The FND_EXCLUDE_TABLE_STATS table in Oracle E-Business Suite (EBS) 12.1.1 and 12.2.2 serves a critical function in managing database statistics collection for tables that should be excluded from automated statistics gathering processes. This table is part of Oracle Applications' foundational technology layer, specifically within the Oracle Application Object Library (FND) schema. Its primary purpose is to prevent the Oracle Optimizer from generating suboptimal execution plans by excluding certain tables from statistics collection, particularly when those tables have volatile data, are temporary, or contain data that does not benefit from statistics-based optimization.

In Oracle EBS environments, maintaining accurate database statistics is essential for query performance. However, certain tables—such as temporary tables, logging tables, or tables with highly transient data—can negatively impact performance if statistics are collected on them. The FND_EXCLUDE_TABLE_STATS table provides a centralized mechanism to identify such tables, ensuring they are skipped during statistics gathering jobs like those executed by the FND_STATS or DBMS_STATS utilities. This exclusion helps avoid unnecessary overhead and potential performance degradation caused by frequent statistics recomputation on irrelevant or volatile data.

The structure of the FND_EXCLUDE_TABLE_STATS table typically includes columns such as TABLE_NAME, SCHEMA_NAME, and EXCLUDED_FLAG, which together define the tables to be excluded. For example, a table marked with EXCLUDED_FLAG='Y' will be bypassed during statistics collection. Administrators can manually populate this table or use Oracle-provided scripts to automate exclusions based on predefined criteria. Additionally, the table may integrate with Oracle's Auto Optimizer Statistics Collection feature, ensuring compatibility with broader database maintenance strategies.

In EBS 12.1.1 and 12.2.2, the FND_EXCLUDE_TABLE_STATS table is particularly relevant in multi-organization (Multi-Org) and multi-language environments, where certain shared tables may not require statistics for all instances. By leveraging this table, administrators can fine-tune statistics collection to align with business requirements, reducing maintenance windows and improving system responsiveness. Proper configuration of this table is crucial, as incorrect exclusions can lead to performance issues, while missing exclusions may result in unnecessary resource consumption.

To summarize, the FND_EXCLUDE_TABLE_STATS table is a strategic component in Oracle EBS for optimizing statistics management. It ensures that database performance tuning efforts are focused on relevant data, avoiding inefficiencies caused by volatile or temporary tables. Administrators should regularly review and update this table to reflect changing data patterns, ensuring optimal performance in dynamic EBS environments.
