title: Referring external file in TNSORANAMES.ora
body: <p>I am trying to write  a VB script to add/edit/delete some entries in tnsnames.ora. It will be convenient to refer/modify an external file (say myProjectOraNames.ora) rather than modifying tnsnames.ora</p>
  
  <p>With this configuration (assuming it is possible), the Oracle client should refer to both the existing tnsnames.ora file and my new myProjectOraNames.ora to get service details.</p>
  
  <p>Is there any option/configuration can be done to achieve this functionality? </p>
