Since I’m dealing with Enterprise Portal quite a lot of time, I’ve made some private notes to have a look at, when someone asks me about the different versions of the EP. So, why not sharing this infos with you?
With this weblog I want to give you a quick overview to the SAP Enterprise Portal Landscape from the administrative point of view, how the EP changed during the different Support Packages and how the different components fit together.

Technology

EP60SP2 is the current, official released version of SAP Enterprise Portal and runs on Web Application Server 6.20. Starting with EP60SP3 the Enterprise Portal is part of the SAP Netweaver (still in Ramp-Up but it should be released this year, too) and it runs on WAS6.40.
So there was a big step between EP60SP2 and EP60SP3, because SAP switched the underlying Web Application Server.

Main differences between WAS6.20 and WAS6.40

This is a short list of the main topics I recognized during changing to the new version.
WAS6.40 (technically it’s based on J2EE-Version 6.30)

  • supports current JDKs (e.g. SUN JDK1.4.2_05)
  • integrated System Landscape Directory (SLD), can be used for connection purposes
  • (new) User Management Engine 4.0
  • has got its own database for configuration, SLD and UME
  • integrated WebDynpro runtime environment (SAPs solution of a MVC-Framework)
  • uniformed logging service (since 640SP4), putting all the logs together in one default trace file
  • Licensing the Portal moved to the WAS’s Keystore

Upgrade Strategies

Stacks / Support Packages / Patches / Hotfixes:

A stack consists of support package versions for all netweaver components. SAP guarantees that all components in a Netweaver Stack release work together. So it’s recommendable to upgrade all components always to the next stack.
A Support Package is a set of changes that upgrade a component to a higher SP-Level.
Patches are interim-changes on specific SP-Levels.
There used to be Hotfixes for patches for fixing problems in a short time, too. But I haven’t seen them in newer Netweaver-releases anymore.

There are some differeneces in how the support packages and patches are deployed. Support Packages since EP60SP3 are deployed via a SAPINST-Routine. Patches for EP60SP6 are deployed via SAPINST, too! Patches for KMCSP6 are deployed via SDM.

Current versions of the Enterprise Portal:

Enterprise Portal 5.0:
J2EE-Engine Patch25
EP50 SP6(Patch1.4)
CM50 SP6(Patch1.13)
PDK 50.0.6.0
Enterprise Portal 6.0 SP2:
WAS6.20 (J2EE-Engine) Patch25
EP60 SP2(Patch4.7)
KMC50 SP2(Patch4.5)
PDK 60.2.2
Enterprise Portal 6.0 >=SP3:
Netweaver Stack: 02(Preview) 03 04
WAS6.40 (J2EE-Engine) SP3->SP5 SP6 SP7
EP60 SP3->SP4 SP4(Patch4) SP6(Patch4)
KMC60 SP4 SP5(Patch1) SP6(Patch2)
PDK 60.3 60.3 60.6
Developer Studio SP5 SP6 SP7

EP50 runs on a J2EE-Engine Single node, with EP60, it’s a J2EE-Engine for Cluster, since then we’re also calling it Web Aplication Server (J2EE-Engine).

(Portal)Development

Portal Development Kits

The PDK consist mainly of javadocs, tutorials, tools for deploying/removing/browsing/running portal archives.
PDK50.x, imported as Business Package
PDK60.2.2 for EP60SP2 (.epa), imported as Enterprise pOrtal Archive in Portal
PDK60.3 for EP60SP3/4 (.sca), deployed via SDM
PDK60.6 for EP60SP6 (.sca), deployed via SDM

PlugIn for Eclipse-based IDEs:

It consists of Wizards for creating Portal Archives (.PAR files) and deploying them online on the Portal Serer. When using Netweaver Developer Studio, the PlugIn is full integrated and obsolete.

Netweaver Developer Studio:

Eclipse based IDE for developing WebDynpro Application as well as Portal Archives (.PAR files) and deploying them out of the IDE on the server.

    Isn’t SP an abbreviation for Solution Package or have SAP gone back on this ?
    There also is a bit of confussion regarding which patch levels on the SAP J2EE go well together with which portal version. In the installation procedure for SP2 patch 4 for example, it says that you should not install any newer PL than PL 22 since this is what patch 4 has been tested for. Generally I’ve been following the rule that if you do not have a problem that is specificaly fixed in the next patch/hotfix/PL, do not upgrade.
    It will be interesting to see how the netweaver stack manages to do synchronized releases of all the components in the stack.

        as far as I can see that note only talks about which java JVM’s go together with the SAP J2EE (the tittle is ” JDK support for J2EE 6.20 in vm_support.properties”).

    I was unable to locate the PDK for EP 5.0.
    Is it still alive somewhere?

    I needed it to debug some JSP pages for ISA, instead of running them on the WebAS.

    Does anyone have a mirror somewhere?

    If not, is there a How To to configure Tomcat 4.1 or later in order for it to display the taglibs?

    Any help will be very welcome!
    Pls, reply to my personal e-mail:

    Thanks in advance!
