Upgrade from MySQL 3.23.x to MySQL 4.1.x [InnoDB question]
Hi all, A little question... Can I upgrade directly a server with MySQL 3.23.x version which has some MyISAM databases (no problem with it) and some InnoDB databases towards MySQL 4.1.x? Or have I to do a dump and restore instead of re-use databases? wdyt? -- Cedric Gavage - [EMAIL PROTECTED] - OpenPGP: 0xED325C64 -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
MyISAM
Hi all, I have a question about MyISAM, during an UPDATE for a row, is it a row locking or a table locking? -- Cedric Gavage [EMAIL PROTECTED] http://unixtech.be - http://gavage.com - OpenPGP: 0xED325C64 -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
tuning problem or bug?
Hi all, I have a question about a mysql server under Debian GNU/Linux. debian version: woody mysql version: 3.23.49-8.2 libc6 version: 2.2.5-11.2 kernel: 2.4.20 CPU: bi-P3-1266 (Compaq Server proliant) Memory: 2 Go I have often the error message Can't create a new thread (errno 11). If you are not out of available memory, you can consult the manual for a possible OS-dependent bug. Then I recompiled the libc6 package with these changes (debian use softs with shared libraries): in linuxthreads/internals.h: #define STACK_SIZE (2 * 128 * 1024) in linuxthreads/sysdeps/unix/sysv/linux/bits/local_lim.h: #define PTHREAD_THREADS_MAX 4096 in /etc/sysctl.conf: fs/file-max=65536 in /etc/mysql/my.cnf: [safe_mysqld] err-log = /var/log/mysql/mysql.err open-files-limit = 8192 [mysqld] user= mysql pid-file= /var/run/mysqld/mysqld.pid socket = /var/run/mysqld/mysqld.sock port= 3306 basedir = /usr datadir = /var/mysql/data tmpdir = /tmp language= /usr/share/mysql/english skip-locking set-variable= key_buffer=128M set-variable= max_allowed_packet=4M set-variable= table_cache=512 set-variable= sort_buffer=2M set-variable= record_buffer=2M set-variable= thread_cache=8 set-variable= thread_stack=128K set-variable= max_connections=500 set-variable= max_connect_errors=100 set-variable= wait_timeout=1 # Try number of CPU's*2 for thread_concurrency set-variable= thread_concurrency=4 set-variable= myisam_sort_buffer_size=64M I receive the error message when I have more than 255 threads at the same moment (mytop report). May be the kernel to tune?

SMP on Sparc/Solaris7
Hi all, Is there someone which use mysql-3.22.* or mysql-3.23.* on a UltraSparc bi cpu with Solaris7? In my case, mysqld (with all its threads ;)) is always on one cpu... the second is never used...
