Recommended Actions

Option 1: Check Database Server Status

On the database server (192.168.11.105):

# Check PostgreSQL service status
sudo systemctl status postgresql

# Start PostgreSQL if stopped
sudo systemctl start postgresql

# Enable PostgreSQL to start on boot
sudo systemctl enable postgresql

# Check if PostgreSQL is listening on port 5432
sudo netstat -tlnp | grep 5432
# or
sudo ss -tlnp | grep 5432

Option 2: Check Network Connectivity

From this machine:

# Ping the database server
ping -c 3 192.168.11.105

# Test port connectivity
nc -zv -w 2 192.168.11.105 5432

# Test with telnet
telnet 192.168.11.105 5432

Option 3: Use Docker Compose (Development)

If database is not available, use Docker Compose:

cd dbis_core
docker-compose -f docker/docker-compose.as4.yml up -d postgres redis

# Update .env with:
# DATABASE_URL=postgresql://dbis_user:dbis_password@localhost:5432/dbis_core

Option 4: Verify Database Configuration

Check database configuration:

# Verify .env file
cat dbis_core/.env | grep DATABASE_URL

# Test connection manually
psql postgresql://dbis:***@192.168.11.105:5432/dbis_core -c "SELECT version();"

When Database is Available

Step 1: Run Migration

cd dbis_core
npx prisma migrate deploy

Step 2: Seed Marketplace

npx ts-node scripts/seed-as4-settlement-marketplace-offering.ts

Step 3: Verify Database Status

./scripts/check-database-status.sh

Step 4: Start Server

npm run dev

Step 5: Run Tests

npm test -- as4-settlement.test.ts

---

Next Steps Summary

Immediate Actions Required

1. Start Database Server (if stopped)

   # On database server
   sudo systemctl start postgresql
   

2. Check Network Connectivity

   ping 192.168.11.105
   nc -zv 192.168.11.105 5432
   

3. Verify Firewall Rules

   # On database server
   sudo ufw allow 5432/tcp
   # or check iptables
   sudo iptables -L -n | grep 5432
   

4. Test Connection

   psql postgresql://dbis:***@192.168.11.105:5432/dbis_core -c "SELECT 1;"
   

Once Database is Available

1. Run migration: npx prisma migrate deploy
2. Seed marketplace: npx ts-node scripts/seed-as4-settlement-marketplace-offering.ts
3. Verify setup: ./scripts/check-database-status.sh
4. Start server: npm run dev
5. Test endpoints: ./scripts/test-as4-api.sh
