Can you cache the library in VLF (not LLA) without changes to the applications that uses the library?

But in case something was introduced in the last few years, is there a facility that would cache in memory a library (PDS/PDSE), directory and members? This would be a library NOT covered by the COFVLFxx Classes. Looking at DASD statistics for our BMC CTx product libraries, I see that the CTx parmlib dataset gets hundreds of thousands of batch job hits, with millions of I/O to the library. The DASD controller cache hit percent is 97. But the best and fastest I/O is no I/O. Did Batch LSR support libraries and does anyone still use BLSR? "Confidentially doc, I am the wabbit."
