Case Study & Technical Analysis

Abstract

The DBA SGA Memory Allocation report provides a high-level summary of the System Global Area (SGA) configuration. It displays the current size of major memory components such as the Buffer Cache, Shared Pool, Large Pool, and Java Pool. This report is essential for verifying memory settings, especially when using Automatic Shared Memory Management (ASMM) or Automatic Memory Management (AMM).

Technical Analysis

Core Components

Buffer Cache: Memory for caching data blocks.
Shared Pool: Memory for the library cache (SQL plans), dictionary cache, and PL/SQL code.
Large Pool: Used for RMAN backups, parallel query message buffers, and UGA (in shared server mode).
Java Pool: Memory for the JVM within the database.
Log Buffer: Memory for redo entries.

Key View

GV$SGAINFO: Provides accurate, dynamic sizing information for SGA components, reflecting the current state after any automatic resizing operations.

Operational Use Cases

Configuration Audit: Verifying that the SGA_TARGET or SGA_MAX_SIZE parameters are being respected.
Tuning ASMM: Checking if Oracle is “stealing” memory from the Buffer Cache to feed a growing Shared Pool (a common symptom of literal SQL flooding).
OOM Troubleshooting: Investigating ORA-04031 (unable to allocate bytes of shared memory) errors by seeing which component is consuming the space.

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.
