Mysql innobase_buffer_pool_size can't be over 4GB on 32-bit systems.

Solution Verified - Updated -

Issue

  • System seams to address more than 4 Gb but it cant be used by mysql server: when trying to tune up mysql's config file,setting 'innobase_buffer_pool_size' to 10Gb which cause mysql to throw this error at startup:

[ERROR] innobase_buffer_pool_size can't be over 4GB on 32-bit systems
I can only set it to 2Gb only !

  • Is there any way to let MySQL address more than than 2 gb on a 32-bit system ?
