Top 10 Features for DBAs
1/ Database Lifecycle Management
■ Database Patching & Updates ▪ Patch Types
— PSU
— CPU
— One-offs
— Opatch
▪ Manual patching — Time consuming
— Complex
— Risky
— Requires downtime
1/ Database Lifecycle Management
■ Database Upgrades ▪ Upgrades can be scary
— Pre-requisites
— Backups
— Down-time
— Cross-fingers
1/ Database Lifecycle Management
■ Database Patching & Updates ▪ Use Patch Plans ▪ Out of Place Patching support ▪ Integrates with MOS
1/ Database Lifecycle Management
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
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
2/ Real-Time Database Operations Monitoring ■ SQL Monitoring
3/ EM Command Line Interface
■ Turbo charges EM! ■ Enables Script Automation ■ Install from OEM Console ■ Standard or Advanced with Scripting Option
3/ EM Command Line Interface
3/ EM Command Line Interface
• emcli help • emcli verb help
4/ ASH Analytics
■ Multi-dimensional view of ASH data ■ DB-Time Analysis ■ Top Activity +
▪ Resize sample window ▪ More dimensions ▪ Load map tree
4/ ASH Analytics
5/ Backup & Recovery
When I ask the sysadmins, “The backups are making it to tape, right?”
-DBA Reactions
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
5/ Backup & Recovery
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
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
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)
7/ Automatic Database Diagnostics Monitor ADDM
Real-time ADDM Active Reports
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)
8/ Database-as-a-Service
■ Database-as-a-Service

■ Database-as-a-Service
9/ Metric Extensions
Not satisfied with out-of-the-box metrics?
BYOM…
…Build Your Own Metrics
9/ Metric Extensions
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
9/ Metric Extensions
• 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
Example
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
