I don't know what you mean by 'logical id', but SSID is the subsystem id name of the DB2 instance. SSID can also be the group name if more than one DB2 subsystems are part of a data sharing group. And SQL-id is more or less like a user-id for a user. Hope that clears the confusion. They can't replace each other!
