Working with large filters
To improve performance for large filters, you can limit the number of data sets that are displayed in the Remote Systems view.
To reduce excessive CPU consumption
on the z/OS® host, the z/OS system administrator can limit
the number of results that MVS data
set filters can return. If this limit is reached, a warning message
The number of returned data sets exceeds <limit>. is displayed,
where the <limit> is the number of results specified by the z/OS system administrator. The
"Locate" function cannot locate data sets or members that fall beyond
the limit of filter search results. Modify your MVS data set filters to reduce the number of
results they produce so that the limit is not triggered.
