This issue that i had done it by changing OS ,then everything is ok. I used win2003 server to install Weblogic domain fro odi11g ,Now i had to change to install it by xp os.Now i can exercise on xp platform to using odi11g.
i managed to solve the problem. what i did was the following:
1. go to your middleware home directory and acces the user_projects subdirectory
2. go to applications/your_domain and delete the folder em if this one exists
3. go back to user_projects and enter domains/your_domain/sysman4. from here delete the folders state and mds
4. start the config.sh script and extend your domain only for the EM.
5. instalation should complete!
6. extend your domain with other features with previously also needed EM.
