Space Manager with LiveReorg

Database capacity optimization in Oracle databases

Deliver capacity optimization, Oracle reorganization and peak performance with ease

Space Manager with LiveReorg™ enables you to reorganize Oracle data, optimize I/O performance, and maximize database capacity. You can prevent application and database downtime by performing online Oracle reorganizations to reclaim space.  The Oracle partitioning tool also allows you to resolve performance issues due to fragmentation when archiving Oracle data. You’ll find this especially useful for business-critical ERP applications, such as Oracle e-Business Suite, Siebel and SAP, where high-transaction volumes require you to routinely archive data.


Oracle reorganization and space reclamation

  • Reorganizes data to reclaim your wasted space and optimize your database capacity and performance on archived tables, eliminating the need to buy additional disk space.
  • Prevents your organization from experiencing application and database downtime by performing online reorganizations.
  • Determines indexes and tables to reorganize data. Enables you to perform proactive analysis and planning by reclaiming maximum space and tracking historical reorganization activity.
  • Supports multiple datatypes and objects for standard and live reorgs, including individual partitions, domain indexes, user-defined datatypes, and tables with both LOB datatypes and LONG columns.
  • Automatically resumes script execution from point of failure or clean up of residual objects by providing restart and clean-up capabilities for failed reorganization scripts.

Database capacity optimization

  • Using simple charts, easily view existing space usage and future growth in databases that use the same storage resources.
  • Estimate your organization’s future storage needs based on detailed trend charts showing historical growth rates, as well as hypothetical “what if” scenarios.
  • Quickly determine where to utilize space more efficiently with alerts on emerging issues, such as limited free space or space reclamation opportunities.

Oracle partitioning

  • Use a built-in partitioning wizard to minimize downtime by partitioning objects live, while users and applications remain online.
  • Partition, repartition, and remove/add/modify partitions to identify best fit for data access to data.
  • Confirm that you have sufficient space available to ensure reorg success with multiple automatic space-check audits.

Oracle's partitioning option

Required for the Online Switch (a feature available for live reorganizations) and the Partitioning Wizard; Partitioning Option must be installed and licensed.

XDB schema

Requirements for the Capacity Manager Repository

The database used for the Capacity Manager repository must meet the following requirements:

Oracle database

Supported for the repository:

  • Oracle 9.2
  • Oracle 10.2
