In day-to-day Oracle Database and E-Business Suite (EBS) administration, proactive monitoring is critical to ensure system stability, performance, and availability.
As part of my real-world DBA experience, I created a set of health check scripts to quickly assess the status of key database components.
🎯 Objective
The goal of this script is to provide a quick and efficient health check for:
- Database status
- Instance status
- Tablespace usage
- Invalid objects
- RMAN backup status
🛠️ Solution Overview
I developed a SQL-based script (hc.sql) that gathers essential health metrics from Oracle dynamic views and DBA tables.
These scripts are designed to:
- Be lightweight and fast
- Provide immediate insights
- Help DBAs take proactive action
📂 GitHub Repository
You can access the complete script here:
👉 https://github.com/Syedanwarahmed/scripts_for_healthcheck
📌 Key Features
- ✅ Database and instance status check
- ✅ Tablespace usage monitoring
- ✅ Active session tracking
- ✅ Invalid object detection
- ✅ RMAN backup job verification
- ✅ Easy execution using SQL*Plus
⚙️ How to Use
Run the script using SQL*Plus:
sqlplus / as sysdba
@hc.sql
🔍 Sample Checks Included
✔️ Database Status
SELECT NAME, OPEN_MODE, DATABASE_ROLE FROM V$DATABASE;
✔️ Tablespace Usage
SELECT TABLESPACE_NAME, BYTES FROM DBA_DATA_FILES;
✔️ Active Sessions
SELECT COUNT(*) FROM V$SESSION WHERE STATUS='ACTIVE';
✔️ RMAN Backup Status
SELECT STATUS, START_TIME FROM V$RMAN_BACKUP_JOB_DETAILS;
💡 Real-World Value
These scripts are derived from real-time production support scenarios where quick diagnosis is required during:
- High CPU issues
- Backup failures
- Tablespace alerts
- Performance degradation
Having a single script to validate system health saves valuable time during critical situations.
🚀 Future Enhancements
I plan to enhance this repository further by adding:
- Shell automation scripts
- Alerting mechanisms
- Integration with monitoring tools
- Additional EBS-specific checks

🔚 Conclusion
A well-designed health check script is an essential tool for every DBA. It not only helps in proactive monitoring but also ensures faster troubleshooting and improved system reliability.
If you are working with Oracle databases, I highly recommend building or using such scripts as part of your daily operations.
