This section provides information about how to
alter a C UDR and how to unload a shared-object file.
Alter a routine
The SQL statements ALTER FUNCTION, ALTER PROCEDURE,
and ALTER ROUTINE allow you to alter some of the routine modifiers
of a UDR after the UDR has been registered.
Unload a shared-object file
In an attempt to keep memory usage to a minimum, the routine
manager attempts to unload a shared-object file when it finds that
no one is using any of its UDRs. That is, it unloads a shared-object
file when all references to the UDRs within the shared-object file
are removed from the internal cache of the database server and any
one of them is marked as being dropped.
