I already have Listener.ora file created with some entries...
==========================================
[oraosc:/u10/app/ORACLE/product/10.2.0.1/network/admin]cat listener.ora
# listener.ora Network Configuration File: /u10/app/ORACLE/product/10.2.0.1/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = oscora01)(PORT = 1521))
)
)
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = extproc))
)
)
)

LOGGING_LISTENER = OFF

TRACE_LEVEL_LISTENER = OFF

=====================================

i created the database using DBCA and i never made any configuration changes to net services. SO 10g is using Dynamic configuration by default..

I want to change that to Static. How do we do it ?

thanks
Ron
