<b>Description: DbDeadlockException</b>
|
|
<p>This information describes the DbDeadlockException class and how
|
|
it is used in the Berkeley DB library.</p>
|
|
<p>A DbDeadlockException is thrown when multiple threads competing
|
|
for a lock are deadlocked, when a lock request has timed out, or when a
|
|
lock request would need to block and the transaction has been configured
|
|
to not wait for locks. One of the threads' transactions is selected for
|
|
termination, and a DbDeadlockException is thrown to that thread.</p>
|
|
<p>The <a href="../api_cxx/except_class.html">DbException</a> errno value is set to DB_LOCK_DEADLOCK.</p>
