Re: Re[32]: Warning: Got signal 14 from thread X
BAUMEISTER Alexandre writes:
Heikki,
If I run Mysql without having any client connected nor doing any
"mysqladmin xxx" command, the is no Warning messages. Only :
010326 11:43:29 mysqld started
Innobase: Started
/usr/local/mysql/libexec/mysqld: ready for connections
If I do "mysqladmin ping" , "mysqladmin status" ... no problems.
As soon as I run my daemons :
010326 11:47:28 Warning: Got signal 14 from thread 4
010326 11:47:30 Warning: Got signal 14 from thread 4
010326 11:47:32 Warning: Got signal 14 from thread 4
010326 11:47:34 Warning: Got signal 14 from thread 4
another thing really interesting is that if I do a lot of
"mysqladmin proc", then the Warning messages are paused.
I explain. I'm doing a "tail -f myserver.err" on a console. Then I
see that about each 2 seconds I got a "Warning ... message".
On another console I do "mysqladmin proc" and as soons as I get the
result I do another "mysqladmin proc" and so on ...
Then I noticed that while I'm doing "mysqladmin proc", the "Warning"
messages are no more send to error log.
A soon as I stop doing "mysqladmin proc", the "Warning" messages are
coming back :(
This seems very incomprehensible to me, but I though maybe this
could be a clue for you.
NB: I did the test with "mysqladmin ping" , "mysqladmin status" and
it's the same than with "mysqladmin proc".
Regards,
Alex.
Hi!
Seems like Innobase has introduced some timeout ( I do not see how) on
the sleeping connections.

RE: size limitation
Hi, the database I would like to managed is constitued by one table. This table is made of 3 columns, with no primary key mysql CREATE TABLE test ( id1 int(8) unsigned, id2 int(4) unsigned, id3 int(4) unsigned ); mysql CREATE INDEX idx_id1 ON test (id1); mysql CREATE INDEX idx_id2 ON test (id2); mysql CREATE INDEX idx_id3 ON test (id3); We use 3 indexes because our benchmark shown that it's better than an index on the 3 columns for our application. mysql desc test; +-+-+--+-+-+---+ | Field | Type| Null | Key | Default | Extra | +-+-+--+-+-+---+ | id1 | int(8) unsigned | | MUL | 0 | | | id2 | int(4) unsigned | | MUL | 0 | | | id3 | int(4) unsigned | | MUL | 0 | | +-+-+--+-+-+---+ Here are the request we make on this table : SELECT COUNT(*) FROM test WHERE id1=? AND id2=?; SELECT COUNT(*) FROM test WHERE id1=? AND id=2=? AND id3=?; INSERT INTO test (USER_ID, FLIGHT_ID, FLIGHTOBJECT_ID) values (?,?,?); The row size is 16 bytes. So we'll get 16 gigabytes of datas per day (it will be around 10 gigabyte in reality because only 66% of the request need an insert). The table is going to grow until we'll drop it (because of storage limitations). 10 days of lifetime for our datas will be enough :) We make no update in order to be very quick. -Message d'origine- De: Heikki Tuuri [mailto:[EMAIL PROTECTED]] Date: samedi 24 mars 2001 15:31 : [EMAIL PROTECTED]; [EMAIL PROTECTED] Objet: Re: size limitation Pascal, could you describe what indexes you should have on the data, and how you will add to it and delete from it? In order to choose a DBMS, i've to check to MySQL is able to support our requirements. I've got to manage one database. This database is made of one table. This table will grow very quickly (we evaluate that we'll have to make arround 1.000.000.000 inserts per day). Do you really mean one billion inserts per day? 1000 million inserts? If the row size is 100 bytes, you will get new data 100 gigabytes per day. If you have a terabyte of disk, you can only fit 10 days' data in it. I want to be sure that MySQL is able to manage table bigger than 1 TeraOctet. Does anyone have already use in similar condition ? I read that innobase table allows to store a table on several oracle-like "tablespace" that can be created on several disks. I think we can put the indexes on other disk too (using symbolic links). An Innobase tablespace can span 4 billion database pages, that is, 64 terabytes with the default page size of 16 kB. A single file of a tablespace can currently hold 2 GB or 4 GB depending on your OS. You would need some 500 data files in your tablespace. You cannot currently instruct Innobase where to put your data and index trees (all go into the same tablespace). But, if your table is so huge, both the data and the indexes will lie on several disks, since a single disk can store max 80 GB of data today, I think. If you have 1 billion insertions per day, that is 12 000 inserts per second around the clock. The CPU usage of Innobase would allow you to do this many insertions. The problem can be the communications overhead between your client process and the MySQL server. It might use even 100 microseconds per insert. You can reduce this overhead by using the multiple INSERT INTO ... VALUES (...), (...), (...) insertion syntax of MySQL. Another problem is the number of disks you need: if you have to make 12 000 random insertions per second, you need a disk farm of some 200-500 separate disks. The operating system will use some CPU for each disk i/o. If you have to read and write 12 000 16 kB pages each second, you need a bandwidth of 400 MB/second in your disk channel. These numbers are similar to the largest TPC-C benchmarks run today. The hardware will be expensive. You can look at www.tcp.org, where you find descriptions of the benchmark systems and their prices. I would like to know what are the requirement to store so much records. Does anyome have reference of site that manage a table bigger than 1 tera ? The largest databases in the world are of the order 4 - 40 TB. I think many of them use Teradata database machines. Some use Oracle. Did someone try that ? I hope it's possible. Otherwise, i'll to choose Oracle :( and Oracle is not cheap. Regards,-- MySQL/Innobase may be able to do what you need, but we should have a real-world test of using a big disk farm. I do not know if any MySQL user uses a disk farm. Maybe Jeremy Zawodny knows?

Re[34]: Warning: Got signal 14 from thread X
Bonjour, SM Seems like Innobase has introduced some timeout ( I do not see how) on SM the sleeping connections. I've been trying a few other things. When I run Mysql with Innobase, if no client connects, no "Warning signal 14" messages in the error log. Then I run a client which only logs on the server (no other queries). I then have to wait a few seconds (not always the same delay) before inevitably having some "Warning signal 14" messages. One message each 2 seconds : 010326 15:09:16 Warning: Got signal 14 from thread 4 Always thread 4 (even if thread 4 doesn't exist, but I've seen that while there actually was a thread Id 4). So, 1 message each 2 seconds. If I do "mysqladmin xxx" (ping, status, processlist) , there is a pause in the writing of "Warning signal 14 messages" of about 4 seconds and then ... messages are back. Then if I stop the client (so no more opened connections to Mysql), error log still receives "Warning signal 14" messages, one each two seconds. If then I do a "mysqladmin ping or status or ..." , the "Warning signal 14 messages" stop being sent to error log ... and don't come back. If I run 30 clients connecting (but doing no queries), I still have messages about signal 14 and thread 4. If I make my daemons start working (doing some update/insert queries) then I receive Warning messages but not only from thread 4, from other threads too.

Re: importing data from FileMaker Pro to MySQL
Hi, I have to import Datas From FileMaker Pro to MySQL . Unfortunately, the FileMaker web site is speaking about plugins to export databases, but the access page gives error 500 (!). Plug-ins? You don't need any plug-ins to export data to MySQL. The only plug-in for Filemaker I've ever heard of concerning MySQL is one that allowed you to access MySQL data through Filemaker. Then, I try this mailling list, and there is my question : is there any defined tool to import datas into MySQL Databases, that may also read the FileMakerPro Format, or any standard CSV format ? MySQL will import data from CSV format quite happily, with no extras required. I thought about developping something myself, in Perl (quite easy to use ...), but there is also no Perl module avaliable for FileMaker ... I would be extremely surprised if there was! I think you're getting into extremely muddy waters here. What you're trying to do is very simple. Just open your Filemaker database, export the fields you want to a tab-seperated text file, transfer that file to your MySQL server (make sure you convert Mac line breaks to UNIX too) and import the file using the LOAD DATA statement in the MySQL command-line client.

Re: Signal 11 on Innobase table range queries
Hi! I found the bug: memory was written over in the function which estimates the number of rows in ha_innobase.cc. The bug is fixed in version 3.23.36, which may be out today. You can also fix the bug by editing ha_innobase.cc, about line 2460. The last argument in the two calls to dict_index_copy_types should be key-key_parts: . range_start = dtuple_create_for_mysql(heap1, key-key_parts); dict_index_copy_types(range_start, index, key-key_parts); range_end = dtuple_create_for_mysql(heap2, key-key_parts); dict_index_copy_types(range_end, index, key-key_parts); . In the buggy version the last argument was the number of fields in the clustered index, and when the table had many columns this caused some overwrite of memory. I will run sql-bench with memory debugging switched on to check if there are similar errors. It has been a while since I last time switched memory debugging on in the tests, and that is maybe the reason the bug got past the tests.

Actually, they will be in 4.1.
And the above query does not need subselects. Try it :

Work function LOAD_FILE with replication correctly?
I'll just guess here: at the slave side, the command is ran excactly the same way.
This means that the slave will try to do a LOAD_FILE('/imag...') looking for the image
at its local fs. Of course will fail because the image doesn't reside on its
filesystem.
I think something similar was mentioned some weeks ago with regard to a LOAD DATA
INFILE... at the master side, in which case again the input_file didn't resize on the
slave filesystem and so the call failed. Correct me if i'm wrong.

RE: Re[2]: MySQL vs Microsoft SQL
James, Gotta say that this is a bad reason to choose one product vs. another... because it lacks a GUI to build queries? Undertanding SQL is all well and good, but I can tell you that I would give anything to have a query builder that works like the one for MS SQL server. You may enjoy writing incredibly long join queries because it demonstrates your understanding of SQL syntax. Personally, I'd rather spend my time watching grass grow. What is the value of doing something in code which is inherently visual, and is a lot easier to do visually? You do make a valid point, part of the reason I like M$SQL is that you can build complex expressions with their GUI tools, but Last year, I did some work for a client and he requested that I do it in-house. Now, since I was on a deadline (2 weeks), I figured I'd use the Enterprise Manager to build my stuff and off and away I go. Well, for some strange reason I was never able to determine why, but it took 15-20 minutes to connect to a database on the East Coast. When I attempted to connect via the query analyzer, the connection was instantaneous. I learned by visual means to create tables, add triggers, yada, yada, yada... Well, this was definitely a learning experience because now I had to learn how to do everything by DML via the query analyzer if I was going to meet this deadline. Now I prefer to do all my work using a command-line tool. I recently upgraded to SQL2000 on my machine at home and have encountered the same situation again! Fortunately, I can drop out of GUI-mode and work by DML until I can figure how why this happens. I understand that every user has a right to choose how they want to work, but I often see colleauges using a GUI tool to change a datatype or some other menial task (often with several mouse clicks and waiting for the GUI tool to open up) which can cause one to lose more productivity when more often than not, to do it one simple command from a production standpoint makes no sense to me. A query builder will not make a database developer out of a novice, but it can make a professional developer's job a lot easier. True. I can spend my time writing complex code that can't be done with a tool, and not waste it doing repetitive, boring joins that take a few seconds with a visual tool. That's where I do agree with you, and one of the things I don't like about M$SQL. To a certain degree, wizards are nice, but when it lulls a user into a false sense of security about being able to build queries quickly, what do you do when it doesn't become available? It's like a cashier saying to you that they can't give you change, because they don't know how to do it without a machine??!!

Re: v4.0 feature list
From this feature list, it sounds like you are creating methods
(multi-deletes, updates from joins) that will take the place of
transactions. Is this the direction that MySQL is heading? Do you believe
that these methods will be preferred over traditional rollback/commit
transactions with BDB or Gemini?

Subject: inserting into mysql database in linux using C
I am a senior in Polytechnic University working on my
senior project. I have chosen MySQL to be database in
Red Hat linux 7.0. I writing a program to insert a
value into the database in c language. The data
changes so i have to insert the data as a variable,
but the database reports a error saying that the data
is a column, the code is something like this..
int main(int argc, char **argv)
{
..
char* test;
test="abcd";
int res;
MySQL *connection;
res=mysql_query(connection, "INSERT INTO tablename
(userid) VALUES(test));
}
I get an error saying "Insert error 1054, unknown
column 'test' in 'field-list'
I don't program in c myself, but if you were doing this from the mysql
utility, the value of your variable test, would have to be in single quotes.
(ie. INSERT INTO tablename (userid) VALUES ('data to insert') )
I am guessing that your program is trying to put the raw word test into the
database, not the value of your variable.
Also looks like you forgot to close the double quote.
Do whatever you have to do to get your variable to interpolate inside the
query string.
Maybe build the query in a local variable and insert the variable into the
second parameter of mysql_query?
Querystring = "INSERT INTO tablename (userid) VALUES ('".test."')";
(I don't know what the c concatenation operator is,php uses the '.', but you
should build your query like this to put the value of test into the query
string. I also don't know the behavior of double quotes in strings, and
variables within them within c)
If you copied and pasted that query as is into the mysql client, you would
get the same error.

Depends on (a) how professional you need the reports to be, and (b) how much you can afford.. But more seriously, you *could* create a layout for "tbl" (part of GNU "groff", available for all POSIX platforms and even NT via the cygwin port), and generate output using that template: .TS H page-header specs .TH other header specs. header lines body lines-- generate this using MySQL .TE And then run all this through "tbl" followed by "groff".

Re: HELP? RE: can't find shr.o???
Jack, Mysql, Well, my thought is that I can only compile zlib as a static library. I can't compile it shared. I think this why the binary distribution of mysql doesn't work is because it is looking for shared resources of libz.a. I could go through the pain of compiling this, but the AIX freeware distribution site has a copy of mysql3.23.27 precompiled which does work fine. I know its not the very latest, but its relatively close and it works. -Thanks for your assistance! Tim Well make sure you have gcc 2.95.2 and a recent version of make (the manual suggests a version). Also, when I said "Lib paths" I meant look at the -I options for your configs. But rereading your info, it looks like a problem with the actual object file (or lack of one). I hate to say this but you may need to compile your own copy of MySQL from source. I am still rather new to this product, and my experience with aix is limited. (I did use gcc 2.95.2 to compile my copy, and had the most recent copy of glib and libc also (but they are not required), I then down loaded zlib from the link below, and then dropped the binary distro. it worked flawlessly that time (once I had the files and libs).

Jack, Yes, I made sure that I ran the command from the mysql home directory and not within scripts. I am not sure what to check with lib paths. I think it doesn't have a problem finding zlib.a in /usr/local/lib. I think it simply can't load it because it can't find the shr.o that is associated within it. I have no idea how to get around that. I even recompiled zlib and installed it for the heck of it. No difference. I also tried loading this on a 4.3.3 system we had and failed their as well. Something about my enviroment must be off. We don't have C libraries from AIX, but I do have the gcc libraries. Does any of this make a difference? Is their a particular path variable that needs a particular setting? General paths are set, but I don't think we have a libpath variable set. Most things compile ok for me. But since this is a binary distribution, we didn't compile this so I am not sure what I am exactly missing. Tim I would look into the Lib paths...though this is a quick sanity check...(I have to ask) when you execute the script mysql_install_db are you in some pathmysql-3.xx.xx-aix/ or in the scripts directory?

error cropping database/table
This is my first post to this list and I am a newbie at MySQL. If my question is a FAQ, please direct me to the FAQ board. The book I have, MySQL and mSQL by O'Reilly, says almost nothing about error codes... I'm using MySQL with WinNT4.0. I've got it up and running, however I can't drop tables after they have been created and data has been inserted into them. I get the following error: "ERROR 6: Error on delete of '.\testDatabase\member.MYI' (Errcode: 13)". And then I can' t even drop the whole database?!?! When I try to do that it gives me this error: "mysqladmin: drop of 'testDatabase' failed; error: 'Error dropping database (can't delete '.\testDatabase\member.MYD', errno: 5035465)'" And then, get this, after about 5 minutes of trying to delete the table, then trying to delete the database, getting back in and out of the database, i try dropping the database again, AND IT WORKS!!! What the heck is going on? Is there some delay in deleting a database or table? I have no idea what the problem is, and any help would be greatly appreciated.

Hello everyone, I have a few questions that I hope some of you might be able to answer. Is there a MAX_SIZE on a select statements and when does MySQL lose performance when the statement becomes very large? When using the 'IN' clause, how does MySQL parse the data? Does it do an inline search or a binary tree? Thanks for your help... --Dave J. --- Dave W. Juntgen [EMAIL PROTECTED] Medical Informatics Engineering, Inc. http://www.mieweb.com/ 4101 W.

Database or object is read-only - Error 3027
I am brand new to MySQL, attempted to find help in documentation and archives, but to no avail. I have installed MySQL on a Windows NT platform and configured a root user and another user that will act as a client with read/write permissions to one, and only one, database. A new database (exported from Access 97 into MySQL) has been created, and is accessable, however not 'updateable' from either the root user or the client user using Visual Basics 'VisData' and MyODBC (GRANT was used as documentation states to create these users). The error message I am recieving is 'Database or object is read-only - Error 3027' when I attempt to modify or add. The 'mysql' database is fully accessable (read and write) from either user however, even though permissions have not been granted to the client user. My suspicion is that either user permissions are improper, or the is some sort of database 'read only flags'? i.e. I have to modify the table in some form. I read something in the manual about 'Named Pipes' with Windows, am I going in the right direction? Can you point me in the right direction, to documentation I should look at?

RE: STUPID QUESTION
In MySQL, you can create tables that have relationships but you can't create what a lot of people call "Foreign Key relationships". In reality you CAN create Foreign key (FK) relationships between tables, you just can't create constraints that enforce them automatically. Example time: Let's say I have 2 tables, person and phone. person personID PK name phoneID FK phone phoneID phoneNumber See the phoneID in the person table? In it we store the value of phone.phoneID for this person's phone number. This is a Foreign key relationship. (So named because we are storing a foreign primary key in our table.) In other implementations of SQL, you could define a constraint (rule) that says that you can't store a value in person.phoneID that does not exist in phone.phoneID. This is a Foreign Key Constraint. So, to answer your question, to create a FK relationship between 2 tables, put a field in table1 of the same type (does not have to be the same name but I always do) as the primary key of table 2. Then when you are selecting and want to gather everything together you use: Select t1.*, t2.* from table1 t1, table2 t2 where t1.t2ID = t2.t2ID Clear as mud?

RE: STUPID QUESTION
Note that foreign keys in SQL are not used to join tables, but are used mostly for checking referential integrity (foreign key constraints). If you want to get results from multiple tables from a SELECT statement, you do this by joining tables: SELECT * from table1,table2 where table1.id = table2.id; or use alias SELECT t1.ID, t2.Name from table1 t1, table2 t2 where t1.id = t2.id ChrisB -Original Message- From: GERARDO GALLARDO [mailto:[EMAIL PROTECTED]] Sent: Monday, March 26, 2001 3:57 PM To: [EMAIL PROTECTED] Subject: STUPID QUESTION I'm new to MySQL and SQL in general.

ADO problem with MYSQL datetime column
Hi, I'm using ADO with the MyODBC driver. I have a table that I'm querying that has 'datetime' columns. If these columns are null or 0 - "-00-00 00:00:00", I have problems reading from the ADO recordset. I have other columns - char, varchar, integer etc that are null and don't have this problem. It only seems to be the datetime columns. I was wondering if this is an ADO issue with the MYSQL column type of datetime, or perhaps an issue with the MyODBC driver and ADO ? Has anyone found a work around for this problem? The only work around I've got is to actually format the field when I select it, but this creates an issue for me when I'm trying to retrieve all columns from a table that has 100+ columns. I wanted to avoid having to type out all column names in the query.

Re: speed problems
Hello. Sorry about the delay, but I was side-tracked by a server crash at the end of last week. The EXPLAIN for the 3.23 MySQL is at least as good as for 3.22, (in fact, it is better). As one fact, 996*1*1264=1258944 rows are less than 986*1*1470=1449420 rows, but at least in the same magnitude and therefore, at least in theory, the query shouldn't differ much regarding speed. I just reread the thread and saw that you compiled the newer MySQL yourself. That could make part of the speed difference, because TcX' precompiled binaries are using are well tuned (and use pgcc, which is optimized for Pentiums). Could you try a binary from www.mysql.com at least for one of the slow machines and see if it makes a difference? To be true, I am running out of ideas. On the other hand, the test environments have too much differences to easily guess which difference causes the performance hit. :-/ Were all your test cases on different machines, or did some use the same hardware, just with upgraded MySQL? Just to be sure: the machines were not used in another way during the tests, were they? Bye, Benjamin.

Maybe even (system_id,username,processname,timecode,usertime,systemtime), which should enable "using index" only. Why that, usertime systemtime are data values, they are never used in any where clause. As far as I can see it's complete waste to put index on those. If all columns of the SELECT clause are part of the index, MySQL will solve the query only with reading from the index file and never touch the data file itself. Since the index is quite big already and usertime+systemtime only add 8 bytes per row, this may pay off regarding the speed win / size increase. You may want to use partial keys in order to reduce space consumption, e.g. Maybe even (system_id,username(5),processname(5),timecode), This is a no go since alot of processes are identical on the first 5 characters. The username could be used, but I decided not to, since Oracle (which the solution also has to be compatible with) is smart enough to only store the characters in use. I actually think MySQL does the same. MySQL only stores the bytes you use, but restricting it to 5 bytes (or whatever you want), will never use more than 5 bytes. For example, I have 291383 email addresses in one database with an avarage length of 20.2 characters. Regarding the left hand characters, they are different as follows: 1 47 2 1392 320791 478516 5 142787 6 191976 7 228078 and so on. This means, a key on only 5 keys, has only to values per index entry (i.e. only half as good as a unique index) and needs 4.99 :-) characters in avarages (just measured), i.e. one save about 5MB space (out of 7MB) and now scale that up to some million rows. Okay, emails are an extreme example. :-) Depending on the Cardinality of the different columns you may want to change the order to (username,processname,system_id,timecode) or alike. Aha, I'll have to test more with the individual order of combined indexes to see what I can get from it. Well, normally that is not really important, but in your case, processname has a low cardinality and therefore one value has a lot of matches in the index and it is worth a try to put it to the right. [...] No index is chosen, because you obviouly SELECTed a major part of the table. This probably won't happen, if you got these 100 million rows are talking about below (because you won't select about 20.000.000 rows, will you?). Well, that's the problem. I will ;-( Well, in that case, no index will really help you (except the one I cited above, which should avoid reading the data file, it could help a bit). Selecting as much rows, just will take its time. :-/ [...] [clip] I have tried to combine the indexes, but then MySQL fails using them properly, Would you please elaborate on this? This is IMHO the main point of your problem. You need these indexes. Problem is that MySQL seems to do a full table scan as soon as I start to combine the indexes, even after running optimize, analyze sort after index. Normally, this means, that the index did not really fit the query, but without more information, I cannot say. Did you keep the indexes you already have now? In that case, it should use the other indexes, if it cannot use the combined index. This is my experience after looking at explain decisions and the time it takes to execute. May I bother you to add the following indexes and post the EXPLAIN after adding them:. (system_id,
