Selecting default data set option members

This topic describes how to work with default data set option members through the AR/CTL ISPF interface.

If you need more information about any of these steps, see Introduction.

1. Access the BMC AMI APPLICATION RESTART CONTROL primary menu.
2. Type 10 (Program and data set options) in the choice entry field.

3. Press Enter. AR/CTL displays the Data Set and Program Options panel.

   ARCPPDC0       Data Set and Program Options (FCBs and ASBs)
    Command ===> _________________________________________________________________
                                                                                 
    Select an option. Type library information. Then press Enter.                 
                                                                                 
      _  1. Default data set option (FCB) members                                 
         2. Data set option (FCB) members                                         
         3. Program option (ASB) members

    Program option (ASB) library   PAG.ARC.ASBLIB_______________________________
4. Type 1 in the choice entry field.
5. Type or verify the data set name of the library that contains (or will contain) the data set option members you want to work with. Allocation parameters for this library should be appropriate for load module libraries (for example, DSORG=PO, RECFM=U, LRECL=0, BLKSIZE=6144 ). It can be the same library as the program option library. Do not use the AR/CTL load library to store data set option members.

6. Press Enter. AR/CTL displays the List Members panel, which works the same way as the List Records panel.The panel lists the names of the existing default data set option members in the library. AR/CTL uses the following names for default data set option members:

   Name	Description
   LOCVDFLT	default data set option member for a VSAM data set that uses AR/CTL local VSAM access services
   QSAMDFLT	default data set option member for a data set that uses AR/CTL sequential file interception services
   RMTVDFLT	default data set option member for a VSAM data set that uses AR/CTL remote VSAM access services

   No default data set option member is available for ASAM data sets; if you want to use values other than the internal defaults, you must create a specific data set option member for the data set.

7. Use one of the following commands or action codes to indicate the action to take:

   • To display an existing member and possibly update it, type action code S in the Act field of the row that lists the member.

   • To delete an existing member, enter action code D in the Act field of the row that lists the member. Or enter the following command on the command line (you can omit the member name from the command):

     DEL member

     Error

     Warning

     A default data set option member may be used by multiple application programs. Before you delete the member, be sure that no application program needs it.

   • To create a new default data set option member, enter the following command on the command line:

     ADD

8. Press Enter.
   • If you selected an existing member to display, AR/CTL displays one of these panels, depending on the type of member:
     • Sequential Data Set Options
     • Local VSAM Data Set Options
     • Remote VSAM Data Set Options
   • If you selected an existing member to delete, AR/CTL displays the Delete Member panel (not shown), which works the same way as the Delete Record panel, to confirm the deletion. If you omitted the member name from the command, AR/CTL displays the Delete Member Name panel (not shown) to request the name, and then displays the Delete Member panel.

   • If you entered the add command, AR/CTL displays the Select Default Data Set Type panel to request the type of member to add. If the data set options library already contains a member of this type, AR/CTL redisplays the Select DEFAULT Data Set Option (FCB) Members panel with a message indicating that the member already exists. AR/CTL automatically determines the member name when you choose the member type.

           3. Remote VSAM data set defaults

     
     

9. If you are adding a new member, type one of the following values in the choice entry field on the Select Default Data Set Type panel, and press Enter:

   Value	Description
   1	Add the default member for sequential data sets that use sequential interception services; the member name is QSAMDFLT. AR/CTL displays the Sequential Data Set Options panel.
   2	Add the default member for VSAM data sets that use local VSAM access services; the member name is LOCVDFLT. AR/CTL displays the Local VSAM Data Set Options panel.
   3	Add the default member for VSAM data sets that use remote VSAM access services; the member name is QSAMDFLT. AR/CTL displays the Remote VSAM Data Set Options panel.
