# $Id: README,v 11.5 2002/02/26 16:22:45 krinsky Exp $
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.

* bench_001 - time bulk fetch interface.
* Without -R builds a btree acording to the arguments.
* With -R runs and times bulk fetches. If -d is specified

* otherwise the DB_MULTIPLE_KEY interface is used.
*
* ARGUMENTS:
* -c cachesize [1000 * pagesize]
* -d number of duplicates [none]
* -E don't use environment
* -I Just initialize the environment
* -i number of read iterations [1000000]

* -n number of keys [1000000]
* -p pagesize [65536]
* -R perform read test.
* -T incorporate transactions.
