censhare server, database and tools requirements

Hardware and software requirements for censhare Server, the database and censhare tools for censhare 2020.x versions.

What's new?

CentOS will reach its end of life on June 30, 2024. Alma Linux 9 is a new officially recommended OS for the censhare Server. Please upgrade accordingly.

There are two possible migration paths:

Recommended: Back up your existing VM, get a new one with Alma Linux 9, and set up your system based on the backup;
Upgrade your VM from CentOS to Alma Linux directly, following those instructions from the third-party provider. Pay attention to the fact that you will need to upgrade to Alma Linux 8 first; there is no straightforward way to upgrade from CentOS 7 to Alma Linux 9.

Installation by censhare

censhare offers an installation service for censhare Server. If you plan to prepare a host and let censhare install the system software, ensure that the following requirements are fulfilled:

Proper IP setup
Proper DNS setup
SSH or VNC/RDP access
Working package management system
NTP setup

Hardware recommendations

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 and a CPU speed of 3GHz or faster. Java G1 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 fewer 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.

Virtualization

censhare with all components supports Solaris Zones and VMWare ESX version 5.1 or higher.

Java Development Kit (JDK)

The censhare Server requires Java Development Kit to be installed on the host. We recommend OpenJDK version 11, except for Oracle Solaris (x86 64-bit), which does not officially support OpenJDK. On this OS, Oracle JDK 11 or other supported JDK 11 are recommended. Older Java versions are not supported.
