OOW - Day 4 - The final session - Oracle Enterprise Manager - Custom Application Management

In this session we will have more insight in the different features available in Oracle Enterprise Manager to deploy custom applications.

Key message:

• Use out-of-the-box models to represent your services
• Monitor your applications from end-user perspective (pro-active and passive)
• Monitor your application specific metrics => expose via JMX and Web Services
• Build reports

What is a custom application?

• J2EE Applications
• Applications exposing metadata via JMX or Web Services
• Oracle Forms Applications
• Web-based applications (.net, php)

1a. EM Feature: Pro-active monitoring :

In pro-active monitoring you’re tracking the known transactions for your application.

• Web transactions: intuitive recorder => playback transactions from Beacon (EM agent)
• Forms transactions: intuitive recorder for Forms 10.1.2, 9.0.4 and 6i applications
• Generic service tests: to test any protocol-based services

1b. EM Feature: End-user monitoring:

In end-user monitoring you don’t know which transactions will get launched, so you need to listen for them.

Passive end-user monitoring:

• Watch URL Response times => by domain, region, visitor, web server
• Forms 10.1.2 => commit, query, runform, callform, newform

2. Service-level dashboard: monitoring of SLA’s

3. Application Diagnostics for Java (AD4J):

An agent running on the application server to diagnose Java Applications.

• No performance overhead and instrumentation complexity of BCI based tools
• Transaction tracing capability => java transactions through db sessions and vice versa
• Oracle, non-Oracle, Java Servers & Standalone Java Applications

4. Infrastructure diagnostics:

• Historical views and trends
• Monitoring templates
• Alerts, notifications

5. Management Plug-in:

Extend Enterprise Manager functionelity for custom components using Management Plug-in.

How to create a management plug-in:

1. Define metrics to collect and tresholds
2. Develop metadata file (in XML file) to declare metrics, associate scripts
3. Validate using ILINT
4. Package in management plug-in archive (MPA)

How to create management plug-in for Web Services, JMX:

1. Run CLI (Command Line Utility) JMX or Webservice
2. Package Management Plug-in Archive

6. Custom Application Monitoring:

• Out-of-the-box homepage for all custom applications
• No need to write UI code
• Provides consolidated view of availability and alerts
• Reporting available using PL/SQL API

For more information there’s an Oracle By Example available on OTN.
