Newbie: MySQL cluster configuration
hi, i want to configure a two-machines mysql clusters. i have compiled from source by enabling the clustering feature with no problem at all. i read the documentation on mysql. but, i am not understanding on how to make a simple mysql cluster. basically, i just want to have a kickstart. that's all. i have a config.ini file at my /usr/local/mysql/mysql-cluster, as such [NDBD DEFAULT] NoOfReplicas= 1 [MYSQLD DEFAULT] [NDB_MGMD DEFAULT] [TCP DEFAULT] [NDB_MGMD] HostName= node1.mysql [NDBD] HostName= myhost.example.com DataDir= /var/lib/mysql-cluster [MYSQLD] [MYSQLD] [MYSQLD] then, when i start ndb_mgm, i get this. NDB SHOW Cluster Configuration - [ndbd(NDB)] 1 node(s) id=2@127.0.0.1 (Version: 3.5.3, Nodegroup: 0, Master) [ndb_mgmd(MGM)] 1 node(s) id=1@127.0.0.1 (Version: 3.5.3) [mysqld(API)] 3 node(s) id=3@127.0.0.1 (Version: 3.5.3) id=4 (not connected, accepting connect from any host) id=5 (not connected, accepting connect from any host) now, i have my second machine, let's called it node2.mysql. i have no ideas to join the ndb node2.mysql into the mgmd at node1.mysql. pls guide me. i read someone had mentionedNdb.cfg file. i have not noticed that file in my machine. weird pls give me more information and ideas.thanks -- Mr. Hiu Yen Onn System Administrator Shin Yang Group of companies Website: www.shinyang.com.my Email: [EMAIL PROTECTED] Tel: (6085)656699 ext.253 -- Butterfly de Micro$oft - The King of Desktops Penguin de Linux - The Mighty Lord of Servers -- -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
problem with queries
hello All,
can anybody tell me how to correct this problem:
1. I use queries like that:
select /*! SQL_BUFFER_RESULT */ klient.logo, klient.klientid,
klient.klientnazwa, klient.struktura, concat(kodpocztowy,' ',miejscowosc)
miasto, aparatnumer, concat(ulicaskrot,' ',ulicanazwa,' ',posesja)
ulica,concat('woj. ',wojewodztwo,', powiat: ',powiat, ', gmina: ', gmina)
wojpow, klientbranze branza, email, www, wizytowka from klient [where conditions
or no conditions]
2. we upgraded PHP to 5.0.3, installed Zend Optimizer and upgraded MySQL from
4.0.20 to 4.1.7
3. after upgrading when I try to execute query from [1.] I have error:
MySQL Error: 1270 (Illegal mix of collations (latin2_general_ci,IMPLICIT),
(latin1_swedish_ci,COERCIBLE), (latin2_general_ci,IMPLICIT) for operation
'concat')
Session halted.
4. system variables are like this:
variable session global
back log 50 50
basedir /usr/local/mysql/ /usr/local/mysql/
binlog cache size 32768 32768
bulk insert buffer size 8388608 8388608
character set client latin1 latin2
character set connection latin1 latin2
character set database latin2 latin2
character set results latin1 latin2
character set server latin2 latin2
character set system utf8 utf8
character sets dir /usr/local/mysql/share/mysql/charsets/
/usr/local/mysql/share/mysql/charsets/
collation connection latin1_swedish_ci latin2_general_ci
collation database latin2_general_ci latin2_general_ci
collation server latin2_general_ci latin2_general_ci
how to proper correct that?
best regards in advance

table becomes locked and lock is never released
Hi, I have the following problem: One table becomes locked and the lock is never released. I do not use any form of LOCK TABLES to lock the table, I only do SELECT, INSERT and UPDATE queries. The table stays locked until the server reaches max_connections and server becomes unavailable. The problem occurs quite randomly: sometimes once in every 2-5 days, but sometimes 2-3 times during one hour. I think that there is a problem with one table (atfoorum.teemad), but I don't know to solve it. The problem might be something to do with the fact that I converted the table from latin1 to utf8 and started inserting russian characters. I have saved many times the output of 'show processlist' before i killed the server. It looks always the same: The first query is SELECT query in the state 'Sorting result'. This select query queries from multiple tables, including 'atfoorum.teemad' using LIKE. The next queries in the processlist are UPDATES in the 'Locked' state (all queries deal with table 'atfoorum.teemad'). I deleted the database and rebuilt it using mysqldump, but it did not help. Has anyone had this kind of problem and/or knows how to solve this issue ? I use 4.1.1-alpha-Max-log, the OS is RedHat AS 3.0. The server is dedicated to run only MySQL. Server parameters: 4GB RAM 2x2.8Ghz P4 Xeon SCSI hard drives 1 rpm in RAID 1 array.

Michael, Gleb, thanks a lot for your hints! Now I know that default database means current database.

Help with a join query please!
Hi, I have (among others) three tables in my database that i am struggling with a join query on. The database holds dates for Bookings. If Users are Allocated to a particular Project they can be booked. However if a user is booked but then unallocated I want to be able to display all peolple allocated to that project plus the person originally booked. Here are my efforts so far: SELECT U.User_ID, U.User_Firstname, U.User_Lastname FROM Allocations A, Users U LEFT JOIN Bookings B ON B.User_ID = U.User_ID AND B.Booking_ID = '4512' WHERE U.User_ID = A.User_ID AND A.Project_ID = '11' ORDER BY User_Firstname; I am using version 3.23.54. The query works but doesnt return the required values. The query returns all of the users allocated to the project, not the user who is currently booked but not allocated to the project.

Daniel, it is simply processing big SELECT queries. Maybe their optimization changed lately? You should tune your queries.

It would be very nice to have this in MySQL. I agree that it would be nice to have this feature sometimes but I haven't seen it on any relational database I've ever seen. I'm guessing that it isn't in the SQL standards that most of the database companies use in developing their products. I would suggest two possible approaches, neither of which is likely to give you what you want any time soon: - lobby the relational database vendors to include this sort of syntax in the next version of the SQL standard - lobby one vendor, maybe MySQL, to support the syntax as an extension of the standard. If they implement it and it proves popular, maybe this will give the other vendors an incentive to include it as standard syntax in some future version of the standard Getting a single vendor to include the syntax as an extension might work relatively quickly - say, a year or two - but it might take a good bit longer before it is adopted by other vendors as a standard feature of SQL. Sorry, I'm sure that is not nearly as fast as you'd like to see this feature adopted but I think that is the only way you are likely to see it happen. The only approach that I can imagine that would be considerably quicker would be for you to find or write some kind of preprocessor that allows for this syntax; then, you could write select * except colQ, colZ and the preprocessor would turn it into select colA, colB, colC, ... colP, colR, colS, ... colY. I've never tried to write a preprocessor so I can only begin to imagine how much work it might be to write, test, and implement.

Problems with replication restarting
Hi all, I originally posted this to the replication list, but as I haven't yet received a response, I thought I'd try my luck here... I'm having some troubles with replication, in particular restarting a slave. I'm using MySQL 4.0.22 for the slave, and 4.0.21 as the master. I've followed the instructions as per the manual, and replication is now working fine. However, when I restart the slave (through init scripts, or when rebooting the server etc.), instead of continuing on from where it left off, it appears to start again from the beginning. This is confirmed by watching the value of Relay_Log_Pos from SHOW SLAVE STATUS\G. I suspect this has something to do with the fact that when the slave is set up (as per the instructions at http://dev.mysql.com/doc/mysql/en/Replication_HOWTO.html), the CHANGE MASTER statement is issued, and this sets the MASTER_LOG_POS and MASTER_LOG_FILE paramaters to their initial values. It appears that these values do not get changed or updated after the slave is started. Could someone please inform me whether this is abnormal behaviour (it would seem to be, as each restart of the slave would cause it to lag further and further behind the master), and if so, how to fix it ?

Re: LOAD DATA INFILE
Hi Rob, LOAD DATA INFILE is not a very verbose command. It doesn't spill out the exact root cause of the error. Forgive me, if I seem to be wrong for anybody who had a different opinion. mysqlimport is a wrapper around LOAD DATA INFILE with a lot of command line options. You might try your luck using the mysqlimport command which does the same for you. But I am not sure if it really helps you with more verbose output. The problem might be due to any of the following problems: - The data in the file needs to be in a format that mysql understands. With mysqlimport you can specify the column and record delimiters as required. - Escape characters need to be defined when you do a mysqlimport so that the data is not mistaken as a delimiter by mysql. - Also make sure that there are no foreign key violations in your target database.

Unique IDs
I'm working on a rather large database with many cross-linked tables currently using auto increment IDs. The system is primarily a web based system, however, there will be times that the system will be run as a stand alone server...meaning no internet connection is available. The question arises that if someone enters information to the database on the website, while others are entering information on the local database, what is the best way to merge the data? I would imagine that we would run into many duplicate auto increment IDs. I'm sure that for one table insert, this would not be a problem as I could store the SQL statement in a text file without the ID specified, and run it as a batch process on the live server when we get connectivity. But I don't have a handle on how to update the sub tables that have a FK pointer. Any ideas?

cluster problem
Hi, I'm currently experimenting with Cluster for the first time (using mysql 4.1.8 under Red Hat 9.) I've set up a combined manager and API node, and three storage nodes. It all seems to be working fine (I can create tables using ENGINE=NDB and see all three storage nodes from within the ndb_mgm display. I'm now trying to populate a large table (it should ultimately have 6M rows.) The load program gets up to about 62K rows, then dies with the error: DBD::mysql::db do failed: The table 'radlog' is full So far, I've tried increasing the DataMemory value for all the storage nodes, and setting autocommit on the DBI handle (this was admittedly a shot in the dark.)

RE: Problems with replication restarting
First of all MySQL replication do not mismatch position in simply starting and stopping the slave as long as you have all relay and info files. Secondly, change master recreates the master.info file. Third...one can implement the log_position table on slave inserting a record every minute to record the details from show master logs and show slave status commands. This will give you exact position every minute in your database and one can run change master anytime to play with the position. I have never seen MySQL replication changing position in just starting and stopping slave.

Boolean search showing zero results in error
I have hit a snag in setting up a Boolean search; my query is returning 0
results when there are definitely five matches in my table.
My query is set up as follows:
SELECT * FROM resources WHERE MATCH (organization_name, description) AGAINST
('keep' IN BOOLEAN MODE);
'Keep' is a word that shows up 3 times in the organization_name field and 2
times in the description field in my table. There are 122 rows in the table,
so this 0 result is clearly not because of the 50% threshold (which I think
doesn't apply to Boolean searches anyway?)
Other background information: I have set organization_name and description
as the fulltext index, organization_name is a VAR CHAR field of 100,
description is a TEXT field, all of the organization_name entries are
minimum of 3 words, and description entries are a minimum of about 100
words.
If I make it a basic search like this:
SELECT * FROM resources WHERE organization_name LIKE %keep% OR description
LIKE %keep%;
Then I get the correct results back. If I set it as a fulltext search (not
boolean) I get 0 results back. If I add an * into my Boolean search
(AGAINST ('keep*' IN BOOLEAN MODE);) I get 1 result (and not the 5 I should
be getting).
Is my first query written wrong? What am I missing here?
Thanks in advance for your help.

Re: Boolean search showing zero results in error
keep is a full-text stopword, by default, which means it isn't indexed.
You'll need a custom stopword list if you want keep to be indexed. See
the manual for details
http://dev.mysql.com/doc/mysql/en/Fulltext_Fine-tuning.html.
The default list of stopwords is in myisam/ft_static.c in a source distribution.

MyISAM vs. InnoDB for heavily-indexed, read-mostly data
I'm new to MySQL and I was wondering which storage engine is the best choice for heavily-indexed, read-mostly data. From skimming over the documentation, it seems that MyISAM is a better choice since it doesn't have the transactional overhead. Yet I'm worried that it's becoming depricated and won't be supported in future versions. I need the highest read performance possible, with many indexes and joins. It has to be able to cache query results in memory to service a large number of concurrent requests per second. Which way to go? What's the pros and cons of each engine for my particular situation?

create table itis.kingdoms
(

tried importing it into my database with phpMyAdmin
but got this error message:
SQL-query :
{ DATABASE itis delimiter | } GRANT dba TO itis
MySQL said:
#1064 - You have an error in your SQL syntax. Check
the manual that corresponds to your MySQL server
version for the right syntax to use near '{ DATABASE
itis delimiter | }
grant dba to itis' at line 1
So what's the easiest way to get all these tables
imported into my database?
Thanks.
