XCode: invalid host string: 'localhost'

Hey! I'm trying to compile some C++ code in XCode. I'm getting this error: invalid host string: 'localhost'
So I searched on the web. I found it was probably in error in hosts, so I checked it. But, my hosts was perfect! Nothing wrong with it! Here's my hosts file:
# Host Database
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
127.0.0.1       localhost
255.255.255.255 broadcasthost
::1             localhost
fe80::1%lo0     localhost
Yup.

I was running against the same problem on a run-time of xcode debug. Are you running gas mask? If so, I was simply under the remote file rather than the local in my settings.

Invalide connect string

Hi
While making a connection to OLite database i gave the url as
" jdbc:polite4@localhost:100:orabpel" and the same is available in oc4j-ra.xml file as connection string but while testing connection it displays the error message as
Internal error : invalid connection string. please advice
thanks
partha

This is the connect string I have which works:
"jdbc:polite4@localhost:100:orabpel"
using driver class
"oracle.lite.poljdbc.POLJDBCDriver"
I notice you have a leading space in the url you quote in your post, is this causing the problem?

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.

Changing the Host String in Oracle 10.2.0.4

Delphi 3 or Delphi XE gives Invalid class string error

I have Delphi 3 and a runtime error occurs when I RUN this project. No build errors...
The form appears correctly and I put the path to the GroupWise domain directory :
F:\opt\novell\groupwise\mail\dom1
I click on the CONNECT button and the error is :
"Project admin_api.exe raised an exception class EOleSysError with message 'Invalid class string'. Process stopped. Use Step or Run to Continue"
For Delphi XE the error is only "Invalid class string".
What am I doing wrong ?

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;

Host String

I've installed Oracle Forms 6i includingSQL Plus 8.0 on Win2000 server. no problem with user name and password but no Host string seems to work. Error message ORA-12203: TNS unable to connect.

[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:

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 :

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.

Hi,
Host is the address of the server.
Please check your tnsnames.ora file in your oracle_home->network->admin folder.
there you will find something as
HOST =Twinkle

Report failed to parse SQL query:ORA-01745: invalid host/bind variable name

Hi,
We are currently upgrading from v2.2.0.00.32 to v4.0.0.00.46.
I have copied the applications onto our test server along with the various database objects and data etc.
When I am running a report in v4, it is failing with the following error: "failed to parse SQL query: ORA-01745: invalid host/bind variable name".
When I copy the SQL that builds the report into TOAD (on out test server) it runs OK so really cant see why it would fail in APEX. It works fine when I run the query in our APEX v2 and in TOAD in our live server.
The query is as follows:
SELECT
aea.ALTERATION_ID
,aea.ALTERATION_ID "ALTERATION_ID_DISPLAY"
,aea.assembly_name "Revised BOM"
,assembly.description "Revised BOM Description"
,assembly.INVENTORY_ITEM_STATUS_CODE "Revised BOM Status"
,aea.BEFORE_CHANGE_QTY
,flv.MEANING "Alteration Type"
,aea.component_name "Part No"
,component.description "Part No Description"
,component.INVENTORY_ITEM_STATUS_CODE "Part No Status"
,aea.AFTER_CHANGE_QTY
,TO_CHAR(aea.last_update_date,'DD-MM-YYYY HH24:MI:SS')"Last Update Date"
,aea.LAST_UPDATE_BY
,aea.COMMENTS
,aea.ORACLE_CHANGE_NOTICE
,AEA.SELECTION_CRITERIA
FROM XXMEL_APEX_ECO_ALTERATIONS aea
, fnd_lookup_values flv
, (SELECT INVENTORY_ITEM_STATUS_CODE
,segment1
,description
FROM mtl_system_items_b
WHERE 1=1
AND organization_id = 26) component
, (SELECT INVENTORY_ITEM_STATUS_CODE
,segment1
,description
FROM mtl_system_items_b
WHERE 1=1
AND organization_id = 26) assembly
WHERE 1=1
AND aea.COMPONENT_NAME = component.segment1 (+)
AND aea.assembly_NAME = assembly.segment1 (+)
AND flv.lookup_code = aea.acd_type
AND aea.eco = :P13_ECO
AND flv.lookup_type = 'ECG_ACTION'
AND modify_flag = 'Y'
ANy help would be great,
Thanks
Chris

For some reason, the updatable fields (this is a updateable report) where not connecting to the database properly. Whn I changed them to a report columns and removed the database field reference, the report rendered

XCode: invalid host string: 'localhost'
