Using / Running / Setting JDeveloper 11.1.1.6 to use 64 bit and 32 bit JVM / JDK

Tired of memory issues while working with JDeveloper because you are running on 32 bit JVM. Switch you JDeveloper to point to 64 bit JVM.This will allow you to use multi Gig memory usage while working with JDeveloper IDE.

Prerequisites: 64 bit Machine, 64 bit OS and 64 bit Jdk Installation. JAVA_HOME should be set to appropriate 64 bit jdk installation directory for example 

JAVA_HOME = C:\Program Files\Java\jdk1.6.0_23
So your JAVA_HOME=C:\Program Files\Java\jdk1.6.0_23

JDeveloper's Settings:

1.  C:\Oracle\Middleware\jdeveloper\ide\bin\ide.conf

• AddVMOption  -Xmx4192M
• AddVMOption  -Xms512M 

Above setting will allows to user 4 GB of RAM.

 

 2. C:\Oracle\Middleware\jdeveloper\jdev\bin\jdev.conf

• Point JDeveloper to use 64 bit Java Version
•  SetJavaHome C:\Program Files\Java\jdk1.6.0_23
• AddVMOption  -XX:MaxPermSize=1024M

Namespace prefix "oraext" qualifying cannot be resolved while Designing BPEL processes in Oracle SOA Suite 11g

SOA Developers mainly encounters this issue while using Oracle Extension functions in the Assign or Transform activities.

This error occurs when namespace is not defined in your BPEL process. check two points here.
1. Is namespace : http://www.oracle.com/XSL/Transform/java/oracle.tip.pc.services.functions.ExtFunc is already defined in BPEL process or not ? if not, Define it as below.
xmlns:oraext="http://www.oracle.com/XSL/Transform/java/oracle.tip.pc.services.functions.ExtFunc"

2. If namespace is already defined in the BPEL process then you need verify the prefix value here.for example below is the entry found in BPEL process.
 xmlns:ns4="http://www.oracle.com/XSL/Transform/java/oracle.tip.pc.services.functions.ExtFunc"

here you need rename the prefix values "ns4" to "oraext".  OR

modify the function name prefix in Transformation with "ns4"
