Case Study & Technical Analysis
Abstract
The DBA Scheduler Jobs report provides a comprehensive inventory of automated tasks managed by the Oracle Scheduler (DBMS_SCHEDULER). As the modern replacement for the legacy DBMS_JOB interface, the Scheduler offers advanced features like chains, windows, and resource manager integration. This report is essential for auditing background processes, verifying job schedules, and troubleshooting execution failures in the Oracle E-Business Suite and database infrastructure.
Technical Analysis
Core Features
- Job Inventory: Lists all defined scheduler jobs, their owners, and enabled status.
- Schedule Details: Displays the
REPEAT_INTERVAL(e.g., “freq=daily;byhour=2”), next run time, and last run duration. - Execution History: While primarily a configuration report, it often correlates with run logs to show failure counts and last run status.
Comparison: DBMS_SCHEDULER vs. DBMS_JOB
- DBMS_JOB: Legacy, simple interval-based execution.
- DBMS_SCHEDULER: Modern, calendar-syntax based, supports dependency chains, external scripts, and integration with Oracle Resource Manager.
Key View
DBA_SCHEDULER_JOBS: The central catalog view for all scheduler job definitions and their current runtime status.
Operational Use Cases
- System Audit: Verifying that critical maintenance jobs (stats gathering, backups, purging) are enabled and scheduled correctly.
- Troubleshooting: Identifying jobs that are broken, disabled, or failing repeatedly.
- Performance Management: Ensuring resource-intensive jobs are scheduled during maintenance windows to avoid impacting online users.
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.

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.

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.
