Is there any Datacom documentation available about Data Sharing? 

z/OS, CA Datacom/DB 14.0 and higher

Please read Chapter 15: Parallel Sysplex, Data Sharing (MUFplex) 

in the CA Datacom Database and System Administration Guide for version 14.0 or read online here 


You can setup a MUFPLEX with one or more MUFs using full data sharing.

You do this by coding the mode parameter in the MUFPLEX startup option as either A or B instead of S for Shadow MUF. 

The MUFs need to share the same CXX,LXX and FXX datasets but each MUF must have its own PXX dataset. 

and review these techdocs : 


- TEC264411 Data Sharing - Using MUFPLEX in a Z/OS Sysplex 


- TEC496302 Does CA Datacom support the dynamic growth or rebuild of its MUFPLEX list and lock Coupling Facility structures? 


- TEC605254 CALCSIZE utility gets a S0C1 abend and returns ERROR IN IXLCSP MACRO NEED R0 R15 message. 


There is a video and pdf that describes the use of MUFPLEX - CA Datacom Tuning 109: Continuous Availability
