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.
The syntax for setting timeout value for database environment's lock, before recovery is started, and transaction is as follows:
DB_SET_LOCK_TIMEOUT
                        Configures the database environment's lock timeout value.
                        The syntax of the entry in the DB_CONFIG file is a single
                        line with the string set_lock_timeout,
                        one or more whitespace characters, and the lock timeout
                        value.         
                    
DB_SET_MUTEX_FAILCHK_TIMEOUT
                        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
                        DB_ENV->failchk() has marked the mutex as failed. The
                        default is to check once every second. The syntax
                        of the entry in the DB_CONFIG file is a single
                        line with the string
                        set_mutex_failchk_timeout,
                        one or more whitespace characters, and the wait
                        timeout value.
                    
If failchk broadcasting has not been configured, then setting this timeout value results in an error.
DB_SET_REG_TIMEOUT
                        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 DB_CONFIG file is a single
                        line with the string set_reg_timeout,
                        one or more whitespace characters, and the wait timeout
                        value.         
                    
DB_SET_TXN_TIMEOUT
                        Sets the timeout value for transactions in this database
                        environment. The syntax of the entry in the DB_CONFIG
                        file is a single line with the string
                        set_txn_timeout, one or more whitespace
                        characters, and the transaction timeout value.
