<p>
Sets timeout values, in microseconds, for locks or
transactions in the database environment, the wait time for
a process to exit the environment when DB_REGISTER recovery
is needed, and how frequently to check for failed processes
during mutex waits.
</p>
<p>
The syntax for setting timeout value for database
environment's lock, before recovery is started, and
transaction is as follows:
</p>
<div class="itemizedlist">
<ul type="disc">
<li>
<p>
DB_SET_LOCK_TIMEOUT
</p>
<p>
Configures the database environment's lock timeout value.
The syntax of the entry in the <a href="../../programmer_reference/env_db_config.html#env_db_config.DB_CONFIG" class="olink">DB_CONFIG</a> file is a single
line with the string <code class="literal">set_lock_timeout</code>,
one or more whitespace characters, and the lock timeout
value.
</p>
</li>
<li>
<p>
DB_SET_MUTEX_FAILCHK_TIMEOUT
</p>
<p>
If failchk broadcasting has been configured, then
this sets the timeout value on how long a thread will
wait for a mutex lock before checking whether
<a class="xref" href="envfailchk.html" title="DbEnv::failchk()">DbEnv::failchk()</a> has marked the mutex as failed. The
default is to check once every second. The syntax
of the entry in the <a href="../../programmer_reference/env_db_config.html#env_db_config.DB_CONFIG" class="olink">DB_CONFIG</a> file is a single
line with the string
<code class="literal">set_mutex_failchk_timeout</code>,
one or more whitespace characters, and the wait
timeout value.
</p>
<p>
If failchk broadcasting has not been configured,
then setting this timeout value results in an
error.
</p>
</li>
<li>
<p>
DB_SET_REG_TIMEOUT
</p>
<p>
Sets the timeout value on how long to wait for processes to
exit the environment before recovery is started. The
syntax of the entry in the <a href="../../programmer_reference/env_db_config.html#env_db_config.DB_CONFIG" class="olink">DB_CONFIG</a> file is a single
line with the string <code class="literal">set_reg_timeout</code>,
one or more whitespace characters, and the wait timeout
value.
</p>
</li>
<li>
<p>
DB_SET_TXN_TIMEOUT
</p>
<p>
Sets the timeout value for transactions in this database
environment. The syntax of the entry in the <a href="../../programmer_reference/env_db_config.html#env_db_config.DB_CONFIG" class="olink">DB_CONFIG</a>
file is a single line with the string
<code class="literal">set_txn_timeout</code>, one or more whitespace
characters, and the transaction timeout value.
</p>
</li>
</ul>
