We plan to use server initiated sync using oracle lite in our current project. Can you explain how the server initiated sync works?
Does autosync agent makes a constant connection to server? How do we push server data changes to client in real time without client pull. What happens when the server tries to push data and there is no network available. What are the various protocols are used for the transport
Much appreciated your help in this regard.
We have little time left to decide between oracle and sybase solutions
thanks

Hi,
We have a Oracle Lite application that has resequenced the clients after a publication. I am wondering if there is a way of forcing a push of the server data to the clients whilst ignoring any transactions coming back from the client?
Any assistance would be greatly appreciated.

Hi Gregg,
I’m getting an error when trying to do an initial sync using the mSync API. The following is the error message:
javax.servlet.ServletException: An internal error has occurred. Server busy
Do you have any suggestions?
Thanks,
John

Hi Gregg,
Another question? Is there a Java API to log into the mobile client? I haven’t been able to find one.
Thanks,
John

Hi Fabricio,
Have you looked at the OLLOAD utility. It’s like sqlldr for oracle lite. I think that is what you are looking for right?

Hi Lijo,
What type of client are you working with? And is it the database client or the webtogo or OC4J container?
Thanks,
Greg

The file you want to modify is
$ORACLE_HOME/j2ee/mobileserver/applications/mobileserver/setup/common/webtogo/webtogo.ora
[WEBTOGO]
JAVA_OPTION=-Djava.compiler=NONE -Xms256M -Xmx256M
Do you have a webtogo application that you want to build with eclipse?
Do you really need to allocate that much memory to the client? Or is this for the branch office administrator user? Are you running out of memory?

Lijo, you can configure all those programs the way you would configure them for a deployment on any application server. I don’t have a step-by-step demo and I don’t know what architecture or framework you are using. The only part you need to be concerned about is the connection/connection pooling. You have to set up your datasource to use.
http://download.oracle.com/docs/cd/B19188_01/doc/B15920/nvappdev.htm#sthref706
There are better demos out there and when I find them, I will post them.
You can use whatever IDE you choose, the deployment however has to be geared for OC4J or Webtogo (very similar).

What version of the product are you using? And when you say “webtogo server”, are actually talking about the Mobile Server and not the software that is running on the client right?
So, answer the following:
What version of the product are you running?
What type of deployment are you implementing? (Win32, Webtogo, OC4J)
Are you running Oracle Application Server or Standalone more?

Hi Lijo,
I think in the newer releases, that RunWebServer.java doesn’t work. I think I had tried it once and there are some methods that are either deprecated or removed entirely from the webtogo.jar file.
So, I think your question is, “How do you get a webtogo application working with different application servers?”
In JDeveloper, for example, you import your WAR file and then you set up your connection to use the polite driver instead of the webtogo driver for your database connection. The webtogo driver only works in the context of the Webtogo/OC4J environment. This should be the same in any other application server you are configuring. You can configure it to work with an Oracle driver and an Oracle database, but there are some Oracle specific JDBC methods that webtogo doesn’t support. This is why I recommend the Polite driver over the other two.

There is examples with J2ME and Java, .Net, and I believe there is a ADF/BC4J example in there as well on the SDK.

The exemples use java inside oracle lite like store procedures and etc… but I don’t find an application exemple in java or j2me, like the transport application in vb.net for Pocket pc.

Here is a quick sample of how to use the two Oracle Lite JDBC drivers:
http://www.rekounas.org/2007/01/15/wtgjdbcdriver-vs-poljdbcdriver/
If you are doing straight Java, not J2EE, you use the POLITE driver. If you are doing J2EE with the Webtogo or OC4J containers, you use the Webtogo Driver.
Java programs in Oracle Lite work the same way as any other JDBC program. It’s just the driver that is different.

Hi!
If I choose the exit option, the install finish.
I need a little bit help! I’ve got a problem still installing the 11g Lite edition. In opposite with the install guide, I cannot add server options in the Reposiroty Wizard. But when I install the server and start the Wizard, it try to connect to the non-created database
After it I start the Mobile Server command line, I see, the next message: “Application: mobileserver does not exist. Error creating Web application: webtogo”. And the command line stopped.
I don’t know what should I do, because it is almost a next-next-finish install wizar…
Any idea?
Thx your help!
Bye and regards,
Attila

The repwizard builds the database repository and deploys an application called mobileserver… basically the middle tier. Without that, you can’t do database replication.
What exactly are you trying to accomplish? Do you just need the development kit, or do you need to install the server as well?

I would like to install a database server, where we can create databases. I downloaded this install kit from the Oracle web site, so I don’t know why is the difference between the installation and the install guide?
Is this install kit appropriate?
Thanks!

Mobile Server is a middle tier. You have to install a database first. If you need oracle lite to be your database, you install Embedded Oracle Lite. Or just install the Oracle Lite SDK.

Please explain the difference between “Oracle Lite Web” and “Oracle Lite Web OC4J” platforms.
We are working on the requirement for a Mobile Application, which is already deployed on JBoss but we will be putting another instance on OAS for mobile users. We will have the same database being accessed from JBoss and OAS.

Oracle Lite Web runs on a Servlet runner with limited technologies (Struts, Servlets, JSP, etc). Oracle Lite Web OC4J has all the capabilities of a J2EE application including JSF, EJB, ADF, etc.

So, when you do an initial sync, you do not have an issue, but when you do an incremental you do?
Set DEBUG=1 in SYNC section of the polite.ini before your next sync. There will be a debug#.txt generated from that sync. Examine the exception in the file to see what it is telling you.
