<h1>Description</h1>
|
|
<p>This manual page describes the specific details of the DbEnv
|
|
class, which is the center of the Berkeley DB environment.
|
|
<p>The following <b>flags</b> value may be specified:
|
|
<p><dl compact>
|
|
<p><dt><a name="DB_CLIENT">DB_CLIENT</a><dd>Create a client environment to connect to a server.
|
|
<p>The DB_CLIENT flag indicates to the system that this environment
|
|
is remote on a server. The use of this flag causes the environment
|
|
methods to use functions that call a server instead of local functions.
|
|
Prior to making any environment or database method calls, the
|
|
application must call the <a href="../api_cxx/env_set_server.html">DbEnv::set_server</a> function to establish
|
|
the connection to the server.
|
|
<p><dt><a name="DB_CXX_NO_EXCEPTIONS">DB_CXX_NO_EXCEPTIONS</a><dd>The Berkeley DB C++ API supports two different error behaviors. By default,
|
|
whenever an error occurs an exception is thrown that encapsulates the
|
|
error information. This generally allows for cleaner logic for
|
|
transaction processing, as a try block can surround a single
|
|
transaction. However, if DB_CXX_NO_EXCEPTIONS is specified,
|
|
exceptions are not thrown, instead each individual function returns an
|
|
error code.
