Generate a certificate request. Note that when you create a new wallet with Oracle Wallet Manager, the tool automatically prompts you to create a certificate request. Send the certificate request to the CA you want to use. You can copy and paste the certificate request text into an e-mail message, or you can export the certificate request to a file. The certificate request becomes part of your wallet.

It must remain there until you remove its associated certificate. When the CA sends your signed user certificate and its associated trusted certificate , then you can import these certificates in the following order. The user certificates and trusted certificates in the PKCS 7 format can be imported at the same time.

First import the CA's trusted certificate into your wallet. This step may be optional if the new user certificate has been issued by one of the CAs whose trusted certificate is already present in Oracle Wallet Manager by default.
