  1. Replication Service Evolution Data replication workshop 3.06.2014

  2. Outline • WWHWW

  3. What we would like to change? Data replication workshop 3.06.2014 • Streams => GoldenGate12c • Conditions data between online-offline • Conditions data between offline-T1s • … • DataGuard services stay unchanged

  4. Why to change now? Data replication workshop 3.06.2014 • LS1 is a good occasion to introduce changes • Streams are in maintenance mode • still supported • no enhancements and no new database features will be adopted • Lets follow new trends and Oracle recommendations • Expertise in GoldenGate opens new possibilities • zero-downtime migrations/upgrades • enables data integration with other non-Oracle database

  5. Are our workloads ready for GoldenGate? Data replication workshop 3.06.2014 • (Native) DDL replication (>=11.2.0.4) • Table creation, granting of user privileges • Data filtering on schema and table name level • Remote configuration and management of replication processes • Proactive and reactive monitoring • (See Lorena’s and Maciej presentation tomorrow) • DDL handler at target database • Not really needed for conditions data • Will be available at the end of this year

  6. Are we ready for GoldenGate Data replication workshop 3.06.2014 • Functional test • Performance test • Long distance tests (with T1s) • Long term stability tests • Tests with production data (ATLASCond) • Optimize networking parameters • Long term test with production data • Local and long distance

  7. How? Data replication workshop 3.06.2014 • Central GoldenGate installation • All GoldenGate software installed on a two-node cluster • Processes operate on databases remotely • All binaries & configuration stored on NAS volumes • All monitoring agents installed on the cluster • Cluster in master-slave configuration • With automatic failover

  8. Central GoldenGate installation Replica databases • GG processes • monitoring agents Source databases WAN A’ Central GG servers A A” B B’ C NAS storage with config and trail files C’ Data replication workshop 3.06.2014

  9. Central GoldenGate installation Data replication workshop 3.06.2014 • Easier deployment and management • Everything in one place => easy hardware migration • Installation of GG software on each db server is not needed • Additional integration with RAC is not need (except central service) • No need of running datapump process (from GG stack) • Single trail files (local) copy =>less storage needed • Improved security • No need of additional port opening on replica sites • Simplified deployment of GG monitoring • enables using of Oracle EM plugin to monitor entire environment • Better performanceover WAN (T0->T1s) measured

  10. How on the D-Day? Data replication workshop 3.06.2014 0) ConfigureGoldenGate processes 1) StartGoldenGate extraction processes 2) Stop Streams processes 3) StartGoldenGatereplicat process *) Keep Streams configuration switched off Impact: less than 1 hour of downtime

  11. Who does what? Data replication workshop 3.06.2014 • Experiment • Gives a green light • Support the testing (if possible) • T0 • Central installation of GG cluster • Central installation of monitoring • Deploy of initial configuration • Long term: administration of online-offline replication • Long term: co-administration of online-T1s replication • T1s • Continue long distance tests • Upgrade to 11.2.0.4 (almost done) • Re-instantiation of data (if needed) • Update firewall port configuration • Register on GG monitoring tool • Long term: co-administer of offline-T1s replication

  12. When to change? (proposal) Data replication workshop 3.06.2014 Long term tests with production data (T0->T1s) June ATONR & ATLR compatibility update max: 1stweek of July GoldenGate for online-offline (condDB) week of 21st of July GoldenGate for offline-T1s 1st week of September

  13. THANK YOU! Data replication workshop 3.06.2014
