er and the JVM, leverage SQL queries to obtain instance specific informa-
tion, use the DMS Spy Servlet to get various runtime values, and have a
thorough understanding of the various server log files.
Chapter 4 , Tuning SOA Oracle Suite 11g for Optimum Performance though
focused primarily on performance tuning, described areas such as when,
how, and why to modify JVM settings, connection pool properties, timeout
values, and other service engine properties.
Chapter 5 , Configuring and Administering Oracle SOA Suite 11g talked
about further configuration and administration of the infrastruc-
ture—everything from JCA binding properties, fault management, configur-
ing timeouts, and overriding resource adapter properties.
With this, you are now armed with the tools and knowledge to troubleshoot any
number of issues. However, before embarking on troubleshooting any issue, you
must at least have some starting point:
Is this an infrastructure issue?
Is this a performance issue?
Is this an issue specific to a single composite or instance?
Is this a deployment issue?
Based on the type of problem, you can somewhat narrow down the troubleshoot-
ing activity. The goal in this chapter is not to walk through all actual errors and
their resolution. You will encounter many examples of errors throughout this
chapter, each and every one of them requiring further investigation. It is not often
the case that you will stumble upon an error and immediately identify its resolu-
tion. Therefore, some of the other approaches you should consider utilizing are:
Perform web searches for your error.
Search within My Oracle Support and the Oracle Technology Network
forums.
Review the multiple log files (for example, soa_server1.out,
soa_server1.log , and soa_server1-diagnostic.log) .
Increase logging to get more information about the error.
Engage Oracle Support.
