我正在尝试导入旧的Vbulletin数据库但总是收到此错误

ERROR 1114 (HY000) at line 4734: The table 'session' is full

此数据库备份大小为2GB，我的服务器有8GB内存。我尝试将innodb_data_file_path=ibdata1:10M:autoextend和innodb_file_per_table添加到my.cnf但未解决我的问题。

我的完整my.cnf

#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
# 
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...
# Remember to edit /etc/mysql/debian.cnf when changing the socket location.

我非常熟悉Vbulletin数据库架构和表。我已经将几十个VB站点转换为Innodb storage engine。

您收到该错误的原因是session表是Memory表。当您尝试恢复此备份时，session表必须已满。在导入过程中加上您的开销IO，就会填满你的RAM。但是，为了使VB正常工作，您实际上并不需要将此表作为Memory表。

为了解决此问题，您可以将session表转换为InnoDB。

我会在文本编辑器中打开.sql文件（如果可能），并将ENGINE = MEMORY表的session更改为InnoDB，或使用字符串替换：< / p>

sed -i 's/MEMORY/INNODB/g' yourfilename.sql

ERROR 1114（HY000）第4734行：表格已满
