Solve the ERROR 2006 (HY000): MySQL server has gone away without change the max_allowed_packet

Question

I'm trying to import a SQL database file which is 750MB by using ssh into my new database. The Sql1043724_1.sql is already on the server.

When I run this command:

mysql -u u77066539X -p u770665391_db < Sql1043XX_1.sql

I get:

ERROR 2006 (HY000) at line 5262: MySQL server has gone away

Unfortunately, in the /etc/my.cnf file I have max_allowed_packet=16M and I cannot change it because I don't have a root account. I asked to my hosting provider and they cannot change the value for me.

Is there any other procedure that I can use to solve my problem and import my old database?

Thank you!

Answer 1

The maximum packet size relates to how long a line of SQL can be in the .sql file. The size of the file itself does not matter.

I have found success with overcoming this problem but I configured both the server and use a command line to use a large packet size. Try this:

mysql -u u77066539X -p --max_allowed_packet=1073741824 u770665391_db < Sql1043XX_1.sql
