Hi,
I had a w2k crash which needed a partial re-install. I have also re-installed Oracle 9 & Oracle DS. This is on a local desktop machine. Towards the very end of the install there was a glitch (possibly because I didn't know how to answer some net setup questions ?). Now when I try and startup my old db I get

ORA-12541: TNS: no listener

I have searched on the newsgroups and tried this

c:\> lsnrctl

and then:

LSNRCTL> start
Starting tnslsnr: please wait...

What file/directory is this referring to & is that the problem or a red herring ?
Where it referrs to HOST=**.*.***.*** - that is the IP of my cable modem - why ???
Also, in the listener.ora & tnsnames.ora there are two entries that I don't understand:

# LISTENER.ORA Network Configuration File: C:\orant\network\admin\listener.ora
# Generated by Oracle configuration tools. LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = MYHOST)(PORT = 1521))

)
)
)

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = C:\orant)
(PROGRAM = extproc)

)
(SID_DESC =
(GLOBAL_DBNAME = myGlobal)
(ORACLE_HOME = C:\orant)
(SID_NAME = myGlobal)

)
)

# TNSNAMES.ORA Network Configuration File: C:\orant\network\admin\tnsnames.ora
# Generated by Oracle configuration tools. MYGLOBAL =
(DESCRIPTION =

)
)
INST1_HTTP =
(DESCRIPTION =

)
(CONNECT_DATA =

)
)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
(CONNECT_DATA =
(SID = PLSExtProc)

)
)

What are "PLSExtProc" & "INST1_HTTP" ?
Can any kind soul help a newbie out ?

thanks
