Database Access Error - Listener Refused Connection With ORA-12505 - TNS?
Jul 29, 2013
I am using oracle 11g client library on Linux 64bit machine and trying to connect to oracle database using jdbc thin driver.The url format what I am trying to use is:
jdbc:oracle:thin:@IP address:port:service_nameWhen service_name = orcl :
I am able to connect with the above syntax. But when the service_name is having . e.g service_name = orcl.177.39.45, with the above format I get the above error.
If I change the URL syntax to following, it works
jdbc:oracle:thin:@IP address:port/service_name
But both seems to be valid syntax.So I would like to undestand the reason behind the same. When service_name is having ".", why ":" does not work and "/" works and when the service_name is without " ." , 1st format works. Is there any specific reason behind same?

ODBC--call failed.TNS:listener was not given the SID in CONNECT_DATA (#12504)
TNSname sets the SID. SQL*Plus is able to connect from the client Windows XP Proff using the same name. Access, on the same client, uses the same Oracle driver to connect successfully to other Oracle databases. These other databases show equal tnsname (different name and SID...)
ODBC Data Source Administrator configures the database and the test connection is successful.
Cannot set up a link from Access to the Oracle database. At some point, I have created a new Access database and it did let me connect, view the list of tables, and set up links to several tables, but the next day I could not open any of the tables and the complain was: ODBC--connection to 'MYDB' failed.
It seems that SQL*Plus passes correctly the SID from the TNSname but ODBC, when invoked from Access, does not. Yet, ODBC does it right for other databases.

I am running ORACLE 10.2.0 on Windows Virtual PC. System: Microsoft Windows XP SP3.
Yesterday I wanted to make a copy of my Virtual Machine Hard Drive Image. I directly copied all the files to my external hard drive, but I forgot shutting down my virtual machine when I was doing this.
Today I found my instance failed startup.
In OEM, it is showing:

We have an issue regarding OS level authentication to access Oracle 11gR2(11.2.0.1) database.
Our environment -
UNIX - AIX 5.3 (OS user id password is having kerberos security).
Oracle 11.2.0.1 (32 bit client) installed in server 1
Oracle 11.2.0.1 (64 bit server) installed in server 2.
Everything works fine when we created a general userid test_db in the database and connect through sqlplus test_db@dbname.
But when we try to use the option of OS level authentication using "sqlplus /", it throws following error and could not be connected.
ERROR: ORA-12545: Connect failed because target host or object does not exist
I have created the same OS user name in database (with external password authentication) with prefix OPS$. we have set ORACLE_SID as well.

From doc. I see that the "current" is the number of client connections it is handling, that is, its current load.It is not correlating with the sessions or processes in DB, so what does this means?
Does it show that more than 150 connections try to perform connection simultaneously?

I have a DB on my local machine and it was working fine till yesterday.Today suddenly I started receiving error "IO Error : The Network Adapter Could not establish the connection".
1) My first question is that is there some log entry corresponding to this failed connection attempt in listener.log or alert.log ? If yes, how to identify it ?
2) My second question is : What to deduct from listener logs pasted below?I know about "service_update" messages, but what about others (having CONNECT_DATA in them) ? Also, what is "WARNING: Subscription for node down event still pending" in below logs ?

I'm setting up APEX REST security by following the instructions from [URL]...Everything works great according to document.
I can acquire a token, then passing it in the header to get needed data from REST service. Consumer acquires an token by going on web browser to [URL]...
It will be redirected to[URL]... asking for username and password on browser. Once entering them correctly, it will be directed to Redirect URI defined in the OAuth2 client with the token in the URL.
My question is that is it possible to do token acquiring by coding (like in Salesforce) without going to web browser? We've tried doing that, it will stop due to redirect to sign-on.

I have a client program that needs to communicate with another server program. My client program is implemented in PL/SQL using utl_tcp running on Oracle 9 while the server program is a 3rd party software running on Windows server 2003.
Basically my client program needs to send a request to the server, waits for the response (wait for the incoming string which ended /w chr(3) ) and then acknowledge (sending chr(6) ).
My problem is that if I wait for the chr(3) and then acknowledge. My send routine (l_sent := utl_tcp.write_text (g_conn, p_content) will raise a Oracle generic network error. It seems like the connection is closed. I checked /w the vendor and they said it might be I am taking too long to response ( I question timeout is the problem). I have also attempted to change my read routine from read_line to read_raw but it only make things worst. I cannot even read the complete string. At least with read_line, I can read back the entire string.
My current work around is to send out the ack before I receive the chr(3) (which is not recommended by our vendor).
