Problems creating RDBMS Event Generators in a WebLogic cluster

Hi Everybody,
I just set up an integration cluster with one admin server and two managed servers into only one computer.
My deployed Application needs an RDBMS Event generator with 5 channel rules to be created and when I create the first channel rule I get this exception:
java.lang.NullPointerException

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...

Problem creating iCal Events from Mail in Leopard

The new function that allows the user to create iCal events from Mail messages is quite impressive and very useful. Unfortunately the data detectors seem to have trouble with certain commonplace date formats. While the detector recognises the date, it cannot activate an event in iCal. For instance the data detector will pick up the dates in these formats and create iCal events:
30 October 2007
30 Oct 07
30/10/07
but not in this format:
30-Oct-07
In the latter case, the data detector recognises it is a date, produces the drop menu, but will not carry through and create an event to iCal. It's annoying in that many companies use the latter format in their communications. Any workaround?

There is another problem I have found.
I have my computer set in international settings formats to show the date in the "English format"
January 4th 2007 is 4/1, however an entry in mail 4/1 is put into iCal on the first of April!
I found this out after looking for a meeting I knew I had put in for next week.
beware, can this bug be fixed?

HT2513 Problem Creating Recurring Events in iCal.

Hello.
I'm having some issues creating a recurring event in one of my iCoud Calendars on iCal.
If I create a new event then go in and change the recurrance, time, and name it stays in my iCal for a few seconds then defaults back to a basic appointment with no name, time, or recurence. I then need to go back into the event and reprogram everything. It will then save the changes.
Its a little annoying as I need to reprogram the even and save it twice.
Has anyone had this problems, and could offer assistance?
Thank You!

The same thing happened to me! I'm in another discussion thread about this and it seems many people have the same problem and it all started about a week ago

Is there a way to create Event Generators in WLST?

In the PO sample there is code to create JMS Event Generators using Jython. Is there a WLST equivalent?
I tried using the JMSEventGeneratorsMBean (from com.wli.management.configuration) but got errors about the number of arguments.

Hello Karel,
The PO Sample does indeed use WLST, but as a Module in jython.
thanks,

Generally we get this error when we did not packaged properly, like if use
tool win zip for packaging the bean.
1. when you are building EJB jar, please make sure that you have created a
directory "META-INF" with upper case letters
2. Make sure that you have deployment descriptors in 'META-INF".
3. Use Command line console, java command to package the bean like
"jar -cv0f".
ignore this mail, if you already done this way.
Can you try packaging your

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"
but i can' t find this class in classpath on weblogic 10.3, pls help me, thanks. code sample is better.

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/docs85/deploy/cluster.html
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

Kal

Problem creating user in RDBMS realm Using com.bea.wlpi.rdbmsrealm.RDBMSRealm

Hi,
I am currently using WLI 2.0 SP2 installation. Here is a very unusual thing I
noticed. Can somebody tell me what is going on ???
1 : I have set up the security realm as indicated in the config.xml file. As far
as I understand, the caching realm entry has attribute pointing to the wlpiRDBMSRealm,
which is a RDBMS implementation from the WLI 2.0 SP2 distribution.
2: I start the server, open the WLS console, and create a new user through the
console. I get no error message and it seems to work fine. ( I also click on the
save it to database link, and it returns with msg that cache is refreshed ).
3: I see an entry in the fileRealm.properties file, but no record is inserted
in the WLSUSER table in the database.
Since the RDBMS realm (from WLI distribution) is defined as basic
realm implementation, should it not insert entry into the database, instead of
the file realm.
Is this a general problem ( any RDBMS realm ) or is it specific to the WLI ?
Is there anything that I have not configured here that is causing this behavior
Is it just refreshing the cache instead of inserting record in DB ?
Why should it insert entry into fileRealm.properties ?
Thanks,
Girish
[noaa1.zip]

Hi,
I turned on the caching realm through the WLS Console, (Security).
After this I get a very unusual error, which seems to be comming
from the RDBMS implementation class (from WLI 2.0 SP2 distribution).
Here is the msg that I get while WLS server boots (the WLS server boots ok, but
WLPI does not initialize) ....

Hi,
I am currently using WLI 2.0 SP2 installation. Here is a very unusual
thing I
noticed. Can somebody tell me what is going on ???
1 : I have set up the security realm as indicated in the config.xml file.
As far
as I understand, the caching realm entry has attribute pointing to the
wlpiRDBMSRealm,
which is a RDBMS implementation from the WLI 2.0 SP2 distribution.
2: I start the server, open the WLS console, and create a new user through
the
console. I get no error message and it seems to work fine. ( I also click
on the
save it to database link, and it returns with msg that cache is refreshed
3: I see an entry in the fileRealm.properties file, but no record is
inserted
in the WLSUSER table in the database.
Since the RDBMS realm (from WLI distribution) is defined as basic
realm implementation, should it not insert entry into the database, instead
of
the file realm.
Is this a general problem ( any RDBMS realm ) or is it specific to the
WLI ?
Is there anything that I have not configured here that is causing this
behavior
Is it just refreshing the cache instead of inserting record in DB ?
Why should it insert entry into fileRealm.properties ?
Thanks,
Girish

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.

ICal problem creating event in month view

iCal does not allow me to create an event when in Month View. I used to be able to double click a date in Month View and could easily create an event. It does allow in Week View, but I like to use Month View. Anyone have this problem> Solution? Thanks!

I just barely had this problem. I restarted the program and it worked.

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 !!

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

Using NFS Auto Mounts with File Event Generators (FEG)

Has anyone had experience with using WLI file event generators with auto mounted NFS filesystems? The problem that we are running into is that threads are staying blocked if there is an I/O request to a hard mounted NFS filesystem that does not return a response. We know we need to figure out why periodically we are not getting a response from the NFS server on some requests, but the thought is that at least with auto mounting, the request would time out and the thread would continue, process the I/O exception, and then go back into the pool. Thx.

OK, I have a work around that will do for now: disable DNFS, like this:
cd $GI_HOME/rdbms/lib
make -f ins_rdbms.mk dnfs_off
Re-start ASM, and then it works:
SQL>
SQL> alter system set asm_diskstring='/dev/sd*1','/u01/nfs_shares/asm/*' scope=memory;
System altered.
SQL> select group_number,path,header_status from v$asm_disk;

But clearly, this is not ideal. If anyone has any other suggestions, I would be very grateful.

Cannot create new Events in specific Dates???

I am having a problem creating a new event for a specific date, November 4th. What I did: I duplicated an event that took place in October 30th and dragged it to the desired date, in Monthly View, but iCal doesn't let me drop it in the day I want. The event can be dropped in the previous (3rd) or the next day (5th).
When I use Daily View, i can navigate up to November 3rd, but then the left-arrow button does not take me to 4th.
Has this happened to anyone? Can anybody help me?
(by the way, I am using iCal 2.0.5).

Hmm....I was able to fix my issues. I'll share it here in the event it can help you.
While iCal was closed I simply moved to trash the folder "/Users/<my username>/Library/Application Support/iCAl/" I then re-opened iCal and I could then create new or import old ".ics" files, close iCal and re-open with all information being retained. Sweet!

I cant create new events in iCal on my Mac or display them

Since a few days ago after upgrading to Lion when I want to create a new event it
dosent show up in my calender. All the old events is shown and when I create an
event for example on my iPhone and sync with iCal on my Mac I can see the
new event.
I click in the calender to make a new event, nothing shows up, but when syncing
with my iPhone I can see the new event without any text because I didnt see the
small eventbar to type in or make the right time for the event. Can anybody help
me with this issue?
Regards,
Collins from Sweden!

Called Apple fast track support and problem is resolved. User error, for some reason I had selected the wrong calendar - after selecting the proper calendar on the left sidebar I could create events. Apparently at some time I created a 'todo' mailbox. It had nothing in it and I ended up deleting it so it doesn't get selected again in error.
Took 15 minutes to connect with an ICAL specialist. Once connected received excellent support.
