system requirements 2021_SysAdmin

Supported operating systems, databases, browsers and their compatibility with censhare version 2021. Read this information carefully before installing or updating censhare. If you have any doubts about the compatibility of your environment, please contact our Service desk.

censhare Server

Operating system

Database

Java development kit (JDK)

The censhare Server runs on Java and requires the Java development kit (JDK).

Hardware hints

To achieve a good performance, there are three decisive factors:

• High memory bandwidth

• CPU performance

• Fast disk drives (SSD) for the embedded database (CDB)

We recommend current processor architectures with high memory bandwidth (e.g. Intel Ivy Bridge / Haswell) and a CPU speed of 3GHz or faster. Java parallel GC (garbage collection) is a good choice for fast GCs. For more information about garbage collection see this Wikipedia article.

Calculate a minimum of 8 CPU threads for censhare. Large installations require more threads. Small installations can be run with less threads. The installation details must be calculated in the project planning phase. We recommend to calculate more CPU threads than actually necessary for additional services like a local ServiceClient or Web Client. As guiding values, calculate a minimum of 8 GB RAM and 4 core (threads) CPU for a small demo or test system.

We recommend that files for the embedded database (CDB) are located on a separate mount point.

Note on virtualization: censhare with all components supports Solaris Zones and VMWare ESX version 5.1 or higher.

Cloud services

The complete censhare platform or individual components can be installed on cloud computing platforms.

censhare Admin Client

The censhare Admin Client is required to set up, configure and monitor your system. In the censhare Admin Client, you configure Master data, Services, Modules, and Servers.

Java development kit (JDK)

Hardware hints

As a guideline for your hardware, calculate 1 CPU thread and 1 GB RAM for each instance.

censhare Render Client

The censhare Render Client is an optional component and only required for external image rendering with Adobe InDesign. For more information, see the specifications for Adobe InDesign Server.

Operating system

Operating system	Support	Versions
Windows Server		2012 2016
macOS Server		10.13 High Sierra 10.14 Mojave 10.15 Catalina (1)
		11.x Big Sur (2)

Java development kit (JDK)

Hardware hints

As a guideline for your hardware, calculate 1 CPU thread and 1 GB RAM for each instance.

censhare Client (aka Java Client)

The censhare Client is installed on the computer of the censhare user and connects to the censhare Server and database. The censhare Client can be installed with or without a virtual file system (VFS).

Operating system

Operating system	Support	Versions
Windows		8 10 (1)
macOS		10.13 High Sierra (2) 10.14 Mojave (2) 10.15 Catalina (2,3)
		11.x Big Sur (4)

Java Development Kit (JDK)

The censhare Client runs on Java. As of Java version 11, there is no longer a separate Java Runtime Environment (JRE). The Java Development Kit (JDK) is included in the censhare Client bundle.

censhare Web

censhare Web is the web interface for the censhare platform. Users access censhare Web in their web browser. If not otherwise stated, the latest version of a browser is supported. The version in brackets refers to the browser version the censhare platform was tested with.

Performance of the censhare platform with censhare Web

The performance that users experience with censhare Web depends on the network bandwidth. Therefore, performance can vary depending on whether users are working in an internal or public network. As a rule of thumb, our web application works well with a network bandwidth of 1 MB/s upstream, 100 KB/s downstream and <50 ms latency or better.

If users upload and download large files to and from censhare Web (high-resolution images, videos, 3D models, etc.), upload and download times can be significantly longer. This is due to bandwidth limitations and not caused by performance issues of the censhare Server.

You can test the client/server communication and server performance in the developer mode of censhare Web.

The file upload in censhare Web can be configured to make it robust when working with low bandwidth or network quality. 

censhare Online Channel

The censhare Online Channel is a publishing portal for editorial content, documents or media assets. It can be setup independently from the censhare Server and is not bound to a censhare Server version. For more information, see censhare Installation of the Online Channel.

Prepare your host for installation

If you plan to prepare a host and let censhare install the system software on it, make sure that the following requirements are fulfilled:

• Proper IP setup

• Proper DNS setup

• SSH or VNC/RDP access

• Working package management system

• NTP setup
