    Core files are generated becaus of program errors.

    - Is this the first time that error occured?

    - Which OS are you using?

    - Which kernel patchlevel and database are you using?

    - Is the problem reproducible?

      Hi Deve

      Why not give a try utilizing an idea given in the script for deletion of core files, which we are already using in our servers, as posted in my earlier reply....and as suggested by Sukarna too.

    Hi Deve

    you can schedule a job/script in crontab which will prohibit the generation of core files of more than 50MB or 02GB size (for eg.) at OS level.

    Hi

    We can not prohibit the generation of core files of various sizes.Core files can be generated with various sizes.

    We have to schedule a job/script in crontab for deletion of core files,when core file is created
