Attributes data set

The attributes data set contains the settings for the z/OS NFS server. There are three types of attributes stored in this data set:

Data set creation attributes: Used to define the structure of MVS™ data sets when creating a file (for z/OS conventional MVS data sets only).
File processing attributes: Used to control how files are accessed by the client.
Site attributes: Used to control z/OS NFS server resources.

The system administrator changes the default settings by editing the attributes data set and restarting the server. Client users can override the data set creation and file processing attributes at the command line. For z/OS conventional MVS data sets, the client user can specify the data set creation attributes when mounting, creating, or accessing files. The client user can override the file processing attributes when mounting, creating, or accessing files. However, some file processing attributes can only be overridden on a mount point basis.

Note: Many of the attributes are valid only for z/OS conventional MVS files, and not for z/OS UNIX files. Attributes used for z/OS UNIX file access gives a complete list of attributes that are valid for z/OS UNIX.
