Importing the Server Certificate on Enterprise Manager

1. Obtain the root certificate listed under Root Certificate Authority - Entrust Root Certification Authority - G2, as shown in the following ServiceNow article:

2. Append the external Certificate Authority's certificate to:

   $INSTANCE_HOME/sysman/config/b64LocalCertificate.txt

3. Ensure that only the following is appended to the b64LocalCertificate.txt file (that is, do not include blank lines or comments or any other special characters):

   -----BEGIN CERTIFICATE----- <<<Certificate in Base64 format>>> -----END
             CERTIFICATE-----

4. Restart the OMS. Run the following commands:

   emctl stop oms
   emctl start oms 

Note:

Do not run the emctl secure oms/agent command after adding the external certificate to the b64LocalCertificate.txt file. If you run the emctl secure command later, then repeat the steps 1 through 3 to make sure the external certificate exists on the b64certificate.txt file.
