RedHat 5.6 64-bit
"java -version" output:
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01, mixed mode)
Tomcat: 6.0.26
The "-d64" option seems to be removed from the "ps" command line arguments:
I added a "set -x" to $CATALINA_HOME/bin/catalina.sh so that I could see
the actual java invocation:
+ /path/to/jdk1.6.0_20/bin/java
-Djava.util.logging.config.file=/path/to/logging.properties -d64
-Xms3072m -Xmx3072m (...various app specific -D options...)
-Djava.awt.headless=true
-Dorg.xml.sax.driver=org.apache.xerces.parsers.SAXParser
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.endorsed.dirs=/path/to/apache-tomcat-6.0.26/endorsed -classpath
/path/to/apache-tomcat-6.0.26/bin/bootstrap.jar
-Dcatalina.base=/path/to/tomcat
-Dcatalina.home=/path/to/apache-tomcat-6.0.26
-Djava.io.tmpdir=/path/to/tomcat/temp
org.apache.catalina.startup.Bootstrap start
When I do a "ps aux" I see this:
/path/to/jdk1.6.0_20/bin/java
-Djava.util.logging.config.file=/path/to/logging.properties -Xms3072m
-Xmx3072m (...various app specific -D options...)
-Djava.awt.headless=true
-Dorg.xml.sax.driver=org.apache.xerces.parsers.SAXParser
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.endorsed.dirs=/path/to/apache-tomcat-6.0.26/endorsed -classpath
/path/to/apache-tomcat-6.0.26/bin/bootstrap.jar
-Dcatalina.base=/path/to/tomcat
-Dcatalina.home=/path/to/apache-tomcat-6.0.26
-Djava.io.tmpdir=/path/to/tomcat/temp
org.apache.catalina.startup.Bootstrap start
Where did the "-d64" option go?
I'm pretty sure that this is OK and that the JVM just modified its
argument line
while using the 64 bit memory model but it still makes me slightly nervous.
