To improve performance for large partitioned data sets, Rational® Developer for System z® can limit the number
of members that display in the Remote Systems view. This topic explains
how to work with large partitioned data sets.
When the default settings for the MVS Files subsystem are in effect and a partitioned
data set is expanded, the Remote Systems view displays a maximum of
50 partitioned data set members. You can take the following actions
to browse through the members of a large partitioned data set.
Note: The
examples in this topic use a smaller partitioned data set for purposes
of illustration.
- Displaying additional members:
When you
first expand a large partitioned data set, the members in excess of
50 are shown using placeholders:- To show additional members, double-click the placeholder. The next 50 members display and a placeholder is shown
for the previous 50 members:
- To continue to browse up and down through the members,
double-click either the top or the bottom placeholders. You
can also browse through members by doing the following actions:
- Select a partitioned data set name and then select Navigate
> Top, Navigate > Bottom, Navigate
> Previous, or Navigate > Next from
the pop-up menu.
- Select a partitioned data set name, member name, or placeholder
and then press the shortcut keys Ctrl+Home (top), Ctrl+End (bottom), Ctrl+PgUp (previous),
or Ctrl+PgDn (next).
- Locating a member: To locate a specific member name,
do these steps:
- Select the partitioned data set name, and then select Navigate
> Locate from the pop-up menu or press shortcut key Ctrl+L.
- In the Locate Member window, specify
the member name you want to locate and click OK. You can specify a partial member name, such as MEM. If
the name you search for does not exist, the member name just before
the search string is located. Previous searches are preserved and
added to a drop-down list in the Locate Member window.
You can select a previous search string from this list. The member name found is displayed and highlighted:
The Locate menu item is also available
on the z/OS Projects view.
- Changing the number of members to display: To
change the numbers of members to display for a partitioned data set,
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 members to display.
- Select a partitioned data set name and then select Properties from
the pop-up menu. On the Properties page, select Expansion and
specify the number of members to display in the Expansion
page size field.
