Additional requirements

From version 7.1.0, the Java DataSource API uses the Caplin Nanotime to support nanosecond timestamping.

By default, the Caplin Nanotime native library is extracted to, and loaded from, the /tmp directory. If the /tmp filesystem has been mounted with the noexec flag, then Java cannot load the Caplin Nanotime library.

To resolve this, set the application’s java.io.tmpdir Java system property to a directory to which the application user has write and execute permissions. The java command that launches the application is in the application’s DataSource/bin/start-jar.sh script:

Example: specifying the Java temporary directory
java -Djava.io.tmpdir=/home/caplin/tmp existing_arguments
