Overview

The FND_RANDOM_STATES table is a core Application Object Library (FND) table within Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2. Its primary role is to support the secure pseudo-random number generation (PRNG) infrastructure of the application. This functionality is critical for generating cryptographically secure values used in various security-sensitive operations, such as creating non-predictable session identifiers or encryption keys. The table acts as a persistent store for the internal state of the random number generator, ensuring the sequence's continuity and security across sessions and processes. According to the provided ETRM documentation, it is explicitly noted as "Not implemented in this database," indicating that while the table is defined in the application's data model, it may not be populated or actively used in a standard installation, potentially reserved for specific advanced security configurations.

Key Information Stored

The table's structure is minimal, centered on a single primary key column that maintains the generator's state. Based on the documented relationship data, the sole and critical column is LOCK_ID. This column serves as the primary key for the table (FND_RANDOM_STATES_PK) and stores the unique identifier or token representing the current state of the pseudo-random number generator. The state information is essential for the PRNG algorithm to produce the next value in its sequence while maintaining the required properties of randomness and security. No other columns are detailed in the provided metadata, underscoring the table's specialized, single-purpose design.

Common Use Cases and Queries

Direct interaction with this table by developers or administrators is exceptionally rare. Its management is handled internally by the Application Object Library's security and utility APIs. The primary use case is the behind-the-scenes generation of secure random numbers when called by other EBS functions. Given its "Not implemented" status and sensitive nature, there are no standard reporting use cases. Should investigation be necessary, a query would be simple due to the minimal structure. A sample SQL to check for the existence of any state information would be: SELECT lock_id FROM fnd_random_states;. In a typical environment, this query is expected to return no rows. Any manipulation of data in this table would be performed exclusively by Oracle-provided APIs, not via direct DML.

Related Objects

The relationships for FND_RANDOM_STATES are defined solely by its primary key constraint. As per the provided ETRM relationship data:

  • Primary Key Constraint: FND_RANDOM_STATES_PK on column LOCK_ID.
The metadata does not list any foreign key constraints referencing this table from other objects. This absence of inbound relationships suggests that the table is a standalone repository for the PRNG state. Access is mediated through proprietary Application Object Library packages, likely such as FND_CRYPTO or similar security utilities, which are not enumerated in the provided excerpt. The table's isolation is intentional to protect the integrity of the random number generation process.
