Application Core Files

KPS — Thu, 04 Jun 2009 01:35:38 GMT

We are in the midst of troubleshooting an Application running on our BL860 HP-UX Integrity system running OS 11.23.

Application processes are aborting and writing core files for us to send to the App Vendor for evaluation, but they are being overwritten each time this happens. Is there something on the OS that we can do to prevent this from happening or is this something that the Application Vendor should be addressing in their code?

Thanks for any suggestions and/or knoweldge folks could provide on this!

On 11.31 there is coreadm(1m) so you can create unique core files. For 11.23, you might be able to use adb to turn this on. Check the "Debugging core files using HP WDB" manual:

>is this something that the Application Vendor should be addressing in their code?

Other than not aborting, the vendor can't do much except move them aside on a restart.
But typically, unless your vendor wants all of them, you probably don't need all of them.

After a little more investigation from the Apps side, it looks like this issue is being brought on because of the way this Application does it's current working directory deciphering.

Thanks for your info, but we're throwing this back at the Application Vendor to resolve.

Using tusc would enable you to figure out what the application is checking/doing with the CWD.
