CSM controls every data access to remote devices (disk/tapes) and executes them synchronously.
As a result there a new ways to access data that didn’t exist before , especially over CPU-bounbaries.
CSM works synchrounously, wich means that every event, that can occurr while accessing data (e.g D37,S013 ,S91) is treated like it is know to the system the job is running on.
Naturrally this includes remote security checks wich validate if and how data is allowed to be accessed.
No check-ups and waiting periods necessary to see results
Simplification and protection of complex production processes without complex asynchronous receipts
In contrast to asynchronous data processing, results can be reacted upon immediately
No product specific programming language Easy integration into existing procedures
No training necessary
Easy to understand and detailed error messages
One additional copy step to be omitted
High level of automation
Improved quality of software maintenance
Just one logon necessary
Good overview of disks
Takes care of access rights regardless of the security system in use
No additional utilities necessary
An additional utility-step is obsolete
Saving of dasd space
Easy to maintain, since utilities are kept current by z/OS
Saves money for hardware and “shared tape“- software solutions
Keeps recovery-environment current
No sequential data processing necessary
Version- / Release-updates across sysplex boundaries
Central system control and system management
