Parity Run Database (also called PVDB) stores run related information using mysql. DB is running on cdaqdb1 (alias of cdaqfs1) and mirrored over to hallcdb (read-only slave of the cdaqdb1 master). There are a-rcdb and c-rcdb for Hall A and Hall C, respectively. It utilizes existing rcdb framework that has been developed and used for Hall D. While we keep the default conditions from the rcdb, we also added some parity conditions such as helicity and spin rotator information. For questions, please contact email@example.com.

adaq user account already exists. Granted ALL privileges on a-rcdb.
DB structure created:
1) Use get_started.py To create both default rcdb condition types and parity default types (defined in parity_rcdb) > python get_started.py Check with rcnd command: > rcnd (should print conditions)
2) To add new conditon types: Use add_condition_type.py Using CLI (rcnd): >rcnd --create my_value --type string --description "This is my value" ConditionType created with name='my_value', type='string', is_many_per_run='False
