WebLogic a solution to the problem!

When using WebLogic to do Web server, the server is Linux, there is a service automatically stopped, and then restarted on how also can not start, anxious to die. Always quote the following error,
The WebLogic server did not start up properly
Exception raised:
Weblogic.server.serviceFailureException:could not get exclusive access to embedded LDAP data files due to existing server
At Weblogic.ldap.EmeddedLDAP.reExclusiveAccess (embeddedldap.java:899)

Later used a most worry method, is to/user_projects/domains/mydomain/myserver/the LDAP directory under the name, or delete, the problem is solved. But it's not yet known what caused the mistake.
