Re: [basex-talk] db:copy

[Ветошкин Владимир]

Hi,

 

I have upgraded java version to 21. The problem is gone.

Thank you.

Yes,

Are they use different methods to copy databases? Or that jdk bug only?

 

It’s exactly the same; when db:copy is called, the function isn’t aware of whether it has been called by a server or standalone/client instance.

 

Are you sure that both the server and the standalone version of BaseX use the same JRE? You can e.g. check this with the following query:

 

for $p in proc:property-names()[starts-with(., 'java.vm.')]

return $p || ': ' || proc:property($p)

Hi, this definitely looks like a bug in the JDK context. What happens if you upgrade your JDK to a newer version?

Best, Christian

Hi everyone.

 

Since I have changed jdk version to 12 (azul) - I get error, when I copy database (db:copy).

It's only in basexserver. When I run basex - everything is ok.

 

Error:
