mSQL database is used by CODA to store configurations. There is a plan to move to mySQL. To dump mSQL following command was used (in release 2.1 only !!!):

msqldump clasrun > clasrun.sql
msqldump clasdev > clasdev.sql
mysql -h clondb1 -u clasrun daq_clasrun < clasrun.sql
mysql -h clondb1 -u clasrun daq_clasdev < clasdev.sql

NOTE: databases 'daq_clasrun' and 'daq_clasdev' must be created and user 'clasrun' must have an appropriate privileges to access those databases (normally 'ALL_PRIVILEGES'). It can be useful to re-create entire database before filling it up, for example:

mysql -h clondb1 -u clasrun
mysql> drop database daq_clasrun;
mysql> create database daq_clasrun;
mysql> exit

Observed problem: 'BONUS' and 'bonus' recognized by mySQL as identical key; To fix it 'msqldump' was modified to use VARCHAR() BINARY instead of CHAR() for primary keys. Some other changes were applied as well (see code).
