I routinely refresh my DEV instance with a backup of my PROD instance. After I test recovering PROD on the dev machine I create a new control file and rename the instance to DEV with the following: CREATE CONTROLFILE SET DATABASE "DEV" RESETLOGS ARCHIVELOG Now for the strange part. In DEV there is NOT a dblink for PROD but the query select * from APP_TABLE@PROD ; returns rows. I would expect a ORA-02019 error. The returned rows are actually coming from the DEV instance and not PROD. This isn't the end of the world for me by no means. The instance will be refreshed over the weekend and I told the programmers there isn't a dblink to PROD and to not try. I just thought this was a strange behavior and was wondering if anyone else had come across it. 8.1.7.3 Thanks - Mike --------------------------------- Do you Yahoo!? Yahoo!
