I think its time to do full maintenance on the IDB (purging) then perform a writedb and a readdb....

Hello

You have reached DP 5.5 limitation for DCBF number

DCBF Size and Growth
. The maximum number of supported directories per cell is 10.

Maybe update unsupported version from 6 or 7 years ago is good idea......

Best Regards

Thank you for your reply.

you are right, we never purge the DB and we are afraid to do so at the risk of losing data.
Thank you to send us the steps to follow to minimize risk.
Thanks again

you have an IDB backup so this is fine. You need to run "omnidbutil -purge -filenames" at a quiet time but its likely to run for some time. You can stop the process with "omnidbutil -purge_stop" then start it again another time.

look at the other omnidbutil -purge options too as you can also use -dcbf for media too.

once done, perform the following.........but make sure you have enough space in a location to write the DB out...

omnidbutil -writedb -mmdb /location/mmdb -cdb /location/cdb

once complete, perform this....

omnidbutil -readdb-mmdb /location/mmdb -cdb /location/cdb

In your specific case, purging alone will not help with anything and rebuilding the IDB after purge will only reduce your fnames.dat* footprint, but you are hitting the DCBF directory limits. These have been bumped up in later versions and the entire IDB became way more scalable in 8.0+ but given you are still on 5.5, upgrading through that chasm of time and code churn isn't going to be an easy feat.

Is there any way you can get rid of some protected catalogs? That is what blows your DCBFs now. If you really have a large pool of media kept intentionally at Permanent (or otherwise very long) protections, consider reducing catalog protection for the oldest stuff somewhat - it can be reimported if need be, but it doesn't have to fill your disks in all eternity.

HTH,
Andre.
