Installing 9i Application Server

Installation Options

• Oracle 9iAS Infrastructure (includes):– Repository Database (9.0.1.3)– Oracle Internet Directory (LDAP) server– Single Sign-On – HTTP Server

• 9i Application Server (Middle Tier)– Runs all 9iAS release 2 applications– Many applications connect to infrastructure

• 9iAS Developer Kits

Middle Tier Installation Options• Infrastructure Not Required:

– J2EE and WebCache

• Infrastructure Required:– Portal and Wireless– Business Intelligence and Forms

• Discoverer Plus/Viewer• Forms and Reports

– Unified Messaging

Managing 9iAS Release 2

Managing with Enterprise Manager• Secure, graphical interface

• Performance metrics for all 9iAS components

• Wizard-based component configuration

• Access to error logs

Oracle Enterprise Manager

Managing the HTTP Server

Key URLs

• Oracle Enterprise Manager http://servername.com:1810

• HTTP Server (midtier and infrastructure)– http://servername.com:port– Default unix midtier: http://servername.com:7778– Default unix single-sign on (infrastructure):

http://servername.com:7777

• Verify Installation with Demos: http://servername.com:port/iASDemos.htm

• Single Sign-on http://servername.com:port/pls/orasso

• Portal http://servername.com:port/pls/portal

Key Configuration Files

• ./Apache/Apache/conf/httpd.conf– Contains HTTP Server directives – Main Configuration File– Three sections of the httpd.conf file:

• Directives that affect all http server processes and installation

• Directives that define the default apache server process• Virtual hosts (running multiple web sites from single http

server)

• ./Apache/modplsql/conf/dads.conf– Contains database access descriptor information for

mod_plsql applications including portal. – Modified through OEM or manually.

Using the DCMCTL utility

• Distributed Configuration Management (DCM)

• Can be used alternatively to OEM– Starting/Stopping– Registering new applications– Managing components

• Documented in Oracle9i Application Server Administrator's Guide Release 2

Stop the Middle Tier

Stop the Middle Tier

• Step 1: Stop Middle Tier components:– From OEM, click ‘middle tier instance’, click

‘Stop All’– Unix: from a command prompt, verify that

all processes in the middle tier have stopped.$ ps –ef | grep _apps

– Win2K: Verify that all middle tier services have stopped.

• Step 2: Stop Infrastructure components:– From OEM, click ‘infrastructure’ instance,

click ‘Stop All’– Unix: from a command prompt, verify that

all processes in the middle tier have stopped.$ ps –ef | grep _infra

– Win2K: Verify that all middle tier services have stopped


• Step 3: Stop OID – If OID is still running, use the following

commands to stop OID:$ oidctl server=oidldapd instance=1 configset=1 stop

$ oidmon stop Monitor Process Terminated

• Step 4: Stop Enterprise Manager$ emctl stop


• Step 5: Kill any remaining processes

• Step 6: Stop TNS listener$ lsnrctl stop

Applications are deployed to middle tier

HTML Site Deployment

Identify Document Root

Deploying an html web site

• Create a subdirectory below ‘document root’ of middle tier application server

• Copy all application html and image files to new directory.$ mkdir MyNewApp$ cp index.html ./MyNewApp$ cp *.html ./MyNewApp

Run the web app…

Create a Java App

• Developers build an application using JDeveloper or other Java development tools

• Developers may package the application to:– .ear file [Enterprise ARchive] – J2EE

Packaged Application. May contain XML, .java, .war files, classes

– .war file [Web ARchive] – Packaged JSPs and Servlets

Deploying a Java App (using a WAR file)

• In OEM, select middle tier instance

• Click ‘Create OC4J Instance’

• Add ‘Instance Name’• Click ‘Create’• New OC4J app will

appear in the System Components list of middle tier

OEM System Components

Deploy WAR (con’d)• Enter path to

WAR file or use the Browse button

• Enter Application Name

• In “Map to URL” Enter a virtual path (i.e. MyDemo)

• Click Deploy

Deploy Java App (con’d)

• Receive success message• During deployment WAR files are ‘wrapped’ to

EAR files before deployment• You are returned to administration screen in

OEM for your application.• Click ‘Start’ to start the OC4J application• You can then run the application from the

browser: (i.e. http://www.yourdomain.com:7778/MyDemo)

Deploy a PL/SQL Application• Requires Database Access

Descriptor (DAD) configuration

• PL/SQL packages, procedures in the database using web toolkit

Sample Stored Procedure• In a schema, create a stored procedure:

connect scott/tigercreate or replace procedure hello_oracle isbegin htp.print ('<h1>Hello oracle</h1>');

end;/

• Setup a tnsnames.ora entry if one does not exist in middle tier to target database

Define the DAD in OEM

• Access the middle tier instance

• Click ‘HTTP Server’

• Click ‘PL/SQL Properties’ under Administration

• Click ‘Create’ in DAD Status

Define the DAD in OEM (con’d)• Step 1 – Create

DAD: DAD Type

• Portal or General

• Step 2 – Username, password, connect string

• Authentication Mode = Basic

• Finish & Restart HTTP Server

Run the PL/SQL App (con’d)• Run the url:http://www.yourdomain.com:7778/hello_oracle/

hello_oracle

Troubleshooting

Troubleshooting 9iAS rel2

I can’t connect!

Troubleshooting

• Can you connect from your browser to the middle tier http server? http://hostname:port/

• Is network connectivity available to the server? ‘ping servername’

• Does sql*net connectivity exist between the middle tier and infrastructure?

Troubleshooting

• Is Oracle Internet Directory running?$ ps -ef | grep oid oracle 21914 1 0 Oct 04 ? 0:05 /d01/oracle/product/9ias_infra/bin/oidmon

start oracle 21979 21914 0 Oct 04 ? 0:07 oidldapd -p 4032 -i 1 -conf 0

–s port 4031 -sslenable 2 key=1436210937

• Can you connect to the infrastructure database?– Attempt a client/server connection to the

database verifying the listener is listening for incoming requests

– Connect to the database using sql*plus

Win2K Services Panel

• Are your middle tier and infrastructure services running?

Using RDA

• Remote Diagnostic Agent from Oracle Support – Gathers Oracle environment information– Gathers hardware and operating system information

• Download RDA from metalink.oracle.com• Set environment to middle tier or infrastructure

$ORACLE_HOME• Run rda.sh script• Unix Tip: Create a directory beneath document

root and copy RDA_OUTPUT files

Using RDA (continued)

• http://servername:port/rda/RDA__START.htm

Review Error Logs

Middle Tier from $ORACLE_HOME :• ./Apache/Apache/logs/error_log• ./opmn/logs/ons.log• ./opmn/logs/ipm.log• ./webcache/logs/event_log• ./webcache/logs/access_log

Review Error Logs

Infrastructure from $ORACLE_HOME:• ./Apache/Apache/logs/error_log• ./ldap/log/*• ./sysman/log/*• ./opmn/logs/ons.log• ./opmn/logs/ipm.log
