Abstract
A system, such as a database system, includes a shared library having plural routines. A linking procedure is used in which a routine (referred to as a “first routine”) is linked to a stub library containing stub programs corresponding to other routines that the first routine is authorized to invoke. If no linking error occurs, the first routine is then linked to the shared library. In some implementations, the first routine is one of a user-defined method (UDM), user-defined function (UDF), or stored procedure created in response to a database query language (e.g., Structured Query Language or SQL) statement.
