Troubleshooting Common Issues in Oracle BI Publisher Desktop

Migrating Reports to Oracle BI Publisher: Best Practices

1. Plan and inventory

• Audit reports: catalog all reports, owners, schedules, run frequency, and last-run date.
• Prioritize: migrate high-value, high-use, regulatory, and scheduled reports first; archive unused reports.

2. Define target architecture

• Repository choice: file system vs XML DB (WebDAV/FTP).
• Execution environment: on-prem vs cloud, BI Publisher Server version compatibility, required Java/JDBC libs.
• Data sources: list databases, PL/SQL packages, web services, and any non‑JDBC sources.

3. Choose conversion approach

• Automated conversion: use Oracle’s Report Conversion Assistant for Oracle Reports → BI Publisher to generate data model PL/SQL, report definition, and RTF templates. Good for bulk conversions but expect manual fixes.
• Manual rebuild: recommended for complex layouts, dynamic formatting, or when conversion output is poor. Recreate data model and design with BI Publisher Desktop (Word add-in).

4. Prepare source reports and environment

• Export to supported format: ensure Oracle Reports are saved as RDF XML if required.
• Install tools: BI Publisher Server, BI Publisher Desktop (Office add-in), and conversion utilities; ensure required JARs (xmlparserv2, xdo-core, aolj, etc.) are in classpath.
• Database objects: plan PL/SQL package generation/upload steps for converted data models.

5. Convert and migrate

• Run conversion in batches: convert grouped by complexity or application module.
• Upload converted assets: copy folders to the BI Publisher repository (or upload via WebDAV/XML DB) and refresh metadata.
• Version control: store templates, data models, and SQL/PLSQL scripts in source control.

6. Test thoroughly

• Data validation: compare outputs (row counts, totals, key fields) between source and converted reports.
• Layout validation: verify pixel-perfect formatting for financial/legal docs.
• Performance testing: benchmark query and report run-times; optimize SQL or add indexes as needed.
• Regression testing: run scheduled bursts and delivery channels (email, FTP) to confirm behavior.

7. Fix common conversion issues

• Recreate complex layouts in Word using BI Publisher Desktop when conversion tool fails.
• Replace Report-specific functions with PL/SQL or XSL/BI Publisher functions.
• Move embedded logic from layout into data model PL/SQL for maintainability.

8. Cutover and coexistence

• Phased cutover: run old and new reports in parallel for a validation window.
• Stakeholder sign-off: get business approval on outputs before retiring legacy reports.
• Communication & training: train report authors and consumers on BI Publisher templates, scheduling, and troubleshooting.

9. Post-migration tasks

• Clean up: decommission legacy report repository and remove obsolete scheduled jobs.
• Monitoring: add alerts for failed jobs, long-running reports, and repository errors.
• Governance: establish naming, folder, and ownership conventions; enforce template/version control.

10. Tips to reduce effort and risk

• Prune first: reduce report count before converting.
• Convert simple reports first to build momentum and refine conversion steps.
• Keep templates modular: use reusable templates/snippets for common headers/footers.
• Engage SMEs early: involve DBAs for SQL tuning and app owners for business validation.
• Document exceptions: record reports needing heavy manual work and budget accordingly.
