5.5.1. Using Property Value Substitution With System Properties

You can use property value substitution in conjunction with the system properties, to modify the configuration according to the system on which the OpenIDM instance runs.

Example 5.2. 

The following example modifies the audit.json file so that the log file is written to the user's directory. The user.home property is a default Java System property. 

{
    "logTo" : [
        {
            "logType" : "csv",
            "location" : "&{user.home}/audit",
            "recordDelimiter" : ";"
        }
    ]
}

You can define nested properties (that is a property definition within another property definition) and you can combine system properties and boot properties.

Example 5.3. 

The following example uses the user.country property, a default Java System property. The example defines specific LDAP ports, depending on the country (identified by the country code) in the boot.properties file. The value of the LDAP port (set in the provisioner.openicf-ldap.json file) depends on the value of the user.country System property.

The port numbers are defined in the boot.properties file as follows: 

   openidm.NO.ldap.port=2389
   openidm.EN.ldap.port=3389
   openidm.US.ldap.port=1389

The following extract from the provisioner.openicf-ldap.json file shows how the value of the LDAP port is eventually determined, based on the System property: 

   "configurationProperties" :
   {
      "credentials" : "Passw0rd",
      "port" : "&{openidm.&{user.country}.ldap.port}",
      "principal" : "cn=Directory Manager",
      "baseContexts" :
         [
            "dc=example,dc=com"
         ],
      "host" : "localhost"
   }
