Instances of ACS

• Designed so that more than one developer can run ACS on the same machine

• Instances are numbers: 0 - 9

• Resources (ports) configuration for:– services

– manager

• Clients: status, ping, logout from manager, shutdown, disconnect, …

• Components: status, …


ALMA Project

Object Explorer

• Generic tool for browsing BACI aware distributed objects in the system:– very useful in development phase: testing & debugging

– hierarchically browsing components, seeing their properties/characteristics, invoking commands, creating monitors, …

• Command Center:Tools-> Object Explorer...

• cmd line: objexp
