I am interested in determining/clarifying what the current market share
breakdown is for EACH of the three z/OS ESM products: RACF, CA-ACF2 and CA-Top
Secret. In his 5/24/12 interview with Jeffrey R. Yost, Ph.D.
(conservancy.umn.edu/bitstream/handle/11299/132470/oh404bs.pdf), Barry Schrager
noted that:
(a) When SKK was sold in 1986, ACF2 had a 60% market share while IBM’s RACF and
CA’s Top Secret split the other 40%; and (b) Currently , RACF has 75% market
share while ACF2 and Top Secret from CA share the other 25 percent.
Thanks in advance for any further information which you can provide regarding
what the current market share breakdown is for EACH of the three noted z/OS ESM
products.

I would take Barry's word as gospel. Just based on what I've seen at my
clients, I would tend to agree with his numbers.
