I would just like to mention that my proposed solution was not a good idea. Persistence is worth keeping.
Since the merging of the initial configuration and the persistence data is ill-defined, I decided to avoid the problem by using the initial configuration only if persistent storage did not exist yet. I am making the assumption that the standard MIBs are implemented with classes that implement the SerializableManagedObject interface and that isVolatile is false. So far, this seems ok. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Monday, January 04, 2010 3:32 PM To: [email protected] Cc: [email protected] Subject: Re: [SNMP4J] SNMP4J configuration and persistence Correct me if I'm wrong, but AgentConfigManager.configure() reads the configuration file using MOServerPersistence.loadData() which means the configuration file is exactly equivalent to read-only persistence in the current implementation. I'm trying to decide how users will configure the agent USM and VACM. The cheaper the better as long as it is full featured. The configuration file is human-readable so it fits the bill. Unfortunately, the persistence format is binary which makes it hard to predict the combined configuration. Is it common to let the SNMP manager console modify the agent USM/VACM MIBs through SNMP SET requests? If typical agents usually turn off write access to the USM/VACM MIBs, then I might simply turn off persistence for now. -----Original Message----- From: Frank Fock [mailto:[email protected]] Sent: Monday, January 04, 2010 2:09 PM To: Pellerin, Clement Cc: [email protected] Subject: Re: [SNMP4J] SNMP4J configuration and persistence The configurationFactory is also needed if persistent MIB data is available, because (1) not all ManagedObjects may implement the SerializableManagedObject interface (2) a SerializableManagedObject may refuse to load persistent data because its flag isVolatile returns true.
