Hi!
I need a little help from you…
I have a problem with makeing back-up to our database.
We work with MY SQL in PhpMyAdmin, and we have a db large than 25 M. (This db was created by a Vtiger CRM, and he increase permanently.)
Is not to big but enought to create problems to us.
Problems apear when we want to make a back-up because mysql don’t let us to make it.
I try to export (460 tables) and it export only 190 (I think that back-up never pass 6.5 M). When I export archived it give me all the time something with 0k.
I try to save it like plain text and to move it with copy paste in another place…but he never get me all my database. The text apear to be cuted somewhere in the middle. (so…it doesn’t help).
I also try to make mysqldump from command prompt, and it seems it work…but actualy nothing happend. No back-up is created in the place where I tell to create…and it don’t get me an error.
After some researchs I belive that the problem came from my.ini where I have an unwanted limit. Another probleme apear here because I don’t know which one.
This is my “my.ini”
Example MySQL config file for small systems.
This is for a system with little memory (<= 64M) where MySQL is only used
from time to time and it’s important that the mysqld daemon
doesn’t use much resources.
You can copy this file to
E:/Program Files/xampp/mysql/bin/my.cnf to set global options,
mysql-data-dir/my.cnf to set server-specific options (in this
installation this directory is E:/Program Files/xampp/mysql/data) or
~/.my.cnf to set user-specific options.
In this file, you can use all long options that a program supports.
If you want to know which options a program supports, run the program
with the “–help” option.
The following options will be passed to all MySQL clients
[client]
password = your_password
port = 3306
socket = “E:/Program Files/xampp/mysql/mysql.sock”
Here follows entries for some specific programs
The MySQL server
[mysqld]
port= 3306
socket= “E:/Program Files/xampp/mysql/mysql.sock”
basedir=“E:/Program Files/xampp/mysql”
tmpdir=“E:/Program Files/xampp/tmp”
datadir=“E:/Program Files/xampp/mysql/data”
skip-locking
key_buffer = 16M
max_allowed_packet = 1M
table_cache = 64
sort_buffer_size = 512K
net_buffer_length = 8K
read_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M
log_error=“mysql_error.log”
Don’t listen on a TCP/IP port at all. This can be a security enhancement,
if all processes that need to connect to mysqld run on the same host.
All interaction with mysqld must be made via Unix sockets or named pipes.
Note that using this option without enabling named pipes on Windows
(via the “enable-named-pipe” option) will render mysqld useless!

Replication Master Server (default)
binary logging is required for replication
log-bin deactivated by default since XAMPP 1.4.11
#log-bin=mysql-bin
required unique id between 1 and 2^32 - 1
defaults to 1 if master-host is not set
but will not function as a master if omitted
server-id = 1
Replication Slave (comment out master section to use this)
To configure this host as a replication slave, you can choose between
two methods :
1) Use the CHANGE MASTER TO command (fully described in our manual) -
the syntax is:
CHANGE MASTER TO MASTER_HOST=, MASTER_PORT=,
MASTER_USER=, MASTER_PASSWORD= ;
where you replace , , by quoted strings and
by the master’s port number (3306 by default).
Example:
CHANGE MASTER TO MASTER_HOST=‘125.564.12.1’, MASTER_PORT=3306,
MASTER_USER=‘joe’, MASTER_PASSWORD=‘secret’;
OR
2) Set the variables below. However, in case you choose this method, then
start replication for the first time (even unsuccessfully, for example
if you mistyped the password in master-password and the slave fails to
connect), the slave will create a master.info file, and any later
change in this file to the variables’ values below will be ignored and
overridden by the content of the master.info file, unless you shutdown
the slave server, delete master.info and restart the slaver server.
For that reason, you may want to leave the lines below untouched
(commented) and instead use CHANGE MASTER TO (see above)
required unique id between 2 and 2^32 - 1
(and different from the master)
defaults to 2 if master-host is set
but will not function as a slave if omitted
#server-id = 2
The replication master for this slave - required
#master-host =
The username the slave will use for authentication when connecting
to the master - required
#master-user =
The password the slave will authenticate with when connecting to
the master - required
#master-password =
The port the master is listening on.
optional - defaults to 3306
#master-port =
binary logging - not required for slaves, but recommended
#log-bin=mysql-bin
Point the following paths to different dedicated disks
#tmpdir = “E:/Program Files/xampp/tmp”
#log-update = /path-to-dedicated-directory/hostname
Uncomment the following if you are using BDB tables
#bdb_cache_size = 4M
#bdb_max_lock = 10000
Comment the following if you are using InnoDB tables
#skip-innodb
innodb_data_home_dir = “E:/Program Files/xampp/mysql/data”
innodb_data_file_path = ibdata1:10M:autoextend
innodb_log_group_home_dir = “E:/Program Files/xampp/mysql/data”
#innodb_log_arch_dir = “E:/Program Files/xampp/mysql/data”
You can set …_buffer_pool_size up to 50 - 80 %
of RAM but beware of setting memory usage too high
innodb_buffer_pool_size = 16M
innodb_additional_mem_pool_size = 2M
Set …_log_file_size to 25 % of buffer pool size
innodb_log_file_size = 5M
innodb_log_buffer_size = 8M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50
[mysqldump]

max_allowed_packet = 60M

Thenk you in advance and sorry for my poor english! I wish you a good day!
