Our colleagues in Oracle Identity Management (IDM) recently announced that all SIMPLE mode certificates used with Oracle Access Manager (OAM) and OAM WebGate will expire in March 2024. After this time, all OAM components using SIMPLE mode certificates for communication will not function and may cause an outage in your environment. Therefore, Oracle IDM recommends you begin your preventive process promptly to prevent a service disruption.
