Monitoring andPerformance Tuning

Oracle E-Business SelfService Transactions

John Spirko

Product Manager,Oracle E-Business Solutions


2/34

Agenda Introduction

Oracle E-Business Transaction Overview 9iAS Architecture Overview

Apache Web Server

9iAS Business Logic Services 9iAS Presentation Services

Web and Database Caching

Common issues How Quest helps

Next Steps and Conclusion


3/34

Introduction Audience

No need to be an expert, just understand basicApplication Server and database concepts

Motivation Maximizing the Performance of theOracle E-Business Suite Ahmed Alomari

Multiple customer visits

Purpose Deliver a high level overview of the Oracle

Application Server architecture Set the stage for a more in depth follow-on paper onconfiguration and common pains with the OracleApplication server

Introduce the Quest APM Suite for Oracle E-Business


4/34

Oracle E-Business Transactions Forms also called Fat Client

Runs in an applet on the desktop Supported by 9i Application Server

Concurrent Manager Back-end transaction runs in batch

Scheduled or on demand

Direct Access Noetix, Oracle Discover, Excel

Self-Service or Thin Client Runs in the clients web browser

No client side software required

Uses mostly Java and XML technology


5/34

9iAS REL 1 Architecture


6/34

Apache Architecture


7/34

Apache Process Control Process

Creates and destroys worker processes based on load demandfrom requesting clients and Apache configuration parameters

Worker Processes Processes that render HTML results back to the requesting

clients Apache API layer

Gives Apache worker processes the ability to performfunctions outside of normal html processing

Apache Mods Works in phases like authentication, logging, content, etc

Phases can be passed to a mod through the API layer

Mod handles the request and passes results back to the

worker


8/34

Apache Web Server Latest version certified with 11.5.9 is

1.3.19

First process pool in a series of pools thatneed attention within 9iAS

Important files httpd.conf (default)

error_log

Access_log


9/34

Business Logic Services Framework for development

Standardizes security and presentation

OA Framework 5.7 latest with 11.5.9

Mostly XML and Servlets The future of Oracle E-Business Suite

Heading towards J2EE with 9i REL 2


10/34

Business Logic Services Oracle BC4J

Business components for Java

Framework for Oracle E-Business Businessintelligence

Eventually should be replaced by OC4J in 9iAS REL 2 Oracle 8i JVM

Java Beans

PLSQL Corba

100% pure Java


11/34

Business Logic Services Oracle 8i PLSQL

Framework for running PLSQL against an Oracledatabase

Oracle Forms

Driving technology for the Full-Service transactiondescribed earlier


12/34

Presentation Services Technology that runs the Business Logic

services Each of the Presentation Services relates

to a Business Logic Service Code base in Business Logic

Enabling technology in Presentation Services


13/34

Presentation Services Apache Jserv

Sun designed servlet processing engine runs servletcode from BC4J and 8i JVM

Oracle JSP

Engine that processes and runs Java Server pages Interprets Java embedded in XML

Extends traditional JSP developed by Sun

Better GC and platform portability

OraclePSP


14/34

Presentation Services Oracle PSP

Similar to Oracle JSP except the interpreterprocesses PLSQL instead of Java

Perl Interpreter

Processes Perl code for calling mod

OraclePSP


15/34

Oracle Web and DB Cache Web Cache

Used for application with a lot of static pages thatoccur in transactions

Common for iStore

Not used across the board

DB Cache Used to store data on mid-tier to minimize database

call

Cached table data instead of web pages This feature has been discontinued as per Oracle

Metalink note: 171517.1


16/34

Top Pains Many areas to cover

Multiple processes

Multiple log files

Multiple configuration files

Two pains for this paper Isolating response time issues

Managing the DB connection pool


17/34

Isolating Response Time Issues


18/34

Response Times using Oracle SQL Tracing

Custom Profile

FND Diagnostics

Response times on Application Server

Oracle DMS

Gives Servlet response times

Gives Mod response times


19/34

SQL Tracing Custom Profile Alter the initialization SQL Statement Custom profile

option for the user you want to trace

Begin fnd_ctl.fnd_sess_ctl('','','TRUE','TRUE','LOG','ALTERSESSION SET EVENTS='||''''||'10046 TRACE NAMECONTEXT FOREVER, LEVEL 12'||''''); end;


20/34

FND Diagnostics

Adds additional button

Must set in profile


21/34

Getting Results $ORACLE_HOME/admin/[DB SID]/udump

$ ls -ltr to see latest log files FND_DIAGNOSTICS will show PIDs

$ ls -ltr | grep 18667

Oracle DMS Dynamic Monitoring Service

Keeps cumulative response times [Home Page]:[Port]/dms0/Spy

[Home Page]:[Port]/servlet/Spy


23/34

Database Connection Pool Database pool managed by OA_Framework

[Home_Page]:[Port]/OA_HTML/jsp/fnd/AoljDbcPoolStatus

Must write script to baseline high-watermark for active JDBC Connections

Pool has been know to run away for many

different reasons Sometimes know to hit max_sessions limit

in Oracle database


24/34

Servlet in later 11i releases
