若是已控制檯方式啓動tomcat,能夠修改catalina.bat文件來設置java內存大小,java
set LOGGING_MANAGER=-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager :noJuliManager set "JAVA_OPTS=%JAVA_OPTS% %LOGGING_MANAGER%" rem 內存設置 set "JAVA_OPTS=-Xms1024m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=256m" rem ----- Execute The Requested Command --------------------------------------- echo Using CATALINA_BASE: "%CATALINA_BASE%" echo Using CATALINA_HOME: "%CATALINA_HOME%" echo Using CATALINA_TMPDIR: "%CATALINA_TMPDIR%"
若是經過命令service.bat install將tomcat安裝爲系統服務,修改catalina文件並不會生效,而須要修改service.bat文件,找到以下配置部分,修改--JvmMs 和 --JvmMx便可使設置生效apache
"%EXECUTABLE%" //IS//%SERVICE_NAME% ^ --Description "Apache Tomcat 7.0.72 Server - http://tomcat.apache.org/" ^ --DisplayName "%DISPLAYNAME%" ^ --Install "%EXECUTABLE%" ^ --LogPath "%CATALINA_BASE%\logs" ^ --StdOutput auto ^ --StdError auto ^ --Classpath "%CLASSPATH%" ^ --Jvm "%JVM%" ^ --StartMode jvm ^ --StopMode jvm ^ --StartPath "%CATALINA_HOME%" ^ --StopPath "%CATALINA_HOME%" ^ --StartClass org.apache.catalina.startup.Bootstrap ^ --StopClass org.apache.catalina.startup.Bootstrap ^ --StartParams start ^ --StopParams stop ^ --JvmOptions "-Dcatalina.home=%CATALINA_HOME%;-Dcatalina.base=%CATALINA_BASE%;-Djava.endorsed.dirs=%CATALINA_HOME%\endorsed;-Djava.io.tmpdir=%CATALINA_BASE%\temp;-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager;-Djava.util.logging.config.file=%CATALINA_BASE%\conf\logging.properties" ^ --JvmMs 1024 ^ --JvmMx 1024
