  • The MID Server JVM can utilize a TrustStore external to the MID installation directory so any certificates added to the TrustStore are not overwritten during an upgrade. It is important that this TrustStore file reside outside of the MID installation directory, and the Truststore location can be specified by adding additional parameters to the MID Server's wrapper-override.conf file.

    Before you begin

    Role required: admin

    Procedure

    1. In the MID Server host, navigate to the wrapper-override.conf file.
    2. Specify an external TrustStore by appending a custom parameter to the end of your MID’s wrapper-override.conf file.
      For example, on a Windows MID with an external TrustStore found at C:\external_truststore\cacerts, the end of the file would appear similar to:
      # Add additional custom parameters below
      
      wrapper.java.additional.3=-Djavax.net.ssl.trustStore=C:\external_truststore\cacerts
      
      wrapper.java.additional.4=-Djavax.net.ssl.trustStorePassword=<truststore’s password>
      Note:
      If you have specified other additional parameters in this file then the numerical identifier, in this case 3 and 4, may differ.
