Answers General Questions
What is the difference between update and upgrade, if any?
Updating SAP products is for applying support packs, patches or hotfixes. Upgrade term is used exclusively when product release is changed.
Answers Release Upgrades
Can I upgrade my Netweaver Java system to a new release and apply the latest Support package at once?
Yes. Java upgrade offers the feature to bind the latest SP stack to the archives present on the Java DVD.
Can I upgrade my Netweaver Java system to a new release and upgrade my third party software simultaneously?
Yes. Just make sure that the software SDAs from the source(old) Netweaver release have preserved their names and that the new SDAs are packed in an SCA. Put the SCAs in the inbox directory before starting PREPARE.
Answers Support Package Implementation
Can I apply Netweaver support package stack and patches in one step?
Yes. From JSPM SP14 there is a functionality to apply selected patches with stack option in one step. Please see note #1080821.
What is the benefit of using Netweaver support package stack over update of single packages?
Consistency. The XML file for selected OS/DB (if you follow the option Download basket/Save As File) contains a description of the Support Package Stack. This XML file allows JSPM to deploy a consistent Support
Package Stack to your Netweaver system without any additional input. Please see note #884537.
What is the recommended free space on file system JSPM needs to operate smoothly?
When patching Netweaver native components like Kernel or IGS - two to three times the size of SAR archives.When patching Netweaver 7.0 SDM - approximatelly the size of SDMKIT.jarWhen patching Java components - two or three times the cumulative size of all Java archives (downloaded SCAs), depending on the Netweaver release.Additionally, JSPM requires about 50MB under the JSPM directory for its logs and data files. Please see note #891895 for details.
Is it possible to remove/undeploy software components with JSPM?
No. Undeployment of Netweaver components or applications can easily break runtime dependencies. In Netweaver Java 7.0 one can use SDM for undeployment.
How to redeploy same component with JSPM?
JSPM does not allow to deploy an SCA with the same version (release, SP-level, patch-level) as an already deployed component. However, in some special cases you may need to redeploy an SCA with the same version. Use command line:go "-config=/jspm/forceMode=true" "-config=/jspm/deployVersionRule=updateAll" to redeploy all SDAs. See note #1123333 for more options.
How to use JSPM on UNIX system?
When JSPM is started it automatically starts its GUI on the local machine. If SAP system to be updated is on UNIX, it is recommended to redirect JSPM
GUI to a Windows machine using Hummingbird Exceed software. Check note #1013976 for details.
How to shorten update procedure of dual stack NW 7.0 systems?
Applying an SP to dual stack NW 7.0 systems sometimes takes hours due to large amount of services and applications running on top of Netweaver. The update of ABAP and Java stacks can be done in parallel, as far as few prerequisites are met. Please check "Updating Netweaver ABAP and Java stacks in parallel" blog to minimize the technical downtime during maintenance (advanced users).
How do we get software component archives from SMP in an automated way?
Starting from Netweaver 7.0 SP14, one can use Solution Manager Maintenance Optimizer for automated downloads. Software Lifecycle Manager (SLM) and Software Logistics Controller (SLC) take care for this automated service.
Purpose
The purpose of this document is to list all the undeployment options available to undeploy .SDA (Software deployment Archive) and similar files on SAP J2EE
servers Netweaver release: 7.1/7.2/7.3 and the upcoming 7.4 version. For a similar knowledge base article for the deployment of these components, check SAP KBA
document :http://service.sap.com/sap/support/notes/1715441.In earlier SAP releases (version 6.40 and 7.00) the Software Deployment manager (SDM) tool could have been easily used for this. However, it has depreciated in the
latter releases.
Option 1
The best option to use is the J2EE TELNET "UNDEPLOY" command.
1) Open telnet connection and run the below commands:
> lsc (to list the available server nodes)> jump <server node> (usually jump 0)
> add deploy> undeploy -h (to get the command syntax. For more information,
checkhttp://wiki.sdn.sap.com/wiki/display/TechTSG/(JSTSG)(Telnet)DeployController+Commands
Option 2
The Netweaver Developer Studio undeploy view can also be used to this purpose. Firstly navigate to NWDS -> window -> preferences and maintain the j2ee server
details:
Now open the undeploy view by clicking on Window -> show view -> other
and select the undeploy view:
Once this is done, you can select the DC components that are part of the SCAs that
need to be undeployed. It is also possible to select the whole SCA file using this technique:

Option 3
The guiconsole.bat in the location /usr/sap/<SID>/J<nr>/j2ee/console is a script that will inturn open the telnet application and you can commence undeployment
as mentioned in option 1.Phases of a SAP Project (ASAP)
Phase I: Project Preparation
Decision makers define clearly Project objectives and an effective decision making process.
Define Project organization and Roles. Implementation scope is finalized System Landscape and technical requirements are finalized Infrastructure (Hardware/Interfaces) High level Strategies for client Archiving strategy Issues of Data bases Other issues like Unanticipated tasks Normal tasks that can not be completed External factors that need to be dealt with
Phase II: Blue Print Phase
Scope of R/3 implementation is defined. Business blue print is created.o Tools used for this is ASAP Implementation assistant Question and Answer Data Base (Q&A dB) Business Process Master List (BPML) R/3 Structure Modules Business Navigator and External Modeling tools? Project Management (Activities like…) Conducting Status Meeting for Project Meeting Conducting Steering committee meetings Addresses the issues like Organizational Change Management Other Activities Like Project Team Training Developing the system environmento Defining Org Structure Define Business Process
Phase III: Realization Phase
Configuring the R/3 System Defining the Authorizations in R/3 Defining the work flow Creating Use Documentation System manager procedures Developing the System Test plans Define the Service level Commitment Establishing the System Administration function Setting up the Quality Assurance environment
Phase IV: Testing and Final Preparation
Testing, user Training, System management and Cutover activities Test Plan has the activities of: Testing the conversion procedures and programs Total Interface programso Volume and Stress testing Final User acceptance testingo Developing a Final Go-Live strategy Redirection to Go-Live? Preparation of End-user documentation Training for the End Users Technical environment installation on Production system and testing Transfer of Legacy data and preparation plan for Go-Live
