Define Documentation

#define USE_PTHREAD_MUTEX   1

Determines that we use pthread-based mutex for queue_based_lock_t.

The Shore-MT release contained alternatives for scalable locks in certain places in the storage manager; it was released with these locks replaced by pthreads-based mutexes.

The alternatives were described in [JPHAF1], but have not been tested for the Shore 6.0 release. The code for these alternatives is distributed for further experimentation, but it is not not compiled in.

If you wish to experiment with the mcs locks, you'll have to undefine this macro.
