I can't find file mysqld.sym.gz!
hello~
When I try to Using a stack trace there's no mysqld.sym.gz on our
server . Can we always find mysqld.sym.gz on any operating system? Our
operating system is Linux 7.0 . I would like to mail you our error log to
see if you can tell us what's wrong with our MySQL which always crash
unexpectedly . Thanks !

There is a limit on the size of these tables. You can force MySQL to use a file in its temporary directory to store the results: set SQL_BIG_TABLES = 1; An alternative is to do a SELECT SQL_BIG_RESULT ... instead of SELECT ... . Note that SELECT SQL_BIG_RESULT doesn't work in 3.22.x, though it is accepted by the parser. You don't mention which version you use. 'set SQL_BIG_TABLES' works fine in 3.22.x. Note that if I'm correct, you're using a very old version of MySQL. You might consider an upgrade.

While executing a query, Got error 22275 from table handler
Description: When i execute the following query on my database: SELECT retaillastdone_.* FROM retaillastdone_ WHERE (retaillastdone_.source_=mercury AND retaillastdone_.timestamp_ BETWEEN 97864920 AND 978735599099) ORDER BY retaillastdone_.owner_,retaillastdone_.timestamp_ ASC ; I get the error ERROR 1030: Got error 22275 from table handler however, I am sure my tables arent corrupted as I ran myisamchk on it. The interesting thing is that the following query executes without any problems SELECT retaillastdone_.* FROM retaillastdone_ WHERE (retaillastdone_.source_=mercury AND retaillastdone_.timestamp_ BETWEEN 97864920 AND 978735599099) ORDER BY retaillastdone_.owner_,retaillastdone_.timestamp_ ASC limit 10; I used the email-support and got a reply from Sergei that its bug. Thus, Iam sending this testcase. How-To-Repeat: I am attaching the table retaillastdone with the bug. If you run the same query, that gives problems to me, the bug can be reproduced. Fix: Appened limit 10 at the end of the query as I did above, it will work fine. Submitter-Id: maarten4688 Originator:maarten4688 Organization: IMC.

consistency of NOW() function, and summary caching
I'm curious about what guarantees MySQL (and the SQL standard) provide with regard to multiple calls to NOW() within the same statement. If the statement takes a long time to execute, will NOW() be consistent across all invocations? The trivial example of this is if you're updating a large set of rows to an expression involving NOW(), but I'm more interested in INSERT and SELECT semantics. A simplified version of a more subtle example is: INSERT INTO order_sums (start_date, end_date, total) SELECT [literal date], NOW(), SUM(order_amount) FROM orders WHERE date_of_order = [literal date] and date_of_order NOW() The idea is that you've got an 'orders' table that gets a large amount of traffic- presumably thousands of delayed INSERT statements per hour- and users sometimes want to view a summary of the table. Instead of summarizing a huge number of rows every time, you keep caches of the summary info in another table. You'd lock the order_sums table, find the largest end_date, perform the above statement with the end_date substituted for [literal date], unlock the table, and then summarize the order_sums table. There are a couple of places that inconsistent NOW() values could cause erroneous results and an inconsistent database. First, the final 'date_of_order NOW()' is explicitly coded as a less-than and not a less-than-or-equal-to because there will very likely be additional insertions run before the end of the current second, so we leave the interval open at the top to ignore the current (partial) second. Does this in fact do what I want in the presence of many statements of the form INSERT DELAYED INTO orders (date_of_order, order_amount) values(NOW(),'123') or must I offset the NOW() by something safe like a minute to ignore inserts that haven't quite made it in yet? Second, it is obviously quite important that the NOW() in the select list exactly match the NOW() in the WHERE clause, since the next summary cache entry will be computed using its value. Is this guaranteed? Is it possible (and efficient) to alias the NOW() column in the SELECT list for use in the WHERE clause? How would that work? I'd also love any suggestions/criticisms of the above architecture. I'm trying to address what is a potentially significant performance issue for us (we hope to allow the main table to grow to tens to hundreds of millions of rows before pruning it down), but there might be a much simpler way to approach the problem. Experiences implementing solutions to similar problems would be much appreciated. - 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?

Mysql performance question
Hi people, May be anybody can advice from the personal experience tweeking which options both in the mysql configuration and server hardware can help in increasing mysql performance speed? As it is now, mysql is configured to occupy about 600M RAM, and queries per second avg goes up to about 100, yet under the top load it seems to be not enough. Here are the config options: set-variable= key_buffer=512M set-variable= max_allowed_packet=1M set-variable= table_cache=512 set-variable= sort_buffer=8M set-variable= record_buffer=1M set-variable= myisam_sort_buffer_size=64M set-variable= thread_cache=16 set-variable= max_write_lock_count=10 set-variable= thread_concurrency=8 The server itself is 2x PIII Intel Xeon 700 MHz, Intel KOA4 platform, with 4G RAM. Mysql 3.23.47 (binary distribution), FreeBSD 4.5 system. All mysql queries are rewritten so the INSERT/UPDATE's has been reduced or replaced by DELAYED as much as possible, to ease mysql locking. The mysql tables are indexed, all documentation from the main mysql site having been studied. And under the top load the mysql starts locking anyways. So what can be the best ways of helping it: - Changing mysql options, may be increasing key_buffer some more or what else? - Adding 2 more CPU's to the server (it can bear up to 4 CPU); - May be there can be some other ways?

Here are the config options: set-variable= key_buffer=512M set-variable= max_allowed_packet=1M set-variable= table_cache=512 set-variable= sort_buffer=8M set-variable= record_buffer=1M set-variable= myisam_sort_buffer_size=64M set-variable= thread_cache=16 set-variable= max_write_lock_count=10 set-variable= thread_concurrency=8 The server itself is 2x PIII Intel Xeon 700 MHz, Intel KOA4 platform, with 4G RAM. Mysql 3.23.47 (binary distribution), FreeBSD 4.5 system. All mysql queries are rewritten so the INSERT/UPDATE's has been reduced or replaced by DELAYED as much as possible, to ease mysql locking. The mysql tables are indexed, all documentation from the main mysql site having been studied. And under the top load the mysql starts locking anyways. So what can be the best ways of helping it: - Changing mysql options, may be increasing key_buffer some more or what else? - Adding 2 more CPU's to the server (it can bear up to 4 CPU); - May be there can be some other ways?

Error 1058 Win2K Server with MySQL
We are trying to install MySQL on a Windows 2000 Server, but are getting 'error 1058' when we try to start the service. The MySQL version is 3.23.47-nt. The MySQL drive is F:, and c:\my.cnf is: [mysqld] port=3306 big-tables skip-locking set-variable = key_buffer=16M set-variable = max_allowed_packet=1M set-variable = thread_stack=128K set-variable = flush_time=1800 set-variable = lower_case_table_names=1 basedir = F:/MYSQL/ console [mysqldump] quick set-variable = max_allowed_packet=16M [MYSQL] no-auto-rehash [isamchk] set-variable= KEY=16M [client_fltk] help_file= F:\MYSQL\sql_client\MYSQL.help client_file= F:\MYSQL\MYSQL.options history_length=20 database = Wires queries_root= F:\MYSQL\queries last_database_file= F:\MYSQL\lastdb This system is to use MyISAM tables. From a DOS prompt, we switched into the F:\MYSQL\BIN directory and... mysqld-nt --install Win2K reports the service installed. When we ... net start mysql we get the following error: System error 1058 has occurred. The service cannot be started, either because it is disabled or because it has no enabled devices associated with it. Anyone had this problem ... found a fix ... have any idea what is wrong???

Re: Mysql performance question
Hi Simon, A couple of things, unless you have compiled WITH_LINUX_THREADS from the /usr/ports/databases then adding more processors will be unlikely to help. The native threads lib on FreeBSD runs a threaded app on 1 processor currently, use the LINUX_THREADS option in the ports to get around this if you would like to add more processors. Do you have softupdates on also? Have you read 'man tuning'? Are you accessing alot of tables/DBs? If yes what is your table_cache value? What is in 'SHOW STATUS' and 'SHOW VARIABLES'? Also MySQL 4.0.1 has a query cache that is incredible! It works great. 6000 queries per minute is pretty good performance. Have you looked at using heap tables where possible? Another suggestion if everything is hitting the same table/database have you tried innodb tables? They work very well under high loads. I would study all the 'SHOW STATUS' output and see if you can spot anything in the manual page for each of the variables.

You might want to GROUP BY a different column, e.g. 'typ' or 'marke' in your example.

[SECURITY] How do these blank passwords get into mysql.user?
One thing's been bothering me for a while: When I create a user and
database in MySQL, the user always ends up with an extra entry with
host='%' and password=''. How is this happening? This is how I create
a new database and user:
mysql create database xxx;
Query OK, 1 row affected (0.01 sec)
mysql insert into user set host='localhost', user='xxx', password=password('yyy');
Query OK, 1 row affected (0.03 sec)
mysql flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql grant all privileges on xxx to xxx;
Query OK, 0 rows affected (0.03 sec)
mysql grant all privileges on xxx.* to xxx;
Query OK, 0 rows affected (0.00 sec)
mysql flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql select host,user,password from user where user='xxx';
+---+--+--+
| host | user | password |
+---+--+--+
| % | xxx | |
| localhost | xxx | 66debff13dff1053 |
+---+--+--+
2 rows in set (0.00 sec)
What did I do wrong to cause these users with blank passwords to be
created (essentially opening me wide to the outside)? My MySQL version
is 3.23.47. It's worked fine after I delete the extra row in the user
table manually, but this could be dangerous to someone who doesn't
notice it!

Re: [SECURITY] How do these blank passwords get into mysql.user?
Philip,
you should explicitly specify host/password in the GRANT statement, like
this:
GRANT ALL ON xxx.* TO user@'localhost' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
This way the user will only granted access from the specified host, you
don't need to manually INSERT into the user table. (You'll also get rid
of the empty passwords.)

is 3.23.47. It's worked fine after I delete the extra row in the user
table manually, but this could be dangerous to someone who doesn't
notice it!

Re: [SECURITY] How do these blank passwords get into mysql.user?

Hmm, I just ran another experiment: mysql create database xxx; Query OK, 1 row affected (0.00 sec) mysql grant all on xxx to xxx; Query OK, 0 rows affected (0.00 sec) mysql select host,user,password from user where user='xxx'; +--+--+--+ | host | user | password | +--+--+--+ | %| xxx | | +--+--+--+ 1 row in set (0.00 sec) So if I execute a GRANT statement without specifying a password, and MySQL decides that it needs to create a new user for this (host,user) pair, then it will create it with blank password! This seems to be insecure default behavior to me. I wonder if it would be better to change MySQL such that it will not create a user with blank password like this unless IDENTIFIED BY '' is explicitly specified? - 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: another xml thread

But that doesn't touch major possibilities of XML. If you want to take data from XML documents and store them within MySQL, I see no way how that can be done reasonably. I see. I had not considered how more complex (and more tree-like) XML documents would be handled by the RDBMS. I was thinking about my particular application, which is actually very simple, and would rely only on a single table (each column of the table would contain the content of a separate element in the XML file). But now that I think about it, this is much more simple than some XML files will end up being, given their hierarchical structure. So perhaps it's fine for my basic purposes, but not the best solution for complex XML documents. IIRC, the thread you cite was so long, because some (one?) of the people partiating did not know what they were talking, but kept insisting on their point. But I did not have a second look, so I am not sure if I am mis-remembering. Yes, there was a lot of back-and-forthing. Thanks, Erik Erik Price Web Developer Temp Media Lab, H.H.

RE: get instance variable
Hi Robert - The only way I have found to get this sort of stuff (as well as security info) out is to use mysql_query (or mysql_real_query) and issue the query just like you would at the mysql client. Then you can interpret the results that are returned. I am having to do that with column level grants by user ID to implement views of the data in a C++ environment and it's the only way that I could find to do it. There are not a lot of C API things that are specific to getting data column metadata and other configuration data. IT is mostly for obtaining connections, results sets, and manipulating result sets. It appears that the way they want you to get stuff out using the C API is not with lots of specific calls, but by just issuing the command yourself and interpreting the result set. I found the best way is to write a simple program to issue a call and the cout the result set information. Be sure and do that because sometimes the returned data will surprise you a little bit I have some working C++ connection and result set classes if you would like them, plus a test program you can use.

Re: Mysql performance question
Thanks a lot for the advices. The value for table_cache is 8572, and I'm indeed accessing a lot of tables. So as I gather it the main effect should be expected from transfering to MySQL 4.0.1 compiled with LINUX_THREADS and using innodb tables, true? Now what can you say about reliability issue, aren't these products currently in the development stage and can they be used for the production server?

The native threads lib on FreeBSD runs a threaded app on 1 processor currently, use the LINUX_THREADS option in the ports to get around this if you would like to add more processors. Do you have softupdates on also? Have you read 'man tuning'? Are you accessing alot of tables/DBs? If yes what is your table_cache value? What is in 'SHOW STATUS' and 'SHOW VARIABLES'? Also MySQL 4.0.1 has a query cache that is incredible! It works great. 6000 queries per minute is pretty good performance. Have you looked at using heap tables where possible? Another suggestion if everything is hitting the same table/database have you tried innodb tables? They work very well under high loads. I would study all the 'SHOW STATUS' output and see if you can spot anything in the manual page for each of the variables.

HTML dumping into browser...
I am having trouble convincing my SQL admin at the hosting company that something is wrong with the server / speed. It is really odd, but in myPhpAdmin for example, on the left hand side the list of databases comes out properly for about 95% of the list, then it starts dumping HTML into the frame. I thought this was just poor coding and a burp / hiccup, however, when the tech tried to perform the same functions in Vancouver, and also via a server in Florida, he did not have the problem. However, when tried from home on a DSL line, and from a phone line in rural Ontario(canada) not only the PHPadmin is farting, but some of my code as well Has anyone experienced this problem?

So now I use the sql-query : select min(preis),lfd from database where marke='marke' and typ not like 'R%' and typ not like 'X%' and typ not like 'C%' group by preis, lfd; (this gives me several lines ordered, so the min(preis),lfd is the first row) Oliver - 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?

!------ MySQL C API ----------!
I have a written a Windows client that accesses a MySQL server (Linux) via the MySQL C API. Stored in the MySQL database are large files (larger than a Mbyte). The C API makes it very easy for the client to query and alter the database. However, I have some special needs that don't appear to be addressed by the C API. The windows client needs the ability to download files from the database. But, before the files can be downloaded to the client, the server needs to insert (into the file) some custom information and then encrypt the entire file. Here are my questions: 1. Is there any way I can get MySQL (by means of the C API) to execute a custom process on certain entries in the database? 2. Once the custom processing has been accomplished, how can I transfer the customized file from the server to the client? 3. Apache is not part of the equation, but I would love to use PHP to solve the above problems. Is there any way that this could be accomplished? Thanks in advance for any advice that you might have.

Re: [SECURITY] How do these blank passwords get into mysql.user?
»Philip Mak« sagte am 2002-02-19 um 10:25:38 -0500 :
One thing's been bothering me for a while: When I create a user and
database in MySQL, the user always ends up with an extra entry with
host='%' and password=''. How is this happening? This is how I create
a new database and user:
mysql create database xxx;
Query OK, 1 row affected (0.01 sec)
mysql insert into user set host='localhost', user='xxx', password=password('yyy');
Here you set that the user xxx has the password yyy.
mysql grant all privileges on xxx.* to xxx;
Here you insert another user but don't set a password!
BTW: You don't have to insert the user manually. If you try to GRANT
access to a non existing user, the user will be silently created.

v3.22.32 and temp tables
Hi, I want to build a temp table which I can query to sum values. If I try create temporary table tbl_name select some_query_here, then I get an error that tells me that I have an error with my sql syntax near 'temporary table tbl_name select some_query_here'. Am I correct in thinking that this is due to the version of mysql I'm using? (No, I can't upgrade it at this point).

innodb table status : Why is Max_data_length NULL?
I have two InnoDB tables using a pool of space (the combined size of the data files may change). I want to limit each to using half the amount of space (or split it in some manner .. 60%/40%, etc). So far I've done this with a daemon that runs all the time deleting appropriate rows when the table nears capacity (I have it looking at the Data_length and Index_length columns of Show table status like 'tablename' and compairing the sum to the max that I've hardcoded).. But of course this requires that magic number in there. I'd like to be able to pull the max out of the database somehow, which brings me to my question.. Why is max_data_length null? And is there a way I can get to this value? Is there a better/different way to do this?

RE: basic query question

Re: Mysql performance question
Your welcome Alexander! OK the value for table_cache is 8572 * 3 = 25716 file descriptors, how big is kern.maxfiles and kern.maxfilesproc? These need to be set above 26000 to allow all those tables to be opened! I know I have missed this sometime, or not reset them after a kernel compile. Also you don't need 4.0.1 for innodb tables, they work fine on 3.23.49 and LINUX_THREADS option from the ports package I think is only available for 3.23.xx versions. The only problems I have had with 4.0.1 have been self inflicted. There are some bugs in some of the newer features, 4.0.2 should be out soon. I have been kicking around the idea of using 4.0.1 in production as none of the bugs so far really affect my application.

The native threads lib on FreeBSD runs a threaded app on 1 processor currently, use the LINUX_THREADS option in the ports to get around this if you would like to add more processors. Do you have softupdates on also? Have you read 'man tuning'? Are you accessing alot of tables/DBs? If yes what is your table_cache value? What is in 'SHOW STATUS' and 'SHOW VARIABLES'? Also MySQL 4.0.1 has a query cache that is incredible! It works great. 6000 queries per minute is pretty good performance. Have you looked at using heap tables where possible? Another suggestion if everything is hitting the same table/database have you tried innodb tables? They work very well under high loads. I would study all the 'SHOW STATUS' output and see if you can spot anything in the manual page for each of the variables.

Re: row level privilages - thoughts on how to do
Hi Noel, On Tue, 2002-02-19 at 13:40, [EMAIL PROTECTED] wrote: I'm wondering about row level privilages - being able to restrict what people see and can update etc on a row level as well as a column/table level. As others mentioned, having VIEWs wouldn't necessarily be of any help, since VIEWs are quite restrictive about INSERT/UPDATE type operations on the view. Anyway, after a little pondering, I think I've come up with a fairly nice solution for this problem. It is MySQL specific though: Use MyISAM MERGE tables (http://www.mysql.com/doc/M/E/MERGE.html). You can define a MERGE table, merging multiple *identical* MyISAM type tables. It is a bit like a view, in a way. You can do a query on the merge table, which will internally gather data from all the tables. How does this help you? You set up your permissions so that admin tools have full access to the merge table and all its parts. For individual users, you only grant access to their own table, to the extent that you want. Some shuffling between tables might be required when a row is for instance 'transfered' to another user, but I would figure that that is fairly easy to handle. Anyway, this way the plain end-user application can be bound by the user permissions, there's nothing specific the application needs to do, and no way for the user to circumvent that system. This may not be suitable for every situation, but it might be useful here Regards, Arjen. -- Get MySQL Training Worldwide, http://www.mysql.com/training/ __ ___ ___ __ / |/ /_ __/ __/ __ \/ /Mr. Arjen G.

Again, a speed increase and/or compiled code decrease if that is selected. instead gcc to compile mysql. But it doesnot accept these three flags. I'm curious... what are you using?

Re: -fno-implicit-templates, -fno-exceptions,-fno-rtti problems
Thanks for your reply. But You can find something from http://www.mysql.com/doc/I/B/IBM-AIX.html : If you are using gcc or egcs to compile MySQL, you must use the -fno-exceptions flag, as the exception handling in gcc/egcs is not thread safe!

RE: **Backing Up A Database**
Hi Felix (or anyone),
I'm giving this a go but as a Linux newbie running Red hat 7.2 I have a
question to ask
Do I need to alter anything in Cron for it to run the logrotate script?
What would I need to put into the hourly cron folder to make things happen
more often to check they are working correctly?

- create a file in /etc/logrotate.d, filename does not matter, take
this as a template, fill in connection parameters in mysqldump call
():
/home/backup/sqlback/mybackup.sql {
daily
nomissingok
nocreate
compress
rotate 14
errors [EMAIL PROTECTED]
prerotate
mysqldump --opt --full
/home/backup/sqlback/mybackup.sql

}
- check syntax and options of this file: man logrotate
- you're set: cron will call logrotate each night. logrotate
processes each file in the dir, executes the prerotate script and
then compresses the logfile (i.e. SQL-Dump), renames older ones
and keeps at max 14 of them (rotate 14). nomissingok will let
you know if the mysqldump failed

security concerns and 1044 access denied problem
Hi gurus, Here's my problem: After installing binary version of mysql on sun, I try to add a new user and a new database, namely `dbuser' and `mydb', such that dbuser can access mydb but nothing else. However I found that if I do not grant dbuser 'select' privilege in mysql.user, dbuser cannot connect even if dbuser is granted select privilege for mydb in mysql.db. (1044 error) After granting dbuser 'select' privilege in mysql.user, dbuser can connect to mydb but then dbuser can connect to the database called 'mysql' as well, and thus read mysql.user. Now dbuser knows more than he needs, which is a security concern for me. So is there a way to both be secure and still allow a user to connect?

Question on maximum record input frequency and table lengths.
Hello, We are considering using MySQL in an application involving recording and processing analog signal inputs from various electric powerplant instrumentation. Some (but not a majority) of these signals will take and need to record and discrete measurements at a frequency from 360 to 1000 or so times per second. These measurements will be subject to relatively simple queries (greater than or less than comparisons and conditional statements) As each instrument monitored will be providing a distinct piece of data on a separate analog channel, and will not by precisely synchronous with output from other analog channels, our initial idea is to have each analog channel output to a separate table in the database. On the largest plants we would expect to monitor, we would have about 42 separate analog channels (tables) taking data at the 360 or more times per second. Each of these tables would have two fields - a record number (index) autoincrementing, and a numeric (probably a smallint in most cases) which are change, and a couple of static identifier fields, so each record would be on the order of 100 bytes or less. Assuming there are no hardware constraints (everything would be on dedicated servers, with whatever hardware is necessary) are there any known limits on how many tables/records the MySQL database engine can handle? Most of this data would be disposed of (reduced to one record per second) after 24 hours, if no plant alarm conditions have occurred in that 24 hour period, so permanent storage of huge tables isn't an issue - but at 360 x 86400 seconds per day, there would still be several million records in these tables - is there any means of estimating the impact this would have on the number of records and tables which could be successfully written in this scenario? Thank you for any help you are able to give, or any resources you can point us to.

Interesting application! It is always nice to hear where MySQL is being used Assuming there are no hardware constraints (everything would be on dedicated servers, with whatever hardware is necessary) are there any known limits on how many tables/records the MySQL database engine can handle? The limits are known, see http://www.mysql.com/doc/T/a/Table_size.html As you will see, provided you are using a recent version of MySQL Server, the only possible issues stem from operating system limitations. So that is something to keep an eye on when building your servers and choosing an operating system. Linux and Solaris are the most used and generally give the best performance, but FreeBSD (latest version) is also popular. Most of this data would be disposed of (reduced to one record per second) after 24 hours, if no plant alarm conditions have occurred in that 24 hour period, so permanent storage of huge tables isn't an issue - but at 360 x 86400 seconds per day, there would still be several million records in these tables - is there any means of estimating the impact this would have on the number of records and tables which could be successfully written in this scenario? This type of application and size should not be a problem, MySQL is used quite often in high volume logging. MySQL also offers specific features such as MERGE tables that allow you to operate on large sets of (historical) data. Older tables may even be compressed (and archived on CD) while still being read-only accessible, and be fully combined (by the server) with the latest online data. Optionally, the system collecting the latest data could be separated from the system that deals with the older aggregate information. Thank you for any help you are able to give, or any resources you can point us to. I hope the above will give you some basic idea of what is possible. For more detailed questions, you may wish to contact [EMAIL PROTECTED] Another option could be MySQL training (http://ww.mysql.com/training/); the courses spend considerable time on optimisation of the operating system and MySQL Server configuration, database design and queries.

Please, need help urgently
I need some help, this is a mission critical server and it has CRASHED! Details:FreeBSD on INTEL, MySQL v3.23.36 (FreeBSD Port) The server had to be rebooted, and when it came back up, my MySQL server died.

Re: Please, need help urgently
Hi, It would be time consuming to understand why the server crashed and then repair the server, as u say it is a mission crtical one , the quickest way to get it up and running would be to back up the database (copy the ur database directory completely under the data directory) reinstall MySQL cleanly and get the DB back in action again.Also make sure u've got a 'release' build of MySQL, I got the following info from a site hope that helps.. Signal 11 Description : Signal 11, or officially know as segmentation fault, means that the program accessed a memory location that was not assigned. That's usually a bug in the program. So if you're writing your own program, that's the most likely cause. However, this FAQ will concentrate on the possibilities besides that. The cause can be software or (most likely) hardware for a Signal 11 crash. Read on to find out more. (*) Of course nothing is Linux specific. If your hardware is flaky, Linux, Windows 3.1, FreeBSD, Windows NT and NextStep will all crash. If you are not reading this at http://www.BitWizard.nl/sig11/, that's where you can find the most recent version. cheers, Sundara Pandian, Megasoft Ltd, India. - Original Message - From: SplitSlim [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, February 20, 2002 10:14 AM Subject: Please, need help urgently I need some help, this is a mission critical server and it has CRASHED!

Hi! I believe NuSphere does not distribute MySQL-Max-3.23. Tergat MySQL Studio contains MySQL-Max-3.23.47. Do you literally need an 'off-the-shelf' product?
