JDK 1.6.0_43 64 Bit 無法使用 jvm snmp

JDK 1.6.0_43 64 Bit 無法使用 jvm snmp ,一定要使用檔案的方式宣告方可使用.
之前使用直寫的方式,在 java 32 Bit 的版本是沒問題的.

另外一個問題是 /etc/hosts 一定要將主機名稱寫入,要不然 jmx 是無法使用
-Djava.rmi.server.hostname=192.168.x.x 這個參數!

java snmp 以檔案方式宣告如下:

tomcat startup.sh

export JAVA_OPTS="-Xms1024m -Xmx1024m  -XX:PermSize=128m -XX:MaxPermSize=256m -Dcom.sun.management.config.file=/usr/local/tomcat/bin/snmp.properties -Dcom.sun.management.jmxremote -Djava.rmi.server.hostname=192.168.x.x. -Dcom.sun.management.jmxremote.port=9012 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false"


[root@Test-Tomcat bin]# cat snmp.acl
acl = {
  {
    communities = public
    access = read-only
    managers = localhost
  }
}
[root@Test-Tomcat bin]# cat snmp.properties
com.sun.management.snmp.interface=0.0.0.0
com.sun.management.snmp.port=1610
com.sun.management.snmp.acl=/usr/local/tomcat/bin/snmp.acl


直寫方式如下:

export JAVA_OPTS="="-Xms1024m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=256m -Dcom.sun.management.jmxremote -Djava.rmi.server.hostname=192.168.xx.xx -Dcom.sun.management.jmxremote
.port=9012 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.managemen
t.snmp.port=1610 -Dcom.sun.management.snmp.acl.file=/tmp/snmp.acl -Dcom.sun.management.snmp.interface=0.0.0.0"

# When loaded, the mod_proxy_ajp module adds support for

# proxying to an AJP/1.3 backend server (such as Tomcat).

# To proxy to an AJP backend, use the "ajp://" URI scheme;

# Tomcat is configured to listen on port 8009 for AJP requests

# by default.

 

# Uncomment the following lines to serve the ROOT webapp

# under the /tomcat/ location, and the jsp-examples webapp

# under the /examples/ location.

#ProxyPass /tomcat/ ajp://localhost:8009/

#ProxyPass /examples/ ajp://localhost:8009/jsp-examples/
