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

Can SCAN be used for non 11gR2 databases ?

I am in the processes of database consolidation phase, where in I am consolidating 15 server to a 6 node single Grid for RAC , non -RAC & RAC one node.
I have non -RAC standalone database on NFS mount , visible on all the 6 nodes , idea is to be able to start the db from any node I like for maintenance which I can do with RAC & RAC ONE NODE.
I am planning to run SCAN on 3 node , but the question is, can I use SCAN listener for all the databases ?.
Currently started with a 2 node cluster where I have 11gR2 and couple of RAC one nodes and a 10g rac .
I am able to point to scan LISTENER and able to connect to 10g db , to me SCAN looks very pomissing for our kind of environment where db's can run on any node with out impacting client changes.
Before I present this to the management which I am planning to do This Thursday ( big day for me as I am projecting to save quite a bit of money ).
I don't want to push some thing that's not going to work , even thoug I can prove it now that it works.
And more importantly I have not see a document in google or ORACLE support that says I can nor a sign that any one using for non 11gR2.
How is this SCAN compared to OID or SUN OPEN DS ?

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.

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:

            //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{

        }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,

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..

How to use a non-Oracle database?

Oracle Lite is used as the database per default. Technical
notes describe how to use Oracle 9i. I'm more interested in using more light-weight RDBMSes like HSQLDB for example. It is been said that Oracle BPEL supports Oracle, Oracle Lite, DB2, SQL Server and Pointbase. Now how to configure Oracle BPEL to use each of the non-Oracle datbases listed above?

I've managed to setup the PM to use Pointbase rather than the default Oracle Lite. Along the way, several questions came up:
1. Since the directory system\database\scripts already provides DDL scripts for Pointbase, creating the tables of a Pointbase database was easy. However, I wonder why you don't support HSQL. After all, OC4J supports HSQL data sources (see database-schemas\hypersonic.xml). Are there any features required by Oracle BPEL that are not provided by HSQL? If not, can we just use the Pointbase DDL scripts for HSQL?
2. Editing the data-sources.xml file also wasn't a big deal although templates for Pointbase were missing. BTW, my XML editor reports the data-sources.xml file to be invalid: "Document cannot be stand-alone because default-value attribute 'connection-retry-interval' is not explicitly assigned.
3. The changes in StartOraBPEL.bat were:
- Comment out running kill_olite.bat and start_olite.bat
- Start the Pointbase server (rather than Oracle Lite)
4. The needed changes in obsetenv.bat were not that obvious: It was required to add the Pointbase libs to the BOOT_LIB classpath. Otherwise the Pointbase driver cannot be loaded. To be on the safe side, I've also added the Pointbase libs to the MY_CLASSPATH classpath but I'm not sure if that is really required. Is it?
5. Finally, it would be good if shutting down the Pointbase server could be done in a similar fashion as that is configured for Oracle Lite. Apparently, some sort of hooking is used. Now how to setup a shutdown hook for a Pointbase server?

Alert Categories - Can they be used for Non-BPM scenarioes?

Hi experts,
I have a quick question and it's regarding the question I posted yesterday on:
How do I configure an auto-email alert for Adapter engine errors
Will I be able to send alerts for Adapter Engine errors (Through the use of Alert Categories), if I am not using BPM?
Please advise.
Thanks.

Hi,
From your answer, can I confirm that alerts I defined in ALERTCATDEF can be used by for Non-BPM interfaces?
The essential difference between BPM and Non-BPM alert triggering is BPM allows a control step to trigger an alert.
Please correct me if I'm wrong.
Thanks.

Can JDeveloper be used for developing code for deployment to production?

Hello,
I've downloaded JDeveloper and wanted to know if I could use it for developing code that is deployed to production? I looked at the licensing terms and nothing there seems to say I can't do that. Am I missing something? Also on the JDeveloper page, it says "Free download". Is this tool like SQL Developer - truly free?
Thanks
Alex

http://www.oracle.com/technology/products/jdev/htdocs/jdeveloper11gfaq.html#L0
JDeveloper is totally free, you can use it for production. However, some libraries come with JDeveloper, such as ADF, are not free and you have to pay for them in order to use them in production.

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.

Configuration Managment Pack for Non Oracle Systems (new)

Hi ,
There is a pack called "Configuration Management" for the database. This pack manage hardware , software , updates, patches, etc for host that have installed any Oracle Software.
Now, in EM Release 2 there is a new pack "Configuration Managment Pack for Non Oracle Systems" wich basically will allow me to the same but without the requirement to have any Oracle software installed.
The question is : Where can i find a white paper about it? i been looking around and there is only mentions of the product, but not extra info. I know is out already 3k p/processor..
Any ideas?

WS-X6348 Module use for non-POE?

We have two WS-X6348 48-port RJ-45 power-over-ethernet (POE) cards in our 6509 switch. We do not need to use these cards for POE. Can they be used for non-POE devices without any problem? Does the card have to be configured as such? We are worried about damaging equipment (non-POE device, the WS-X6348 card or the 6509 chasiss itself).
Can anyone render any advice relating to this?
Thank you!
Frank Nye

While you can use the WS-X6348 card with Non-PoE Device, I would also take a look at the power consumption of this module, so you can provision your power supply accordingly.

Multi Database Support: TimeQuery setting for non-oracle

Hello,
I wanted to develop ADF Application which is database-neutral and thus SQL92 type application.
I actually wanted to make sure that my application runs fine at least on MySQL DB. Therefore I set up my connection in JDeveloper to Mysql database but I started facing issues while working with it. See this > Re: [ADF-11.1.2] Non Sense Associations and View Links while using Mysql as DB
Also there's some limitation while working with non-oracle database like : JDeveloper can't recognize primary key column, therefore developer has to manually select primary key attribute in each EO.
Therefore, I thought to use Oracle DB to overcome from above issues and with Application as SQL92 type.
Information to share, if applicable to you as well:
1. database-neutral SQLs: It may not be possible to come up with CREATE TABLE SQL statement which is database-neutral. i.e. You have to modify SQL scripts generated from Oracle Database Model to make it work with other database. This I think is difficult part, but with proper care and with the help of tool, you can achieve the CREATE SQL statements for other database.
2. Under Model.jpx file of Model project, you can then add your non-oracle Database to test your application with. But make sure you select Oracle Connection while developing/changing Model layer of project << This is again because i think Jdeveloper has some issue with non-oracle Database (mentioned above)
3. Under bc4j.xcfg file (right click AppModel > Configurations...), you properly set value of "sql92 Db Time Query" (jbo.sql92.DbTimeQuery) property . For e.g. default is "select sysdate from dual" which is compatible to oracle database to fetch the current date from database. However this doesn't work with MySQL. You need to set it as "select now()as CurrentDateTime" if you are using MYSQL. This is require if you are using History Column on EO (I don't know if it is require for other purpose of not!) . Following is the code of bc4j.xcfg, notice "jbo.sql92.DbTimeQuery" property.
<?xml version = '1.0' encoding = 'UTF-8'?>

Questions:
1. How would I make "jbo.sql92.DbTimeQuery" work with other database. It seems I have to hard code the value of it. Can't we externalize it so that we can set it dynamically ?
2. I am sharing this what I noticed and which is not yet documented (at least I haven't found it anywhere)... please let me know if you are aware of any setting needs to be done which may not be documented ?

Did you ever find out more information about working with Dates in non-oracle databases?

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.
