Recovering from a failed MCH Shuttle (2)

this is the same thing as Recovering from a failed MCH Shuttle but for another period/run.

During LHC17o period, the MCH Shuttle failed for run 280729 (PHYSICS run), so the corresponding OCDB objects (HV,LV,occupancy and bus patch evolution) were not uploaded.

To recover from this, Chiara Zampolli sent the Shuttle input files : the outputs from the DAs (MCHbpevoDA, MCHoccDA) and the DCS map (for HV and LV) :

~/analysis/2017/LHC17o
❯ tree
.
└── MCH_280729
    ├── DAQ_MCH_280729_BPEVO_mon-DA-MCH-0.shuttle
    ├── DAQ_MCH_280729_OCCUPANCY_mon-DA-MCH-0.shuttle
    └── testDCSMap.root_MCH_1508551372_1508555974.root

Then renamed them to fit what the following macro expect :

~/analysis/2017/LHC17o/MCH_280729
❯ tree
.
├── run000280729_MCH_mon-DA-MCH-0_BPEVO
├── run000280729_MCH_mon-DA-MCH-0_OCCUPANCY
└── testDCSMap.root_MCH_1508551372_1508555974_run280729.root

From there, using the MUON/macros/runMCHShuttleOffline.C macro those files were read in by a Test Shuttle and uploaded to a local OCDB (in effect this macro is “replaying” the MCH Shuttle preprocessors offline). For this to work AliRoot must be built with TestShuttle support (e.g. build a regular AliRoot and do a ccmake . in the build directory, activate the TEST_SHUTTLE option and rebuild). Assuming also that AliRoot-OCDB package has been installed with alibuild and that an AliEn token is available (alien-token-init username).

The result is some files in the AliRoot-OCDB local OCDB :

~/alice/sw/osx_x86-64/AliRoot-OCDB/latest/OCDB/MUON/Calib
❯ find . -name '*280*'
./BPEVO/Run280729_280729_v0_s0.root
./HV/Run280729_280729_v0_s1.root
./LV/Run280729_280729_v0_s0.root
./OccupancyMap/Run280729_280729_v0_s1.root

The OCDB files were then visually checked with the mchview program for occ,hv,lv and with the MUON/macros/MUONBusPatchEvolution.C macro for bpevo

AliCDBManager::Instance()->SetDefaultStorage("local:///Users/laurent/alice/sw/osx_x86-64/AliRoot-OCDB/latest/OCDB")
AliCDBManager::Instance()->SetRun(280729)
.L MUONBusPatchEvolution.C+
AliMergeableCollection* bp = BPEVO(280729,"bpevo280729.root")
PlotStationOccupancies(*bp);

Finally the object were archived and sent to Chiara (via JIRA ticket ALIROOT-7568) for upload to RAW ocdb.
