1abfbb60 18 Revision 1.15 2007/12/10 18:29:23 acolla
19 Some log added to the listen mode
20
6a926ad4 21 Revision 1.14 2007/12/07 19:14:36 acolla
22 in AliShuttleTrigger:
23
24 Added automatic collection of new runs on a regular time basis (settable from the configuration)
25
26 in AliShuttleConfig: new members
27
28 - triggerWait: time to wait for DIM trigger (s) before starting automatic collection of new runs
29 - mode: run mode (test, prod) -> used to build log folder (logs or logs_PROD)
30
31 in AliShuttle:
32
33 - logs now stored in logs/#RUN/DET_#RUN.log
34
7d4cf768 35 Revision 1.13 2006/11/16 16:16:48 jgrosseo
36 introducing strict run ordering flag
37 removed giving preprocessor name to preprocessor, they have to know their name themselves ;-)
38
be48e3ea 39 Revision 1.12 2006/10/20 15:22:59 jgrosseo
40 o) Adding time out to the execution of the preprocessors: The Shuttle forks and the parent process monitors the child
41 o) Merging Collect, CollectAll, CollectNew function
42 o) Removing implementation of empty copy constructors (declaration still there!)
43
cb343cfd 44 Revision 1.11 2006/10/02 16:38:39 jgrosseo
45 update (alberto):
46 fixed memory leaks
47 storing of objects that failed to be stored to the grid before
48 interfacing of shuttle status table in daq system
49
2bb7b766 50 Revision 1.10 2006/08/15 10:50:00 jgrosseo
51 effc++ corrections (alberto)
52
4f0ab988 53 Revision 1.9 2006/08/08 14:19:29 jgrosseo
54 Update to shuttle classes (Alberto)
55
56 - Possibility to set the full object's path in the Preprocessor's and
57 Shuttle's Store functions
58 - Possibility to extend the object's run validity in the same classes
59 ("startValidity" and "validityInfinite" parameters)
60 - Implementation of the StoreReferenceData function to store reference
61 data in a dedicated CDB storage.
62
84090f85 63 Revision 1.8 2006/07/21 07:37:20 jgrosseo
64 last run is stored after each run
65
7bfb2090 66 Revision 1.7 2006/07/20 09:54:40 jgrosseo
67 introducing status management: The processing per subdetector is divided into several steps,
68 after each step the status is stored on disk. If the system crashes in any of the steps the Shuttle
69 can keep track of the number of failures and skips further processing after a certain threshold is
70 exceeded. These thresholds can be configured in LDAP.
71
5164a766 72 Revision 1.6 2006/07/19 10:09:55 jgrosseo
73 new configuration, accesst to DAQ FES (Alberto)
74

76 enhanced storing of last sucessfully processed run (alberto)
77
a7160fe9 78 Revision 1.4 2006/07/04 14:59:57 jgrosseo
79 revision of AliDCSValue: Removed wrapper classes, reduced storage size per value by factor 2
80
45a493ce 81 Revision 1.3 2006/06/12 09:11:16 jgrosseo
82 coding conventions (Alberto)
83

85 o) removed files that were moved to STEER
86 o) shuttle updated to follow the new interface (Alberto)

b948db8d 104// 2) asynchronized - Run() - starts listening for DAQ "end of run"
