different size under the two OS
Hello DBAs, Though this is not exactly a mysql problem, but I think this list may be helpful for my question. I have dumped a mysql data file, and scp it to another host. The current host is ubuntu-8.04, the remote host is ubuntu-9.10. As you can see below: The current host: $ md5sum fcm.0812.sql.gz ea08ec505c1b1724213538fed7483975 fcm.0812.sql.gz $ lsb_release -r Release:8.04 $ du -k fcm.0812.sql.gz 418080 fcm.0812.sql.gz The remote host: $ md5sum fcm.0812.sql.gz ea08ec505c1b1724213538fed7483975 fcm.0812.sql.gz $ lsb_release -r Release:9.10 $ du -k fcm.0812.sql.gz 417672 fcm.0812.sql.gz Though the files in two hosts have the same md5sum, but why they have different size with 'du -k' showed?

Re: does mysql support master to master replication

Subject: Question about database value checking
So, a problem popped up today that has caused us no end of hair-pulling, and
it brought to mind a similar issue that I found very, well, wrong.
If you have a table defined:
CREATE TABLE `tester_table` (
`acnt` varchar(20) NOT NULL DEFAULT '',
`method` varchar(10) NOT NULL DEFAULT '',
`card_num` varchar(100) NOT NULL DEFAULT '',
PRIMARY KEY (`acnt`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1
And try this:
INSERT INTO tester_table (acnt, method, card_num)
VALUES ('test1', 'push', NULL);
That fails. and gives a nice error. But:
INSERT INTO tester_table (acnt, method, card_num)
VALUES ('test1', 'push', 'A12345');
UPDATE tester_table set card_num = NULL WHERE acnt = 'test1';
That succeeds, but it puts an empty string into the card_num column. I
would have thought (hoped) that an error would be thrown in that case as
well. On a similar note, the following table:
CREATE TABLE `tester_table2` (
`acnt` varchar(20) NOT NULL,
`required` enum('NO','DETAILS','RESULTS') NOT NULL,
PRIMARY KEY (`acnt`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
Lets you insert:
INSERT INTO tester_table2 (acnt, required) VALUES ('A123456', 'THIS IS NOT
REAL');
Though it just puts an empty string into the required column.
Is there a setting for mysql to return errors in these cases? It seems silly
to set
up an enum column, or a not null column, and not have the possible values
enforced?
thanks,
andy

Re: Oracle, Sun and MySQL
I believe MySQL will still have great influence in Open Source area. The better is that MySQL will be a separate Company which has no relation to Sun and Oracle. Maybe Oracle can sell MySQL to a 3rd company. 2009/11/11 John Daisley john.dais...@butterflysystems.co.uk What I am more concerned about at the moment is how much the uncertainty over the deal is hurting MySQL? I was recently in a project planning meeting where MySQL was dismissed completely because nobody could give guarantees about where MySQL was going. There were a lot of concerns over where future development would go and a fear that when the deal goes through Oracle may slowly raise support and training costs to the sort of levels applicable to Oracle database products. These kind of arguments seem impossible to counter for as long as the uncertainty continues and I for one wish they would just resolve the situation either way very quickly because its hurting my business and open source software! regards John On Tue, 2009-11-10 at 23:50 -0600, Peter Brawley wrote: European regulators agree with Monty that the Oracle-Sun deal threatens database competition.

I would *never* use NFS storage for any DBMS (except for some testing): NFS access is slower than local disk access, and it adds more components to the critical path. So your operations get slower, reliability decreases, and (in case of any trouble) analysis becomes more difficult. I cannot imagine any setup where you have a machine strong enough to run your DBMS on it, but not capable of driving sufficient local disks. The typical argument for having centralized disks serving many machines is based on economies of scale (huge disks), flexibility (partitioning), and centralized management (RAID replacement, backup). There may be some merit to this in a specialized setup (NAS systems - I'm not convinced of them, but don't claim expert knowledge about them), but IMO not using general-purpose machines and NFS. Whatever the economical advantages during normal operation may be, you should not forget the huge costs you would incur if any in-between component breaks and your database stops operating. This may be tolerable for some applications, depending on the required availability, but simply intolerable for others. We are working on developing a custom protocol for MySQL clustering that takes care of all file management as part of the database clustering protocol, rather than a storage engine feature. Sorry, I don't get the meaning of this in sufficient detail to comment. What are the likely setup of a database storage ? Is it on RAW partition or on a File system ? That may depend on the storage engine used. MyISAM uses a file-per-table approach, so must be run on a file system; InnoDB may be able to use a raw partition (I'm not sure there); for others, I can't tell. Will ocfs2 be better used for mySQL as well, in a clustered environment ? I strongly doubt it. AIUI, the big advantage of cluster file systems is that they allow all machines to access and modify shared data. With a DBMS, you don't want to share data across machines, you want the database to be accessed only be the one machine (possibly multi-CPU, but shared memory) running the database processes, because on that machine you have the various database caches. Then, that machine makes the data available to all clients, so you get a logical sharing on a higher protocol level (SQL). To have multiple machines accessing the same database storage, you would first need some protocol to ensure cache coherency, and that is not contained in MySQL (in the general server). To use MySQL on multiple machines for the same data, you set up replication. The alternative approach would be to use MySQL Cluster, which is designed to hold the data in main memory (for extremely low latency) and to use the disk only for backup purposes. I would appreciate if any one share with me their thoughts on this. My comments above are based on my experience during DBMS development (including distributed DBMS), but not on any financial calculations or DBA work. Weigh them with other answers.

FW: Mysql C API character set
From: He, Gang
Sent: Wednesday, April 12, 2006 8:43 PM
To: '[EMAIL PROTECTED]'
Subject: Mysql C API character set
Hi,
I install MySQL server 4.1.12 in Redhat Linux in Japanese environment (
env LANG=ja_JP.UTF-8 ),
I setup MySQL server utf8 character set, the configuration is as
follows:
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1
default-character-set=utf8
[mysql.server]
user=mysql
basedir=/var/lib
[mysqld_safe]
err-log=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
Then, I start MySQL server, and type mysql command, the result is as
follows:
mysql show variables like 'char%';
+--++
| 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/share/mysql/charsets/ |
+--++
7 rows in set (0.00 sec)
But, I write a sample code using MySQL C API 4.1.10, the code is as
follows:
int main(int argc, char* argv[])
{
MYSQLm_conn;
MYSQL_RES *res;
MYSQL_ROW row;
mysql_init(m_conn);
mysql_real_connect(m_conn, localhost, root, 123456, mysql,
0, NULL, 0);
mysql_query(m_conn, show variables like 'character_set_%');
res=mysql_store_result(m_conn);
while((row=mysql_fetch_row(res))!=NULL)
{
printf(row[0]); printf(\t); printf(row[1]);
printf(\n);
}
mysql_free_result(res);
mysql_close(m_conn);
return 0;
}
The output result is as follows:
character_set_clientlatin1
character_set_connectionlatin1
character_set_database utf8
character_set_results latin1
character_set_serverutf8
character_set_systemutf8
character_sets_dir /usr/local/mysql/share/mysql/charsets/
I want to why character_set_client , character_set_connection and
character_set_results in the output result be latin1, not utf8 ?
If I want to change MySQL C API default value when the application call
mysql_real_connect() function, what I should do ?
Can I change MySQL C API default value via modifying '/etc/my.cnf '
configuration file ? ( I think that the best way is to modify
configuration file )
Thanks
Gang
Load data infile...
Hi, I have a question with regards to Load data infile... I have a .txt file containging only path names e.g C:\temp in the bodytext. this file is imported into the DB using load data infile. However, when i do a select * on that table which i've just imported, the result looks like this: C:temp\r so i assume what has happened is that when this file is imported into MYSQL, MYSQL treats any forward-slashes as codes. i.e. \t , \n , \r etc I have tried to put double quotes around the pathnames but it doesn't help. What should i do so that the path name does not get truncated?? thanks, i'd appreciate the help regards, Lisa _ Fynda på nätet!
