Replacing a certificate after upgrading OnCommand Insight

Opening the OnCommand Insight web UI after an upgrade results in a certification warning. The warning message is displayed because a valid self-signed certificate is not available after the upgrade. To prevent the warning message from being displayed in the future, you can install a valid self-signed certificate to replace the original certificate.

Before you begin

Your system must satisfy the minimum encryption bit level (1024 bits).

About this task

The certification warning does not impact the usability of the system. At the message prompt, you can indicate that you understand the risk, and then proceed to use Insight.


  1. List the contents of the keystore: C:\Program Files\SANscreen\java64\bin>keytool.exe -list -v -keystore "c:\Program Files\SANscreen\wildfly\standalone\configuration\server.keystore"
    When prompted for a password, enter changeit.
    There should be at least one certificate in the keystore, ssl certificate.
  2. Delete the ssl certificate: keytool -delete -alias ssl certificate -keystore c:\ProgramFiles\SANscreen\wildfly\standalone\configuration\server.keystore
  3. Generate a new key: keytool -genkey -alias -keyalg RSA -keysize 2048 -keystore "c:\ProgramFiles\SANscreen\wildfly\standalone\configuration\server.keystore"
    1. When prompted for first and last names, enter the fully qualified domain name (FQDN) that you intend to use.
    2. Provide the following information about your organization and organizational structure:
      • Country: two-letter ISO abbreviation for your country (for example, US)
      • State or Province: name of the state or province where your organization's head office is located (for example, Massachusetts)
      • Locality: name of the city where your organization's head office is located (for example, Waltham)
      • Organizational name: name of the organization that owns the domain name (for example, NetApp)
      • Organizational unit name: name of the department or group that will use the certificate (for example, Support)
      • Domain Name/ Common Name: the FQDN that is used for DNS lookups of your server (for example,
      The system responds with information similar to the following: Is, OU=support, O=NetApp, L=Waltham, ST=MA, C=US correct?
    3. Enter Yes when the Common Name (CN) is equal to the FQDN.
    4. When prompted for the key password, enter the password, or press the Enter key to use the existing keystore password.
  4. Generate a certificate request file: keytool -certreq -alias localhost -keystore "c:\Program Files\SANscreen\wildfly\standalone\configuration\server.keystore" -file c:\localhost.csr
    The c:\localhost.csr file is the certificate request file that is newly generated.
  5. Submit the c:\localhost.csr file to your certification authority (CA) for approval.
    Once the certificate request file is approved, you want the certificate returned to you in .der format. The file might or might not be returned as a .der file. The default file format is .cer for Microsoft CA services.
  6. Import the approved certificate: keytool -importcert -alias localhost -file c:\localhost2.DER -keystore "c:\Program Files\SANscreen\wildfly\standalone\configuration\server.keystore"
    1. When prompted for a password, enter the keystore password.
      The system displays the following message: Certificate reply was installed in keystore
  7. Restart the SANscreen Server service.
