### 6. Docker Environment
**Status:** ✅ COMPLETE
- Docker daemon (OrbStack) running
- docker-compose.oracle.yml configured
- Container configuration verified
## ⏳ Pending: Oracle Container Startup
### Current Status
**Status:** IN PROGRESS
Oracle Docker image download is in progress:
- Image: `gvenzl/oracle-xe:18-slim` (attempting smaller version)
- Status: Pulling layers (network limited speed)
- Process: PID 17363
### Issue
Docker image download (~2GB+) taking longer than expected due to network bandwidth.
### Resolution Steps
**Option 1: Wait for current download (Recommended)**
```bash
# Monitor download progress
ps aux | grep "docker pull"
# Check when image is ready
watch -n 5 'docker images | grep oracle'
# Once complete:
cd /Users/linh.doan/work/harvey/freepeak/db-mcp-server
docker-compose -f docker-compose.oracle.yml up -d
# Wait for Oracle to initialize (1-2 minutes)
docker logs -f db-mcp-oracle-test
# Look for: "DATABASE IS READY TO USE!"
```
**Option 2: Download later and test then**
```bash
# Let it download in background
# Come back later and check:
docker images | grep oracle
# Then start container when ready
```
**Option 3: Use existing Oracle instance (if available)**
Update `config.json` with existing Oracle connection details instead.
## 🧪 Testing Procedure (Once Oracle is Ready)
### Quick Validation
```bash
cd /Users/linh.doan/work/harvey/freepeak/db-mcp-server
./quick-validate-oracle.sh
```
Expected output:
```
✓ Oracle container is running
✓ Oracle tools registered successfully
Available Oracle tools:
- query_oracle_dev
- execute_oracle_dev
- transaction_oracle_dev
- schema_oracle_dev
- performance_oracle_dev
====================================
✅ VALIDATION SUCCESSFUL
====================================
```
### OpenCode Testing
1. **Start OpenCode:**
```bash
cd /Users/linh.doan/work/harvey/freepeak/db-mcp-server
opencode
```
2. **Test Commands:**
```
# List all databases
use db-mcp-server to list all available databases
# Test Oracle connection
use query_oracle_dev to run: SELECT 'Hello from Oracle!' FROM DUAL
# Get database info
use query_oracle_dev to show me the database version
# Explore schema
use schema_oracle_dev to list all tables
# Create test table
use execute_oracle_dev to create table:
CREATE TABLE mcp_test (
id NUMBER PRIMARY KEY,
name VARCHAR2(100),
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
)
# Insert data
use execute_oracle_dev to insert into mcp_test values (1, 'test', CURRENT_TIMESTAMP)
# Query data
use query_oracle_dev to select * from mcp_test
# Analyze performance
use performance_oracle_dev to explain: SELECT * FROM mcp_test WHERE id > 0
```
## 📊 Test Results (Expected)
### Test 1: Connection Test
```sql
SELECT 'Hello from Oracle!' as message, SYSDATE as current_time FROM DUAL
```
**Expected:** Returns message and current database time
### Test 2: Schema Query
```sql
SELECT table_name FROM user_tables
```
**Expected:** Lists all user tables (initially may be empty)
### Test 3: DDL Operation
```sql
CREATE TABLE mcp_test (...)
```
**Expected:** Table created successfully
### Test 4: DML Operation
```sql
INSERT INTO mcp_test VALUES (...)
```
**Expected:** 1 row inserted
### Test 5: Query Operation
```sql
SELECT * FROM mcp_test
```
**Expected:** Returns inserted rows

## 📝 Summary
**Completed:** 7/9 items (78%)
**Remaining:** Oracle container startup and live testing
**All infrastructure is ready.** Once the Oracle Docker image finishes downloading and the container starts, you can immediately begin testing Oracle database operations through OpenCode using the db-mcp-server MCP tools.
**Estimated time to complete:** 5-10 minutes after image download finishes
## 🚀 Next Actions
1. **Immediate:** Wait for Oracle image download to complete
- Monitor: `ps aux | grep "docker pull"`
- Check: `docker images | grep oracle`
2. **Once Downloaded:** Start Oracle container
- Command: `docker-compose -f docker-compose.oracle.yml up -d`
- Monitor: `docker logs -f db-mcp-oracle-test`
3. **Once Ready:** Run validation
- Script: `./quick-validate-oracle.sh`
4. **Start Testing:** Launch OpenCode
- Command: `opencode`
- Test: Use db-mcp-server tools to query Oracle
