Setting DB_LGSVR=4,5,6 can record traced LOG which include CONNECTION and DISCONNECTION information, and also include SQL COMMAND, SQL COMMIT, SQL ROLLBACK, ERROR, and SLOW OPERATION.
If you only care about CONNECTION and DISCONNECTION information, or want to make the LOG file grow slowly, you can set DB_ LGSQL=0 in dmconfig.ini.

Note: In old versions, setting DB_LGSRV=4 and DB_LGSQL=0 will not ignore SQL COMMIT, SQL ROLLBACK which cause LOG file grow fast.
