Overview

This guide helps you resolve common connection issues when connecting Koala Data Explorer to Oracle Fusion Cloud.

​
Common Connection Problems

​
”Authentication Failed”

​
Basic Authentication Issues

Symptoms:
  • Login fails with correct username/password
  • “Invalid credentials” error message
Solutions:
  1. Verify credentials: Double-check username and password
  2. Check account status: Ensure account is not locked or expired
  3. Test in browser: Try logging into Oracle Fusion web interface
  4. Contact administrator: Verify account has appropriate permissions

​
OAuth PKCE Issues

Symptoms:
  • OAuth flow fails during authentication
  • Browser doesn’t redirect back to VS Code
Solutions:
  1. Check client configuration: Verify OAuth client ID and settings
  2. Clear browser cache: Remove cached OAuth tokens
  3. Verify redirect URL: Ensure vscode://btss.koala-data-explorer/oauth-callback is configured
  4. Network restrictions: Check if corporate firewall blocks OAuth flows

​
”Connection Timeout”

Symptoms:
  • Connection takes too long and fails
  • Timeout error messages
Solutions:
  1. Check network connectivity: Verify internet connection
  2. VPN issues: Ensure VPN is connected if required
  3. Firewall settings: Verify HTTPS traffic is allowed
  4. Increase timeout: Adjust timeout settings in extension preferences
  5. Try different network: Test on different network connection

​
”Host Not Found” / “Invalid URL”

Symptoms:
  • Cannot resolve Oracle Fusion hostname
  • “Host not found” error
Solutions:
  1. Verify URL format: Ensure URL starts with https://
  2. Check instance URL: Confirm correct Oracle Fusion instance URL
  3. DNS issues: Try accessing URL in browser first
  4. Corporate network: May need to use internal URLs on corporate networks

​
Proxy Settings

If your organization uses a proxy:
  1. VS Code proxy settings: Configure in VS Code settings
  2. System proxy: Ensure system proxy is configured correctly
  3. Authentication: Proxy may require separate authentication
  4. Bypass list: Add Oracle Fusion domains to proxy bypass

​
SSL/TLS Issues

Symptoms:
  • SSL certificate errors
  • “Insecure connection” warnings
Solutions:
  1. Certificate verification: Ensure valid SSL certificates
  2. Corporate certificates: Install corporate root certificates
  3. TLS version: Verify TLS 1.2+ is supported
  4. Contact IT: May need corporate certificate configuration

​
Permission Issues

​
Database Access

Symptoms:
  • Connection succeeds but queries fail
  • “Insufficient privileges” errors
Solutions:
  1. Verify SELECT permissions: Ensure user has SELECT rights on required tables
  2. Schema access: Check access to specific schemas
  3. Role assignments: Verify proper Oracle Fusion roles are assigned
  4. Data security: Check if row-level security policies apply

​
Application Access

Symptoms:
  • Cannot access specific Oracle Fusion modules
  • Limited data visibility
Solutions:
  1. Module licenses: Verify licenses for required modules
  2. User provisioning: Ensure user is provisioned for specific applications
  3. Security roles: Check Oracle Fusion security role assignments
  4. Data access sets: Verify appropriate data access sets are assigned

​
Environment-Specific Issues

​
Development vs Production

Common differences:
  • Different authentication methods
  • Network restrictions
  • Data access permissions
  • URL formats
Solutions:
  1. Environment-specific connections: Create separate connections for each environment
  2. Check documentation: Verify environment-specific connection details
  3. Contact administrators: Different environments may have different requirements

​
Multi-tenant Environments

Issues:
  • Wrong tenant/pod connections
  • Cross-tenant data access restrictions
Solutions:
  1. Verify tenant URL: Ensure connecting to correct tenant
  2. Tenant-specific authentication: May require different credentials per tenant
  3. Data isolation: Understand tenant data boundaries

​
Performance Issues

​
Slow Connections

Symptoms:
  • Connection takes long time to establish
  • Queries run slowly
Solutions:
  1. Network latency: Check ping times to Oracle Fusion
  2. Geographic location: Connection speed varies by location
  3. Peak usage times: Avoid peak usage periods
  4. Query optimization: Use efficient queries with appropriate limits

​
Connection Drops

Symptoms:
  • Frequent disconnections
  • Need to reconnect often
Solutions:
  1. Network stability: Check for network interruptions
  2. Idle timeouts: Oracle may disconnect idle sessions
  3. Firewall timeouts: Corporate firewalls may drop long connections
  4. Keep-alive settings: Configure connection keep-alive if available

​
Windows SSO Issues

​
Common Problems

“Runtime components missing”
  • Accept the download prompt when shown by the extension
  • Restart VS Code after installation
“SSO dialog won’t open”
  • Restart VS Code completely
  • Check with IT if antivirus software is blocking connections
“Authentication timeout”
  • Verify SSO works in your regular browser first
  • Contact Oracle administrator if SSO login fails
  • Try connecting again after a few minutes
“Download failed”
  • Check internet connection
  • Contact IT support if corporate firewall blocks downloads

​
Diagnostic Steps

​
Basic Diagnostics

  1. Test in browser: Try accessing Oracle Fusion in web browser
  2. Network connectivity: Ping Oracle Fusion hostname
  3. Port accessibility: Verify HTTPS (443) port is accessible
  4. DNS resolution: Verify hostname resolves correctly

​
Advanced Diagnostics

  1. Network traces: Use network monitoring tools
  2. SSL handshake: Verify SSL negotiation succeeds
  3. Authentication flow: Debug OAuth or SAML flows
  4. Log analysis: Check VS Code and extension logs

​
