Yes as Daniel mentioned you can access the objects in a remote database using a database link. Select * from [EMAIL PROTECTED] kind of thing.

Re: [OT] Java as a Daemon
Hi, Just adding my 2 cents. Go with Duncan because: 1) He works for Oracle, so he _must_ know what he's saying :) 2) His approach works nice here in my job. Oracle's replication features work good. If you are a bad luck guy that doesn't have a DBA in your team (yeah, it is possible) you can try using a db link so your code doesn't need to make two database connections. Let Oracle handle the connection to the other database :) HTH, Daniel Silva. On 7/14/05, David Whipple <[EMAIL PROTECTED]> wrote: > We use the cron approach as well.

We use the cron approach as well.

Re: [OT] Java as a Daemon
I'm with Larry. Cron rocks. The only problem you should have in mind: if your job needs more then the time between the jobs, you've lost. We had actually this problem, and it killed the db, because (2 years after initially written) the script lasted more then 24 hours, and after a week 5 instances of it runned, blocking each other and producing a load of 10 on the machine. So simply add a check "am I already running" to your code, and it will be fine :-) regards Leon On Wed, 2005-07-13 at 21:49 -0600, Larry Meadors wrote: > I would probably go the route of the .sh file. > > At the risk of starting a big flame war, cron is solid as a rock, and > all of the memory used by your app will be freed up when the JVM > exits.

I would probably go the route of the .sh file. At the risk of starting a big flame war, cron is solid as a rock, and all of the memory used by your app will be freed up when the JVM exits. Why make it more complex by adding quartz or tomcat to the mix if you do not have to. Simple is *almost* always better.

RE: [OT] Java as a Daemon
Richard, Can you run it in your webapp container? You could then update an object in application scope with the id's of what records have changed. You could even change your DAO to perform that step for you. Then you could have the quartz scheduler running to periodically update things without needing to run any additional code, crontab, atq, etc. All of this from inside your Struts webapp. FYI, Quartz is at http://www.opensymphony.com/quartz and no, I have no affiliation with them. LOL. Regards, David -Original Message- From: Richard Reyes Subject: [OT] Java as a Daemon Hello Guys, I need your suggestions. I have a task to create an application to sync records between 2 Oracle 10g database. Not the whole records of the database though, just the now and then transactional updates. Access to the db's would be both via web services. I think I have an option to do this like - a simple java application executed via .sh file - a java application running as a daemon on a unix box But I really am not sure which better path I should take. Any suggestions would be very much appreciated. Thanks Richard - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
[OT] Java as a Daemon
Hello Guys, I need your suggestions. I have a task to create an application to sync records between 2 Oracle 10g database. Not the whole records of the database though, just the now and then transactional updates. Access to the db's would be both via web services. I think I have an option to do this like - a simple java application executed via .sh file - a java application running as a daemon on a unix box But I really am not sure which better path I should take. Any suggestions would be very much appreciated. Thanks Richard - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
