Commercial - Oracle, DB2 (from IBM)

opensource -
   sendmail has a quiesce signal handler, but I've never used it

        see sendmail.h
        extern SIGFUNC_DECL     quiesce __P((int));

   Postgres and mysql fake it I think,  You "quiesce" them by having
them do a dump of the database, then the backup picks up the dump.

The key thing is knowing the right word to google for, and the right
word is quiesce.
