Core service adoption/upgrade procedure at MPDLMax Planck Digital Library

Pre-requisites for adoption of new core-service

  • latest core-service (decision by dev team if we work with build or RCRights Checking candidate)
    • deployed always on (already exists, practice a bit abandoned?)
  • latest released solutions/code should be run against the latest core-service
    • necessary test data should be ingested for all solutions
    • bug/reports should be forwarded to FIZFachinformationszentrum Karlsruhe
    • solution/service developments allowed only for interface changes
  • no green light from MPDLMax Planck Digital Library side until solutions (latest releases) are running stable
  • FIZFachinformationszentrum Karlsruhe has to have access to test environment for own tests with our data/solutions
  • duration proposed: focused team max 10 - 15 days
  • when can it start: as soon as we have agreed with FIZFachinformationszentrum Karlsruhe on new RCRights Checking candidate test
    • solutions in development are not considered for testing
    • branch of released solution code to be created for these purposes
      • issues with merging afterwards to be checked

Pre-requisites for stable core service

  • feedback from solution developments
  • agree on "stable"
    • already existing features work properly
    • bugs reported in previous versions do not appear again
    • performance is not affected in negative manner
    • if there is a need for migration of core-service data - migration procedure must be tested and run without problems
    • availability is not affected in negative manner (outofmemory errors)

Upgrade procedure

  • make new release of branched solutions (if these are properly tested)
  • QAQuality Assurance
    • deploy solutions on qa
    • deploy core-service on qa
    • last tests (further to be detailed whether) and evtl bug-fixes of solutions
    • send/prepare notifications wherever needed
      • checklist
        • pilots
        • blogs
        • gwdg
