ADF with non Oracle databases?

HI all,
I would like to know, if there are people using ADF but without Oracle database. We are negotiating a new project, and I would IIke to develop it with ADF, but database will be Firebird or Postgres.
I know its possible, but Im searching experiences of using ADF mainly with other databases, and if its worth for this kind of project, or otherwise,if there are so many "changes" not using Oracle db.
Regards.

XML Publisher with Non Oracle databases

Hi,
Can we use XML Publisher with non oracle databases like Postgres ,mySQL etc.

Hi
Not sure if you're talking Apps or non but you can do it equally with both. Check out the Data Engine in the user guide and look for Distributed Queries. XMLP will need a jdbc connection to the db but you can then pass a query and get XML back.
You can even write one query to pull back say customers from Oracle and their invoices from MySQL, you'll get a merged data set back with a master detail relationship btw customers-invoices

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:
package com.myclientsname.persistence;

import java.sql.ResultSet;
import java.sql.SQLException;
import org.eclipse.persistence.expressions.ExpressionBuilder;

    private static final long serialVersionUID = 0L;
    public AS400Platform(){
         super();
         super.setShouldBindAllParameters(false);
    public void printSQLSelectStatement(DatabaseCall call, ExpressionSQLPrinter printer, SQLSelectStatement statement) {
        int max = 0;
        int firstRow = 0;
        if (statement.getQuery()!=null){
            max = statement.getQuery().getMaxRows();
            firstRow = statement.getQuery().getFirstResult();
        if ( !(max>0) && !(firstRow>0) ){
            super.printSQLSelectStatement(call, printer,statement);
            return;
        } else {
            statement.setUseUniqueFieldAliases(true);
            ExpressionBuilder builder = new ExpressionBuilder();
            statement.addField(builder.getField("COUNTER() AS CNTR"));
            printer.printString("SELECT * FROM (");
            call.setFields(statement.printSQL(printer));
            printer.printString(") AS R WHERE R.CNTR >= ");
            printer.printParameter(DatabaseCall.FIRSTRESULT_FIELD);
            if ( max > 0 ){
                // Use of binding parameters is not allowed here, so use
                // String concatenation instead...
                printer.printString(" FETCH FIRST " + max + " ROWS ONLY");
        call.setIgnoreFirstRowMaxResultsSettings(true);
    public boolean wasFailureCommunicationBased(SQLException exception, Connection connection, AbstractSession sessionForProfile){
        if (connection == null || this.pingSQL == null){
            //Without a connection we are unable to determine what caused the error so return false.
            //The only case where connection will be null should be External Connection Pooling so
            //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?
Best regards,
Bart Kummel

Configuration of XSQL for use with non-Oracle dbs

If anyone has positive experiences with configuring XSQL for use with non Oracle databases I'd like to hear how they did it, see tutorials, configuration files, etc.
Specifically setting up to use MySQL or Postgresql on Linux/FreeBSD would be very interesting.
Also, does anyone use this without setting mime types? How would you go about this so you could point to the relevant servlets in the page?
Josh

I don't understand how setting up for Non-Oracle DB's is related to not setting up the servlet as an extension-mapped servlet.
It might work, but would you run JSP's
that way? XSQL behaves very similiarly
inside to how a JSP runner works, which
wants to be servlet-mapped.
However, OAS 4.0.8.1 does not support
extension mapping and XSQL works there
so i'm assuming it would work on other
servers set up that way. It's not
a configuration we test/certify.

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 !

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?

12282,
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 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

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
null

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..

Jdeveloper Team RE Jdeveloper 9.0.3 For Non-Oracle Databases

I see that support for non-Oracle databases and Third-Party JDBC drivers is very improved. However, I have tried to use the SAPDb JDBC driver and the BC4J tester and generated Swing clients all display greyed so that no updates are possible. This appears to be a bug since Jbuilder works fine with this driver. However, I think Jbuilder's Express dataset and commit philosophy is really bad. Any commitments as to when this will be fixed?

Yes, I examined the attribute settings and manually adjusted them in the entities and views. They are now updateable. Using Jdeveloper with SAPDB would be very tedious. Jdeveloper did not recognize foreign key constrains, primary keys, nor that attributes were updateable.
Is there a way to include SAPDB in the testing? It is trivial to install and run and would make Jdeveloper a more robust tool. I do not like Jbuilder's approach to master-detail client screens and would recommend using Jdeveloper for this type of work if it could handle more databases like SapDb.

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).

CURRENT_TIME and non-Oracle Database

Folks !
When I use CURRENT_TIME in JPA named query, TopLink (Essentials) translates it into a "sysdate" function - this doesn't work on non-Oracle database like Postgres.
How do you get Toplink to substitute correct function for non-Oracle Database ?
thanks,

I set following in my persistence.xml:
<property name="toplink.target-database" value="PostgreSQL" />
Still no luck.

What is possible with non oracle components in the EMGC 10g release 3

Hello,
What is possible with non oracle components in the EMGC 10g release 3
Our customer wants to also monitor and maintain non oracle components with EMGC 10g release 3.
Some non oracle components are:
Routers,
Firewalls,
Application Servers,
Switches,
Mail Servers,
DNS/DHCP servers,
Print Servers,
File Servers,
NTP,
Citrix,
Terminal Server,
Lotus Notes,
Etc etc.
Is there a document on which non oracle components can be monitored in the EMGC and what can be maintained with these components?
Regards,
Tim Abdoelhafiezkhan

Take a look into Plug-ins, there are some none-oracle ones pre built by Oracle and others.
There's a forum about Extensibility in the current category here.
Also, for further extensibility, the new Connector Framework looks interesting, see the OEM Integration Guide.
