╔══════════════════════════════════════════════════════════════════════════════════ ║ ║ ║ NitroWebExpress™ ORCHESTRATION SYSTEM ║ ║ ║ ║ Master Control Scripts & Standardized Module Scripts ║ ║ ║ ║ Completed: July 3, 2026 ║ ║ ║ ╚══════════════════════════════════════════════════════════════════════════════════
═══════════════════════════════════════════════════════════════════════════════════ OVERVIEW ═══════════════════════════════════════════════════════════════════════════════════
This document describes the complete system orchestration infrastructure for NitroWebExpress™. All startup/shutdown operations can now be performed from the master /scripts folder, with:
✓ Centralized control of MySQL, backends, and frontends ✓ Clean, consistent output formatting across all scripts ✓ Cross-references between master and module scripts ✓ Idempotent operations (safe to run multiple times) ✓ Comprehensive system status reporting
═══════════════════════════════════════════════════════════════════════════════════ MASTER CONTROL SCRIPTS (in /scripts) ═══════════════════════════════════════════════════════════════════════════════════
These scripts provide centralized control of the entire system:
┌────────────────────────────────────────────────────────────────────────────────── │ start-all.sh ├────────────────────────────────────────────────────────────────────────────────── │ ORCHESTRATES COMPLETE SYSTEM STARTUP │ │ Usage: bash scripts/start-all.sh [tomcat_home] │ │ Sequence: │ 1.

═══════════════════════════════════════════════════════════════════════════════════ MODULE SCRIPTS (in /modules//[start|shutdown].) ═══════════════════════════════════════════════════════════════════════════════════
Each module now has standardized scripts with consistent formatting:
FRONTEND SCRIPTS (all 12 modules):
start.sh Deploys module to Tomcat, starts Tomcat if needed shutdown.sh Undeploys module from Tomcat, optionally stops Tomcat
BACKEND SCRIPTS (10 modules + Futures):
start-backend.sh Starts TCP backend server, stores PID shutdown-backend.sh Stops TCP backend server gracefully
SPECIAL CONVENTION (Futures module):
start-frontend.sh (instead of start.sh) start-backend.sh (standard naming) shutdown-frontend.sh (instead of shutdown.sh) shutdown-backend.sh (standard naming)

═══════════════════════════════════════════════════════════════════════════════════ QUICK START GUIDE ═══════════════════════════════════════════════════════════════════════════════════
COMPLETE SYSTEM STARTUP:
$ cd /home/mearvk/IdeaProjects/Java.Web.Server.Telnet.Front.Java.21 $ bash scripts/start-all.sh
(or with explicit Tomcat path) $ bash scripts/start-all.sh /opt/tomcat
This will: 1. Start MySQL 2. Start all backend TCP servers 3. Deploy all modules to Tomcat 4. Display startup summary
COMPLETE SYSTEM SHUTDOWN:
$ bash scripts/shutdown-all.sh
(or with explicit Tomcat path) $ bash scripts/shutdown-all.sh /opt/tomcat --stop-tomcat
This will: 1. Undeploy all modules from Tomcat 2. Stop Tomcat (if --stop-tomcat specified) 3. Stop all backend servers 4. Stop MySQL 5. Display shutdown summary
SYSTEM STATUS CHECK:
$ bash scripts/status.sh
This will display: - MySQL running/stopped status - All backend services status (PID, running/stopped) - All frontend services status (HTTP codes) - Overall summary
INDIVIDUAL MODULE CONTROL:
Start single backend: $ cd modules/AE6E66 $ bash start-backend.sh
Start single frontend: $ cd modules/AE6E66 $ bash start.sh
Stop single module: $ cd modules/AE6E66 $ bash shutdown.sh $ bash shutdown-backend.sh
PARTIAL STARTUP:
Just start MySQL: $ bash scripts/start-mysql.sh
Just start backends: $ bash scripts/start-backends.sh
Just start frontends: $ bash scripts/start-frontends.sh
═══════════════════════════════════════════════════════════════════════════════════ OUTPUT FORMATTING ═══════════════════════════════════════════════════════════════════════════════════
All scripts now use CONSISTENT, BEAUTIFUL output with:
✓ Unicode box drawing (╔═╚╝║) ✓ Indented status indicators: [*] = operation in progress [✓] = success [--] = skipped [!] = warning [FAIL] = failure ✓ Cross-references to related scripts ✓ Progress indicators for multi-step operations ✓ PID and status information clearly displayed ✓ Hyperlinks to logs and management commands
EXAMPLE OUTPUT:
╔═══════════════════════════════════════════════════════════════════════════╗ ║ AE6E66 Backend Server — Startup ║ ║ JVM: -Xms64m -Xmx256m ║ ╚═══════════════════════════════════════════════════════════════════════════╝

═══════════════════════════════════════════════════════════════════════════════════ TROUBLESHOOTING ═══════════════════════════════════════════════════════════════════════════════════
Problem: start-all.sh fails immediately Solution: Check Tomcat path with: bash scripts/start-all.sh /path/to/tomcat
Problem: MySQL not starting Solution: Check logs with: bash scripts/detect-mysql.sh Or manually: sudo systemctl start mysql
Problem: Backend servers not starting Solution: Check individual module logs: tail -f modules/AE6E66/logging/backend.log
Problem: Frontends not deploying Solution: Check Tomcat logs: tail -f /opt/tomcat/logs/catalina.out
Problem: status.sh shows failures Solution: Run individual modules to diagnose: cd modules/AE6E66 && bash start-backend.sh
Problem: Port already in use Solution: Find process: lsof -i :9999 Or check all backends: ps aux | grep java
═══════════════════════════════════════════════════════════════════════════════════ PERFORMANCE CHARACTERISTICS ═══════════════════════════════════════════════════════════════════════════════════
Startup Time (approximate): MySQL: 2-5 seconds Backends (10): 3-5 seconds total (mostly parallel) Frontends (12): 5-10 seconds (sequential deployment) Health checks: 5-15 seconds (polling) ──────────────────────────── TOTAL: 15-35 seconds for complete startup
Shutdown Time (approximate): Frontends (12): 2-5 seconds (sequential undeployment) Backends (10): 2-3 seconds (kill signals) MySQL: 2-3 seconds (graceful shutdown) ──────────────────────────── TOTAL: 6-11 seconds for complete shutdown
Resource Usage: Startup scripts: negligible (bash, curl, grep) Running system: depends on application load Logging: all output to modules/*/logging/
═══════════════════════════════════════════════════════════════════════════════════ MAINTENANCE NOTES ═══════════════════════════════════════════════════════════════════════════════════
Adding a new module:
- Create module structure in modules/NEW_MODULE/
- Generate scripts using: python3 /tmp/generate_module_scripts.py
- Update /scripts/start-backends.sh (add to MODULES dict)
- Update /scripts/start-frontends.sh (add to MODULES list)
- Update /scripts/status.sh (add to BACKENDS and CONTEXTS)
- Test: bash /scripts/start-all.sh
Adding a new context path:
- Update module's deploy-local.sh
- Update corresponding start.sh (CONTEXT variable)
- Update /scripts/start-frontends.sh and shutdown-frontends.sh
- Update /scripts/status.sh (add to CONTEXTS)
Modifying output format:
- Edit template in /tmp/standardize_module_scripts.py
- Re-run to regenerate all module scripts
- Test manually to verify changes
