Overview

The HXC_LOCKER_TYPES table is a core data object within the Oracle E-Business Suite (EBS) Time and Labor Engine (HXC). It serves as the master repository for defining different locker types, which are fundamental components of the system's locking mechanism. In the context of Time and Labor, locking is a critical process that prevents conflicting updates to timecard data, ensuring data integrity during approval workflows and batch processing. This table stores the definitions of these lock types, which are subsequently referenced by locking rules and active locks to control and track access to timecard records.

Key Information Stored

While the provided metadata does not list specific columns, the primary and foreign key relationships define its critical structure. The central column is LOCKER_TYPE_ID, which serves as the unique primary key identifier for each locker type definition. The table's description indicates it holds "locker type components," which typically includes attributes defining the lock's behavior and purpose. Based on standard EBS patterns and the related objects, this table likely stores descriptive information such as a name, code, and potentially a classification or category for the locker type. The LOCKER_TYPE_ID is the essential foreign key referenced by other locking entities in the system.

Common Use Cases and Queries

This table is primarily used for setup, diagnostic, and reporting purposes related to the Time and Labor locking framework. Common scenarios include identifying all configured locker types within the system or troubleshooting locking conflicts by tracing a lock back to its type definition. A typical query would join HXC_LOCKER_TYPES with the HXC_LOCKS table to analyze currently held locks. For example, a report to show active locks and their types might use SQL similar to:

  • SELECT lt.locker_type_id, lt.name, l.resource_id, l.resource_type FROM hxc_locker_types lt, hxc_locks l WHERE lt.locker_type_id = l.locker_type_id AND l.lock_status = 'ACTIVE';

Another critical use case is validating the setup of locking rules in HXC_LOCKING_RULES, which reference locker types for both the owner and requestor entities involved in a locking rule definition.

Related Objects

The HXC_LOCKER_TYPES table has integral relationships with several other key Time and Labor tables, as defined by its foreign keys:

  • HXC_LOCKING_RULES: This table references HXC_LOCKER_TYPES twice. The LOCKER_TYPE_OWNER_ID column identifies the locker type for the entity that owns or holds the lock, while the LOCKER_TYPE_REQUESTOR_ID identifies the locker type for the entity requesting the lock. This defines the locking interaction between different process participants.
  • HXC_LOCKS: This table tracks all active (and potentially historical) locks in the system. Its LOCKER_TYPE_ID column links each specific lock instance to its type definition stored in HXC_LOCKER_TYPES, providing context for the lock's purpose.

Together, these objects form the backbone of the concurrency control system within Oracle Time and Labor, with HXC_LOCKER_TYPES acting as the definitional source.
