Spatial and Routing Module

This section lists known issues for the Spatial Module, which includes routing.

JDK: Spectrum no longer installs with a JDK because Oracle does not freely distribute Java. The Spectrum installer prompts for the JVM location on the server machine so you must download and install either Azul or Oracle JVM before installing Spectrum. For a list of supported JDK, refer to the Spectrum Technology Platform Installation Guide for Windows or Linux.

Azul JDK on Linux: Users with Azul JDK on Linux require Lucida fonts for Spatial map rendering. Past releases installed this font with the Java Development Kit, which is no longer included with Spectrum. To obtain this font family, download and install the Zulu Commercial Compatibility Kit (ZCCK). Download and install instructions can be found at https://www.azul.com/products/zulu-and-zulu-enterprise/cck-downloads.

Single Sign-On: When Single Sign-On is configured for Spectrum, accessing JavaScript demo pages takes you through a sign-on flow to Active Directory Federation Services (ADFS), which prompts for a second log in. Logging in again gives access to samples.

Spatial data queries: Lowering the Remote Component Pool Size requires restarting the Spectrum server. Lowering the Remote Component Pool Size in Management Console (under Resources, Spatial) and running the workflow without restarting the server leads to an IOException error. 

Setting security: New installations do not include security permissions in Management Console on the Spatial component (to let users who are not administrators change the spatial pool size, for example). This is a known issue for this release.

MISQL and Oracle 11g: Oracle 11g reports an invalid identifier error on a Spatial column with a lowercase table alias name when used in a MISQL search. To work around this, use an uppercase table alias in a MISQL search with Oracle 11g.
