48: LON Host ID is an internal ID within the LON-CAPA
49: network used to specify the uniqueness of a particular
50: LON-CAPA server. Current examples include "msul1", "msua3",
51: "103l1", "fsul1", and "107a1".
52: END
53: , "lonRole" => <<END
54: LON Role specifies the role this machine plays within
55: the LON-CAPA network. There are two valid values for
56: this:
57: * library
58: * access
59: END
60: , "lonAdmEMail" => <<END
61: LON System Administrator E-Mail specifies the e-mail
62: address of an institutional member responsible for
63: direct upkeep of this server.
64: END
65: , "lonDefDomain" => <<END
66: LON Domain is a unique internal identifier within the LON-CAPA network
67: specific to the home institution. Current examples include
68: "msu", "fsu", "103", and "107".
69: END
70: , "lonLoadLim" => <<END
71: LON Load Limit specifies a threshold of activity within The Learning
72: Online Network that this machine should provide. We strongly recommend
73: a value of 2.00. Depending on processor architecture (dual processor),
74: this value may be increased, but there is no readily available measure
75: in this regard.
76: END
77: , "lonExpire" => <<END
78: LON Expiration Time indicates, in seconds, how long distributed resources
79: should be held in the server's cache when not being accessed by students,
80: instructors, or any other class of user. We recommend a value of 86400.
