SDM stands for Software Deployment Manager.
SDM tool is responsible for deploying software in AS Java of SAP.
SDM is used by a large number of tools like JSPM, NWDI etc in the AS Java environment for deploying software. Also, SDM is the tool used to deploy special software packages that are received from SAP and other providers.
Software Deployment is the last step in the delivery process of software. That is the transfer of supplied software packages (SDAs, SCAs or other j2ee archives) into the runtime environment of the SAP system.
How to start or stop SDM independent of the java engine?
Usually SDM starts/stops with Java engine. However, it is also possible to start or stop SDM independent of the java engine. Please find below process to do the same.
i) Open command prompt and navigate to the usr/sap/<SID>/<Instance_name>/SDM/program directory of your J2EE engine
ii) Execute stopserver.bat file in windows to stop SDM. Incase if Os is UNIX related, execute stopserver.sh file. This stops SDM. To verify, whether SDM is stopped or not, it can be checked in MMC or SAP Management Console or JCMon or JSMon
iii) Execute startserver.bat file in windows to start SDM. Incase if Os is UNIX related, execute startserver.sh file. This starts SDM. To verify, whether SDM is started or not, it can be checked in MMC or SAP Management Console or JCMon or JSMon
Modes of SDM:
There are 2 modes in SDM. They are
♥ Standalone
♥ Integrated
These modes determine whether SDM will have link to Java control framework or not.
In standalone mode, SDM will not have link to Java control framework. Please note that in standalone mode, SDM will no longer start or stop automatically with J2EE engine.
In Integrated mode, SDM does have a link to the Java control framework.
Changing SDM Modes:
i) Open command prompt and navigate to the usr/sap/<SID>/<Instance_name>/SDM/program directory of your J2EE engine.
ii) Execute stopserver.bat file in windows to stop SDM. Incase if Os is Unix related, execute stopserver.sh file
iii) To remove the link between SDM and the java control framework, execute the following command in the command line in respective operating systems.
sdm jstartup “mode=standalone” à (In windows Os)
sdm.sh jstartup mode=standalone à ( In Unix os)
iv) To integrate the SDM in the java control framework, execute the following command in the command line in respective operating systems.
sdm jstartup “mode=integrated” à (In windows os)
sdm.sh jstartup mode=integrated à (In Unix os)
v) Execute startsterver.bat file in windows to start SDM. Incase, if Os is Unix related, execute startserver.sh file
