Hi, I have a multiple instance JBoss. I face this Database lock issue. Actually i dont need any database for my 2nd instance. How do i remove it ? WARN [ServiceController] Problem starting service jboss:service=Hypersonic,database=localDB java.sql.SQLException: The database is already in use by another process: org.hsqldb.persist.NIOLockFile@114fd341[file =/....//.../data/hypersonic/localDB.lck, exists=true, locked=false, valid=false, fl =null]: java.lang.Exception: checkHeartbeat(): lock file [/u/hcdev101/apps/hca/jboss/server/logviewer/data/hypersonic/localDB.lck] is presumably locked by another process.
