Editor's Notes
- #7: Configuration Management – detect changes across the environment. Enables standardization/change process management by detecting drift. Database systems Enhanced EMCLI verbs – Manage OEM targets from command-line. Blackouts, jobs, deployment procedures etc. Performance Diagnostics Enhancements- ASH Analytics RAC One Node Support – Manage RAC One node databases Group Backup – backup multiple databases in a single run Real-Time Database Operations Monitoring Active Reports
- #8: New features in 12.1.0.3. Database Lifecycle Management support for Pluggable databases. Advanced EMCLI script option Enhanced configuration search Change Activity Planner allows you to plan, manage and track long running change activities in the datacenters. Usually done using spreadsheets and -Large scale operations like PSU/patch deployment requiring multiple teams -Consolidation for Exadata -Migration and upgrade projects
- #9: Database patching is time consuming – even with opatch auto. Upgrades require lots of testing and manual steps. Also need to minimize downtime to meet SLAs.
- #11: Patch Plans can be done online via MOS integration or offline. MOS credentials should be configured to use online patching. Out of place patching copies the existing oracle home, patches it and then switches the Oracle Home for the for the database. Reduces overall downtime.
- #12: Provide patch name Select the patches to apply and the targets Set deployment options Patch validates that there are no conflicts for the new patches. Also checks that oracle inventory is OK. In case of Clusterware/RAC it checks clusterware status. Review and Deploy

- #14: Database monitoring of application jobs including groups of SQLs and sessions for batch jobs Simple SQL Statements – anything running more than 5 seconds of CPU/IO or running in parallel Identify high resource SQL and PL/SQL Monitor batch jobs such as ETL Monitor and track execution progress More fined grained monitoring of Data Pump Jobs – enabled automatically
- #15: Database monitoring of application jobs including groups of SQLs and sessions for batch jobs Simple SQL Statements – anything running more than 5 seconds of CPU/IO or running in parallel More fined grained monitoring of Data Pump Jobs – enabled automatically
- #16: Enables scripting and automation Interactive mode with Jython (12.1.0.3.0)
- #17: Enables scripting and automation Interactive mode with Jython (12.1.0.3.0)
- #18: Enables scripting and automation Interactive mode with Jython (12.1.0.3.0) See presentations by Ray Smith and Kellyn Pot’vn for more advanced
- #19: View presentations on ASH deep dive by Jim Beresnewicz & Kelly Pot’vn
- #20: D
- #21: Just because we take backups doesn’t mean that it will work.
- #22: Recovery Manager (RMAN) built-in tool for performing database backups and recovery. Integrated with EM12c. Allows granular backup/recovery configurations – Disk-Based Backups Tape-Based Backups Multiple backup Types Full Backup Incremental Backup Incrementally Updated Backup Multiple Backup Modes Tablespace Whole database Datafile Archivelogs
- #23: Recovery Manager (RMAN) built-in tool for performing database backups and recovery. Integrated with EM12c.

- #25: Manually triggered using AWR Data
- #26: Automatic Database Diagnostics Monitor Requires Database Diagnostics and Tuning packs. ADDM uses AWR snapshots and automatically runs every hour Real-time ADDM differs from ADDM is that it access data from ASH buffers i.e. direct connection to SGA. No global resources are used i.e. latches and enqueues. Eliminates database restarts Enhanced Real-Time ADDM runs automatically every 3 seconds to proactively detect performance problems.
- #27: Diagnostics mode connection requires the SYSDBA role Requires deployment of one-time deployment of packages
- #34: Transforms EM12c into a complete 360 view infrastructure management suite – for non-Oracle products.
