Week of 140818

WLCG Operations Call details

  • At CERN the meeting room is 513 R-068.

  • For remote participation we use the Alcatel system. At 15.00 CE(S)T on Monday and Thursday (by default) do one of the following:
    1. Dial +41227676000 (just 76000 from a CERN office) and enter access code 0119168, or
    2. To have the system call you, click here

  • In case of problems with Alcatel, we will use Vidyo as backup. Instructions can be found here. The SCOD will email the WLCG operations list in case the Vidyo backup should be used.

  • GridPP:
  • IN2P3: NTR
  • JINR: NR
  • KIT: NTR
  • NL-T1: Followup on GGUS:107655 ticket, ie LHCb ticket about brazilian DNs problem. Problem related to double proxy jar files which is fixed now. To activate the change this needs a reboot of dCache (15 mins) which will interrupt all transfers. Questions to experiments when to reboot? Proposed to combine the reboots with another software intervention next week. NL-T1 will post it on GOCDB.
