DDBMS is a testbed of an OLTP distributed database management system (DBMS). It supports 6 concurrency control algorithms.
This testbed is based on the DBx1000 system, whose concurrency control scalability study can be found in the following paper:

DBMS configurations can be changed in the config.h file. Please refer to README for the meaning of each configuration. Here we only list several most important ones.
NODE_CNT : Number of server nodes in the database
THREAD_CNT : Number of worker threads running per server
WORKLOAD : Supported workloads include YCSB and TPCC
CC_ALG : Concurrency control algorithm. Six algorithms are supported
(NO_WAIT, WAIT_DIE, TIMESTAMP, MVCC, OCC, CALVIN)
MAX_TXN_IN_FLIGHT : Maximum number of active transactions at each server at a given time
DONE_TIMER : Amount of time to run experiment
Configurations can also be specified as command argument at runtime. Run the following command for a full list of program argument.
./rundb -h
The DBMS can be run with
./rundb -nid[N]
./runcl -nid[M]
where N and M are the ID of a server and client, respectively
