Revision 1.11  2007/04/04 10:33:36  jgrosseo
1) Storing of files to the Grid is now done _after_ your preprocessors succeeded. This is transparent, which means that you can still use the same functions (Store, StoreReferenceData) to store files to the Grid. However, the Shuttle first stores them locally and transfers them after the preprocessor finished. The return code of these two functions has changed from UInt_t to Bool_t which gives you the success of the storing.
In case of an error with the Grid, the Shuttle will retry the storing later, the preprocessor does not need to be run again.

2) The meaning of the return code of the preprocessor has changed. 0 is now success and any other value means failure. This value is stored in the log and you can use it to keep details about the error condition.

3) New function StoreReferenceFile to _directly_ store a file (without opening it) to the reference storage.

4) The memory usage of the preprocessor is monitored. If it exceeds 2 GB it is terminated.

5) New function AliPreprocessor::ProcessDCS(). If you do not need to have DCS data in all cases, you can skip the processing by implemting this function and returning kFALSE under certain conditions. E.g. if there is a certain run type.
If you always need DCS data (like before), you do not need to implement it.

6) The run type has been added to the monitoring page

Revision 1.10  2007/02/28 10:41:01  acolla
Run type field added in SHUTTLE framework. Run type is read from "run type" logbook and retrieved by
AliPreprocessor::GetRunType() function.
Added some ldap definition files.

Revision 1.8  2007/02/13 11:22:25  acolla
Shuttle getters and setters of main/local OCDB/Reference storages, temp and log
folders moved to AliShuttleInterface

Revision 1.6  2006/11/06 14:22:47  jgrosseo
major update (Alberto)
o) reading of run parameters from the logbook
o) online offline naming conversion
o) standalone DCSclient package

Revision 1.5  2006/10/02 12:58:52  jgrosseo
Small interface change in StoreReferenceData

Revision 1.4  2006/08/08 14:19:07  jgrosseo
Update to shuttle classes (Alberto)

- Possibility to set the full object's path in the Preprocessor's and
Shuttle's  Store functions
- Possibility to extend the object's run validity in the same classes
("startValidity" and "validityInfinite" parameters)
- Implementation of the StoreReferenceData function to store reference
data in a dedicated CDB storage.

Revision 1.3  2006/07/11 12:44:32  jgrosseo
adding parameters for extended validity range of data produced by preprocessor

Revision 1.2  2006/06/06 14:20:05  jgrosseo
o) updated test preprocessor (alberto)
o) added comments to example macro
o) test shuttle implements new interface
