Using IMS enhanced dump analysis

You use the IMS Enhanced Dump formatting menu to browse and select formatting options for database, Fast Path, Transaction Manager and System dumps. There is also a tutorial available about the formatter and how to use the filtering tool.

Procedure

  1. Select option E from the IMS dump formatting primary menu.
    The IMS Enhanced Dump Formatting Menu displays, as shown in the following figure.

    Enter  END  or  RETURN  command to terminate IMS component

    In this panel, the control blocks are organized by function for ease of use. For example, EPST (the extended partition specification table) is located under option 3 for Fast Path.

  2. To review tutorial information about the formatter and about how to use the filtering tool, type T and press Enter.
  3. To use a filtering tool to identify filtering criteria, type on of the options 2, 3, 4, or 5 and press Enter.

    An example of a filtering panel is shown in the following figure.

     ------------------ Generic Filtering Panel ---------------------                                                                                 
    Explanation of the fields:                                                     
        Offset  (required)     - Offset of the field in the block.                  
                                 (hex)                                              
        Length  (default = 1)  - Length of field in the control                     
                                 block. (decimal)                                   
        Cond    (default = EQ) - Type of compare to be done. (EQ,NE,                
                                 GT,GE,LT,LE)                                       
        Bit     (default = N)  - Should comparison be a bit mask?                   
                                 (Y or N)                                           
        Type    (default = X)  - Is the value type decimal, hex, or                 
                                 char (D,X,A)?                                      
        Value   (required)     - Value of the field to be compared                  
                                 at given offset.                                   
        Qual                   - Qualify filter to search in                        
                                 sub-blocks.                                        
        AND/OR                 - How to combine multiple conditions.                
                                 If blank, only the first condition                 
                                 will be executed.
                                           (up to four conditions allowed).                                 
  4. You can overwrite the generic filtering panel default values. For example, you can select criteria that presents two separate conditions. By selecting AND you indicate that both conditions must be true
    1. You want all the blocks starting at OFFSET 1C that have a value of X'08.'
    2. You want all the blocks starting at OFFSET A4 that have a non-zero value.

    These values are shown in the following figure.
