JDBC driver, multiple oracle homes, tns issue

Environment: Win 2003 Server 32 bit; Coldfusion 8; oracle db; IIS; Sequelink 5.4
I'm having a JDBC driver problem on 32bit. I've installed two oracle clients on the box, one 10g and recently an 11g. With the new 11g install, I've still wanted my datasources to all point to 10g for now and I've changed the environment path to have the 10g path first. Everything is good except for my coldfusion data sources, they will only now connect to 11g. When verifying 10g data sources I get
[Macromedia][SequeLink JDBC Driver][ODBC Socket][Oracle][ODBC][Ora]ORA-12154: TNS:could not resolve the connect identifier specified
So I add a 10g service to the 11g tns names and the datasource connects just fine. It's a work around but not a good one. The main issue is that the JDBC driver seems to be pointing to my 11g tns for everything and that is the problem.

You mention Sequelink and your message refers to ODBC Socket.
When you create this datasource in CF, are you using ODBCSocket as the DSN type? IS that because perhaps you're on CF Standard and don't have Oracle listed as a driver type option?
In that case, you may want to consider getting an Oracle JDBC driver, then using the "Other" DSN type when creating a DSN in the CF Admin.
There are various resources walking through how to do this:
http://blog.razuna.com/2008/01/25/configure-the-jdbc-driver-for-oracle-on-coldfusion-8-sta ndard-edition/
http://kb2.adobe.com/cps/183/tn_18344.html (though see comment in above entry about a concern using the "thin" driver referred to in this technote)
http://www.technicallychris.com/2006/09/04/configuring-oracle-for-coldfusion-mx-standard/ (this offers a useful follow up tip to the technote)
Hope that helps.

Multiple Oracle Homes

Hi everybody,
I have Oracle 9i installed on my Windows machine.
I installed Oracle Developer Suite, but could not login due to TNS errors.
I have a little idea of what the problem is. We need to edit TNSNAMES.ORA file so that it could resolve the service name.
Can u please help me out in configuring Developer Suite to work properly?
Thanks.

Not quite sure why your title is Multiple Oracle Homes. Can you connect to SQLPLUS or any other product in the suite? Is it just Designer you are having hassles with? Do you have the database on the same machine and can you connect to that? If you are successful at connecting to SQLPLUS, then take a look at the tnsnames file in the Database network /admin directories.
There was a bug at one point where the tnsnames would fail if the network connect string was between 184 and 192 characters in length. You may be running into this. In which case if your tnsnames.ora contains
(CONNECT_DATA =(SID = <SID>), you can change this to use (CONNECT_DATA =(SERVICE_NAME= <SID>)

Multiple Oracle home

Hi ,
I have some doubt which needs to be cleared.
If I will install multiple oracle home like ORACLE_HOME=/u01/app/oracle/product/10.1.0/asm
ORACLE_HOME=/u01/app/oracle/product/9.2.0
ORACLE_HOME=/u01/app/oracle/product/10.2.0
ORACLE_HOME=/u01/app/oracle/product/crs
Now in this when I will set export ORACLE_HOME then which version will be picked up.
Is ORAENV isgoing to come into picture.
Please throw some light on it.

Asif KabirAsif,
Your advice to hard code the Oracle environment directly into the profile is poorly thought out. And a direct carry over of 'worst practices' unfortunately taught in some Oracle related classes.
The OP did correctly identify oraenv (as described in the "Administrator's Reference for UNIX-Based Operating Systems" at http://www.oracle.com/pls/db102/portal.portal_db?selected=4) as the preferred solution. Putting THAT into the profile (using ORAENV_ASK as described in the manual) is OK.
I'll leave you to figure out why the difference - I've posted many times about that in these forums.

Please help. ive been working on it for days =(.

If you're running a Web app, put all JARs that your app needs in the WEB-INF/lib directory. That's always in the CLASSPATH.
I don't know WebSphere. Do you really have to edit something to add all those CLASSPATH entries?
In Tomcat, all I'd have to do is put a WAR file in the webapps directory.
Your code needs some work. You're not following Sun's Java coding standards. Capitalize your class name, for starters.
Is the username and password for your database still "scott" and "tiger"? Nice security there.
Your connect method makes a database connection. Do you leave it to users to close it? (You do close your connections when you're done with them, don't you?)
I'd make Connection a data member and create it in a constructor. I'd write a close method to close it up.
Doesn't WebSphere do connection pooling? Do you really want to write your own class to handle this?

Problem with JDBC driver for Oracle 10g

Hi.
I've successfully accessed a MySQL database via a DataSource from a servlet (that uses a DAO). However, when I try to do the same with an Oracle 10g Database, I get the error message:
Cannot load JDBC driver class 'oracle.jdbc.driver.OracleDriver'
I'm using J2SE1.5.0/5.0 and ojdbc14.jar, the latter of which I downloaded this afternoon as the latest driver JAR available on the Oracle site. As with the MySQL driver, I've placed it in the commons\lib folder within Tomcat. (I've also, of course, made the necessary modifications to server.xml and web.xml.)
Upon examining the ReadMe file at the top of the Oracle download page, I found that the oracle.jdbc.driver package is now deprecated and all references to oracle.jdbc.driver should be replaced with oracle.jdbc. However, I got a similar error message when I tried this modification. Upon examining the contents of ojdbc.jar, I found that the driver was there and that it was, in fact, still oracle\jdbc\driver\OracleDriver!
It appears as though the Oracle site has not been updated with a driver that matches its latest documentation. However, this does not explain why the driver is not even being loacted when it is in the correct place. Can anybody shed any light on this? Any help would be much appreciated.
Thanks in anticipation.
Cheers.

I've successfully accessed a MySQL database via a
DataSource from a servlet (that uses a DAO). However,
when I try to do the same with an Oracle 10g
Database, I get the error message:
Cannot load JDBC driver class 'oracle.jdbc.driver.OracleDriver'
That's different from a ClassNotFoundException.
>
I'm using J2SE1.5.0/5.0 and ojdbc14.jar, the latter
of which I downloaded this afternoon as the latest
driver JAR available on the Oracle site. So you got ojdbc14.jar or ojdbc14_g.jar under the 10g drivers?
As with the
MySQL driver, I've placed it in the commons\lib
folder within Tomcat. I think it's a better idea to put in the WEB-INF/lib directory of your Web app rather than commons/lib. WAR files are a very good idea, too.
(I've also, of course, made the
necessary modifications to server.xml and web.xml.)So you're using a JNDI data source? It sounds to me like that's where the problem is.
You should not have to edit the server.xml at all. If you put the <ResourceParams> in a context XML file with the same name as your WAR file into the TOMCAT_HOME/webapps directory it'll be picked up automatically. (It might also be accessible in the META-INF directory for your app, but I haven't done it that way.)
Upon examining the ReadMe file at the top of the
Oracle download page, I found that the
oracle.jdbc.driver package is now deprecated and all
references to oracle.jdbc.driver should be replaced
with oracle.jdbc.
However, I got a similar error
message when I tried this modification. Upon
examining the contents of ojdbc.jar, I found that the
driver was there and that it was, in fact, still
oracle\jdbc\driver\OracleDriver! The fully-resolved class name you should be using MUST match the class that's in the ojdbc14.jar that you're using. Look in the JAR for the definitive answer: the one that I downloaded is still using the oracle.jdbc.driver package for OracleDriver.class. Ignore the docs - use the name that's in the JAR.
It appears as though the Oracle site has not been
updated with a driver that matches its latest
documentation. That often happens with docs.
However, this does not explain why the
driver is not even being loacted when it is in the
correct place. Can anybody shed any light on this?
Any help would be much appreciated.I think the problem lies in your web.xml and server.xml
I'd recommend that you decouple the JDBC from the Web app for now. See if you can connect to Oracle using a simple desktop app and leave the Web piece out of the equation for now. Once you can do that, you'll be certain that the parameters you're using are correct and you can turn your attention to getting the Tomcat configuration right.
PS - I'm using Oracle 9.2.0.1 and Tomcat successfully right now, so it can be done.

Guidelines regarding directory structure for multiple Oracle homes on Unix!

Hi All,
Are there any guidelines published regarding directory structures that should be defined while using multiple Oracle homes on Unix/Linux box?
I am looking for guidelines regarding admin and oradata folders so that we dont accidentally mess up with the DB contents with a wrong Oracle home.
Its a development server with 8i and 10g. 11g might also get loaded on the same server in future.
Thanks in advance...
Regards

Thanks Maran.
I have already checked many installation guides before posting here. All of them mention about creating folders like /admin or /oradata on various mount points but none of the naming conventions really indicate whether it is a 8i database or a 10g database.
This is required when you are having multiple Oracle installations under /opt and databases are running from different mount points.

Error when SDM JDBC driver for Oracle

When deploying the JDBC driver for Oracle on PI 7.0, I failed to achive. I got the following trace information from SDM.
After checking the system directory structure, I found that very interesting thing. First I downloaded aii_af_jmsproviderlib.sda from the directory of ../SAP AG/0/3.0...and zip oracle jdbc driver into it, and I deployed the sda file with SDM back to the system with the option update deployed SDAs that hava any version. Curious the sda file was put into another directory of ../SAP AG/1/3.0... a new directory which was just created during the deployment.
This never happen before and is this the reason why deploy failed.

Shared cluster with multiple oracle homes

Hi All,
I got to build a shared oracle RAC cluster with multiple oracle home installation ( 10g R1 , 10g R2 , and 11g R1 & 2).
Of course the cluster ware will be version 11.2, but I wondered if there is any dependency on how I install oracle software? Do I have to start with 10g installation first? can I do 11g and then 10g?
Is there anything I should be aware of ?

I installed Oracle Application Server Enterprise which includes AS, Database, OID, Web Cache, SSO etc. and OSES on the same machine. Everything works except I think the windows version of OSES and AS need some patches so the crawler isn't working right. Everything does, however, install and run. I think Oracle develops everything in Linux (rumors of them now using Solaris) so on Linux everything should go smoother.

Regarding Multiple Oracle Homes

Hello,
Does all of the Oracle products support multiple homes ?
Can oracle 8i and oracle 8 products be kept in same oracle home ?
thanks
null

Hi Raj,
To answer your first question, No, not all of Oracle products
support multiple homes. All Oracle7 products and all release
8.0.3 are non-multiple Oracle home products. Oracle 8i lite
cannot support multiple oracle homes either.
In regards to your second question, no Oracle8i and and Oracle
8.0 products cannot be kept in the same Oracle home. Releases
prior to 8.1.3 cannot be installed in an Oracle home that was
created by a release of 8.1.3, 8.1.4 or 8.1.5.
Hope that helps,

Oracle XE (Windows) Multiple Oracle Homes

I have a question in regards to Oracle Express Edition and how it maintains Oracle Home.
I currently have multiple Oracle Homes on my machine. In order for apps like SQL Developer or PLSQL Developer to see the correct TNSNAMES entries, I usually have to use the Home Selector from the Installation tools to properly obtain the correct tnsnames entries in the dropdowns.
Now, I'm a Linux DBA, not to keen on Oracle environments for Windows. But, when I installed Oracle Express Edition, none of my Applications SQL Developer or PLSQL Developer recognize the tnsnames entries for my environment. From the 9i Home Selector I see that it is in the correct environment I want it to use. But it seems Express has overriden somehow.
Can anyone lead me into the right direction to switch between my XE Environment to my 9i environments?
Thanks.

I did it too, but the beta over beta software is just too dangerous.. you never know what is crashing your system :)

Multiple oracle homes installation

i have installed oracle 9i database on single sever where 8i is residing using multiple oracle homes.After installation some folders and files related to 9i created in 8i home directory(eg:9i admin related folder create in 8i admin folder).but i dont want to create like that.is there any way to create all files related to 9i should reside on that 9i home directory only?

You didn't specified the OS.
Assume that your OS is Unix-like (Solaris, Linux) and your user is oracle.
The answer is very simple. Use different enviroments.
create in home directory (oracle user) two files:
1. .ora_8i
2. .ora_9i
All enviroment variables related for 8i database (ORACLE_BASE, ORACLE_HOME, ORACLE_SID, LD_LIBRARY_PATH etc.) are defined in .ora _8i and all variables for 9i are defined in .ora_9i.
Now, you want working with 8i so you need apply 8i enviroment. To do that simply execute following from shell ". ~/.ora_8i". Now you decided working with 9i so simply execute the ". ~/.ora_9i" from shell.
For installation use the same way. So before you run ./runInstaller load the apropriate enviroment.

Multiple oracle homes problem

Hi!
I have multiple oracle homes on my machine: Oracle9DB, DevsuiteHome_1 and now as I have just installed Oracle Discoverer 10g....BIToolsHome_1.
The problem is ever since I installed Discoverer, nothing is working......
Can anyone help?
Best regards,
Aparna

Dear Rod,
What I mean by nothing is working is I cannot connect to the dataases. I get 'No listener' error message.
Oracle Hone selector gives the following message:
The is only one Oracle Home defined on this machine and so this tool cannot be used to change your primary Oracle home.
I tried to start the listener service, however, it says:
Listener service started and then stopped.
Is there any solution to this problem?
Thanks and best regards,
Aparna
