Dear ccp4i developers,
Jumping into this issue a bit late...
I have some criticism to make here, please take them friendly, I make
them precisely because ccp4i is so useful.
I presume there are good reasons behind the new design of CCP4i and
its CCP4 DBhandler, but I think you have overlooked the fact that
multi-processor, multi-user servers are quite common nowadays. Also,
that many end-users don't know/don't need to know what a sqlite
database is and will simply let the default preferences turned on,
unaware of the consequences.
In our lab this has led to people not using the best computer they
have available, precisely by reasons similar to those raised by Jun
Dong. I know of another case where a user got its database corrupted
after getting confused because not being able to see their own
projects/directories.
I hope that in future versions of ccp4 the multi-users problem will be
tackled or, at least, the default option is the old direct-access
behaviour (if completely functional).
With best regards,
Miguel

Dear Jun Dong,
This is a problem with the new mechanism used in CCP4 to store
project and job data (the CCP4 DBhandler). The quick fix for now is
to turn it off and use the old mechanism for storing the project
data. To do this in the CCP4i interface go to "System
Administration", select "Database Configuration" and un-check the
radio button that sets the option to connect to the database server
on start up. Then have all your users restart CCP4i.
Kind regards,

Dear CCP4 developers,
I just wonder if there will be a fix for this problem. Basically
when the first user is running ccp4i on a linux server and then
when the second user tries to run ccp4i on the same linux server,
the second user will only see the fist user's Directories&ProjectDir.
