H2データベースの起動オプション

$ java -cp lib/h2-1.4.199.jar org.h2.tools.Server -web -webAllowOthers -tcp -tcpAllowOthers -ifNotExists

h2-1.4.199で存在しないデータベースにアクセスしたときに新しいデータベースが作られないという問題が発生した．

ifNotExists があると，存在しないデータベースにアクセスしたときに自動でデータベースが作られる．

webAdminPassword がないと管理者ツールにアクセスできないようになった．起動オプションに渡すのはうまくいかなかった．.h2.server.propertiesに webAdminPassword=9999 のように書けば良い．
