Hello,
Is this a bug or am I doing this wrong ?
I'm not totally sure what you're asking about, but I have found that
tomcat7w does not always reflect the current settings if you have made
changes. IIRC, I usually need to restart it to get it to pick up
changes. The other option is to look in the registry for the values;
the changes will appear there by hitting Refresh.
I'm am looking at the registry keys and they are not changing. If I use
tomcatw.exe and make the change to max mem then I see the registry
change to reflect the
change I make in the interface.
But I need to configure this via command-line !
I don't think you can start a service from the command line with
different options from what are already stored in the registry. ISTM
this would be a big security problem.
However, with some utility programs, you can change service settings
from the cmd line before starting it with a "net start..." command.
If you read down this thread, I'm just trying to change the memory from
the command line using the Tomcat tools and it does not work.
I see that, but you're doing it for a service, and apparently trying to
do it from a command line. I just don't think that's possible with the
current tools.
Thanks again,
Pat

I'm trying to change the max memory (java heap -Xmx) using
Tomcat's //US// switch. I type it according to the Windows service
how-to. We would like to script this into our Tomcat deployment
script which right now simply installs the service using "service
install".
With the service already installed I tried the following command
line options:
tomcat7.exe //US//tomcat7 --JvmMs=512 --JvmMx=1024
Hmm.
tomcat7.exe //US//tomcat7 --JvmOptions -Xms512m -Xmx1024m
Although I get no error, I know its not taking because after
starting tomcat.exe I look in the Windows process manager and it
shows its only using 50MB of ram instead of 512MB of ram (the -Xms
value)
Silly question: how do you start Tomcat? (tomcat.exe does not
exist).
It's a Windows service. While testing this I'm just using the
Services
Control Manager to stop and start the service.
Any help would be greatly appreciated.
You didn't follow the instructions for --JvmOptions:
http://tomcat.eu.apache.org/tomcat-7.0-doc/windows-service-howto.html
I did follow the instructions. There are options for *just* min/max
heap size (JvmMS & JvmMx)
You want:
- --JvmOptions -Xms=512#-Xmx=1024
No, this did not work.
After you do either of your commands, what do you see if you do:
C:\> tomcat7w.exe //ES//tomcat7
I'm just launching tomcat7w.exe in Windows and checking the Java tab
to see if it took.
That should show you the current configuration (and let you edit
everything if you want).
Remember that you are only editing the service definition: you will
have to launch Tomcat via the service if you want that configuration
to take effect. Also, if Tomcat is running when you change the
configuration, you'll have to restart the service to notice any
change.
