Replication with failover
Hi, Anybody have any experience with setting up MySQL replication with dynamic failover, preferably using keepalived (http://www.keepalived.org)? What we need is a system so that if the master server dies one of the slaves will become the master. It looks like it should be possible, and merely involves a bit of scripting to glue it all together, but I was hoping somebody would have created such scripts already so I don't screw it up myself :) tia -Simon -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: Export from Access
I recently exported a large Access database to MySQL using MyODBC. It took me a while to figure out that MyODBC was the thing to try, but once I did tried it, it only took me a few minutes to do the export.

Re: MySQL Administrator Broke MySQL
Nevermind. I figured it out. It somehow corrupted the db table in the mysql db. I blew that away and recreated it with just root access to all of the dbs and it works now.

Re: Installing MySQL 4.1.12 on Mandrake 10.1
Hello. My questions are: Is there other files besides just the server and the client that I would need to install to get MySQL to work on Mandrake v10.1? Your data directory should contain mysql database prepared with mysql_install_db script. See: http://dev.mysql.com/doc/mysql/en/unix-post-installation.html Are there other issues with 4.1.12 that I have not fully explored that might prevent this from being installed? In your case - no. Finally if I upgraded this system to 4.1.12 now that 4.0.20 is installed would I wind up having the same problems? You should read: http://dev.mysql.com/doc/mysql/en/upgrading-from-4-0.html But I suggest you to remove all mysql instances from you box and perform a clean install of 4.1.12 using official binaries. I have a new test Linux server with Mandrake 10.1 installed that I was trying to install MySQL version 4.1.12 on today. Once I had installed the software, whenever I tried to start MySQL on this server I was getting the error message [ERROR] Fatal error: Can't open privilege tables: Table 'mysql.host' doesn't exist when I tried to run the 'mysql_setpermissions' script and was getting the same result. After this failed I decided to try the MySQL installation files that came with the operating system which were Version 4.0.20 and this version worked fine. When I was installing the 4.1.12 version I was simply going with a minimal install of just the server package and the clients. When I ran the installation package from Mandrake it installed other files that from my reading of the MySQL manual I did not think that I needed. My questions are: Is there other files besides just the server and the client that I would need to install to get MySQL to work on Mandrake v10.1? Are there other issues with 4.1.12 that I have not fully explored that might prevent this from being installed?

CHECK TABLE shouldn't produce it: http://dev.mysql.com/doc/mysql/en/myisamchk-syntax.html If mysqld is running, you must force it to flush any table modifications that are still buffered in memory by using FLUSH TABLES.

4.1.12 Crashing on Mandrake 10.1
Hi, I just upgraded from 4.1.11 (which worked fine, and stil does if I downgrade) to 4.1.12 and the first query crashes the server. This query is executed via DBD::mysql, when run via the mysql client it works OK though. I presume this must be some library conflict but has anyone got any idea what? I tried to follow these instructions: http://dev.mysql.com/doc/mysql/en/using-stack-trace.html But there isn't a mysqld.sym.gz and nm -n mysqld /tmp/mysqld.sym (and nm -n -D ) says nm: mysqld: no symbols Error Log -- mysqld got signal 11; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail. key_buffer_size=268435456 read_buffer_size=1044480 max_used_connections=2 max_connections=100 threads_connected=1 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 466543 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. thd=0x892bba0 Attempting backtrace.

RE: varchar(10) to decimal
I was all set to tell you why 16.125 became 16.12 when I ran the test on our
production box. It looks like some where between 4.0.20 and 5.0.4 the ALTER
TABLE to a decimal data type changed from truncation to rounding.
Redhat MySQL 4.0.20 truncates all
Windows XP MySQL 5.0.4 Rounds with Windows algorithm
I suspect a MySQL 5.0.4 on Linux would round with Linux alorithm but I don't
have one to test.
See following:
The decimal(6,2) tells MySQL to round all values to 2 places and store the
results in a decimal field. MySQL uses the Round routines of the host.
On a Windows box
16.125 = 16.13
16.135 = 16.14
On a Linux/Unix box
16.125 = 16.12
16.135 = 16.14
Here it is on windows
mysql select * from dcml;
++
| a |
++
| 16.00 |
| 16.25 |
| 16.125 |
| 16.135 |

Thanks Shawn! Peter Brawley [EMAIL PROTECTED] wrote:Seena, That data is for one date. To test Shawn's 2-stage query I'd need a data for several days. Without your tables and data, I tried Shawn's algorithm on a test database we use a lot, nwib, which is a MySQL port of the widely used (and copied) Microsoft Northwind database. It has customers, orders, orderdetails, payments etc, and it's populated. Your question, who are the top ten spammers per day? is logically equivalent, in nwib, to: what customers made the top ten number of orders for any given year? Translating Shawn's method to nwib.orders gives us: CREATE TABLE orderstats ( yr SMALLINT NOT NULL , rank INT AUTO_INCREMENT, customerID CHAR(5) NOT NULL, ordercount INT UNSIGNED NOT NULL, PRIMARY KEY(yr,rank) ); INSERT orderstats ( yr, customerID, ordercount ) SELECT YEAR(orderdate) AS yr, customerID, COUNT(customerID) AS ordercount FROM orders GROUP BY yr, customerID ORDER BY yr,ordercount DESC which, as Shawn says, auto-populates orderstats.rank for each group. After the above executes, SELECT * from orderstats WHERE rank = 10 gives the top ten ordering customers per year, as expected. So I am unclear why the algorithm does not work for your spam table.

Different TIMESTAMP columns
I 'm writing a webapplication in Java that allows users to store bookmarks. The system scans these pages for differences at user-selected intervals. At another user-selected interval, the system sends notification mails about changed bookmarks. The bookmark table provisionally looks like this: CREATE TABLE bookmark ( bookmark_id INTEGER NOT NULL AUTO_INCREMENT, bookmarkname VARCHAR (80) NOT NULL, url VARCHAR (150) NOT NULL, folder_id INTEGER NOT NULL, last_scanned TIMESTAMP NOT NULL, PRIMARY KEY (bookmark_id), FOREIGN KEY (folder_id) REFERENCES folder(folder_id) ON DELETE CASCADE) TYPE = InnoDB; I want to add another TIMESTAMP column, last_notified. But whenever I insert a new bookmark, the first TIMESTAMP column will be set, the other will be -00-00 00:00:00. When they get mapped by the iBatis framework to Java objects, I get an exception that aTimestamp object can not be created with -00-00 00:00:0 Is there a way I can set them both when the bookmark is created? I rather not set one of them to NULL, because that would imply a lot more code to check if a user should be notified or a bookmark should be scanned. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Restoring a database from binlogs
Hey all, I've got a big problem. Seems one of our programmers decided to write a script that deletes all records from a log table older than 3 months. Problem is, we need old data from this log to reconcile our customer accounts. Our backups only go back 2 weeks. What I do have however is replication running and therefore old binlogs. These binlogs go back as far as Nov 12, 2004. The cleaning of the log table didn't start until about a month ago and has deleted any data prior to Jan 18, 2005. The only snapshot I can find of the database is from Sept 10, 2004. So.. (shooting off into the dark) I have binlogs starting from Nov 12, a snapshot from sept 10th. Is there some way anyone can suggest that I can reconstruct the database table with what I have?

Re: varchar(10) to decimal
4.1.11 truncates as well, and not just for ALTER TABLE. My tests show
mysql handles input to a DECIMAL(M,D) column inconsistently: It rounds
if the input is numeric, but it truncates if the input is a string. I'm
guessing that because mysql 4.x stores DECIMALs as strings, it handles
the string case with a simple string copy, hence the truncation. I
think that's a bug, so I reported it as such
http://bugs.mysql.com/10719. We'll see what the developers think.
The different behavior in 5.0.4 is no doubt a result of the change made
to DECIMAL in 5.0.3,
http://dev.mysql.com/doc/mysql/en/precision-math-decimal-changes.html,
though this particular aspect of the change doesn't seem to be
documented. Starting with 5.0.3, DECIMAL is no longer a string, so I'd
bet the input string is converted to a number first, which means it gets
rounded before it is assigned, as is the case in mysql 4.x

That is why they are not normally used to store manually updated values. To store a date+time value and not have it overwritten with the time and date of the next update to the record, you should use a DATETIME column. The exact behavior of timestamp columns depends on if they are the only one on a table and which version of MySQL you are running.

That is why they are not normally used to store manually updated values. To store a date+time value and not have it overwritten with the time and date of the next update to the record, you should use a DATETIME column.

RE: Restoring a database from binlogs
Interesting idea. So if I take the table from Sept 10th and then do that with the binlog I'll be missing about 2 months worth of data because my earliest binlog file is Nov 12th.

Since you do have the binlogs, extract them to text files and write a perl script to figure out what insert/update statements you need. I've done it before and it took some time to make sure I grabbed the correct update/insert statements. As a side note, it might be worth the $$$ to setup a replication server that you can take off-line to do cold backups. When you make the backups, you know exactly what time and what logfile and posistion it was at. The replication server in most cases doesn't need near the processing power the primary db does.
