I have scheduled a job to run a batch file which exports a schema , every day in 3 P.M. ,
1. What is your question or issue?
2. What does you question or issue have to do with Sql Developer?
Unless this is a Sql Developer question please mark it ANSWERED and repost it in the General DB forum
When you repost provide the code you used to create the job. And because your start_date uses an unusual format also post the NLS settings you are using.
If the job hasn't run at all it could be that the start_date you provided is either in the past or far into the future.
As others mentioned, mark this question "as assumed answered"
