Hi,

What is the significance of share option while defining a VSAM file.
And what is the difference between the share option (1 3) and (3 3).How can it affect the usage of a VSAM file.

Thanks,
Raman

Hi There,

SHAREOPTIONS(crossregion,crossystem)
SHAREOPTIONS(1,x): One user can have the dataset open for read/write access or any number of user for read only
SHAREOPTIONS(3,x): Any number of user can have the dataset open for both, read & write access .

The share options of a VSAM data set are specified as a parameter for an IDCAMS DEFINE CLUSTER that creates a new data set. They show how a component or cluster can be shared among users.

Hope it will helpful
