After few releases
There is bug in Production. I am not sure which
version of source is running in Production!!!!!

8
Build Process

• Developer send the EAR file to deployer in email
  or in copies on a share

9
Automated build Process

• Extract Source from Version Control System
• Compile the code using automated scripts
• Package the code

10
Advantages of Automated Build

• Enforce Standards
• Consistent use of Third-party and Java Compilers
• Can locate any version of EAR
• Faster builds and process driven builds

What is deployment

• Install the package the EAR file
• Change the configuration of the application

In Summary

• JNDI names for the EJBs
• JNDI mapping to ejb-refs and res-refs
• Virtual Host mapping to web-module

Deployment Communication Process
How will I get the config info?
How do I tell the deployer?
20
Deployment Communication Process Attempt 1
Well done
Why tell? I have all configs in EAR correct
21
After few drop, app become complicated Attempt
1 fails
Oops!! One of our developers has miss configured
an existing JNDI name
Oh! You are using wrong DS JNDI and affecting
other apps
22
Deployment Communication Process Attempt 2
Good man
Brilliant idea!
Send him a document
23
After few deploys using document Attempt 2 fails
I hope it works
I hope he deploys it correct!!
24
Need to be repeatable
25
Disadvantages of Trusting Developers
Documentation

• Time Consuming
• Error Prone
• Tedious
• Non Repeatable
• Risky

26
Now what
Yeah right! Jython is complicated
Lets automate it
27
Introduction to Slick-Deploy

• Open Source - free
• Generic XML based
• ANT based
• Easy!!

28
What can Slick Deploy do

• Stop writing Documentation
• Create an XML file deploydata.xml

Environment Configuration

• Create a Build and Deploy Server
• Install the WebSphere Client
• Install ANT and your ANT Scripts
• All the apps to all WAS boxes are deployed from
  here

Where do I install SlickDeploy?
35
Deployment Server Push Approach
Deploy ANT Script
SD Ant jar
Deploy
WAS Client
WAS Dep Manager
SD Deploy jar
36
Deploydata location

• In version control system with your EAR file
  versioned together

Where to keep DD.xml

Deploy EAR Process

• earFileLocation"c/ear/Trade3.ear
• deployDataLocation"c/deploydata/Trade3-deploydat
  a.xml" /

40
Deploy ANT Task

• applicationName"Trade3"
• cell"MyCell01" port"8889" host"MyHost"
• cluster"Test-CL
• earFileLocation"c/SlickDeploy/ear/Trade3.ear
• deployDataLocation"c/Trade3-deploydata.xml"
• userName"wasadmin" password"wasadmin"
• failIfResourceAbsent"No" webserver"IIS"
  connectionType"SOAP" /

42
DDCreater

• Pass the location of EAR file.
• Pass the location where deploydata.xml file
  should be created.

Do I have to write the deploydata
43
What do the deployers feel?
Wow! Just answer a few questions and sit and
watch the deployment progress!!!
44
Why automate?

• Repeatable deployment without manual
  intervention.
• No manual error.
• Reduce deployment time of application by 50.
• Reduce the human resource required for deploying
  the application.
• Reduce the amount of documentation developers and
  deployers need to produce and hence technical
  staff can concentrate on technical work.

But I still have to create the resources, Servers
etc. What about that?
