ISAMCHK utility - MySQL server - 3.21.33b
Hello: Can anybody help me out to repair my database & tables using ISAMCHK utility. The MySQL server version is 3.21.33b installed on BSD server. Many thanks Sheni Details of the problem that we are facing now: We are facing a serious problem with the MySQL server installed on our web server (BSD/OS). The server was working fine till last week. Since then it started crashing. It crashes 2-3 times a day. Every time we have to kill the process and restart the server (UNIX). Not only the MySQL server the entire server crashes because of the load on the CPU. ###CPU STATE### load averages: 1.00, 1.00, 0.92 02:47:57 278 processes: 13 running, 265 sleeping CPU states: 0.0% user, 98.4% nice, 1.6% system, 0.0% interrupt, 0.0% idle Memory: Real: 40M/94M Virt: 217M/1481M Free: 342M PID PRI NICE SIZE RESSTATE TIME WCPU CPUCOMMAND 270 94 44420K 2024K run43:48 97.17% 97.17% mysqld ## The MySQL version is 3.21.33b .

RENAME TABLE and locking
I'm using MySQL-3.23.49a I use MySQL to replace plain text log files. The logging happens in a table named "current". Every midnight, at 00:00:00, i perform a table rotation with this command from a cron job: CREATE TABLE new RENAME TABLE current TO $date, new TO current where $date is yesterday's date. The problem is, it's impossible to prevent today's messages from creeping into the old, rotated table. The reason is, there's always a very short delay before the rotation is performed, and some of today's messages always get into "current" before rotating it. I wonder if i can use locking to correct this problem. I mean: i create table "new", lock it, perform the rotation (so now "new" is "current", while the old "current" is "$date"), flush today's record from "$date" into "current", then unlock "current". Will it work this way? I'm not sure what happens to locking after RENAME; if i lock "new" and RENAME it to "current", will the lock be inherited by "current"? -- Florin Andrei You know you're in trouble when packet floods are competing to flood you. - 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: Databases with Tables approaching several million

I was told that > mysql was optomized to be fast, and would not be able to handle databases > of large sizes and I'm just wondering if this is largely true or not. The latter is not correct. MySQL is indeed designed to be fast, but MySQL is also fully capable of handling large databases. One does not preclude the other. The issue is simply that for small databases, OS and server tuning, proper table and application design, are often regarded as less important since the system will be fast enough anyway. Naturally, as a database grows, these issues do become more important. Clearly, throwing more hardware (or different RDBMS software) at the problem is not the real solution. It merely evades the aforementioned issues of tuning and design. The MySQL manual (http://www.mysql.com/doc/) contains some good pointers on OS and server tuning, table design and query optimisation. There are also good books on the subject. Some design methods are relevant for all RDBMS, some are specific to MySQL and/or your particular application. In addition, MySQL AB provides services such as training (http://www.mysql.com/training/) where these things as well as other fundamentals are extensively covered, and of course consulting (http://www.mysql.com/consulting/). Generally speaking, nothing beats experience (backed up with training). In situations where you don't have enough time to gain the necessary experience yourself, consulting might be a better short-term option since it acquires the experience externally. Training is still recommended though, since it is always best if you are (in the future) able to help yourself. To return to your question, there are MySQL users that have many times more rows in their databases than the numbers you mention. Some of these you will find as Success Stories on the MySQL website (http://www.mysql.com/), and perhaps others will write their own reply here. In any case, running a database of this size with MySQL is not a problem.

Re: how to turn off query logging in mysql, redhat linux
it was started when machine was started
check /etc/rc.d
and in mysql manual 2.1.1
if u don't need it now, just stop the server
and start it like "./bin/safe_mysqld &"
but u have to modify rc.d anyway for next time your server start
dont log anymore.

how to turn off query logging in mysql, redhat linux
Hello
I am trying to turn off the query log in mysql on redhat linux. It generates
huge log files (in /var/lib/mysql/hostname.log) that I dont need, and
impacts performance.
safe_mysqld was run with --log, and it seems like I want to turn that off
but I cant find any script or config file where the --log was specified,
perhaps it was compiled in?
I only have a binary distribution of mysql. Is there some way to override
the --log?
I have looked at section 4.9 of the mysql manual and
/etc/my.cnf (see below) and these scripts
/etc/rc.d/rc[0-6].d/K12mysqld
/etc/rc.d/init.d/mysqld
/usr/share/mysql/mysql.server
Does anyone know which of these scripts is really the one that starts
safe_mysql?
(note that the err-log setting in my.cnf refers to an error log (empty on my
machine) not
the query log that I am trying to get rid of.

how to turn off query logging for mysql on redhat linux
Hello
I am trying to turn off the query log in mysql on redhat linux. It generates
huge log files
(in /var/lib/mysql/hostname.log) that I dont need, and impacts performance.
safe_mysqld was run with --log, and it seems like I want to turn that off
but I cant find
any script or config file where the --log was specified, perhaps it was
compiled in?
I only have a binary distribution of mysql. Is there some way to override
the --log?
I have looked at section 4.9 of the mysql doc, and
/etc/my.cnf (see below) and these scripts
/etc/rc.d/rc[0-6].d/K12mysqld
/etc/rc.d/init.d/mysqld
/usr/share/mysql/mysql.server
Does anyone know which of these scripts is really the one that starts
safe_mysql?
(note that the err-log setting in my.cnf refers to an error log (empty on my
machine) not
the query log that I am trying to get rid of.
Please reply directly and to the list
-thanks Tom

Re: UTF-8 national characters
Sven Bentlage asked > Is there a way to get UTF-8 national characters sets working when you > only have user access to a database (it's my ISP's)? Whether you use the my.cnf/my.ini configuration file or the startup parameter, it's a startup option. You have to have access to one or the other. Maybe, if they are willing to provide mysql, they will also be willing to let you do some configuration. Only way to know is to ask your ISP. If they don't know, you might want to put a my.cnf in your home directory, just to see what happens. You'll need to check the manual. > (I know this is going to upset some people, but I do not have any time > left and RTFM won't help me right now..) Then check it later. > Can anyone of you send me a list/link to a list (or even better a > download location) of all available UTF-8 national character sets and a > small description on how to get them working as fast as possible? UTF-8 is not supported until 4.1 comes out. But if you don't need to sort or collate on those fields, just store it as blob and make your application remember that it's supposed to be UTF-8, and with a little work you should be okay.

Database size
I am new to MySQL to begin with. I am running syslog messages to a DB. It sends anywhere from 3500 to 5600 per minute. I then use PHP to look at the data. The DB machine is a Dual 1Ghz processor with 1Gb Ram. The problem is the speed of lookups. The DB has about 7 million rows and is continually growing. Should I break this up by the day to speed up searches? It takes about 2 minutes to do a search on the data. Just looking for pointers.

In my opinion, I believe what Codd is describing here is the ability to get to the DDL via the relational model, which MySQL does support. His notion of metadata is table names, column names, column types, nullability, etc., not comments about the structure of the table.

Well, the FAQ is where I went first, of course. And then I came up with this, "ALTER ignore table $table MODIFY message_id varchar(255) \ not null secondary key" But MySQL said I had an error in my syntax. :( If I use the ADD INDEX() syntax, will that cause the message_id field to be indexed, also for new message-ids? Thanks. P.S. Yes, I know, I should have considered this when creating the table, that I might also want an index on message-id; but I can no longer drop the current table. - Mark - 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?

Apparently this doesn't work in all cases. "CHECK TABLE" told me
everything was fine, but dumping the data to a dump file via mysqldump
and then re-importing it into a new database fixed the problem, so there
must have been some undetected corruption in the database.

RE: Column Header/ Column Description
Metadata in the database is NOT a bad idea! It's a basic part of the relational model, Codd's 4th rule. (E. F. Codd is the originator of the relational model.) While no one has implemented all 12 of Codd's rules, this is pretty basic/easy. Here's the 4th rule: "The database description is represented at the logical level in the same way as ordinary data, so authorized users can apply the same relational language to its interrogation as they apply to regular data." I'm not a relational purist but metadata documentation about the database should be maintained in the database and there's no reason for it to be viewed as unnecessary overhead that would somehow slow down non-metadata queries.

Alter table
Can some please help me? I created a MySQL table with newsgroup articles in them, and indexed them on article_num, article_num int unsigned not null primary key But now, as I found out that searching on message_id, using a WHERE clause tends to get very slow. So, I was wondering whether I can change the table to have message_id be the secondary key. Now it is, message_id varchar(255) But I would like it to become, message_id varchar(255) not null secondary key Can I alter the table to this effect, or am I too late? :( Thanks, - Mark - 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?

The field types are actually a lot more important than the names... :) I don't know the tool you are using, so I can't advise on how you can find this information, but from how you describe your problem I am guessing all your fields are of type VARCHAR or TEXT. These are field types intended for storing text, and a natural choice in many cases. There is however no magic involved, mysql does not know that the words you store in the column actually are names for months, and consequently not what would be the correct calendar order of the months... :) Luckily there are more field types, specialized for numbers and dates. You could use a numeric field type, and store your months as the numbers 1,2,3...12, and your application could translate the number to a month name. "ORDER BY Month" would give the correct calendar order. You got an advise on the list to create a MonthNames table. I never do that, because it is so simple to do it programatically. However, if you can not translate the numbers to month names in your application, it may be the only way, and anyways the technique used is basic relational database theory, so if you are going to work with databases, you probably need to learn it. ;) btw, did you test the suggestion in my previous post? -- Roger - 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 even think that the table comment functionality that MySQL does have is absolutely necessary. Storing this sort of metadata in the database seems to be counterproductive to me, especially because it's only available if you know SQL and are working with the database. But that's another discussion. I would hope that developers create table and column names that are descriptive enough to get a general understanding of what's going on, and that anything that wasn't self-describing is documented in a set of "release notes" or a data dictionary. I'm also of the opinion that a picture is a much better tool for this sort of thing.

Perhaps a bit clunky, but if you store dates as "datetime", or "date" type (recommended anyway), you can simply sort numericly on them by converting them to unix_timestamp in your query, "SELECT MONTH(mydate) FROM mydates ORDER BY unix_timestamp(mydate) ASC"; The unix_timestamp is not really necessary here, as you could simply suffice to say, ORDER BY MONTH(mydate) But that was just in illustration how to easily sort on dates. :) There may be cleverer way to sort on dates, but I find the unix_timestamp to be very useful for this purpose. - Mark - 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: Assertion failure with mysql-3.23.49a/InnoDB
Michael, the assertion below looks like table corruption. Please check with CHECK TABLE your tables. If some is corrupt, dump, drop, and reimport it. The symbols file was forgotten from .49a and we cannot resolve the stack trace. You might want to try .50 in which the symbols file exists. I also added some diagnostic code to 3.23.52 which may help in future to track the problem. Regards, Heikki Copied message: . I've gotten this same assertion failure twice. I'm very confident in this machine's stability since it has survived 36 hours worth of CTCS, so I'm not going to look for a hardware problem just yet.

Databases with Tables approaching several million
Hello, I'm looking for a solution to a database problem I'm having. The current implementation is a file based database of roughly 57 million entries. I'm wondering if anyone has had any experience running a mysql based database with 50-100 million entries ? I was told that mysql was optomized to be fast, and would not be able to handle databases of large sizes and I'm just wondering if this is largely true or not.

RE: Column Header/ Column Description
Most of my database work has been on DB2/400. (This the native database for IBM's AS/400 series.) The reason this is important to me is because I'm transferring data from DB2/400 to MySQL. The MySQL database is optimized for reporting purposes. Most users will access the data via ODBC and, as much as possible, I want the database to be self documenting so that users can be confident they are using the correct data. I guess this is one of those situations where I'll just have to punt.

RE: Column Header/ Column Description
That's why there is a seperate area called "documentation" . why let MySQL software run slower and/or eat up more memory space with a useless feature. You can always document your specifications in a document, it doesn't have to be stored on the tables themselves. If you really want that documentation to be in your database, you can create a table with table_name, field_name, field_description columns and enter the information there. Just my 2 cents on this..

Your thoughts would be appreciated. This is usually documented in your data model, not the database itself. Whether or not that's an Erwin or Visio diagram, or a mysqldump that's annotated. I'm interested in hearing what databases you have used that have this functionality? SQL server and Oracle do not, for example. -Mark - 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?

Error writing file
Hey all, I'm attempting to create a new table within a database. I have tried from the mysql client and also from dbtools. Here is the error message I am receiving: ERROR 3: Error writing file './path_to/file.frm' (Errorcode: 28) I am trying to add the table as root. I have checked the file permissions within the dbase directory and the permissions for all files is "mysql:mysql". Any suggestions or tips (maybe I'm just being stupid here) would be greatly appreciated. Thanks very much.

Newbie asks error 1036 table read only?
Hi, I recently inherited a Mysql 3.23.46 database, have some old ISAM tables on which I am unable to do updates or inserts. I get error message #1036 'Table is read only.' I am able to sign on to the database through the root, set myself up as a superuser in the user table, and have been able to set up test tables and make inserts etc. so it doesn't look like a permissions issue. I thought that converting the tables to myisam might help but of course I get the same error message. When I copied one of the smaller tables into a new table I was able to update it. (as a last resort I could do this on all the tables, but some are large and it doesn't really address why the problem occurred) Any suggestions would be very much appreciated.

One way around this is to clone the tree onto a system that has case sensitive filenames, tar it up and move it to the system where you really want it, and unpack it.

Re: MySQL & SYBASE
Hi Chris, Dear Sir/Madam seems a little formal for a public mailing list! Anyway, we use perl scripts to transfer information from Microsoft SQL server (which was and is somewhat compatable with SyBASE) use the freeTDS sybase/mssql drivers to mysql. I modeled the databse with ErWIN first then used a perl script to SELECT the data and INSERT it into mySQL. so the short answer is yes, a routine can be written that does this.

Column Header/ Column Description
Hi All, What is the convention for documenting the contents/purpose of a column in MySql? Most databases I have worked with had a way where text could be entered for each column that described the purpose and or contents of the column. It seems to me that this is something that should happen at table creation time, but I've searched for a long time and haven't found anything. A more general question might be how is meta data entered or stored for tables and columns in MySql? Can somebody point me in the right direction?

Assertion failure with mysql-3.23.49a/InnoDB
I've gotten this same assertion failure twice. I'm very confident in this machine's stability since it has survived 36 hours worth of CTCS, so I'm not going to look for a hardware problem just yet. At first I thought it may have been the glibc issue with threads overwriting each other's stacks but this time possible memory use is well under 2GB. I tried to resolve the symbols but the mysql binary doesn't appear to come with debugging symbols (or at least any that ``nm'' was able to find). Using the mysql-max-3.23.49a-pc-linux-gnu-i686 tarball binary Hopefully someone has seen this before?? /usr/local/mysql/bin/mysqld: ready for connections InnoDB: Assertion failure in thread 61456 in file ../include/page0page.ic line 515 InnoDB: We intentionally generate a memory trap. InnoDB: Send a detailed bug report to [EMAIL PROTECTED] 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 agaist is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. InnoDB: Thread 446574 stopped in file os0sync.c line 395 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=67104768 InnoDB: Thread 266306 stopped in file sync0arr.c line 336 InnoDB: Thread 8195 stopped in file os0sync.c line 115 InnoDB: Thread 12292 stopped in file os0file.c line 1175 record_buffer=131072 sort_buffer=4194296 max_used_connections=121 max_connections=300 threads_connected=60 It is possible that mysqld could use up to key_buffer_size + (record_buffer + sort_buffer)*max_connections = 1332729 K bytes of memory Hope that's ok, if not, decrease some variables in the equation Attempting backtrace.

You can check if the index are ok with CHECK TABLE; If this says the
index is ok, they are not corrupted.
You can optimize the index layout by using OPTIMIZE TABLE.
But back to the original problem:
mysql> EXPLAIN SELECT bug_id FROM bugs WHERE bug_status IN ('NEW',
'ASSIGNED', 'REOPENED');
+---+--+---+--+-+--+++
| table | type | possible_keys | key | key_len | ref | rows |
Extra |
+---+--+---+--+-+--+++
| bugs | ALL | bug_status| NULL |NULL | NULL | 139425 | where
used |
+---+--+---+--+-+--+++
The above shows that MySQL could use the index but decides to not use
this because it concludes that a table scan will be faster.
To verify this can you send us the result for the following queries:
SELECT count(*) FROM bugs WHERE bug_status IN ('NEW', 'ASSIGNED', 'REOPENED');
SELECT count(*) FROM bugs;
If the first query returns more than 30 % of the second, then MySQL
works as expected in this case.
Regards,
Monty

bug in multi-table delete in MySQL-4.0.2 ?
Hi, I'm just testing the new multi-table delete in MySQL-4.0.2 and I wonder if I'm doing something wrong with this query : mysql> DELETE FROM searchmainhardwarefr2,searchjoinhardwarefr2 USING searchmainhardwarefr2 as a,searchjoinhardwarefr2 as b,forumconthardwarefr2 as c WHERE b.numreponse=a.numreponse AND b.topic=c.numeropost AND c.date<'2002-01-01'; Query OK, 21 rows affected (0.34 sec) (I want to delete rows from searchmainhardwarefr2 and searchjoinhardwarefr2 which match the join) As you can see, MySQL display 21 row affected, but I tried the following : mysql> SELECT COUNT(*) FROM searchmainhardwarefr2 as a,searchjoinhardwarefr2 as b,forumconthardwarefr2 as c WHERE b.numreponse=a.numreponse AND b.topic=c.numeropost AND c.date<'2002-01-01'; +--+ | COUNT(*) | +--+ | 1744709 | +--+ 1 row in set (1 min 19.34 sec) That's not 21 rows :) The delete seems to erase nothing since the select was issued AFTER the delete. Moreover, the returned number of rows seems to be random : mysql> DELETE FROM searchmainhardwarefr2,searchjoinhardwarefr2 USING searchmainhardwarefr2 as a,searchjoinhardwarefr2 as b,forumconthardwarefr2 as c WHERE b.numreponse=a.numreponse AND b.topic=c.numeropost AND c.date<'2002-01-01'; Query OK, 21 rows affected (0.34 sec) mysql> DELETE FROM searchmainhardwarefr2,searchjoinhardwarefr2 USING searchmainhardwarefr2 as a,searchjoinhardwarefr2 as b,forumconthardwarefr2 as c WHERE b.numreponse=a.numreponse AND b.topic=c.numeropost AND c.date<'2002-01-01'; Query OK, 24 rows affected (0.38 sec) mysql> DELETE FROM searchmainhardwarefr2,searchjoinhardwarefr2 USING searchmainhardwarefr2 as a,searchjoinhardwarefr2 as b,forumconthardwarefr2 as c WHERE b.numreponse=a.numreponse AND b.topic=c.numeropost AND c.date<'2002-01-01'; Query OK, 28 rows affected (0.31 sec) mysql> DELETE FROM searchmainhardwarefr2,searchjoinhardwarefr2 USING searchmainhardwarefr2 as a,searchjoinhardwarefr2 as b,forumconthardwarefr2 as c WHERE b.numreponse=a.numreponse AND b.topic=c.numeropost AND c.date<'2002-01-01'; Query OK, 19 rows affected (0.44 sec) Tell me if I'm doing something wrong, and if not I will try to send a testcase ASAP at bugs mailing list.

DBI connect (help)
Hi all, I am trying to connect to my mysql database with a perl script...
I can connect from commnad line both passing a password or at password prompt...
I can connect successfully with the following line in my script..
my $dbh = DBI->connect("DBI:mysql:database=mysql;host=localhost", "root", "password",
{'RaiseError' =>1});
But the following line fails.. with a Memory fault but no core dump
my $dbh = DBI->connect("DBI:mysql:database=mysql;host=localhost" .
";mysql_read_default_file=$ENV{HOME}/.my.cnf", $user, $password);
DBI->trace(9); outputs the following
imp_dbh->mysql_dr_connect: host = localhost, port =0, uid = NULL, pwd = NULL
.my.cnf file looks like...
[client]
user=root
password=passwd
Any ideas or anything blatenly obvious as to what is wrong?

Re: download mysql GUI
Without knowing what you need to be able to do in a MySQL GUI: I have MyCC 0.8.2 from MySQL AB and dbTools 1.0.13 from www.dbtools.com.br. I like both. MyCC is alpha and a little finicky at times...but easy to use. dbTools is interesting and has a lot of potential.

Re: Is there MySQL version 4.0.2 ?
Hi, as far as I know the only way that can be correct is to have one of the committers rename the files them selves that have duplicate names.

Very new to windows version - question about host and server
Group, I have been using (very happily) mysql on unix boxes. I am in a new job and there is not a unix box in sight!!! ouch! This is a windows 2000 shop. Here is the situation and I am looking for any and all suggestions: 1) I have mysql, apache, perl, etc running on my own box and I have just installed mysql on the main server ( also windows 2000). 2) How do I access my new mysql databases on the server? 3) Does it have to do with the -h parm? Any and all help would be appreciated. If I have not been clear enough - I will try to add more.

Re: Best book on MySQL
At 04:34 PM 5/14/2002, you wrote: >I'd be interested in how both of you compared them. > >Thanks, >--jeff Jeff, I'm using MySQL for a webserver and didn't really want to use Firebird (Interbase) for that type of application. It is my feeling that IB requires more maintenance than MySQL. It's peculiar transaction scheme requires the database to be swept from time to time (daily if you do a lot of updates) to get rid of the old records. If you update or delete a record, the old record isn't really deleted. The new record has a higher transaction number so it gets retrieved over an older one. This means updated/deleted records stick around until it is swept (which is an automatic process) and this may have an effect on performance. This type of transactions is really fast if you are doing a lot of rollbacks because rolling back thousands of records takes just milliseconds. IB is a feature rich relational database. It has everything you could ever want in a database. Triggers, stored procedures, calculated fields. You can also write your own functions in a Delphi or CB dll and call them as if they were another IB function. People normally don't recompile the IB source, at least not as much as with MySQL. IB runs on Windows, Linux, and Solaris. BUT IB is much more CPU intensive for the same # of users than MySQL. There used to be a limit of 254 concurrent users but I believe that limit has been surpassed with the Linux version. I don't know how well IB will run with that many users because the CPU may max out before then. There is also a question of connection speed on a web server. Most people would use persistent connections and employ middleware to connect more than 254 users at a time. Middleware like Midas (Borland) of course costs money. The price of Midas has dropped in the past few years from around $2500 per server to around $250. I would also be a bit hesitant to put more than say a million rows in an IB database. This is just me, mind you. Some people have successfully put 100 million rows into IB tables. My hesitation comes from the fact that IB will slow down if there are a lot of updates, even with sweeping. You need to unload and reload the data occasionally. And IB inserts data at a much slower rate than MySQL. So if it is run on a webserver, it means more down time. It could take a couple of days to reload 100 million rows in IB. My personal feeling is that IB is better suited to vertical market applications or for corporate databases where they absolutely need referential integrity. Here they can take the database down overnight, do maintenance on it, and it won't affect anyone. This is difficult to do if it us running on a webserver. If your webserver is readonly and has a low number of concurrent users, then IB might be worth a look. IB (Firebird) licensing is also much more liberal than MySQL because Firebird applications can be distributed freely on all platforms, even for commercial use. Sadly there aren't any books on Interbase. The last one was printed in 1997 (Ken Henderson) and dealt with accessing IB from Delphi applications. All of the documentation is in PDF files and IB is well documented (but fragmented in a lot of PDF files). For more information, see http://firebird.sourceforge.net/ and http://www.ibphoenix.com/ . Well, that's my 2 cents worth. IB (Firebird) is heavy duty database and exceeds PostgreSQL in features. So if you're leaning towards PostgreSQL, you may want to look at Firebird. It's not the fastest database on the block, but it is feature-rich. (chubby?).

Re: building mysql-4.0.1 (libtool question)
Okay, I believe the problem I am having is make is having some problemsis in
libmysql.c when the getenv fucntion is used.
I commented out the following lines in libmysql.c and then the program errored in the
next line with getenv. Anyone have a workaround for this code on HP-UX 11.00?
if (!passwd)
{
passwd=mysql->options.password;
#ifndef DONT_USE_MYSQL_PWD
if (!passwd)
passwd=getenv("MYSQL_PWD"); /* get it from environment (haenke) */
#endif
}
The next line that then errored was...
if ((env = getenv("MYSQL_UNIX_PORT")))

Reset Master command ignores max_binlog_size variable
Hi all, Were running replication on our Prod. DB (3.23.42 on SuSE 7.0) since a half year. Our way to rotate the binlog files was to stop all software inserting data into the Prod. DB and then reset the master and the replication server. This works fine but produces a downtime of aprox. 10 minutes every time we rotate the files. In the last week were tryout a new procedure to rotate the binlog files. First we locked all tables for writing, wait until the replication server has executed all outstanding SQL Querys and then reseted the master and the replication server. This produces a downtime of less than 2 minutes only. But after we restarted the replication, the master writes all updates into one binlog file which grows up and up. If the binlog file reached the filesystem limit of 2GB (on ext2) all updates written to the file are lost and the replication stops without any error message. The strange thing is that we set the max_binlog_size variable in the my.cnf file to a limit of 30MB. The variable will be ignored if we use the new procedure to rotate the binlog files but works fine with the old one. The final result now is that the DBs are out of sync and we have to spend a downtime of aprox. 45 minutes to bring the DBs back in sync. Does anybody knows the reason for that problem and have a fix? Is this strange behavior a bug or a goodie? I searched through the mailinglist and the web but could not find any solution yet.
