Hi,
Even if I give DISP=SHR option to a data set it is allowing to copy data to that dataset i.e. it is allowing to edit. DISP=OLD will give X lock and rewrites the data and DISP=SHR appends the data and DISP=SHR is allowed to read this is what i know sofar. But just executed one jcl which is having DISP=SHR and still it is allowing to copy data to it. Pls. clarify what is DISP=SHR is.
SHR
Indicates that the data set exists before this step and that other jobs can share
it, that is, use it at the same time. This subparameter can also be coded as
SHARE.
If you specify DISP=SHR for an output tape data set and (1) the data set is not
protected by RACF or a password or (2) the data set has no expiration date,
the system does not verify the data set name in the header label.

DISP=SHR and DISP=OLD only control whether other users may access the file at the same time. Neither one will control update access to the file. You would use your security product for this. _________________ Regards,
