I am trying to make sure I understand the way file-based cursors work: Am I right in thinking that temporary files is functionally the same as memory with respect to transactions and data security? If the system was to crash and it somehow lost or corrupted temporary files, would it be possible to restart and get those messages (those that ended up in the temporary files) back from the message store? TIA,
