PARMLIB updates

Add the data set defined in the GFSCPROC STEPLIB containing the z/OS NFS client library to the system's APF authorization list (IEAAPFxx). A sample cataloged procedure named GFSCPROC is provided as a member of the sample library NFSSAMP, see Sample z/OS NFS client startup procedures.

Add the filesystype parmlib statement shown in Figure 1 to the z/OS UNIX parmlib member (BPXPRMxx):

Figure 1. Sample filesystype parmlib statement

FILESYSTYPE
   TYPE(NFS)
   ENTRYPOINT(GFSCINIT)
   PARM('installation parms')
   ASNAME(proc_name)

The name in the TYPE operand must be NFS, otherwise the utility program nfsstat fails.

The operand ENTRYPOINT(GFSCINIT) specifies the entry point for the z/OS NFS client initialization.

The operand PARM('installation parms') specifies the installation parameters for the z/OS NFS client. See Table 2 in Mount processing parameters and installation parameters for a list of valid installation parameters.

The operand ASNAME(proc_name) specifies the procedure name in SYS1.PROCLIB that is used by z/OS UNIX to start the address space in which the z/OS NFS client is initialized.

Note: The proc_name is also used for the name of the address space.

For data integrity and data isolation among different PFSs, the z/OS NFS client is required to start in a separate and standalone colony address space. To start the NFS client in a separate and standalone colony address space, a unique proc_name must be used.
