R Code Database Management Scripts Overview Including Data Visualization
The table below provides a comprehensive summary of 12 specialized R scripts designed for Oracle database administration, performance monitoring, security analysis, and capacity planning. These automated tools connect to Oracle databases via ODBC, analyze historical and real-time data, and generate structured reports (PDF/HTML) with visualizations and actionable insights. They are organized into logical categories based on their primary functions—performance monitoring, security and auditing, capacity and growth analysis, session and process management, and backup/export operations. Each script serves a distinct purpose, from detecting suspicious login patterns and predicting database growth to optimizing export processes with parallel processing. Together, they form a robust toolkit for proactive database management, risk mitigation, and operational efficiency.
Script Name
Description
Purpose
Category
1-DB_Performance.r
Analyzes Oracle database performance metrics (CPU, memory, wait events) using statistical modeling and generates PDF reports.
To monitor system performance, identify bottlenecks, and predict issues using Random Forest models.
Performance Monitoring
2-DB_Backup_Failure.r
Analyzes backup success/failure patterns, builds predictive models (XGBoost), and generates reports with recommendations.
To improve backup reliability by identifying failure patterns and optimizing backup schedules.
Backup & Recovery
3-DB_Tablespace_Growth_PDF-Report.r
Monitors tablespace usage, forecasts capacity issues, and generates PDF reports with ARIMA forecasting.
To predict tablespace exhaustion and plan capacity expansion proactively.
Capacity & Growth Analysis
4-DB_Sizing_Report.r
Analyzes database growth patterns, calculates sizing trends, and generates PDF reports with daily growth visualizations.
To track database size changes over time and support storage planning.
Capacity & Growth Analysis
5-DB_Growth_Prediction.r
Extends sizing analysis with time-series forecasting (ARIMA) to predict future database growth.
To forecast database growth for the next 30 days based on historical trends.
Capacity & Growth Analysis
6-DB_Session_Longevity.r
Performs survival analysis on database sessions, identifies long-running sessions, and generates PDF reports.
To analyze session patterns, detect abnormal session durations, and optimize connection management.
Session & Process Management
7_1-Predict_All_export_timing.r
Estimates export times for all schemas using 16 parallel processes, generates PDF reports, and provides Data Pump command templates.
To optimize full database export operations with parallel processing and provide accurate time estimates.
Export & Migration
7_2-Predict_Full_export_timing.r
Analyzes full database exports with 16 parallel processes, estimates timing, and generates detailed HTML reports.
To plan and execute full database exports efficiently using parallel Data Pump.
Export & Migration
8-Long_Running_Queries.r
Identifies and analyzes long-running queries, generates visualizations, and creates PDF reports for performance monitoring.
To pinpoint resource-intensive queries and provide insights for query optimization.
Performance Monitoring
9-Detect_Suspicious_Login.r
Analyzes login activity to detect security breaches via IP patterns, client programs, and non-business hour access.
To identify unauthorized access attempts and compromised accounts through anomaly detection.
Security & Auditing
10-DB_Security_Risks.r
Performs advanced security risk analysis using anomaly detection, behavioral clustering, and pattern analysis.
To proactively monitor user activities, detect malicious behavior, and assess security vulnerabilities.
Security & Auditing
11-Process_Monitoring_Analysis.r
Monitors database processes, detects anomalies using statistical and time-series methods, and generates comprehensive reports.
To ensure system stability by identifying abnormal process behavior and resource contention.
