NFS Server SMF records In z/OS V1R12, NFS allows you to specify that SMF records be created when a file system object is created, renamed, or removed. New SMF42 subtype 26 records can be specified with a new site attribute or enabled by operator commands for both z/OS UNIX file objects including directories and files, and data sets and members. In conjunction with z/OS UNIX Type 80 and RACF Type 92 records, this support is intended to improve auditability for NFS file operations. NFS Server cache monitoring and reporting In z/OS V1R12, the NFS Server performs additional cache monitoring and reporting. The NFS Server issues warning messages when the value specified for the bufhigh site setting is being approached, and issues additional messages when a buffer shortage or impending buffer shortage has been relieved. This is intended to allow you to use automation to respond to impending buffer shortage events. NFS Server displays accounting statistics NFS Client displays the statistics about the NFS Client activities to the z/OS NFS Server. The displayed statistics include the number of NFS V2, NFS V3 and NFS V4 operations being used by the NFS Clients in their communication with the z/OS NFS. NFS password phrase support for the MVSlogin client utility In z/OS V1R12, the NFS Server supports password phrases up to 100 characters in length for mvslogin, in addition to existing support for passwords up to 8 characters long. This support will require password phrase support from an external security manager such as RACF. This is intended to allow you to migrate to password phrases, which offer a much larger name space than passwords.
