Build gui for existing oracle database tables with webdynpro java?

hi
i want to build a GUI to maintain existing oracle tables
so far we used oracleFORMS to do so
is there a good approach for webdynpro java? or do you recommend other sap tools?
can we generate the gui with a wizard based on the fields in the table?
do we have to generate sql statements or type in manually?
regards
joerg

Hi Joerg,
generally that is possible, but you'll have to implement the data access by yourself, by means of EJB or another Java persistance framework such as JDO, SQLMaps, Hibernate, whatever...
Web Dynpro allows to build a GUI based upon a model - in this case this could be some POJOs (DTOs) representing your database tables, which are communicated to the GUI by your data access layer. Consider a model as a simple Java bean representing database data.
This approach would require to build a data access layer which incorporates manually generated sql statements, so you'll have to have expert database and java knowledge.
There might be other approaches, this is just to demonstrate one working possibility.
regards,
Christian

Can you be more specific ? Are you talking about the backend table or the table that you wanna publish on the portal (through your JDBC web dynpro project) ...

Oracle database integration with SAP PI for high volume & Complex Structure

Hi
We have requirement for integrating oracle database to SAP PI 7.0 for sending data which is eventually transferred to multiple receivers. The involved data structure is hugely complex (around 18 child tables) with high volume processing requirement (100K+ objects need to be processed in 6-7 hours). We need to implement logic for prioritizing the object i.e. high priority objects must be processed first and then objects with normal priority.
We could think of implementing this kind of logic in database procedures (at least it provides flexibility for implementing data selection logic as well as processed data can be marked as success in the same SP) but since PI sender adapter doesn't support calling Oracle stored procedures currently so this option is rules out. we can try implementing complex data selection using oracle table function but table function doesn't allow any SQL query which changes data (UPDATE, INSERT, DELETE etc) so it is impossible to mark selected objects in table function from PI communication channel "Update Query" option.
Also, we need to make sure that we are not processing all the objects at once as message size for 20 objects can vary from 100 KB to 15 MB which could really lead to serious performance issues for bigger messages.
Please share any implementation experience for handling issues:
1 - Database Integration involving Oracle at sender side
2 - Complex Data structures
3 - High Volume Processing
4 - Controlled data selection from database to contro the message size in PI
Thanks,
Panchdev

Hi,
We can call the stored procedure using receiver adapter using ccBPM, we can follow different approaches for reading the data in this case.
a) In this a ccBPM instance needs to be triggered using some dummy message, after receiving this message the ccBPM can make a sync call to the Oracle database the store procedure(this can be done using the specific receiver data type strucure), on getting the response message the ccBPM can then proceed with the further steps.The stored procedure needs to be optimized for improving the performance as the mapping complexity will largely get affected by the structure in which the stored procedure returns the message.Prioritization of the objects can be handled in the stored procedure.
b) In this a ccBPM instance can first read data from the header level table, then it can make subsequent sync calls to Oracle tables for reading data from the child tables.This approach is less suitable for this interface as the number child tables is big.

TimeZone.getDefault().getID() does not exist in your Oracle database table V$TIMEZONE_NAMES???

Hi Everyone,
My Jdev version is 11.1.2.3.0.
I have developed many ADF applications in this version itself by setting time zone as -Duser.timezone="+05:30" and all were running fine.
But Jdeveloper got crashed so i reinstalled the same version but now none of the applications are running.
Its showing error as below:
oracle.jbo.JboException: JBO-29112: The time zone 'GMT+05:30' defined in adf-config.xml or TimeZone.getDefault().getID() does not exist in your Oracle database table V$TIMEZONE_NAMES. Please set an available time zone in your TZ environment variable or user.timezone Java system property.
What to do now?
how will i know wat time zone should be set?
please help the needful...
Thanks.

Unable to Create Entity Model from existing oracle database

Hi,
I am using Visual Studio 2013, .net framework 4.5, entity framework 5.0 and oracle 11g database.
Issue Description: I need to develop WCF service to exposing the account information which needs to get the data from 20 oracle tables. Trying to create entity model from existing oracle database. first i tried creating just two tables it
was created but it took more than 30 minutes. then i selected remaining few tables it took more than a days but nothing created just showing spinning the wheel. then i tried with fresh project and selected all the tables but same issue nothing created and
also there is no error. during this process i checked database query monitoring there is a big sql statement collection tables metadata. i don't know what was wrong the query taking too much time to complete the process.
we tried multiple machine and different oracle database all are same issue.
Sql server database -looks good no issues.
Any help/tips/ideas welcome to overcome this issue.

Hi Sakthimp,
Welcome to MSDN forum.
Your issue is out of support range of VS General Question forum which mainly discusses the usage of Visual Studio IDE such as
WPF & SL designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help System
and Visual Studio Editor.
Because your issue only occurred with oracle database, moreover Oracle developed the Entity Framework for Oracle itself, I suggest that you can consult your issue on Oracle forum/community:
you will get better solution and support there.

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;

            max = statement.getQuery().getMaxRows();
            firstRow = statement.getQuery().getFirstResult();

            super.printSQLSelectStatement(call, printer,statement);

        } else {

            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");

            //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

Hello Anybody, I have a question. Can any of you please suggest me how to make an xml file from the database table with all the records?

How to import the data in a .xls or .xlsx file into a oracle database table

Hi,
Please tell me how to import the data in a .xls or .xlsx file into a oracle database table in Oracle 10gR2 using Oracle Warehouse Builder 10gR2.

....can we do something through Non-Oracle->ODBC?Yes, it is possible, look at this thread
[SQLServer access from AIX Warehouse builder|http://forums.oracle.com/forums/thread.jspa?messageID=2502982]
If your server (with target DB and OWB runtime) is on Windows OS this configuration will be simpler - you can use single server.
And additional link on OWB blog (with 11g transparent gateway)
[http://blogs.oracle.com/warehousebuilder/2008/01/11g_heterogeneous_agent.html]
(configuring nonoracle connection with 10g generic connectivity very similar to 11g gateway)

Error when installing 9.0.1.4.0 patch set for the Oracle Database Server.

Hi to all.
Currently, i am trying to install patches for portal server.
The server OS is Sun Solaris 8.
We are using Oracle9iAS.
Now, we are installing 9.0.1.4.0 patch set for the Oracle Database Server.
We managed to install the patch, but have problem with the Post Install Action.
We managed to run
-ALTER SYSTEM ENABLE RESTRICTED SESSION;
-@rdbms/admin/catpatch.sql
-ALTER SYSTEM DISABLE RESTRICTED SESSION;
-CONNECT / AS SYSDBA
-update obj$ set status=5 where type#=29 and owner#!=0;
-commit;
But, when we come to the next command, which is to shutdown, it gives us like
this..
SQL> update obj$ set status=5 where type#=29 and owner#!=0;
1402 rows updated.
SQL> commit;
Commit complete.
SQL> shutdown immediate
Database closed.
Database dismounted.
ORA-00604: error occurred at recursive SQL level 1
ORA-01219: database not open: queries allowed on fixed tables/views only
We tried to startup the database..it gives us this error..
SQL> startup
ORA-01081: cannot start already-running ORACLE - shut it down first
So, we tried to shutdown again..
SQL> shutdown immediate
ORA-01089: immediate shutdown in progress - no operations are permitted
I been informed that this is maybe a Database problem related. Any ideas?
Best Wishes,

The easiest way to export Oracle data to Excel is to use sql developer. It is a free download and this article by Jeff Smith shows how easy it is

And One Last Thing
Speaking of export, sometimes I want to send data to Excel. And sometimes I want to send multiple objects to Excel – to a single Excel file that is. In version 3.2.1 you can now do that. Let’s export the bulk of the HR schema to Excel, with each table going to it’s own workbook in the same worksheet.

HOWTO Transfer Oracle Database Tables to SAP

hi
I need to import some Oracle Database Tables to the SAP Dictionary, i was wondering that id there is a short way to do this. If there is a progrm to be written then could any one send me the code.
And if there is another way then plz do guide me.
Thanx in Advance.
Zahid

Dear vasmi VaraPrasad!
I am grateful for ur time. I perfectly understand the logic you told me.
Now let me tell you what i have done so for in this regard by doing some googling and with the help of my respected teacher.
I made a connection entry in the DBCON table and specify all required things
like
     NAME      = MYCONNECTION
     DBMS      = ORA
     USER      = SABRO <my db user>
     PASSword = *********/********* <my db password>
     INFO      = FIRS <TNS Name to my db>
afte that i tried the following code.
===========================================
REPORT Z_DB_1 .
*Declaration
DATA: WA TYPE <SAP_TABLE>.
Init connection
EXEC sql.
connect to 'MYCONNECTION' as 'MYDB'
ENDEXEC.
Open connection
EXEC sql.
SET CONNECTION 'MYDB'
ENDEXEC.
Do your trick
EXEC sql PERFORMING your_form.
SELECT * INTO :WA FROM <DB_TABLE>.
ENDEXEC.
Stop connection
EXEC sql.
disconnect 'MYDB'
ENDEXEC.
FORM your_form.
WRITE: / wa-deptno, wa-dname, wa-loc.
ENDFORM.
======================================================
now when i run this program it terminates with a runtime error that is:
"An error occured while setting up a connection to MYCONNECTION".
This seems that there is some problem with the connection i don't know how to figure out what is wrong with this connection.
I think the problem is that SAP does not know the TNSNAMES file, or there might be some environment variables to be set so that SAP recognize or read that TNS NAME "FIRST".

Zahid Kareem.

How to load text file data to Oracle Database table?

By using Oracle Forms, how to load text file data to Oracle Database table?

Metalink note 33247.1 explains how to use text_io as suggested by Robin to read the file into a Multi-Row block. However, that article was written for forms 4.5 and uses CREATE_RECORD in a loop. There was another article, 91513.1 describing the more elegant method of 'querying' the file into the block by transactional triggers. Unfortunately this more recent article has disappeared without trace and Oracle deny its existence. I know it existed as I have a printed copy in front of me, and very useful it is too.

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

Select data from database tables with high performance

hi all,
how to select data from different database tables with high performance.
im using for all entries instead of inner joins, even though burden on data base tables is going very high ( 90 % in se30)
hw to increase the performance.
kindly, reply.
thnks

Also Check you are not using open sql much like distict order by group by , use abap techniques on internal table to acive the same.
also Dont use select endselect.
if possible use up to n rows claus....
taht will limit the data base hits.
also dont run select in siode any loops.
i guess these are some of the trics oyu can use to avoid frequent DATA BASE HITS AND ABVOID THE DATA BASE LAOD.
