Re: Reconciliation IDsþ

2009-01-23 Thread Peter Romain
You are right in that you can do it all in one job and if this suits your
business then this would be the way to go. It's the way that the
out-of-the-box rules for BMC discovery tools work.

However, using a staging dataset is still in BMCs best practice
recommendations - see the Concepts  Best Practices Guide for CMDB 2.1
Page 87. The paragraph says:

Instead of merging multiple discovery sources directly into your production
dataset, merge them into a “consolidated discovery” dataset first. You can
compare this against your production dataset and use the results to generate
change requests or exception reports for any discrepancies.

For flexibility in the future I would always implement a staging dataset
unless there was a compelling reason not to.

Cheers

Peter





 From what I recall from training, that was a best practice before CMDB 2.
 They recommended NOT doing that in CMDB 2 training for performance
 reasons.

 Otherwise, I'm not sure I see a point in creating separate rules for
 determine the best-of-the-best and then having another set of rules for
 reconciling into Gold.  It keeps track of where it gets each attribute
 from, so there's no need to have another reconciliation job to determine
 which one is best, because it will simply use the best one as defined by
 your precedence rules either way.

 Concerning your last point, perhaps I haven't done enough recon work, but
 it seems you're either going to have to add your staging dataset to the
 recon rules for your new data source, or you're going to add your Gold
 dataset.  That seems like a wash either way.  Then again, perhaps I'm just
 missing something.

 BMC best practice is to merge multiple CI sources into a staging dataset
 before merging into production.

 This allows you to keep the recon rules creating the best-of-the-best
 imported data separate from the business recon rules you use to update
 your golden dataset.

 It also makes it easier to add new data sources as you don't need to
 include the golden dataset in each of the individual import recon rules.

 Of course, it increases the number of CIs but I think that's a price worth
 paying to keep things manageable.


 Why are you merging A and B into C and then C into Gold rather than
 merging A and B (and perhaps C depending on whether it has any of its
 own
 data) directly into Gold?  Which version of the CMDB are you using?  If
 you're on version 2 or higher, it keeps track of which dataset each
 attribute came from, so it still applies all of your precedence rules
 regardless of what order you merge the different datasets into Gold.

 Hello,

 I am having a bit of an issue. I have two datasets A and B. I use the
 Reconciliation Engine to merge attributes of these two to C. This works
 fine. However when i try to Reconcile C to the Gold Dataset it doesn't
 work
 as C already has a Reconciliation ID. Is there any way around this?

 Thanks,
 Sean
