- 24. Top 10 Features for DBAs
- 25. 1/ Database Lifecycle Management ■ Database Patching & Updates ▪ Patch Types — PSU — CPU — One-offs — Opatch ▪ Manual patching — Time consuming — Complex — Risky — Requires downtime
- 26. 1/ Database Lifecycle Management ■ Database Upgrades ▪ Upgrades can be scary — Pre-requisites — Backups — Down-time — Cross-fingers
- 27. 1/ Database Lifecycle Management ■ Database Patching & Updates ▪ Use Patch Plans ▪ Out of Place Patching support ▪ Integrates with MOS
- 28. 1/ Database Lifecycle Management
- 29. 1/ Database Lifecycle Management ■ Database Patching & Updates ▪ 5 Step Process to patch many DBs — Patch Description — Select the patches to apply and the targets — Deployment options — Patch Validation & Analysis — Review and Deploy ▪ More automation with EMCLI — emcli submit_patch_plan
- 30. 2/ Real-Time Database Operations Monitoring ■ Simple Statements ▪ SQL Monitoring ▪ PL/SQL Monitoring ■ Composite Database Operations ▪ Enabled by default when STATISTICS_LEVEL=TYPICAL/ALL ■ Define DB Operation ▪ DBMS_SQL_MONITOR.BEGIN_OPERATION ▪ DBMS_SQL_MONITOR.END_OPERATION
- 31. 2/ Real-Time Database Operations Monitoring ■ SQL Monitoring
- 32. 3/ EM Command Line Interface ■ Turbo charges EM! ■ Enables Script Automation ■ Install from OEM Console ■ Standard or Advanced with Scripting Option
- 33. 3/ EM Command Line Interface
- 34. 3/ EM Command Line Interface • emcli help • emcli verb help
- 35. 4/ ASH Analytics ■ Multi-dimensional view of ASH data ■ DB-Time Analysis ■ Top Activity + ▪ Resize sample window ▪ More dimensions ▪ Load map tree
- 36. 4/ ASH Analytics
- 37. 5/ Backup & Recovery When I ask the sysadmins, “The backups are making it to tape, right?” -DBA Reactions
- 38. 5/ Backup & Recovery ■ RMAN Backup ▪ Target-based RMAN backup — Wizard-driven interface — Oracle-Suggested or Customized Backup ▪ Job System based RMAN backup — Use existing RMAN scripts ▪ Group Backups using deployment procedure — Backup multiple databases, homes and filesystems in a single operation
- 39. 5/ Backup & Recovery
- 40. 6/ Corrective Actions ■ Resolve Incidents, Automagically! ■ Automate routine administrative tasks ■ Triggered in response to metric alerts ■ Runs on the target on which alerts are triggered ■ Agent-side response actions can execute single commands or scripts on host
- 41. 7/ Automatic Database Diagnostics Monitor ADDM Compare Period ADDM “Why is the database slower today than yesterday?” Compares database activity over two periods of time
- 42. 7/ Automatic Database Diagnostics Monitor ADDM ■ Real-Time ADDM ▪ Analyzes hung or very slow DB ▪ Finds sources of contention ▪ Performs DB Time Analysis ▪ Uses 2 connection modes — Normal JDBC connection — Latch-less connection ▪ Enhanced Real-Time ADDM (DB 12c)
- 43. 7/ Automatic Database Diagnostics Monitor ADDM Real-time ADDM Active Reports
- 44. 8/ Database-as-a-Service ■ Schema-as-a-Service ■ DBCA Template ■ RMAN Backup ■ Snap Clone ▪ Storage Agnostic (ZFS) ▪ Vendor Specific (NetApp, Oracle ZFSSA, EMC) ■ Pluggable Databases (12c)
- 45. 8/ Database-as-a-Service ■ Database-as-a-Service
- 46. 8/ Database-as-a-Service ■ Database-as-a-Service
- 47. 9/ Metric Extensions Not satisfied with out-of-the-box metrics? BYOM… …Build Your Own Metrics
- 49. 9/ Metric Extensions • Many out-‐of-‐the box metrics available • If there isn’t you can create your own • Create using adapters • SQL • PL/SQL • Shell Scripts • Useful for re-‐using exisLng scripts
- 50. 9/ Metric Extensions Example • Flash Recovery Area (FRA) being used • Archived Used (%) doesn’t trigger • Recovery Area (%) Used not modifiable • Warning 85% • CriLcal 97% • Create new FRA Used (%) Metric • See New EM12c Extensibility Exchange for examples
- 51. 10/ AWR Warehouse (AWRW) ■ Used for consolidation of AWR from multiple databases ■ Provides long term historical information for AWR ■ Data is moved from source to targets system via ETL jobs ■ Retention period can be modified ■ See MOS note 1907335.1 for patches and requirements
