 $Log$
+Revision 1.64  2007/11/13 16:15:47  acolla
+DCS map is stored in a file in the temp folder where the detector is processed.
+If the preprocessor fails, the temp folder is not removed. This will help the debugging of the problem.
+
+Revision 1.63  2007/11/02 10:53:16  acolla
+Protection added to AliShuttle::CopyFileLocally
+
+Revision 1.62  2007/10/31 18:23:13  acolla
+Furter developement on the Shuttle:
+
+- Shuttle now connects to the Grid as alidaq. The OCDB and Reference folders
+are now built from /alice/data, e.g.:
+/alice/data/2007/LHC07a/OCDB
+
+the year and LHC period are taken from the Shuttle.
+Raw metadata files are stored by GRP to:
+/alice/data/2007/LHC07a/<runNb>/Raw/RunMetadata.root
+
+- Shuttle sends a mail to DCS experts each time DP retrieval fails.
+
+Revision 1.61  2007/10/30 20:33:51  acolla
+Improved managing of temporary folders, which weren't correctly handled.
+Resolved bug introduced in StoreReferenceFile, which caused SPD preprocessor fail.
+
+Revision 1.60  2007/10/29 18:06:16  acolla
+
+New function StoreRunMetadataFile added to preprocessor and Shuttle interface
+This function can be used by GRP only. It stores raw data tags merged file to the
+raw data folder (e.g. /alice/data/2008/LHC08a/000099999/Raw).
+
+KNOWN ISSUES:
+
+1. Shuttle cannot write to /alice/data/ because it belongs to alidaq. Tag file is stored in /alice/simulation/... for the time being.
+2. Due to a bug in TAlien::Mkdir, the creation of a folder in recursive mode (-p option) does not work. The problem
+has been corrected in the root package on the Shuttle machine.
+
+Revision 1.59  2007/10/05 12:40:55  acolla
+
+Result error code added to AliDCSClient data members (it was "lost" with the new implementation of TMap* GetAliasValues and GetDPValues).
+
+Revision 1.58  2007/09/28 15:27:40  acolla
+
+AliDCSClient "multiSplit" option added in the DCS configuration
+in AliDCSMessage: variable MAX_BODY_SIZE set to 500000
+
 Revision 1.57  2007/09/27 16:53:13  acolla
 Detectors can have more than one AMANDA server. SHUTTLE queries the servers sequentially,
 merges the dcs aliases/DPs in one TMap and sends it to the preprocessor.
