Decommissioning EMI WMS

As discussed at the February and April/May OMBs, we are making plans for decommissioning the WMS and moving to DIRAC.

NGIs provided WMS usage statistics, and in general the usage is relatively low, mainly for local testing

Moderate usage by few VOs:

• NGI_CZ: eli-beams.eu
• NGI_GRNET: see
• NGI_IT: calet.org, compchem, theophys, virgo
• NGI_PL: gaussian, vo.plgrid.pl, vo.nedm.cyfronet
• NGI_UK: mice, t2k.org

EGI contacted these VOs to agree a smooth migration of their activities to DIRAC, only some of them replied till now:

• compchem is already testing DIRAC
• calet.org: discussing with the users the migration to DIRAC. Interested in a webinar on DIRAC.
• mice: enabled on the GridPP DIRAC server

We need the VO feedback for better defining technical details and timeline:

• NGIs with VOs using WMS (not necessarily limited to the VOs above), please contact them to ensure that these VOs have a back-up plan.

WMS servers can be decommissioned as soon as the supported VOs do not need them any more. The proposal is:

• WMS will be removed from production starting from 1st January 2018.
  • VOs have 8 months to find alternatives or migrate to DIRAC
• Considering that this is not an update, the decommission can be performed in few weeks.

IPv6 readiness plans

• • Resource Centres: assess the IPv6 readiness of the site infrastructure (real machines, cloud managers)
    • NGIs/ROCs please start discussing with sites and provide suggestions for the overall plan

Decommissioning of dCache 2.10 and 2.13 (to modify)

• support for the dCache 2.10 ended at December 2016, tickets opened by EGI Operations to track decommissioning
• dCache 2.13 decommissioning procedure started, in June the probes will get CRITICAL, support from dCache ends in July, upgrades to be performed by August
• please upgrade to 2.16, whose support ends on May 2018, or to 3.0
  • take care that the dCache team does not support the upgrade from 2.10 directly to 2.16; only 2.10->2.13 and 2.13->2.16 transitions are supported.
• decommissioning campaign will be started by EGI Operations to monitor the upgrade of the dCache 2.13 instances and follow up with the NGIs/sites at the beginning of August

Missing steps:

• on GOC-DB fill in the webdav URL containing also the VO ops folder, for example: https://darkstorm.cnaf.infn.it:8443/webdav/ops or https://hepgrid11.ph.liv.ac.uk/dpm/ph.liv.ac.uk/home/ops/
  • it corresponds to the value of GLUE2 attribute GLUE2EndpointURL (containing the used port and without the VO folder)
  • follow the HOWTO21 for filling in the information on GOC-DB
• verify that the webdav url (for example: https://darkstorm.cnaf.infn.it:8443/webdav ) is properly accessible
