Host Access Pains
What problems need to be solved?

WebSphere
Host Access Pains
● What pains do you feel when trying to support host access efforts in
your company?

WebSphere
Host Access Pains continued
● Costly to deploy and maintain host access software
● Existing host applications are hard to learn and use
● Speed to the web is critical
● Employee dissatisfaction
● Outdated appearance
● High training costs
● Tedious workflow

WebSphere
Host Access Pains continued
● Information needs to be extended to new end users:
Inside and outside the enterprise
● Rewriting existing applications as web applications:
Time-consuming, costly and risky
Web programming skills are scarce
What can be done to ease the pain?

IBM Software Group
What is HATS?

WebSphere
HATS is a rules-based transformation engine…
● Host Access Transformation Services dynamically transforms host
screens to HTML
out of the box
in real-time
based on rules specified by the developer

WebSphere
What else does HATS provide?
● Quickly convert host applications to Web pages
Without touching the host screen source code!
Immediate results and ROI
No additional cost of software deployment to end user
● Reach new end users
Customers, policy holders, the general public...
● Control over content and user navigation

WebSphere
What else does HATS provide? continued
● Improved appearance, usability and navigation
Reduce transaction times
Reduce training time
Consolidate data from multiple host applications
● Enable standardized application access
Access multiple applications with one authentication challenge
● Streamline the workflow of existing applications

WebSphere
● Build software components
Reusable in Web applications
Web Services to link to new Web applications
Componentize business processes
● Integrate information from multiple applications and databases into
Portals
● Incorporate Java in host application interactions

WebSphere
● Screen Customization
Templates and cascading style sheets
Buttons, hot links, drop-down menus, valid value lists
Modify graphics, fonts, colors, and layout
● Macros & Global Variables
Skip unnecessary screens; combine or split screens
Enter data on behalf of the end user
Store end user input as global variables
Pre-fill text entry fields

WebSphere
Instead of presenting users with “green screens”…

WebSphere
…present host screens transformed into Web pages…

WebSphere
…or present data as portlets in WebSphere Portal…
5250
application
portlets

WebSphere
…or generate host application data as a Web Service
3270
application
data

WebSphere
…or use HATS as the first step to new technologies!
● Java
● JavaScript
● XML
● Struts
● JavaServer Faces
● Enterprise Generation Language
● Etc…
Programmers of RPG, COBOL, PL/I, etc can benefit from developing solutions
using Rational Software Development Platform (RSDP) and HATS, while
learning new technologies.

WebSphere
Rational Software Development Platform and HATS
If it ain’t broke, reuse it
Improve the user interface
No change to host application
Quickly build new applications
Build modular components
Streamline workflow
Early return on investment

…and replace the input fields with a
drop-down menu containing
selections defined by the developer.

WebSphere
Default Rendering: Global Rules Pattern Types
● Find input fields by surrounding text
Can specify text is above, below, left, or right
Optionally case sensitive
Takes wildcards (*)
● Find “All input fields”
Good for testing your transformation fragment
● Find “Nearest input field only”

Global Variables - What are they?
A named location for storing a value...
fruitList appleapple
...which can then be used throughout the lifetime of a session.
or a list of string values
apple
orange
banana
fruitList apple
orange
banana

WebSphere
An indexed global variable has a list of values rather than a single string.
Global variable name
fruitList 0: apple
1: orange
2: banana
3: pineapple
...with 4 values
Indexed Global Variables
Index numbers start at 0.

WebSphere
Each HATS client session is assigned a global variable table.
Client A's
global variable table
Client B's
Client C's
Global Variable Tables
The table is destroyed along
with the rest of the client data
when the session ends.

WebSphere
Global Variable Usage
● Screen Customizations
● Transformations
● Pass data from one object to another
● Pass data to and from Java programs
● Extract and insert text on host screens
● Concatenate text
● Macros
● Tabbed Folders

● Certificate Express Logon
Allows authentication by way of X.509 certificates
● The end user’s X.509 certificate configured in the browser is used as the input
to map network ID to host user ID. This means that the certificate is extracted
from the browser. No NSA involved here, as the X.509 certificate exchange is
the authentication and authorization.
● No JDBC first step to map the user identity to a host ID because the certificate
is sent to DCAS and RACF looks up the user ID and a limited-use password is
generated
● DCAS requires a Security Access Facility (SAF)-compliant server product,
such as IBM RACF, that supports passticket generation.

Performance Considerations

WebSphere
Rational Application Developer Performance Tips
● This article contains a series of hints and tips that you can use to
improve the performance of IBM Rational Application Developer.
Rational Application Developer Performance Tips
http://www-128.ibm.com/developerworks/rational/library/05/517_radtip/

WebSphere
RAD Clean Up: Removing outdated files
Rational® Product Updater can remove from your system any files that
become outdated after you install a new update.
When the Product Updater tool installs an update, previous versions of the
superseded files are not overwritten; they remain on your file system. This is
required in order for Product Updater to be able to roll back the update. However,
this also means that disk space is used to store both the new and previous
versions of files.
To reduce the disk space used by the installed products, you can purge their
outdated files using the Product Updater's Clean Up function.
Important: If you run Clean Up, you will not be able to roll back any of the
currently installed updates for any of the installed products.

WebSphere
RAD Clean Up: Removing outdated files continued
To cleanup outdated files:
Log on to your system with the same user account used to install your Rational
software development product.
Restriction: On Windows® operating systems, this account requires Administrator
privileges. On Linux® operating systems, you must use the root user account.
Start Rational Product Updater:
An inventory of installed products is displayed.
Click Clean Up.
A dialog box warns you that you cannot roll back any of the currently installed
updates after cleaning up. Click Continue.
When the cleanup completes, a message confirming the success of the operation
appears in the top pane of the Product Updater window. The Clean Up button is
disabled, and on Rollbacks page, rollback will be disabled for all updates and
optional features.

● Compression Significantly reduces the number of bytes sent over the
network
● Improves response time
● Supported on WebSphere Application Server 5.1 and WebSphere
Application Server 6.0.
● Not supported when running in WebSphere Portal
● Requires a browser that supports GZIP compression
All supported HATS browsers support GZIP, with the exception of IE 5.2.3
on Mac
● This function does not compress *.js, *.css, or any other static content.
Use Web server compression to compress static content.

WebSphere
Some performance topics from the…
HATS User’s and Administrator’s Guide
● Use Contention Resolution to improve performance and reliability?
● Tune strategy delays?
● What happens when a delay like default.delayInterval is set too small?
● What happens when a delay is set too large?
● Correct other problem scenarios?
● Use the asynchronous update applet?

WebSphere
Contention Resolution (TN3270E only) (RFC2355)
● Contention resolution helps overcome limitations in the conversion of
the SNA protocol of the host, to the Telnet protocol of the clients.
● Using contention resolution improves the performance of TN3270E
clients, including HATS.
● The use of contention resolution is negotiated during connection setup.
● If HATS successfully negotiates contention resolution with the TN3270E
server, communication is more efficient, resulting in fewer delays
interacting with host systems.

WebSphere
Asynchronous Update Applet
● Updates asynchronous outbound host data
Push content to browser when it is not expected, such as blank
screens not normally seen in a standard emulator
● Enhances performance by reducing screen-settling* Signed Java Applet
● Disabled by default; enable in Project Settings
*The process in HATS of analyzing outbound host data and
deciding when to use the current host screen.

WebSphere
Disable the Display Terminal
● Avoid performance degradation:
Right-click on the project in HATS Project View
Click “Open Administration Console”
Click Troubleshooting > Trace Settings
Uncheck “Enable Display Terminal”

WebSphere
Running HATS V6 applications on WAS V6
● Avoid performance degradation
WebSphere Application Server 6.0.0.2 should be the minimum
service level when running HATS applications that repeatedly
execute JSPs which invoke HATS Integration Objects.
(From the HATS V6 Readme)

WebSphere
Disabling the Web Browser’s Back Button
● Using the browser's Back button can cause unpredictable results. You
can disable the Back button by inserting this script into each template
used by your HATS application:
<HTML>
<HEAD>
<SCRIPT Language="Javascript">
function goHist(a)
{
history.go(a);//Go forward one.
}
</SCRIPT>
</head>
<body onLoad="goHist(1);">
