Updates, limitations, and known problems

Documentation updates, limitations, and known problems are documented as individual entries in an online knowledge base. As problems are discovered and resolved, IBM Software Support updates the knowledge base. By searching the knowledge base, you can find workarounds or solutions to problems.

At the time of publication, the following issues were known:

• The Troubleshooting Guide contains outdated instructions for configuring the session timeout value on JBoss and determining the port on which JBoss is running. The correct instructions are as follows:
  
  Once a user is logged in to the repository, a period of inactivity is allowed before the session is terminated and the user must reauthenticate. To increase or decrease this value:

  For JBoss EAP 6.x, see https://access.redhat.com/solutions/31400.

  For JBoss EAP 6 up to 6.3, it's not possible to set the session timeout globally because there's no global web.xml file and there's no setting in the web subsystem. The default HTTP session timeout in EAP 6 is 30 minutes and it's hard-coded at the container level.
  Starting with JBoss EAP 6.4, you can modify the default session timeout by changing the default-session-timeout attribute of the web subsystem. For example, setting it to 15 minutes as follows:

  /subsystem=web:write-attribute(name=default-session-timeout,value=15)

  results in the following XML:

  <subsystem xmlns="urn:jboss:domain:web:2.2" default-virtual-server="default-host" native="false" default-session-timeout="15">

  The JBoss application server's HTTP port is defined in the file:  \standalone\configuration\cds_server.xml

  Alternatively, from the command line, you can use the netstat command to view applications and the ports that are in use.

• Scenario files (.scn) are no longer supported. Enterprise View source nodes cannot be modified in Deployment Manager. Old scenario files can be modified in IBM SPSS Modeler client and resaved as stream files. Also, scoring configurations that used a scenario file must be deleted and recreated based on a stream file.
• Analytic Data Views do not currently support the TM1 node.
• The current IBM SPSS Collaboration and Deployment Services SmartScore Score Provider (used for processing PMML files) provides different scoring results, when compared to previous versions, for streams that contain C&RT, CHAID, and C5.0 models. The scoring discrepancies are the result of the updated scoring provider that uses the PMML confidence or probability. The PMML confidence or probability values are correct and should always be used (previous IBM SPSS Collaboration and Deployment Services version did not use the values).
• The Liberty Scoring server does not work on AIX and Power Linux.
• When you use IBM Installation Manager wizard mode, if you select IBM SPSS Collaboration and Deployment Services, IBM SPSS Collaboration and Deployment Services - Scoring Server, and one or more scoring adapters for installation, the scoring adapters will be installed to the scoring server only. To install the scoring adapters to the IBM SPSS Collaboration and Deployment Services server, you must rerun the adapter installation. Alternatively, you can use silent mode to install the scoring adapters to both servers. The resolution is documented in Technote 1654658.
• When you use the default shell to run the startserver or shutdown scripts for the remote process server, a syntax error occurs. To successfully run the scripts, use the Bash shell. The resolution is documented in Technote 1695846.
