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()">
|
||
|
||
<span>DbEnv::failchk()</span>
|
||
</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>
