Remember, whatever you allocate for, leave enough RAM for DB Connections and the Operating System.To install SQLyog with Wine Install Wine on your Ubuntu system using the Synaptic Package Manager. If you have 2GB RAM and 4GB of MyISAM Indexes and 16GB InnoDB, allocate 512M as key_buffer_size and 512M as innodb_buffer_pool_size. If you have 2GB RAM and 4GB of MyISAM Indexes, allocate 512M as key_buffer_size. If you have 2GB RAM and 16GB of InnoDB, allocate 512M as innodb_buffer_pool_size. If you have limited memory, a mixture of storage engines, or a combination thereof, you will have to adjust for different scenarios. No powers less that 0 or greater than 3 is accepted.(SELECT 3 PowerOf1024) gives the Setting in Gigabytes.(SELECT 2 PowerOf1024) gives the Setting in Megabytes.(SELECT 1 PowerOf1024) gives the Setting in Kilobytes.(SELECT 0 PowerOf1024) gives the Setting in Bytes.Step 4) service mysql start (ib_logfile0 and ib_logfile1 are recreated)Īt the End of both queries is a an Inline Query : (SELECT 2 PowerOfTwo) B.(NNN should be 25% of innodb_buffer_pool_size or 2047M, whichever is smaller) Step 1) add innodb_log_file_size=NNN to /etc/my.cnf.I recently setup a large DB server with 4G for a single InnoDB Log File using innodb_log_file_size)įor the sake of simplicity, given just two log files, here is how you can size them: (NOTE: Percona Server binaries surpass this. MySQL Source Code places a cap of the combined sizes of all InnoDB Log Files must be < 4G (4096M). This will give the Recommended Setting for the size of the InnoDB Buffer Pool ( innodb_buffer_pool_size) given your current data set.ĭon't forget to resize the InnoDB Log Files (ib_logfile0 and ib_logfile1).

The main mechanism used is the InnoDB Buffer Pool. This will give the Recommended Setting for MyISAM Key Cache ( key_buffer_size) given your current data set ( the query will cap the recommendation at 4G (4096M). Table_schema NOT IN ('information_schema','mysql')) AA ) A, To size your key cache, run the following query: SELECT CONCAT(ROUND(KBS/POWER(1024, The main mechanism used is the key cache. Before allocating memory to either engine, it is good to reflect on what caching goes with each Storage Engine Configuring for MYISAM
