them when necessary. If you do not select Manage OSS Files, NonStop Software Essentials
or DSM/SCM just installs the files needed to set up the OSS environment into the TSV.
• The TACL COPYOSS macro, which automatically runs the Guardian PINSTALL utility on all
the archive files in the subvolume.
• The PINSTALL utility, which you can run manually for individual archive files.
The use of either COPYOSS or PINSTALL also requires you to use the OSS Pcleanup utility to
remove obsolete files. NonStop Software Essentials and DSM/SCM do not require Pcleanup.
See “Removing Obsolete OSS Files and Directories” (page 181) for more information.
The considerations for these options differ slightly, as shown in Table 13.

Using COPYOSS
COPYOSS can be used to load the contents of a single pax archive file into the OSS file system
or to load the contents of all the pax archive files in a subvolume. When COPYOSS is used on
the entire contents of a subvolume, it processes all files in the subvolume with file codes of 0 or
180 unless the files have file identifiers beginning with ZFB or ZPG; files with file identifiers
beginning with ZFB or ZPG are assumed to be old files renamed by NonStop Software Essentials
or DSM/SCM and are ignored.
