Thanks in advance.

The error means that a "plocal" database can't be opened by multiple JVM at the same time. To fix:

• check if there's no process using OrientDB (most of the times a OrientDB Server is running in the background). Just shutdown that server and retry
• if you need multiple access to the same database, don't use "plocal" directly, but rather start a server and access to the database by using "remote" protocol. In this way the server is able to share the same database with multiple clients.

Hope it helps

Answer 2

I had exactly the same issue when I upgraded Nexus from 3.7 to Nexus 3.20. The problem was that I executed the command nexus.exe / before this command nexus.exe /run. This is how I solved the issue:

• First uninstalled Nexus 3.20 and installed it again
• Executed nexus.exe /run
• Created the service nexus.exe
• Checked localhost:8081 and the Nexus interface appeared
