How to measure actual usage of BLSR buffers?

I did search the archives for this one, but I did not find any references. Is there some way to measure how many BLSR buffers (data and index) were actually used after a job has completed? For instance, if BUFND=2700,BUFNI=180 was specified in a SUBSYS=(BLSR,...) DD statement, how could I discove

ect: Re: How to measure actual usage of BLSR buffers? BLSR has no opportunity to provide any function like this. All that BLSR does is intercept the VSM NSR OPEN of a SUBSYS DD, do a BLDVRP to build an LSR buffer pool, CLOSE the SUBSYS DD, and then OPEN the real VSAM dataset using the LSR buffer poo

Re: How to measure actual usage of BLSR buffers?

to measure actual usage of BLSR buffers? Maybe there is a way to measuse. It's not acurate, actually it's quite vague but you can have an idea of consume. There is a IEFACTRT exit (present at cbttape in file 311) that builds several statistics, including storage above and below, I/O by

Re: How to measure actual usage of BLSR buffers?

Followup re: VSAM LSR statistics for the archive: It appears that VSAM LSR keeps certain statistics for each buffer pool from the time it is created to the time it is deleted. You can get the current values by using SHOWCB with an ACB that is already OPEN using LSR and that buffer pool. These ar
