WHY?
22 November 2017 6
Valid principle… but hard to follow at times:
Client reproduces error
at will on test system
Finastra Support team reproduces
error at will on Finastra system
FinastraDevelopment team fixes the
error
Random issues (one-off or intermittent)
Issue happens on one system (e.g. production) but not on others
Performance issues
Finastra |
WHY?
DIAGNOSTIC TOOLS
Provide enhanced logging and tracing
Can be used by client and/or Finastra
More efficient than remote diagnostic connections
Less deployment problems
Less problems with internal security policies
Re-usable diagnostic scripts across multiple Loan IQ versions (Loan IQ Dynamic Trace, JMeter)

MAIN TOOLS
Apache JMeter
Both the Client and the Finastra support can use JMeter, but the majority expected is from Finastra Support. This is generally used for load performance (that is, API) or Online SQL issues (Example: Circle close).
Java VisualVM
Both the Client and the Finastra support can use VisualVM, but the majority expected is from Finastra Support. This is a useful tool used for reporting performance issues such as memory usage.
Java Mission Control (JMC)
Both the Client and the Finastra support can use JMC. Use Flight Recorder to report relevant issues around delayed response, performance and it is good for snapshots during issue re-creation.
Do you need a license?
Loan IQ Dynamic Tracer
Btrace will be used by Finastra Support and the scripts will be supplied during analysis of issues, if needed, as alternative to the debug jars. This tool is used to add debug code to help identify bugs. The Scripts are compiled into bytecode and submitted to the Loan IQ runtime.

DYNAMIC TRACE & ATTACH API
The Attach API is an extension that provides a mechanism to attach to a Java virtual machine.
A tool written in the Java Language, uses this API to attach to a target virtual machine and load its tool agent into that virtual machine.
Our scripts are referred to as DynamicTrace scripts.

Our preferred method for DataFix program data analysis.
DataFix attempts to diagnose categorised data corruptions such as Object states being incorrect.
