Using Enhanced Catalog Sharing Mode z/OS DFSMS Managing Catalogs SC23-6853-00 |
|
ECS mode provides a substantial performance benefit for catalogs that are shared between one or more systems in a sysplex. To use ECS mode, you must include the ECS structure in the Coupling Facility Resource Manager (CFRM) policy. You must also define (or alter) one or more catalogs to set the ECSHARING attribute. |
