Hello,

I changed the listener content as you said. But still having the problem...


# LISTENER.ORA Network Configuration File: D:\oracle\ora92\network\admin\listener.ora
# Generated by Oracle configuration tools.

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
(ADDRESS = (PROTOCOL = TCP)(HOST = VALUED-CB7D4C82)(PORT = 1521))
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\ora92)
(PROGRAM = extproc)
)
)


Here is the error message after changed the listener.ora as above.
