ex_access.c Using just the DB access methods.
ex_apprec Application-specific recovery.
ex_btrec.c Using the BTREE access method with record numbers.
ex_env.c Setting up the DB environment.
ex_lock.c Locking.
ex_mpool.c Shared memory buffer pools.
ex_repquote Replication. This creates a toy stock quote server
with DB's single-master, multiple-client replication,
with communication over TCP.
ex_tpcb.c TPC/B.
Ex_tpcb sets up a framework in which to run a TPC/B test.
Database initialization (the -i flag) and running the
benchmark (-n flag) must take place separately (i.e.,
first create the database, then run 1 or more copies of
the benchmark). Furthermore, when running more than one
TPCB process, it is necessary to run the deadlock detector
(db_deadlock), since it is possible for concurrent tpcb
processes to deadlock. For performance measurement, it
will also be beneficial to run the db_checkpoint process
as well.
