Chapter 12. Troubleshooting
Techniques
Application platforms such as SOA Suite go through various issues during design, de-
ployment, and runtime. In this chapter, our primary focus is to learn the troubleshoot-
ing techniques for commonly-found issues of a composite application deployment and
runtime with the Oracle SOA Suite BPEL Process Manager. Usually, SOA composite
applications runtime health depends on external service's endpoints and user activit-
ies. Therefore, runtime issues may pop up without any changes in the software and
the systems managed within your organization but maybe due to the increased user
activities, external updates, and/or network issues.
The following diagram shows the BPEL composite application technology stack.
The troubleshooting requires knowledge in different components within the stack for
resolving BPEL composite application issues.
JVM issues
The Oracle SOA Suite application runs within a
Java Virtual Machine
(
JVM
). There-
fore, the following JVM-related issues can happen with your SOA composite applica-
tion platform:
•
JVM crash
: This is a rare issue but does happen in some deployments.
Please ensure that you have got the correct and Oracle SUN certified Java
binaries for your server platform. Even a small mismatch can cause the
JVM to crash.
•
OutofMemory errors and Memory leaks
: If the initial deployment throws
OutOfMemory errors then go ahead and tune the JVM size as discussed
in
