MSSQL 2008 - Database size getting smaller after EHP upgrade??

Hi All,

Did anyone observe the DB size of MSSQL 2008 after EHP upgrade?

In my two system, after upgraded to EHP5 and EHP2 respectively, the database is getting smaller compare to before upgrade, estimated 5-10gb.

EHP upgrade is unlike DBEXPORT, it shouldn't have any reorganization features and so do MSSQL.

Any idea?

Cheers,

Nicholas Chang

    Did you run SGEN already?

    Hi Markus,

    Appreciate if you can give some insight::

    Sgen was run on source system and object had pre-compiled. When source system upgrade to EHP2 or 5, massive new objects are written to the database along with the existing compiled objects. As a result, DB size of upgraded system before SGEN shouldn't smaller than source DB?

    Thanks,
