Case Study & Technical Analysis

Abstract

The DBA Tablespace Usage report is the primary instrument for storage capacity planning and monitoring. It provides a unified view of space utilization across all types of tablespaces: Permanent (Data/Index), Temporary (Sort/Hash), and Undo (Rollback). By calculating the “Used” vs. “Allocated” vs. “Max Size” (autoextend), it gives a true picture of remaining capacity.

Technical Analysis

Core Logic

Permanent Tablespaces: usage is calculated based on extent allocation in DBA_DATA_FILES.
Temp Tablespaces: Usage is dynamic, based on V$SORT_SEGMENT or DBA_TEMP_FILES.
Undo Tablespaces: Usage is based on active vs. expired extents in DBA_UNDO_EXTENTS.

Key Views

DBA_TABLESPACE_USAGE_METRICS: A convenient view that pre-calculates usage percentages, accounting for auto-extensibility.
DBA_DATA_FILES / DBA_TEMP_FILES: Physical file definitions.

Operational Use Cases

Alerting: “Alert me when the APPS_TS_TX_DATA tablespace is 90% full.”
Cleanup: Identifying tablespaces that are unexpectedly filling up due to unpurged interface tables.
Undo Sizing: Monitoring if the Undo tablespace is large enough to support the UNDO_RETENTION period without “Snapshot too old” errors.

Oracle E-Business Suite Reporting Library

We provide an open source Oracle EBS SQLs as a part of operational and project implementation support toolkits for rapid Excel reports generation.

Blitz Report™ is based on Oracle EBS forms technology, and hence requires minimal training. There are no data or performance limitations since the output files are created directly from the database without going through intermediate file formats such as XML.

Blitz Report can be used as BI Publisher and Oracle Discoverer replacement tool. Standard Oracle BI Publisher and Discoverer reports can also be imported into Blitz Report for immediate output to Excel. Typically, reports can be created and version tracked within hours instead of days. The concurrent request output automatically opens upon completion without the need for re-formatting.

The Filters, Columns, Rows and Values fields are used to create and deliver the data in pivot table format with full drill down to details.

Blitz Report Pivots

The Excel template upload functionality in Blitz Report allows users to create their own layouts by uploading an Excel template with additional sheets and charts, automatically refreshed when the report runs again. This allows to create custom dashboards and more advanced visualizations of report data.

Blitz Report Dashboard

You can download and use Blitz Report free of charge for your first 30 reports.

The installation and implementation process usually takes less than 1 hour; you can refer to our installation and user guides for specific details.

If you would like to optimize your Oracle EBS implementation and or operational reporting you can visit www.enginatics.com to review great ideas and example usage in blog. Or why not try for yourself in our demo environment.
