High availability (failover) for XCOM for z/OS and LUW platforms

Products

• XCOM Data Transport
• XCOM Data Transport - z/OS
• XCOM Data Transport - Windows
• XCOM Data Transport - Linux PC

Issue/Introduction

Need information on a high availability (failover) solution for XCOM for z/OS and XCOM for Linux, Unix, Windows (LUW) platforms.
Can XCOM be used in load balancing or OS clustering?

Environment

• XCOM™ Data Transport® for z/OS
• XCOM™ Data Transport® for Windows
• XCOM™ Data Transport® for UNIX/Linux PC

Resolution

The XCOM for z/OS PLEXQ facility can be used to link multiple XCOM servers together using IBM Parallel Sysplex Signaling Services.

Relevant XCOM for z/OS documentation sections:
XCOM™ Data Transport® for z/OS 12.0 > Administrating > Best Practices > PLEXQ Facility
XCOM™ Data Transport® for z/OS 12.0 > Administrating > Understanding the PLEXQ
XCOM™ Data Transport® for z/OS 12.0 > Installing > Optional Configuration Procedures > Create a PLEXQ Environment


There is no high official availability support for XCOM for Linux/UNIX although for XCOM for Windows, this is documented:
XCOM™ Data Transport® for Windows 11.6 Service Packs > Administrating > High Availability / Failover Support on Windows
XCOM™ Data Transport® for Windows 12.0 > Administrating > High Availability / Failover Support on Windows

A load balancer can be used with other XCOM platforms.
