WHY?

22 November 2017 5

Client reproduces error at will on test system Finastra Support team reproduces error at will on Finastra system Finastra Development team fixes the error

Error solving workflow

Finastra |

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 Finastra Development 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.

DYNAMIC TRACE COMMAND LINE

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

Loan IQ DiagnosticTools_Overview_Guide.pdf

Let’s look at a sample config.

VISUALVM

Provides basic thread & memory analysis options Snapshots Similar to Mission Control.
