The different components of the interNet Services software package are installed as a POSIX program package by the POSIX installation program (see the manual “POSIX Basics for Users and System Administrators”). You will find more detailed information on the installation of the components in the section “Installation”.
For the installation and operation of the TCP-IP-SV component NTP, the PLAM library SINLIB.TCP-IP-SV.nnn.NTP must be shareable.
| Install NTP under the TSOS ID with the POSIX installation command because privileged actions also need to be executed:
| |
| Select the following for installation / specify the following: | |
Function1: IMON support ? name of product package of product | Install packages on POSIX Y TCP-IP-SV NTP | |
... 1version of product is determined by the highest version in IMON. | ||
| You can change the installation path which is displayed as the procedure continues. However, you are recommended to retain the default /opt/TCP-IP-SV/ntp as all path names in this document are based on this default setting. The POSIX installation program then checks that the /opt file system has sufficient storage space and inquires whether the NTP daemon should later be started automatically each time POSIX starts. | |
| If you change the default setting "no" to "yes", you can undo this decision later by editing the /etc/default/TCP-IP-SV.ntp file (AUTOSTART variable). After you have answered the question, the files from the PLAM library are imported to the POSIX file system. | |
Any further activities required after successful installation are carried out in the POSIX shell under a user ID with POSIX root authorization. The POSIX shell is started with the BS2000 START-POSIX-SHELL command for this purpose. The relevant commands and files are in the /etc and /var directories and the installation directory /opt/TCP-IP-SV/ntp. In the table below <instdir> stands for the installation directory /opt/TCP-IP-SV/ntp.

After installing the NTP interNet Service and before starting the NTP daemon, the NTP configuration file of the individual components must be customized to individual requirements (see "Creating the NTP daemon ntpd configuration file"). However, this is only necessary if no backup of the NTP configuration file from a previous installation could be restored.
If the POSIX subsystem is stopped and then restarted, the interNet Services daemons activated after installation are also started automatically.
