WLST Script for RDBMS Event Generator

Hello WLI Gurus,
I need the WLST Script for RDBMS Event Generator. There was a script in dev2dev but is no longer accessible. I need it for WLI 9.2.
Thanks in advance.

If you are using a cluster you need to make sure the connection pool and data source are deployed on the admin server. I have had this problem many times before.

How to create an RDBMS event generator using wlst on weblogic 10.3

how to create an RDBMS event generator using wlst on weblogic 10.3, i got a code fragment needing class "com.bea.wli.management.configuration.RDBMSEventGenChannelConfiguration"

Hi,
RDBMS Event Generator Channel Rule Definition
When you are creating channel rule definitions in the WebLogic Integration Administration Console, it is recommended that you do not use the Back button if you want to resubmit the details on a page.
You should always use the navigation links provided and create a new channel rule definition.

http://download.oracle.com/docs/cd/E13214_01/wli/docs81/relnotes/relnotesLimit.html
http://otndnld.oracle.co.jp/document/products/owli/docs10gr3/pdf/deploy.pdf
This problem has been seen in the past when defining the channel rule for an RDBMS Event Generator if schema name was specified with the incorrect case (i.e. lowercase when it should have been uppercase or vice versa). To that end, it is suggested to change the case of the schema when creating the channel rule

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
cheers

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 !!

Does anybody have a WLST script for step-by-step "smart" cluster restart?

Dear SAM,
are you looking for exchange 2013 installation. Please follow below link. I have done the same scenario as yours
1. install first VM - 2012
2. Static IP / loopback as primary DNS
3. install ADDS /DNS (forwarder to ISP)
4. install second VM - Static IP again
5. DNS of second VM to be the IP of first VM
6. this will join the domain
7. installation of exchange will be simple, configuration from this link : http://www.techieshelp.com/exchange-2013-step-by-step-configuration/
MARK AS USEFUL/ANSWER IF IT DID
Thanks

WLST Script for Disabling/Enabling Global SLA Alerting.

Hello,
I wanna find a way from the WLST to disable and enable the SLA Alerting which is under Operations-->Global Settings in the sbconsole. This is the global setting not per sercive!
I have found how to create a session and how to disable the alerts per service, but i cannot find which MBean is accessed when throught the sbconsole the global SLA alerting is disabled/enabled.
Can anybody point me to the right direction or help me to find how to do this from WLST.
Thanks.

Hi Ganesh,
I have finally created the script i was looking for.. I copy-paste it below as a sample... For sure you need all the lines of code until the comment i have put "#####you need this code above"
now the code you see below the comment is for disabling the global sla alerting... you have to write a bit to target a specific service that you want to disable.
Keep in mind that after you make your change you hava to include those lines in order to activate the changes and disconnect and exit..
sessionMBean.activateSession(sessionName, "enable SLA")
disconnect()
exit()
If you have access to oracle support search for wlst script for osb it has a lot and you can find how to target a specific service...
I hope that i help a little bit

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...

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.

WLST script for changing password for userid in Weblogic 9.2

Hello Everyone,
We want to change password for userid in weblogic 9.2. Is there a way we can do this by using WLST script? If so please provide me with steps for doing that using WLST. Thanks in advance.

Did you try going to the WLST documentation and searching for it? Go to [http://edocs.bea.com/wls/docs92/pdf/config_scripting.pdf] and search for "Changing a Password". The example there seems to be what you need.

WLST Script for Increase Log Level

Hi All,
How do we increase the log level of the log files using WLST ?
I know, how to increase the log levels using the EM Console page, but I want to know, if it can be done using WLST or Python script.
Thanks.

Here is a WLST script that you can adjust to meet your requirements.
connect('weblogic', 'welcome1', 'localhost:7001')
edit()
startEdit()
cd('/Servers/AdminServer/Log/AdminServer')
cmo.setLoggerSeverity('Info')
activate()
Run with $ java weblogic.WLST ScriptBoot.py
Note my server is called AdminServer, so you will need to adjust for your server name and change logging level as desired.
