New SOA Diagnostics Tool – IWS Reports – Overview by Malkit

 

clip_image002Introduction

Among many new features added for 12.2.1 version of Oracle Fusion Middleware (announcement link) and demoed at this year’s recently concluded Oracle Open World, I’m particularly excited about brand new diagnostics feature of Oracle SOA Suite called IWS Reports – being the lead designer and implementer of this project.

IWS stands for Integration Workload Statistics and is intended to provide Oracle DB AWR like diagnostics for SOA applications. At high level, IWS can help user with two common challenges faced in SOA:

1 – Scaling Issue

2 – Performance Bottlenecks

Diagnosing performance and scalability issues in SOA can be hard. Performance of a system depends on number of factors. SOA Systems pose particular challenge since large installations typically involves interactions between partners and services – internal and external, stateful and stateless components, synchronous and asynchronous communications, deployment over multi-domain clusters etc.

Main causes for performance/scalability issues:

  1. Insufficient resources – CPU/Memory/network bandwidth
  2. Improper configurations – thread pools/data-sources etc.
  3. Slow partners
  4. Slow database (back-end)
  5. Lower stack (such as application server or operating system) performance issues

The above causes can manifest in following:

  • Lower overall throughput
  • Large increase in response time
  • Backups in global queues
  • System stuck in extreme cases
  • Random errors/non-deterministic behavior (extreme low memory situations)

IWS Reports provide variety of statistics such as system resource usage, message flows at key points in the system, backlogs at various components and activity execution times which can diagnose performance/scaling issues.

IWS in nutshell

  • Helps in identifying bottlenecks and/or backups in the system
  • Useful for tuning for scaling or performance improvement
  • Snapshot based (configurable)/Automatic 
  • Central – collects stats from components and bindings/adapters in single output
  • Lends top-down/outside-in or direct analysis
  • Statistics maps to user application/project environment
  • Single point filtering based on Application/Composite/Component
  • Adds very little memory/processing overhead. Can be left always-on in production systems (off by default)
  • Snapshots persisted – for historical analysis/bench-marking/baseline and snapshot comparison

Note that there are two patents pending around concepts of diagnostics and backlog calculations as used in IWS Reports.  Read the complete article here & part 2 here & part 3 here & part 4 here & part 5 here

SOA Diagnostics in 11.1.1.6

What tools are available for diagnosing SOA Suite issues?
There are a variety of tools available to help you and Support diagnose SOA Suite issues in 11g but it can be confusing as to which tool is appropriate for a particular situation and what their relationships are. This blog post will introduce the various tools and attempt to clarify what each is for and how they are related. Let’s first list the tools we’ll be addressing:

This overview is not mean to be a comprehensive guide on using all of these tools, however, extensive reference materials are included that will provide many more details on their execution. Another point to note is that all of these tools are applicable for Fusion Middleware as a whole but specific products may or may not have implemented features to leverage them. A couple of the tools have a WebLogic Scripting Tool or ‘WLST’ interface. WLST is a command interface for executing pre-built functions and custom scripts against a domain. A detailed WLST tutorial is beyond the scope of this post but you can find general information here. There are more specific resources in the below sections.
In this post when we refer to ‘Enterprise Manager’ or ‘EM’ we are referring to Enterprise Manager Fusion Middleware Control. read the full blog post here.
