Hi,
you can see the monitor's output in the logfile. In my case (mandrake linux), it is in
/var/lib/mysql and I do:
tail -f /var/lib/mysql/SERVERNAME.err
Also, where do I designate autocommit = 0;
Use SET AUTOCOMMIT = 0 as a SQL query. Just issue it where you do your SELECT,
UPDATE etc.

Heikki,
The output I get from the Monitor does not have the section

sorry
Heikki,
thanks for the reply. Regarding the trace output, My test has been
bombarding the db server with 15 simultaneous clients, each
generating up to 1000 transaction sets.
I still do not get any output from Innodb Monitor.
I created table innodb_monitor in the database that I'm accessing
Innodb Monitor.

Should it be created instead in the database mysql??
No, it does not matter in which database you create it.
Here is a sample session I ran in NT:
mysql client:
C:\mysql4\binmysql test
Welcome to the MySQL
Heikki,
I looked at the mysql error log and all the stuff was there.
I was expecting it on the standard output as the documentation said.
Thanks again. I'll have to restart the server again since the
innodb monitor output on the error log says that I'm not running a debugable
version, so

Is there any sample that I can
again since the
innodb monitor output on the error log says that I'm not running a debugable
version, so there is no information about locking. So, I should issue
It actually means 'no information about semaphore locking'.
You will get the user lock info with
innodb_lock_monitor
not with plain
\binmysqld-max-nt --standalone --console

Like I show below
Gisella,
sorry, the printout in InnoDB Monitor is
ambiguous in its words: non-debug version
there means a version not compiled with
#define UNIV_SYNC_DEBUG
in univ.i
The monitor in .44 does not use the ambiguous
term any more.
But you do not need semaphore info, only user
lock info. When I
generate secondary indexes?
Regards,
Gisella

Hello,
I'm running into the 100 deadlock error, so I would like to trace the
problem.
Server: mysqld-max-nt 3.23.43
myodbc 2.50.39
Server application that connects to mysqld is multithreaded.
Mysqld has been installed as a service.
I stopped it. Then I issued the following command:
Gisella,
.43 only prints info when there is MySQL server
activity. I have changed it to .44 so that it
always prints info every 15 seconds, regardless of
server activity.
If you want to study locks, then
innodb_lock_monitor
is the right tool.
About your other question, I am afraid that
