Moving/compressing *.trc files.

Hello all,

Is it safe to move/compress (gzip) *.trc files from oracle [b|u]dump
directories while database instance is up?

I'm getting some of these files growing much more than expected (due
to a known bug...) and would like to know if i can safely move them
automatically to another directory using an script or similar.

Thanks in advance.

Regards.
