1. CCRC operations issues
Joel confirmed that the fixes from Stuart allow the simulation to run with the T1s as banned sites. A problem with the
ProcessingDB and adding directories was solved by Andrei.
There was a suggestion to clean up the data from the CCRC08 phases but it was agreed to retain in in the short term
to allow the testing of reconstruction and stripping workflows. Joel asked about how the LFN paths are supplied to the
Processing DB, Andy confirmed this is exactly as given by the JobFinalization module.
After requesting a scan of volhcb01 it was discovered that the problem of intermittent Matcher failures was related to
a closed port. Ricardo requested that Andrew change the importing gfalthr exception printout to a warning. Andrew
reported that the failures of the gfalthr module for 1.10.11 are known and a later version of this is in certification.
Roberto agreed to check the status of this module.
Adria and Ricardo have been testing the new proxy machinery with a test machine in PIC. It is hoped to deploy this
on volhcb03 as soon as possible.
Nick summarised that his tests of xrootd at NIKHEF were successful for jobs of around 8hrs. Andrew and Nick agreed
to perform some stress testing of xrootd versus gsidcap with longer duration jobs.
2. Production Status Report
Roberto raised the issue of who should be allowed to submit GGUS tickets. Joel suggested all VOMS production role
should be allowed to submit tickets. GGUS supporting VOMS will be available in October but in the meantime Roberto
was asked to extract the list of VOMS production role DNs ( ACTION: Roberto ). Joel mentioned that the status at
IN2P3 is still unclear as some jobs continue to become stalled. The pending release of dCache to fix this problem is
expected next week.
3. DIRAC3 tasks
Ricardo raised the question of whether Launchpad should be used, it was suggested that the developers evaluate the
usage of LaunchPad and check whether it could feasibly be installed at CERN.
