The XSYS option on the GQSCAN macro allows the GQSCAN issuer to indicate whether cross-system processing is required. The default is XSYS=YES. You can specify the option XSYS=NO to turn cross-system processing off for that particular GQSCAN request. If you specify the no cross-system option, XSYS=NO, only the global resource information for the caller's system is returned. This type of GQSCAN can run under the caller's task, without causing the unit of work to be suspended.

Specifying XSYS=NO benefits users of GQSCAN that cannot be suspended and do not require data about requesters on other systems in the complex.
