Subject: [NV-L] Nways Database and NetView database
I have several questions regarding Netview database and Nways Campus
Manager database(LAN, ATM).
(1) Is there any relationship between these two sets of databases? If
I clear up the Nways objectStore database only, Will there be any impact on
>> Nways uses the Netview database, and adds fields and symbols, and sets
>> status in it, etc. It also stores other data in its Ostore database. It
>> populates the Ostore based on the contents of Netview's database. So
>> Netview controls the discovery and Nways works from that. If you clear
>> the Netview database, you should do the same for Nways.
(2) If these two database system are independent of each other, after
I clear out the Nways database, but not NetView's, when will the database
repopulated with device data? restart of cmld?
(2a)Will there be an independent polling on Nways side? Or it will
read data from NetView database and then poll the devices for additional
>> Both. Netview does discovery and IP status polling. The various Nways
>> applications do additional snmp polling for device-specific things.
>> Under smitty cml, you have options to control that polling. Well, for
>> the atm app you can only control the frequency. For the 8250/60 Hub
>> Manager you can control whether it is regular or only done when the
>> Hub view is opened. And the JMAs have a whole 'nother thing. And they
>> all have the equivalent of a demandpoll. But all of this polling is
>> vendor and device specific, not an overlap with Netview polling
(3) In NetView, when the database size is big and adding/deleting
happens quite often, we have tools to compat the database, is there any
in Nways to do similar job ?
>> Yes. Under smitty cml, maintain, there are options to clear the ostore
>> databases for the lan and atm components. Then they get repopulated.
>> I only do that when I think there is something funny going on, or after
>> a restore or major change in the Netview database.
