What needs to be changed if we change hostname in linux
Dear all,
I have a question and will appreciate for appropriate answer(s).
My machine name was lxcms120.cern.ch and Oracle 10g DB was running fine on it (listener, DB, Enterprise Manager). It is not a production system rather a test system.
Now, i changed its name to docms11.cern.ch
I change hostname in listener.ora & tnsnames.ora and listener started successfully.
I started db from sqlplus and it started without any complaints.
Now, when i tried to start Enterprise Manager (emctl start dbconsole), it didn't and return this error.
OC4J Configuration issue. /localscratch/orahome/oracle/product/10.2.0/db_1/oc4j/j2ee/OC4J_DBConsole_docms11.cern.ch_oralxcms120 not found.
Now, i know that when the machine name was initially lxcms120, it was /localscratch/orahome/oracle/product/10.2.0/db_1/oc4j/j2ee/OC4J_DBConsole_lxcms120.cern.ch_oralxcms120
and if i go to that directory, i could see OC4J_DBConsole_lxcms120.cern.ch_oralxcms120 but of course there is no OC4J_DBConsole_docms11.cern.ch_oralxcms120
My dbname instance is oralxcms120 and has nothing to do with hostname.
So, what is the solution to the problem. Moreover, are there any steps to do while changing hostname of the oracle database like in my case which i can follow to make all required changes.
Best regards,
Anjum
