Executive Summary

The GCC engagement was a SQL-intensive Oracle EBS diagnostic and remediation engagement, evidenced by dedicated SQL, Scripts, and Questionnaire subfolders alongside standard Oracle documentation. This pattern — questionnaires to gather information about the Oracle environment, SQL scripts to diagnose issues, and remediation scripts to resolve them — is characteristic of a structured Oracle health check and support engagement rather than a greenfield implementation.

The breadth of the module scope (PO, GL, FA, INV) across a 16-subfolder project structure indicates a comprehensive Oracle environment review covering both financial and supply chain modules — likely addressing a range of accumulated issues across an Oracle instance that had been operating without systematic maintenance.

Engagement Context

Oracle EBS environments operating for several years without regular health checks accumulate issues that individually may seem minor but collectively degrade system performance, data integrity, and operational efficiency. The GCC engagement's questionnaire-based approach reflects a structured assessment methodology: gather environmental information through structured questions, use SQL queries to validate the environment against expected configurations, identify deviations and issues, and apply targeted script-based remediations.

This approach — assess first, remediate second — is more systematic than reactive support engagements that address individual reported issues without understanding the broader environment context. The questionnaire and SQL artifacts produced in this engagement represent reusable Oracle health check tools applicable to any Oracle EBS environment of similar scope.

Oracle Diagnostic Scope

Questionnaire-Based Assessment

Structured questionnaires were used to gather information about the Oracle environment that cannot be determined from database queries alone: business process changes since implementation, known issues that users have worked around, configuration changes made outside formal change control, and areas where Oracle behavior does not match user expectations. Questionnaire responses directed the subsequent SQL diagnostic focus.

SQL Diagnostic Scripts

SQL diagnostic scripts queried Oracle's standard tables and views to identify: configuration deviations from Oracle best practice, data integrity issues (orphaned records, missing required values, incorrectly coded transactions), performance bottlenecks, and subledger-to-GL reconciliation discrepancies. Scripts were organized by module (PO, GL, FA, INV) for systematic execution and result analysis.

Remediation Scripts

Where diagnostic scripts identified correctable issues, remediation scripts were developed to address them — either through Oracle's standard data correction APIs or through targeted UPDATE/INSERT statements with appropriate Oracle support guidance. All remediation scripts were tested in a non-production environment before production application.

Consultant Insights

On SQL-Based Oracle Diagnostics: The most efficient Oracle EBS diagnostic approach combines structured questionnaires (to understand what users experience) with SQL queries against Oracle's own tables (to understand what the system actually contains). User reports and system data frequently disagree — the discrepancy between what users say and what the database shows is often where the root cause lives. Never diagnose an Oracle issue from user reports alone; always query the data.

On Reusable Diagnostic Scripts: A well-built SQL diagnostic script library — organized by module and covering common Oracle EBS health check areas — is one of the highest-value reusable assets in an Oracle consulting practice. The scripts developed for GCC (and refined across similar engagements) represent institutional knowledge that dramatically accelerates future diagnostic engagements. Maintain a version-controlled diagnostic script library as a practice asset.

On Questionnaire Design: Diagnostic questionnaires are most useful when they ask about behaviors and outcomes ("invoices that should have been paid are still on hold") rather than system configuration ("is three-way matching enabled?"). Business users know what isn't working; they don't know the Oracle configuration that's causing it. Design questions to capture business symptoms; use SQL to translate those symptoms into root causes.
