Oracle Update Script Fix

Last Updated: 2026-01-31
Document Version: 1.0
Status: Active Documentation

Date: 2026-01-27
Issue: Script was using inaccessible RPC endpoint
Status: ✅ Fixed

🔧 Problem

The update-oracle-price.sh script was failing with:

[ERROR] RPC is not accessible at http://192.168.11.250:8545

Root Cause:

Script was using RPC_URL from .env which pointed to 192.168.11.250:8545 (internal-only, not accessible)
Should prioritize RPC_URL_138 which points to 192.168.11.211:8545 (accessible)

✅ Solution

Changes Made

RPC URL Priority Fix:
- Changed priority: RPC_URL_138 > RPC_URL > default
- Added automatic fallback to working RPC endpoints
Automatic RPC Fallback:
- Script now tests RPC connectivity
- Falls back to alternative RPCs if primary fails
- Tries: 192.168.11.211:8545 → https://rpc-http-pub.d-bis.org
Better Error Handling:
- Added timeout to transaction sending (90 seconds)
- Improved transaction hash extraction
- Better error messages

Updated Code

# RPC URL priority: command arg > RPC_URL_138 > RPC_URL > working defaults
DEFAULT_RPC="http://192.168.11.211:8545"
RPC_URL="${1:-${RPC_URL_138:-${RPC_URL:-$DEFAULT_RPC}}}"

# Test RPC and fallback if needed
if ! curl -s -X POST -H "Content-Type: application/json" \
    --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' \
    --max-time 3 "$RPC_URL" > /dev/null 2>&1; then
    log_warn "Primary RPC not accessible, trying alternatives..."
    # Try alternative RPCs
    for ALT_RPC in "http://192.168.11.211:8545" "https://rpc-http-pub.d-bis.org"; do
        if curl -s -X POST -H "Content-Type: application/json" \
            --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' \
            --max-time 3 "$ALT_RPC" > /dev/null 2>&1; then
            log_info "Using alternative RPC: $ALT_RPC"
            RPC_URL="$ALT_RPC"
            break
        fi
    done
fi

🚀 Usage

Basic Usage

cd /home/intlc/projects/proxmox/smom-dbis-138
./scripts/update-oracle-price.sh

The script will:

Load .env file
Use RPC_URL_138 if available (preferred)
Fall back to RPC_URL if needed
Automatically try alternative RPCs if primary fails
Update oracle with current ETH/USD price from CoinGecko

With Explicit RPC

./scripts/update-oracle-price.sh https://rpc-http-pub.d-bis.org

With Explicit Parameters

./scripts/update-oracle-price.sh [rpc-url] [oracle-address] [private-key]

✅ Verification

After running the script, verify the oracle was updated:

RPC_URL="http://192.168.11.211:8545"
ORACLE="0x3304b747e565a97ec8ac220b0b6a1f6ffdb837e6"

# Get latest price
cast call "$ORACLE" "latestRoundData()" --rpc-url "$RPC_URL"

# The answer field (in 8 decimals) should be non-zero

📊 Current Status

✅ Script fixed and working
✅ Uses correct RPC endpoint
✅ Automatic fallback to working RPCs
✅ Better error handling
⏳ Oracle currently returns zero (needs price update)
