2 # Geniwrapper Configuration Info
4 # This module holds configuration parameters for geniwrapper. There are two
5 # main pieces of information that are used: the database connection and
6 # the PLCAPI connection
10 # Geniwrapper uses a MYSQL database to store records. This database may be
11 # co-located with the PLC database, or it may be a separate database. The
12 # following parameters define the connection to the database.
14 # Note that Geniwrapper does not access any of the PLC databases directly via
15 # a mysql connection; All PLC databases are accessed via PLCAPI.

89 # Geniwrapper uses a PLCAPI connection to perform operations on the registry,
90 # such as creating and deleting slices. This connection requires an account
91 # on the PLC server with full administrator access.
93 # The Url parameter controls whether the connection uses PLCAPI directly (i.e.
94 # Geniwrapper is located on the same machine as PLC), or uses a XMLRPC connection
95 # to the PLC machine. If you wish to use the API directly, then remove the Url
96 # field from the dictionary.
