Tomcat how to set -Xms and -Xmx
If I run tomcat7w.exe (windows) there is a tab where I can set the initial
and maximum memory pool to 2560. However, I don't want to use tomcat7w.exe,
I just want to run the batch file manually (startup.bat). However, I can't
figure out how to set these memory pool values for startup.bat to use.
I read somewhere to create C:\apache-tomcat-7.0.37\bin\setenv.bat which
contains
SET JAVA_OPTS=-Xms2560 -Xmx2560
However, it doesn't work. If I run startup.bat, instead of launching the
webserver it just prints some messages and that's it. No webserver is
started.
C:\apache-tomcat-7.0.37\bin>startup.bat
Using CATALINA_BASE: "C:\apache-tomcat-7.0.37"
Using CATALINA_HOME: "C:\apache-tomcat-7.0.37"
Using CATALINA_TMPDIR: "C:\apache-tomcat-7.0.37\temp"
Using JRE_HOME: "C:\Program Files\Java\jdk1.6.0_43"
Using CLASSPATH:
"C:\apache-tomcat-7.0.37\bin\bootstrap.jar;C:\apache-tomc
at-7.0.37\bin\tomcat-juli.jar"
C:\apache-tomcat-7.0.37\bin>

+1 agreed with Charles! You should not need to change the standard
startup.bat and catalina.bat scripts, ever.
All customizations should be done through options defined in
%CATALINA_HOME%\bin\setenv.bat (or %CATALINA_BASE%\bin\setenv.bat) script.
The setenv.bat script doesn't exist by default, but catalina.bat checks for
existence of the script and calls the script if it exists, see the
following section of the default catalina.bat script:
--- catalina.bat ---
...
rem Get standard environment variables
if not exist "%CATALINA_BASE%\bin\setenv.bat" goto checkSetenvHome
call "%CATALINA_BASE%\bin\setenv.bat"
goto setenvDone
:checkSetenvHome
if exist "%CATALINA_HOME%\bin\setenv.bat" call
"%CATALINA_HOME%\bin\setenv.bat"
:setenvDone
...
--------------------
So, the intention is that you do all customizations are isolated in the
'setenv.bat' script, and they are separated from the standard scripts
(startup.bat, shutdown.bat, catalina.bat) - which makes the Tomcat version
updates very easy! No back-porting of the catalina.bat or startup.bat to
fit your new version of Tomcat.
There are two options that you can use to set the JVM memory options:
CATALINA_OPTS (for "start" and "run")
JAVA_OPTS (for "start", "stop" and "run")
I suggest you use CATALINA_OPTS for setting up memory, instead of using
JAVA_OPTS. The reason is that we are setting Tomcat(Catalina) options, and
we don't want to override JAVA_OPTS for some other Java applications.
Here's an example setenv.bat script:
--- setenv.bat ---
ECHO Executing setenv.bat script.
ECHO.
ECHO.
ECHO.
SET CATALINA_OPTS=-Xms256M -Xmx512M
------------------
Of course, you can remove first four lines after you have successfully
tested your startup script. I would suggest you start your script with
"catalina.bat run", so you can see the output of the startup command. In
the end, startup.bat is really just "catalina.bat start". Also, check the
process manager and see the actual command line that stared the java.exe
process.
Hope that helps!
Cheers!

That's completely unnecessary, and inappropriate. The call to setenv.bat is automatic. Do not change the standard startup.bat and catalina.bat scripts.

Look in the Tomcat logs for errors as to why Tomcat is not starting. If
there were existing JAVA_OPTS settings that need to be kept (which could
be preventing Tomcat from starting), use the following syntax:
Set JAVA_OPTS=%JAVA_OPTS% -Xms2560 -Xmx2560

Actually that does not work, sorry for the too-soon post. If I modify
startup.bat as follows:
SET JAVA_OPTS=-Xms2560 -Xmx2560
call "%EXECUTABLE%" start %CMD_LINE_ARGS%
It does not start the webserver, it just prints some messages and does
nothing else

That should be fine. Did it increase the memory size for you? If not,
use the CATALINA_OPTS as suggested in another post.

I just realized you do not want a "Call" in the startup.bat. Just add the setenv.bat
line before the Tomcat startup line, or add the SET statements before the Tomcat startup
line.

No. Any existing setenv.bat file will be executed before launching
Tomcat. There is no need to modify startup.bat or catalina.bat. Just
create bin/setenv.sh.

Add a "call setenv.bat" (with path as necessary) to startup.bat, or just add the relevant SET statements directly to startup.bat.

That's the wrong answer.

It's not, but you're doing it the hard way, possibly due to some bad advice earlier. Do not modify startup.bat or catalina.bat; all you need to do is create a setenv.bat file in Tomcat's bin directory, and put the following in it:
set CATALINA_OPTS=-Xms2560m -Xmx2560m
If setenv.bat exists, it will be called automatically by the startup.bat script. You should use CATALINA_OPTS here, since JAVA_OPTS applies to both the startup and shutdown, and you don't need it on stop Tomcat.
Note that the tomcat7w.exe executable is used only when running Tomcat as a service, not when launching it from batch scripts.

You don't want to do this. Instead, you want to set CATALINA_OPTS.
Read the documentation (see below) for the difference. If you set
JAVA_OPTS, you'll find yourself creating a 2.5 GiB heap just to
shutdown Tomcat as well as start it up.

It's not that difficult to figure out. Read RUNNING.txt that comes
with Tomcat (or linked directly through the documentation from the
"Setup" page... it's the first non-TOC link in the document).

I found the answer. In catilina.bat change
set JAVA_OPTS=%JAVA_OPTS% %LOGGING_CONFIG%
To:
set JAVA_OPTS=%JAVA_OPTS% %LOGGING_CONFIG% -Xms2560M -Xmx2560M

From the documentation:
-Xmsn
Specify the initial size, in bytes, of the memory allocation pool.
This value must be a multiple of 1024 greater than 1MB
-Xmxn
Specify the maximum size, in bytes, of the memory allocation
pool. This value must a multiple of 1024 greater than 2MB.
So maybe you are trying to specify 2.5 GB, but you've really specified
2.5 KB. This isn't going to work.
Try the following in setenv.bat:
set "CATALINA_OPTS=-Xms2560m -Xmx2560m"
. . . . just my two cents.

You need to set CATALINA_OPTS.
