TNS listener problem when migrating access app to oracle

I am migrating an access 2000 DB and application to oracle 8i. I have done this successfully on my test machine many times. I am working on the customers machine, and the problem is when I go to migrate the access application, it will not connect to oracle b/c of the TNS listener. The workbench tool ask for a username, pwd, and ODBC driver, but there is no place to put the oracle service name. I ran into this problem at home and I appended the service name onto the password with the '@' symbol, which works for oracle anyway. Like this, 'pwd@sname'. It worked at home, but I keep getting an error here that tns could not resolve service name. When migrating the data, there was a field to put the service name in, but not for migrating the application. I have tried variations in the ODBC driver also, but with no luck. Any other ideas?

Hello,
Is it possible that odbc driver is nor properly installed? If so you may have to re-instlal the odbc driver. If not try out the following steps:
* Go to DataSources [On win2k: start -> settings ->control panel ->Adminsitrative tools -> Data Sources (ODBC)]
* Click Add for the user DSN [say "testDSN"], and select oracle driver here [check if you have oracle 8 driver, if not you may want to install one]
* In the "Oracle ODBC Driver Configuration" window, give you your oracle databse connection details, click the "Test Connection button", it will ask for username and password, give system's username and password
* Use this DSN [testDSN] name in the migration work bench
Thank you and kind regards,

Problem when migrate from WLI2.1 to WLI7

I met this problem when migrating my program from WLI2.1 to WLI7.
It report the following exception in WLI7:
<2002-10-21 下午05时05分15秒> <Error> <HTTP> <101019>

But it's fine in WLI2.1? Who can tell me why and how to solve it?
Thanks

          My JMS experience on WLS 8.1 ain't great, purley from these error messages it looks like the destination of these messages is the problem. Can you double check the destination exists and is configured correctly.

Yes I do spend a lot of time in China but I have had problems in other countires as well. I am in China right now.
I have two Gmail accounts and one Cox account. Cox is my intranet provider back home. I have had problems with all three accounts.
I have tried several outgoing port settings. 993, 995 465, 587 are some that I can remember trying.
Sometimes my accounts will go offline without me doing anything. This is all a mystery to me. I don't have any idea why I have trouble like this. A few minutes ago I changed my Cox account outgoing port and took the account on line and I got my incoming email but when I tried to forward an email that I got it would not go out.
Any ideas you have would be helpful.

Problem when migrate MS Exchange to virtual machine

Hi,
I have a SMTP node defined in my Solution Manager which send mails to external MS Exchange host without problems.
There is a project for migrate Exchange to a virtual machine. When I modify the SCOT configuration for send mails to new virtual host, i get an error connection message.
I check the exchange relay for my SAP machine and it looks right. There is no problems with net connections between sap system host and exchange host.
Is necesary any special configuration or adaptation in SAP when migrate exchange server to a virtual machine???
Thanks for all.

TNS Listener Problem in 8.1.6

Hi,
While trying to connect to Oracle 8.1.6 , installed on local machine (OS Windows NT 4.0), using Oracle's thin JDBC drivers I get the following error :
TNS-12500: TNS:listener failed to start a dedicated server process
TNS-12537: TNS:connection closed
My database is running in dedicated mode on the same PC where I am executing this JAVA program.
Any pointer. Any Help will be highly appreciated.
Thanks.
King.

According to Oracle Error Message, action for TNS-12500 is that Check the Listener.ORA is properly been set with the Oracle Environment if not make it and stop and start the Oracle and Listener too. If we faced and we did the above and it was working perfect.

TNS Listener -ORA-12514 error following database shutdown - Oracle 11g

Hi
I have hit a problem with my oracle development database.
When in sqlplus I executed the shutdown command, but nothing happened for several minutes and it was just hanging. No messages were displayed to the screen. The only thing was to close the command window. When I open sqlplus again and enter in the user name password as sysdba I am getting ORA 12514 TNS Listener could not resolve service in descriptor. This is odd as I could log on before and use the database. So I thought that the services were still shutting down I waited, and using the Windows snap on tool for Oracle 11g, I restarted the services on the database, but this has had no effect.
Even using EM made no difference because I couldn't log on to perform a startup or recovery.
So, please does anyone know how I can fix this?
Thanks

Hi Daniel,
Just to add to what John said. The Workbench should also generate
synonyms for users that have access (if they have SELECT
privilege on the table) to a table.

Migration: Access 2003 to Oracle SQL

Dear All
I would like to perform a migration from Access 2003, to Oracle 10g. I am using SQL Developer for the task, and have reached the point of capturing the XML file that I exported from Access. I need to create a migration repository on the target database, and this is causing problems as I do not have all the necessary privileges.
In the process, I have been advised that migrations from Access to Oracle are not easy to achieve, and in fact require careful planning before execution. My objective is not really to transfer the data stored within the database file. I only really want to convert Access logic into Oracle SQL code. I was wondering if anyone could advise on the typical odds of success in achieving this task.
I migrated the same Access database to MS SQL Server some time ago and the process seemed to go smoothly. Would it be reasonable then to migrate from MS SQL to Oracle SQL if this is easier?
Any feedback would be very much appreciated.
Thank you.
M

Thanks for your response.
I am not familiar with the intricacies of the process, I'm just following the instructions set out in the Oracle Migrating 3rd Party Databases white paper.
In this document, a process is set out consisting of steps that export an Access database, and then capture it to an Oracle user area with appropriate privileges. The process is achieved through Oracle SQL Developer.
I'd be very grateful if you could expand on your answer if there is a better way of translating Access queries into Oracle SQL. I am aware that an Access front-end is capable of connecting with an Oracle database to execute queries, however, there are considerable limitations in the use of Access that I would like to avoid - hence the migration.

WHEN MIGRATING SQLSERVER REPOSITORY TO ORACLE MODEL USING OraMigWrkBnch

I have captured the the SQLServer database to the omwb repository and migrated it to the Oracle Model. Some of the views,

Has somebody done this before and got the same messages?, does someone know how to solve this problem(s)?, is there a
standard way?
Please help, anyone.

Best way to migrate Access data into Oracle 10g?

what's the best and easiest way to migrate MS Access database into Oracle10g?
Thanks

you can check out this thread ms access db to oracle 10g
<p>also as neil mentioned you need an ODBC to established a database connection between ms access and oracle. be sure that the tables are existing in oracle so you move the data from ms access to oracle tables.</p>

OS migration Access(Win) to Oracle(Linux)

I have migrated a Access DB to Oracle 9.2, both running
on Windows on the same computer. Now I want to do the same thing but to a Oracle DB running on Linux.
Is this possible???
What would the difference be?
IÂ´d appreciate tips in this matter.
/Dag

There is absolutely no difference. Once you have the odbc connection setup to the oracle db, it doesn't matter where it is, on windows or linux.....

Migrate Access DB to Oracle

Hello,
I downloaded migration tool and did the migration of Access 2000 to Oracle.It worked great..
But, I am not seeing the converted database in Oracle.Not sure, if I am missing anything.
I have the converted XML file.
If anybody throw some light on this, I would really appreciate it.
Thanks

you need to use that XML file in the Oracle Migration Workbench and go thru te process of loading the XML, transforming it to the Oracle Model and creating your Oracle Schema in the database. This is all documented in a step by step method in the user's guide

Problem while migrating from Sybase to Oracle using Quick Migrate

Hi,
For SQL Developer version 2.1, while migrating from sybase to oracle, Using Quick migrate, during data move step, for the rows having ''(Blank) values in TEXT data type in SYBASE, which is convertd to CLOB in Oracle, the migration for that table terminates at that row.
However, NULL values in Sybase TEXT data type are successfully inserted in Oracle CLOB.
How can we overcome this?

reproduced and see exception in console, bug logged.

App store and apps problem when migrated

I am going to ask this here because Apple support has not been able to fix this.
Old computer = iMac core 2 duo 2.4GHz 10.6.7
OK so I just bought a new iMac quad core i7 2.93GHz (2010 model on closeout) and from the start I selected to migrate from a time machine backup. Took a long time but worked (well execpt for this problem).
So one thing I noticed after the backup was that there was no app store program installed. I then noticed the OS that was on the machine was 10.6.4 (pre app store). So I did the upgrade and and it's now at 10.6.8.
Problem is the apps won't load (click and nothing happens, click on ones in dock and it bounces once then nothing). So I load up the app store and log in, seems to take my login OK but won't let me do anything like make a purchase or do an update to an older app. It tells me they were purchased with a different account when I try to update and tells me I don't have a valid account when I try to purchase.
Well it's a good account and I went back to the old computer signed out and back in with the 'exact' same info and it works fine on that computer, even did the update to the program that was older"
Called Apple support, ran me through a dozen things (I could tell he was running out of ideas) and he finally said it must be a problem with your account (I seriously doubt it as I use the same account on the old computer, a laptop and 2 'i' devices with no issue).
I think it has something to do with the fact that the migration happened when the OS was older than the app store.
Not sure what to do but I would like to be able to use the apps I purchased and be able to purchase more in the future.
Any ideas?

Well looks like the fix was to download the stand alone 10.6.8 updater and re update the OS.

Application has problems when migrated from 10g to 11g

Hi there,
I am hoping someone can shed some light on a problem I have in moving an application from Oracle 10g to Oracle 11g. The app works fine on 10g (uses Apache webserver with PL/SQL module, and APEX 3.1.2.00.2), but on 11g using the embedded web server and APEX 3.2.0.00.27, it doesnt. Most of the app works fine, but there are a couple of pages that provide the ability to add child rows to a parent/child relationship, where the parameter passing mechanism from one page to the next appears to suffer from some sort of corruption. I have traced this using the "session" and "debug" buttons on the developer interface, which show that the values of the parameters get changed inexplicably, when branching from one page to the next - even when the page is actually branching to itself.
I am using the "Set these items, "With these values" fields in the branch, and have verified that the correct values are being associated with the correct items in the application builder. But while this does work correctly under 10g, with 11g, the wrong values end up being passed. Just prior to the branch the set of parameters have the correct values, but immediately after the branch, one of the values is NULL, another has the value of a different item, and a third has a totally random value - I have no idea were it comes from!
I migrated the application from 10g to 11g using the APEX application developer's Export/Import options. There have been no other changes. Should this have worked? If so, any ideas what might have gone wrong?
Thanks,
Sid.

Well, I managed to solve this, but not in a way that makes much sense.
In desperation (I had tried almost everything else!) I changed the value of "Cached" in the page settings from "No" to "Yes", and ran the app, but the page didnt render correctly (in either Firefox or IE7) - in fact all that displayed was the developers toolbar at the bottom of the page. I changed the value of "Cached" back to "Y", ran the app again, and hey presto - everything worked fine! I actually did this a second time with a fresh import of the app from 10g, just to be sure I wasnt seeing things. I wasnt!
There was just one further issue - everything worked fine apart from this section of code in a page process:-
ELSIF (:p9_filter_type = 5) THEN
IF (:p9_x_gene_list IS NOT NULL) THEN
:p9_filter := :p9_x_gene_list;
END IF;
:p9_entity_types := 'GENE';
END IF;
In 11g the value of :p9_entity_types was not being set to 'GENE' when :p9_filter_type was 5. This was (and still is) working in 10g. I changed the code as follows:-
ELSIF (:p9_filter_type = 5) THEN
:p9_entity_types := 'GENE';
IF (:p9_x_gene_list IS NOT NULL) THEN
:p9_filter := :p9_x_gene_list;
END IF;
END IF;
... and now it works fine in 11g as well.
Only wish I knew why!
