Return to chapter overview

SQLstream s-Studio and s-Server requirements (hardware and software components) are as follows:


Specifics (size, version)


1GB of RAM plus 100MB of hard disk space, plus some additional space for the s-Studio log file. The size of this file is can be adjusted by the user or admin.

A Sun Java runtime environment (JRE) of either Java 6 or Java 7 available at both install time and run time; and

A network connection to the SQLstream s-Server.


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 5, and RHEL 5.x.


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 a Sun Java JDK installed before installing SQLstream, not just a JRE.

JDK versions 1.6 and1.7 are supported.

The installer itself requires Java, and will check for an appropriate version.

(To download the latest JDK, see Downloading the Java SDK.)
