We need to have everyone use TLS V1.2 with XCOM.  



Is there a possible way so that we would not have to have all of our batch jobs updated?


Are there parameters that I can set in the config file that will make this happen?


Yes, you avoid updating all your JCL. 

  • Use SSL=ALLOW in the config file if you plan to run ANY SSL/TLS transfers.
  • Use SSL=ONLY to disallow non-SSL/TLS transfers altogether. 

As long as you use SystemSSL (a requirement for using TLSv1.2 on z/OS), even the non-SSL port will convert the conversation to use SSL if it is requested by the partner.
