Case Study: Blitz Report Parameter Comparison between environments
Executive Summary
The Blitz Report Parameter Comparison between environments report is a specialized diagnostic tool designed for Oracle E-Business Suite administrators and developers. It facilitates the comparison of Blitz Report parameters between the local database instance and a remote environment. This tool is crucial for maintaining configuration consistency across Development, Test, and Production environments, ensuring that report definitions remain synchronized and functional throughout the release lifecycle.
Business Challenge
In a multi-environment Oracle EBS landscape, keeping report definitions aligned is a significant challenge. As reports are developed and promoted, parameter definitions—including default values, lists of values (LOVs), and validation logic—can drift.
- Configuration Drift: Discrepancies between environments can lead to reports failing or producing incorrect data after migration.
- Manual Validation: Manually checking hundreds of parameters across environments is time-consuming and prone to human error.
- Troubleshooting: Identifying why a report works in “Test” but fails in “Production” often requires a detailed comparison of the underlying parameter setups.
Solution
This report automates the validation process by querying and comparing parameter metadata from the local environment against a target remote database.
- Automated Comparison: Instantly identifies differences in parameter attributes such as SQL text, default values, and LOV definitions.
- Targeted Analysis: Users can filter comparisons by Report Category or specific Report Names to focus on relevant changes.
- Exception Reporting: The “Show Differences only” parameter allows users to filter out matching records, highlighting only the discrepancies that require attention.
Technical Architecture
The report operates by querying the xxen_report_parameters_v view locally and comparing it with data from a remote database.
Remote View Requirement
To successfully run this comparison and avoid the ORA-64202: remote temporary or abstract LOB locator is encountered error, a specific view must be created on the remote environment. This view handles CLOB data types (like SQL text) by converting them to a format suitable for remote querying.
Required Remote View Definition:
create or replace view xxen_report_parameters_v_ as
select
xrpv.*,
dbms_lob.substr(xxen_util.clob_substrb(xrpv.sql_text,4000,1)) sql_text_short,
dbms_lob.substr(xxen_util.clob_substrb(xrpv.lov_query,4000,1)) lov_query_short,
length(xrpv.sql_text) sql_length,
count(*) over (partition by xrpv.report_id) parameter_count
from
xxen_report_parameters_v xrpv;
Key Views and Tables
xxen_report_parameters_v: The primary source of parameter definitions in the local environment.xxen_report_parameters_v_: The custom view required on the remote environment to facilitate LOB handling over a database link.fnd_user: Used to identify user-specific configurations or updates.
Parameters
The report accepts the following parameters to refine the comparison scope:
- Remote Database: Specifies the target environment for comparison (typically a database link).
- Category: Filters the comparison to a specific group of reports (e.g., “Enginatics”, “Finance”).
- Report Name like: Allows wildcard searching for specific report titles.
- Show Differences only: A boolean flag to suppress matching rows and display only parameters with discrepancies.
Performance
Performance is largely dependent on the network latency between the local and remote databases. The use of the optimized xxen_report_parameters_v_ view ensures that LOB data is handled efficiently, preventing common errors associated with querying CLOBs over database links.
FAQ
Q: Why do I get an ORA-64202 error?
A: This error occurs if the remote environment does not have the xxen_report_parameters_v_ view installed. This view is necessary to handle LOB locators correctly across the network.
Q: Can I compare standard Oracle Concurrent Program parameters with this tool? A: No, this tool is specifically designed for Blitz Report parameters.
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.
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.
