Setting the Cache Entry Version Number

z/OS MVS Programming: Sysplex Services Guide
SA23-1400-00

The WRITE_DATA request allows you to set up or change the version number of the target data entry by specifying the VERSUPDATE parameter. The version number can be:
  • Assigned a particular value (VERSUPDATE=SET,NEWVERS=newvers)
  • Incremented by one (VERSUPDATE=INC)
  • Decremented by one (VERSUPDATE=DEC).
Note: When a data entry is created, its version number is set to zero. If you specify VERSUPDATE=INC or VERSUPDATE=DEC when you create a new cache entry, the system uses zero as the value to be incremented or decremented.
