NDB_PRINT_SYS_FIL(1)					       MySQL Database System					      NDB_PRINT_SYS_FIL(1)

NAME
ndb_print_sys_file - print NDB system file contents SYNOPSIS
ndb_print_sys_file file_name DESCRIPTION
ndb_print_sys_file obtains diagnostic information from a MySQL Cluster system file. Usage ndb_print_sys_file file_name file_name is the name of a cluster system file (sysfile). Cluster system files are located in a data node's data directory (DataDir); the path under this directory to system files matches the pattern ndb_#_fs/D#/DBDIH/P#.sysfile. In each case, the # represents a number (not necessarily the same number). For more information, see MySQL Cluster Data Node FileSystemDir Files[1]. Like ndb_print_backup_file and ndb_print_schema_file (and unlike most of the other NDB utilities that are intended to be run on a management server host or to connect to a management server) ndb_print_backup_file must be run on a cluster data node, since it accesses the data node file system directly. Because it does not make use of the management server, this utility can be used when the management server is not running, and even when the cluster has been completely shut down. Additional Options None. COPYRIGHT

NDB_DROP_INDEX(1)					       MySQL Database System						 NDB_DROP_INDEX(1)

NAME
ndb_drop_index - drop index from an NDB table SYNOPSIS
ndb_drop_index options DESCRIPTION
ndb_drop_index drops the specified index from an NDB table. It is recommended that you use this utility only as an example for writing NDB API applications--see the Warning later in this section for details. Usage ndb_drop_index -c connect_string table_name index -d db_name The statement shown above drops the index named index from the table in the database. The following table includes options that are specific to ndb_drop_index. Additional descriptions follow the table. For options common to most MySQL Cluster programs (including ndb_drop_index), see Options Common to MySQL Cluster Programs(1). Table 17.18. ndb_drop_index Options and Variables: MySQL Cluster NDB 7.2 +--------------------------+-----------------------------------+-------------------------------------+ |Format | Description | Added / Removed | +--------------------------+-----------------------------------+-------------------------------------+ | | Name of the database in which the | | | --database=dbname, | table is found | All MySQL 5.5 based releases | | | | | | -d | | | +--------------------------+-----------------------------------+-------------------------------------+ Warning Operations performed on Cluster table indexes using the NDB API are not visible to MySQL and make the table unusable by a MySQL server. If you use this program to drop an index, then try to access the table from an SQL node, an error results, as shown here: shell> ./ndb_drop_index -c localhost dogs ix -d ctest1 Dropping index dogs/idx...OK NDBT_ProgramExit: 0 - OK shell> ./mysql -u jon -p ctest1 Enter password: ******* Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Welcome to the MySQL monitor. Commands end with ; or g. Your MySQL connection id is 7 to server version: 5.5.35-ndb-7.2.15 Type 'help;' or 'h' for help. Type 'c' to clear the buffer. mysql> SHOW TABLES; +------------------+ | Tables_in_ctest1 | +------------------+ | a | | bt1 | | bt2 | | dogs | | employees | | fish | +------------------+ 6 rows in set (0.00 sec) mysql> SELECT * FROM dogs; ERROR 1296 (HY000): Got error 4243 'Index not found' from NDBCLUSTER In such a case, your only option for making the table available to MySQL again is to drop the table and re-create it. You can use either the SQL statementDROP TABLE or the ndb_drop_table utility (see ndb_drop_table(1)) to drop the table. COPYRIGHT
