Procedure

To set preferences for MVS Files:

  1. To open the MVS Files preference page, click Window > Preferences, then expand the Remote Systems and z/OS sections and click MVS Files.
  2. Use the MVS Files page to set the following preferences:
    Large Partitioned Data Set
    The options in this area determine how large partitioned data sets are handled in the Remote Systems view.
    Show warning message on expansion
    Select this check box to display a warning message when expanding large partitioned data sets, which can take a long time.
    Maximum number of members expanded without warning
    If you select the Show warning message on expansion option, use this field to set the number of members to allow before the warning is displayed. The default value is 5000.
    Show warning message on adding to subproject
    Select this check box to display a warning message when adding large partitioned data sets to a subproject.
    Maximum number of members added to subproject without warning
    If you select the Show warning message on adding to subproject option, use this field to set the number of members to allow before the warning is displayed. The default value is 50.
    Maximum results for Find Member
    Specify the maximum number of search results to return with the Find Member action. The default value is 1000 members.
    Generation Data Set Label
    There are two options for displaying generation data sets:
    • Absolute generation and version numbers (Relative generation number): Shows the absolute generation and version numbers followed by the relative generation number, such as G0005V00(-1).
    • Relative generation number (Absolute generation and version numbers): Shows the relative generation number followed by the absolute generation and version number, such as -1(G0005V00).
    Sort Order for Data Sets
    The options in this area determine the order of data sets in the Remote Systems view and the z/OS Projects or Enterprise Projects view:
    • By type: Select this option to list partitioned data sets followed by sequential data sets.
    • By name: Select this option to list all data sets in alphabetical order, regardless of data set type.
    Default expansion page size for filters and data sets
    Specify the number of data sets or data set members to show in the Remote Systems view when you expand a filter or partitioned data set. All other entries remain hidden until you take an action to bring them into view. You can override this number for a particular filter or data set. The default value is 50.
    Show warning message on deleting alias
    Select this check box to display a warning message when you delete a data set alias.
    Process member aliases on module copy
    Select this check box to enable the primary load module and all its aliases to be copied together.
    Show members with non-standard name
    Select this check box to enable the Remote Systems view to display members with lowercase names or names containing non-standard character sets. This option is disabled by default.
    Enable editing of files with control codes:
    Select this check box to allow MVS™ text files that contain control codes to be opened in edit mode. When this check box is selected, UTF-8 is used as the default local code page mapping for new connections. Connections that already exist are not affected.
