    Hi,

    Sorry for this late summary. I have tried and test the solution
    successfully. Here is my primary question.

    >I need to modify the shutdown action of SunCluster for oracle adding some
    >sql lines before the "shutdown immediate" action. Please share your ideas
    >about how can it be changed.

    Thanks to Allan McAleavy for his ideas about modifying the stop method. As
    he warns, this would invalidate the support agreement with sun b/c stop
    method scripts is part of the package.
    But maybe there is a lack of flexibility in sun scripts. I did the following

    check the scripts called to stop the DataServer and find it actualy is
    /opt/SUNWscor/oracle_server/bin/oracle_server_stop

    in this script you can find the line
    su $ORACLE_OWNER -c "$SERVER_MANAGE shutdown immediate" >> $DBUG_FILE

    $SERVER_MANAGE is defined some lines earlier as
    /opt/SUNWscor/oracle_server/bin/oracle_server_manage

    which was the script I finaly modified. In that script in the shutdown
    stanza you can find some line like:
    srvmgrl <<
    connect internal
    $@

    And I inserted my additional sql statemente (basically dumps to disk before
    stopping) befor the line "$@" which stands for the external argument
    (shutdown immediate).

    The sql statements must finish with a ;

    For debugging look at the $DEBUG_FILE

    -------------------------------

    Another solution suggested by Mazhar Khan is to use "start before" and "stop
    before" methods, but I didnot managed to find them so I think that methods
    should be defined some where in the RTR file for the resource type. Although
    that whould be a more elegant solution is also more complex.

    Thanks to both of them for sharing their ideas.

    Cirus.
