To pick up on one point, HBUFNI/D are for hiperspace buffers. These are still valid and are NOT in the address space's own range, but rather in hiperspaces. Hiperspaces are backed by central storage now.

Sent by: IBM Mainframe Discussion List <[email protected]> I believe that I saw a statement here recently that at least QSAM buffers can now be allocated above the 4G bar in 64-bit address space, but I cannot find the email in which that statement appeared. Is this a true statement, and if so can someone point me to doc that shows how and where to specify it? Is VSAM eligible to have buffers above the 4G bar? If so, same request: please point me to the doc on how and where it can be done. Lastly, if any of this is true, can SMB and/or BLSR support LSR buffers above the 4G bar? I'm thinking particularly of the BLSR parameters HBUFND and HBUFNI: are they allocated above the 4G bar? Those parameters originally specified buffers in expanded storage, which is no longer available, right? TIA for curing my ignorance on this subject.
