  9. Agenda • Synergies • Database Architecture • Systems Management • HA • Concepts • Data Guard • Oracle Failsafe • RAC • Active Directory, Visual Studio Integration • Summary

  10. Database Architecture • Thread model, not a port of Oracle’s process architecture • Oracle.exe, 1 process many threads • 3GB (32-bit) or 8TB (64-bit) maximum memory per database instance. VLM support allows >3GB on 32-bit.

  11. 16GB rest of RAM Windows Server 2003 Memory Limits (32-bit) Standard Edition: 4GB Enterprise Edition: 32GB Datacenter Edition: 64GB For O/S, other apps For Kernel 1GB 32-bit: VLM Support SGA 3GBwith AWE Code database threads/ memory

  12. rest of RAM For O/S, other apps For Kernel 1GB 32-bit: VLM Support Memory from AWE calls used for db buffers only. The amount of AWE memory allocated equals db_block_size times db_block_buffers. Extended memory available for db buffers via AWE calls 16GB Oracle operating system process. Normally limited to 3GB of address space. With VLM, Oracle can get up to 64GB of database buffers. Window on db buffers in AWE mem SGA SGA minus db buffers 3GBwith AWE Code

  13. 64-bit • Interoperability between 32-bit clients and 64-bit servers and vice versa • Improved performance, availability and scalability • Timeline • 10.1.0.4 available NOW • 32-bit to 64-bit upgrade process is simple • 32-bit data files are compatible with 64-bit DB • No need to recreate the database • Full export and import not required • Database Upgrade Assistant automates process • Transparent migration for end-user applications • No changes required to existing client applications when running against 64-bit database

  30. HA Concepts • Design for (not all 4) • Performance • Cost • Scalability • Availability • 99.999% is 5 minutes a year • 4 hour • 30 seconds - 5 minutes • Instant ?

  31. Standby - Data Guard Configuration Standby Site A Primary Site • Managed as a single configuration • Primary and standby databases can be Real Application Clusters or single-instance Oracle • Up to nine standby databases supported in a single configuration Standby Site B Broker Physical Standby Database Primary Database Logical Standby Database

  32. Production Database Network Broker Oracle Data Guard Architecture Physical Standby Database Sync or Async Redo Shipping Backup Redo Apply Logical Standby Database Transform Redo to SQL Open for Reports SQLApply Additional Indexes & MVs

  33. Fast-Start Failover Primary Site Standby Site Observer • Data Guard in steady state – transmitting redo • Observer monitoring state of the configuration

  34. Fast-Start Failover Primary Site Standby Site Observer • Disaster strikes the primary – connections lost

  35. Fast-Start Failover Primary Site Standby Site Observer • Observer <=> primary connection times out (timeout threshold configurable) • Observer asks target standby if it is ready to fail over • Observer begins Fast-Start Failover

  36. Fast-Start Failover Primary Site Observer • Target standby automatically becomes new primary

  37. Fast-Start Failover Standby Site Primary Site Observer • After old primary is repaired, Observer re-establishes connection • Observer automatically reinstates old primary to be a new standby • Redo transmission starts from new primary to new standby

  38. Clustering • Fail Safe • provides quick node failover • high availability solution • integrated with Microsoft Cluster Services (MSCS) • Real Application Clusters (RAC) • shared-disk, clustered database • availability, scalability, reliability • Oracle-provided clusterware • Cluster File System (CFS) • Oracle-written file system for shared disks • one software image can be shared by nodes
