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• The Troubleshooting Guide contains outdated instructions for configuring the session timeout value on JBoss and determining the port on which JBoss is running.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.

• When using Weblogic as the application server and running real-time or batch scores with IBM SPSS Modeler streams in Deployment Manager Portal, the score execution may sometimes fail due the module pasw.scoring not loading successfully. The error message begins with "@CFMessages@Error: cannot load Module pasw.scoring." To successfully load the pasw.scoring module, you must manually update the java library path as follows:
  
  1. Go to the <$Weblogic_Domain>/bin directory, where <$Weblogic_Domain> is the directory of the Weblogic base domain.
  2. Find the file setCDSEnv.cmd (Windows) or setCDSEnv.sh (Linux or Unix). Open it and find the variable "PATH."
  3. Update the order of precedence to ensure the path related to Modeler will be loaded before SmartScore. For example, update the order of precedence as follows.
  
  set PATH=%CDS_HOME%\components\modeler\ext\bin\spss.TMWBServer\bin;%CDS_HOME%\components\modeler\bin;%DOMAIN_HOME%\smartscore\bin;%CDS_HOME%\components\reporting-engines\vis\bin;%DOMAIN_HOME%\csp\bin;%DOMAIN_HOME%\psapi\bin;%DOMAIN_HOME%\ea\bin;;%PATH%
  
  4. Save the file.
  5. Restart the Collaboration and Deployment Service Server.
• 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. This is a WebSphere Liberty issue, which failed to load the resource adapter on the AIX platform. IBM will consider upgrading the Liberty version in a future release of IBM SPSS Collaboration and Deployment Services. As a temporary work around, you may need to manually set the java library path to point to the SmartScore shared library used for the IBM SPSS Collaboration and Deployment Services Server. Contact IBM technical support for details.
• 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.
