Oracle 10g Lite and sequence

Hello,
I'm developing a VB.net application that will run on 20 CE.net devices. I'll be generating a bunch of different recs on these CEs.
I have a guestion on how an Oracle sequence is synchronized by mSync when there are multiple clients. I can't test since I only have 1 device right now.
Say a sequence S1 is used on all devices and device D1 used S1 until the nextval is 100, then anothe device D2 used S2 until the nextval is 200.
D2 is then docked and synchronized. D1 is then docked and synchronized. What is the nextval of S1 on D1?
I want to use this sequence to create a unique key for each CE device.
Thanks.

Delphi 7 connects to Oracle Lite through the standard Microsoft OLEDB to ODBC driver. I've used it in testing and not had any problems with it.
You have to have Delphi 7 Pro, Ent, or Arch to get the ADO tab of controls.

Oracle 10g lite and Oracle 8i compatibility

I have a series of Oracle 8.1.7.4 database servers running on Unix platforms scattered around the globe that use multi-master replication for synchronization. I need to populate approximately 500 Windows 2000 deployable systems that will operate in austere communication environments. These remote systems will need to be kept synchronized with the primary servers. I have no choice but to keep Oracle 8.i on the primary servers but have some flexibility in deploying a more current version on the PCs. Are there interoperability problems between Oracle 8.i and 10g Oracle Database Lite?

After having wasted 2 days trying to get Oracle Lite 10g Release 2 (10.0.1.2)working with Oracle RDBMS 1.8.7.4 (running on VMS) we failed. We had to downgrade to OLITE 10g R1 (10.0.0.) that evntually worked in combination with 8.1.7.4. We also found out that Oracle Lite Mobile Server repository should reside on the same Oracle instance as the back-end 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 10g Lite Review

Hello,
It seems there are a lot of folks out there who have successfully implemented Oracle Lite solutions for their remote users and leverage database snapshot replications.
Can anyone please share their input about this product from implementation/ deployment and maintainence perspective?
We are in the midst of product evaluation but are unable to estimate how much (if applicable) difficult it is to develop a system using Oracle lite 10g.
Oracle 10g Lite has no patches available yet. Do you think it has significant bugs to hinder development efforts significantly?
If you could let me know if this product has significant issues implementing or maintaining, it would be great.
Thanks much for any input on the matter,
Milind Shah

Hi Milind/Payal
I have currently implemented a web application(struts) on Oracle Lite Webtogo and is now running in production. Currently around 30 users are working on this. Some 100 more users would be added in mid June, 2005 and another 150 users in mid Sep, 2005.
The application size is also very big around 20MB of jar file size. So you can imagine how big the application it is. Also one more good point is that we have also implemented XML FOP for generating PDF reports at runtime which are also huge reports. We also have tables with BLOB column to store documents as documents cannot be accessed directly from file path.
Yes I had some problems in between but I could resolve it by my own.
There are some more problems that we are facing nowadays but are not very critical but though critical for the user point of view.
1. A critical issue of changing sequences window/thresold size after publishing it for the first time. Resolved after writing a consolidator program to change the same into the mobile server repository.
2. Some users are facing performance issue i.e. The application is taking around 3-5mins to open up after clicking on the link in the client workspace. We have identified that it is not the problem with Oracle Lite but with Tablet PCs the users have been given to work on. There is no problem in desktop or laptop and not even in most of the Tablet PCs. But I am still working on this issue to resolve.
3. There are 2-3 users who are getting java.lang.Exception error message on clicking of the application link on the client workspace. We are still working on this issue to resolve it. Still don't know what can be the possible reason.
I hope this answers your queries. If you have more queries do feel free to let me know at [email protected]

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...

Oracle forms & reports support on oracle 10g lite

Currently our oracle forms & reports 6i application works on oracle 8i database with oracle 9i lite.
We upgraded our database to oracle 9i r2 and lite to 10gr2.
After publishing the application when i try to open the application the forms screen disappears for ever.
I wanted to know whether oracle forms and reports 6i is supported on
oracle 10g lite r2?
Thanks,
Ashok Kumar.G

No. Not only it isn't certified, but it is also impossible to run forms compiled with the 11g compiler with the 10g runtime. For 11g there is a install bundle for the developer suite / application server.
cheers

Oracle 10g Lite-Sync Error

Hi,
I am Using Oracle 10g"Lite" Database, I am doing manual SYNC Process.
Today I started the manual Sync Process i Got this Error Message in the Screen "POL-3201 Invalid Slot Number"
I referred a document Shows this information
POL-3201 Invalid slot number
Cause: Internal error caused by referencing an object that has been deleted. Each
object in the database, such as a row has a unique object identifier (OID) that
identifies the location of the object in secondary storage. Each database file is
divided into fixed size chunks called disk pages. An OID can become invalid
when the:
■ disk page being referred by the OID does not exist in the database file.
■ physical read or write of the disk page fails due to an operating system related
error.
■ address of the object (as indicated by the internal encoding in the OID) in the
disk page is outside the page.
■ object is not found in the page.
But i did not delete any thing in the Lite database.
Yesterday the Manual SYNC was Successful ...After i did not touch the Lite Database.Today I started the SYNC and i Got the Error.
Did any one face this error?
Please advice on this Error
Thank U for the Useful Information
SHAN

See if following OTN forum thread helps...

Oracle 10g Lite Database User Creation

Hi,
I am using Oracle 10g Lite Database Release 3, I Like to Know How to Create a user in Oracle 10g Lite Database through Command ,Any Advice
Thanks U

Shan,
In the same way you create user in any other oracle database. I recommned to check following Oracle Lite Sql reference document for creating user from command line.
http://download.oracle.com/docs/cd/B19188_01/doc/B15917/sqcmd.htm#sthref487
or
sql> CREATE USER liteuser IDENTIFIED BY "litepassword"; -- And add required privs to the user.

Documentation for Oracle 10g Lite

Hello
I have docummnetation for oracle 10g Lite but there is only informations what to do step by step. I'm looking generally informations about the features mobile databases, synchronization system, managment, and all development support. Where can I find them??

I run Oracle Lite on Pocket PC, and I make some simple program which did some operations on database. I know that the support for .NET is small. But I'm writing the master of science work about three mobile databases (sql ce, oracle lite and sybase) and I have to write a program which will be testing performance of those databases on the mobile device.
Generally I hope this program will work ok. But I also have to write about fuures for example oracle database lite RDBMS, but in documentation there is only few generally informations and almost all document is about how to configure it and how to do something.
So if you have some generally documents (I have those white papers and other pfd on oracle site) please send it to me [email protected] .

Oracle 10g XE and Oracle 8.1

HI,
I am new in oracle and I installed both Oracle 10g XE and after Oracle 8.17 Standard with Apache server. Does anybody know why Oracle 10g XE doesn't start (doesn't find APEX) when Oracle 8.17 is running on the same computer?
Tks,

You can not use XE parallel with another Oracle instance. Only one instance per network.

Error to connect oracle 10g client and designer BO 4.0

hello,
I try to connect oracle 10g client and designer BO 4.0.
I created an ODBC connection to function in the administration tools of data sources but I can not connect once in designer.
I tried using the driver directly oracle designer 10 but I have the same error that is this:
DBD: ORA-12154: TNS: connection identifier specified could not be resolved
someone there had the same concerns?
cordially

Hi,
so it looks like that your TNSNAMES.ORA file isn`t properly configured. Thats why you can connect with the IDT to your Oracle Database.
Your DBA`s should sent you the correct TNSNAMES.ORA file or the entry for your DB prior. After the tnsping works, you will be able to use the IDT properly.
