Connect to Oracle 7.2.3 database

Hi,
Is there a tool (like SQL Plus, SQL Developer, ...) that can connect to a Oracle Database 7.2.3.
Because with SQL plus 10g en SQL Developer it isn't possible...

Davy,
The problem is not the tool, but the Required Support Files. All tools, whether sql*plus or whatever, need the Required Support Files.
The Required Support Files contain sqlnet, and no currently supported version will work with the version you mentioned.
That said, Oracle 7.2.3 was desupported prior to 1998, so thirteen years ago.
The only thing you can do is, provided you have a Metalink Support Contract, raise an SR, and order the 7.2.3 client.
Otherwise no joy.
You might consider to put the server with the database in a museum exposition.

Unable to connect to oracle 8i

Hi there,
I have been trying to connect to oracle 8i.

I have browse through the forum. There are people who encounter the same error as me. However, none of the replies provided a workable solution.
Should anyone happen to have any idea, what the error is about, pls help me. Thanks in advance.

Check to make sure that the SID specified is correct.
The SIDs that are currently registered with the listener can be obtained by
typing "LSNRCTL SERVICES ". These SIDs correspond to
SID_NAMEs in TNSNAMES.ORA, or db_names in INIT.ORA.
*Comment: This error will be returned if the database instance has not
registered with the listener; the instance may need to be started.

How to connect to Oracle 11gR2 from CF9

Hi,
how to connect to Oracle 11gR2 64 bit Database from CF9?
In CF Administrator no Oracle Driver is available.
Do I have to install Oracle Client Software on Server Hardware where CF9 Server is installed?
If yes, is Oracle Instant Client is enough or do I have to install full oracle client?
Any idea?
regards Claudia

Excellent, glad to hear it's sorted. Just be careful if you use any of the "advanced" features such as returning querysets from stored procedures or BLOBs, apparently there are differences between the JDBC and full DataDirect drivers in those cases.
However in 99% of cases you won't notice the difference.

Not able to connect remote oracle database over VPN

I can not connect remote oracle database over VPN. tnsping is ok and it shows the server information of remote database. i can also telnet the 1521 port of remote database server. I can connect the same server when it is located in the same LAN. Please help me out this is very urgent.

First, this is a forum of volunteers. There is no "urgent" here.
"Urgent" means one of two things -
1) people are dying, or
2) you have a customer-facing, revenue-producing production system that is down.
(And to get some perspective on the second case, keep the first in mind.)
For the first, you call whatever civil emergency service seems appropriate.
For the second, you open an SR with Oracle - which requires a paid-up support contract. For *them* to consider your problem "urgent", you will need to demonstrate that your problem falls under item #2. I seriously doubt your problem fits that criteria.
You don't have a support contract? Now you know the exact dollar figure that your company places on the data.
That said, you need to understand a few things about your specific problem,
First, port 1521 is only used by the listener to accept a connection request. Once it gets that request (and finds that it is for a service (sid) that it knows about, it will fork a server process and tell the requesting client that it can communicate with that server process over some other port .. a randomly chosen port number in the "high" range. It could be your vpn is blocking that other port, whereas your internal firewall is not.
But this is just an educated guess since I cannot find "can not connect remote oracle database over VPN" in any error message manual. If you had mentioned the VPN along with an actual oracle error message we could be much more precise in our diagnoses and recommendations.
---- edit 22 Sep
It occurred to me that I just assumed you were using the same client machine in both cases ... a laptop that you use both at work (local network) and home (vpn). If that assumption is false, there are probably problems with your tns setup on the home (vpn) machine.
But again, it would be much easier to help if you gave us an actual error message.

Help needed in connecting to oracle database in unity

Hi,
I have been trying to connect to Oracle database in my codes. I have tried using OdbcConnection and OleDbconnection. But both did not allowed me to connect to the database. The database, testDb, can be accessed using SQL plus as well as the SQL developer. I even tested the connection successful using ODBC data source administrator.
the following is my code for the connection string:
OdbcConnection connectionString = "Driver={Oracle ODBC Driver};Server=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP )(HOST=127.0.0.1)(PORT=1521))(CONNECT_DATA=(SID=Te stDb)));Uid=scott;Pwd=password;";
the error i got is [ODBC Driver Manager] Data Source name not found and no default driver specified.
for the driver parameter, i have tried using "Microsoft ODBC for Oracle". It gives me another error stating that the oracle and network components are not installed.
I even tried "Oracle in OraDb11g_home1" which was specified in the ODBC Data Source Administrator. The same error came out.
Below are some of my specifications:
Platform: Windows 7 64bit
Oracle: Oracle Database 11g Release 2 (64bit)
Unity: 4.1.2
Can someone please help me with this? What is it that i have done wrong?
Thanks.

whenever localhost (127.0.0.1) is used, this means that no remote client can ever connect to this system
The problem involves ODBC configuration & has nothing to do with Oracle.

Unable to connect to oracle database 10.1.0.2.0 from jdeveloper 11.1.2.1.0

Hello,
I am trying to connect to oracle database 10.1.0.2.0 from jdeveloper 11.1.2.1.0 to develop an ADF application.
But it is giving me the error
Test failed: Listener refused the connection with the following error:

I am able to connect to the database using SQL*Plus with the same credentials.
Any help is appreciated!

I take it you solved this problem, since you posted this: installing Oracle 10.1.0.2.0 (32 bit) on windows 2003 server

SAP MDM Import Manager connect to Oracle Database.

Hi expert,
I try to connect to Oracle DB with SAP MDM Import Manager but I cant.
I entered property in "Connect to Sorce" window.
============================================
Type : Oracle
Remote system : MDM
DBMS server : <DBMS host>:<listener port>
Database : Oracle_SID
User : Oracle database user
Password : Oracle database user password
============================================
then error ocurred.
"Unable to connect to source"
I aleady checked to connect to the Oracle database with Oracle client.
It is connected well.
How can I connect ??
thanks and regards
jun

Hi all,
thank you for your replies.
I tried to connect oracle DB except "< and >" symbol but It did not work.
I installed windowXP 32bit , Oracle client 32bit and SAP MDM Import manager 32bit in My local PC.
Also I connect to MDM DB using sqlplus in My local PC.
I wonder that TNSNAME.ORA is used DB connection using SAP MDM Import manager ??
I think TNSNAME.ORA is not used when I connect to DB using SAP MDM Import manager because I enter parameters are properties of TNSNAME.ORA.
I don`t know why don`t connect to DB.

Cannot establish connection with Oracle database

Hello
This is the first time I use BOE server with Crystal Report to execute some tests, and one issue is blocking me now, and I am not even sure if this is the right Forum where I should post it.
I installed BOE server XI 3.1 SP4 on Linux machine (new installation), and then I uploaded some existing Crystal Report templates that are working fine on another BOE server. Those CR templates have to establish a connection with a remote Oracle database to get the data, and we pass all credentials for this purpose.
The first time I run my first test I received this error that I could not find anywhere on the web :
ErrorLog 2011 8 10 7:05:52.505 14215 356 (Administrator:82) (../reporthandler.cpp:12462): CReportHandler::buildReportViewerError: CSResultExceFailed to open the connection." FileName:"../reporthandler.cpp" LineNum:12458 ErrorCode:756 ErrorMsg:"Failed to open the connection.
{FBAD55EE-BEAF-11E0-BC1C-005056813A72}.rpt" DetailedErrorMsg:""
I believe that the CR was not able to establish the connection with Oracle, so I install Oracle Client on the same machine (test remote connection ==> pass), I set the ORACLE_HOME variable, and I edit the file <installation_home>/ bobje/java/CRConfig.xml to add the path to ojdbc14.jar, and finnaly restart the tomcat server. However I am still getting the same error message.
Is there any hint that can help me troubleshooting this issue?
Thank you

do the reports use native oracle connectivity or JDBC ?
what version of Oracle client did you install ?
was it 32bit or 64bit client ?
what your LD_LIBRARY_PATH variable set to ?
what does it say in the CMC when you look at CR report's DB properties ?

Need help connecting to Oracle to create database

Am student taking DBA course; have altered pfile so that path shows where createdb is located. Cannot connect to Oracle; keep getting message "insufficient privileges." Createdb file amended per book to "REMOTE_LOGIN_PASWORDFILE=exclusive" and still can't connect. Can I grant connect privileges to internal/oracle? Tried several times to create database and am now using new database name to try again, but when I get to svrmgrl and type in "connect internal" and give password "oracle" as book says to do I get the "insufficient privileges" message again. Need help.

Linda,
when you use exclusive in remote_login_passwordfile is necessary make one file. Use the following instructions:
orapw file=orapw<SID> password=<password> entries=<users>
where
file=name of password file (mandatory)
password=password for SYS and INTERNAL (mandatory)
entries=maximum number of distinct DBA and OPERs (opt)
There are no spaces around the equal to (=) character.
Find orapwd.exe by Windows Explorer
Bye,

ODI topology connection error - oracle database

Hi,
I'm trying to connect to oracle database installed on a remote server through odi client installed on my windows machine. Oracle db is on RHEL 64 bit, I believe. I know the connection details such as hostname, sid etc but i'm not able to establish a connection using the oracle jdbc driver. I can perfectly connect to the db via sqldeveloper using tnsnames and also basic connection which rules out the possibility that i might be giving incorrect SID name in ODI connection since I'm using the same details for both

tnsping works fine. To solve the problem, I changed my JDBC connection string to another format which uses connect description with service name and that solved the problem. This is what I used.
jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on) (ADDRESS=(PROTOCOL=TCP)(HOST=) (PORT=1521)) (ADDRESS=(PROTOCOL=TCP)(HOST=) (PORT=1521)) (CONNECT_DATA=(SERVICE_NAME=)))
