Gateway software components

The two z/OS program components of the HCL Workload Automation gateway are:

EEWTCP02

This program establishes that HCL Workload Automation is tracking on the z/OS system. The program is started by the EEWSPACE job.

EEWTCP00

This is the “gateway” program that manages TCP/IP communications between HCL Workload Automation and the z/OS system. It is started by the EEWSERVE job. EEWTCP00 translates HCL Workload Automation commands to z/OS equivalents, routes z/OS information back to HCL Workload Automation, and performs EBCDIC-ASCII data conversions.

Both of the programs run as started tasks, with a TIME=NOLIMIT parameter. EEWTCP02 is always started first, followed by EEWTCP00. If the programs must be stopped for any reason, they should be stopped, not canceled, to ensure that they shut down properly without impacting other programs that use the IEFU84 Exit.
