@Badera, did you restart the MySQL server after changing configuration?

Also, just before attempting the import, try

set session max_allowed_packet=128000000;

from within the mysql-client session (or just add this statement at the very top of the SQL file you are importing). I have no idea if this statement still works in current versions of MySQL – please post if it does [not].

@Badera, do you really get error 2006? Maybe your error is just different.

@Bogdan:
I also tried 128MB for the 82MB dump file, no success.

@Badera,

if that entire dump is wrapped in a transaction, then you may need to set max_allowed_packet to e.g. 96MB (basically, anything larger than your dump size). But that’s just a guess.

What can I do when those two entries

max_allowed_packet= 64M
wait_timeout= 6000

are not enough to restore a 82MB database via

mysql> \. thedumpfile.dmp

I am fiddling around for 2 days now without any success – any other idea than the two lines? (MySQL Server 5.5.16)

RipleySW2,

You saved me! I was almost crying, trying to import babushkaslots.com mySQL DB! Luckily your advice worked like a charm and the dinner with my wife was saved!!!

BTW, WAMP have a really nice interface to get to the config. files

Thanks again,
Hungry Tim

I’m running a wamp server 1.7.2

…having error 2006 server has gone away when inserting large files into my database (nothing was inserted at all).

So, simply stop the wamp server services, edit the my.ini file thru the wamp manager icon.

The 2 lines :

max_allowed_packet= 64M
wait_timeout= 6000

were added at the end of the file (c:wampmysqlmy.ini)

Restart Wamp Server Services

And it works ! Thanks a lot !

If using PHP to feed a database and getting this MySQL error, instead of modifying my.ini, try to package your data in smaller strings and put them in an array.
Then, insert one pack at a time:
foreach ($pack_array as $pack) { if ($pack != "") { $query = "INSERT INTO mytable VALUES" . $pack; $result = mysql_query($query); if (!$result) die ("Database access failed: " . mysql_error()); } }

my.ini is only available to server administrators; on a shared hosting, you normally would not have access to that file.

It worked!
The file was my.ini in mysql\bin probably, because the version is another.
Thank you very much for this guide!!
