"dbcache flush <databasename>"

Sometimes a database cannot be deleted while it is opened in the Domino database cache. An admin can issue a ""dbcache flush" for this case, but this clears the cache completely.

The enhancement would be an option to remove only specific databases from cache.

This would also enhance the on-line maintenance capabilities, where we also recommend to flush this cache before dbmt runs.

    The "drop dbnames.nsf" does not work for most cases. But maybe I do wrong.

    Clustered mail-db, on one server

    1 - mark replica as "out of service"

    2 - drop user

    3 - drop database

    Database cannot be deleted and is still cached (dbcache show)

    Thanks Daniel, indeed I was not aware about the drop command.

    you can use drop db.nsf

    this is what also DBMT does if a database is in use. You even see the command on the console when DBMT runs.

    On C-API I am using NSFDelete first and if that isn't successful I am taking the database offline.  This helps in most cases to delete the database.


    But if the database is in use by a user/server a "drop" and also taking the database off-line will not always work.


    You should try the "drop db.nsf"

    Daniel Nashed: You don't need to remove it from dbcache to do a copy-style compact.

    You need to close the database itself. This can be done via "drop db.nsf"
    The drop works for users and also for databases and is used by DBMT to get a database compacted.

    You can see the commands invoked on the console when DBMT detects that the DB is in use :-)

    There is a difference between open databases and databases in dbcache.

    Try the following to see the details:

    a.) dbcache show

    b.) show dbs

    And than try dbcache flush and drop db.nsf..

    Does this help? Do you still think we need dbcache flush work on single databases?
