RDBMS Event Generator

The RDBMS EG (from sp4 - it replaces the RDBMS adapter)produces an error when creating the channel rule definition:
'java.lang.illegalArgumentException: illegal group reference at java.util.regex.Matcher.appendReplacement...'
...when generating event triggers on (oracle) tables with colum-names containing '$' (which is end-of-line in java!!)
Is there any workaround (other than change the colum-names, which is not an option here since all DB names are auto-created by another apps.)?
Thanks
TH

Is it my question not clear? can someone let me know what am missing. I'm struggling get this working..

I have tried several things and had my team do research but we have not been able to find an answer to the problem.
If anyone can offer any insight as to why we might be getting this error it would be greatly appreciated. Thanks!

i also have same error during load testing, mainly this error
"Unexpected exception while enlisting XAConnection java.sql.SQLException"
i tried rerunning after increasing connection pool sizes, transaction timeout, but no luck, marginal improvement in performance though
also tried changing the default tracking levl to none, but no luck.
i am with 8.1SP5, how about you ?
do share if you are able to bypass these errors

RDBMS event generator & JNDI datasources

Hi everyone,
My WLI 8.1 SP5 is going nuts ! I'm under a cluster architecture, WL 8.1 SP6 with Red Hat Linux, JRockit 1.4.2_10. Deploying an application i need to create some RDBMS event generator, but when i do this, i get an NameNotFoundException looking for my jndi datasource ( see below ). The datasource is created and i can work with it, since it's a must for my application. How is it possible that a datasource exists for a web application and does not for an integration event ? Does anyone have any experience about this ? Any help will be very appreciated !!

Defining Channel Rules for a RDBMS Event Generator

Hi
I am trying to build my first RDBMS event (http://e-docs.bea.com/wli/docs81/manage/evntgen.html#1123751)
But I can only find the other types of events in the console
(File, Email, JMS, Times, MQ Series and HTTP).
What am I doing wrong? I have been reading through the help for the wliconsole too, and it doesn't say anything at all about RDBMS
Jon

In sp3, there is "Application Integration Design Console" avaliable at:
http://localhost:7001/wlai
and you can use this utility to define event generator for DB, but the utility at sp4 is better...

WLI 8.1 RDBMS Event Generator Problem

Hi,
I am using WLI 8.1 SP4. I have created a Trigger type RDBMSEventGenerator which publishes events in xml format.
It is supposed to poll every 8 seconds.
This event generator works fine if it is created after the server is started.
However, if the server is restarted, the same event generator stops polling completely. No events are published irrespective of the number of inserts made in the specified table.
Could anyone shed some light on why this is happening. I have tried to suspend and resume the event generator several times as well, to no effect.

I would ask in the WebLogic Server - JMS forum.

The funny thing is that in my one server development / test production environment I don't have any problems at the time of the RDBMS Event generators...
Please anyone can help me? Any special JMS queue need to be created or something?? I'm becoming desperate!!
Thank you all!
Oscar

Well
At last I've found the answer...
In order to successfully create an RDBMS Event Generator, the creation app (in this case, wliconsole) must have access to the destination datasource. Thus, both connection pool and datasource targeted by the RDBMS EG must be deployed in the same server running the wliconsole.
In this particular case, I just had to redeploy my datasources targetting all servers in the cluster plus the admin server and that's it...
See you...

in the weblogic console, i find the corresponding event generator application is abnormal, in the releated thread pool , available ejb instance size is 0, is it a problem?
in this situation, what can i do is just to delete the specified RDBMS event generator and rereated it , who can help me? i expect your suggestion and troubleshooting, thanks.

JMX API to Create Event Generator

Is there any JMX API available to create JMS event generator?
Thanks

Hi,
As mentioned in the last post go to the event screen by
Environment --> Modifications --> Events.
There you click on new entries and try writing your logic for event 21 i.e. after selecting 21 give some name of your event and write down the logic how you want to do this.
If event number 21 does not work then try 1. One of these two should work.
Hope this helps!!!

Lalit

Is there a replacement in Soa Suite 11g for RDBMS Events?

I'm looking for the best way to integrate a database with OSB resources. What I need is that for each new record into one table in a Database, triggering an execution of an OSB service, but I have the ability to use any component of the SOA Suite provided they can finally claim a OSB Proxy Service.
I have experience resolving a similiar scenario with Weblogic 8.1 using RDBMS Events, but that they were deprecated, is there a similar component? I was searching on EDN but did not find the possibility to connect to a DB
Thank you very much for your time

May be you are looking on polling ability of DB Adapter which is definitely an option but I always suggest to use Oracle GoldenGate for such use cases.

Hi Scott,
I need a transaction from the MDB since I am not using an EJb to pursue the action.
Hence I need to retain the <trans-attribute>Required</trans-attribute> at the
MDB.
Have any answers?

It's resolved.
The MDB automatically created by JMS Event Generator defaults to be deployed
with
“transacted”. That requires the foreign JMS provider to be “XA”.
The deployment descriptor is created as <domain-directory>/WLIJmsEG_<event_gen_name>.jar
e.g. C:\bea812\user_projects\domains\jmsInterop\WLIJmsEG_mqQueueEventGen.jar
Since MQ in the localhost and remote SLUDV18 are not XA-enabled, we had
to manually
change the <container-transaction> section in ejb-jar.xml:
From :
<trans-attribute>Required</trans-attribute>
To:
<trans-attribute>NotSupported</trans-attribute>

How to determine the event generating component in RESTORE-VIEW phase

Hi,
I have performance issues with my application.
I am using PPR for components within the CoreTable. The table-model for this ADF-CoreTable is coded in java instead of binding it to PageDef table.
The PageDef for the JSF page is heavily loaded with other objects & therefore there a delay in response. I have also found out that maximum time is lost after the RESTORE_VIEW process to before APPLY_REQUEST_ VALUE phase.
Not sure if I am doing it right, but this is what I plan to do.
On determining the event from CoreTable components, I want to bypass the ADF phase by passing null to all ADF Phases
initContext(null)
prepareModel(null)
& before Invoke application
prepareRender(null)
Is there a way to determine the event generating component in the PhaseListener class?
This is a ADF 10g project developed on JDeveloper 10.1.3
Thank you,

Just for other readers,
I attempted to create a button to toggle a session scope Flag for test & proceed. However I was still unable to skip the ADF phase.
In a self defined PhaseListener I also tried to remove ADFPhaseListeners before RESTORE_VIEW & reinstate it back in before RENDER_RESPONSE. Except the ADF InitContext() & processValidation() which run immidately after RESTORE_VIEW all other calls to ADF Phases were skipped.
The reasults were not helpful to proceed as I need to entirely skip/bypass the ADF lifecycle to achieve the quick responce.
Thank you
