1 arta  1.1 			SUM Version 2.1 Release Notes:		24May2006
 2           
 3           The V2.1 particulars are:
 4           
 5             *the sum_svc runs on d00 as user production. If you need to start it do:
 6              sum_svc jsoc &
 7           
 8             *the SUMS now runs under Postgres. There is no longer an Oracle server 
 9           running on hmidb.
10           
11             *the t120 tape robot is supported. It is fully populated with 120 
12           tapes and the import/export of tapes to the shelf via the EE door is 
13           supported. All status dislay and operator interaction with the t120 is via
14           the t120view program (soon to be tui - t120 user interface).
15           
16             *tape archiving is implemented. the tapearc program will write all
17           archive pending storage units to tape. The group id of a storage unit is 
18           assigned by DRMS, and is dynamically assigned to an available tape by SUMS.
19           We need to discuss the assingning of group ids to DRMS data series.
20           
21             *Each group id has a retention time of its tapes in the robot. This is defined
22 arta  1.1 in the sum_group table. Values for the different groups has not yet been
23           defined.
24           
25             *Each file written to tape will have an md5cksum calculated and stored in
26           the sum_file table. This is for off-site verification purposes and ad hoc
27           integrity checks.
28           
29             *a disk scrubber runs every 20 mins (configured by
30           /home/jim/cvs/jsoc/tables/sum_rm.cfg.hmidb) and will delete expired delete
31           pending storage units.
32           
33             *The effective date for a SUM data segment to be deleted, or a tape eligible
34           for unload will now be to the hh_mm instead of just the day.
35           
36             *SUM db backup on hmidb is TBD as a Postgres cron job.
37           
38             *All V2.1 SUM storage units created are now considered "real"
39           and will be propagated forward to future releases.
40           
41             *Must be compiled with gcc. icc gives seg fault when this is false:
42                   if(p == q_rd_front)
