What are the core.<nnnnn> files?

[Jerry Tilsley]

All,

I was noticing today that my HIC directory was overly large compared to what I was used to.  Upon investigating I found that i had some core. files in the exec directory that were quite large and appear to be old.  What are these files and can they be deleted?

Thanks,

Jerry

Jerry,

I find these whenever certain engine issue arise causing a core dump to be produced. What you are seeing are those core dumps I believe.

Most of the time they are not needed unless the issue that caused them to be taken has not been resolved. Then I suppose they would be helpful in further debugging and  support might want them. I have never needed to use them.

If they are old I think you can safely remove them.

It might be useful to have a task which periodically looks for files with that name structure and presents the findings so you are aware of them realtively soon and thus determine what to do with them.

Thanks Jim!

I figured they were core dumpes but wanted to be sure.  I don’t have a lot of them, but in one site that handles movements of reports and such I have a couple that are large.  I’ll keep the latest one and kill the rest.

I appreciate the help!

Jim I checked and see within our daily clean_dirs.ksh script it gets rid of any files named core as follows:

find $HCIROOT -name core -exec rm {} ; 2>/dev/null
