Can the SSL METHOD be changed within a batch job

Products

• XCOM Data Transport - z/OS

Issue/Introduction

How can I specify in a batch job the SSL METHOD to be used for a particular connection, we have defined value ALL in our configuration for the INIT SIDE=. Is there a way, with a parameter in the job to use SSL METHOD TLS v1.2 ?

Environment

Release : 12.0

Component : XCOM Data Transport for z/OS

Resolution

The SSL METHOD can only be specified in the SYSconfigSSL.cnf file. XCOM will use the SYSconfigSSL.cnf  specified on the CONFIG parameter XCOM_CONFIG_SSL=.

In other words, the XCOM task will use the value specified for XCOM_CONFIG_SSL= for all TYPE=SCHEDULE and incoming transfers. It would require that the XCOM task be recycled if the value of the parameter is changed in the CONFIG member.

You can specify a specific SYSconfigSSL.cnf using the XCOM_CONFIG_SSL= parameter in the SYSIN01 for a TYPE=EXECUTE transfer. This will only be in effect for that specific transfer. As a reminder, the remote partner will need to have the proper value for SSL METHOD if you are specifically wanting to test TLS v1.2.
