Ensuring sufficient system linkage indexes
The RTCS subsystem requires only one system linkage index (LX). Additional system LX are reserved for use by authorized applications and products on this system image. These are specified by the NSYSLX parameter in the IEASYSxx member of SYS1.PARMLIB or a z/OS system image Logical PARMLIB data set.
We recommend that you ensure the sufficient system linkage indexes are available. If you have difficulty starting RTCS because no system LXs are available, increase the value of the NSYSLX parameter, and reIPL the z/OS image.
