Question

i am trying to increase tomcat memory by adding JAVA_OPTS in catalina.bat as follows:

rem   TITLE           (Optional) Specify the title of Tomcat window. The default
rem                   TITLE is Tomcat if it s not specified.
rem                   Example (all one line)
rem                   set TITLE=Tomcat.Cluster#1.Server#1 [%DATE% %TIME%]
rem
rem
rem
rem $Id: catalina.bat 1146096 2011-07-13 15:20:43Z markt $
rem ---------------------------------------------------------------------------

JAVA_OPTS="-Djava.awt.headless=true -Dfile.encoding=UTF-8 
-server -Xms1536m -Xmx1536m
-XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=256m 
-XX:MaxPermSize=512m -XX:+DisableExplicitGC 
-XX:UseConcMarkSweepGC 
-XX:CMSPermGenSweepingEnabled 
-XX:CMSClassUnloadingEnabled"

但是,在管理启动或关闭文字时,正在跟踪计算机辅助器中的错误:

 JAVA_OPTS  is not recognized as an internal or external command,
operable program or batch file.
 -server  is not recognized as an internal or external command,

请告知为何我正在找他们。

Answer 1

Try:

set JAVA_OPTS=-Djava.awt.headless=true -Dfile.encoding=UTF-8 ^
-server -Xms1536m -Xmx1536m ^
-XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=256m ^
-XX:MaxPermSize=512m -XX:+DisableExplicitGC ^
-XX:+UseConcMarkSweepGC ^
-XX:+CMSClassUnloadingEnabled

You need to use the set command to set an environment variable.
If you want to split a command over multiple lines in a windows bat file you need to add a ^ (caret) at the end of each line.
No quotes necessary.

Answer 2

在每个新行端清除空位。

JAVA_OPTS="-Djava.awt.headless=true -Dfile.encoding=UTF-8[ENTER]
-server -Xms1536m -Xmx1536m[ENTER]
