<h1>Description</h1>
|
|
<p>Recover to the time specified by <b>timestamp</b> rather than to the most
|
|
current possible date.
|
|
The <b>timestamp</b> argument should be the number of seconds since 0
|
|
hours, 0 minutes, 0 seconds, January 1, 1970, Coordinated Universal Time,
|
|
i.e., the Epoch.
|
|
<p>Once a database environment has been upgraded to a new version of Berkeley DB
|
|
involving a log format change (see <a href="../ref/upgrade/process.html">Upgrading Berkeley DB installations</a>, it is no longer possible to recover
|
|
to a specific time before that upgrade.
|
|
<p>The DBENV->set_tx_timestamp interface may only be used to configure Berkeley DB before
|
|
the <a href="../api_c/env_open.html">DBENV->open</a> interface is called.
|
|
<p>The DBENV->set_tx_timestamp function returns a non-zero error value on failure and 0 on success.
|
|
<h1>Errors</h1>
|
|
<p><dl compact>
|
|
<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
|
|
<p>It is not possible to recover to the specified time using the
|
|
log files currently present in the environment.
