Registering Repsvr8 control in oracle 8i Lite

hi,
I'm developing an application wherein I've to connect to Oracle 8i Lite database for Windows CE. I'm using Windows CE toolkit for Visual C++ version 2.0 on Windows CE based palm device. I'm in confusion of how to connect to 8i Lite Database. Are there any ActiveX controls given in 8i Lite.if so how to register in the device and how to use

I saw the table EMP is under the owner of SYSTEM.
Try to use 'Select * from system.EMP;'
regards,
Barry

Oracle 10g Lite Mobile Devices

Hi,
1. Does Oracle 10g lite Support Arabic?
2. Does Oracle 10g lite Support Windows Mobile 5.0, PPC 2005?
3. On a PPC 2003 OS the sync worked well but after it finished the device manager started to register the device on the mobile server, there is an error raised that has invalid error code and as description 'Insufficient information to proceed',
Help Me In That Please?

Hi,
ad 1: Oracle Lite should support all the charsets the "big" Oracle server supports - even unicode afaik.
ad 2: yes, OLite supports WM5 (you have to install a patchset from metalink to enable WM5 support - try to search previous threads)
ad 3: what is the regional settings of your device? if it's some arabic culture which is not present in default OLite installation, you'll have to make some changes into Oracle Lite system tables to support your platform. In OL10g the "platform" is defined as a combination of OS type, CPU type and current OS culture settings - for example something like "WM5 + XScale CPU + czech culture". I used something like this to replace all the japanese platforms with our language to enable support for devices wit czech locale settings:
UPDATE mobileadmin.dm$all_platforms
SET NAME = REPLACE(NAME, ';JA', ';CS'),
TYPE = REPLACE(TYPE, '_JA_', '_CS_')
WHERE NAME LIKE '%;JA';
INSERT INTO mobileadmin.DM$LANG_MAP
(LANG_ID, LANG_NAME, LANG_CODE, LANG_REG, CODE_PAGE)
VALUES
('CS', 'Czech', 'CS', 'CZ', '1250');
you'll than probably also need to copy some files from default US locale to your new locale directory:
{ora10gLiteR2}\mobile_oc4j\j2ee\mobileserver\applications\mobileserver\setup\us => {ora10gLiteR2}\mobile_oc4j\j2ee\mobileserver\applications\mobileserver\setup\{your_locale}
than the device should be able to get registered...

Some doubt regarding oracle 9i lite

Hai,
I am doing R @ D on 9i lite. My scenario is as follows,
1. first i installed oracle 8i 8.1.7 database.
2. using oracle 9i lite 5.0.2 setup, In another machine instllaing mobile server and mobile development kit.
3. how to synchronize the 9i lite database with my 8i database.
My scenario is i need to create a standalone mobile server environment.
help me.

Your environment is older versions than we use, but the basic process for creating oracle lite client databases synchronised with the main server database is as follows
1) install the mobile server following the installation guide.
This will create the mobile server repository (schema MOBILEADMIN) and application on the app server or standalone. For production the repository data would normally be a seperate schema in the main database, and the mobile application running on one of the app servers
2) next you need to create your 'application'.
This consists of defining the tables or views from the main system you want to be able to synchronise with the offline clients. If you are just starting, the easiest way is to use the wtgpack wizard that comes as a part of the development kit. Start this up, create an application name, specify the client environment it will be going to (eg: WIN 32 or PPC2003) do the connection to the main server schema, select a table from the main system you want to synchronise, and take it through to publish
For the first go to see it working i would advise keeping it simple and just picking a small table, and set the refresh option to complete, with server wins in the conflict resolution. Once you have got things working, you can then go back and add other tables and start to look at using thre data subsetting to select only data relevant to a particular client, fast refresh options, and using views from the main system as the basis for the snapshots (in 5.0.2 i would avoid sequences)
3) when the application is published, start up the mobile manager tool
you should now be able to see the application you created, and the publication items (the tables that will be synchrionised). You now need to go to users and create a user and associate them with the application
4) set up client device
on a device of the type you want to synchrionse with (we use PDAs), go into IE, and enter the mobile server URL/webtogo/setup. This will give a list of the downloadable clients. Pick the appropriate one and follow the install instructions, using the user/password set up above
5) synchronise
on the client device run the msync utility. This will ask you for the user name/password and the server url, enter these and press the sync button and two datyabase files (.odb) should be created on the client - a control one concli, and one with the same name as your application. The client set up should have also installed a utility msql that you can use to look at the new local database

Oracle 10g Lite with ADF/BC4J Application(Offline access in Mobile )

Hi All,
We have the following requirement from one of our client.
Customer Company has R12 Apps instance(which is having 10g Database APPSDB). The users will come in the morning
and connect to the System(NEWSYSTEM) to download their daily worksheet(resides in APPSDB) to their Mobile Devices
(Windows XP - http://www.keenzo.com/zoom.asp?zoom=3830134) and then disconnect from the system. The download of data
should start after login into their Mobile Device Custom Application So that only their worksheet will be downloaded
to their Mobile Device DB.
Then they will goto their fields and review their daily worksheet in the Mobile Device application(NEW APPLICATION)
in offline mode. And update in the application with their findings, which should be stored in the Mobile Device database(MOBILEDB).
In the evening the uses will come and connect to the system(NEWSYSTEM) and login into their Mobile Application and
start the upload process, then the updated data from their Mobile Database will be uploaded into APPSDB via the NEWSYSTEM.
I checked the links, http://www.oracle.com/technology/products/lite/index.html and http://lite.us.oracle.com and I have
got some understanding about Oracle 10g Lite. For the above requirement we are proposing the NEWSYSTEM as Oracle 10g Lite Server
and the NEW APPLICATION as ADF/BC4J which can run in their Mobile Devices(work offline and then sync with DB).
I have the following questions.
1) The above proposing system is feasible?
2) Can we develop the Mobile Application using ADF/BC4J and using that we would like to
control the sync process from our custom application.(so that only their worksheet will come to their Mobile Device DB)
3) If I want to have the above system,
a) I should have Oracle 10g Lite server installed(im Unix or Windows)
b) I should have Oracle 10g Lite client installed in a Windows PC/Laptop
c) To get my custom application in My Mobile Device, first I have to deploy the application
in Oracle 10g server using Oracle Mobile Server. Then I have to connect my Mobile Device to the Oracle 10g Lite server,
and deploy the application in my Mobile Device using Oracle Mobile Manager.
4) I would like to do a POC before start the project.
What are all the installations I have to do in my Laptop.(Consider I am installing Oracle 10g Lite server/client, Mobile Manager in my Laptop)
I am new to Oracle 10g Lite, correct me if any of my understanding is wrong.
If you have any comments in the approach please add it.
Thanks in advance.
With Regards,
Kali.

1) The above proposing system is feasible?
perfecly feasible, and actually a reasonably standard use of oracle lite
2) Can we develop the Mobile Application using ADF/BC4J and using that we would like to
control the sync process from our custom application.(so that only their worksheet will come to their Mobile Device DB)
Actually two different questions here. The application code that runs on the client device can be written in any thing that will run on that type of device, and is capable of using the APIs to connect to the local database, and the other functionality like synchronisation. From the forum there look to be VB, C, java users out there (an i even believe if you wanted to, you could use forms). Main decision regarding the Platform for the application code development tends to be whatever you have the skills in.
In terms of the sync process only downloading a particular users worksheet, this would be defined when you define the snapshots of the database tables you want to download, rather than the sync login process itself.
For example - you have a table WORKSHEETS on the server that you want to download, it has a column EMP_NO which is the employee identifier. You would define the selection for the snapshot as
select * from WORKSHEETS where EMP_NO=:emp_no (note the bind variable)
when you then add users to the oracle lite application (actually the database), then you will have a parameter called EMP_NO to define with the employee number for that particular user, and this will be used automatically as the bind variable in the download.
NOTE subsetting in this way does not need to be direct, for example things like
select * from TASKS where id in (select task_id from user_tasks where emp_no=:emp_no) is perfectly valid
NOTE when reading the forum and documentation, be careful of the word application. There are actually two different things to be developed, both normally called 'application'
Within oracle lite you create an application with publication items, scripts, sequences etc. and then subscribe your users to this application. The application in this context is actually the database and synchronisation management ONLY (you can include files and code for download)
The second application is your runtime code that has a user interface, functionality, processing and validation. This is written in some development platform, and accesses the database created above for select, insert, update etc.
3) If I want to have the above system,
a) I should have Oracle 10g Lite server installed(im Unix or Windows)
YES this goes on the app server and installs a repository schema MOBILEADMIN within your database
b) I should have Oracle 10g Lite client installed in a Windows PC/Laptop
YES - once the server is set up, this is downloaded and set up by accessing the <server url>/webtogo/setup
c) To get my custom application in My Mobile Device, first I have to deploy the application in Oracle 10g server using Oracle Mobile Server. Then I have to connect my Mobile Device to the Oracle 10g Lite server,
and deploy the application in my Mobile Device using Oracle Mobile Manager.
steps in outline are
1) install server
2) develop the oracle lite application (ie: database) and publish this to the mobile server (can use the development kit or java APIs for these two steps
3) add a user with the relevant subsetting parameters
4) set up oracle lite win32 client on the laptop from the server download
5) synchronise using the msync utility on the client to create the databases and odbc entries
6) develop your application code using the client database
7) during development, then changes to database structure would be via changes and re-publish of the oracle lite application, followed by a sync to update the client database
8) once all development is complete, the runtime application code can be bundled up into the oracle lite application if you want, and then the initial sync for live users will download the database and application code.
4) I would like to do a POC before start the project.
What are all the installations I have to do in my Laptop.(Consider I am installing Oracle 10g Lite server/client, Mobile Manager in my Laptop)
You can set up a standalone server on the laptop, but better to do this on a development app server so you can use the main server development database as the data souce for the snapshot definitions (pretty easy install). there are conflicts if you try and put the oracle lite client and the mobile development kit on the same machine, but if you are familiar with java, the API development is fairly straightforward to use (i have developed applications in this, and i know only the basics of java) you do not need the MDK
Basic for a POC i would say is to
1) set up mobile server on development
2) define a simple oracle ite application on two server tables. one has select * from table, and the other has select * from table where .... including bind variable. at this stage use complete refresh as the mode for simplicity
3) publish the application, create user and define the subsetting variable
4) set up mobile client and synchronise user. use the msql utility to interrogate the database and check the content, and do some updates 9standards SQL syntax)
5) create simple appliaction code to conect to and read the database on the client
6) do a sync after the updates above and check they appear in the server
The above should be reasonably quick and proves
a) ability to define the data you want to be sent to the users
b) ability to create an app to manage the database running on the client device in you preferred software platform
c) data download and upload
after this basic POC, you can extend into defining fast refreshes to improve the efficiency of the sync process, managing the MGP process, developing a more comprehensive database and application etc. If you have complex joins between server table, you may also want to look at creating views to denormalise data and use these as the basis for the snapshots

Oracle 8i Lite for CE

Does Oracle 8i Lite for CE run on the Jornada 720. This handheld is using the StrongARM SA1110 processor. The core system version is 3.0.

Hi,
I'm runing Oracle8i Lite in windows ME, and I do get the an error saying that the server is too low for this feature, but I get the SQL prompt right away after that. Maybe u should configure the password in the Oracle 8 Navigator, by selecting the new Object icon, and then register your new Database connection.
Good luck

How do I create a db in Oracle 9i Lite?

I have used Oracle 8i Lite on handheld computers in a replicated environment for quite some time now. I am in the middle of setting up a demo tablet computer, but since Oracle 8i Lite is no longer downloadable from the Oracle website, I instead downloaded 9iLite. When I went to install it, my options were Mobile Server and Mobile Development Kit. I went ahead and followed the install wizard without choosing either one of these two options, thinking I would just get the plain Oracle Lite database environment. After the install completed successfully, I went to look for Oracle Navigator and where the Polite.odb was located, but no where do these two items seem to be installed (or copied to).
Somewhere in this forum, a person posted that 9iLite needs 8iLite to be installed already in order to use the basic database functionality. Is this the case? Is there anyway to create a database using my create table script for all the tables in my db. I could see that SQL Plus is installed, which is the app I used to run the script in 8iLite.... but you already need a database to log into in order to run SQL Plus.
How do I create a database in Oracle 9iLite.
Your help is greatly appreciated.
PS: I am somewhat in a hurry, since my demo unit needs to be done by the end of the weekend..... I really did not anticipate this trouble with 9iLite.

Sure but you break the license, or forgive me and a did a mistake

How to Register a View in Oracle Applications

Hi,
I have created a Custom View and want it to see it in one of the BPA Pages. For this purpose I shall need to register the view in Oracle Applications.
Can you please provide me clues to do so. I tried the Application Developer responsibility, there I can only query the view and not register them.
Also if I try using backend I could get hold of Package AD_DD which registers a table. Any clues for registering the View would be welcome.
Thanks

Thanks for your response.
Actually I need to show Sales Order Line No, Federal Id and a few other Fields on our Invoice. Now these are not available in Oracle Recievables view. So I was trying to create my own View.
I created a View in database. Now I am trying to create a Data source and associate this (custom created) View to it. However my View is not showing in the Views List of Values.
I am not sure whether I am doing it right. Can you please help me with this. Any pointers to a document which explains my requirement would be great.
Thanks
Sumit

Hi,
I have the same problem but, how can i know what my SID is ? i am trying with "ORCL" and it doesnt work.
Do you know in which file i can get it ? in the documentation of the installation i found this:
"If you are not sure of the values to enter for the URL, then you can query the data dictionary to obtain these values.
Connect as SYSTEM and run the following queries.
To retrieve the SID, execute: select instance_name from v$instance;
If you need to retrieve the port number, check the listener.ora file on the
back-end database."
But how can i query the database if i have not finished to install it yet and where is located the listener.ora file ?
I hope you can help me.
Thank you.

XML and Oracle 8i Lite

Hi Wizards
I'm in an endeavour to do the following things -
1.Generate XML output from Oracle 8i Lite database
2.Modify the XML and update the database taking the modified XML.
My java platform is JDK 1.2. I've used the XML SQL Utility for Java, and in doing so i've been successful with the 1st step. I've used the Oracle 8.1.6SDK JDBC Driver which is compatible with JDK 2.The code fragment is like the following -
import java.io.*;
import java.sql.*;
import java.math.*;
import oracle.xml.sql.query.*;
import oracle.jdbc.*;
import oracle.jdbc.driver.*;
public class orasql1
public static void main(String args[]) throws SQLException
Connection conn = null;
String tabName = "emp";
try {
Class.forName("oracle.lite.poljdbc.POLJDBCDriver");
conn = DriverManager.getConnection("jdbc:Polite:POlite", "SYSTEM", "manager");
catch (Exception e) {
System.out.println("Oracle Connection error\t:");
System.out.println(e);
System.exit(0);
OracleXMLQuery qry = new OracleXMLQuery(conn, "select * from " + tabName);
qry.setRowsetTag("SCHEMADOC_1");
qry.setRowTag("EMPLOYEE");
qry.setStyleSheet("emp.xsl");
String xmlString = qry.getXMLString(true);
conn.close();
try {
File output = new File("emp.xml");
FileWriter xmlFile = new FileWriter(output);
xmlFile.write(xmlString,0,xmlString.length());
xmlFile.close();
catch (Exception e) {
System.out.println("Output file error\t:");
System.out.println(e);
System.exit(0);
I am putting some sample code for step 2 in the following section -
import oracle.xml.sql.dml.*;
import java.sql.*;
import oracle.jdbc.driver.*;
import oracle.jdbc.*;
import java.net.*;
public class orasql2
public static void main(String args[]) throws SQLException
Connection conn = null;
String tabName = "emp";
String fileName = "emp.xml";
try {
Class.forName("oracle.lite.poljdbc.POLJDBCDriver");
conn = DriverManager.getConnection("jdbc:Polite:POlite", "SYSTEM", "manager");
catch (Exception e) {
System.out.println("An error has occurred.");
System.out.println("Please check your CLASSPATH variable..");
System.out.println(e);
System.exit(0);
OracleXMLSave save = new OracleXMLSave(conn, tabName);
URL url = save.createURL(fileName);
save.setRowTag("SCHEMADOC_1");
int rowCount = save.insertXML(url);
System.out.println("Successfully inserted "+rowCount+" rows into "+tabName);
conn.close();
Compiling the above code is fine, no errors! But while running the application I get the error -
Exception in thread "main" oracle.xml.sql.OracleXMLSQLException: java.lang.Class
CastException: oracle.lite.poljdbc.OracleStatement
at oracle.xml.sql.dml.OracleXMLSave.insertXML(OracleXMLSave.java:345)
at oracle.xml.sql.dml.OracleXMLSave.insertXML(OracleXMLSave.java:248)
at orasql2.main(orasql2.java:27)
My question is whether this thing can be done at all using Oracle 8i Lite? If so then how?
Waiting for ur advices.

It looks like be a classpath issue. Would you check with the class name.

Branch office installation of Oracle 8i Lite

I have developed a Java application using Oracle 8i Lite. I know, how to extract a required datbase file and supporitng run time files using deploy utility for stand alone machine. Thus, i can zip and send those file by email or thru web server to the client for installation on stand alone machine.
Since we can not use the Web to GO server, we want to send the Branch office database and its run time files (Only required files for running and not for developing) for server as well as for client to work in the LAN in the same manner as how deployed on stand alone machine without sending the Oracle lite CD and without using the Web to GO server.
In short, we want to install the Branch office Database machine files and Branch office client files by sending only required files in email without using web to go server and without sending Oracle lite CD.
Advance thanks for your valuable reply.
Thansk and Best regards

It would help if you told us the exact problem description and ... post in the correct forum. This forum is dedicated to oracle on apple's macosX.
What is the problem ?

Performance Issues on Oracle Database Lite 10.3.0.3

Hello,
we have a big problem with one of our customers. He uses Oracle Database Lite in the standalone version. There are about 600 clients running a project with about 20 Publication Items. The customer works in the logistics field, so the Main time where nearly all clients want to sync and get their tours is from 02 AM to 05 AM, so that is the time with the most traffic.
Everything went well before last week. Suddenly the compose cycle needs (at least between that hours) about ten times longer than before. Normally we had about 40 - 80 seconds, now we have about 300 - 500 average with max values from over 1200 seconds.
Therefore we have a lot of conflicts and Disconnects on the clients. It is sometimes that bad, that nearly no client can sync successfully.
We checked our Selects in the publication Items, all are very fast and look good in the explain plan, so that shouldnt be the problem.
The installation is nearly in the Default state as oracle does when you install Oracle Lite. Are there any standard settings we can change? Does anyone had the same problem already?
The Machine is a Windows Server 2003 with an Intel Xeon CPU E7-4820 and 4 GB of RAM.
Of course our customer gets a lot of trouble because of that and we have to improve and fix that as fast as we can.
Any recommendation or opinions are very welcome.
If I have to give more Info about somewhat please feel free to ask, I will give it as fast as possible.
Thanks in advance
Holger

Hey,
many thanks for your proposals. The MGP runs every minute like the default settings are, because our application is a time sensitive. The data have to be very fast on the clients in the nights and thex are only a few minutes before available. I think the parameters are important in environemnts where the mgps runs only after a few minutes?
Let me summarize the situation since my las post:
We have days (nights) where everything goes quite well. Mainly that is thrusday and friday. But on the other hand, there are days where everything really is a mess.
The mgp caycles increase and when you look to mobile manager you see 70 clients syncing very very slowly (about 300 - 600 seconds) for just a little bit of data. Then we get the disonnects and the messages in the err.log.
What do you think, is this somehow network related, or ist this a logical problem in the Mobile Server itself?
Like postes earlier, there are 500 clients syncing against a standalone mobile server.
We just couldnt figure out, why the mgp times somehow and sometimes increase that much, that there are these problems.
First we thought, that they sync newly over wireless (GPRS or Edge) and that syncing is that slowly, that everything goes down, but arent sure. Is this possible because of the architecture of the Mobile Server? That a very slow network can slow down the mgps and that does timeouts and all the other stuff?
How many clients can a Standalone Mobile Server normally serve at same time without performance problems. What do you thin about the hardware I wrote? Is it powerful enough?

PL/SQL and Forms executable in Oracle 8i Lite ?

I've got 2 basic and important questions:
1.) Is it possible to store procedures with PL/SQL in a Oracle 8i Lite Database(Operating System Windows 2000)
2.) Are the normal Forms 6i - Applications executable on a Oracle 8i Lite Database.
(Operating System Windows 2000)

Regardless of which path you want to take, in order to get the OCP certification in either the DBA or PL/SQL developer track, you must first obtain the respective OCA certification for that track. I'm assuming that since you are still undecided in which path to take that you haven't started working on either yet. If you look at the pages for the OCA DBA and OCA PL/SQL Developer certs and what is required for each, you'll see that the first block of tests for either certification (the SQL based exams) has the same options (1Z0-007, 1Z0-047, 1Z0-051) and passing one of those SQL based exams gives credit towards obtaining both OCA certifications. That might be a good place to start.
Doing one of these tests first might give you some extra time to decide which track you want to pursue. But as Justin said, it really depends on what you do (or plan on doing) in your career as to which path might be more beneficial for you.
As for the OCM level stuff, I wouldn't even think about it until you get the OCP. One step at a time... Same with OCP before OCA. That being said, my suggestions are just that, suggestions. You're free to take any exams/courses in any order, but you won't be able to obtain the certs until you have completed the requirements for each.

Sequencing and Trigger on Oracle 9i lite database

We created a schema (TESTSCHEMA) on Oracle 8.1.7 Enterprise edition and have a created a trigger which will use the sequence object to generate primary key for the table (TEST_TABLE)
Sequence creation:
CREATE SEQUENCE TESTSCHEMA.TEST_TABLE_SEQUENCE START WITH 6000 INCREMENT BY 1 MINVALUE 6000 MAXVALUE 6999 NOCACHE NOCYCLE NOORDER ;
Trigger creation:
CREATE OR REPLACE TRIGGER TEST_TABLE INSERT BEFORE INSERT ON TEST_TABLE FOR EACH ROW
DECLARE
pkValue NUMBER;
BEGIN
pkValue := 0;
Select TEST_TABLE_SEQUENCE.NextVal into pkValue from dual;
:NEW.TEST_KEY := pkValue;
END TEST_TABLE_INSERT;
We have created a snapshot of the schema on mobile server, synchronized the data with the client (Win32 for testing purpose).
The trigger works fine on the server, but when I run the same query on the lite database with msql it gives me an error:
[POL-3221] null key in primary index
I was wondering if Sequence generation and Triggers are supported on Oracle 9i lite database ? Or am I missing out something ??
Any information/ help is appreaciated
Thanks
Neeraj

You can't use SAVEPOINT / ROLLBACK TO SAVEPOINT statements in the database trigger:
ORA-04092: cannot SET SAVEPOINT in a trigger
ORA-04092: cannot ROLLBACK in a trigger
I am not sure what you need exactly, but you can try this:
