FILEWATCHER CHANGE EVERY 10 SECONDS PASSWORDThere was an exploit back in 11gR2, which meant that it was possible to discover the password of the OS user used in a credential. The easiest way to achieve this is simply to create a credential for the oracle OS user. load data) then the OS user that started Oracle (usually oralce) will also need to read these files. If we’re going to do anything with the files (e.g. We’re going to need access to an OS account that can read the files as they come in. If we check again we should see that the FILE_WATCHER_SCHEDULE now reflects the new repeat_interval : …where pdb1 is the name of your container database. To achieve this, I need to connect as SYSDBA and run… Therefore, I’m going to set it to run every minute. Speaking of which, testing will be rather less tedious if we can make the filewatcher run more regularly. This distinction will become more relevant when we start testing. What this means is that the filewatcher will check every 10 minutes to see if any file it’s looking for has arrived since it last checked.Īctually, what it means is that the filewatcher will check to see if a file it’s looking for exists and has a timestamp later than the last time it checked. Where schedule_name = 'FILE_WATCHER_SCHEDULE' Of more immediate interest is the schedule, which will tell us how often a filewatcher will run : STORED_PROCEDURE dbms_isched.file_watch_job File Watcher program Select program_type, program_action, commentsĪnd program_name = 'FILE_WATCHER_PROGRAM' If we look at the program, we can find out more details about what Oracle runs under the covers when a file watcher is initiated : We can see that the job is associated with both a Program and a Schedule. SYS FILE_WATCHER_PROGRAM FILE_WATCHER_SCHEDULE File watcher job PROGRAM_OWNER PROGRAM_NAME SCHEDULE_NAME COMMENTS Select program_owner, program_name, schedule_name, Let’s start with the main scheduler job itself : It’s probably worth taking a whistle-stop tour through the data dictionary views that provide some detail about how Oracle’s file watcher functionality hangs together. Finding and Configuring File Watcher settings However, Express Edition is missing one of the components required for the File Watcher mechanism to work, namely the DBMS_ISCHED.FILE_WATCH_JOB procedure. I would normally run something like this on Oracle 18cXE. The examples that follow have been tested on Oracle Enterprise Edition 12cR2 ( 12.2.0.1.0) running on Oracle Linux 7.3. More specifically, don’t try this on Oracle 18c Express Edition.
