Status of open GGUS tickets

Review of recent / open SIRs and other open service issues

Conditions data access and related services

Database services

  • Experiment reports:
    • ALICE: Testing the use of Active Data Guard in order to replace Streams PVSS replication.
    • ATLAS: new schema ATLAS_CONF_TRIGGER_MC added to replication from CERN to Tier1 sites. ATLAS LFC replication to BNL being investigated.
    • CMS: Move to Active Data Guard (to replace Streams replication) is progressing. Streams apply handler errors due to changes in Oracle 11g.
    • Active Data Guard monitoring being improved.

  • Site reports:
Site Status, recent changes, incidents, ... Planned interventions
BNL ntr None
CNAF    
KIT Migrated the Compass-LFC schema to the new hardware (FTS-cluster) and upgraded this cluster to 11.2.0.3. The migration and upgrade process to 11g is finished at KIT/Gridka. Some problems with communication between FTS-frontend and FTS-DB observed. Probably related to SCAN-IP or SERVICE_NAME request. Working on it. None
IN2P3 Follow-up on upgrade issues with Oracle. Upgrade to 11g eventually next week - being agreed with experiments
PIC ntr None
RAL Follow-up on scan listener issues with Oracle, bug doc 1379498.1. Data Guard configuration running for CASTOR databases. None
SARA    
TRIUMF Compataible parameter updated to 11.2.0.3 None
