I am building the Oracle on RHEL 5(on Virtual machine with fixed disk space). I could install, after configuring and tried to connect to the database using "sqlplus system" on the command prompt(logged in as root), I get the following error message:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux Error: 2: No such file or directory
connecting two oracle database in two different server.I installed Oracle 10g XE in both system.Both system act as Server.I need to connect both server using database link concept.
how to use the tnsnames,ora and listener.ora file for connecting both system.
I'm using following connection string: +connectionString="Driver={Oracle ODBC Driver};Server=someDb;Uid=useruidr;Pwd=password"+
when I call method "Open" on "OdbConnection" I get following exception: +ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified+
"someDb" is specified correctly in tsnames.ora,
"...client" and "...clientin" are added to PATH environmental variable
ORACLE_HOME is set to "...client"
I have Oracle Client 11.2.0.3.0 installed
Operating system is Windows 7 32 bit
When I change Driver to "Microsoft ODBC for Oracle" it works fine. However I want to use Oracle ODBC Driver.
Connecting Oracle to SQL Server via database link.
I am trying to connect from Oracle 10G to a SQL Server database. I have looked at the manual and i will admit that i am finding the documentation quite difficult to follow. There seems to be several options to use but none of the documentation describe how each option works.
As an example, i have been given the following information on the database i need to connect to (i.e. the SQL Server database)
- Username
- Password
- Database Name [lets assume the database name is data_extract]
To connect the above i made the following changes
$ORACLE_HOME/hs/admin/inithsodbc.ora
---------------------------------------
HS_FDS_CONNECT_INFO = data_extract
HS_FDS_TRACE_LEVEL = 0
$ORACLE_HOME/network/admin/tnsnames.ora
---------------------------------------
sqlserver.db =
(DESCRIPTION =
[code]....
Note: In listener.ora, i only added the last SID_DESC entry. I then went on and created the database link as shown below
create database link sqlservdb using 'sqlserver.db';
When i try to access a table i get the following error
sqlplus> select * from TESTTABLE@sqlservdb;
select * from TESTTABLE@sqlservdb
*
ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from ORASQLSERVER
A couple of things i am not sure of:
- Where do i specify the username and password to access the sql server from the oracle db to the sql server db
- Having read around on the internet, i can see some people refering to a DSN datasource. I am told that the information that i have is all i need. Is this correct or do i need something else?
- The sid i specified in inithsodbc.ora and tnsnames.ora is actually the sql server database. Is this correct?
connecting to an oracle db with the instant client 11.01.06. I can connect to the db via other tools like sqldbx or SqlTools 1.5 which are also using oci. So now I tried it with c++ using Visual Studio 2005 SP1.
First I tried this
Environment* env=Environment::createEnvironment(Environment::DEFAULT);
Connection* con=NULL;
try{
con=env->createConnection("user","pwd","//servername:ip/mydb");
}
and got following error: "the attribute OCI_ATTR_USERNAME is greater than the maximum allowable length of 255".
So I tried:
Environment* env=Environment::createEnvironment(Environment::DEFAULT);
Connection* con=NULL;
try{
con=env->createConnection("user","pwd","tnsservice-name");
}
where tnsservice-name is the name I specified in the tnsnams.ora, and which I used with the other tools working fine -> same error.My username is only 4 long, so I thought it might have something to do with the string. So I tried:
Environment* env=Environment::createEnvironment(Environment::DEFAULT);
Connection* con=NULL;
string user="user";
string passwd="pwd";
string db="tnsservice-name";
try{
con=env->createConnection(user,passwd,db);
AfxMessageBox("sucess");
}
now it returned the error "TNS:connect descriptor too long". Can't have anything to do with the .ora file, since it worked fine for the other tools. Plus it didn't matter if I renamed the .ora file or removed it from the TNS_ADMIN directory..So I searched a little more for a solution and so an example, where the the last argument is missing. So I tried
string user="user";
string pwd="pwd";
Environment* env=Environment::createEnvironment(Environment::DEFAULT);
Connection* con=NULL;
try{
con=env->createConnection(user,pwd);
}
It returns: "TNS: protocol Adapter error" which I somehow can understand, since the adapter doesn't know to wich db to connect.I also tried to use some frameworks like soci or otl but was never able to compile them... (link errors, unknown data types etc...).

I don't believe it is using the TNSNAMES.ora entry for this, because when I take it out of there it still connects. I create a 10.1.0.5 database and copied the tables,etc to there. But I'm having problem connecting, getting "ORA-12154:TNS Could not resolve service name". Tried the following:

I did add the entry for the 10G database to TNSNAMES.ora:
NJZTEST =

(CONNECT_DATA =

I new to this, but my guess is the other entry had the full path name..and this SERVICE_NAME does not. But then again I don't believe it looks at the TNSNAMES file. This NJZTEST is the 2nd instance on the NJZAINETTEST machine.
We have a requirement to connect from 9.2.0.8 database on AIX to MS SQL 2008R2 .

OS : Windows 2008 (64-bit)
1] Can we use - Database Gateway for SQL Server for the above set up ? If so , does this require a separate license ?
2] Where Do we need to install the "Database Gateway for SQL Server " -- soruce or target server ?
3] Is there any other solution apart from using "Database Gateway for SQL Server " ?
We've got a 32 bit .Net windows application which uses ODAC 10g (1.x) to connect to a 10g database on the backend. Things work fine in this deployment.
We're in the process of setting up a new development machine. This machine has ORACLE 11g (64 bit) installed on it. We're running into issues connecting the the database.
This is the code block we're using to connect to the database:
=======================================
string dataString = "user id=xxx;password="xxx";data source=localhost:1521/ORCL";
using (OracleConnection oraconn = new OracleConnection(dataConn))
{
oraconn.Open();
Oracle.DataAccess.Client.OracleCommand cmd = new OracleCommand(sOraSQL, oraconn);
[code]........
We get an exception on the "oraconn.Open()" command.
The output window in VS2010 shows this:
-----------------------------------------------------------
A first chance exception of type 'Oracle.DataAccess.Client.OracleException' occurred in Oracle.DataAccess.dll
The oraconn variable looks like:
-------------------------------------------
- oraconn {Oracle.DataAccess.Client.OracleConnection} Oracle.DataAccess.Client.OracleConnection
+ base {Oracle.DataAccess.Client.OracleConnection} System.ComponentModel.Component {Oracle.DataAccess.Client.OracleConnection}
ConnectionString "user id=xxxxx;password="xxxxxx";data source=localhost:1521/ORCL" string
ConnectionTimeout 15 int
DataSource "localhost:1521/ORCL" string
[code]........
The details of the exception are:
---------------------------------------------
- ex {""} System.Exception {Oracle.DataAccess.Client.OracleException}
+ [Oracle.DataAccess.Client.OracleException] {""} Oracle.DataAccess.Client.OracleException
+ Data {System.Collections.ListDictionaryInternal} System.Collections.IDictionary {System.Collections.ListDictionaryInternal}
HelpLink null string
[code].........
To reiterate, in our original deployment (10g database with 10g (1.x) ODAC, we can connect fine with the database. It's with the new setup (11g database with 10g(1.x) ODAC) that we are having issues. We've previously been able to deploy on client machines which were using ORACLE 11g. To accomplish this, we had to make sure that the password was inclosed in quotes (").
What is going on here? What should we be looking at? How do we go about debugging fixing this?

I want to know if it is possible, to run IMP program without connecting with database user , for example :

I checked lots of pages but I'm not able to find a solution für my problem. I already set up a primary and a standby database (prim = ALPHA1 / standby = ALPHA2). After enabling my dgmgrl configuration I got two errors:
DGM-17016: failed to retrieve status for database "alpha2"

View 8 Replies View RelatedI'm trying to make a connection to sql server from an ORACLE 8.0.4 (I know, it's ancient) but can't seem to get it to work. I've read a lot of articles on the internet regarding the Heterogeneous Services but just can't get it to work on my system. Therefor I tried an example on connecting to an Excel workbook I found on another forum [URL] but that gives me the same problem as with connecting to sql server.
Here is what I've got:

One thing I noticed is that I do not have an hsodbc.exe file in my \bin, should it be there?
(I also tried Tgmsql80 in stead of hsodbc as program in Listener, resulting in an extended time of testing the connectivity but with the same result)
Is there any way I can test parts of the connection to limit the location of the problem? (e.g. does the listener get to the TNS)

I have been trying to connect to an remote oracle db from c# .Net . I believe I have the proper code (Cos when the user id and password strings were omitted , it threw an error of invalid user Id and password).
Once this was properly provided , the connection is now throwing "TNS Error : No Listener " error . The same remote DB is perfectly connecting through TOAD and it is from the tnsnames.ora file of the local file that i got the connection string from . Hence , I don't thing its a problems with that as well.
I am trying to learn Oracle and trying to use Visual Basic 7 to connect to an Oracle database, upload a text file to an empty table and then update a second Oracle table based on the info in the first table. I know you can do this with SQL*Loader, but how about VB? I did some research and found this posting: Re: Using Bulk insert or SQL Loader in VB6 I borrowed the code from there and altered it for my application (see below).
Dim con As New ADODB.ConnectionDim rst As New ADODB.RecordsetDim rst2 As New ADODB.RecordsetDim rst3 As New ADODB.Recordset con.ConnectionString = "Provider=OracleDB;User ID=john;Password=doe;Data Source=TestDB;"con.Open 'open the text filerst.Open "C:OracleTestCombinedCombined.txt" 'rst2 is an empty recordset because TempTable is empty at this time.rst2.Open "select * from TempTable", con, adOpenDynamic, adLockOptimistic 'adding rows into TempTable.Do Until rst.EOFrst2.AddNew Array("PACKET", "DATERET"), Array(rst.Fields("PACKET"), rst.Fields("DATERET"))rst.MoveNextLoop rst.Closerst2.Closecon.Close
My second question is this - say I had a second Oracle table in the same DB called "MasterTable", with the same two fields as "TempTable" (PACKET and DATERET). I want to update the DATERET field in "MasterTable" with the DATERET field in "TempTable" ONLY when the "PACKET" field matches in both tables.
