Hi,

Yes, it's opened by client's query first. While that query is in progress, I query "db:alter" for the same database. How can I query "db:alter" after first query ends?

Thank you

Hi, It seems that might be your DB is opened or your DB has Benn crashed

Thanks

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!

Hi Vladimir,

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')"?

Which client/interface did you use to send db:alter? See [1] for more information on concurrent operations on databases. Best, Christian [1] https://docs.basex.org/wiki/Startup#Concurrent_Operations
