    For information on restarting in Zend Server, see Server Restart.

For information on configuring the component daemon directives, see Configuring Component Daemon Directives (Zend Session Clustering, Zend Deployment, Zend Java Bridge, Zend Job Queue, and Zend Monitor).


If your server is behind a firewall, ensure your broadcast ports are open so that your servers can broadcast to each other. The port that should be opened is defined in the directive in your 'scd.ini' file. The default port number is 10060.

All servers in the cluster should be in the same subnet / broadcast domain.

Net Masks

Net Masks are used to define a string of IP addresses using Wildcards '*' to specify the range of IPs that are either allowed or denied hosts. This option, allows to specify a range of IPs from 0-255 according to the selected amount of Wildcards for example if you choose to use the Net Mask option to grant communication to the following IPs: 24 (10.1.3. *) all IP addresses beginning with 10.1.3 will be granted access to the Session Clustering Daemon on this server.
