Establishes a connection to a SESAM database handler task. The connection is always "persistent" in the sense that only the very first invocation will actually load the driver from the configured SESAM OML PLAM library. Subsequent calls will reuse the driver and will immediately use the given catalog, schema, and user.
When creating a database, the
"catalog" name is
specified in the SESAM configuration directive
//ADD-SQL-DATABASE-CATALOG-LIST ENTRY-1 =
*CATALOG(CATALOG-NAME = catalogname,...)
schema references the desired database
schema (see SESAM handbook).
"user" argument references one of the users
which are allowed to access this
"schema" combination. Note that
"user" is completely independent from both the
system's user id's and from HTTP user/password protection. It appears
in the SESAM configuration only.
