    DB2/zOS: when VARY WLM,APPLENV=name,REFRESH

    Hi,

    in V7 Admin. Guide ich read:

    <snip>
    4.2.10.4.2 Refreshing the environment for stored procedures or
    user-defined functions

    Depending on what has changed in a stored procedures environment, you
    might need to perform one or more of these tasks:

     Refresh Language Environment®.

    Do this when someone has modified a load module for a stored
    procedure, and that load module is cached in a stored procedures
    address space. When you refresh Language Environment, the cached load
    module is purged. On the next invocation of the stored procedure, the
    new load module is loaded.

    VARY WLM,APPLENV=nam e,REFRESH
    </snip>

    I can not find an explanationen "Depending on what has changed".
    Depending on what?

    Do I have to refresh only if the function is declared as RESIDENT AND
    linked as RENT/REUS or always ?

    So long,
    Rudi
