Managing SNAplus2 Clients

Managing Win16 Clients

attempts to contact the server speciﬁed in Server2 using a directed message. If this fails, it tries the server speciﬁed in Server3, and so on.

These server names are optional, but provide a backup mechanism if the broadcast method of locating a server fails or if the server speciﬁed by Server1 is unavailable.

If the client tries all the servers listed without success, it waits for the number of seconds speciﬁed by the server_lost_timeout parameter, then restarts the process of trying to contact a server (either with UDP broadcasts or with the ﬁrst server listed).

The parameters Server2–Server10cannot be set to * to indicate the use of UDP broadcasts. Only the Server1 parameter can be used to indicate this, because the * value must precede any server names in the ﬁle.

[Logging]

The [Logging] section of the ﬁle speciﬁes logging options for the client. These options can be used to specify client logging settings that override the logging options speciﬁed for the domain as a whole. For more information about specifying domain logging options, see “Conﬁguring Logging”.

If central logging is enabled, all log messages are written to a central ﬁle on a server. In this case, only the exception_logging_enabled and audit_logging_enabled parameters speciﬁed here are used; the remaining parameters are ignored.

The logging options are speciﬁed as follows:

exception_logging_enabled

Set this parameter to one of the following values:

YES

Record exception messages.

NO

Do not record exception messages.
