Wildfly and JVM arguments

[Craig Greenhalgh]

Hi,

I dont think the property is being placed at the correct place, as it wont allow me to override the memory settings.

I use the property

<cargo.jvmargs>-ms512m -mx2G</cargo.jvmargs>

...and this get picked up, however it looks like cargo is also setting some default settings ?  In my boot log I have :


2015-08-25 13:02:16,606 DEBUG [org.jboss.as.config] (MSC service thread 1-7) VM Arguments: -Xms512m -Xmx2G -Xms128m -Xmx512m -D[Standalone] -Dorg.jboss.boot.log.file=.....

My properties are being used, but look like they are being overriden by some defaults (-Xms128m -Xmx512m) as they are placed after mine.  Where are these defaults set ?  They are different to those in the standalone files.

Is this as intended, or is this a bug ?

If this is intended, how can I override the memory settings for the Wildfly server

Thanks for your help

Craig

Hi Craig

I think you have a typo - The corrent cargo.jvmargs to use is with -Xmx and -Xms

Maybe you can send your pom.xml?

Hi many thanks for your help,

Im not sure its a typo in the cargo property name as it is getting picked up (shown in the wildfly logs)

The specific properties are:

        <jboss.host>localhost</jboss.host>
        <jboss.port>82</jboss.port>
        <jboss.jvmargs>-ms512m -mx2G</jboss.jvmargs>

The plugin is defined as:

Hi Craig

Yes, you have a typo. The correct syntax for JVM arguments would be:

-Xms512m -Xmx2g

This is actually the Oracle Java non-standard options, but is supported as is by almost all JVMs: https://docs.oracle.com/javase/8/docs/technotes/tools/windows/java.html#BABHDABI

Hope this helps
