Ndb_Cpcd; Automate Testing For Ndb Development; Ndb_Delete_All; Delete All Rows From An Ndb Table - Oracle 5.0 Reference Manual

Examples
1. To obtain the node ID and type of each node in the cluster:
shell> ./ndb_config --query=id,type --fields=':' --rows='\n'
1:ndbd
2:ndbd
3:ndbd
4:ndbd
5:ndb_mgmd
6:mysqld
7:mysqld
8:mysqld
9:mysqld
In this example, we used the
colon character (:), and the
output.
2. To produce a connectstring that can be used by data, SQL, and API nodes to connect to the
management server:
shell> ./ndb_config --config-file=usr/local/mysql/cluster-data/config.ini \
--query=hostname,portnumber --fields=: --rows=, --type=ndb_mgmd
192.168.0.179:1186
3. This invocation of
the values for each node's ID and host name, and its DataMemory, IndexMemory, and
parameters:
shell> ./ndb_config --type=ndbd --query=id,host,datamemory,indexmemory,datadir -f ' : ' -r '\n'
1 : 192.168.0.193 : 83886080 : 18874368 : /usr/local/mysql/cluster-data
2 : 192.168.0.112 : 83886080 : 18874368 : /usr/local/mysql/cluster-data
3 : 192.168.0.176 : 83886080 : 18874368 : /usr/local/mysql/cluster-data
4 : 192.168.0.119 : 83886080 : 18874368 : /usr/local/mysql/cluster-data
In this example, we used the short options
separator, respectively.
4. To exclude results from any host except one in particular, use the
shell> ./ndb_config --host=192.168.0.176 -f : -r '\n' -q id,type
3:ndbd
5:ndb_mgmd
In this example, we also used the short form
Similarly, you can limit results to a node with a specific ID using the
