MySQL Cluster Administration Tools 0.3.1 (Default branch)

The MyCAT project is a toolset for managing MySQL/Linux servers, and could be helpful for anyone managing a network of *nix servers whether running MySQL Cluster, standard replication, or not running MySQL at all. At present, it contains three programs. rcall eases use and administration of groups (clusters) of *nix servers by creating logical groupings and a single location from which to run commands on all servers while entering it only once. It requires only an SSH connection. rep_mon is a replication monitor that notifies if a server is lagging or has encountered any errors. It handles any replication topology easily. binlog_mon monitors disk space used by MySQL binary logs, purging only when disk space is needed. It checks all slaves to ensure that purged files are not still being read by slaves. It has configurable behavior in the event that a slave still needs the oldest file.

Critical bugs were fixed in both binlog_mon and rep_mon. Image

NDB_SHOW_TABLES 					       MySQL Database System						   NDB_SHOW_TABLES

NAME
ndb_show_tables - display list of NDB tables SYNOPSIS
ndb_show_tables [options] DESCRIPTION
ndb_show_tables displays a list of all NDB database objects in the cluster. By default, this includes not only both user-created tables and NDB system tables, but NDB-specific indexes, internal triggers, and MySQL Cluster Disk Data objects as well. The following table includes options that are specific to the MySQL Cluster native backup restoration program ndb_show_tables. Additional descriptions follow the table. For options common to most MySQL Cluster programs (including ndb_show_tables), see Options Common to MySQL Cluster Programs(1). Table 17.26. ndb_show_tables Options and Variables: MySQL Cluster NDB 7.2 +--------------------------+--------------------------------------+-------------------------------------+ |Format | Description | Added / Removed | +--------------------------+--------------------------------------+-------------------------------------+ | | Specifies the database in which the | | | --database=string, | table is found | All MySQL 5.5 based releases | | | | | | -d | | | +--------------------------+--------------------------------------+-------------------------------------+ | | Number of times to repeat output | | | --loops=#, | | All MySQL 5.5 based releases | | | | | | -l | | | +--------------------------+--------------------------------------+-------------------------------------+ | | Limit output to objects of this type | | | --type=#, | | All MySQL 5.5 based releases | | | | | | -t | | | +--------------------------+--------------------------------------+-------------------------------------+ | | Do not qualify table names | | | --unqualified, | | All MySQL 5.5 based releases | | | | | | -u | | | +--------------------------+--------------------------------------+-------------------------------------+ | | Return output suitable for MySQL | | | --parsable, | LOAD DATA INFILE statement | All MySQL 5.5 based releases | | | | | | -p | | | +--------------------------+--------------------------------------+-------------------------------------+ | | Show table temporary flag | | | --show-temp-status | | All MySQL 5.5 based releases | +--------------------------+--------------------------------------+-------------------------------------+ Usage ndb_show_tables [-c connect_string] o --database, -d Specifies the name of the database in which the tables are found. o --loops, -l Specifies the number of times the utility should execute. This is 1 when this option is not specified, but if you do use the option, you must supply an integer argument for it. o --parsable, -p Using this option causes the output to be in a format suitable for use with LOAD DATA INFILE. o --show-temp-status If specified, this causes temporary tables to be displayed. o --type, -t Can be used to restrict the output to one type of object, specified by an integer type code as shown here: o 1: System table o 2: User-created table o 3: Unique hash index Any other value causes all NDB database objects to be listed (the default). o --unqualified, -u If specified, this causes unqualified object names to be displayed. Note Only user-created MySQL Cluster tables may be accessed from MySQL; system tables such as SYSTAB_0 are not visible to mysqld. However, you can examine the contents of system tables using NDB API applications such as ndb_select_all (see ndb_select_all(1)). COPYRIGHT
