename the current logs before flushing them. At flush time, the server will open new logs with the original names. For example, if the general and slow query logs are named mysql.log and mysql-slow.log, you can use a series of commands like this: shell> cd mysql-data-directory shell> mv mysql.log mysql.old shell> mv mysql-slow.log mysql-slow.old shell> mysqladmin flush-logs At this point, you can make a backup of mysql.old and mysql-slow.log and then remove them from disk. </Quote> -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
