Planning Database as a Service Implementation Project

By Nilesh Agrawal

People, process and planning are the three key elements to success in a private cloud journey. Some common questions i hear from field/customers often relates to tasks involved in setting up Database-as-a-Service(DBaaS) using Oracle Enterprise Manager 12c from scratch and how these tasks are mapped to current IT roles and responsibilities - overall list of activities that needs to be performed to setup and achieve DBaaS and who does what during the implementation process.

In terms of roles, responsibilities and users, you will map to these categories

  • Project Manager is responsible for working with all stakeholders, project team and coordinating in planning and delivering DBaaS implementation project
  • EM Admin sets ups Cloud management infrastructure and is responsible for overall EM 12c installation/configuration and Administration
  • Cloud Admins are responsible for managing the Cloud infrastructure(Servers, Network, Storage) and related Administration
  • SSA Admins or Cloud DBAs are responsible for Self Service portal setup, managing quotas, policies, target DBs S/W provisioning/ongoing Administration
  • SSA Users or End users of Cloud who actually requests for DB instances to be rapidly provisioned on-demand from Self Service portal

Here is a sample Work-breakdown structure(WBS) listing down tasks involved and with individual owners mapped. Note - we have all type of use cases covered in the plan (DBCA, RMAN, Schema as a Service, Snap Clone) and you can pick up any or mix or all of these tasks in your plan depending on your use cases and requirements for implementing DBaaS -

D. Setting up High Availability
Configure Repository For High Availability Enable Repository as per database high availability best practices.
Configure Standby database @ DR site for EM cloud control repository.
Configure repository database as RAC database with 2 or more nodes
Configure OMS for RAC/standby repository
EM Admin
Configure OMS for High Availability See Enterprise Manager Cloud Control Administrator's Guide for Configuring OMS for high availability EM Admin
Configure Agents for High availability See Enterprise Manager Cloud Control Administrator's Guide for Configuring Agents for high availability EM Admin
Test failover strategy Test the Repository and OMS failover to standby site EM Admin
Setup backups Setup back ups for Repository, OMS and agents EM Admin
E. EM 12c Cloud Control Functional configuration
Defining Roles and assigning users Setup Cloud, SSA Admin and SSA User roles and users EM Admin
Setup S/W Library Setup S/W Library for self update/plug-ins/cloud functionality Cloud Admin
Setup Self Update Setup self update to get new and updated capabilities when they become available between official releases EM Admin
Setup required plug-ins on OMS Oracle Cloud Application, Database, Chargeback and Capacity planning, Storage Management Framework (SMF) and Virtualization (VT) plug-ins are required EM Admin

Configure Hosts for Privilege Delegation Configure Hosts for Privilege Delegation. Setup Privilege delegation settings in Cloud Control. Setup named credential for cloud self service EM Admin
Provisioning Oracle RDBMS s/w on Hosts Provision/Configure and add Oracle Home as target in EM12c - Refer to EM 12c Lifecycle Management Admin guide for DB provisioning details.
Optional - If planning to use GI/RAC for cloud services, provision/configure GI/RAC Oracle Homes as targets in EM12c
In case of Exadata, Grid Infrastructure and RAC Database software is  already deployed on compute nodes via OneCommand from Oracle, so SSA  Administrator just needs to discover Oracle Homes and Listener as EM  targets. Databases will be created as and when users request for databases from cloud.
SSA Admin
Configure Listener Configure and add Oracle Database Listener as target in EM12c SSA Admin
F. Exadata Targets Monitoring Configuration in EM (Optional - in case DBaaS setup is on Exadata)
Deploy Agents on compute nodes Deploy Agents on Exadata compute nodes EM Admin
Exadata System Discovery and Configuration Specify host from which Exadata server is being discovered. Specify discovery parameters for Infiniband switches. Specify discovery parameters for associated subsystems, such as ILOM, KVM, Cisco switch. Complete discovery and confirm that all targets have been discovered. Verify that cell groups have been created for cells associated with each database. Verify the targets in the topology view of the Exadata Database Machine system. Navigate the topology and verify the configuration of the each of the targets in the Exadata Database Machine system. EM Admin
Exadata System Alerts, Metrics, Performance Monitoring and Actions This use case will demonstrate the different alerts, metrics monitoring and actions available EM Admin
