Evergreen System Requirements

$Id: f218702f3cc0e408a22cc863ab2c96155f1d9083 $

Evergreen runs smoothly on most modern computers with a good internet connection. To ensure your system is ready for migration here are a few tips and minimum requirements.

Internet Connectivity

The Evergreen staff client requires persistent connectivity to the Evergreen servers to function. Most internet traffic uses moments of brief connectivity rather than a persistent connection so it is not unusual when experiencing connectivity issues to notice it in the Evergreen staff client first.

Evergreen will work down to a 3Mbps connection, but the performance will get progressively worse the lower the connection speed gets. While Evergreen will be functionally usable at 3Mbps it may of limited use at lower speeds.

Table 55.1. Recommended Internet Connection Speeds

Category Downstream Upstream Latency (to Sitka)
Bare Minimum To Function 3Mbps 786Kbps less than 200ms
Adequate 6Mbps 1Mbps less than 125ms
Ideal 12Mbps 2Mbpbs less than 75ms

Note

Mbps stands for megabit per second and can also be represented as Mbits.

Kbps stands for kilobit per second and can also be represented as Kbits.

ms stands for milliseconds.

Most of the bandwidth usage in a library is not from Evergreen, but from other usage of the Internet by both staff and patrons. When staff workstations share an ISP connection with public workstations libraries ideally should have at least 1.5-2x more down/upstream capacity than what is recommended in the table above.

Staff Terminals

Staff terminals connect to the central database using the Evergreen staff client, available for download from https://bc.libraries.coop/support/staff-client-executables/ . The Evergreen staff client must be installed on each staff workstation and requires at minimum:

  • Windows 10, 8, 7, or Vista operating system. Win 10 users may need to manage Win 10 privacy settings based on best practice in Windows community or on advice of your IT department or vendor.

  • Mac OS X operating system.

  • Linux operating system.

  • a reliable high speed internet connection

  • 512Mb of RAM

OPAC Terminals

There is no stand-alone OPAC client for Evergreen. Patrons search the catalogue using a web browser. Each OPAC terminal will require at minimum:

  • a reliable high speed internet connection

  • a web browser (e.g. Firefox, Chrome or Internet Explorer)

Note

The OPAC will not work in Internet Explorer on computers running Windows XP. Co-op Support recommends you update your operating system or use Firefox or Chrome.

To limit your OPAC terminals to catalogue searches local configuration will be required. Please see Chapter 54, Managing Internet OPAC Stations for more information.

Barcode Scanners

Evergreen will work with virtually any barcode scanner – if it worked with your legacy system it should work on Evergreen.

Printers

Evergreen can use most desktop printers configured for your terminal to print receipts, check-out slips, holds lists, etc. The exception is spine label printing, which requires roll printers. Evergreen currently formats spine labels for output to a label roll printer. If you do not have a roll printer manual formatting may be required.

Note

Evergreen might not print correctly to receipt printers using the Windows XP Generic/Text Only printer driver. Please use a printer-specific driver instead.
