SAM Postgres database upgrade and migration Wednesday, July 17

WHAT ARE WE DOING?
Computing will be migrating the following SAM Postgres databases to new virtual machines. We will also upgrade these databases to Postgres version 11.2.

  • sam_coupp_prd
  • sam_dune_prd
  • sam_icarus_prd
  • sam_sarc_prd
  • sam_seaquest_prd
  • sam_noble_prd
  • sam_nova_prd

 

WHEN WILL THIS OCCUR?
Wednesday, July 17; 8 a.m. – 4 p.m. Central Time

 

WHAT IS THE IMPACT TO YOU?
The SAM data handling system for the following experiments/projects will be unavailable for about two to four hours within the maintenance window:

  • COUPP
  • DUNE
  • ICARUS
  • SARC
  • SeaQuest
  • Noble Detector R&D
  • NOvA

 

WHAT DO YOU NEED TO DO?
Please be aware of the SAM system downtime for the above experiments/projects and plan accordingly. There will be further communications during the maintenance window once the upgraded database has been tested and your SAM instance is ready for use.
