4. Save and close the file.

1. Open the [appserver root]/server/<profile_name>/deployers/ejb-deployer-jboss-beans.xml file in an editor.

2. Locate <property name="CallByValue"> and change the value to true.

3. Save and close the file.

4. Open the [appserver root]/server/<profile_name>/deployers/ear-deployer-jboss-beans.xml file in an editor.

5. Locate <property name="isolated"> and change the value to true.

6. Locate <property name="CallByValue">false</property> and change the value to true.

7. Save and close the file.

8. Open the [appserver root]/server/<profile_name>/conf/jboss-service.xml file in an editor.

9. Locate <attribute name="CallByValue">false</attribute> and change the value to true.

10. Save and close the file.

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

2. Add the following lines

   Memory argument for 32-bit JVM:

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

   Memory argument f for 64-bit JVM:

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

   Other argument f for 32-bit and 64-bit JVM:

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

3. (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)”

   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 -Xms1024m -Xmx2048m -XX:MaxPermSize=512m -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

4. Save and close the file.

1. Open the [appserver root]/server/<profile_name>/conf/jboss-log4j.xml file in an editor.

2. Locate the following text in the FILE appender section and add the line/change the value that appears in bold:

   <appender name="FILE" class="org.jboss.logging.appender.DailyRollingFileAppender"> 
       <errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/> 
       <param name="File" value="${jboss.server.home.dir}/log/server.log"/> 
           <param name="Append" value="false"/>

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

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

   </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. 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"/>
