The following picture shows a model plan for implementation of SSL in ERP System
Any https client request from client desktop to web tier will be redirected to application server host. There is a firewall between the two i.e. web and application server are in different zone and due to https protocol any credentials or data will traverse as encrypted.
Pre Configuration Requirements
To use SSL in ERP System we need to fulfill the following requirements:-
1. We need a certificate and an Oracle wallet for each of our application and web server.
2. If admin decides to authenticate the clients, the clients will need certificates as well.
3. We need to configure Oracle Application Server components
4. SSL is resource-intensive. So in case of heavy SSL traffic, we should consider getting an SSL accelerator
Steps to perform
The below are the steps that are needed to be follow to implement SSL in ERP System.
All this steps has to be performed once for each of the application and web server in ERP System
1. Create a wallet
2. Create a Certificate Request (CSR)
3. Submit the Certificate Request to a Certifying Authority
4. Import the Server Certificate to the Wallet
5. Modify the OPMN wallet
6. Update the JDK Cacerts File
7. Update the Context File
8. Run Autoconfig
9. Restart the middle tier services
