Problem Description: Server not coming up after restart. (You will find error in log like: “Could not acquire lock on ldap … already in use …”)
Possible causes: Server did not shutdown properly though in console you will see the status as SHUTDOWN / UNKNOWN
Solution:
- Logon to UNIX box.
- Switch user to the user owning the domain
- Run “/usr/ucb/ps –auxww | grep java” and see if the process is running.
- Use “netstat –an | grep <port number>” to see whether any process is listening on the port.
- If you find the process, kill it using “kill -9 <PID>”
- Start the server instance.
Problem Description: Server not coming up during admin password change (You will find errors saying “boot identity is not valid …” and “Authentication denied”)
Solution:
If weblogic version is 8.1
- After doing regular tasks for password change (upto shutdown). After changing the password and shutdown,
- Logon to UNIX box
- Go to DOMAIN_HOME
- For each managed server there will be a folder naming <managed server’s name>
- Rename the folders with <existing name>.<current date> (remember to rename not copy)
- Now start the managed servers. It will start and create the above folders again.
For version 9.2 and 10
-
You will find the folders at DOMAIN_HOME/servers/
-
Follow the same tasks for 8.1
-
Also remember to write the new password in DOMAIN_HOME/boot.properties and DOMAIN_HOME/servers/<Admin Server’s name>/security/boot.properties
