– System JRE — Enables use of the JRE installed on the system. Select the required version 
from the drop-down list.
NOTE: If the JRE does not exist on the system on which Server Administrator is running, the 
JRE provided with the Server Administrator is used.

X.509 Certificate Management
NOTE: You must be logged in with Administrator privileges to perform certificate management.
Web certificates are necessary to ensure the identity of a remote system and ensure that information 
exchanged with the remote system are not viewed or changed by others. To ensure system security, it is 
recommended that:
• You generate a new X.509 certificate, reuse an existing X.509 certificate or import a certificate chain 
from a Certification Authority (CA).
• All systems that have Server Administrator installed have unique host names.
To manage X.509 certificates through the Preferences home page, click General Settings, click the Web 
Server tab, and click X.509 Certificate.
The following are the available options:
• Generate a new certificate — Generates a new self-signed certificate used for SSL communication 
between the server running Server Administrator and the browser.
NOTE: When using a self-signed certificate, most web browsers display an untrusted warning as 
the self-signed certificate is not signed by a Certificate Authority (CA) trusted by the operating 
system. Some secure browser settings can also block the self-signed SSL certificates. The Server 
Administrator web GUI requires a CA-signed certificate for such secure browsers.
• Certificate Maintenance — Allows you to generate a Certificate Signing Request (CSR) containing all 
the certificate information about the host required by the CA to automate the creation of a trusted 
SSL web certificate. You can retrieve the necessary CSR file either from the instructions on the 
Certificate Signing Request (CSR) page or by copying the entire text in the text box on the CSR page 
and pasting it in the CA submit form. The text must be in the Base64–encoded format.
NOTE: You also have an option to view the certificate information and export the certificate that 
is being used in the Base64–encoded format, which can be imported by other web services.
• Import certificate chain — Allows you to import the certificate chain (in PKCS#7 format) signed by a 
trusted CA. The certificate can be in DER or Base64-encoded format.
• Import a PKCS12 Keystore — Allows you to import a PKCS#12 keystore that replaces the private key 
and certificate used in Server Administrator web server. PKCS#12 is public keystore that contains a 
private key and the certificate for a web server. Server Administrator uses the Java KeyStore (JKS) 
format to store the SSL certificates and its private key. Importing a PKCS#12 keystore to Server 
Administrator deletes the keystore entries, and imports a private key and certificate entries to the 
Server Administrator JKS.
NOTE: An error message is displayed if you either select an invalid PKCS file or when you type an 
incorrect password.
SSL Server Certificates
Server Administrator Web server is configured to use the industry-standard SSL security protocol to 
transfer encrypted data over a network. Built on an asymmetric encryption technology, SSL is widely
