FileCache failures when running VoiceXML applications

When running applications on a Blueworx Voice Response VoiceXML 2.0 system configured with multiple application nodes, a FileCache failure can occur with error messages similar to the following:

• "Cannot lock a file because of a potential deadlock condition"
• "Unable to obtain exclusive file lock"

These errors are logged in the standard log.n.log files in the /var/dirTalk/DTBE/dtj_logs directory.

As these problems only arise when multiple applications nodes are configured, the solution is to use a separate FileCache directory for each application node, by configuring the system as follows:

1. Stop the Java and VoiceXML environment by entering the commands dtjstop followed by dtjshost -exit .
2. Edit the configuration file for the Java and VoiceXML environment, /var/dirTalk/DTBE/native/aix/default.cff, so that in the configuration section for each application node, you add (or modify) the JavaCommand entry as follows:

    -Dwvr.vxml.cachedir=/var/dirTalk/DTBE/native/aix/VXML2Cache/<cachename>

   where <cachename> is a unique name for each application node (you can use the application node name itself).
3. Save the changes, then import the new configuration by entering the dtjconf command.
4. Restart the Java and VoiceXML environment by entering the commands dtjshostfollowed by dtjstart.
