Pool utilities

Pool information can be in a database or in a XML file (PoolFileCatalog.xml as default) In the catalog files have GUID but only Athena files have a real GUID embedded also into the file

To insert files into the catalog (w/ embedded GUID AND w/o)

pool_insertFileToCatalog _filename_

FCregisterPFN -p _filename_

Remember that all Pool utilities (Coll... ) have the reduntant syntax -src/-dst where the type of collection has to be specified and the extension '.root' of the file should be omitted. To check a TAG (not only) file:

• Lists all the file GUIDS referenced in the collection CollListFileGUID.exe -src sub_collection_1 RootCollection
• Token description CollListToken -src fdr08_reproc_2ev RootCollection

CollListToken is probably the best candidate for output parsing

Normally a TAG file has a main token (EVENT_REFERENCE) with the AOD relerence (DB), probably the TAG file/collection reference (CLID), the event ID (OID). Then there are also a StreamESD_ref and StreamRAW_ref tokens with provenance information (GUID of ESD and AOD files of the event). FDR1 data had a wrong main token (referring TAG file) and an additional StreamAOD_ref token with the AOD's GUID. FDR1rep have StreamESD_ref and StreamRAW_ref all set to NULL.

FDR data have no truth.

Checking files

To inspect AOD or ESD files (number of events and other things...) you can use:

[uct3-edge5] /ecache/marco/reproc_fdr > checkFile.py fdr08_run1.0003071.StreamEgamma.merge.AOD.o1_r24_t3._0001.1

checkFile.py is part of the release (/nfs/osg/app/atlas_app/atlas_rel/13.0.40/AtlasCore/13.0.40/InstallArea/share/bin/../../../Tools/PyUtils/share/checkFile.py)

Setup

On uct3-edge5

export CMTPATH=`pwd`:${CMTPATH}
export CVSROOT=:ext:mambelli@atlas-sw.cern.ch:/atlascvs;export CVS_RSH=ssh;export PATHENA_GRID_SETUP_SH=/share/osg-client/setup.sh 

Code

python directory:

• Client.py: LFC, pandaMon, curl client -> useful func in DDS
• Jobspec.py: DB interface + picling. For? Panda msg? DB storage? coming from?
• LFCClient.py: from? glite LFC client?
• mdclient, mdinterface: USE_TLSLITE, metadata interface, from gLite, org.glite.amga.api-python

share directory:

• extPoolRefs.C: extract POOL references, C macro for ROOT
• fakeAppMgr.py: avoid loading DLL in Athena execution
  • save old one in _theApp
  • AppMgr <- theApp=fakeAppMgr(_theApp)
  • theApp <- EventLoop, OutStreamType from the old one (_theApp)
