Seen this a lot with poorly written web apps which open connections but dont

I think you are wrong, slaves will always accept writes unless you

Due to this, and if you dont specifically set readonly on the slave

You are correct, in a master slave setup the slave does not accept writes.

In mysql configuration file (my.cnf) you have given

For 32bit OS it should be less than or equal to 4GB and for 64bit it can be

Hi Michale,
I have made that parameter column name change. but I am unable to
understand how even after execution of update statement and commit
after that, data is getting reverted.
Any inputs on this will be a great help.

You might have better results if you use unique identifiers:
Select MyID From Test Where TestID = TestID;
I'm not sure how mysql is supposed to tell the param 'TestID' from the
column name.

Unless you have a very good reason, you probably shouldn't go with
cluster in the first place. If it is HA you want to have, check out
other options like MMM for MySQL (http://mysql-mmm.org), DRBD
+Heartbeat and others.
Can you tell us a bit more about your goals/desires?

OOM is configurable via the proc filesystem via /proc//oom_adj .

is a very big. I think Apache with cgi-scripts not critical process in this

You don't want to mess with OOM too much - you risk it killing off other
useful/critical things, like SSH daemons, the Apache root, what have you.
Add more memory to the box or split the webserver off to another system, I'd
say.

Mysql used 5GB (buffers + 400 connections) of memory, but CGI-script some
time made heavy load when used many memory and used SWAP. OOM-killer must
kill new cgi-forks, wich use many memory, but it kill mysqld and sshd.

It would be a lot better to make sure your server doesn't turn
OOM-psycho on you. The most common case of this happening is that you
have set the memory-settings in your my.cnf in such a way that it
allows MySQL to use more memory then you have available. Could you
post your my.cnf here by chance?

You can hope that's not not necessary in order to deliver the requested

happens that accomplish
