Problem with mysql
Hello I have installed mysql, apache and phpmyadmin on a new server running Fedora Core 12. For some unknown reason I cannot connect to the local host using a full hostname. This is what I have done: r2-d2# mysql -u root -p grant all on . to 'root'@'r2-d2' idenfified by 'secret-password'; grant all on . to 'root'@'r2-d2.dahl-stamnes.net' idenfified by 'secret-password'; flush privileges; quit r2-d2# mysql -h r2-d2 -u root -p (works) r2-d2# mysql -h r2-d2.dahl-stamnes.net -u root -p ERROR 1130 (HY000): Host 'r2-d2.dahl-stamnes.net.' is not allowed to connect to this MySQL server Then I did: r2-d2# mysql -u root -p grant all on . to 'root'@'jedi.dahl-stamnes.net' idenfified by 'secret-password'; jedi# mysql -h r2-d2.dahl-stamnes.net -u root -p (works) I have checked the local DNS and 'r2-d2' and 'r2-d2.dahl-stamnes.net' resovl to the same IP-addresse.

tmp tables
Hi; I have a shopping cart that will spawn a tmp table for every shopping cart instance. Would it be better to create a separate database for these instead of having them in the same database as all the other tables for the shopping cart?

Can't open file error number 24
Hi, We have been using MYSQL in our dedicated server for long time without problem, Suddenly we noticed an error stating Can't open file error number 24. When we rebooted the machine , MYSQL started working again fine. We have to fix this problem not to happen again, We have Opened tables: 18,500 maximum connection :160 table_catche : 320 When I checked for open_files_limit in mysql administrator , it seems to be disabled...Do I need to enable that and set the value? or Will it take default value 0 and use max connetion* 5 or max connection+table_cache*2 ?

problem, Suddenly we noticed an error stating Can't open file error number 24. If I recall correctly, error 24 means the disk partition is full.

If open_files_limit is currently 0, then your OS won't let you change the value, and you will have to lower the table_open_cache variable to stay under whatever the OS limit is. Since Windows is the only OS where open_files_limit is 0, you might want to try upgrading to MySQL 5.5 which uses a different method of opening files (5.4 and older could only open 2048 files at once on Windows).

reaction to mysql remote buffer overflow 0day being posted online?
Apologies in advance for spamming the list. My name is Brian Krebs, and I'm a investive reporter who writes about computer security issues. I've just interviewed the founder of a Russian security firm who says he's getting close to posting pointers to and in some cases exploits for a large number of 0day vulnerabilities in database and web server products, including at least one -- possibly two -- remote buffer overflows in mysql. I've interviewed clueful folks who vouch for this guy's chops, so I know he's not making this up. As you may have guessed by now, I'm fishing for a comment or response from the mysql/dev community about this. Can I trouble someone to ping me back at krebsonsecur...@gmail.com ?

MySQL InnoDB memory performance tuning
Hi, I have a fairly small (data dir is 1.2GB) InnoDB database managed by MySQL 5.4.3-beta on an 8-core x86_64 Linux box with 16GB RAM. I'd like to use as much of the memory as possible, but despite specifying (e.g.) --innodb-buffer-pool-size=30, mysql only ever takes up 374M of resident memory (though the virtual memory totals about 3.5GB). Is there another setting that I should consider tweaking which will actually fully utilize the allotted resources? A (very) rough comparison: the hsqldb main-memory Java RDBMS can run jTPCC an order of magnitude faster than mysql. I know hsqldb lacks durability, but only a WAL would be needed, which (with group commits) is characterized by largely sequential writes. Ideally, I can bring mysql to this point -- the database is stored in memory, with only a WAL producing sequential writes to disk, as opposed to incurring random seeks due to buffer page flushes. OTOH, it may be possible that the DB is already entirely in memory, and the performance difference is due entirely to mysql runtime overheads. Either way, explanations/hints would be much appreciated.
