Host string(s) on NT

How can we find out all the valid host_strings to login to SQL*plus on NT?
Tried leaving it as blank and logging in a system/manager, scott/tiger... but neither worked.
Please advise ASAP.

The easiest way is to run the Network Configuration Assistant. This will show all of the names and how they are defined.
If you don't have this installed you will need to look in the tnsnames.ora file.

I think the problem with host string.
actually when we are trying to enter into the oracle sql,it asking the username,password and host string.I mentioned the username and password in variables tab.I don't know where I have to mention the host string name.
Please any one help on this.
Thank you,
D.Nagireddy.

I would say that, since the OP has so little info, there are no policies in use. It there were then this question would never be asked the way it is being asked.
I had a client call with a letter from their insurance company; an accountant with malpractice insurance. THey asked the same question inmuch the same way. "What computer can you users access?" The question should be more like
"Do you have a policy that restricts access to computers and do you audit for compliance?"
I have had other clients whose insurance asked the question in that way. It produces a better view of what should be happening and how to show compliance.
I recommend that companies being asked these questions by their legal departments or insurance companies should contract with a god computer security consultant to assist with answering these very tricky questions. Of course if it is just you boss's
curiosity then you may need to discuss his requirements with him in more depth.
¯\_(ツ)_/¯

Host String Problem

Hi everyone, i searched the forum and found same problem with me but i did not work for me. The problem is i cannot connect my sql plus. i enter my username and password then it asks me gor host string but when i type it and enter "ok" it says "TNS Listener does not currentl know of service requested in connect descriptor. i looked at my tnsnames.ora file and is exactly like this.
# tnsnames.ora Network Configuration File: C:\oracle\product\10.2.0\db_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
CSE348 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = Canavar)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = cse348)
So what shoul i type to connect sql plus?

Given the tnsnames.ora content, the following needs to be entered for sqlplus in order to have it use that connection string in the file:
sqlplus scott/tiger@CSE348As you have not qualified the alias with a domain, it will default to "+.world+" as far as I recall. If the default domain in your local sqlnet.ora differs, than that default will be used to find alias CSE348 in the local tnanmes.ora file. So make sure that you do not mix default and explicit domain names. Rather specify a default domain in sqlnet.ora and use the same domain for defining full qualified domain name TNS aliases in tnsnames.ora.
As for the error - the Listener receives a connection request for a service called cse348 - and no such service has registered with it. You can check the known services of the listener using the "+lsnrctl services+" command on the server.
Often in this case, it is easier to request a specific database instance using its system identifier, or SID. In which case you can change your connection string for the alias to use a SID as follows:
CSE348 =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = Canavar)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SID = cse348)
)This assumes that the SID is cse348. The default SID is for example orcl. SIDs like dev and prod are also often used.

Oracle 8i Lite: logging to sql plus - uid, password, host string - whats that

If i install "Oracle 8i Lite" (just locally, not networked). There are two important things : "Navigator", and "SQL Plus". If in navigator, I create a local database called "xxx" (tables under 'system' user). Then if i need to query - i go to SQL Plus. Fine, but how do we log in - what is the "host string" ?.
The login needs, Userid, Password, Host String. In some docs, it said the userid, password for 'system' account is 'system, manager' respectively. Anyways, now the host string , i had read the 'host string' will be like "@databasename", so I think for me, it will be "@xxx"
But the way, I'm understing, i cant log, and SQL Plus says something "TNS: could not resolve service name". Maybe i have to something with that tnsnames.ora file....?
Incase, you could give ANY information, kindly inform.
Thanks

Host string usually refers to the host string that is stored in your TNSNAMES.ORA file. You can open TNSNAMES.ORA with a text editor.
If you get "TNS: could not resolve service name", it's either you have not start the database or your configuration in TNSNAMES.ORA is wrong.<HR></BLOCKQUOTE>
hi,
iam getting the same error(the TNS thing)can you be a bit more explaining regarding how to solve the problem.

Maybe you should have provided a bit of detail to "doesn't seem to work".
I hope you didn't build a whole new house just because you couldn't get the key fit the front door . . .

Password and host string

Hi,
Im trying to get the Oracle 8i for 2000 to run correctly. I did a download. Problem is getting pass the password screen. The host string is giving me trouble. What should go there? Any place where the password and host string info are stored for later retrieval?
thanks,
Cindy

If you installed the default database then you should type in system as the user and manager for the password and ORCL as the host string (these are the defaults).
The hoststring names (database aliases) would be in the tnsnames.ora file uder your Oracle_Home/network/admin directory
If you login as system or a user that has DBA privileges, you can change passwords as you see fit
syntax:
alter user identified by somepassword;

[b]Listener problem while configuring host string through NET config[/b]

Hi,
I am unable to create host string through Net config. While testing with userid/password, the test does not succeed.
The host string configured is known as PROCESS.
Net config error message while testing the connection is as follows:
"Connecting...ORA-12541: TNS:no listener
The test did not succeed.

Did you check that the DB is up ? If not, then check it and, eventually, start it up.
If yes, then open a DOS window, set your ORACLE_SID, connect to Sqlplus as sysdba and type :
SQL> show parameter service
what is the result ?

Problem with host string

hi
i am new here
2 days ago i was finish my database administrator course.-it mean that is the first course from 6(as much i know)
first you should know that english is not my lang so if i will maskes i am sorry
anyway after i am talking about me i will talk about my problem
i am trying to connect to sqlplus
after i click on this tool i get
user name:
pass:
host string:
i know that i need to go to the file tnsnames.ora and take from there the host string
i did that and after the parameter "host=" i saw the host string name.
after i did that i tried to connect with sysdba but without pass cuase if i conn with sysdba i dont need pass
in "host string " i write the host string accurding to the tnsnames.ora ang it doesn't work
as aresult i get a line that ask me the pass what sould i do?
tasks to all of you![b]

"Host string" entry to connect through SQL*Plus is the SID entry from the tnsnames. Not the parameter host=...
This is the first parameter, something else like the following :
DEMO92 =
(DESCRIPTION =
(ADDRESS_LIST =...The host which you said is the hostname which is the host of the database, not thedatabase itself.

Please check your tnsnames.ora file in your oracle_home->network->admin folder.
