Defining a new Catalog Entry

You can define a new catalog entry, using an existing entry as a model, or you can define a new entry without a model and specify all of the required fields yourself. If you define a new non-VSAM catalog entry, you must choose to either only define the catalog entry or define the entry and allocate the data set.

To define a new catalog entry using an existing catalog entry as a model:

  1. In the Catalog Services panel:
    1. Type the data set name (and optionally the catalog name) for the existing entry.
    2. To run the define function in batch, select the Batch execution option.
    3. Enter DEF on the Command line.
    4. Press Enter.
    5. If you are defining an alternate index for a VSAM file (AIX), you can also request that the newly defined AIX is built following the define, or that an existing AIX is deleted, redefined and rebuilt. The define, build and redefine functions are available for online and batch processing.

      When you define an alternate index for a VSAM file (AIX), File Manager displays a pop-up panel as shown in Catalog Services panel.

      Select the type of AIX® processing you want:
      • To define an AIX, select 1. AIX define only.
      • To define and build an AIX, select 2. AIX define and build.
      • To delete, recreate, and then rebuild an existing AIX, select 3. AIX redefine and rebuild.

    A Define panel for the entry type of your existing data set is displayed, containing the information copied from your model. For example, if your existing data set was a VSAM KSDS file, the VSAM Define panel is displayed.

  2. Alter the contents of the Data set name field to specify a new, unique data set name.
  3. For the Catalog ID field:
    • If SMS is active on the system, the new value for the catalog ID is copied from the model data set but prefixed with an asterisk (*) to indicate a comment value. this value is ignored unless you remove the asterisk.
    • If SMS is not active on the system, the catalog name is copied from the model data set.
    Do one of the following:
    • Blank the field out, to allow the system to assign your data set using the catalog selection order for IDCAMS DEFINE.
    • Remove the asterisk (*) from the existing entry, to assign your data set to the same catalog.

      If the specified catalog is not the same as the related user catalog for this Entry type, a warning message is issued. You can Exit from the message (F3) and change or blank out the catalog name, or you can press Enter to continue using the initial catalog name. If you choose to continue, you need to supply the catalog name in all future searches for the Entry.

    • Specify an alternative Catalog ID.
  4. For VSAM data sets, alter the component name or names, listed under the Basic Information heading, to unique names suited to your data set.

    OR

    Blank out the component name or names listed under the Basic Information heading. File Manager generates new component names based upon the following AMS rules:

    1. IF the last qualifier of the Entry data set name is CLUSTER, it replaces the last qualifier with DATA for the data component and INDEX for the index component. For example: 
      Cluster name: SALES.REGION2.CLUSTER
Generated data name = SALES.REGION2.DATA
Generated index name = SALES.REGION2.INDEX
    2. ELSE if the cluster name is less than or equal to 38 characters, then append .DATA to the end of the cluster name for the data component and .INDEX for the index component. For example: 
      Cluster name: DEPT64.ASSET.INFO
Generated data name = DEPT64.ASSET.INFO.DATA
Generated index name = DEPT64.ASSET.INFO.INDEX
    3. ELSE if the cluster name is between 39 and 42 characters inclusive, then append .D to the end of the cluster name for the data component and .I for the index component. 
      Cluster name: DEPTABCD.RESOURCE.REGION66.DATA1234.STUFF
Generated data name = DEPTABCD.RESOURCE.REGION66.DATA1234.STUFF.D
Generated index name = DEPTABCD.RESOURCE.REGION66.DATA1234.STUFF.I
    4. ELSE if the name is longer than 42 characters, and the last qualifier is not CLUSTER, use the first (N-1) qualifiers of the cluster, alternate index, or user catalog name up to the first four qualifiers, and append as many 8-character qualifiers as necessary to produce a 5-qualifier name. For example: 
      Cluster name: DIV012.GROUP16.DEPT98.DAILYLOG.DEC1988.BACK
Generated data name = DIV012.GROUP16.DEPT98.DAILYLOG.TY7RESNO
Generated index name = DIV012.GROUP16.DEPT98.DAILYLOG.YIIQHNTR

    After a name is generated, AMS searches the catalog to ensure that the name is unique. If a duplicate name is found, AMS continues generating new names using the format outlined in 4.d until a unique one is produced.

  5. Alter any of the remaining parameters (copied from the existing entry) to suit your new entry.
  6. Press Enter to process your define request.

To define a new catalog entry without an existing catalog entry as a model:

  1. In the Catalog Services panel:
    1. Type a new, unique data set name (and optionally a Catalog ID).
    2. Select your Entry Type option.
    3. To run the define function in batch, select the Batch execution option.
    4. Enter DEF on the Command line.
    5. If you are defining an alternate index for a VSAM file (AIX), you can also request that the newly defined AIX is built following the define, or that an existing AIX is deleted, redefined and rebuilt. The define, build and redefine functions are available for online and batch processing.
      When you define an alternate index for a VSAM file (AIX), File Manager displays a pop-up panel as shown in Catalog Services panel. Select the type of AIX processing you want:
      • To define an AIX, select 1. AIX define only.
      • To define and build an AIX, select 2. AIX define and build.
      • To delete, recreate, and then rebuild an existing AIX, select 3. AIX redefine and rebuild.
    6. Press Enter.

    You might be prompted to further refine your entry type, depending on which Entry Type you selected.

    A Define panel for the entry type that you selected is displayed. If this is the first catalog entry you have defined in your current session, the fields in this panel are empty. If you have previously defined a catalog entry with the same type, the field information is pre-filled with the values last used in the panel.

  2. Supply the required values and press Enter to process the define request. (File Manager prompts you to complete all of the required fields).
