How about Batch LSR (BLSR) or HIPERBAT ??
<snip> We have a CICS application that is doing upwards of 2000 I/O's per second to a single VSAM file. The entire CICS region is using 4.5% of a z/990 2084-309. The CICS buffer hit ratio is around 60%, after we doubled the number of buffers (can't do that too many times). The cache hit ratio is over 98%. We have run out of all tuning options, save one. Replace or remove the application. </snip> ---------------------------------------------------------------------- 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
