COD Duties Rotations of 10 federations/teams -- 1/5 weeks. Quarterly face-to-face meetings to update tools, procedures and uniformize working habits. =================================== 10 federations over 18 months in EGEE-I Working groups for over 18 months now….

There is more to it …. Straightforward mandate working groups: GSTAT -- TW, SAM -- CERN, SAMAP – CE, topped by - Tools for Improvement for COD, TIC – CE (EGEE’07)

Working groups mandate - Integration of the existing tools CIC– FR Integration platform of all COD tools to ease-up the daily operational job - Improvement of BEST PRACTICES -- DE-CH Identifity, raise and analyse with COD how to have homogeneous operations  - Release of updated documentation OPM –SE Documentation under constant evolution - Set-up of Failover Mechanisms for GRID CORE SERVICES – SWE, What is done at a federation level, what is done at the project level (need help from JShiers group), what could be done (operational point of view) and what is needed at the ROC/Site level (from a m/w point of view). - Set-up of High Availability strategy of the operational tools for CODs FAILOVER– IT

EGEE Failover: purpose Propose, implement and document failover procedures for the collaboration, management and monitoring tools used in EGEE/WLCG Grid. –Solution is based on DNS and consists in: mapping the service name to one or more destinations update this mapping whenever some failure is detected Geographical failover for the EGEE-WLCG Grid collaboration tools –CHEP 2007, Victoria BC, Canada (September 2007)

How the system works: DNS switch

COD Work aspects to keep in EGEE IIII Dedication : Working groups recognized within federations to provide expertise and by federations to make the needs come to the central operations. Collaboration : Up to now, each federation had found a way to contribute actively to improve their COD work environment, when not proactively leading a working group. Also, each person/tool developper/expert recognized as of « global interest » eventhough out of COD scope has been integrated happily in this « closed community », e.g SAMAP  TIC scope to monitor this aspect with Nagios prototype for example. Flexibility : Purpose of the groups to evolve together with their mandate with time and the upcoming of the needs e.g. Core grid services HA, EGI Anticipation : e.g. Strategy of the Operational Failover Working Group. Experiment : e.g regionalisation of tools and the future modular « NGI dashboards » to widen the CE 1rst line support experience.

COD Work aspects to make evolve in EGEE IIII Mandate and Assessment of the COD activity  Integration of NDGF/NE as a COD team – other teams ?  Catch-all and global operations center -- what core services are to be monitored centrally, and how to monitor them and how to properly switch to backup -- How to aggregate local data and what local data would be concerned  Assess metrics in order to assess the most problematic m/w components, recurrently unreliable sites  Operational tools reliability assessment /ENOC test as a start base?  Strenghten need on HA/Failover of operational tools and grid core services Vision of the COD tools long-term evolution : 1 set of tools /federation + aggregation? Which set of tools is to be regionalized ? SAM, GOC DB, COD? what else? How are they going to interact => need for a global schema, NOW.

COD Work aspects to make evolve in EGEE IIII Leverage on « project labeled » tools in order for operational use-cases for not to remain « pending ».  developements strategy/priorities are coherent. -- data workflow – synch GOCDB/BDII/SAM/COD -- development strategy – depends on the stretegy of the COD tools long-term evolution -- priority decision workflow – Who and how to drive the « project labeled » tools requests priority for operational use-cases for not to remain « pending ». - critical tests monitoring/accounting or ARC CE. - ca update procedure, - need for SAM failover…  staffing is adequate for proper reactivity not only for bugfix. Interoperability/interoperations (item to be followed up) –OSG : rather informal for the moment, BUT NOW, users do have problems and sites are the relay of their users cf GGUS ticket –NDGF : existing critical test monitoring ? and what are the consequences on operational procedures?

Conclusions and References Where, how, when do we adress these topics?? Some can be adressed here or can be thought at at COD meetings, some are relevant to OCC/ROC first and COD working groups can then make suggestions/recommendations.
