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● Outdated appearance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

Default Rendering: Global Rules

● Global Rules specify:

the project-wide replacement

of a certain type of host input field

with a particular widget



WebSphere


Default Rendering: Global Rules Example

Search for all host input fields preceded by “===>”…

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

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

appleorangebanana

fruitList appleorangebanana



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 global variable table

Client C's global variable table

Global Variable Tables

The table is destroyed along with the rest of the client data when the session ends.

● Verify users:

Through a single authentication challenge

Across multiple applications


Host System

HostApp 1

HostApp 2

HostApp 3

HATSUser ID

Password

Network Security


WebSphere


Single Signon support in HATS

● Web Express Logon (WEL)

Works with IBM Tivoli Access Manager

Or, use a certificate-based authentication

Or, create your own plug-in for your environment



WebSphere


Web Express Logon

● Macro-based automation relies on

HATS macro (usually the connect macro)

Credential Mapper Plug-ins (CMP)

Credential Mapper (CM)

Network Security Plugin

● WebSphere Portal is also supported



WebSphere


Single Signon support in HATS continued

● 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.

HATS V6 Solution 6: Web Services


WebSphere


Solution 6: Web Services

● Self-contained applications based on open standards

● Can be invoked over the Web

● Transforms a process, not host screens


WebSphere


Sample Web Services usage

● The user of a wireless device can access an online transaction system to:

Check status on inventories

Place orders

Ship products to end users

Check deliveries

● All of these functions are published as Web services on the server

● The wireless device uses a Web services consumer client to interact with the server



WebSphere


Web Services continued

● Use HATS and Rational tools to build Web Services

Formulate information using SOAP, WSDL, and UDDI

Create Web Services clients

● Create Web Services from:

Integration Objects

EJB Access Beans



WebSphere


Integration Objects (IO) (*.java)

● Java beans that encapsulate interactions with host applications

● Created from previously recorded macros

● Invoke from HATS Business Logic or other WebSphere apps

● Use Integration Objects if:

Your application connects to more than one host app

You want to encapsulate your host interactions into Enterprise JavaBeans (EJBs) or Web services

You want to build Web pages based on the inputs and outputs of a macro



WebSphere


Integration Objects: Building Web Pages (*.jsp)

● Model 1 Web Pages

The "traditional" HATS approach to building a JSP

For simple applications

● Struts Web Pages

Create complex Web applications

These applications are more easily maintained

● JavaServer Faces (JSF) Pages

For developing user interfaces (UI) for Web applications

Use Page Designer and the Palette to edit

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

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.

HATS HTML Compression Support

● Transformation content is dynamic and approximately 20% of the page content

● 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);">
