Issue/Introduction

An SE37-04 abend on package ship was received. A check was done  on the DSN Mapping Rule for the dataset and it does not appear to be working. 

The value in the field "Approx Host Members/Cyl" looks like it is picking up the default of 16 members per CYL.

 

Environment

Release :

Component : CA Endevor Software Change Manager

Cause

If a dataset not excluded and is not found to match any DSN MAPPING dataset, then the default will be used.

The default will have Approx Host Members/Cyl=16 and the dataset will map to it's self. So mapping to the remote LPAR with the same DSN as the host.

Resolution

This is how DSN Mapping Rule selection works. 

1)The dataset is compared to the excludes.  If it find a match the dataset is excluded from selection.

2)The dataset is compared  DSN Mapping Rules if it find a match that DSM Mapping rule is used.

3)The default will be used. This being Approx Host Members/Cyl=16 and the dataset will map to it's self.

It is recommended that you use option T - Test DSN Mapping Rules . This will give you a indication what  or if a rule is being selected.

Additional Information

Examples:

1)

HOST DATASET NAME ===> *.*

If the dataset is BST.PROD.LOADLIB then the above mapping will not be selected.

2)

HOST DATASET NAME ===> *.* .*

If the dataset is BST.PROD.LOADLIB then the above mapping will be selected.

3)

HOST DATASET NAME ===> *.* .LOADLIB

If the dataset is BST.PROD.LOADLIB then the above mapping will be selected.
