Hi All, Quick question which may show just how little I still know about virtuoso; the procedures I've exposed are all via SOAP (even though I can call via REST, the responses are still SOAP encoded) Is there any way to specify that responses from a particular web service end point are encoded in

Hi Sebastian, If you shutdown Virtuoso gracefully it should automatically run a checkpoint to commit all pending transactions (or you can run one manually at anytime with the "checkpoint" command) with the log file being zero bytes in size and thus nothing has to be replayed on startup. Are you

Is there any way I can speed up the start of Virtuoso? Maybe by issuing some command before shutdown which already plays back all the transactions in the log file? Cheers, Sebastian
