SDM could not start the J2EE cluster on the host Error on Deployments

Question

Hi,
We are sudenly getting this Error when trying to make a Deployment in the NWDE:
Settings

And in the sdm log file we got this kind of errors:

Any Idea what can be wrong? we have even restarted de AIX Server and starting all the services and it is still not working.
Thanx in Advanced!

Hi Gerardo,
I encountered exactly the same error, but had a different solution as I was expecting from the error-message.
In my case I was forced by the Visual Administrator to change the administration password, since the time was up on it. But as the password for the Visual Administrator is saved within the database, the password for the SDM is stored within the secure store (file-system) and changing the password just in VA will not automatically change it also in the secure store. But since both passwords for the internal usage need to be equalized, I encountered problems afterwards when trying to deploy something and I got the same error message. However the sense of restriction is meant here, the solution on it was rather simple as follows (Just note that you need to enter a dummy-password first, before setting the correct one similar to your visual administrator):
1. create a telnet session to your J2EE using a command line shell
2. enter "jump 0" to get on the correct node within your J2EE
3. enter "add user" to gain access to user-specific commands
4. enter "password <Administrator> <temporarily new password>"
5. exit
6. create another telnet session to your J2EE using a command line shell
7. after succeeded the login, you will now be forced to enter a new password - so enter "password <Administrator> <origin password of the Visual Administrator>"
8. exit
9. now start the config-tool of the engine
10. apply to the DB-default-question with "yes"
11. select the Secure Store on the left
12. select the entry "admin/password/..." that you can see it in the bottom lines.
13. click "Remove" to delete it from the list
14. set the password similar to the Visual Administrator password within the "Value" line (take care as you can not see the digits).
15. click "Add" to add it back to the list
16. click the disc symbol in the top of the UI to save the new password (if you don't get a dialog afterwards that the data has been stored, something may hasn't worked fine when removing/adding the password-entry, in this case repeat the action on it).
17. After exiting the config-tool, you need to restart the entire J2EE.
18. Your hopefully finished by success ;o))
Best regards
