Can Forms Builder access non-Oracle Database?

Does any one know whether Pracle Forms can access othe non-Oracle database via ODBC or JDBC to MS Access or MySQL?

In general, HTML DB gives you access to Oracle database facilities. These include heterogeneous services. Please search this forum for keyword "heterogeneous" and you can follow the threads that interest you.
As for the comparison with brain surgery, I'd rank them about the same in terms of raw thrill.

Can you access non-Oracle database with HTML DB?

Can you access non-Oracle database with HTML DB? If not, will this be possible in the future?
I realize HTML DB is not an open-source product. However, it is necessary sometimes to get non-Oracle database info. JDeveloper supports this. It does not appear to me that HTML DB does. This is a major drawback to it being a product for more potential applications that rely on other database technology such as MySQL, etc.
If it is possible, is this brain surgery to do it. HTML DB offers fast simplified development and it would be good if it was built in. Does anyone know of an example of accessing non-Oracle database that is available?

Connect Oracle Form Builder 10g to Oracle Database 10g Express

Hi,
I'm new to Oracle.
I've installed both form builder and database 10g express.
I tried to connect form builder to HR sample database in 10g express with the following:
user name: hr
password: hr
database: hr
but I received message: ora-12154: tns could not resolve the connect identifier specified.
Can anyone help me on that? Do I need to change the tnsnames.ora?
If yes, what should I need to change in order to connect to the HR sample?
Thank you.

Yes you need to have an entry in the tnsnames.ora file for you database service name or sid. The service name or sid is usually XE unless you changed it when you installed 10g express.

Accessing non-oracle databases from oracle

Is there any way to access from oracle to non-oracle databases and copy the data using COPY command?

Hi Nitin!
You can access these legacy applications as so-called external applications. Check out the Application Server Single Sign On guide.

Form Builder connecting to Oracle database

I recently dowloaded the Personal Edition of the Oracle 10g database.
Having done that, I installed a copy of Oracle Forms 6i which I had.
When I used to connect to the database from the Forms Builder, I only entered username "scott" and password "tiger".
Now, it seems I also need to enter the database name to connect.
I tried "Oracle10g", which I think is the instance name, but I get an error about not being able to "resolve service name."
Can someone help me with this?
Thank you.

Although not related to your problem, connecting Forms 6i to a 10g database isn't really a good idea. Although it is supported by Oracle, you are likely to have problems. Remember that Forms/Reports 6i is very old (and no longer supported) and was based on the Oracle 8.0.6 architecture. Additionally, be sure you are using Forms 6.0.8.22 (Patch 13) or newer if you plan to connect to 10.x.
That said, your problem is not related to the versions you are using. It is caused by the fact that the database is considered "remote" relative to Forms. This is true even though both products are likely installed on the same machine. By having them installed in different Oracle Homes (which you must), the database might as well be on another machine.
Short answer, you need to add the database information to the tnsnames.ora file found in the Forms Oracle Home. More specifically, it can be found in:
%ORACLE_HOME%\NET80\ADMIN
The other alternative is to set TNS_ADMIN in the system environment (not the Windows Registry). This will point to the database's tnsnames.ora and will allow all installed products to access the same file.

Can Jdeveloper Be Used For Non-Oracle Databases

I have been trying to evaluate Jdeveloper 9i and Jbuilder 7 Enterprise for Swing database development. I am particularly interested in the productivity enhancements such as BC4J and Jclient. The underlying database might be Oracle, SapDb (excellent, easy to use, and free), SQLServer, etc.
I evaluated Jbuilder Enterprise tools and it worked flawlessly with SapDb. This emphasized using their DataExpress and DbSwing components which provide many useful capabilities similar to BC4j and Jclient. It also involved using their DBPilot tool which allows browsing similar to that provided via a Jdeveloper connection.
I tried to use Jdeveloper for the same SapDB and it is essentially non-functional. I followed the instructions for using a non-default driver and tried to define a connection. It behaved inconsistently: often saying no suitable driver can be found and yet when you edit the connection and test without making any changes, it works. If you try to establish a BC4J definition, it is very inconsistent and fails to recognize important details as foreign keys. Even if you define a ViewLink manually, it still does not work properly if you attempt to define a Master-Detail Jclient form. As I have stated, all these types of capabilities worked flawlessly in their Jbuilder equivalent. Furthermore, I really like the fact that Jbuilder gives many of BC4Js benefits without needing a BC4J J2EE container.
Has anyone had real success using Jdeveloper's advanced features to develop for non-Oracle databases and if so, how did you get around these types of problems?

Hi,
generally, SCAN can be used for 10g databases and you discovered the first half: for 10g databases you will have to modify the REMOTE_LISTENER entry for each 10g database instance to point to the SCAN listeners (as opposed to pointing to the remote local listeners, which is the default in 10g). You could even have the databases registers themselves with SCAN and the remote listeners, if you wanted to... It's more or less a matter of configuration. But for simplification reasons, I will stick to the case where you have your 10g databases register with the SCAN listeners only.
Now the other half is the client and the client configuration. An 11g Rel. 2 client configured for RAC would have a TNSNAMES entry that has only one address line for the RAC databases. The host entry in this one address line should point to the SCAN (the SCAN name is ideally resolved in DNS). A 10g client configured for RAC would have as many address lines in the TNSNAMES as you have nodes in the cluster.
The 10g client SCAN configuration would then be in the middle so to speak: You would have 3 address lines in your TNSNAMES, in which each host entry would resolve to one SCAN address (I assume you will use the recommended default of 3 SCAN IPs). If you choose, you can have a name resolution for each of your SCAN IPs, but this would not be required. Now, why would you do it this way? Because this configuration will always work and does not make you dependent on certain functionality that your DNS server may or may not offer.
For the remaining questions: SCAN is a DNS entry resolving one name to more than one (typically 3) IP addresses. OID is short for Oracle Internet Directory, which is a complete LDAP server. And you are right that there is no document how to configure 10g clients for SCAN from Oracle yet. However, there is a quite good document on SCAN on otn.oracle.com/rac, but I am sure you are aware of it already.
Hope that helps. Thanks,
Markus

Connection to non-Oracle databases(MS Access) with Discoverer

Hello guys
I am new on this Forum. I am working with Oracle Discoverer and I will like to know how I can connect from Oracle Discover Administrator 4.1, to a non-Oracle database (on Microsoft Access or Dbase).
Please help me
Thanx.

hello,
to connect to a non-oracle datasource, you have to use OCA which
leverages ODBC for that connection. this happens when the report
is executed in the engine, no matter if it is run in client
server or web. if you run it via web, you have to have the ODBC
drivers installed on the SERVER, of course !

Non oracle database

Hi
Can i use micro soft access as non oracle database...if so how?
i tried to do it..it is asking me for the connectivity details,such as schema....etc..
Thanks,
kiran.

It is possible to write your own code in all the transactional triggers in a form (like on-select, on-fetch, on-update, etc.) I have only done that once, using dbms_sql calls to an Oracle server, and it is not an easy task. But once you do your first form, others would be easier.
I am not sure what type of calls you would make to your different server, but I know it can be done.

Pagination support for non-Oracle databases?

Hi,
I just read this thread (Pagination Support on pagination support. Is there any way to get pagination with non-Oracle databases? We are using an IBM iSeries / AS/400 DB2 database right now, and we're planning to use some local lightweight database in the near future as well (probably Cloudscape/Derby or "IBM Everyplace database".)
We currently use code like this:
String sql = "SELECT art FROM Artikel art" +
            /* dynamically generated where statement is added here */
            + "ORDER BY art.artikelNummer";
Query q = em.createQuery(sql);
q.setFirstResult(firstResult);
q.setMaxResults(maxResults);If I look in the TopLink logs, I see queries like this:
SELECT ARTNR, ARALT, ARAFJ, ARXII, ARAVJ, ARXIV, ARANJ, AHGCD, ARNVJ, ARCRJ, ARARK, ARFKJ, ARTNK, ARGP1, ASGCD, ARGP2, ARPR1, ARGP3, ARPR2, AREX1, ARPR3, AREX2, ARPR4, AREX3, ARASA, ARINA, ASSCD, ARIA1, ARBAN, ARIN1, ARBAV, ARIA2, ARBAK, ARIN2, ARCES, ARIA3, ARCDT, ARIN3, ARCRE, ARIA4, ARCWK, ARIN4, ARHBH, ARIA5, ARDFA, ARIN5, ARDFG, ARIA6, ARDOS, ARIN6, AREPW, ARINN, ARFOD, ARIAS, ARFOE, ARINS, ARFOF, ARNAB, ARFOI, ARNIB, ARFON, ARNIA, ARFOS, ARNN1, ARFTA, ARNA2, ARVIV, ARNO2, ARGAP, ARNN3, ARGPT, ARNA4, ARGPD, ARNO4, ARGPA, ARNN5, ARGPO, ARNA6, ARHIS, ARNN6, ARISP, ARNIO, ARKHM, ARNNS, MAGCD, AROVJ, MTGCD, ARPL1, ARMXM, ARPL2, MRKCD, ARPL3, ARMVR, ARVKJ, ARMIM, ARV12, ARMDT, ARVVJ, ARMTE, AR#VR, ARMTU, ARZLS, ARMTM, ARIAT, ARMWK, ARAVS, MPCCD, ARNVS, ARBTW, ARFJS, ARXI2, ARG2S, ARXI3, ARE1S, ARXI4, ARE3S, ARXI6, ARIB1, ARXI1, ARIB2, ARXI5, ARIB3, AROPI, ARIB4, ARPRV, ARIB5, SZGCD, ARIB6, ARSPC, ARINO, ARSMF, ARIOS, VEAAN, ARNIS, ARSYN, ARNO1, ARVR1, ARNA3, ARV1S, ARNN4, ARVR2, ARNO5, ARV2S, ARNIN, ARVR3, ARNOS, ARV3S, ARP1S, ARTFA, ARP3S, ARTFG, ARS12, ARUVC, ARZLD, ARUCW, ARAJS, ARBKV, ARCJS, ARVVI, ARG3S, ARVVP, ARINB, VPOCD, ARIO2, VPECD, ARIO4, ARVIH, ARIO6, ARVHG, ARNBS, ARVRW, ARNN2, ARVPR, ARNA5, ARVVR, ARNAS, ARVVS, ARP2S, ARVV1, ARSVV, ARZK1, ARNJS, ARNA1, ARNO3, ARIO1, ARNO6, ARIO5, AROJS, ARE2S, ARVJS, ARIBS, ARIAD, ARIO3, ARG1S FROM ART WHERE ((((ARUVC = 'N') AND (ARHIS = 'N')) AND (ASGCD = 7)) AND (AHGCD = 15)) ORDER BY ARTNR ASC
(Yeah, I know we have too much columns in the table...)
So, no pagination in the query. As you can see, we have a mechanism in place to dynamically generate a where clause. This is because the user can set filters. The problem is, if our user sets a filter that causes the result set to be significantly smaller, the performance is way better than when he sets no filter at all. We suppose this is because the whole result set is sent to TopLink, regardless of the values of firstResult and maxResults.
We are using TopLink Essentials 2.1-10, by the way.

Hi all,
I'm trying to subclass <tt>DatabasePlatform</tt> to add pagination support for the AS/400 DB2 database of my customer. To be fair, it is not going very well so far.
The first problem is, the query Chris found by googling (Re: Pagination support for non-Oracle databases?), does not work for AS/400s version of DB2. In fact, although it is called "DB2", the database on the AS/400 system is a whole other database than the "normal" DB2 database that runs on Windows and *nix. The AS/400 DB2 simply does not have a "ROW_NEXT" function.
Another option would be to use the <b>row_number() over()</b> mehtod. But, as can be read here, this function is only available from version V5R4 of OS/400. And guess what? We're stuck on V5R3 at this client. (We cannot upgrade, because there's an application in use that's written in Delphi and IBM dropped the Delphi binding from V5R4...)
So I pretty much ran out of options. On the mailing list I linked to above, someone mentions the option to make a sort of stored procedure that generates a row count number. An example of how to do this can be found here. I implemented it, and ended up with this code:

            printer.printString(") AS R WHERE R.CNTR >= ");
            printer.printParameter(DatabaseCall.FIRSTRESULT_FIELD);

            //returning false is ok as there is no connection management requirement
                //If there is no ping sql then we can not perform the ping.
            return false;
        PreparedStatement statement = null;
        try{
            sessionForProfile.startOperationProfile(SessionProfiler.ConnectionPing);
            if (sessionForProfile.shouldLog(SessionLog.FINE, SessionLog.SQL)) {// Avoid printing if no logging required.
                 sessionForProfile.log(SessionLog.FINE, SessionLog.SQL, getPingSQL(), (Object[])null, null, false);
            statement = connection.prepareStatement(getPingSQL());
            ResultSet result = statement.executeQuery();
            result.close();
            statement.close();
        }catch (SQLException ex){
            try{
                // Had to add this check because of NullPointerExceptions
                // (maybe a bug?)
                if(statement != null){
                    //try to close statement again in case the query or result.close() caused an exception.
                    statement.close();
            } catch (SQLException exception2) {
                //ignore;
            return true;
        }finally{
            sessionForProfile.endOperationProfile(SessionProfiler.ConnectionPing);
        return false;
}(As you can see, I had to override the <tt>wasFailureCommunicationBased()</tt> method as well, due to some unexpected NPE's. (A bug, perhaps?))
This code does work. However, the performance is not very well. The first page comes relatively fast, but as you browse further in the table, each page comes slower. I assume this is because the counter() method has to be evaluated for each row in the table.
I have to get the performance better and constant. Does anyone have an idea how to optimize this further?

GLOBAL VARIABLES FOR NON-ORACLE DATABASE

What is the alternative of global variables in Form 5.0 when using non-oracle databases. I know one way is passing parameters, is there any other way? I have few variables which need to be global in my application.
Thank you

There is no other way.. you have to use either Global variables or parameter lists to pass values from one form to another form.. With in the form you can always use null canvas item to store and pass values in different program units or triggers..

Connectivity to non-Oracle database sources

I have information on a seperate MS Sql Server that I would like to create a connection in OWB to connect to.
In one of the tutorial is mentions connections to a "non-Oracle database".
Does anyone have the process of how to connect from OWB to SQL Server that resides on a different server?
Thanks,

On what platform (operating system) you installed OWB control center (target database) - Windows or Unix?
In case of Unix look at this thread
Re: SQLServer access from AIX Warehouse builder
If you use Windows configuration will be simpler (all steps should be performed on server with target database/OWB Control Center).

How many users/ schemas can we create in an oracle database?

How many users can we create in an oracle database? Or how many users can oracle handle?
Problem-
I have to store information of ontologies (I will use countries instead) in db.
I have to store information regarding countries.
I have 13 tables in all to maintain for each country.
Now there are two approaches:
1) keep only 13 tables. Have an extra column in each table to indicate that a particular
row stores information for which country.
2) create a new user/ schema for each country. So we can get rid of the extra column
needed in 1st approach.
I have used the second approach. This is because number of entries in each table for a
given country will be large.
So initially when the s/w is installed I create a central-user. Each time data for new
country has to be entered central-user creates a user/ schema, and creates tables for
this user/ schema. The central user can access the tables of all the countries by
country_name.table_name. By this approach I believe searching would be easy.
If there is any flaw in my approach kindly mention it.
Thank you

There is no (practical at least) limit to the number of users & schemas you can have in Oracle.
Your approach, however, is not going to scale nearly as well as the first option you outlined (adding a column). You are going to end up caching every possible variation of the various queries you're going to be executing because you will be referring to so many different tables, which is going to mean that you are doing a lot more work to parsing statements and generally churning through the shared pool. If you create enough users, you're liable to start hitting ORA-04030 errors because your shared pool is so fragmented.
Additionally, you're likely going to end up with a whole lot of dynamically generated SQL to accommodate new schemas getting added over time which is going to cause you even more pain. Figuring out dynamically what table to join in is a heck of a lot more difficult for the programmer to write and for the database to handle than simply passing in a different country code.
If you're concerned about having too much data, you can have your cake and eat it to by adding the country column and partitioning the tables based on country.
Justin
One other item I forgot to mention is maintainability. Having dozens or hundreds of "identical" schemas makes maintenance a huge pain because something like adding a new column now requires dozens or hundreds of separate DDL statements. You're almost guaranteed that some schema isn't going to be in sync-- it's going to miss a column or miss an index, etc.

Problem about using Oracle Form 6i to connect Oracle Database 10g express.

Sorry to interrupt all of you.
I have encountered a problem about using Oracle Form 6i to connect Oracle Database 10g express.
As I would like to
I use Oracle Net8 Easy Config to create a connection.
According to "tnsnames.ora", the paramater of connection is as follows;
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
(CONNECT_DATA = (SID = XE))
Unfortunately, when I use Oracle Net8 Easy Config to test the connection, an error message is prompted as follows:
Connecting....
The test did not succeed.
ORA-03106: fatal two-task communication protocol error
There may be an error in the fields entered
or the server may not be ready for a connection.
You can check the server and retry, or continue.
After I google it, I still have no idea how to solve the problem. I would like to ask, could anyone mind providing some hints or solution to address the issues.
Thanks for your assistance in advance.

I don't believe the Net8 Easy Config (NEC) will create a compatible entry in the tnsnames.ora. I have Forms 6i running successfully against a 10g Express database, but I did not use the NEC - I created the entry myself. Here is the entry I use:
XE=
(DESCRIPTION=
    (ADDRESS=
      (PROTOCOL=TCP)
      (HOST=<<servername or IP address>>)
      (PORT=1521)
    (CONNECT_DATA=
      (SERVER=dedicated)
      (SERVICE_NAME=XE)
)Hope this helps,
Craig B-)
