Creating CICS VSAM tables and views for Classic federation

To query or update data in a CICS® VSAM file, you must create a relational table that maps to that file. You can also create a view on the table to filter record types or to filter rows and columns. You use the New CICS VSAM Table wizard to create the table and optionally the view.

You can map to the following types of VSAM files:

Procedure

To create a CICS VSAM table and optionally a view for Classic federation:

  1. Map your CICS VSAM file to a relational table and optionally a view by using the New CICS VSAM Table wizard.
    1. Open the wizard by right-clicking either the database in your data design project or one of the schemas within the database. Select Add Classic Object > CICS VSAM table.
    2. Select the copybook or include file to base the table on.
    3. Choose whether to use the table for queries, updates, or both.
    4. Choose whether to create a view on the table.
    5. Provide information about which CICS file control table to use and how to access the CICS VSAM file.
    6. Select the elements that you want to map to columns in your relational table.
    7. If you are creating a view, specify the criteria for the WHERE clause.
    When you finish the wizard, the new table appears under the selected schema. If you created a view, the view also appears under the selected schema.
  2. Optional: Select the table and, in the Properties view, modify any of its properties or add privileges.
  3. Optional: Create one or more indexes on the table. See Creating indexes.
  4. Optional: Generate the DDL for the table. You can generate the DDL later, if you do not want to generate it now. You can also generate the DDL for all of the objects within the same schema. See Generating DDL.
    1. Right-click the table and select Generate DDL.
    2. In the Generate DDL wizard, follow these steps:
      1. Choose to generate CREATE statements.
      2. Choose to generate DDL for tables. You can also choose to generate DDL for indexes.
      3. Name the file in which to save the DDL within your project.
      4. Choose whether to run the DDL on a data server. After you run the DDL, check the Data Output view to determine whether the DDL ran successfully.
      5. Choose whether you want to open the DDL for editing.
  5. Optional: If you ran the DDL successfully on a data server, validate the table by running a test query against your CICS VSAM file. Be sure that the data server is connected to the system where the file is located.
    1. In the Database Explorer, search your data server for the schema that you created the table in. Expand the schema and expand the Tables folder.
    2. Right-click the table and select Data > Sample Contents.
    3. Check the Data Output view to determine whether the test query ran successfully.
  6. Optional: If you created a view, generate the DDL for the view. You can generate the DDL later. You can also generate the DDL for all of the objects within the same schema. See Generating DDL.
    1. Right-click the view and select Generate DDL.
    2. In the Generate DDL wizard, follow these steps:
      1. Choose to generate CREATE and ALTER statements.
      2. Choose to generate DDL for views.
      3. Name the file in which you want to save the DDL within your project.
      4. Choose whether to run the DDL on a data server. After running the DDL, check the Data Output view to find out whether the DDL ran successfully.
      5. Choose whether you want to open the DDL for editing.
  7. Optional: If you ran the DDL successfully on a data server, validate the view by running a test query against your CICS VSAM file. Be sure that the data server is connected to the system where the file is located.
    1. In the Database Explorer, search your data server for the schema that you created the view in. Expand the schema and expand the Views folder.
    2. Right-click the view and select Data > Sample Contents.
    3. Check the Data Output view to whether the test query ran successfully.
