WebSphere How To: fix errore ADMG0011E while Application Server deletion

Working on a WebSphere 8.5.0.2 environment I was unable to delete an Application server getting the error ADMG0011E:

An error occurred while deleting the server. ADMG0011E: An unexpected exception occurred com.ibm.websphere.management.exception. AdminException: Exception in removeTargetFromCUs()..

Inside DMGR and NodeAgent logs I wasn't able to find anything related but inside DMGR FFDC, folder I got a log generated during the deletion time frame with following exceptions:

Caused by: com.ibm.wsspi.management.bla.op.OpExecutionException: CWWMH0121E: Could not read configuration data for composition unit "WebSphere:cuname=<Application_Name>,cuedition=BASE". Error data: com.ibm.wsspi.management.bla.op.OpExecutionException: Enterprise application data for composition unit "WebSphere:cuname=<Application_Name>,cuedition=BASE" could not be read. at com.ibm.ws.management.bla.model.CompositionUnitConfig.read(CompositionUnitConfig.java:293)

After some research  I've found this question on  DeveloperWorks and than I've fixed the issue following this steps:

1. Deployement Manger stop
2. check inside WAS_INSTALL_ROOT/profiles/Dmgr_ProfileName/config/cells/Cell_Name/applications if an  Application_Name.ear folder with same FFDC name Application_Name was present
3. If the folder on step 2 was missing check inside WAS_INSTALL_ROOT/profiles/Dmgr_ProfileName/config/cells/Cell_Name/blas and than delete  Application_Name if present
4. check inside WAS_INSTALL_ROOT/profiles/Dmgr_ProfileName/config/cells/Cell_Name/cus if the  Application_Name folder is present than delete
5. Deployement Manger start
6. Full Nodes Sync from WebSphere console
7. Tried again to delete the  Application server and it worked!

Sametime Console and was version not supported on Windows

Installing a Sametime SSC on Windows 2008R2 i was stopping with a "WAS version not supported".

The issue was i've installed WAS 8.5.5 only with EN language on a IT server and IBM installation Manager was set in Italian.

To fix it , we could modify the followin file
<Installation Manager folder>\eclipse\configuration\config.ini

and add   osgi.nl=    with new language code

In my case i've insert    osgi.nl=en   and after restart with IBM IM has started in English and I was been able to complete the setup.

Here  the IBM technote about IM language change.

IBM Sametime 8.5.2 IFR1 has started support for Was 7.0.0.23

IBM Sametime  from 8.5 release has changed Application server for many of his functionality leaving Domino to Websphere Application Server 7.
WAS, as other IBM sw has many maintenace FixPack and fix to solve problem and get better performance and stability.

In this IBM Technote you could find a table with the correct release of WAS who are certified for Sametime. Yesterday in last update WAS 7 Fixpack 23 becoming supported for Sametime 8.5.2 IFR1
