>From the deep dark mists of time <G> IIRC, the tuning methodology is to issue D NET,BFRUSE at periodic intervals and adjust the settings in ATCSTRxx accordingly so that buffer expansion/contraction is minimal.
There were many tricks with the SNA definitions that have probably been committed to paper/redbooks/manuals in the past regarding the flow of data through the SNA network. Search IBM LINK with keywords VTAM, PERFORMANCE and you will most likely get several hits. Information apars IIxxxxx are especially helpful. Googleing with the same keywords turned up 47000 hits. HTH, <snip> Hello all, I was wondering if anyone new of a good manual that would help in tuning vtam buffers under z/os 1.7 I have looked at SC31-8777 and this gives some information, but I was wondering if there was a redbook(I have searched redbooks and couldn't find one) or some other paper available that explains it a little better. Any help appreciated. </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
