    Hi All,

    I have restored a database(nebula) in another test machine (sylvester), i did shutdown the aready running instance and have added the TNS_ADMIN=/u2/backup export TNS_ADMIN in .profile of my test machine for listener location. After successfully restored the nebula database, when i checked the instance name it was showing SYL02 i.e for SYLVESTER and when i shutdown this instance and start my actual database the Listener was giving the following errors :

    When i remark the TNS_ADMIN=/u2/backup and start the listener, it started and working.
    Please suggest what should i change in the listener.ora and which listener.ora i should change..?? Also what should i do to run multiple instance simulataneously.

    Your help will really be appreciated.

    Sami

    when you don not specify the TNS_ADMIN variable, the listener
    will be searching in $ORACLE_HOME/network/admin if he finds
    a listener.ora file.

    I think that the listener.ora file from $ORACLE_HOME/network/admin
    has no reference to tweety.... , so it starts.

    if you start without the TNS_ADMIN set, and you do lsnrctl status,
    do you also see the TCP protocol activated ?

    Mainly, i think there's a problem with your /u2/backup/listener.ora file.

    Can you do a ping tweety.linmor.com ??

    Post your listener.ora / sqlnet.ora from /u2/backup

    Hope this helps,
    Regards

    Gert
