Oracle OpenWorld 2013 Schedule

The annual Oracle OpenWorld global technology conference being held in San Francisco, CA is almost upon us. It kicks off September 22 with user group symposiums and runs until September 26. I was lucky enough to be chosen as speaker again this year. I say lucky because I believe there are much better speakers with more interesting topics that should've been accepted over mine. Whatever the reason, I'm happy and I'm looking forward to meeting up with old friends and networking with some of the best technologists and speakers in the world.

Oracle Enterprise Manager Cloud Control 12c and Database As A Service (DBaaS)

The information technology industry has been a tremendous growth in Cloud delivery models for IT services in the past couple of years. More recently, the PaaS service model including Database-as-as-Service (DBaaS) has been gaining traction rapidly. Amazon's RDS public DBaaaS service supports Oracle, MySQL and SQL Server and enable rapid development lifecycles by giving end-users the ability to provision databases on demand in a very short period.
Security and control are two drawbacks seen in public cloud environments. How can this be overcome while delivering the same level of rapid provisioning, elasticity and multi-tenancy for databases? Oracle Enterprise Manager Cloud Control 12c provides a complete lifecycle management framework for databases - from provisioning to patching. The Database Cloud plug-in enables DBaaS for users on premise without the drawbacks of public clouds. If developers want copies of schemas then the Schema-as-a-Service sub-model can enable them to self-pr…

EM12c Partition Maintenance and Stats

In previous versions of Oracle Enterprise Manager you would call the EMD_MAINTENANCE package to execute certain maintenance tasks such as partition maintenance and statistics gathering.

In OEM12c these procedures are replaced by:

The daily_maintenance procedure actually calls gc_interval_partitions and gathers stats on Saturday. Not quite sure why that was hardcoded but I guess they figured that monitoring was least likely to be impacted on that day. If the OEM DBMS jobs are down you can also submit them by logging in the to the repository database as SYSMAN and execute the package:


Note that these procedures are automatically run through scheduled jobs once the job_queueue_ processes parameter is set to a value greater than 0.
