I can't answer your question about catalog searches, but if you're looking to increase your hit ratio, perhaps you should look at your MAXVIRT setting in COFVLFxx.
Here's some advice from Greg Dyck on the subject: http://bama.ua.edu/cgi-bin/wa?A2=ind0201&L=ibm-main&P=R97369&D=0&I=1&O=D HTH, Greg Shirey Ben E. Keith Company -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] Behalf Of Ron van der Zande Sent: Thursday, March 30, 2006 4:02 AM currently we encounter high I/O activity on some of our ICF catalogs. These catalog's are on dedicated volumes, all under VLF and the F CATALOG,REPORT,CACHE shows HIT% above 70%. (Coupling facility usage not possible due to SYSPLEXES sharing) Tthe create, update and delete activity I can figure out using the SMF records produced. Question: How to diagnose the searches issued against catalogs? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
