The computer name of the host that you are adding must contain only the following characters: a-z, A-Z, 0-9, minus sign (-),
period (.), and underscore (_). A host is named according to the computer that it runs on.
Firewalls on the host must allow TCP/IP connections.
On each host you add to the cloud, the firewall must be configured to allow TCP/IP connections to the TCP/IP, HTTP, and HTTPS
ports used by each cloud server installed on the host. Similarly, any firewalls on or between a host that is used to connect
to any cloud server must be configured to allow TCP/IP connections to the TCP/IP, HTTP, and HTTPS ports used by the cloud
server. Connections fail and the cloud might not operate correctly if firewalls are not configured properly.
If your firewall blocks incoming connections by application, configure your firewall to allow connections to the dbsrv16 executable.
Additionally, if your firewall blocks outgoing connections by application, you must configure your firewall to allow outgoing
connections from all cloud executables.
When you add a host, you can assign the host a range of cloud server ports for each of the TCP/IP (Command Sequence and TDS),
HTTP, and HTTPS protocols. By default, cloud servers that start on the host use ports from these port ranges. You can change
the port ranges that are assigned by the cloud to new hosts, as well as the port ranges of a host.
When you install the cloud or add a host to the cloud, you specify the location for the data directory. All database copies
are stored in this directory. If the location of your data directory is not local storage, ensure that minimum I/O requirements
are met. See:
Install Adobe Flash on any cloud host where cloud administration is performed. The Cloud Console, the main user interface
for administering the cloud, requires Adobe Flash. See Cloud Console requires Adobe Flash
When you create a host install for the cloud, you must create either a single use install or a multiple use install.
Specify Single use if you have one computer that you want to turn into a cloud host. Single use host installs are not available for use once
they have been used. When you choose Single use, specify the name of the computer for the host name. This installer can only be run on the computer whose host name matches
the host name that you specified.
Specify Multiple use if you have several (homogeneous) computers that you want to add as hosts, or if you expect to run the host install multiple
times. You can restrict the computers that a multiple use host install runs on to a specified list of IP addresses. When you
are prompted to specify where the installer can run, choose Restricted and specify the IP addresses.
