Reconfiguring a Network Services Server

Most network services servers ignore changes to configuration files while they are

running. The BIND 9 domain name server named can be reconfigured using the rndc

or nsupdate utility, as described in the DNS Configuration and Management Manual

and the nsupdate(8) and rndc(8) reference pages online.

Configuration files such as /etc/inetd.conf can be edited while the servers are

running. However, to make such configuration changes take effect, you must:

1. Warn your users. You can use a method similar to the one described under

Manually Stopping the OSS File System and the OSS Environment on page 2-3.

2. Stop or interrupt each process separately by identifying its OSS process ID (PID)

using the ps command from an OSS shell prompt and then issuing a kill

command.

For example, to interrupt the inetd process, enter commands similar to the

following:

kill -s SIGHUP 4291

where 4291 is the OSS process ID of the inetd process. This form of the kill

command sends the SIGHUP signal to the inetd process; inetd rereads its

current configuration file in response to this signal and continues to run using the

new configuration.

Removing a Server

How and when you remove a server depends on the type of server. You cannot

remove the OSS sockets local server, the OSS message-queue server, or an OSS

transport agent server.

•

Removing a Network Services Server on page 4-50

Other servers used by OSS applications require separate procedures. For more

information, see the manual appropriate for a specific server.

Removing an OSS Name Server

You remove an OSS name server by removing its entry in the Enscribe database

ZOSSSERV file.

1. Make sure that you are a member of the super group (255,nnn).

Note. You cannot remove the OSS name server for the root fileset, $ZPNS.
