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

48 9/ Metric Extensions

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 for patches and requirements

52 10/ AWR Warehouse (AWRW)

53 10/ AWR Warehouse (AWRW)
