Default: MAXBUFSP=128K
The MAXBUFSP constraint specifies the maximum amount of virtual storage that dynamic buffering can use to create buffers for a file. The sum of (data CI size * bufnd) + (index CI size * bufni) does not exceed this value for any particular OPEN, unless MAXBUFSP is not at least equal to ((1+strno) * (data CI size)) plus ((strno) * (index CI size)). You specify MAXBUFSP as:
MAXBUFSP=value
Value is validated by the CA Hyper-Buf OPEN intercept routine and must be at least as large as the VSAM calculated minimum allowable buffer space. If the specified value is smaller, CA Hyper-Buf increases your specified value to the VSAM minimum.
If you do not provide any MAXBUFSP value for a particular LEVEL selector, the SYSTEM default value is used.
