JSPM: All selected SDAs and SCAs have already been deployed before...

I am not exactly sure what caused this error, but while trying to apply Java support packages, I came up with the following error in JSPM:

All selected SDAs and SCAs have already been deployed before

This is a problem, because the Java system still shows to be on an older support package level, but a piece of functionality I need to use is dependent on a higher SP level.

The problem is that the SDM is no longer in sync with the Java stack. The solution is to re-synchronize them.

Here is the procedure:

1. Go to the /usr/sap///SDM/program

2. Run StopServer.bat

3. In the command line, execute the following commands:
- On a Microsoft Windows system:
-- sdm jstartup “mode=standalone”
-- sdm systemcomponentstate “mode=activate”
-- sdm jstartup “mode=integrated”

- On a UNIX system:
-- ./sdm.sh jstartup “mode=standalone”
-- ./sdm.sh systemcomponentstate “mode=activate”
-- ./sdm.sh jstartup “mode=integrated”

- On an IBM eServer iSeries system:
-- QSHcd /usr/sap///SDM/program
-- ./sdm.sh jstartup “mode=standalone”
-- ./sdm.sh systemcomponentstate “mode=activate”
-- ./sdm.sh jstartup “mode=integrated”

4. Run StartServer.bat

5. Restart JSPM

Your SDM should now be in sync with the database.

Hope this helps...
