MCC notes are getting too big to access over low speed connection -
point to note # in case this question is handled wider earlier.
How to make backups of (all) MIR data in non-stop environments ?
(Backup = copy of all data without any loss or inconsistency;
this copy can also be restored)
I've been asked this question recently very often for Ultrix
implementation.
It looks essential that that tools are provided for each of data
storage types (DNS has these) or MCC would provide this capability
(background?).
As I haven't seen a good description of private MIR (pointer please?)
functionality, I wonder if it can/could used for this purpose i.e.
MIR contents could be copied to a specific directory?

HDR FM was the component designed to store data, for subsequent retrieval.
The component known as the Archive FM was anticipated - this FM would
take data out of the MIR and store it away for off-line use, and
perhaps even restore it to the on-line MIR. Additionally, this FM would
purge data, perhaps after archival, from the on-line MIR.
To date, the only capability implemented in the Archive FM is the purge
capability. Sounds like you're voting for this function in a new
release?
The 'miscellaneous' category of the MIR (which initially we called
private data) is for the storage of any stuctured or unstructured data
used by a management module. We give examples of these sorts of things
in the SRM. There are mcc_mir routines available to be used for this
purpose, but of course any i/o, filesystem or database calls can be
used, depending on the structure of the data.
Recently, in DECmcc v1.2, there is a scheme whereby the Instance
portion of the MIR, normally implemented via DECdns, could be (at the
customer's choice) based on a local file, rather than on a global
naming service. For reasons I'm not aware of, this has been referred to
informally (and I hope only internally) as a "private MIR".
For more information about this capability, (and I hope it's in terms
of better terminology) see the MCC v1.2 doc set.

| 2276.2 | Vote for Archive/Restore (a must)! | EEMELI::VALTONEN | Ken tiet�is tulevaisuuden | Mon Feb 10 1992 09:58 | 9 |
Yep, I vote for this functionality for V2.
Data Network management can survive perhaps with existing method
for backup: Exit MCC, backup, restart MCC.
Telecom Network management does not allow this happen - non-stop
management environment with 10+ events/alarms per second requires
additional support (especially when alarm = object/entity).

I would like to record as many votes as I can (at least one for every customer) for making data backup/archive a high priority. My customers feel that they need this functionality. Several of my customers are (or soon will be) running in a 24 hr/day non-stop environment. They cannot afford to have their networks go down and the network management system(s) must be even more reliable than the networks they support. Regards, Glen R. | |||||
| 2276.4 | why isn't DNS sufficient for this? | MCDOUG::MCPHERSON | Save a tree: kill an ISO working group. | Thu Mar 12 1992 12:51 | 8 |
Doesn't DECdns (with multiple servers) provide the capability (non-stop + backup capability) that you're asking for? Someone with more experience with DNS will need to either confirm or refute this, though. /doug | |||||
