... ASM spreads files across all available storage and mirror at the database file level rather than the entire disk level. ASM simplifies the processes of setting up mirroring, adding disks, and removing disks Instead of managing hundreds and possibly thousands of files (as in a large data warehouse), ...

Lab Work: SCADA, OPC and Database Systems
... We will focus on creating 3 different systems as shown in the figure. The 3 different systems will be: 1. Control System 2. Datalogging System 3. Alarm System Note! These 3 systems shall be implemented as separate applications that in theory can be running on different computers. We will use LabVIEW ...
