33. HTML Site Deployment

34. Identify Document Root

35. 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

36. Run the web app…

37. 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

38. 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

39. OEM System Components

40. 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

41. 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.

42. Deploy a PL/SQL Application
Requires Database Access Descriptor (DAD) configuration
PL/SQL packages, procedures in the database using web toolkit

43. Sample Stored Procedure
In a schema, create a stored procedure:
connect scott/tiger
create or replace procedure hello_oracle is
begin
htp.print ('<h1>Hello oracle</h1>');
end; /
Setup a tnsnames.ora entry if one does not exist in middle tier to target database

44. Define the DAD in OEM Access the middle tier instance
Click ‘HTTP Server’
Click ‘PL/SQL Properties’ under Administration
Click ‘Create’ in DAD Status

45. 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

46. Run the PL/SQL App (con’d)
Run the url:

47. Troubleshooting

48. Troubleshooting 9iAS rel2
I can’t connect!

49. Troubleshooting
Can you connect from your browser to the middle tier http server?
Is network connectivity available to the server? ‘ping servername’
Does sql*net connectivity exist between the middle tier and infrastructure?

50. Troubleshooting Is Oracle Internet Directory running?
$ ps -ef | grep oid
oracle Oct 04 ? :05 /d01/oracle/product/9ias_infra/bin/oidmon start
oracle Oct 04 ? :07 oidldapd -p i 1 -conf 0 –s port sslenable 2 key=
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

51. Win2K Services Panel
Are your middle tier and infrastructure services running?

52. 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

53. Using RDA (continued)

54. 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

55. Review Error Logs Infrastructure from $ORACLE_HOME:
./Apache/Apache/logs/error_log
./ldap/log/*
./sysman/log/*
./opmn/logs/ons.log
./opmn/logs/ipm.log
