[Orca-users] moving orca input files

[RJNiesz at dstoutput.com]

OK, so I guess I took the long way around the block. That's about par for 
me  :)

But I did not ever delete the rrd files on the new server after running 
orca for the fiorst time with all the old data files. This is what I did

Installed new server
Installed orca and all the supporting software
moved all old orcallator files from all clients to new orca server
ran orca
deleted all old orcallator files

At this point I had all my historical data back and all the graphs were 
current

At about midnight last night all the clients transferred a new orcallator 
file to the new orca server, and shortly after that had completed the new 
orca server kicked off orca once again. Once it had completed, all the 
graphs showed was the data from yesterday. All the old data was gone.

I'll go through this process again to make sure I did not blow it 
somewhere. Although this time I will just move over the rrd files. I'll 
let you all know how it goes.

Thanks again,
Russ (California)

You didn't really need to rerun Orca, just moving the RRD files over to 
the new 
machine would have been sufficient.

Are you deleting or moving your RRD files?  That would cause the problem. 
You 
do need the keep these around, because that are binary data stores of the 
data 
that orcallator or procallator gathers.

The only time you need the old source data files is if you delete the RRD 
data 
files or add a new plot definition to your Orca configuration file which 
would 
cause it to reload all the original data files.

Moving old data files out of the way will also speed Orca up.
