Thread Silly question about Database Server

New to the database server, so bear with me...

How does one empty table, alter table, etc. from DBSys, ie functions
required Exclusive access ?

I have DBsys open, the DBSrvr shows only one connection so I know there are
no other connections,
I'm getting access denied when I try to empty table, or any other function
requiring Exclusive access.

What have I missed ?

Thanks

As long as you're the only connection to the table it should just work -
is OK here. i can empty or alter a CS table just fine.

Make sure you don't have any tables or queries open in the DBSYS when
you do empty/alter - dbsys maintains a single connection to DBSRVR but
you can still have multiple query/table windows active in dbsys.

Same applies to make any non-CS (meaning direct file system) connections
to table.

Yes, you are correct, it *should* work.  But I can consistently get access
denied when the DBServer shows only 1 connected session
which is DBSys.  There are no other processes running that use dbisam, just
the IDE and there are no active sessions within the
Datamodule

I'm not saying it should but that it works for me OK - dbisam 4.35b2.

Just to simplify the issue:
- close IDE to eliminate it completely
- run dbsys and make sure there is only 1 query window open in dbsys
(since all the dbsys windows share the single session)

Are you still getting the error ?

Do you have anti-virus running - any chance its locking the tables?

you could use somethign like Sysinternals Process Monitor
(http://technet.microsoft.com/en-us/sysinternals/bb896645) to all file
access attempts against the table(s) in question just to confirm only
dbsrvr is accessing the tables.

Hi John,

Another suggestion that I'll throw forward is:

1) Close all users out of the application.

2) Stop the DBSRVR service/application.

3) delete any .lck files in the database location. (These may be hidden,
so you may need to do something to deal with these first).

I normally use the command prompt and execute the following in the
database location

attrib *.lck -r -a -s -h
del *.lck /s

4) Just for good measure, reset the permissions on the directory, and
set to apply to all subfolders and files.

5) Restart, and see how you go.

Cheers

Adam.
