After a gap of 10 years, I will be again working with DB2 on mainframe.
Is there any good book on S/390 or z/os, that adresses the components
of mainframes i-e RACF, ACF2 , data sharing, parallel sysplex ,attachment
facilities etc.
The mainframe manuals are always overwhelming. I prefer a hard copy
and specific about OS, no need about DB2
