Solution for failure to start the console after Oracle modifies the machine name

After we installed Oracle10g on the machine, we found that it was still the default machine name. It was too long to remember and changed to a simple one.

Restart the system, start the console, and prompt the Agent process exited abnormally during initializat.

After searching online, the following solutions are available:

The oracledbconsoleorcl service cannot be started: Agent process exited abnormally during initialization.

The oracledbconsoleorcl service cannot be started. In the event viewer, the Agent process exited abnormally during initialization. Record is displayed. I know it is because I changed the machine name. Google solved this problem and found many people are asking, it seems that everyone often changes the machine name.

 

I found that the Oracle em generated a directory using my original machine name, which contains the relevant configuration file and is changed immediately. Start the service, OK.

D: \ oracle \ product \ 10.1.0 \ db_1 \ Solaris \ J2EE \ oc4j_dbconsole _ (computer name + Domain Name) _ orcl \ config

The machine name to be modified is shown in red.

If you have changed the computer name or added a domain name, and Oracle em cannot be started properly, you need to update the red part to your new computer name + domain name.

Then restart the Oracle service em to start properly.

After the test, the Oracle SID variable is not set.

Run: Set oracle_sid = orcl

Then execute
