Sometimes, SDM (Software Deployment Manager) will not start if you recently updated the SDM. To solve this issue, please proceed as follow:
Starting SDM will not work if you do not first edit some files:
Edit the SDM file
<DRIVE>:\usr\sap\<SID>\DVEBMGS<NO>\SDM\program\sdm_jdk.bat (Add-in Installation)
<DRIVE>:\usr\sap\<SID>\JC<NO>\SDM\program\sdm_jdk.bat (Standalone Engine)
set sdm_java_home=/QIBM/ProdData/Java400/jdk14
to
set sdm_java_home=%JAVA_HOME%
and;
set sdm_heap_size=512
Then you can start SDM from a Windows Client:
<DRIVE>:\usr\sap\<SID>\DVEBMGS<NO>\SDM\program\RemoteGui.bat (Add-in Installation)
<DRIVE>:\usr\sap\<SID>\JC<NO>\SDM\program\RemoteGui.bat (Standalone Engine)
Note
Above changes also can help to solve JSPM Start Problems.
