Choosing configuration data sets

This article leads you through the "Allocate target data sets" option in the Customization Dialog.

Before you begin

You must start the Customization Dialog and select the "Create an empty managed node and add it to an existing Network Deployment cell" option.

About this task

Each option in the Customization Dialog saves customization jobs and files in a pair of customization data sets. While is it possible to reuse these data sets, it is safest to create separate data sets for each WebSphere Application Server for z/OS configuration. The best practice is to use the customization data set name prefix (sometimes referred to as "config_hlq") to indicate the version and release of WebSphere Application Server for z/OS, the task you are performing, and the cell (and, in some cases, the node name) you are configuring. For example, you might use the following data set name prefix for configuring a WebSphere Application Server for z/OS managed node named MA6N01 for cell MAINT1:

JULIA.WASV6R2.MAINT1.MA6N01.MANAGED

Complete this task before generating the customization jobs and files.

Procedure

  1. On the main dialog panel, type the appropriate number in the Option field to select "Allocate target data sets".
  2. Press Enter. Result: You see a panel that looks similar to the following:
    -----------------     WebSphere Application Server for z/OS Customization      ------------------
    Option  ===>                                                                  
                                                                                  
     Allocate Target Data Sets                                                    
                                                                                  
     Specify a high level qualifier (HLQ) and press Enter to allocate the         
     data sets to contain the generated jobs and instructions. You can            
     specify multiple qualifiers (up to 39 characters).                           
                                                                                  
     High level qualifier:                                         .CNTL          
                                                                   .DATA          
                                                                                  
     The Dialog will display data set allocation panels. You can make
     changes to the default allocations, however you should not change            
     the DCB characteristics of the data sets.                                    
                                                                                  
        .CNTL  - a PDS with fixed block 80-byte records to                        
                 contain customization jobs.                                      
                                                                                  
        .DATA  - a PDS with variable length data to contain                       
                 other data produced by the Customization Dialog.                 
  3. Fill in your chosen configuration data set name prefix value (config_hlq). If the data sets config_hlq.CNTL and config_hlq.DATA do not exist, you will be prompted for data set allocation information. If the data sets already exist, a message will inform you that they will be reused.

Results

The data sets config_hlq.CNTL and config_hlq.DATA are allocated and will store customization jobs and files. These data set names will also be saved along with the customization variables.
