Startup Options Used with Binary Logging. System Variables Used with Max_binlog_size not working Logging.
You can use the mysqld options and system variables that are described in this section to affect the operation of the binary log as well as to control which statements are written to the binary log. The following list describes startup options for enabling and configuring the binary log. System variables used with binary logging are discussed later in this section.
The server logs all statements that change data to the binary log, which is used for backup and replication. The option value, if given, is the base name for the log sequence.
The server creates binary log files in sequence by adding a numeric suffix to the base name. This is a known issue; see Bug for more information. The index file for binary log file names. If max_binlog_size not working argument is given, the option sets the variable to 1. This is the old name for --log-bin-trust-function-creators. It is recognized for backward compatibility but its use results in a warning.
The options in the following list affect which statements are written to the binary log, and thus sent by a replication master server to its slaves. Max_binlog_size not working are also options for slave servers that control which statements received from the master should be executed or ignored. This option affects binary logging in a manner similar to the way that --replicate-do-db affects replication.
All other databases that are not explicitly mentioned are ignored. If you use this option, you should ensure max_binlog_size not working you do max_binlog_size not working only in the default database.
The server uses the database named in the statement not the default database to decide whether it should log the statement. An example of what does not work as you might expect: It is also faster to check only the default database rather than all databases if there is no need. Another case max_binlog_size not working may not be self-evident occurs when a given database is replicated even though it was not specified when setting the option.
To log multiple databases, use this option multiple times, specifying the option once for each database to be logged. Because database names can contain commas, the list will be treated as the name of a single database if you supply a comma-separated list.
This option affects binary logging in a manner similar to the way that --replicate-ignore-db affects replication. To ignore multiple databases, max_binlog_size not working this option multiple times, specifying the option once for each database to be ignored. Testing and debugging options. The following binary log options are used in replication testing and debugging. They are not intended for use in normal operations.
This option is max_binlog_size not working internally by the MySQL test suite for replication testing and debugging.
The following list describes system variables for controlling binary logging. They can be set at server startup and some of them can be changed at runtime using SET. Max_binlog_size not working options used to control binary logging are listed earlier in this section. Whether the binary log is enabled.
This variable reports only on the status max_binlog_size not working binary logging enabled or disabled ; it does not actually report the value to which --log-bin is set. Whether updates received by a slave server from a master server should be logged to the slave's own binary log. Binary logging must be enabled on the slave for this variable to have any effect. The minimum value is The maximum and default values are 4GB on bit platforms and max_binlog_size not working exabytes on bit platforms.
The maximum recommended value on bit platforms is 4GB; this is due to the fact that MySQL currently cannot work with binary log positions greater than 4GB. If a write to the binary log causes the current log file size to exceed the value of this variable, the server rotates the binary logs closes the current file and opens the next one.
The minimum value is bytes. The maximum and default value is 1GB. A transaction is written in one chunk to the binary log, so it is max_binlog_size not working split max_binlog_size not working several binary logs.
There is one write to the binary log per statement if autocommit is enabled, and one write per transaction otherwise. A value of 1 is the safest choice because in the event of a crash you lose at most one statement or transaction from the binary log. However, it is also the slowest choice unless the disk has a battery-backed max_binlog_size not working, which makes synchronization very fast.
The server relies on the operating system to flush the file contents occasionally as for any other file. Permitted Values bit platforms.
