Hardware Sizing

For a simplex (single server) deployment, minimum and recommended hardware requirements are as following:

vCPU2 Cores4 Cores
vDisk20 GB160 GB

For a redundant deployment, two servers of the same specifications (as mentioned above) are needed.

Software Requirement

Microsoft Windows Server 2012 standard Edition x64 R2

A Windows Server 2012 R2 64-bit or above is recommended

Locale Settings

English (recommended)

Java Runtime (64 bit)

Java Runtime (JRE) 8 is required

AntivirusAny of the antivirus as mentioned in Software License Requirements
WinRARA package extractor to modify embedded configuration properties

.Net Framework

.Net Framework 4.5.2 for Service Manager

Browser Requirement

Port Utilization

Following ports should remain open on the Firewall. The local security policy and any antivirus should also allow open communication on the following ports:

TypeSource HostSource PortDestination HostDestination Port

  • <Client Application> is a machine running client application of EF Connector. For server based applications like Siebel, it’s Siebel Communication Server. For desktop based applications, it’s the machine address of the agent desktop running the desktop application.
  • In a redundant deployment, both EF Connector instances communicate with each other on the same TCP OpenWIre port 61616. In the table above, it’s mentioned as EF Connector (B) ⇒ EF Connector. 
  • These are defaults set in EF Connector, but you can always change the default configuration.

If you need to file sharing and remote installation / configuration using RDP, you might need to open the following additional ports:

System Access Requirements

  • Administrative access (LocalSystem account or domain administrator) on the Connector Server is required to do the installation and configuration.

Time Synchronization Requirements

An important consideration is time synchronization between related components. Communication between EF Connector, client applications and Cisco Finesse carry timestamps. If the system dates and time are not synchronized the system can produce unpredictable results. Therefore, please make every effort to adhere to the following time synchronization guidelines:

EF Connector, client applications and Cisco Finesse should have their Time Zone and time configured properly according to the geographic region and synchronized. To configure the time zone, please see the instructions from the hardware or software manufacturer of NTP server. Client applications and EF Connector should be synchronized to the second. This synchronization should be maintained continuously and validated on a regular basis. For security reasons, Network Time Protocol (NTP) V 4.1+ is recommended.
