Additional requirements from Java DataSource API 7.1.0

From version 7.1.0, the Java DataSource API uses nanosecond timestamping. Java 11 provides built-in support for nanosecond timestamps; Java 8 does not. To support nanosecond timestamping on Java 8, the Java DataSource API uses a Caplin native library, Caplin Nanotime.

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
