Environment

XCOM Data Transport® for z/OS

Cause

The SECURE_SOCKET parameter had been set to YES instead of NO.
Therefore XCOM was trying to looking for SYSTEM SSL configuration parameters like KEYRING_FILE in the XCOM_CONFIG_SSL file and not finding them.

Resolution

SECURE_SOCKET must be set to NO for AT-TLS per this article: Enabling encryption for XCOM for z/OS transfers using AT-TLS
i.e.
a. To initiate secure transfers using AT-TLS, you must not specify SECURE_SOCKET=YES in the XCOM parameters. The idea is that XCOM starts an unsecure transfer. AT-TLS makes it secure, XCOM notices the fact and issues messages informing that the connection is protected by AT-TLS. The transfers must be addressed to the SSL port at the partner.
