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

4 Managing Servers
This chapter describes how to manage the servers used to provide the Open System Services (OSS)
environment. Not all servers are managed through the same interface; read the subsections
“Introducing the OSS Servers” (page 90) and “Configuration Files” (page 100) before attempting
any operation on an OSS server.
The introductory information in this chapter helps you perform the following operations:
• “Adding a Server” (page 120)
• “Configuring a Server” (page 121)
• “Starting a Server” (page 127)
• “Obtaining Information About a Server” (page 130)
• “Stopping a Server” (page 133)
• “Reconfiguring a Server” (page 135)
• “Removing a Server” (page 138)
• “Troubleshooting a Server” (page 139)
Procedures in this chapter are representative. Normal practices at your site might require additional
steps or use of additional command parameters for logging purposes.
Introducing the OSS Servers
A UNIX system depends on the operation of many demon processes that provide services as servers.
Similarly, the OSS environment is created by servers, depends on other servers running in the
Guardian environment, and runs servers within itself.
The servers that create the OSS environment were introduced in “Components to Be Managed”
(page 33). These servers are further described in the following subsections:
• “The OSS Name Servers” (page 92)
• “The OSS Message-Queue Server” (page 92)
• “The OSS Sockets Local Servers” (page 93)
• “The OSS Transport-Agent Servers” (page 93)
• “The OSS Resource Agent Servers” (page 93)
These servers are all managed using OSS Monitor SCF commands. All SCF commands for servers,
except INFO SERVER and STATUS SERVER, can be run only by a member of the super group
(255,nnn).
See the following SCF commands for information about the OSS servers resources:
• For descriptions of the OSS name server and OSS message-queue server resources, and how
to specify resource values, see “ALTER SERVER Command” (page 278).
• For information about displaying the currently configured resource values for any of the OSS
servers, see “INFO SERVER Command” (page 301).
Other servers that run in the OSS environment are not managed through OSS Monitor SCF
commands. Such servers include:
• OSS server process (OSP) helper server processes, as described in “The OSS Server Process
(OSP) Servers” (page 98).
• OSS terminal helper server processes, as described in “The Terminal Helper Servers” (page 98).
• Network services servers such as inetd, rshd, rexecd, and named, as discussed in “The
Network Services Servers and Tools” (page 98).
