Mastering Database Health with 4i’s Oracle APEX-Powered Solution
At 4i, we believe that managing database health shouldn’t be a guessing game or a manual chore. Our custom-built Oracle Database Health Check application, developed using Oracle APEX, is designed to give DBAs and system administrators real-time visibility into their database and application environments—quickly, securely, and effectively.
Use Case: Proactive System Monitoring with 4i
Imagine you’re a DBA juggling multiple critical projects. Each has its own Oracle database and application stack. You need instant insights—whether it’s memory pressure, a failed backup, or a backlog of concurrent requests—without digging through logs or writing ad-hoc queries. That’s where 4i’s Health Check application steps in.
Features and Functionality
Secure Login Page
The login page offers more than just access—it introduces users to the purpose of 4i’s Health Check app: ensuring continuous system health visibility across all Oracle assets. Users log in securely, maintaining access control and data protection.

Database Monitoring Dashboard
This dashboard delivers a unified view of key metrics with interactive visualizations and real-time updates.
- Disk Information: Visual breakdown of disk usage with stats on file system, available/used space, total size, and mount points.
- CPU Usage: Deep insights into CPU activity including utilization per core, system/user usage, nice value, and idle time.
- Memory Usage: A donut chart shows memory distribution—free, used, and total—at a glance for immediate performance decisions.
- System Status: Includes listener state, database availability, database size (AFP), and active sessions count.
- Data Guard Status: Keep an eye on database replication integrity—track sequence activity and failover readiness.
- RMAN Backup Monitoring: Know your backup health with details on type, device, compression, throughput, and duration.
- Tablespace Utilization: Easily monitor storage consumption and plan proactively with usage percentages per tablespace.
Application Monitoring Dashboard
In true 4i fashion, we don’t stop at databases—our monitoring app goes deeper into application workflows:
- Workflow Status: Track the status and startup mode of all key workflow components to detect issues fast.
- Pending Requests: Breaks down queued requests by user, concurrent queue, processes, and standby/running states for better resource management.

Intelligent File Upload & Automated Processing
4i’s Health Check app integrates both manual and automated mechanisms to ingest and analyze HTML-based reports.
Manual Uploads
Users can upload HTML reports via the UI. The system identifies the file type (application or database) and processes accordingly.
Email-Based Automation
Reports emailed into the system are automatically ingested into a common holding table, ready for extraction and storage.
Scheduled Data Refresh
Every 10 minutes, the system scans for new files, extracts key data, and inserts it into the correct destination table—keeping your dashboards fresh and relevant.
Behind the Scenes: Our Engine
- Database File Processor: Parses and stores metrics like CPU, listener status, and memory usage.
- Application File Processor: Extracts workflow statuses and request logs for seamless analysis.
Automation = Efficiency
With 4i’s automation engine:
- Manual effort is reduced
- Updates are timely
- Data is accurate
