I do not think there is anything wrong with having one huge file is there?
We have one innodb file of 85GB on ext3.
Is there?
but how about the problem on the file has been increasing continuously?
thanks

Hi Vokern,
I suggest to have a single ibdata1 file and use innodb_file_per_table to
have multiple .ibd tables.
Can I upgrade to innodb_file_per_table smoothly?
thanks.

Hello,
Currently I have the setting:
innodb_data_file_path=ibdata1:10G;ibdata2:10G;ibdata3:10G;ibdata4:10G:autoextend
Because the last file of ibdata4 is very large (more than 50G), if I
want extend the data to more files, for example, ibdata5, ibdata6...
how to do it?
Thanks!

Hello,
We are using mysql-5.1 with innodb engine for a web 2.0 application.
But we found that the performance is not that good, i.e, the IO load
sometime is high, the query is timeout.
We run ubuntu server Linux, with apt-get for installing mysql.
So is there any good document for improving mysql
. Have you changed any of
the default buffer and cache sizes as yet?
Regards
Machiel

If its an IO problem the first and easiest thing to do is (probably) look at
your disk subsystem. You can easily achieve higher disk IO by increasing the
number of disks and implementing something like RAID1+0. What is your
current disk configuration?

Thank you all for the kind helps.
I will check them and if still have problems I will come back.

Quoting vokern vok...@gmail.com:
The disk is exactly Raid10.
The CPU is two 2.5G*4, totally 16G memory.
And how many disks do you have, and what type (SATA/SAS/FC etc) what RPM? To
improve IO you can add more disks, or upgrade to faster disks.
Two disks
This is piece of the setting in my.cnf:
set-variable = innodb_buffer_pool_size=4G
set-variable = innodb_additional_mem_pool_size=20M
set-variable = innodb_flush_log_at_trx_commit=2
set-variable =
innodb_data_file_path=ibdata1:10G;ibdata2:10G;ibdata3:10G;ibdata4:10G:autoextend
key_buffer
And this is the innodb file size, does this matter for performance?
$ du -h ibdata*
11G ibdata1
11G ibdata2
11G ibdata3
59G ibdata4
