Hi,

Can anyone point me to a document which explains the advantages/disadvantages of using BLSR?

Please share if you have any personal experience on the same.

Thanks in advance.

BLSR is exceptionally bad for sequentially accessing a VSAM file. It is designed for random access. Manual GC28-1469, MVS Batch Local Shared Resources, would be a good place to start learning about BLSR.
