31 Oracle Exadata Monitoring and Management Best Practices Presented by : Rick Shawver October 2015

32 Exadata Monitoring with 12c Wells Fargo DAN Infrastructure Team We build, support, and manage standardized, shared environments for Oracle OID, RMAN, ASM, SAN, NAS, Oracle s/w stack, Grid Control Targets split between two Grid Control environments (prod and nonprod) Directly support approximately 640 hosts, 160 clusters, 1756 databases, 5102 instances, etc Same and versions across the environment Redhat 5/6, Solaris 10/11, OEL 6 (Exadata), Oracle ZBA We provide triage support for all of the above to the LOB DBA s So what s new? We got our first 14 Exadata appliances! Target usage initially for a few critical applications Shared environments Predominately used for OLTP Now we re building on our history of lessons learned to develop compatible standards that can be applied to the Exadata architecture * In our new role as DBMA s we have added patching, upgrading, managing the Exadata infrastructure 32

33 Exadata Monitoring with 12c The Exadata plugin exposes the Appliance Components * Monitoring complexity is increased if the Exadata platform is used to house databases for multiple LOB s and the Exadata infrastructure is maintained by a yet another team. 33

34 Exadata Monitoring with 12c The Exadata plugin displays all components of the Appliance Components. Some examples: * The Exadata cell information is a component that the Application DBA team wanted access to. This required additional group and incident rule setup. 34

35 Exadata Monitoring with 12c * 35

36 The 12c target type oracle_dbmachine is a composite target that includes ALL targets within the Exadata environment. Items to consider when setting up Exadata monitoring: In a typical group/role security model, adding the Exadata Database Machine to any group, adds all databases as well as all platform related targets such as cell, iloms, pdus, network, etc. LOB support teams require 12c access to their databases and shared targets such as host, agents, crs, cells, asm, listeners, but NOT iloms, pdus, network, etc. There are cases where databases such as fsdb require monitoring with alerts directed to the Exadata support team. 36

37 How Wellsfargo handles this unique separation of duty and alert notifications Create a separate 12c group for those Exadata targets that the LOB teams will have access to. This includes the Exadata Storage Server Grid and the Exadata Storage Servers Create two 12c groups for the Exadata support team Group 1 contains all platform related Exadata type excluding the DB Machine. Group 2 contains only the Top Level DB Machine targets. This is used for the Incident rule alerting on the overall DB Machine status. Place the databases that each LOB and Exadata support teams are responsible for in groups that each team has full control over. Create 12c Roles that contain the appropriate groups for each support team 37

38 Notice both groups appear to have the same targets. However group 2 only contains: There is an automatic expansion of the DB Machine targets. If the DB Machines are added to an Incident Rule, ALL targets on the DB Machine will be included. 38

39 There are Incident rules for Exadata targets in one rule set, AND a specific DB Machine Ruleset. 39

40 The two Exadata rules for the Exadata Support team used two different groups: 40

41 The typical setup for LOB support groups (Those supporting DBs on Exadata) required view access into the Exadata Cells A second LOB group was needed because view access is given to the cell targets. The main LOB group propagates full for all targets included. 41

42 The LOB Exadata group is only given View access to the cells. The role these groups are in get assigned to the DBA s in that LOB. e.g. View Role: LENDING_CORE_ROLE 42

43 The LOB rules also include a specific rule for cells monitoring. 43

44 The Exadata Plugin gives a detailed look into the setup and health of an Exadata environment. However, care must be taken to secure and authorize only those targets that are required for each support role. Monitoring a shared Exadata environment requires: The ability to limit LOB DBA access to those targets they are responsible for. The ability to produce alerts for LOB DBAs that exclude specific platform hardware targets that are the sole responsibility of the Exadata support team. Giving the LOB DBA team a view into the Exadata cells, and allow them to receive alerts for the cells. The ability to alert on the DB Machine target without inundating the Exadata support team with database alerts that should only be sent to the LOB DBA teams. Allow the Exadata support team to receive alerts for databases they are responsible for (such as fsdb). 44

45 Enhancing Exadata 12c Monitoring utilizing Metric Extensions The Exadata Plugin exposes metrics for the Exadata Target Types for monitoring/alerting. New incident rules were created with all out of the box metrics that Oracle defined thresholds for. 45

46 The Exadata Plugin also exposes additional metrics that cannot be used directly for alerting There are metrics that are collected from the Exadata environment, that thresholds cannot be set for. 46

47 In cases where metrics are exposed, but not available for alerting, Repository side Metrics extensions can be used to produce alerts on those metrics that have not be defined with thresholds. Application LOB teams desired additional cell alerting that was not available out of the box, but that could be exposed via Metric Extensions. 47

48 Using Repository side Metric Extensions the desired metrics can be alerted on: Custom repository side Metric Extensions were created and then added to the LOB DBA Incident Rules. 48

49 Repository side Metric Extensions use the metric data that is populated when the Exadata Plugin is deployed: The Repository side Metric Extensions used data that is being captured by the Exadata Plugin. 49

50 Summary: The Exadata Plugin provides the 12c functionality needed to See into and monitor your Appliance. The plugin provides an extensive picture of what your Exadata environment looks like. Providing an easy to understand landscape of all involved components. Performance data for all Exadata components is available either through the GUI or 12c reporting. Monitoring and alerting for all Exadata Target Types can be enabled to ensure stability and reduce risk of outages. 12c allows for very specific Exadata target security for a variety of support roles. 12c Exadata monitoring can easily be extend with Metric Extension to enhance alerting capabilities. 50
