To improve performance for large filters, Rational® Developer for System z® can limit the number of data sets
that display in the Remote Systems view. This
topic explains how to work with large filters.
About this task
When the default settings for the MVS™ Files subsystem are in effect and a filter
is expanded, the Remote Systems view displays a maximum of 50 data
sets. You can take the following actions to browse through the data
sets.
Note: The examples in this topic use a smaller filter for purposes
of illustration.
Procedure
- Displaying additional data sets:
When
you first expand a large filter, the data sets in excess of 50 are
shown using placeholders:- To show additional data sets, double-click the placeholder. The next 50 data sets display and a placeholder is shown
for the previous 50 data sets:
- To continue to browse up and down through the data sets,
double-click either the top or the bottom placeholder. You
can also browse through data sets by doing the following actions:
- Select a filter name and then select Navigate > Top, Navigate
> Bottom, Navigate > Previous, or Navigate
> Next from the pop-up menu.
- Select a filter name, data set name, or placeholder and then press
the shortcut keys Ctrl+Home (top), Ctrl+End (bottom), Ctrl+PgUp (previous),
or Ctrl+PgDn (next).
- Locating a data set: To locate a specific data set,
do these steps.
Note: To use the Locate command,
you need to set the Sort Order for Data Sets option
on the MVS Files Preference page to By
name. Otherwise, the sort order will be changed to By
name temporarily until the filter is refreshed.
- Select the filter name, and then select Locate from
the pop-up menu or press shortcut key Ctrl+L.
- In the Locate Data Set window,
specify the data set name you want to locate and click OK. You can specify a partial data set name, such as HLQ. If
the name you search for does not exist, the data set name just before
the search string is located. Previous searches are preserved and
added to a drop-down list in the Locate Data Set window.
You can select a previous search string from this list. The data set name found is displayed and highlighted:
- Changing the number of data sets to display: To
change the numbers of data sets to display for a filter, do one of
the following actions:
- Select a place holder and then select Show More or Show
Less from the pop-up menu. A window opens prompting you
to specify the number of data sets to display.
- Select a filter name and then select Properties from
the pop-up menu. On the Properties page, select Expansion and
specify the number of data sets to display in the Expansion
page size field.
