Web Service Scheme and Web Service Port are wrong

CAPM 3.x

The following steps should be followed to change Web Service Scheme and Web Service Port

• cd /opt/CA/PerformanceCenter
• ./SSOConfig
  - Choose 1. CA Performance Center
  - Choose 3. Performance Center
  - The following items need to change: Web Service Scheme: https / Web Service Port: 8382
• Choose 2. Local Override ... "Update" Web Service Scheme: https to http
  - b .... for back
  - Choose 1. Remote Value ... "Update" Web Service Scheme: https to http / "Update" Web Service Port: 8382 to 8481
  - b .... for back
  - So when you once again choose 3. Performance Center it should show: Web Service Scheme: http / Web Service Port: 8481
• Re sync event manager in the CAPC UI

The error should now go away and event manager will receove the full inventory from device manager
