Anyone seen this: DbccFilesCompact?

  • I took too long writing this the first time and all my work got tossed out when I hit "post new topic".

    So, I'll keep it short:

    Job running too long, SQL agent ran a process called "DbccFilesCompact" that was taking lots of CPUs. Is this related to DBCC SHRINKFILE?

    The DB still seems to have space to grow. Would it run shrinkfile on itself if some space limit were reached?

    Thanks!

  • I think so..

    If the AUTO SHRINK database option is enabled, it will shrink automatically based on the free space other wise not...

  • Hmm, Auto Shrink is off.

  • I see the same thing when i run dbcc shrink file in 08.

  • Just to be clear, you should not be regularly running shrinks. This is for emergencies only. Keep free space in your files to handle normal operations.

  • I only use it on our support environments after my nightly restores.
