Configuration Files Used for the OSS Name Servers
If your system has been upgraded from a G05.00 or later RVU, the OSS Monitor
automatically creates an initial ZOSSFSET file containing the information from the
older system’s ZPOSFSET file.
If your system has been upgraded from an RVU preceding G05.00, the OSS Monitor
automatically creates an initial ZOSSFSET file containing the information from the
older system’s ZPCONFIG and ZPMNTTAB files.
If your system is upgraded to a G06.24 or later RVU, the initial MAXINODES value is
zero; the OSS Monitor changes that value to a more appropriate one as soon as the
fileset is started.
If your system is upgraded to a G06.17 or later RVU, the OSS Monitor automatically
upgrades an existing ZOSSFSET file and creates a backup copy of your original file in
$SYSTEM.ZXOSSMON.ZOLDFSET.
Figure 4-2 on page 4-12 shows how the entries in the ZOSSFSET file correspond to
disk files, disk volumes, and other attributes in the following list:
The files $DATA2.ZYQ00000.Z0000435 and $DATA1.ZYQ00000.Z0000011 represent
OSS data files located in the example root fileset (ROOT) illustrated in the figure.

1 Beginning with RVU G06.15.
2 Beginning with RVU G06.17.
3 Beginning with RVU G06.17 and until RVU G06.18, the default was -1 (same processor as OSS Monitor).
4 Beginning with RVU G06.24. However, if the fileset was created using an earlier RVU, 0 is used as the initial
default to force use of a value adequate for the existing number of inodes when the fileset is next started:
•
If 110% of the in-use inodes is less than or equal to 500,000, the MAXINODES value is reset to 500,000
when the fileset is restarted.
•
If 110% of the in-use inodes is greater than 500,000, the MAXINODES value is reset to the minimum of
2,200,000 and 110% of the number of in-use inodes rounded up to the nearest thousand when the
fileset is restarted.
5 Beginning with RVU G06.27. However, if the fileset was created using an earlier RVU, the default behavior
depends on the setting of the disks’ OSSCACHING attribute in the storage management subsystem.
