An instance of the ALL OPENS resource represents the concept of a UNIX open on a PIPEFIFO OPEN, AF_INET SOCKET
OPEN, AF_UNIX SOCKET OPEN, TTY OPEN, DISK OPEN, NFS OPEN, DIR OPEN, or DIR STREAM.
2
The terminal open limit is not necessarily on unique terminals; therefore, 32,000 opens on the same terminal or 32,000
opens on 32,000 different terminals are at this limit.
Table 9 lists the unbounded resources of the OSS File System and their per-processor soft limits.
These resources are viewable in both SCF and the HP NonStop Measure performance monitor.

This unbounded resource can exceed its soft limit if the ALL OPENS limit of 128,000 has not been reached or memory
pool resource limits have not been reached.

The NFS OPENS resource can exceed its soft limit if memory pool resource limits have not been reached.
Using SCF to View OSS File System Resources
The OSS resource agent server provides OSS FS resource usages and limits information to the
OSS Monitor, and you can use the Subsystem Control Facility (SCF) to view this information. (SCF
is the online configuration and management facility for H-series and J-series RVUs.)
The SCF STATUS SERVER command provides current and peak usage information for selected
OSS FS resources for one or more resource agent servers. The syntax for the SCF STATUS SERVER
command is:
STATUS [ /OUT filename/ ] SERVER server_processname
[ , DETAIL [ , param ]]
[ , SEL [ NOT ] state ]
The server_processname field is specified as $ZPMON.#ZRAnn, where nn is the processor
number for the resource agent server. The processor number for the resource agent server can be
wild carded to get information for all of the resource agent servers running in the system.
