Failure test failed: Network adapter

Hello !

I ask for help with entering Database sql 11

The following error is:

Failure test failed: Network adapter

What was done (undertaken):

Changed the name of the computer put localhost , hostname - did not help

Logged in under the login sys, system and standard password oracle, the password during the installation did not help

changed the service name to orcl - did not help.

I watched the listener.ora file

changed host to localhost and hostname

Removed hostname - did not help.

 # copyright (c) 1997 by the Oracle Corporation # # NAME # listener.ora # FUNCTION # Network Listener startup parameter file example # NOTES # This file contains all the parameters for listener.ora, # and could be used to configure the listener by uncommenting # and changing values. Multiple listeners can be configured # in one listener.ora, so listener.ora parameters take the form # of SID_LIST_<lsnr>, where <lsnr> is the name of the listener # this parameter refers to. All parameters and values are # case-insensitive. # <lsnr> # This parameter specifies both the name of the listener, and # it listening address(es). Other parameters for this listener # us this name in place of <lsnr>. When not specified, # the name for <lsnr> defaults to "LISTENER", with the default # address value as shown below. # # LISTENER = # (ADDRESS_LIST= # (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521)) # (ADDRESS=(PROTOCOL=ipc)(KEY=PNPKEY))) # SID_LIST_<lsnr> # List of services the listener knows about and can connect # clients to.

The password must be set before running the next # command. # LSNRCTL> save_config # Will save the changed password to listener.ora.
