Hello all,
I am using root 3.05/02 with Geant4.4.1.p01. In an exercise of poor
judgement I hope not to repeat, I was running a simulation with many tens
of millions of events and without saving my data in the interim. The bad
news is that a power loss occurred during a run; the good news is that the
root file was in the process of being written. When I viewed the file,
root had to "recover" the file:
TFile f("simset75.root")
Warning in <TFile::Init>: file simset75.root probably not closed, trying
to recover
Info in <TFile::Recover>: recovered key TList:StreamerInfo at address
64132996
Info in <TFile::Recover>: recovered key TTree:CrystalTree at address
897651719
Warning in <TFile::Init>: successfully recovered 2 keys
I then view the file in a TBrowser, and all appears well. I was hoping
someone out there might be able to help me with these questions: What did
the recovery program do and are there any unexpected repercussions? If i
should run into this in the future, is there a permanent recovery
function? or should I write a function to extract the data and write a new
TTree (so it does not have to recover the file each time)?
Cheers!
Mark
