s-Server Requirements

Previous pageReturn to chapter overviewNext page

SQLstream s-Server installation requirements are as follows:




Must run 2.6.x or later kernel.

Versions known to work include Red Hat Enterprise Linux version 5 or later, Fedora Core 10 or later, Ubuntu 8.04 or later, Mandriva 2006 or later, CentOS 5 or later.

32-bit version works on all supported platforms.

64-bit version tested on Ubuntu, CentOS, and RHEL.


For s-Server, we recommend running an 2GHz Intel Core2 Duo or equivalent.

A server class processor such as an Intel Xeon is preferred. While a single core is sufficient, 2+ cores are ideal. Since SQLstream s-Server includes a multithreaded scheduler, multiple cores can improve data processing performance.

Larger caches, faster CPUs, and faster memory interconnect all improve data processing performance.

Disk space

Installed software requires 1GB. Log files, repository, and so on require an additional 1 GB.

The amount actually used will depend on how you configure logging, how many objects you create, and so on.

2GB is probably a safe minimum for an initial install.

See SQLstream s-Server Installation Directories for more information on installation directories.


Requirements for :

32-bit system

64-bit system







Production with more streams or longer data windows



Memory requirements will be application dependent: more streams or streams that hold longer data windows will require more RAM.


The server must have Java JDK 1.8 installed, not just a JRE. The environment variable JAVA_HOME must point to the location of the Java installation.

The installer will check for an appropriate version. If it does not find an appropriate version, it will try to use the native package installer (apt-get on Debian/Ubuntu and yum on Redhat/CentOS) to download and install OpenJDK 8.

Browser (for WebAgent)

In order to run the \read \write or \sqlstream apis for WebAgent, you need to be running one of the following browsers: Microsoft Internet Explorer 11 (or later), Google Chrome 31 (or later), Mozilla Firefox 17 (or later), or Apple Safari 7 (or later).
