Description:
I installed the cluster 4.1.7 version and running in the following configuration :
machine a :
1 ndb_mgmd
1 ndbd
1 mysqld
machine b:
1 ndbd
1 mysqld
I created 14 tables in the database and migrated the existing data
from the current single node mysql into the cluster. And I found out that one of the tables in which
the structure is follows :
CREATE TABLE `enquiry_temp` (
`ENQ_ID` int(11) unsigned NOT NULL auto_increment,
`E_SUBJECT` varchar(200) NOT NULL default '',
`E_FROM_DEPT` int(11) NOT NULL default '0',
`E_TO_DEPT` int(11) NOT NULL default '0',
`E_ENTRY_TS` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
`E_MESSAGE` text NOT NULL,
`M_ID` varchar(20) NOT NULL default '',
`ENQ_READF` tinyint(1) NOT NULL default '0',
PRIMARY KEY (`ENQ_ID`)
) ENGINE=ndbcluster DEFAULT CHARSET=utf8;
When I attempted insert the record as follows; the database got hang and no responsed at all
INSERT INTO `enquiry_temp` (`ENQ_ID`,`E_SUBJECT`,`E_FROM_DEPT`,`E_TO_DEPT`,`E_ENTRY_TS`,`E_MESSAGE`,`M_ID`,`ENQ_READF`) VALUES
(254,'Enquiry','CEDD','CSB','2004-09-01 07:51:00',
'Dear Sirs,\n\nI\'ve sent you an enquiry yesterday on the requirement of reporting of private investment.\n\nPlease send your reply to me at the following email address:\n\ncfchow1962@yahoo.com.hk\n\nThanks.',
'cfchow',1);
I found out that if I inserted this record into the single node mysql, there is no problem. And also if the E_Message field is varchar(255), there is no problem to insert into this cluster table.
I wonder if there is issues on inserting data into the "Text" field in mysql clustering. Or if there is something I can do to get around this problem.
How to repeat:
the config.ini is as follows :
[ndbd default]
NoOfReplicas= 2
MaxNoOfOrderedIndexes=1000
DataMemory=1024M
IndexMemory=512M
[mysqld default]
[ndb_mgmd default]
[tcp default]
[ndbd]
HostName= a
DataDir: /var/lib/mysql-cluster/
[ndbd]
HostName= b
DataDir: /var/lib/mysql-cluster/
[ndb_mgmd]
HostName= a
[mysqld]
[mysqld]
[mysqld]
and I set the characterset database variables as follows :
------------+
| Variable_name | Value |
+--------------------------+----------------------------------------------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/local/mysql-max-4.1.7-pc-linux-i686/share/mysql/charsets/ |
