What does optimize mean?
Seeing posts about mysqlcheck on the list prompted me to check out that utility. A lot of it I can see is very useful, and I understand what it does. However, what does the optimize command mean? What does it do? The help file says that the -o option optimizes, but what does that mean?? I ran it on one of my databases, and most of them said OK, and some of them said table is already up to date. But I still have no idea what it did, if anything.

OK, I missed it this time because I partially typed in something when searching for this in the manual.

SHOW PROCESSLIST State Locked - what does this mean?
Hi, Currently, I have a situation where an app makes connections (via JDBC) to a mysql server, 50 connections at once, and everything just becomes super-slow. For instance, a SELECT that should take 0.01 sec takes several minutes. SHOW PROCESSLIST says that these threads that are connections from the app are in a state Locked. The mysql manual doesn't explain this option, or even list it as a possibility (maybe I'm looking at the wrong place: http://dev.mysql.com/doc/mysql/en/SHOW_PROCESSLIST.html) The other question is what one can do about this, to prevent this locking, or even diagnose it. Thanks for your help. Jim -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

OK I got the database created and stuff; When in the MySQLAdmin screen under databases it doesn't show under databases. That is the first problem.

But I can get into the mysql shell and see the database I created and I did the GRANT ALL ON MariluMessageBoards.* TO [EMAIL PROTECTED]; I also try the MySqlCC and try to get on the server and it won't let me.

Did you set a password for the root account? MySQL comes with a root user that (initially) has no password and all privileges. Most setup instructions have you assign a password to the root account pretty early on. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

The above is a very strange error; Basicly something that should never happen. It means that somehow you have more threads wanting to request for a alarm (used to timeout connections) than was registered when mysqld started. This should be impossible as we init the alarms with the following code in mysqld.cc init_thr_alarm(max_connections+max_insert_delayed_threads) In other words, we reserve as many alarms as we can have connections + insert delay threads; As a thread can only have one alarm and and no other threads than a connection or insert delay thread uses alarms I can't understand how you can get this error. Note that even if the alarm call fails, mysqld will work normally with the exception that a long lived connection will not time out. If you cando a new bug report, preferably with the 'mysqlbug' script, that includes the following information, I could try to dig deeper into this problem.

Re: What does this mean? : Warning: thr_alarm queue is full
Chung, Warning: thr_alarm queue is full What's this? Is it serious problem? Looking for thr_alarm in the MySQL Manual, I find this: If mysqld is compiled with -DUSE_ALARM_THREAD, a dedicated thread that handles alarms is created. This is only used on some systems where there are problems with sigwait() or if one wants to use the thr_alarm() code in ones application without a dedicated signal handling thread.

what does it mean Open_files?
Hi, after some testing on a new db, I have this status: [root@rachab /root]# mysqladmin e | grep "onn\|pen.*es" | Aborted_connects | 12 | | Connections | 150194 | | Max_used_connections | 24 | | Open_tables | 0 | | Open_files | 7909 | | Opened_tables| 222981 | | Slave_open_temp_tables | 0 | | Threads_connected| 1 | Option open-files-limit is set to 8192. But why Open_files is 7909 when Open_tables is 0 and only one connection (own mysqladmin) is estabilished? Is there any relation in Open_files, Open_tables and Threads_connected? Manual says yes, but these numbers doesn't agree with. Could it rather be Opened_files than Open_files?

ERROR 2002: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) and how you fix it? It means you have no local socket for mysql to connect through. Meaning, something/someone either deleted or mangled /tmp/mysql.sock or mysqld isn't running to begin with. Try to connect with the -host flag to connect (so it won't use the socket) and shutdown and try to restart the mysqld - hopefully this will recreate mysql.sock Take care, seth --- Seth Northrop Manager of Information Technology Reflectivity, Inc. 3910 Freedom Circle, Suite 103 Santa Clara, CA 95054 voice: 408-970-8881 x147 fax:408-970-8840 http://www.reflectivity.com/ - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

I don't have Charles first message on this topic, but I believe his error message was from logrotate which is a cron job. If Charles put mysqladmin -uuser -ppassword into a cron job, then the user's(root?) password would be in open view to anybody who could view the crontab - granted, you would have to be root to view the root crontab, but putting the password to the MySQL user right in the cron command is just a little too "loose" for me. A safer method would be to "hide" the user/pw in the Unix user's home directory in the ..my.cnf file, as I outlined below. Uh... root can read those too. If you're imagining a situation where someone just rooted you in order to get access to MySQL, I guess it's possible that doing it this way will slow him down by about 5 minutes, but I don't really think it's an issue. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: [PHP] What Does This Mean?
I am not very sure of what exactly does this this mean but I guess that the particular module that you are installing requires a cversion of PHP that has to be greater than 3.0.8.

RE: What does this mean ?
This patch will make it into 4.0.5, I believe. 4.0.4pl1 fixes only two bugs
(one security issue, and one that make the PDF plugin work again).
My patches could have side effects, since it will run code that has never
been run before (like actually closing those persistent connections). They
are in CVS.
If you are using Apache (most of us are with PHP), note that persistent
connections are per process, not per machine. Mod_ssl can use an Apache
extension to keep shared memory across processes, but PHP does not. Read the
docs (or the PHP list) to find out more.
Sincerely,

That is what I suspected. I suffer the same.
The problem is buggy PHP persistent connection code. The "almost good"
solution was presented to PHP people by Steven Roussey
(http://marc.theaimsgroup.com/?l=php-devm=97562841130973w=2) and
(http://marc.theaimsgroup.com/?l=php-devm=97858730928909w=2)
and according
to Andi Gutmans
(http://marc.theaimsgroup.com/?l=php-devm=97858932431876w=2)
the patch was
committed to PHP CVS.
However the patch is absent even from PHP 4.0.4pl1 (its
zend_list.c is dated
2000-10-20). You might try to patch your PHP by yourself. Or try
the latest
snapshot from http://snaps.php.net (though I don't know if the patch is
there).
Sincerely speaking I don't know why Steven's patches haven't been
incorporated into PHP 4.0.4pl1. Maybe Andi (Cc:ed) could explain this?

I use php 4.0.3 with persistent connections. MySQL is installed on Linux
RedHat 7.0.
The problem is that the Mysql exists and I don't know exactly
what appends
to the php process

From when I installed the mysql 3.23.30gamma I have mysql
reporting these
warnings:
10115 17:51:22 Aborted connection 2886 to db: 'db_name' user:
'user' host:
`www.host'
(Got an error reading communication packets)
010115 17:51:36 Aborted connection 3754 to db: 'db_name'
user: 'user'
host: `www.host'
(Got an error reading communication packets)
We have 700-800 contemporary connections to mysql and these
warnings are
given periodically every 5-10 minutes...
Why does Mysql generate these logs?

mysql_pconnect still broken (was: RE: What does this mean ?)
OK. Look at a quick report. I've just installed php4-200101152345. It runs with mysql-3.23.27-beta. Apache 1.3.12, Solaris 2.6 (local host) and 2.4 (remote connection). What I can see is: the offending messages didn't vanish at all (both hosts are involved): 010116 20:52:30 Aborted connection 36021 to db: '***' user: '***' host: `***' (Got an error reading communication packets) So, I think it's not fixed yet. Steven, you wrote about 99,8. I suppose every Apache process here makes this error while ending. I just see it. Steven, thank you for your efforts. Hope you can fix even that. Please let me know about patches: I'll happily test them. I'm not able to fix it by myself, but I'd like at least be helpful.

:)
Andi, I hope you are reading this.
I looked at the CVS, and my patch was not properly applied. Andi has it
looking through the non-persistant destructors, rather than the persistent
ones (meaning that plist_entry_destructor is identical to
list_entry_destructor).
In file zend_list.c replace the plist_entry_destructor definition with:
void plist_entry_destructor(void *ptr)
{
zend_rsrc_list_entry *le = (zend_rsrc_list_entry *) ptr;
zend_rsrc_list_dtors_entry *ld;
if (zend_hash_index_find(list_destructors, le-type,(void **)
ld)==SUCCESS) {
switch (ld-type) {
case ZEND_RESOURCE_LIST_TYPE_STD:
if (ld-plist_dtor) {
(ld-plist_dtor)(le-ptr);
}
break;
case ZEND_RESOURCE_LIST_TYPE_EX:
if (ld-plist_dtor_ex) {
ld-plist_dtor_ex(le);
}
break;
EMPTY_SWITCH_DEFAULT_CASE()
}
} else {
zend_error(E_WARNING,"Unknown persistent list entry type in
module shutdown (%d)",le-type);
}
}
