JES2Mail is designed to automate the distribution of JES output via email within z/OS environments. It operates as a batch job step, a z/OS UNIX directory monitor, or a JES output monitor. The core components include the JES2Mail execution module, which processes JES output, the format conversion module, which transforms output into PDF, HTML, or XML, and the email transmission module, which sends the formatted output via SMTP.
These components communicate through internal z/OS data structures and system services. Configuration is managed through parameters passed to the JES2Mail program during execution. For example, the `PARM` keyword in JCL specifies the input data set, output format, and recipient email addresses.
JES2Mail integrates with z/OS security features for authentication and authorization, operating within the security context of the z/OS environment. It does not expose public APIs like REST or SOAP; integration is achieved through direct invocation within z/OS batch jobs or via directory monitoring. Competing products may offer broader integration capabilities, but JES2Mail focuses on seamless integration with z/OS environments.
It leverages standard z/OS facilities for data access and storage, reading JES output using standard z/OS data set access methods. JES2Mail enhances efficiency by automating report distribution and reducing printing costs.
