Introduction to ICF Catalog Tuning Techniques

Project and Program: MVS, MVS Storage Management

Tags: Proceedings , SHARE Atlanta 2016 , 2016

The primary consideration when defining ICF catalogs is recoverability.  After that has been addressed you can take a look at performance.  The BCS is a VSAM KSDS and is tuned in a very similar manner to any other KSDS.  As with most data set tuning, a major facet of improving performance is to speed up, reduce or eliminate I/O.  The speakers will discuss several tuning techniques including monitoring the catalog address space, caching of catalog records, Enhanced Catalog Sharing and RLS for catalogs.  Remember the role of a catalog is to locate your data.  You can help ensure that it does its job efficiently.-Janet Sun-Rocket Software, Inc.; Stephen Branch-IBM Corporation
