The current data distribution schema requires 4 instances of PadmeCDR to run simultaneously:

1. Copy of new files from the l1padme3 DAQ data server to the LNF Tier2 disk system

2. Copy of new files from the l1padme4 DAQ data server to the LNF Tier2 disk system

3. Copy of new files from the LNF Tier2 disk system to the CNAF tape library

4. Copy of new files from the LNF Tier2 disk system to the KLOE tape library

To start the four instances you must run the following commands:

cd $HOME/cdr
./PadmeCDR -S DAQ -D LNF -s l1padme3
./PadmeCDR -S DAQ -D LNF -s l1padme4
./PadmeCDR -S LNF -D CNAF
./PadmeCDR -S LNF -D KLOE

The complete syntax of PadmeCDR is

PadmeCDR [-S src_site -D dst_site] [-L site] [-s data_srv] [-i] [-h]
  -S src_site     Source site ['DAQ', 'LNF', 'CNAF']
  -D dst_site     Destination site ['LNF', 'CNAF', 'KLOE']
  -L site         Get list of files at given site ['ALL', 'DAQ', 'LNF', 'CNAF', 'KLOE']
                  ALL will compare content of all sites (SLOW!)
  -s data_srv     Data server from which data are copied ['l1padme3', 'l1padme4']
                  N.B. -s is only used when -S/-L is DAQ
  -i              Run the PadmeCDR server in interactive mode
  -h              Show this help message and exit

Each instance of PadmeCDR will append a full log of its activities to the log/PadmeCDRServer_<SRC>_<DST>.log file. The log files of the four instances are therefore:

log/PadmeCDRServer_DAQ_l1padme3_LNF.log
log/PadmeCDRServer_DAQ_l1padme4_LNF.log
log/PadmeCDRServer_LNF_CNAF.log
log/PadmeCDRServer_LNF_KLOE.log

Note that these log files are updated even when the -i option is selected.

The CDR Manager should also start the CDRMonitor service which will update the CDR page on the DCS monitor system running on l0padme3. CDRMonitor can be started from the CDR directory with the command ./CDRMonitor and will write some log information to log/CDRMonitor.log. Information will then be visible from the DCS monitor system on l0padme3:9090 at page DCS - CDR - CDR_Summary - Summary.
