  platforms on which middleware will be deployed
  and supported
• Approve and initiate deployment of successfully
  tested middleware releases
• Archive reference copies of all deployed
  middleware and associated documentation in a

  user communities, virtual organisations and
  existing national and regional Grid
  infrastructures
• Approve the service level agreements negotiated
  between the RCs and the ROCs.
• Approve connection of new RC once they have
  correctly installed the necessary middleware and
  operational tools

A.Kryukov, Yu.Lazin NA3 Induction Courses,

12
OMC Responsibilities

• Promote the development of cross-trust agreements
  between the various existing Certification
  Authorities (CAs) operating within the EGEE Grid
  community and encourage the establishment of new
  CAs where necessary
• Liaise with user communities and virtual
  organisations to monitor their developing
  requirements
• Hold regular review meetings with representatives
  of the federations managing the contributed
  resources

13
OMC Responsibilities

• Maintain a collective overview of network
  performance and raise any significant issues
  through the appropriate channels
• Participate in international bodies establishing
  standards for the protocols and interfaces
  involved in Grid operations

CIC Core Infrastructure Center

• The Core Infrastructure Centres (CIC) have two
  fundamental roles
• To operate essential grid infrastructure services
  that are not required at each Resource Centre
• To act as a Grid Operations Centre providing
  monitoring and operational troubleshooting
  services.
• In addition they play a crucial role as
  second-level support to the ROCs for operational
  problems.

15
CIC Operate infrastructure services

• VO services New applications communities
  joining the project will negotiate with the OMC
  and CICs for a CIC to operate services on their
  behalf. For VO services this will include the VO
  server itself (either LDAP VO server or VOMS
  service), and may eventually include the
  registration process web server for the VO.
  Responsibility for managing the VO membership
  remains with the VO itself (VO manager).

16
CIC Operate infrastructure services

• VO-specific services This includes database
  services for replica services for a VO (or set of
  VOs), and may include other database services
  depending on the needs of the VO. This set
  includes also Resource Brokers, User Interface
  machines (portals), and perhaps VO-specific or
  general information services.

17
CIC Act as Grid Operations Centre

• Monitoring of sites and services, and proactive
  troubleshooting. This includes verification of
  certificate lifetimes, etc.
• Performance monitoring for example of data
  transfers, job throughput etc. Metrics and
  important parameters to be monitored will be
  developed as part of the CIC program of work.
• Control sites participation in production
  service.
• Regularly monitor the accessibility of
  operational services and resources at Resource
  Centres and take remedial action as necessary..

18
CIC Support to ROCs for operational problems

• The CICs will eventually provide (between them) a
  24x7 operational and support service. If a ROC
  cannot resolve a problem, or it is a problem with
  one of the VO services run by a CIC, or problems
  not related to a specific region the CIC will
  take responsibility for the problem coordination
  and resolution. Similarly if the problem is with
  another organization of network infrastructure it
  will be a CIC that manages the issue.

CIC Other responsibilities

• Operational configuration management and change
  control
• Accounting and resource usage/availability
  monitoring
• Collect, store and make available as appropriate
  operational monitoring and authorisation and
  accounting data from Resource Centres.
• Contribute to release notes, guides, etc
• Feedback for infrastructure improvement

• ROC

21
ROC Resource Operatios Center

• The ROCs are the heart of the operational support
  for the grid infrastructure. They have a key
  role as sources of expert advice and technical
  support in the process of building and operating
  the infrastructure. The ROCs will have the
  expertise to assist the growing number of
  Resource Centres in joining the infrastructure,
  through the deployment of MW releases and the
  development of procedures and capabilities to
  operate those resources.

22
ROC Coordinate and support deployment

• Bring new resources into the infrastructure and
  support their operation within it. The ROC will
  be the first point of contact for each Resource
  Centre and will be the intermediary between the
  resource centre and the OMC central deployment
  coordination team.
• This includes coordination of existing national
  grid infrastructures and how they integrate into
  EGEE. The OMC will participate in the
  negotiation with the national infrastructure (if
  it is separate from the LCG/EGEE activity).

23
ROC Coordinate and support deployment

• Act as source of expert advice and technical
  support in deploying and operating the middleware
  in the RCs. The first line of operational
  support.
• Participate in validating new middleware
  releases. Organise and operate certification
  testbeds within the region,
• Provide resources (from regional RCs) for
  pre-production service.
• Port middleware to specific regional needs (e.g.
  local supercomputers etc.)

24
ROC Coordinate and support operations

• Act as front-line user support
• Act as front-line support for resource centres
• Refer problems to CIC, OMC, or as appropriate
• Operate (or organise) regional grid services as
  necessary. This might include Resource Brokers
  or UIs if there is no appropriate service within
  a CIC.

25
ROC Other responsibilities

• Organising operations training at RCs for the
  system management teams
• Organise tutorials for users in the region. This
  is done in conjunction with NA3.
• Organise formal deliverables, reviewers etc. for
  the project as a whole where region has
  responsibility.
• Contribute to release notes, planning guides,
  execution plans, operations guides, etc of SA1 as
  part of the normal operational activities.
