RSMDATA HVSHRDATA subcommand output

The RSM high virtual shared data report (Figure 1) provides information about memory objects that are shared by the system. The report will also contain information about segments or regions that are shared including the view from each address space or the global view depending on the changeaccess scope of the memory object. The report is sorted by memory object virtual addresses. The first line for each memory object contains information about the GETSHARE invoker, followed by a list of address spaces currently sharing that memory object. If the memory object is shared with a global scope, the view for the segments and regions will follow the list of address spaces. The numbers in the top section of the report are hexadecimal. The totals at the bottom of the report are decimal.

SHARED ADDRESS RANGE

The range of virtual addresses to be used for shared memory objects.

S

An indication of the shared scope attribute:

L

The memory object is shared with a local scope.

G
