FileCache error on a Blueworx Voice Response VoiceXML 2.0 system with multiple application Nodes

When running a Blueworx Voice Response VoiceXML 2.0 system configured with multiple application nodes, a FileCache failure can occur with one of the following descriptions:

• 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.

Use a separate FileCache directory for each application node, by configuring the system as follows:

1. Stop the VRBE environment by running'dtjstop followed by dtjshost -exit.
2. Edit the VRBE configuration file /var/dirTalk/DTBE/native/aix/default.cff. In each of the application node configuration sections, add (or modify) the JavaCommand entry so that it includes the following parameter:

   -Dwvr.vxml2.cachedir=/var/dirTalk/DTBE/native/aix/VXML2Cache/<cachename>

   where <cachename> is a unique name for each application node. (You could use the application node name.)
3. Save the changes and then import the new configuration using the dtjconf command.
4. Restart the VRBE environment by running dtjshost followed by dtjstart.
