To use a collision resolution other than the default *HLDERR, you must have the following:
-
The data group definition used for replication must specify a data group type of *ALL or *DB.
-
You must specify either *AUTOSYNC or the name of a collision resolution class for the Collision resolution element of the File entry option (FEOPT) parameter. Specify the value as follows:
-
If you want to implement collision resolution for all files processed by a data group, specify a value in the parameter within the data group definition.
-
If you want to implement collision resolution for only specific files, specify a value in the parameter within an individual data group file entry.
-
If you plan to use an exit program for collision resolution, you must first create a named collision resolution class. In the collision resolution class, specify *EXITPGM for each of the collision points that you want to be handled by the exit program and specify the name of the exit program.
