Hello: We discovered this new feature in the z/OS 1.7 migration. Searching information about it, we found following info:
Large Systems Update 2005 DFSMS 1.7 Highlights Catalog Autotuning Support �� Catalog performance is dependent on three parameters when defined o Number of strings o Number of data buffers o Number of index buffers �� Possible performance problems may exist when a catalog has heavy concurrent activity, have a high number of large (spanned records), or significant index size �� Autotuning support will adjust the data and index buffer numbers upward as demand for a catalog increases �� As activity increases for a catalog CAS will detect the activity and the number of strings will be increased �� If the values are increased they will be remembered if the catalog is closed and then referenced again o The actual catalog entry will not reflect the new values �� Message IEC391I will identify the new values �� Catalogs will be scanned every 10 minutes It will be possible to deactivate it? How to do? Chr.
