The following explains how to define hosts in the "hosts" file.
Outline
Before using a Systemwalker Operation Manager's client, you must define the host name and IP address of the connected server machine in the "hosts" file stored on the client machine.
To use the Systemwalker Operation Manager Web Console, the host names and IP addresses of the hosts being monitored must be defined in the "hosts" file for the environment where the Web server is running.
In operations where network jobs are operated between servers, it is necessary to ensure that the IP address of the schedule server can be resolved from its host name. For this reason, register the host name and IP address of the schedule server machine in the "hosts" file on the execution server.
To use a Systemwalker Operation Manager server in an IPv4/IPv6 dual stack environment, define both the IPv4 and IPv6 addresses corresponding to the host name of the local host in the "hosts" file on the server.
Definition procedures
Edit the "hosts" file locating under the "<System root>\system32\drivers\etc" directory or the "etc" directory by using an editor, such as Notepad.
Note
/etc/hosts setting (Linux/Solaris versions)
With the default of the Red Hat type Linux or Solaris 11 or later, "127.0.0.1" is set in the /etc/hosts file as the IP address of the hostname of the local host. This can lead to the following issues:
If a Systemwalker Operation Manager client or multi-server monitoring client is connected, it may not be possible to correctly monitor a server with this setting.
If a network job is executed for another server from this server, it will take longer than expected to execute network jobs.
If a network job is executed for another server from this server, the network job may end abnormally.
Therefore, the IP address for the host name of localhost configured in the /etc/hosts file during installation must be an address that can be connected from the client and from the execution server.
An example of /etc/hosts file settings is shown below:
[Before]
127.0.0.1 <host name> localhost[After]
127.0.0.1 localhost
xxx.xxx.xxx.xxx <host name>Note: xxx.xxx.xxx.xxx is the IP address for <host name> (localhost).Notes
Systemwalker Operation Manager can run in an environment where a WINS server is used.
If you have used the DHCP server to dynamically assign an IP address to the server machine, you cannot start the Systemwalker Operation Manager's server functions. Make sure that the DHCP is not used. However, you can use the Systemwalker Operation Manager's client functions even in the environment where the DHCP server is used.
