It is possible to specify a single value, but this is not optimal, because setting a single value limits searches to using only that algorithm. Youll also be dealing with binary log files when you are performing any kind of recovery operations in MySQL. block-search offset, -b offset Find the record that a block at the given offset belongs. However, when using the row-based logging format and -binlog-do-dbsales, changes made by the following update are not logged: USE prices; update rch SET amountamount-25; Even if the USE prices statement were changed to USE sales, the update statement's. include-master-host-port For the change master TO statement in a slave dump produced with the -dump-slave option, add master_host and master_port options for the host name and TCP/IP port number of the slave's master.

set-gtid-purged value This option enables control over global transaction ID (gtid) information written to the dump file, by indicating whether to add a SET @id_purged statement to the output. Seasoned IT professional by day, Jeff hopes to help other IT professionals by blogging about his experiences at night on his blog:. By default, it will use root as the username. The exception is when using -lock-all-tables or -master-data: In this case, the logs are flushed only once, corresponding to the moment that all tables are locked. Certifies for Critical Forensic Study of MySQL Log Files. This option is disabled by default because histogram generation for large tables can take a long time. The server issues an error message and does not start if the binary log and relay log file base names would be the same. The pipeline extracts the contents of binlog-files_1.gz, pipes the binary log files to mysqlbinlog as standard input, and pipes the output of mysqlbinlog into the mysql client for execution: shell gzip -cd binlog-files_1.gz./mysqlbinlog -./mysql -uroot -p You can specify.

The only permitted value for this option is ansi, which has the same meaning as the corresponding option for setting the server SQL mode. The built-in tee also logs everything that is printed on the screen, whereas the Unix tee used with pager does not log quite that much. The -ssl-fips-mode option differs from other -ssl- xxx options in that it is not used to establish encrypted connections, but rather to affect which cryptographic operations are permitted. opt This option is shorthand; it is the same as specifying -add-drop-table -add-locks -create-options -disable-keys -extended-insert -lock-tables -quick -set-charset. spassword password, -P password The password to use when connecting to the server as the superuser. flushlog Flush logs after all tables are locked.

This changes the password to new-password for the account that you use with mysqladmin for connecting to the server. This technique is used to recover from a crash when you have an old backup (see Section.5, Point-in-Time (Incremental) Recovery Using the Binary Log ). Another case which may not be self-evident occurs when a given database is replicated even though it was not specified when setting the option. This option is deprecated and will be removed in a future MySQL release. replicate-do-db db_name Creates a replication filter using the name of a database. In most cases, Transaction Data is visible at the bottom of the interface. repair, -r Perform a repair that can fix almost anything except unique keys that are not unique. When binary logging is enabled on a replication slave, the combination of the -replicate-same-server-id and -log-slave-updates options on the slave can cause infinite loops in replication if the server is part of a circular replication topology. For example, you can issue them from the mysql client program. Suppose that the binary log just described was created using row-based logging rather than statement-based logging.


Open tables The number of tables that currently are open. When using MySQL replication, masters and slaves know each other's uuids. Help (h) Display this help. This helps prevent accidents. On a slave, it is the difference of the end execution time on the slave minus the beginning execution time on the master. Flush-hosts Flush all information in the host cache. The change master TO statement reads the values of Relay_Master_Log_File and Exec_Master_Log_Pos from the show slave status output and uses them for master_LOG_file and master_LOG_POS respectively. Sql Enter password: We should have our table back and the first row: mysql select * from uptimemadeeasy; uptimeint uptimechar row row in set (0.00 sec) Now, lets go through the binary logs using the mysqlbinlog command mysqlbinlog uptimemysql-bin.000002.

complete-insert, -c Use complete insert statements that include column names. The heartbeat interval defaults to half the value of -slave-net-timeout, and it is recorded in the master info log and shown in the Performance Schema table. For example, if you use -replicate-wild-do-tablefoo., database-level statements are replicated if the database name matches the pattern foo. If you require routines to be re-created with their original definer, dump and load the contents of the oc table directly as described earlier. log-error file_name Log warnings and errors by appending them to the named file.

test, mysql binary log options -t Do not actually pack the table, just test packing.

Examples To make a backup of an entire database: shell mysqldump db_name backup-file. unpack, -u Unpack a table that was packed with myisampack. description, -d Print some descriptive information about the table. These may be used when dumping stored programs to preserve their character encodings. This can also be added to /etc/f expire_logs_days. Without -force, mysqlimport exits if a table does not exist.

u Perform an update operation. This option is ignored for accounts that do not authenticate with that plugin. To obtain information about the key distribution, use a myisamchk -description -verbose tbl_name command or the show index from tbl_name statement. These -ssl-fips-mode values are permitted: OFF: Disable fips mode. This means that when the routines are reloaded, they will be created with the timestamps equal to the reload time. Additionally, tee file logging can be turned on and off interactively from within mysql. no-autocommit Enclose the insert statements for each dumped table within SET autocommit0 and commit statements.

See Section.2.5, The Server SQL Mode. This means that before.1.8, when routines are reloaded, they will be created with the definer set to the reloading user. Memory in use The amount of memory allocated directly by mysqld. When creating multiple-row insert statements (as with the -extended-insert or -opt option mysqldump creates rows up to -net-buffer-length bytes long. Processing binary logs this way using multiple connections to the server causes problems if the first log file contains a create temporary table statement and the second log contains a statement that uses the temporary table. max-allowed-packet value The maximum size of the buffer for client/server communication. replicate-rewrite-db from_name - to_name Tells the slave to create a replication filter that translates the default database (that is, the one selected by USE ) to to_name if it was from_name on the master. If you need to put the relay logs in some area other than the data directory because your relay logs tend to be very large and you do not want to decrease max_relay_log_size. The -opt option (and hence -quick ) is enabled by default, so to enable memory buffering, use -skip-quick. If you are using this option to repair tables, it tries to repair only the index tree. The default value for this option is the port number actually used by the slave (Bug #13333431). See Section.1.11, Server SQL Modes. If you want to recover a table, this is the option to try first.


port port_num, -P port_num The TCP/IP port number to use for the connection. (For a workaround, see Downgrade Notes ; you can convert triggers to be compatible with older servers.) -where' where_condition -w ' where_condition ' Dump only rows selected by the given where condition. This space is not needed if you do a repair with -quick; in this case, only the index file is re-created. debug N mysql binary log options Specify the debug level. With this setting, hashing is used for any searches that do not use a primary or unique key. Some of the commands take an argument following the command name. After packing a table, it becomes read-only. You can also create such a filter by issuing a change replication filter replicate_wild_DO_table statement. No endspace Do not store endspace. If this value is zero (the default the size at which relay log rotation occurs is determined by the value of max_binlog_size.
