What is In-Database Archiving in Oracle 12c and Why You Still Need a Database Archiving Solution to Complement It (Part 2)

In my last blog on this topic, I discussed several areas where a database archiving solution can complement or help you to better leverage the Oracle In-Database Archiving feature.  For an introduction of what the new In-Database Archiving feature in Oracle 12c is, refer to Part 1 of my blog on this topic.

Here, I will discuss additional areas where a database archiving solution can complement the new Oracle In-Database Archiving feature:

  • Graphical UI for ease of administration – In database archiving is currently a technical feature of Oracle database, and not easily visible or mange-able outside of the DBA persona.   This is where a database archiving solution provides a more comprehensive set of graphical user interfaces (GUI) that makes this feature easier to monitor and manage. 
  • Enabling application of In-Database Archiving for packaged applications and complex data models – Concepts of business entities or transactional records composed of related tables to maintain data and referential integrity as you archive, move, purge, and retain data, as well as business rules to determine when data has become inactive and can therefore be safely archived allow DBAs to apply this new Oracle feature to more complex data models.  Also, the availability of application accelerators (prebuilt metadata of business entities and business rules for packaged applications) enables the application of In-Database Archiving to packaged applications like Oracle E-Business Suite, PeopleSoft, Siebel, and JD Edwards

What is In-Database Archiving in Oracle 12c and Why You Still Need a Database Archiving Solution to Complement It (Part 1)

What is the new In-Database Archiving in the latest Oracle 12c release?

On June 25, 2013, Oracle introduced a new feature called In-Database Archiving with its new release of Oracle 12.  “In-Database Archiving enables you to archive rows within a table by marking them as inactive. These inactive rows are in the database and can be optimized using compression, but are not visible to an application. The data in these rows is available for compliance purposes if needed by setting a session parameter. With In-Database Archiving you can store more data for a longer period of time within a single database, without compromising application performance. Archived data can be compressed to help improve backup performance, and updates to archived data can be deferred during application upgrades to improve the performance of upgrades.”

This is an Oracle specific feature and does not apply to other databases.

Series: Architecting A Database Archiving Solution Part 3: End User Access & Performance Expectations

In my previous blog as part of the series, architecting a database archiving solution, we discussed the major architecture components.  In this session, we will focus on how end user access requirements and expected performance service levels drive the core of an architecture discussion.

End user access requirements can be determined by answering the following questions.  When data is archived from a source database:

  • How long does the archived data need to be retained? The longer the retention period, the more the solution architecture needs to account for potentially significant data volumes and technology upgrades or obsolescence. This will determine cost factors of keeping data online in a database or an archive file, versus nearline or offline on other media such as tape. (more…)

Architecting A Database Archiving Solution Part 2: The Anatomy Of A Database Archiving Solution

Before we can go into more details on how to architect a database archiving solution, let’s review at a high level the major components of a database archiving solution.  In general, a database archiving solution is comprised of four key pieces – application metadata, a policy engine, an archive repository and an archive access layer.
Application Metadata – This component contains information that is used to define what tables will participate in a database archiving activity.  It stores the relationships between those tables, including database or application level constraints and any criteria that needs to be considered when selecting data that will be archived.  The metadata for packaged applications, such as Oracle E-Business Suite, PeopleSoft, or SAP can usually be purchased in pre-populated repositories, such as Informatica’s Application Accelerators for Data Archive to speed implementation times.

Policy Engine – This component is where business users define their retention policies in terms of time durations and possibly other related rules (i.e. keep all financial data for current quarter plus seven years and the general and sub ledgers must have a status of “Closed”).  The policy engine is also responsible for executing the policy within the database, and moving data to a configured archive repository.  This involves translating the policy and metadata into structured query language that the database understands (SELECT * from TABLE A where COLUMN 1 > 2 years and COLUMN 2 = “Closed”).  Depending on the policy, users may want to move the data to an archive (meaning it is removed from the source application) or just create a copy in the archive.  The policy engine takes care of all those steps.

Archive Repository – This stores the database archive records.  The choices for the repository vary and will be determined based on a number of factors typically driven from end user archive access requirements (we will discuss this in the next blog).  Some of these choices include another archive database, highly compressed query-able archive files, XML files to name a few.

Archive Access Layer – This is the mechanism that makes the database archive accessible either to a native application, a standard business reporting tool, or a data discovery portal.   Again, these options vary and will be determined based on the end user access requirements and the technology standards in the organizations data center.

In the next series, we will discuss how End User Access and Performance Requirements impact the selection of these components in further detail.

Classifying Database Data For ILM

Classifying databases data for an ILM project requires a process for categorizing and classifying that involves the business owners, Records Management, Security, IT, DBA’s and developers.  In an ideal scenario, a company has documented every single business process down to data flows and database tables.  IT can map database tables to the underlying infrastructure.   Since most of us work in realistic scenarios, here is one approach you can take to classify information without knowing all the interrelations.�

Architecting A Database Archiving Solution

Many of my clients struggle with how to design a database archiving solution. Database archiving is not as clean as email or file archiving. Project owners who have done their research understand why they need an archiving solution: either to address performance degradation or increased costs (or both) due to uncontrolled data volume growth in their production databases. Where help is appreciated is during the planning phase of a project and defining what requirements are critical and how those requirements translate into an archive architecture.

How Many Metadata Repositories Do You Have?

One of the key deliverables for an ILM project that my team is wrapping up is a metadata repository of all the database tables we have applied an ILM solution to.  In this repository, we list the database, schema and table name; what Record Series the data belong to; the corresponding retention period and criteria; business owner; and source information.  Not only will this repository be used to archive and purge data on a regular, operational basis, but it will also be used by Records Management to track Records Retention compliance.
