Connect from MS ODBC to Oracle RAC

I always connected to our Oracle 9i database using MS ODBC in Excel 2007and Access 2007.
We recently migrated to Oracle 11g RAC which has two nodes. Have no problem connecting using Oracle RAC string with SQL Developer and SQL Plus to the the Oracle RAC.
For the client ODBC I cant seem to connect using the RAC String. The MS ODBC Excel and Access prompt for username, password and host. In the host I put in the entire RAC String and it never connects showing TNS issues.
Please advise.

You can provide any one instance name instead of the RAC string name so it can establish the connection.
Example: Username/password@RACInstance1
or
username/password@RACInstance2

Huge number of idle connections from loopback ip on oracle RAC node

Hi,
We have a 2node 11gR2(11.2.0.3) oracle RAC node. We are seeing huge number of idle connection(more than 5000 in each node) on both the nodes and increasing day by day. All the idle connections are from VIP and loopback address(127.0.0.1.47971 )
netstat -an |grep -i idle|more
127.0.0.1.47971 Idle
any insight will be helpful.
The server is suffering memory issues occasionally (once in a month).

Migrating oracle 9i from Fail safe to Oracle RAC

We are planning to migrate our Oracle 9i database from Fail safe to Oracle RAC. Does anybody has any experience to share? Where can I find the documentation about this?
Regards
Tariq

FailSafe Cluster and RAC are completely different architectures, there's no direct migration path. Export the 9i database and import into a fresh RAC database.
At the same time move to 11gR2.

Steps to change universe database connection from SQL server to Oracle 10

Hi,
we are moving from sql server to Oracle 10.Please let me know the steps and various parameters I should consider while changing universe database connection from SQL server to Oracle 10.
Following are the steps which I assumed :
1.     create a new Oracle database connection or edit the existing connection to point to Oracle server
2.     Need to check sql for each object, having integrity check for universe will solve the purpose of parsing each object
3.     Exporting the universe after integrity check
4.     Report data testing
Let me know if I miss on any steps.Also what all factors I need to consider while moving to Oracle for eg: what @ custom sql,what @ table names,what @ LOV etc.
Kindly reply

Thanks Abhijeet and Shreyash,
I will follow the steps you have suggested.
Actually I was searching for this on net and got to know that with Oracle database connection,theres lot of stuff needs to take care of in terms of custom sql and LOV and in our case,we have lot of custom sql for each object in the universe so just wanted to confirm.
I will do the changes and let you guys know in case theres any isuue specifically to Oracle.

Reporting Services connections are getting dropped by Oracle RAC

My current customer is using Oracle RAC (11g) for their data store. They currently are using SQL Server Reporting Services to connect to it. We are experiencing an issue where the connection appears to be redirected at the server which causes the connection to be lost with the client.
I am curious if this is "by design" or if we need to review some configuration settings to better handle this.
We have 3 VIPs fronting the RAC and they are all specified in the TNSNAMES.ORA file.
Any feedback or input on this issue would be greatly appreciated.

Hi,
I suggest you look at:
http://www.oracle.com/technetwork/database/clustering/overview/awm11gr2-130711.pdf
and the similar paper from 11.1:
http://www.oracle.com/technetwork/database/clustering/overview/awmrac11g-133673.pdf
This explains the basic concept, of how clients should connect to the database, and probably clarifies your issue.
In generall Oracle will not redirect during runtime, only during connection time.
This however should not be of an issue, if you connect to a service. (You shouldn't connect to a SID since 8.1.7 anymore).

Connect from VB APP to Oracle 9i

We had VB app that was connected to Oracle 8i.
We had Our Forms C/S app running on the users machine.
I downloded ODBC drivers for Oracle and was able to connect the VB APP to Oracle 8i.
Now we have forms 10g and so there is no SQL NET installed on the users machine.
How do I make the VB APP talk to the databse.
I tried installing only SQL NET from Forms 10g CD and it had no custom install. Either its all or none.
Any input will be greatly appreciated.

Forms 6i is the last release that has client/server runtime suopport. Oatch 16 is certified against an Oracle 10g database.

Connection from MS Access to Oracle DB

Hi,
One of my test application, running in windows XP is using MS ACCESS. They need to connect to oracle DB (10GR2). What all should i install at the client side to connect to my DB Listeners ?
I thought of installaing 10G client at the application PC. Is it needed or just installing ODBC and NET8 is enough ?... If so where will i get ODBC and Net8 for download ?
Regards,
Jibu

Hi Jibu
You need at least to create an ODBC connection to your Oracle database using the {Microsoft ODBC for Oracle} driver.
Why the MS driver? Oracle supplies their own, and either way you still need to install the oracle client. ODBC is NOT a replacement for native database connection layers -- at least not if the database is other than MS. There's not tell what MS does with its own stuff.

Connect from Windows Client to Oracle 10g for Windows 64-bit

Have an environment currently running Oracle 10g 32-bit on Windows 2000 Standard, and need to migrate to Oracle 10g 64-bit for Windows. Users connect to the 10g 32-bit database using the Oracle Client for Windows 10g loaded on remote PC's. If we migrate to the Oracle 10g 64-bit on Windows 2003 Server Enteprise Edition 64-bit, what type of client do I have to install on the PC's to access the Oracle 10g 64-bit database?
Any ehlp/insight will be greatly appreciated.

In addition to install 32-bit Oracle client to 32-bit Windows OS, you need to know whether your application is compiled to run in 32-bit or 64-bit.

For example, MS SQL Server 2005 uses 32-bit DTS, and SSIS, which needs 32-bit Oracle client
If you don't know, get a copy of both 32-bit and 64-bit Oracle client, and try one-by-one to know for sure. Please be aware that if regsvr32.exe in the Windows has been overwritten by older software installation, it won't register some DLL properly, and Oracle ODBC, or OLE DB won't show up as well

Connect from Windows 98 to Oracle 8.1 fails

Hi...
we are using Power Builder to connect
to the Oracle 8.1 DB. It's running under Windows98 and the connect fails every time.
Under Win NT 4 it still works fine.
Are there some diffrent parameters between
win98 & NT? Wich they are, and how do i use them.
hopefull best regards...

Connect from OS/390 to Oracle on NT

We need to connect to Oracle on an NT platform from an OS/390 system. I have seen a reference to something called Oracle Access Manager that purports to do this but I can't find any info on this product. Can anyone tell me if this product is still offered and if it is the right way to go? Any other suggestions would be appreciated.
Thanks in Advance

Just modify your TNSNAMES file and add the entry for your database on NT. [email protected]

JMS connection from SAP PI to Oracle AQ via JNDI...

Hi,
I am currently working on a project that requires connections between PI and Oracle AQ. It was advised that we shoule use PI JMS adpater with JNDI driver. However, it seems that not many people have tried this approach.
Has anyone had similar solutions in production ? How repliable it is ?
Your help is very much appreciated
Tim

Hi Tim,
We implemented a similar scenario and now itu2019s still working.
You have to configure a JNDI connection, but not directly with the Oracle AQ. The Oracle AQ are just queues, and you need a JMS provider in order to establish the connection with these queues. The solution we implemented was:
1. Configure one OC4J server as JMS provider for the Oracle AQ queues.
2. Configure JMS communication channels in SAP PI to establish the connection with the OC4J server.
Maybe you can use a different and newer JMS provider, as BEA Weblogic or SAP WAS (I donu2019t know if itu2019s possible).
We implement the scenario in SAP PI 7.0, and with this version we had a problem: When the communication between JMS adapter and the queues was broken (the DDBB fell down for example), the channel failed, itu2019s normal. But when the DDBB was already running the channel stayed in an error state, and we had to restart the channel manually. The response of SAP to this issue was that the channel behavior was correct because the connection failed.
But this problem occurred rarely, maybe once a month. The solution is very reliable, we exchange a lot of message with this solution, and support messages of any size with an excellent performance.
Best Regards,
Roberto

Error when setting up connection from Universe Designer to Oracle database

Hello,
I am attempting to create a connection to an Oracle 10 database in Universe Designer. I am currently running Business Objects XI 3.1 SP3 on a 32 bit machine. I have the Oracle client installed. In Universe Designer when I attempt to create a new connection using the Oracle 10 client I receive the following error.
CS:DBDriver failed to load : C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86\dataAccess\connectionServer\dbd_oci.dll (The specified module could not be found.)
The dbd_oci.dll file does exist in the directory listed above. Has anyone encountered this issue?
Thanks in advance.
Brock

Hello Brock,
Do you have multiple SQL clients installed on your system? If so, uninstall the previous versions. Check if the PATH variable is set to correct bin path and then try testing it again.
