Ok, for your listener.ora file, above you have the SID_LIST and the LISTENER sections. But what is this that follows, below?

which is working file
but i have an problem in my tnsname.ora file

Error handler for ORA-29283 - not working

I am running Oracle 9.2.0.4 on HP-UX.
I have a stored procedure which reads a text file. I have set up an execption for error code ORA-29283 (invalid file operation). When I test my procedure (by not having the file to read) my exception handler is bypassed for a general exception error and my procedure terminates.
here's parts of my code:
Declare
file_not_found EXCEPTION;
PRAGMA EXCEPTION_INIT (file_not_found, -29283);
BEGIN
nochourly_file := UTIL_FILE.fopen('/mydirectory','myfile.txt','R');
Loop
begin
UTL_FILE.get_line(nochourly_file, sbuffer);
EXCEPTION
WHEN NO_DATA_FOUND
THEN
GOTO end_of_file;
WHEN file_not_found
THEN
DBMS_OUTPUT.put_line ('Invalid File Operation - file not found');
skip_last_hour_processed;
GOTO end_of_file;
WHEN OTHERS
THEN
err_num := SQLCODE;
err_msg := SUBSTR (SQLERRM, 1, 100);
DBMS_OUTPUT.put_line ('Error ' || TO_CHAR (err_num));
DBMS_OUTPUT.put_line (err_msg);
DBMS_OUTPUT.put_line (sbuffer);
RAISE;
EXIT;
END;
===============
When this fails I expect to see the message
"Invalid file operation - file not found"
which indicates my exception handler was processed.
Instead I see:
SQL> @$HOME/newhourly_dly

Can you explain:
1) what generated the error message since
a. it wasn't my exception handler and
b. it wasn't the "WHEN OTHERS"
2) Why isn't my error handler working?
Please advise.
Thank you

Hello
Not sure why your exception is being ignored but usually, to be able to handle the UTL_FILE exceptions, you need to explicitly code for each exception declared in the UTL_FILE package i.e.
EXCEPTION
      WHEN utl_file.invalid_path THEN
             --Do something
      WHEN utl_file.invalid_mode THEN
             --Do something
      WHEN utl_file.invalid_filehandle THEN
             --Do something
      WHEN utl_file.invalid_operation THEN
             --Do something
      WHEN utl_file.read_error THEN
             --Do something
      WHEN utl_file.write_error THEN
             --Do something
      WHEN utl_file.internal_error THEN
             --Do something
END;HTH

but i am not able to connect to oracle as hr/hr@PROD
i have set
alter system set service_names='DEV.haunting.com scope' scope=both;

Missing alias of tnsnames.ora

today i discovered a problem with my tnsnames.ora file.
With my free old Toad, there is no way to define the "name" of the connection. I only have the network alias and the user. So i used alias names like customer-project(PRODUCTION) and customer-project(DEVELOPMENT) for old oracle 8i connections, where i can not use SQLDeveloper. What a bad idea...
Tnsping and SQL*Plus work fine, Toad works fine, but SQLDeveloper has a problem. Many (random?) network aliases are missing.
In the future i will avoid special characters in my network aliases, but its intersting to know that the common way to use tnsping to test tnsnames.ora will not be significant in combination with SQLDeveloper.

So the problem with SQL Developer is that it stops reading the tnsadmin.ora file when it gets to one of these tns aliases with ()s.
I was able to confirm this with 3.0EA1, trying both TEST(1) and "TEST(1)", and probably most significantly in being able to identify this, no error is reported in the UI, the console or the Loggnig Pane (even with logging set to finest).
However, I was unable to use either form of tns alias with ()s with either tnsping or sql*plus, which is what I thought you were saying worked for you. Unlike SQL Developer, though, I was able to use tnsping and sql*plus with tns aliases defined after the tns alias with ()s.
Your workaround of moving the tns aliases with ()s to the bottom of the file would avoid the problem in SQL Developer, but I would think it would be best if SQL Developer actually reported a warning/error in some way when it finds a tns alias it cannot interpret.

Developing without Full client / tnsnames.ora

I am trying to develop an OCI application using Borland C++ Builder. I want to deploy and develop using Instant Client 10G without tnsnames.ora file. I have 2 PCs - NT4 & XP.
On the NT4 PC I had installed the full Oracle Client and was using the tnsnames.ora file and things were working fine. I've since uninstalled the full client and am now getting the "ORA-12154: TNS:could not resolve the connect identifier specified" error (using Instant Client)
The XP box has never had the full client installed, does not have a tnsnames.ora file but works fine using the same code.
I've been looking through this forum and note Justin Cave's comments that you can deploy but not develop using Instant Client but this seems to work fine on my XP box. (I am an Oracle novice so I could be missing something here).
I have also checked the FAQ on connection strings and think I have got that correct (same code works on 1 PC and not the other) and don't think I've set the enviroment variables TNS_ADMIN or ORACLE_HOME on either machine.

Hrm, interesting. It always used to be DBQ but it seems it might have changed to SERVER at some point.
Anyway, I tried this and it worked fine for me (using 10204)

Note also that unless you really want to create a file dsn, you could also just use a dsnless connection string and pass that directly too:
set con = createobject("adodb.connection")
con.open "driver={Oracle in OraDb10g_home1};uid=scott;pwd=tiger;server=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=gdarling-pc2)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=orcl)))"

Using tnsnames.ora

Where can I ask a questio about OCI?
I want to make a connection using tnsname.ora except using a dblink and username and password whit oci. I used this code up to know :
OCIInitialize((ub4)mode, (dvoid *)0,
(dvoid*(*)(dvoid *ctxp, size_t size))0,
(dvoid*(*)(dvoid ctxp, dvoid memptr, size_t newsize))0,
(dvoid (*)(dvoid ctxp, dvoid memptr))0);
OCIEnvInit(&envhp, (ub4)OCI_DEFAULT, (size_t)0, (void**)0);
OCIHandleAlloc((dvoid*)envhp, (dvoid**)&errhp, (ub4)OCI_HTYPE_ERROR,
(size_t)0, (dvoid**)0),"");
OCIHandleAlloc((dvoid*)envhp, (dvoid**)&srvhp, (ub4)OCI_HTYPE_SERVER,
(size_t)0, (dvoid**)0);
OCIServerAttach(srvhp, errhp, (text*)dblink, (sb4)strlen(dblink), (ub4)OCI_DEFAULT);
OCIHandleAlloc((dvoid*)envhp, (dvoid**)&svchp, (ub4)OCI_HTYPE_SVCCTX,
(size_t)0, (dvoid**)0);
OCIAttrSet((dvoid*)svchp, (ub4)OCI_HTYPE_SVCCTX, (dvoid*)srvhp, (ub4)0,
(ub4)OCI_ATTR_SERVER, errhp);
OCIHandleAlloc((dvoid*)envhp, (dvoid**)&usrhp, (ub4)OCI_HTYPE_SESSION,
(size_t)0, (dvoid**)0);
OCIAttrSet((dvoid*)usrhp, (ub4)OCI_HTYPE_SESSION, (dvoid*)username,
(ub4)strlen(username), (ub4)OCI_ATTR_USERNAME, errhp);
OCIAttrSet((dvoid*)usrhp, (ub4)OCI_HTYPE_SESSION, (dvoid*)password,
(ub4)strlen(password), (ub4)OCI_ATTR_PASSWORD, errhp);
OCISessionBegin(svchp, errhp, usrhp, OCI_CRED_RDBMS,
OCI_DEFAULT);
But I want to change it in a way that I can use tnsnames.ora.

Do not pass the dblink parameter in your program, pass an empty string over there and if you are on a UNIX/LINUX set TWO_TASK to the tns alias, in your case if dblink was a valid tnx alias set TWO_TASK to dblink and run the program

Tnsnames.ora file does not seem to load in SQL Developer

I've really tried my best to figure this out on my own ... through the Help, this forum, and Internet in general. I apoligize in advance for having to ask this, since I'm sure this is a common issue. This particular form entry was really close:
Database Connections will not load tnsnames.ora
But, I just can seem to figure out why, or where entries from my tnsnames.ora file are loading into SQL Developer.
- I have the TNS_ADMIN system environment variable defined to the directory where tnsnames.ora is stored - C:\oracle\product\10.2.0\client_1\NETWORK\ADMIN.
- I do not see a TNS tab as the forum entry above indicates anywhere in SQL Developer - This may be my problem.
It seems that this issue could be cleared up with better directions on how to import tnsnames.ora entries into SQL Developer. Is there any specific direction on how to get your tnsnames.ora file setup correctly with SQL Developer running on Windows XP - Besides the Help which mentions the setup of TNS_ADMIN, but doesn't really tell you what the expected result is, or where the entries will be, or how to verify this is working?
Any help would be most appreciated.
Thanks,
Dave

Using Windows XP/Vista...
After testing in our environment, it appears that SQL Developer 1.5.1 (5440) does in fact ignore the TNS_ADMIN environment variable and ONLY looks in the Oracle Home directory (network/admin). We define a central network location for our tnsnames file and have the tns_admin setup to point there instead of locally for our users.
When selecting to add a new connection (in 1.5.1, it works in previously releases... meaning 1.2.something) and selecting TNS, the drop-down remains empty. However, if I exit SQL Developer and then copy the tnsnames file to the local network/admin directory I can then re-launch SQL Developer and the drop-down is populated. Exiting SQL Developer again, deleting the local copy of tnsnames, and then launching SQL Developer yet again results in the drop-down being empty.
All other Oracle-related applications function as expected (as they have for years) using the TNS_ADMIN environment variable.
Any suggestions/ideas?

Connection to db works with ezconnect but fails with tnsnames.ora

ERROR:
ORA-12154: TNS:could not resolve the connect identifier specifiedstates, in no uncertain terms, that the system can not find the @mrap in the TNS translation methods. Usually that indicates a problem in finding the correct entry in the correct tnsnames.ora file. Some related thoughts:
1) The LIST of methods allowed is found in SQLNET.ORA on the client. If multiple methods are in the list, the client will step through the methods.
It is possible that you do not have method calling the TNSNAMES.ORA file in the list. (You appear to have that.)
2) The mrap must be one of the entries on the left hand side of te equals sign of a stanza.
MRAP = (DESCRIPTION (appears to provide that)
3) The SQLNET.ORA could provide a 'default domain' to append on the end of the lookup value in TNSNAMES.ORA
Not sure whether your post of the sqlnet.ora selectred only a few lines or the entire file.
4) Variable issues can exist.
- The TNS_ADMIN variable may be used to force the use of a specific directory instead of %ORACLE_HOME%\network\admin .
- ORACLE_HOME can be adjusted by a variety of methods, and may be in both teh registry and the system environment

Connecting to a database that's not in tnsnames.ora

Hi there,
I'm using Oracle 8.1.6/Apache/PHP & would like to be able to connect to a database that's not listed in the local tnsnames.ora (by local, i mean the machine that's serving the web pages).
Is this possible?
Thanks!

I'm not sure that you can use this in PHP/Apache, but when I used Oracle Enterprise Manager (which isn't ported to Linux so I had to use a different machine (NT/Solaris)) I used the format ipaddress:port:SID (ex.: 192.168.0.5:1521:cddata), where ipaddress is the address of your machine, port is the port number of the listener on the database (defulat is 1521) and SID is the SID of the database you want to access.
I hope this helps.

SQL Developer is not able to identify the Tnsnames.ora file

Hi,
I have installed the following in the laptop having Win XP:
1) Oracle 10gR2 Client software in the D: drive of laptop. Tnsnames.ora is located in this clients Network\Admin path. This client is used to access the databases on the other servers.
2) Oracle 10gR2 Database software in the E: drive of laptop. Right now there is not Tnsnames.ora file in this softwares Network\Admin path. This db software has been installed to create local databases in the laptop.
3) Oracle SQL Developer Version 2.1.1.64 is also installed in C: drive of laptop.
The problem which now I'm facing is that the SQL Developer is not able to identify the Tnsnames.ora file mentioned in the above point-1 which contains entries of databases on the different servers. Could you please help me out in solving this problem?
Thanks in advance.
MAK

I forget what version I was using at the time, but when I had an ORACLE_HOME defined for the environment and TNSNAMES file defined in SQL Developer (different one than was in ORACLE_HOME), that I would see results from both tns files. I don't know if that is still the case. I have since dropped my ORACLE_HOME environmental variable.

ASM instance not shown in tnsnames.ora

Hi,
Currently I have an Oracle 11g database on linux with ASM installed, or at least that's what I can tell from querying v$logfile and v$datafile views. But in my tnsnames.ora and listner.ora I only see the db instance with no ASM instance. If I goto $ORACLE_BASE/admin, I see ASM and orcl. But under $ORACLE_BASE/admin/+ASM/pfile, I see no files.
This is a vm image by the way. The database is running fine as far as i can tell. My question is why there is no ASM entries in the above files?
Thanks for the help.

ASM instance is not used by applications users. It is used by Oracle which can see it, so you do not need any entry in tnsnames.ora for ASM instance. Also ASM instance usage init.ora file from $ORACLE_HOME/dbs directory, so you do not see any file in admin/pfile directory.

Toad with Oracle Instant Client 10.2.0.1.0(not able to locate tnsnames.ora

Hi,
I have both Oracle Client 9.2 and Instant Client 10.2.0.1.0 on my laptop. How to make Toad 8.5.1 locate tnsnames.ora file for instant client.
When I open Toad, and selects "Instant Client 10.2.0.1.0" as installed client, it shows the error message "tnsnames.ora not found!"
Below is the setting:
Instant Client - 10.2.0.1.0
ORACLE_HOME_NAME: C:\Program Files\PHP\
ORACLE_HOME: C:\Program Files\PHP\
ORACLE_SID:
NLS_LANG:

C:\Program Files\PHP\ exists.
C:\Program Files\PHP\ is in PATH.
Client DLL: C:\Program Files\PHP\oci.dll
Client Version: 10.2.0.1.0
Home is valid.
Thanks

Sal, your comment is pretty irrelevant to the question :^)
user570251, since you are restricted to using Windows, it will not be easy for you to use two different Oracle clients on the same machine.
Basically, you'll have to change TNS_ADMIN whenever you want to change between clients.
Why do you need two client versions on your computer?

Tnsnames.ora, sqlnet.ora & listener.ora files are not exit

DB version: 10.2
Hello All,
I just joined the project and notice tnsnames.ora, sqlnet.ora & listener.ora files are not exit under $ORACLE_HOME/network/admin.
But still we can connect to the database,
From command prompt or via enterprise manager studio from client site.
Any idea?
OR
what is the best way to create above files in the existing database?
DN

tnsnames.ora and sqlnet.ora are client side files, listener.ora and sqlnet.ora are server side files.
Listener.ora need not exist if using defaults and dynamic registration of services. It may be possible to cope without all those files, depending on the environment.
Is the database on the local or remote computer and how are you connecting (from sqlplus)?
Maybe you have a tnsnames.ora somwhere else? (Try using find command) Maybe TNS_ADMIN is set?

Ora:contains() does not work

Hi All,
Can not see why the following query yelds no result:
SQL> select e.extract('/experimentDocument/data/rawData/fileDscr/notes/HTML/
2 BODY/P/text()') from EXPDOC e where
3 existsNode(value(e),'/experimentDocument/data/rawData/fileDscr/notes/HTML/
4 BODY/P[ora:contains(.,"note")]','xmlns:ora="http://xmlns.oracle.com/xdb"')
5 =1;
no rows selected
The similar query works:
SQL> select e.extract('/experimentDocument/data/rawData/fileDscr/notes/HTML/
2 BODY/P/text()') from EXPDOC e where
3 existsNode(value(e),'/experimentDocument/data/rawData/fileDscr/notes/HTML/
4 BODY/P[contains(.,"note")]','xmlns:ora="http://xmlns.oracle.com/xdb"')
5 =1;
E.EXTRACT('/EXPERIMENTDOCUMENT/DATA/RAWDATA/FILEDSCR/NOTES/HTML/BODY/P/TEXT()')
There is "note" space available for each file description.
May be it's a privilege problem, because I can not see
DEFAULT_POLICY_ORACONTAINS policy. How to check whether this policy is accesseble?
Any help will be appreciated,
Boris

You use ora:contains with score.
Try 'ora:contains(text(),"note")>0' instead of
'ora:contains(.,"note")'.

We have checked, this is a known bug.Bug 4657820 - NLS:XENT10201-050913:FAIL TO INSTALL WINDOWS XE UNDER RUSSIAN LOCALE.
The simptom is that installation fails without error messages when the installation is performed under the following locale.
- Russian
- Estonian
- English - South Africa
- Spanish - Dominican Republic
The workaround is to change the user locale to something else before the XE installation.
