The document describes the limitations of the current Oracle architecture using single instance databases with DataGuard for high availability and discusses the benefits of a new resilient infrastructure using Oracle RAC and ASM. It provides an overview of the components in a demo system including the network, systems, software, storage and shared Oracle homes. It also discusses how NetApp filers can provide storage and snapshots, and how SMO manages consistency when using flex clones of databases.

16. Reduces recovery times

17. Not High Available

18. A resilient new infrastructure

19. Seeing an Oracle cluster in Action

22. Automatic failover (TAF)

24. Automatic failover (TAF)

25. Replicated and redundant storage (ASM)

30. Components: Network

33. Cluster interconnect: low latency

35. Cluster interconnect: low latency!

36. Storage network: huge blocksize huge bandwidth

37. Components: Systems

39. Flexclone

42. Oracle RDBMS 11.1.0.7

43. SnapDrive 4.0

44. SMO 3

47. Oracle RDBMS 11.1.0.7

48. SnapDrive 4.0

50. Or native Java

51. Components: Software

53. GridControl 10.2.0.5 supports all 11g features

54. netmgr, svrctl, dbca are cluster aware

55. 11g can run DBConsole together with GridControl

57. Java/JSP works but may be improved

58. Client tools ( DBArtisan, TOAD): not problem

59. ActiveBatch: Setup needs redesign

60. Storage

63. Virtual Disks are created on the OS and managed by ASM

65. Virtual Disks are created on the OS and managed by ASM

66. Oracle DB uses virtual disks coordinated by ASM

68. It's the most transparent solution

69. It provides better availability

71. It's the most transparent solution

72. It provides better availability

74. Best possible NFS performance

75. No hard mounts Example 1: Sample oranfstab File server: MyNFSServer1 path: 192.168.1.1 path: 192.168.1.2 path: 192.168.1.3 path: 192.168.1.4 export: /vol/oradata1 mount: /mnt/oradata1 Example 2: Enabling the Direct NFS Client ODM Library prompt> cd $ORACLE_HOME/lib prompt> cp libodm11.so libodm11.so_stub prompt> ln –s libnfsodm11.so libodm11.so

77. Reduces maintenance

78. Reduces disk space requirements

79. Can be a SPOF;

80. So let's have a shared home per site. Quest for the home of the Oracle The home of Oracle

82. Filer fun

84. SMO coordinates and maintains consistency

86. SMO coordinates and maintains consistency

87. SMO creates working copies of running databases using FlexClones

88. Source control integration Applying project changes to the new (cloned) database > svn diff --summarize --old=http://svn/CJO/trunk/sql > --new=http://svn/cjo/branches/ProjectA/sql A oracjoc#table1.sql M oracjoc#function2.sql > cat oracjoc#table1.sql oracjoc#function2.sql > new_uat.sql > sqlplus oradba@cjouat @new_uat.sql
