<h1>Description</h1>
|
|
<p>Connects to the DB server on the indicated hostname and sets up a channel
|
|
for communication.
|
|
<p>The <b>cl_timeout</b> argument specifies the number of seconds the client
|
|
should wait for results to come back from the server. Once the timeout
|
|
has expired on any communication with the server, Db.DB_NOSERVER will
|
|
be returned. If this value is zero, a default timeout is used.
|
|
<p>The <b>sv_timeout</b> argument specifies the number of seconds the server
|
|
should allow a client connection to remain idle before assuming that
|
|
client is gone. Once that timeout has been reached, the server releases
|
|
all resources associated with that client connection. Subsequent attempts
|
|
by that client to communicate with the server result in
|
|
Db.DB_NOSERVER_ID indicating that an invalid identifier has been
|
|
given to the server. This value can be considered a hint to the server.
|
|
The server may alter this value based on its own policies or allowed
|
|
values. If this value is zero, a default timeout is used.
|
|
<p>The <b>flags</b> parameter is currently unused, and must be set to 0.
|
|
<p>When the DbEnv.set_server method has been called, any subsequent calls
|
|
to Berkeley DB library interfaces may return either <a name="DB_NOSERVER">DB_NOSERVER</a> or
|
|
<a name="DB_NOSERVER_ID">DB_NOSERVER_ID</a>.
|
|
<p>The DbEnv.set_server method throws an exception that encapsulates a non-zero error value on
|
|
failure.
