Hi,
After analysing slow query log i found that some queries are not using index
and so i used the force index command in query and test it and now it starts
using index properly.Accordingly i implemented the same query with force index
in my application code and regeneratet the slow query
It seems that one of the tables we need to export and import

Some other info you can post to the list to help us zero in on the problem:
1) What is the SQL used to update the tables
2) What is the table structure? Show Create Table mytablex
3) How long does it take for how many rows?
4) How busy is the CPU when the updates are occuring?
5) Show Status --
Hi:
I want to upgrade a master and slave server from mysql 4.1 to mysql 5.1.
I want to so something like follows:
1. Stop all write access to the master server.
2. Ensure that replication on the slave is caught up to the last change
on the master.
3. stop binary logging on the master.
4.
How about:
1 shut down the slave, upgrade it, restart it, let it catch up.
2 shut down the master, upgrade it, restart it, let the slave catch up.
?

Hi:
I want to ensure that right after the reload that the same data is
present in both the master and the slave. They are in perfect sync. Then
I think its safe to consider starting binary logging and replication
etc. And after these are started, changes can start?

Anyone have information they can provide on the performance hit of using
innodb_file_per_table?
I'd assume that since there are many individual tables that this would
slow performance, but perhaps not.
In a huge database, is this not a good idea, or a better one?

Frankly, I didn't entirely understand what you were proposing. I got lost
around step 6.
Is the issue total time for the procedure or service downtime?

Hi,
The step 6 in simple terms is
Here we need to build two server ( both master and slave ). Instead of
building two server as it takes double the time of building in one server.
After building an server, make a copy of the first server files at OS level
and copy it to the server and start the
