Hello everyone
 
I have an error "[db:lock] Database 'db' cannot be updated, it is opened by another process".
While client's "reading" query from 'db' in progress, I query "db:alter('newdb','db')" for the same database.
How can I wait for ending client's query and then "db:alter('newdb','db')"?
 
Thanks for your help!
