Open System Services Management and Operations Guide (G06.30+, H06.08+, J06.03+)

Example 7 Configuring FILESET INODES in SCF
> ASSUME $ZPMON
> ALTER FILESET ROOT, MAXINODES 650000
> CONTROL FILESET ROOT, SYNC
NOTE: The inodes (MAXINODES) limit cannot be set to less than the current usage. A warning
limit EMS event is generated when the resource reaches the warning threshold. A limit error EMS
event is generated when 100% is reached.
The OSS Server Process (OSP) Servers
The OSS server process (OSP) server manages resources for thread-aware file I/O operations on
OSS regular files without blocking threaded client applications from running other threads. The
OSP server also allows those shared OSS resources to be released without requiring involvement
of the client application when thread-aware I/O operations complete.
An OSP server named $ZSPnn runs in each processor (nn indicates the processor number). The
OSP server starts automatically when the processor starts; if the $ZSPnn process terminates
abnormally, it takes down the processor in which it runs. The OSP program file, OSSSP, is a
standard component of a SYSnn subvolume. There are no management tasks associated with OSP
servers. You cannot start and stop OSP servers using the OSS Monitor SCF START SERVER command
and STOP SERVER command. You cannot add, modify, or remove an OSP server.
NOTE: OSP servers are supported on systems running J06.04 and later J-series RVUs and H06.15
and later H-series RVUs only.
The Terminal Helper Servers
There is one terminal helper server process (used for OSS nonblocking terminal input and output)
for each processor in your system. The terminal helper server provides support for application use
of the select() function and the FILE_COMPLETE_ family of procedure calls on terminal device
files to provide nonblocking terminal input/output.
The process name is $ZTTnn, where nn is the processor number. Each terminal helper process
server is automatically started when the processor it runs on is started.
You cannot start and stop the OSS terminal helper servers using the OSS Monitor SCF START
SERVER command and STOP SERVER command. You cannot add, modify, or remove an OSS
terminal helper server.
The Network Services Servers and Tools
The following subsections briefly discuss:
• “inetd” (page 98)
• “rshd” (page 99)
• “rexecd” (page 99)
• “portmap and RPCINFO” (page 99)
• “BIND 9 Domain Name Server and Tools” (page 99)
All but RPCINFO are usually demon processes or processes started by demon processes on UNIX
systems.
inetd
The inetd process is the UNIX and OSS equivalent of the Guardian LISTNER process for AF_INET
and AF_INET6 OSS sockets applications. In the OSS environment, inetd is the server process
that listens for network activity.
