開発環境のWindows XP Pro + MySQL 5.4.1betaでmy-small.ini使っても起動時にメモリを1GBくらい使われるのでmy.iniを編集してみた。
本番環境がMySQL 5.4.1-betaだけど、起動するとメモリが多い。
Process Explorer のvirtual memoryで見てみた。
java 1.6.0_11b3 - -
eclipse 3.3.1.1 - 800MB
tomcat 5.5.26 - 1GB
mysql 5.4.1-beta - 1GB
firefox 3.5.7 - 500MB
> set MYSQL_HOME=C:\mysql PATH=%PATH%;%MYSQL_HOME%\bin;
eclipseとjavaのパッケージとtomcatはめんどくさいのでとりあえずmysqlの利用メモリを削りたいので色々見てみた。場合によってcolinux環境が混ざってるのでコマンド名は適当に読み替えて。
my.iniって何が読み込まれてるの？コマンドでは出ないみたいだけど。
MySQL :: MySQL 5.1 リファレンスマニュアル :: 3.3.2 オプションファイルの使用 http://dev.mysql.com/doc/refman/5.1/ja/option-files.html ファイル名 目的 WINDIR\my.ini グローバルオプション C:\my.cnf グローバルオプション INSTALLDIR\my.ini グローバルオプション defaults-extra-file --defaults-extra-file=pathで指定されたファイル（あれば）
どんな値を変更したら良いかわからないので現状の値をだす。
$ mysqladmin variables -hhostname -uuser -p mysql> show variables; #以下はデフォルト値？

my.iniに数字でかそうなところを小さくしたりとか、connectionを削除してみるとか、latin1をutf8にしたりして再起動、で失敗するのでエラーログを見てみる。
