Chapter 1. Requirements

Hardware

Qizx is designed for running on any standard computer supporting a Java™ Runtime Environment.

The memory size required is widely dependent on applications:

  • It is quite possible to perform queries even on large databases with the default memory size (64 Mb).

  • Performing large transactions (tens of thousands of documents and collections or more) or handling very large documents can require more memory.

    It is in general reasonable to allow for 128 Mb or more. In the case of a server supporting many concurrent queries, it can be worth specifying a large memory size (e.g 512 Mb or more) to benefit from large caches (Qizx adapts the size of caches to the available memory).

Java Virtual Machine (JVM)

Starting from version 4.2, Qizx requires a JVM version 1.6 or more.

Operating System

Qizx is supported on the following OS:

  • Microsoft Windows XP, Vista and Seven.

  • Linux 2.6+.

  • Mac OS X 10.5+.

  • In general, any OS derived from Unix, where a Sun™ Hotspot JVM version 1.5 is supported, should be able to run Qizx. However no support can be provided for these platforms.

Additional libraries

No additional library is required.

The distribution includes the following utility jars:

  • resolver.jar, the XML entity resolver for XML parsing.

  • jhall.jar, the Java Help engine for Qizx Studio.
