Database lock acquisition failure and hsqldb

Question

I was trying to connect to a hsql db. I created one by running from C:\\myhsql:

java -cp .;C:\\hsql\\lib\\hsqldb.jar org.hsqldb.Server -database.0 file:db\\m         


        

Answer 1

I face this error because I wanted to view a currently opened database in another client like IntelliJ database while the server is using the same db

so to make hsql db able to be connected to multiple clients, use

hsqldb.lock_file=false

so the connection url will be like

jdbc:hsqldb:file:./db/myDbInFile;hsqldb.lock_file=false
