Rational Developer

IBM Rational Software Delivery Platform for System i

Version history

RDi's predecessor product was WDSC. WDSC's latest version was 7.0, and it was tied to the Websphere Application Server's release numbering rather than the System i's i5/OS numbering. This confused some people because WDSC included both host and client software. The host software was obviously tied to i5/OS, but the client software could operate with different versions of i5/OS.

With this release, IBM Rational have broken the version numbers apart, so now the host tools and compilers have version numbers that match the version of i5/OS they are intended to operate with. The client tools remain tied to Websphere's versioning system.

RDi version	i5/OS V5R2	i5/OS V5R3	i5/OS V5R4	IBM i v6.1	IBM i v7.1	Client OS
V7.1	No	Yes	Yes	Yes	?	Windows
V7.5	No	Yes	Yes	Yes	?	Windows
V7.6	No	No	Yes	Yes	Yes	Windows
V8.0	No	No	Yes	Yes	Yes	Windows & Linux

Fix packs

Fix packs are IBM-released fixes and patches that repair defects and sometimes add enhancements between full releases. RDi has had fix packs prior to those listed here but they were recorded in the WDSC_Fixpacks article. IBM announces fix packs at the RPG Café and also at the WDSCI-L list on Midrange.com.

To install a fix pack, end RDi, back up your workspace, start IBM Installation Manager and choose Update. Some fix packs can take significant time to complete - users have reported half an hour or more. Try updating over lunch when you won't be tempted to cancel it for taking so long...

Packaging

IBM Rational announced this version of its System i development tools January 29, 2008. Planned release date is March 21, 2008. The PID code for the host tooling is 5761-WDS but there are many separate feature codes -- check the Host tools announcement for details. The PID codes for the client tooling are 5724-T82 and 5733-RDI. Again, check the Client Announcement for details on the many feature codes that will affect your ordering.

Pricing and ordering

The pricing structure for WebSphere Development Studio for System i (5761-WDS) is based on the processor group (also known as software machine group or software tier) of the machine on which the program is used and on the number of named users of the program. Each license entitlement contains the processor group and the user quantity. Additional users entitlements may be purchased as needed.

A user of WebSphere Development Studio for System i (5761-WDS) is defined as a named user who is capable of executing the program.

The customer has the option to order any or all of the three WebSphere Development Studio for System i features separately. Each feature is priced differently.

For upgrades from ADTS (SEU and PDM), there will be entitlements for those on software maintenance ([SWMA]), meaning that a given software tier will come with a certain number of user licenses (called a Proof of Entitlement.) Note that downgrading (e.g. from a P10 to a P05), no credits are given.

For new purchases (not upgrades), each tier will also be required to purchase a minimum number of licenses.

As of 7 February 2008, George Farr (IBM) says there will be no entitlement upgrades from WDSC to RDi. You can upgrade your green screen tooling through entitlement but you'll have to purchase the GUI tooling. iSociety chat 06 Feb 2008.

Software tier	SWMA entitlement	New purchase minimum
P05	4 seats	1 seats
P10	8 seats	3 seats
P20	12 seats	4 seats
P30	16 seats	10 seats
P40	20 seats	15 seats
P50	30 seats	20 seats
P60	40 seats	25 seats

Pricing involves a charge for the processor tier, and a charge for each user. Call IBM or your Business Partner for specific pricing.

Extensions

RDi, like WDSC can be modified by programmers. The Eclipse platform provides a mechanism called extensions. Writing an extension requires knowledge of Java as well as the internal structure of RSE and Lpex. New to RDi is a refactored RSE called variously OpenRSE, Target Management (TM) / RSE and DSDP-TM RSE. Refactored means that if you have written extensions for WDSC or RDi 7.1, they will need to be redone for RDi 7.5. A cautionary note is in order about TM/RSE 2.0 as well: IBM considers this to be a provisional release - any and all interfaces can be changed, breaking backward compatibility. IBM intends that TM/RSE 3.0 will be stable and hardened.

Installation Issues

Windows 7

Due to changes in the Windows OS, Rational Developer applications cannot be installed in "Virtualized" directories unless you run the application with administrative privileges. The default application directory in Windows, "Program Files" (and "Program files (x86)"), are virtualized.

If you install the Rational Developer applications in those virtualized directories you will have to launch the application by right-clicking on the shortcut and select "Run as administrator".

Alternatively, you can install the application in another directory on the system that is not virtualized. Any directory you create off the root will not be virtualized.

WDSC 7.0 & RDi 7.1

It is possible to install WDSC 7.0 & RDi 7.1 in Windows 7, although it's been reported that you need the current version of the Installation Manager application. The Installation Manager can be downloaded from http://www-947.ibm.com/support/entry/portal/Downloads/Software/Rational/IBM_Installation_Manager. For more details, see WDSC installation

Linux

• Depending on how you copied the installer to your linux system, you might have to adjust permissions on some of the files.
  • Add execute permissions to InstallerImage_linux/jre_5.0.3.sr8a_20080811b/jre/bin/java
  • Add execute permissions to InstallerImage_linux/install
• On Ubuntu 64 bit, if you have 64 bit Java and JVM ends with exit code 13 when installing, you can try this: edit file install.ini and change the line that reads "jre_5.0.3.sr8a_20080811b/jre/bin/java" to "./jre_5.0.3.sr8a_20080811b/jre/bin/java".
