Couple of things to check:
1. The supplied OAS credentials (usually oc4jadmin) are correct
2. OAS was installed with the "make this an administrative install" option was selected, which ensures ascontrol was installed. Best to leave the OC4J instance name for this as "home"
3. Ensure the home instance is running. Stopping, then starting the OAs instance (OPMN) using server manager will ensure this.
Note: 10.1.2.x is not supported with 8.97.
