Good morning, we are working in catalog performance and we have read some post, zOS DFSMS-Managing Catalogs and Cheryl Watson Tuning Letter 2001 - N1. About following paragraph: "BUFND Specifies the number of buffers for transmitting data between virtual and auxiliary storage. The default, STRNO+1, is usually adequate. When a catalog contains large GDGs or other spanned records, the number should be increased accordingly to a minimum of MAXLRECL/CISIZE+STRNO." before to try and error, we would like to know experiences about usercatalogs with "large" GDGs and which will be, orientative, the amount of GDGs to consider 2nd suggested rule? Thanks
