Security password to authenticate data requests between the database server and the other servers3
1The virtual hostname and virtual IP (VIP) address are shared by both the primary and secondary database servers.
2IMM = integrated management module. The IMM configuration is required to provide active/standby redundancy on the database servers. For the call engine and administration servers, you need to configure the IMM only if you want remote control.
3The security password must be identical for all nodes in the server cluster. After you set the security password on a server, you cannot change it without reinstalling the server.
