Since the demands from the business for IT services is non-stop, creating copies of production databases in order to develop, test and deploy new applications can be labor intensive and time consuming. Users may also need to preserve private copies of the database, so that they can go back to a point prior to when a change was made in order to diagnose potential issues. Using Snap Clone, users can create multiple snapshots of the database and “time travel” across these snapshots to access data from any point in time.

Join us for an in-depth technical webcast and learn how Oracle Cloud Management Pack for Oracle Database's capability called Snap Clone, can fundamentally improve the efficiency and agility of administrators and QA Engineers while saving CAPEX on storage. Benefits include:

  • Agile provisioning (~ 2 minutes to provision a 1 TB database)
  • Over 90% storage savings
  • Reduced administrative overhead from integrated lifecycle management

Managing Pluggable Database as a Service: Questions and Answers

Since the launch of Oracle Enterprise Manager 12c Release 3, we have received tons of questions around managing Oracle Multitenant, an Oracle Database 12c Enterprise Edition option, and pluggable databases (PDBs)—more specifically; questions about pluggable database as a service (PDBaaS). In this blog, we provide answers to some of the common questions from people.

Question: What qualifies a database to be pluggable?
Answer: A pluggable database must be a current Oracle Database 12c database, configured for multitenant through a new enterprise edition option called Oracle Multitenant. It delivers a new architecture that allows a multitenant container database (CDB) to hold many pluggable databases (PDBs). An Oracle Database in the old architecture (a “non-CDB”) may be upgraded to the multitenant architecture via a simple process known as “adopting the non-CDB as a PDB”. A PDB is a self-contained, fully functional Oracle Database, and includes its own system, sysaux and user tablespaces. You can learn more about Oracle Multitenant and pluggable database in this whitepaper.

Can the pluggable databases be plugged and unplugged across multiple platforms such as Solaris, AIX, and Linux?
The pluggable database must be endian compatible. Cross endian operations require OGG, Data pump or restore from backup.

In terms of database consolidation, what are the differences between using VMs, dedicated schemas and pluggable databases?
To describe the advantages of using pluggable database vs. other consolidation methods, it can be best illustrated in a simply comparison table.


Comparison of Database as a Service Consolidation Models

Pluggable database combines the best of all the other models and offers excellent consolidation, isolation, manageability and is suitable for any application that is certified to run on Oracle Database 12c. With the other models, we see certain shortcomings. For example, server virtualization offers good isolation but creates compliance and administrative headaches. Schema based consolidation offers ease of management and patching, but limited isolation.

How do you track configuration drift with a pluggable database? I certainly understand drift in the container database, but in what ways would a pluggable database drift from its standard baseline?
This pertains to Configuration Drift Tracking via Oracle Enterprise Manager 12c. One can compare any two Enterprise Manager targets or a complete system such as an Oracle Exadata Database Machine. When you compare at the PDB level, they can differ in the tablespace names, the storage settings of tablespace with same name, or users, etc. Using Oracle Enterprise Manager to track drift, it is particularly useful in comparing difference in your development, testing, and production environments. It is even useful for comparing your standby systems to set standards for compliance requirements.

What is a zone? Is it physical? Regional?
The Oracle Enterprise Manager 12c Cloud resource model involves pooling the same target types where it’s combining similar hosts, databases, hardware or other similar resources in to a zone. Zones can therefore be defined by the boundary of the Cloud and exposed through Oracle Enterprise Manager 12c’s self-service portal. In terms of the pluggable database as a service model, you can create Oracle Multitenant container databases and group them to form a database pool that users can then draw from. When the self-service user provisions a pluggable database, they need to simply specify the Zone where they want to deploy. Internally, Oracle Enterprise Manager uses load or configuration driven algorithms to place the PDB in the right CDB.

What will be the DBA and SYSADMIN role in the pluggable DBaaS environment?
With pluggable databases you have common users and local users as well as common roles and associated privileges and local roles and associated privileges. You can isolate user/role/privilege to the PDB by defining only local user/role/privilege. To leverage the manage many as one, you would define common user/role/privilege to act on all PDBs or a subset of PDBs where the common user has create session privileges within the PDB. You would define DBA roles and SYSADMIN roles based on common and/or local user roles.

What if you need custom configurations on a pluggable database? Once the database is deployed via self-service how do you make changes?
Some parameters are modifiable at the PDB level. You would check v$parameter ISPDB_MODIFIABLE value to determine what can be changed. Some customization can be done at the CDB level; however, they would affect all PDBs for that CDB. Oracle Enterprise Manager’s self-service provides a TNS Connect string to connect to the PDB with the right privilege and execute “ALTER SYSTEM” for the parameters that are permissible to change.

If I'm an application developer and I request a database with a certain pre-defined service level, what level of permissions should I expect with that database? Am I getting DBA or SYSDBA privileges with that request?
It depends on what was negotiated as part of the service definition and associated user/role/privileges defined for that service.

Are the pluggable database as a service capabilities for Oracle Database 12c included in Oracle Enterprise Manager 12c? Do we need a plug-in? Do we need to license Oracle Enterprise Manager 12c Database Management Packs?
You need the Oracle Enterprise Manager 12c database and cloud plug-ins. License-wise; the self-service provisioning from Oracle Enterprise Manager is licensed as part of Cloud Management Pack for Database. The Oracle Multitenant option must be licensed if two or more PDBs are plugged into a single CDB.
Watch this short demo called “Using Pluggable Database as a Service (PDBaaS) Self-Service Portal” for a better understanding of deploying PDBaaS using Oracle Enterprise Manager 12c.

Which Oracle Enterprise Manager 12c Management Packs are required to be able to provide DBaaS?
You need the Oracle Enterprise Manager 12c Cloud Management Pack for Database and Oracle Enterprise Manager 12c Lifecycle Management Pack for Database to do database as a service. Both of which must be licensed.

If you have shared memory and background processes in the container database, how do you allocate server resources to a particular pluggable database? Can you assign specific amount of CPU cycles, RAM and IOPS for a given pluggable database?
SQL execution is scoped to the PDB as identified by the con_id created during session create. In Oracle Database 12c, Resource Manager (RM) has been extended to include support for Oracle Multitenant. Policies may be defined at the PDB level in terms of the simple-yet-powerful concepts of “caps” and “shares” to determine the allocation of resources between PDBs. In this way, resource manager can control allocation of CPU, sessions and parallel execution servers. Additionally, on Oracle Exadata, Resource Manager can also manage IO and network. Memory management currently is implicitly managed through SGA LRU algorithms and CPU share management.

What is the largest number of pluggable databases you can deploy on Oracle Exadata?
Currently the PDB limit per CDB is 252 PDBs. In Oracle Real Application Clusters environments such as Oracle Exadata, the density of PDB consolidation greatly increases as you may have multiple CDBs per physical server and 252 PDBs per CDB. The maximum limit would be bound by compute resource constraints/limits. And as mentioned in the question on Zone, Oracle Enterprise Manager gives an ability to combine multiple CDBs into a Pool and handle transparent placement. The Oracle Enterprise Manager self-service user therefore won’t be exposed to the underlying limit.

Can I use pluggable database as a service if the target database is 9i or 10g?
You would need to migrate the Oracle Database 9i, 10g and 11g databases to Oracle Database 12c non-CDB and convert them into pluggable databases. The architectural changes within Oracle Database 12c are not backward compatible.

Can Active Data Guard be configured for selective pluggable databases from a container database? I do not want all pluggable databases to have a standby.
In the current release, Oracle Active Data Guard operates at the container level, however, PDB annotations are tagged in the redo stream, so PDB operations on the primary are reflected on the standby.

Does RMAN support pluggable databases?
Scheduled backups are at the CDB layer and include all PDBs. Ad-hoc backups can be executed on individual PDBs. Individual PDBs can be restored from backup.

Oracle Enterprise Manager Helps Manage Systems for Gaia Mission

The Italian National Institute of Astrophysics (INAF) has selected Oracle to store, analyze and manage scientific data generated from the European Space Agency's Gaia mission. The mission sets out to provide in-depth 3-D mapping of the Milky Way galaxy over the course of the next 5 years. An estimated 1 petabyte of astronomical data (equivalent to 1 million gigabytes) will be collected and stored in Oracle Database with Oracle Enterprise Manager entrusted to manage the system.

The goal of the Gaia mission will give researchers a better understanding into how the Milky Way was formed and how it has evolved over time. According to Roberto Morbidelli, Scientific Operation Manager at INAF, "Our activity within the Gaia mission will provide a huge volume of information, a very precious heritage of astronomical data that will have to be stored for the whole 21st century and beyond. Oracle has demonstrated in other research contexts that it would be the ideal technological partner to manage scientific projects of this kind of size. Thus we are sure that it will be a successful choice for INAF too. Oracle has been selected for its technology’s reliability, scalability, availability and the appropriate technological evolution planned in the next years; also key was the competence showed by Oracle experts in the development of features useful to our research.”

Oracle Enterprise Manager will be deployed to help manage the multiple Oracle Database instances and Oracle Real Application Clusters. Oracle Enterprise Manager will be used to ensure reliable access to Gaia mission data, allowing for numerous third-party applications and systems that control and verify the correct functioning of satellites and astronomical instruments.

“We are proud to offer our technology to the Gaia mission, an international research project that is of both major importance and high ambition,” said Xavier Verhaeghe, Vice President, Technology & Big Data Oracle EMEA. “INAF’s choice is another confirmation of Oracle’s ability to easily manage the extreme challenges involved in processing petabytes of Big Data."

Announcing: Oracle Enterprise Manager 12c Delivers Advanced Self-Service Automation for Oracle Database 12c Multitenant

New Self-Service Driven Provisioning of Pluggable Databases

Today Oracle announced new capabilities that support managing the full lifecycle of pluggable database as a service in Oracle Enterprise Manager 12c Release 3 (12.1.0.3). This latest release builds on the existing capabilities to provide advanced automation for deploying database as a service using Oracle Database 12c Multitenant option. It takes it one step further by offering pluggable database as a service through Oracle Enterprise Manager 12c self-service portal providing customers with fast provisioning of database cloud services with minimal time and effort.

This is a significant addition to Oracle Enterprise Manager 12c’s existing portfolio of cloud services that includes infrastructure as a service, database as a service, testing as a service, and Java platform as a service. The solution provides a self-service mechanism to provision pluggable databases allowing users to request and access database(s) on-demand. The self-service operations are also enabled through REST APIs allowing customers to integrate with third-party automation systems or their custom enterprise portals.

Benefits

  • Self-service provisioning allows rapid access to pluggable database as a service for hosting or certifying applications on Oracle Database 12c
  • Self-service driven migration to pluggable database as a service in order to migrate a pre-Oracle Database 12c database to a pluggable database as a service model and test the consolidation strategy
  • Single service catalog for all approved pluggable database as a service configurations which helps customers achieve standardization while catering to all applications and users in the enterprise
  • Resource guarantee via database resource manager (and IORM on Oracle Exadata) that enables deployment of mixed workloads in a shared environment
  • Quota, role based access, and policy based management that enforces governance and reduces administrative overhead
  • Chargeback or showback which improves metering and accountability for services consumed by each pluggable database
  • Comprehensive REST APIs that support integration with ticketing or change management systems, and or with other self-service portals
  • Minimal administrative and maintenance overhead through self-managing automation that allows for intelligent placement of pluggable databases

To understand how pluggable database as a service works, watch this quick demo:
