   set "JAVA_OPTS=-Xms1303m -Xmx1303m -XX:MaxPermSize=256m -Dorg.jboss.resolver.warning=true -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Dsun.lang.ClassLoader.allowArraySyntax=true"

   • Memory argument for 32-bit JVM:

      set "JAVA_HEAP_ARGS=-Xms1024m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=192m"

   • Memory argument for 64-bit JVM:

     set "JAVA_HEAP_ARGS=-Xms1024m -Xmx2048m -XX:PermSize=256m -XX:MaxPermSize=512m -XX:+UseCompressedOops"

3. Add the following line.

   set "JAVA_OPTS=%JAVA_OPTS% %JAVA_HEAP_ARGS%"

4. Add the following argument for 32-bit and 64-bit JVM:

5. (Optional) Modify JBoss Application Server to run in IPv6 mode as follows:

   • Locate and modify -Djava.net.preferIPv4Stack=false

   • Insert the string-Djava.net.preferIPv6Stack=true

   Note: If the application server log contains the following error on startup, remove the value for the IPv6 stack and set the IPV4 value back to true:

   “13:37:44,488 WARN [HANamingService] Failed to start AutomaticDiscovery java.net.SocketException: bad argument for IP_MULTICAST_IF: address not bound to any interface at java.net.PlainDatagramSocketImpl.socketSetOption(Native Method)at java.net.PlainDatagramSocketImpl.setOption(PlainDatagramSocketImpl.java:260)”

6. Save and close the file.

Solaris JDKs from Sun require an additional argument to use 64-bit features. Without this configuration change, the Sun JDK defaults to 32-bit support only.

1. Open the [appserver root]/bin/run.conf file in an editor.

2. Locate the section starting with:

   if [ "x$JAVA_OPTS" = "x" ]; then

   Modify the section to look like:

   if [ "x$JAVA_OPTS" = "x" ]; then 
      #JAVA_OPTS="-Xms1303m -Xmx1303m -XX:MaxPermSize=256m -Dorg.jboss.resolver.warning=true -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Dsun.lang.ClassLoader.allowArraySyntax=true"

       JAVA_OPTS="$JAVA_OPTS -Dadobeidp.serverName=server1 -Dfile.encoding=utf8 -Djava.net.preferIPv4Stack=true" 
       JAVA_OPTS="$JAVA_OPTS -DentityExpansionLimit=10000" 
       JAVA_OPTS="$JAVA_OPTS -XX:+UseCompressedOops -XX:+HeapDumpOnOutOfMemoryError"

   Note: Ensure that this entry appears as a single line in the run.conf file.

3. (optional)Modify JBoss Application Server to run in IPv6 mode as follows:

   • Locate and modify -Djava.net.preferIPv4Stack=false

   • Add -Djava.net.preferIPv6Stack=true

3. Locate the Limit categories section and add the following:

   <category name="jacorb.config"> 
   <priority value="ERROR"/>

   <category name="com.adobe"> 
       <priority value="INFO"/> 
   </category>

   </category> 
   <!-- Limit the verbose MC4J EMS (lib used by admin-console) categories --> 
   <category name="org.mc4j.ems"> 
   <priority value="WARN"/> 
   </category>

4. Save and close the file.

1. Ensure that transaction management works as expected by locating the jbossts-properties.xml file in the [appserver root]/server/<profile_name>/conf directory and opening the file in an editor.

2. Locate and modify the properties element as follows (modification in bold). Add the property in bold if it doesn’t already exist in the jbossts-properties.xml file.

   <properties depends="arjuna" name="jta">  
   <property name="com.arjuna.ats.jta.allowMultipleLastResources" value="true"/>  
   <!-- ... other properties ... --> 
   </properties>

3. If you are not using messaging, locate and comment out following lines

   <property name="com.arjuna.ats.jta.recovery.XAResourceRecovery.JBMESSAGING1"value="org.jboss.jms.server.recovery.MessagingXAResourceRecovery;java:/DefaultJMSProvider"/>
