Thanks... :confused:

Since Oracle 9i is a networking component, you need to provide the database name in the HOST STRING entry. It is nothing but the database name what you created at the time of installation. Try with this. This may solve your problem

go to cmd prompt


type

c:\set ORACLE_SID=(ur database name)

conn system/(urpassowrd)@dbname

hopefully it should work

Dear chek the tnsname.ora file it resides in your system in ora92\network\admin
If this file contains your DB name entry then check in the services that you listener is running or not check it and revert back

Check addresses used for proper protocol specification.
Before reporting this error, look at the error stack and check for lower level transport errors.
For further details, turn on tracing and reexecute the operation.
Turn off tracing when the operation is complete.

What tool are you using ? SQL*Plus or something else ?
