    text
    copied!<p>Im using Wampserver version 2.0 . When i try to import a sql file, either through MySQL Query Browser or PHPMyAdmin,i get the following error.</p> <pre><code>Error 2006: MySQL Server has gone away. </code></pre> <p>The size of the file is 54,528 KB.</p> <p>In C:\wamp\bin\mysql\mysql5.1.30\my.ini , i set the max_allowed_packet to 100M in [mysqldump] and [wampmysqld]. I couldnt find wait_timeout variable in my.ini. Any way to fix this problem ?. For your reference, i have given below the contents of my.ini file.</p> <pre><code># Example MySQL config file for medium systems. # # This is for a system with little memory (32M - 64M) where MySQL plays # an important part, or systems up to 128M where MySQL is used together with # other programs (such as a web server) # # You can copy this file to # /etc/my.cnf to set global options, # mysql-data-dir/my.cnf to set server-specific options (in this # installation this directory is C:\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 = /tmp/mysql.sock # Here follows entries for some specific programs # The MySQL server [wampmysqld] port = 3306 socket = /tmp/mysql.sock skip-locking key_buffer = 16M max_allowed_packet = 100M 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 basedir=c:/wamp/bin/mysql/mysql5.1.30 log-error=c:/wamp/logs/mysql.log datadir=c:/wamp/bin/mysql/mysql5.1.30/data # Don't listen on a TCP/IP port at all.

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 = &lt;hostname&gt; # # The username the slave will use for authentication when connecting # to the master - required #master-user = &lt;username&gt; # # The password the slave will authenticate with when connecting to # the master - required #master-password = &lt;password&gt; # # The port the master is listening on. # optional - defaults to 3306 #master-port = &lt;port&gt; # # binary logging - not required for slaves, but recommended #log-bin=mysql-bin # Point the following paths to different dedicated disks #tmpdir = /tmp/ #log-update = /path-to-dedicated-directory/hostname # Uncomment the following if you are using InnoDB tables #innodb_data_home_dir = C:\mysql\data/ #innodb_data_file_path = ibdata1:10M:autoextend #innodb_log_group_home_dir = C:\mysql\data/ #innodb_log_arch_dir = C:\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] quick max_allowed_packet = 100M [mysql] no-auto-rehash # Remove the next comment character if you are not familiar with SQL #safe-updates [isamchk] key_buffer = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [myisamchk] key_buffer = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout [mysqld] port=3306 </code></pre>
