This meetings covers EOSCTA service operations at CERN: minutes, community

 

Rota

• No rota ticket
• Rota should be reassigned in case of impossibility and we need a physical rota token so that the person on rota knows about it.
• CERN Digital Memory project on CTA
  • Finally configuration for test and production
• 2026-02-05: CTA Oracle production patching
  • Performed on time, data starts slowly next week with cosmics
  • During intervention that require CTA service to be down disabling pl does not mess with supply: show service as degraded as usual
    • For partial service intervention: we must disable logical libraries
• Investigate "Failed SQL statement" error putting drives down
  • DB glitch in the middle of the scheduling loop?
