Ms-access XP front-end and oracle ODBC driver

Hi all,
I need to set up 5 workstations with ms-access front end accessing an oracle database through Oracle ODBC 9.2.0.5.0 driver and linked tables.
My main concern is to learn about any issues that may limit what can and can�t be done through access as opposed to an oracle client. I found out that the maximum size of an access XP database is 2GB, but I have not found accurate information as to the maximum number of records ms-access can handle per table. This would be of critical importance to me because the tables I'm working with may eventually hold up to hundreds of thousands of records.
Concurrency control is also an important topic since 2 or more of the clients may at some point read or write information on the same tables.
Answers to these questions and any other issues of special importance would be greatly appreciated.
Thanks a lot,
JP.

Just seen this message you had posted to OTN. I am currently looking for some sample codes developing applications using MS Access as front end connected to Oracle database. I appreciate if you can provide me some sample codes that has a master-detail-relationship type of access form that performs an inserts into the master and detail table. Thanks a lot.

Lotus notes as a front end and oracle as backend

Dear All,
Can i use lotus notes as a front end and oracle as backend atleast for few forms in my application.
If Yes how to go about it.
I have not tried it even once
Kindly also advice if this is appropriate forum to ask this question
Best Regards,
Devendra Shelke

Dear All,
Context for asking above question :
We use Form 6i and Report 6i, Application Server 9i and 9i DB.
But for some forms we want the user to enter the data through Lotus Notes but get updated in 9i DB used by Form 6i.

ASP pages and Oracle ODBC Driver

I have a number of ASP pages that need to be updated to connect to Oracle using the ORACLE ODBC driver. Currently, these pages connect using the Microsoft ODBC driver for Oracle. I do not know of all the details yet as I havent seen the pages or network for which they reside on and I havent been supplied with details on version information. I would assume I am working with recent versions of all software.
What Im curious about is if anyone has done this sort of driver change before and if you have any suggestions on how I would go about doing this, or if there are things that I need to be aware of that arent evident at first glance.
Again, I am switching from the odbc driver provided by Microsoft to a version of the odbc driver provided by Oracle.
Thanks for any and all information.

I'll assume that there is some reason that necessitates switching drivers. If there's not going to be a benefit, I'd suggest not changing.
That said, changing drivers should be relatively painless. If your ASP makes database connections using DSN's, simply go to the ODBC Data Source Administrator, rename the old Microsoft DSN, and create a new DSN using the Oracle driver with the name your ASP is looking for. If your ASP specifies the ODBC driver in its connect string, you'll have to modify all the ASP connect strings to use the Oracle driver. If all goes well, your ASP will now be up & running using the Oracle driver.
As we all know, however, reality and theory are often at odds with each other. While your ASP should be connecting to the database correctly when you make these changes, please do some thorough testing to verify that everything works like you expect. The ODBC specification permits drivers to have a variety of behaviors in certain conditions. Applications written with one ODBC driver often end up relying on one of these behaviors, and may break when the ODBC driver changes.

Removing admin password form Access 2003 database front end and back end

We have a legacy database that has been passed down from the original creator, who is no longer with the organization. It was created in Access 2003. It has a front end and a back end. The original admin password can not be located and we are in the process
of upgrading this application to 2010. Is there a way to remove that password so we can make changes to the original files?

Hi,
What password are you talking about, the one created with the workgroup manager? That will be difficult since 2010 doesn't have the workgroup manager anymore. You can still use the database in the 2010 environment but you can't make any changes to the original
database without the password.

Oracle ODBC driver with Access Application

I get a problem when using MS-Access 2007 DAO recordset built on table hosted by an Oracle database 10g and connected thru ODBC
The table scheme is :
idPartenaire : number(11)
libelle : varchar2(250)
code : varchar2(5)
actif : number(1)
idCollege :numner(11)
idPartenaire is generated by a sequence read in a trigger fired before insert on th table.
The code I use in Access is :
The query associated with the form is :
"select * from table1"
and the event procedure connected to a button on the form is :
Private Sub Commande0_Click()
Dim rs As DAO.Recordset
Me.Recordset.AddNew
Me.Recordset!libelle = CStr(Rnd) ' some value
Me.Recordset!code = “”
Me.Recordset!actif = -1
Me.Recordset!idCollege = 1
Me.Recordset.Update
Me.Recordset.Bookmark = Me.Recordset.LastModified
Dim idtemp As Long
idtemp = Me.Recordset.idPartenaire
Me.Requery
Me.Recordset.FindFirst "idPartenaire = " & idtemp
Set rs = Nothing
End Sub
When I run this code, I get an error 3167 (current record is deleted) on the line :
idtemp = Me.Recordset.idPartenaire
If I change the ligne :
Me.Recordset!code = “”
By :
Me.Recordset!code = “xxxx”
or if I comment this line, the error does not appear and I get the right value in idtemp variable.
I tried also with the same table in a SQL Server database table. In this case it works fine in all cases.
So, I seems that the problem is due to the Oracle ODBC driver. I tried with different versions of Oracle ODBC drivers (v10.0.2.4, v11.1.6)
I search on Internet but I have not found any explanation or solution.
Does anybody experiment the same problem (and find a solution)?
Gilles Roussel.

The two lines you quote aren't errors, they're warnings and they're pretty standard fare. If there isn't anything else in the ODBC log, then the driver isn't returning any errors. I'm not sure why Access is failing, so let's look at the client configuration first.
- I assume you've successfully installed the 8.1.6 client on the machine with Access. Were there any errors during the install?
- You say you're using the 8.1.6 version of the Oracle ODBC driver-- can you look to see what the last digit of the version is? If possible, I'd start by downloading the most recent 8.1.6.x ODBC driver from OTN.
- Check which version of the MDAC you have installed (new versions & a version checker are available from Microsoft at <http://www.microsoft.com/data>.
- The ODBC driver you download above will list which versions of the MDAC it is expected to work with. Make sure your version is one of the listed versions.

Authentication with UME separation of front end and back end

My webdynpro project has 2 application. One for Admin one for Rating.
Is it possible to create a java class at Webdynpro level and share it between the 2 applications?
Why the need?
Created a custom class (lets called it CommonEJB), to point to the right pages and set of UI controls after the initial login with UME. This class utilizes the IWDClientUser.getSAPUset() method to get IUser object.
If it is not possible to create a java class at Webdynpro, then this ejb will need to be deployed to the backend.
Putting it at the backend is not good as security wise, its always better to separate the authentication between front and back end.
Any ideas/solutions?
thanks

Well, i wish to create a java class that can separate the view areas depending on their login.
lets say you're a manager, u can see certain views. and if you're a supervisor u see another. This is achieved using the java class with information from getSAPUser() position. After retrieving the position, using the java class will programmatically assigned the appropriate views, buttons, tabs etc.
so this class need to in front end, and not back end. problem is we have 2 application.
if the class is created front end in one application can it be shared with another.

Oracle ODBC Driver adds bind variable when browsing whole table in Access

Hi, we are looking for some reasons why we may see this behavior in the Oracle ODBC driver (10gR2 and 11g) when using Microsoft Access (2003 or 2007)...
1) Link a table from the Oracle database.
2) Double-click the newly linked table to "browse" it.
Oracle sends the following statement to the server:
{color:#0000ff}select * from linked_table where primary_key = :b1{color}
It then proceeds to read the entire table.
If I tell Microsoft Access that there is no primary key, the query gets sent as:
{color:#0000ff}select * from linked_table{color}
And the query comes back as soon as the first 100 or so rows are fetched which is quite quickly.
ADDITIONAL NOTES:
1) If the table has a primary key or unique constraint, Microsoft Access automatically assigns that as the primary key.
2) We can stop the behavior in #1 if we wrap a view around it which prevents Access from discovering that information and then it prompts for a primary key definition.
3) If we use the Microsoft ODBC driver, the bind variable is not added no matter what the primary key defintiion is.
We're stumped and are looking for solutions and/or workarounds without having to wrap all of our tables in views to hide the fact that there is a primary key.
Thanks,
Steve

Thanks for the response, Greg.
The specific question I am seeking an answer for (sorry it was not clear on my first message) is this:
Why does the Oracle driver add the bind variable to the query only when the primary key is defined?
The Microsoft ODBC driver does not add the bind variable with or without a primary key defined.
You asked how I traced this statement and what I am doing is launching the query in Access and then using TOAD to view the V$SESSION and V$SQL_TEXT_WITH_NEWLINES views. All I do is change the driver. This is just for a simple browse table (double-click on the table) which should send
select * from table
However, whenever I use the Oracle ODBC driver (with a primary key defined) it sends
select * from table where primary_key = :1
If I remove the primary key on the table definition, the Oracle driver sends
select * from table
What is it about the primary key that could cause that behavior?
I don't think it is the MDAC/Jet level because this is the conversion to the native SQL statement not the Jet version. I know the Oracle driver has to do that part because you have those workaround options like don't add the RULE hint, etc. That's not part of the Jet engine.
Hope that helps. I'm just baffled over this one and wish I knew where to go next.

Setting up an Oracle ODBC Driver and Essbase

Hi all,
I am trying to retrieve data directly from Essbase into SAS (Statistical Analysis Software) by setting up an Oracle ODBC Driver and Essbase.
I read this document in the below link and I was convinced that I could use ODBC to connect to Essbase, but our data administrator says that Essbase is an OLAP database and can NOT use ODBC.
http://docs.oracle.com/cd/E10530_01/doc/epm.931/esb_sqlint.pdf
I am a SAS programmer, but I have no background in technical configuration, so I was wondering if someone can help me if it is really possible or not to connect to Essbase using ODBC.
If it is possible, I have a follow up question...
I followed this link below to do a set up and did so successfully before the actual step to add a new data source to ODBC driver.
I should be able to select the TNS Service Name from the drop down list. This name will be that which I named in the TNSNAMES.ora file’s Alias = section, but I don’t see this option…
It would be great if someone knows why I do not see this option populated under drop-down in the screenshot.
Setting up an Oracle ODBC Driver and Data Source | Ten Six Consulting

1) As I recall, the problem of returning 0 is caused either by an outdated version of the ODBC driver or of the MDAC (Microsoft Data Access Components). Updated versions of the ODBC driver are available here on OTN and updated versions of the MDAC are available at <http://www.microsoft.com/data>.
2) Versioning-
To determine the version of the Oracle8 ODBC driver you should be using, simply match up the first three digits of the ODBC driver version and the Oracle client version (see chart Mr. Oehl posted). The 8.1.5.6 ODBC driver should go on an 8.1.5.x.x system, the 8.1.6.1 ODBC driver should go on an 8.1.6.x.x system. If you have an Oracle7 client, you'll need one of the version 2.5x Oracle7 ODBC drivers.
Any ODBC driver should connect with any Oracle database. No need to match anything up there. You can determine the version of the database you're connected to by calling the ODBC function SQLGetInfo with the InfoType SQL_DBMS_VER.
A little elaboration on version numbers
- Oracle versions are generally 5 digits (i.e. 8.0.5.2.4, 8.1.5.1.1). The versions that you get on CD's are generally (always?) x.x.x.0.0 versions (i.e. 8.1.5.0.0, 8.1.6.0.0). The last two digits are incremented by periodic patchkit releases <ftp://oracle-ftp.oracle.com/server/patchsets/wgt_tech/server/windowsNT/>
- ODBC drivers must report versions in 4 parts, each part having 2 digits (i.e. 8.01.05.05). Since we're lazy about typing extra 0's, we simplify this and just refer to the 8.1.5.5 ODBC driver.
- The 8.1.5.x ODBC driver is built with the client libraries that ship with Oracle 8.1.5.x.x, the 8.1.6.x ODBC driver is built with the client libraries that ship with Oracle 8.1.6.x.x, etc. This is why I said above that you need to match the first 3 version numbers between Oracle client and ODBC driver to determine which to use.
I hope this is more enlightening than confusing...

What is BW Front-end and Whats BW Back-end? Technica ? Functional?

Hi Gurus,
Can some one throw light on the diff between a BW Front-end and BW BAck-end? How will u diff the responsibilities of a Functional BW Consultant and Technical BW Consultant?
thanks
kishore karnati

Hi,
BW Front end is the one that deals with reporting. Eg: BEx
BW back end is the one that deals with the components that stores data which is used for the reporting purpose.
Eg: R3
Functional consultant comes into picture when there is a need to understand the functional aspects of a requirement, say for example, you have a requirement to use Sales Order in your BW application, as a pure BW person, you wont know what a Sales Order is about. A functional consultant has the ability here to map the sales order requirement in the BW application. This means that, he knows what field and what table this sales order relates to. This way, a functional consultant maps the user requirements to the technical detail in the system.
A pure BW consultant is one who knows how to setup data extraction from source system , how to build various components in a BW system, how to schedule a load, how to troubleshoot in case of any issues in the BW application.
Hope this helps..
Assign points if this helps...
Thanks,

Lync 2013 Enterprise load balancing on the front end and edge pool

Hi,
I am setting up a Lync 2013 Enterprise deployment consisting of a Front End pool (x2 FE servers) and an Edge pool (x2 Edge servers). I'm seeing some conflicting advice regarding load balancing using hardware or DNS for the front end and the edge.
On the front end I have 2 internal DNS records 'lyncfepool1.contoso.local' each of which map to one of the IPs of the FE servers. I've used my details to populate the Detailed Design Planner excel spreadsheet and am told that I require a HLB to load
balance my front end pool. I'm aware of the need to load balance HTTPS traffic internally (which will be done by TMG) however other traffic to the front end (SIP, etc) can be balanced by DNS only, and not require a HLB?
Can someone clarify the front end requirement?
Also - looking now at the edge pool - this site again have two edge servers in a pool. We are using a total of six private IP addresses, two per edge service (2 x av.contoso.com, 2 x sip.contoso.com and 2 x webcon.contoso.com). These will be
NAT'ed by the external firewall and directed to the respective external (DMZ) IP addresses on the Edge servers on port 443. I know this isn't true roundrobin due to the intelligence of the Lync client when connecting (in that the Lync client will connect
to one of the public IPs and if it can't connect, it will know to connect to the other service IP), however I want to clarify this set up, particularly the need to direct the external public IP traffic at the DMZ Edge IP specified in the topology builder.
I've attached a basic diagram of the external/DMZ/Edge side which hopefully helps with this question
Persevere, Persevere, Per..

That is because you will always need HLB for a front-end server since it hosts the Lync webservices which use HTTP/HTTPS traffic.
The description on the calculation tool also describes this correctly:
Supports Standard and Enterprise pools (up to 12 nodes), with pure device-based load balancing or a combination of DNS load balancing and device-based load balancing (for
Lync web services)
You can use either Hardware or DNS loadbalancing for SIP traffic only, but you will always need a HLB for the webservices. Both are applicable for the Front-End so you have either
full HLB for both SIP and HTTP(S) traffic
DNS LB for SIP traffic and HLB for HTTP(S) traffic
Hope this is more clear :-)

Https front end and http backend

Thanks for the quick reply....there is another port 80 rule setup for that vip....I was using that to test with the app until I got the front end https rules working....
my port 80 rules just says listen to 10.19.55.10 on port 80 and load balance btwn the webervers on port 8x in the back end...
I am trying to do https front end and http backend....
no where in my SSL config have I configured port 80....but when I suspend that rule it all fails....
I am wondering if the backend server sessions are happening properly?
I don't fully get what you mean by "You need to have the rule in port 443 to match traffic coming from the client and the clear text rule (port 81) to match traffic already decrypted coming from the SSL module"
Haven'tI done that?
Thanks again!

Front End to Oracle Database - Advice Needed

Hi
My company has recently purchased an Oracle Database. Are there any advantages in creating the front end in Oracle as opposed to writing the front end in Java.
I am interested to know if one method is preferred over the other. I was planning on writing it entirely in Java.
Any help or advice would be appreciated.
Thanks
