Dequeue Messages queued by caprture process

RDBMS Version: 10.1.0.4
Operating System and Version: WINDOWS 2003 SERVER
Error Number (if applicable):
Product (i.e. SQL*Loader, Import, etc.): Oracle Streams
Hi,
Can I do the following.
I had set up couple of databases for replication using ORACLE STREAMS in hub configuration(One central and many local). My problem is that sometimes some of the connection between them will not work for a significant period of time. That's why I need some tool to move the data.
So I decide to dequeue the which are captured by the CAPTURE process and to process them with a PL/SQL program, save their payload in a file or external table and then trough some way to bring this data to the master server and the other way round.
But I can't dequeue messages because the agent created for the propagation process has no name and I can't dequeue messages if I don't have the CONSUMER.
All examples that I saw in Metalink use already propagated messages with a propagation process.
So I need some other way to propagate my messages different then propagation process! The task is even more complicated because at the central DB some of the messages has a multiple consumers...
Any suggestions?

Wel in 10g it is just as simple as: create a apply-process by adding a table/schema rule that matches the enqueued messages. If you have a captureprocess for several tables off a schema, then a schema rule for that schema owning those tables would do. Then with the set_enqueue_destination api you can add a queue on this rule. Which means that the apply process won't apply those messages but reroutes them on your user-queue. This queue you can create by yourself but it must be of type 'sys.anydata'.
The messages enqueued on that queue by the apply process can be dequeued by a user process.
So just put-in an apply process that dequeues the captured LCR's for you and enqueues them on your user-queue. And then you can dequeue them.

Martien

How to dequeue messages that were enqueued when app was offline

I have 2 question. The following is the scenario -
I have 2 different process. Process A and Process B.
Process A enqueue's the message in the message queue.
Process B dequeue's the message from the message queue.
1) Process B shuts down for some time but Process A continues to enqueue the message in the queue. When Process B comes back live how to dequeue the messages in the message queue that were posted by Process A when Process B was offline?
2) The queue that I am using is multiple consumer queue as there needs to be more than 1 Process B to dequeue the message. The logic behind the design is if one of the process B dies the other process B can still continue to process. At the same time if 1 instance of Process B has picked up a message it should notify other Process B to not process the message.
I coudn't find any samples. Any help is greatly appreciated.

Hello,
The messages that process A enqueues and are not consumed while process B is down will remain in the queue until process B restarts.
It sounds as though you don't need to use a multi-consumer queue as all you appear to want to do is consume the messages as quickly as possible. Is that correct? If it is you could have multiple process Bs consuming messages from the same single consumer queue. Messages that one process is consuming will not be available to another and this is handled internally.
You can also have multiple processes consuming messages associated with the same consumer on a multi-cosnumer queue and the same applied.
Or you could have multiple processes on a multi-consumer queue associated with different subscribers which are all interested in the same message.
What you use depends on what your design requires but each message will be consumed only once in the case of a single consumer queue and only once per subscriber/recipient in a multi-consumer queue.
Thanks

Multiple Processes dequeuing messages from same queue

Hi,
I have 2 Processes that are listening on the same queue to dequeu the messages. How can i make sure each process picks the message intended for that process. What setting do I need so that each process picks the right message not all the messages.
As some messages needs to be processed by Process1 and some messages by Process2.
Thanks

I would like answer to this too! The only way I can solve this is by having 2 queues.
As far as I can figure out, the dequeue just picks up the next available message. Both processes can dequeue the same message if you make the queue multiple consumer.
The processes that picks up the message can put it back if the it is not meant for itself - but this is an inefficient and potentially ineffective solution.

Dequeued messages not deleted from one queue but other works

Hi,
I have a multiconsumer queue with two local subscribers.
The messages go to the 'PROCESSED' state but do not get
deleted from the queue table.
As a test, I created another single consumer queue in a different andqueue table, but the oracle deleted the 'PROCESSED' messages as expected.
In the multiconsumer queue, the messages are added by a trigger on the table. The enqueued messages varies from 100000 to 10000 per hour.
aq_tm_processes = 5
job_queue_processes=4
What else can I do debug the problem?
Is there any log file on the database server that I can
look at any potential problem.
I would appreicate any responses. This could very well
be a newbie problem. I have not worked on advanced queues
before and nor has anyone else in our system.
Thanx,
HB.

I forgot to add that I am using default retention time
and when I query user_queue the retention time is set to zero for the multiconsumer queue.

Dequeueing message from xmltype queue

I have the queue build upon the XMLType (too complex to use it as a payload). When I'm trying to dequeue messages with ESB AQ Adapter they are not passing through. When building the service adapter I've specified the same schema file as destination payload type so it's rather impossible to have any differences. Is it necessary to do anything special (transformations or so) to make it working ?

This is not a supported feature. The best solution is to write a java callout to pull the message from the queue.

I want to use ODI to read XML messages from JMS queue and then process it..

I want to use oracle ODI (Oracle Data Integrator) to read XML messages from JMS queue and then process it.. i also want to process and validate the data in it....
Could anyone please tell me the steps to achieve the same. I tried some ways which i got on OTN, but not able to implement it exactly...
As i m very new to ODI, it will be great if you provide detailed steps..
Thanks in advance for your help....

Hi,
Were you able to do it? We are facing this same issue now and, despite the fact the docs say otherwise, it does not seem to be a trivial task.

Dequeuing messages not working

I am trying to dequeue messages through the use of a java durable subscriber. That is the only subscriber. I successfully get the message and then call the method _session.commit();. Neither throw any errors and I am confused as to why the queue shows the message as processed yet it is still in the queue. Is there an orcale process that needs to be running to remove these dequeued messages? Propagation between databases is not a valid solution. So, some of the examples do not hold for my current setup.
my setup:
oracle 9i
create table, schema, objects, trigger to push jms messages into queue
java client to dequeue messages.
One strange thing I notice, at least to me, is that in order for the trigger to place messages into the queue, i need to either start the java durable subscriber up so it creates a subscriber or run the following: EXECUTE create_subs ( "name", "queue_name", null, null );. Now do I now have two subscribers once I start the java client up after running the PL/SQL command?
per my requirements I need to be able to queue things through a trigger, thus I need to be able to queue messages without having a java durable subscriber running.
Is there a way to determine who is subscribed? For some reason I am not seeing the information i need in any document or on any list.
Any help would be greatly appreciated.
Thanks,
James

createDurableSubscriber creates a new subscriber or gets an handle to an existing subscriber.
When you enqueue a message - you must either have created the subscriber or explicitly specified the recipient during the publish. From what you are seeing it seems that you are trying to enqueue a message without creating the subscriber.
If you want to do this then you must explicilty specify the recipient in the publish call. You'll need to use OJMS extensions in AQjmsSession to do this. The recipients can be specified as an array of AQjmsAgent s

Consuming queue from multiple processes

We have a program designed to consume a queue with consumer name set to "consumer". Here's how it dequeues messages:
dequeue_options.consumer_name := 'Consumer';
dequeue_options.navigation := DBMS_AQ.FIRST_MESSAGE;
dequeue_options.WAIT := 10;
DBMS_AQ.DEQUEUE(queue_name => 'ourschema.our_que',
dequeue_options => dequeue_options,
message_properties => message_properties,
payload => message,
msgid => message_handle);
If we run one instance of this program this dequeue operation above uses 10 CPU seconds over the duration of our load test. If we run two instances of the program (which consumes the same queue as the same consumer) then the dequeue operation above uses 160 CPU seconds. We need the second instance to remove a single point of failure but the 16 fold increase in load on our database is not acceptable for a dequeue operation.
Why is it so expensive to have two processes dequeuing from our_queue using the same consumer name?
thanks
Dale

We managed to solve the problem.
We had initiated a transaction to bracket the dequeue and a subsequent insert. Removing the transaction seems to have removed the performance hit from the second process.

Dequeueing messages in enqueue order

Is it possible to determine the order in which messages were enqueued when two or more processes are running concurrently and enqueueing messages to the same queue? In the FAQ section of the AQ documentation it states that if two or more messages are enqueued at the same time the STEP_NO column of the queue table can be used to determine the enqueue order. But apparently this only works when the messages are enqueued in the same queue session.
In my situtation I'm using Oracle8i Enterprise Edition Release 8.1.6.0.0 and I have two or more processes, each with its own queue session, enqueueing and dequeueing messages to the same queue. I have to be sure that the messages are dequeued in exactly the same order that they were enqueued. How do I determine the order that two messages with the same enqueue time were enqueued when each message was enqueued a in different queue session?
Thanks for your help.

Does listen get unblocked if there is uncommitted dequeued message

Here is the scenario.
I have 2 threads.
1 comes in; Does listen on a multi consumer queue. Gets a message and starts
processing.
At this point 2 comes in; Does the listen; At this point there are no new messages
on the queue. But thread 1 has not committed the dequeue. Will the listen wait
for the duration specified ? or will it return right away?
If it did return right away, then I cannot really do a listen until the thread 1 has committed.
What is expected behavior?
Thanks
Vijay

The answer to your question is I don't know because I would never enqueue or dequeue messages with default parameters. Not only is it a bad practice in that behavior can potentially change after upgrading or applying patches but doing so makes maintenance infinitely more difficult, as you are now discovering, because no one necessarily remembers for each version what the default behavior is.
When you want a specific behavior you code that specific behavior.
Read the docs on the following:
dbms_aq.dequeue_options_t
dbms_aq.enqueue_options_t
dbms_aq.message_properties_t
Then define the properties you want.
You can find some information about them here:
http://www.psoug.org/reference/dbms_aq.html

Code sample to dequeue messages

I am looking for a code sample to dequeue messages from CRM OD? How do I retrieve the xml file after it is generated. Do I need to use a web service to retrieve that?
Preference would be to get the code snippet in java, but not necessary.
Thanks.

Hi,
I'm assuming you are referring to integration event messages? If so, then yes, you do need to use WS in order to retrieve them from CRMOD. Please refer to the CRM On Demand online help for Integration Events. It will provide details on downloading the WSDL file for Integration Events and the schema files which are required to process the events once they are retrieved. The WS User Guide contains details regarding the use of the GetEvents and DeleteEvents methods to retrieve and delete events from the queue.
Sorry, I don't currently have a code sample that I can provide.
Thanks,
Sean

Queues are not processed properly in BPM

Message Queue Blocking / MSGMNI Setting

Hi All,
Firstly, many thanks to all that can assists. I am currently getting Message Queue
Blocking messages in my ULOG files in my Tuxedo Application. (Tux ver 7.1 in Unix).
I am not sure what is causing this, but started to look into the Tux Config (UBB.MP)
and System message queue setting. Detailed as follows:
1)
Listed below is the system message queue setting:
set msgsys:msginfo_msgmni=2000
set msgsys:msginfo_msgmax=128000
set msgsys:msginfo_msgmnb=100000
set msgsys:msginfo_msgssz=256
set msgsys:msginfo_msgseg=25088
set msgsys:msginfo_msgtql=1550
set msgsys:msginfo_msgmap=1000
According to the BEA site, the MSGMNI is determined by this formula:
MSGMNI = MAXACCESSERS + 7 + (no. of servers with REPLYQ) + (no. MSSQ sets) - (no.
of servers with MSSQ sets)
The following is my current Tux. Config (UBB.MP) is set as :
- MAXACCESSERS = 2300
- Each servers (4 types in total) has its own REPLYQ and RQADDR.
- The same type of servers are set the same across 4 application servers.
Hence, my MSGMNI should be a minimum 2339 (ie. MSGMNI = 2300 + 16 + 16 - 0 = 2339).
But my current MSGMNI is 2000.
Would this contribute to my Message Queue Blocking?
Is my understanding correct and is this something I should change to avoid Message
Queue Blocking? Any helps and advice is much appreciated.

Malcolm,
Your information and explanations behind these error messages are very useful.
It allow me to further understand Tuxedo internal processing and at the same time
give me a chance to start analysing these fields.
I am reluctant to ask further questions at the mean time. I will use your suggestions
as a starting point.
I will certainly keep you posted of the outcome when I have made the changes in
my UBB config and machine parameters.
Many thanks with your help/explanations Malcolm. It helps alot!
Cheers.
David.

Hi David,
The MSGTQL reference you give (Solution S-00488) refers to the BEA MessageQ
product
and is not relevant to Tuxedo.
The error messages indicate that the queue buildup is probably due to
a restartable
server failing. What happens is this:
When a restartable server fails its IPC queue remains in place and continues
to
receive messages (which will be processed when the server restarts).
Depending
on the time taken to restart, the queue could become full and unable
to receive
any more messages, and this is probably why you got the message CMDTUX_CAT:1380
indicating that the BRIDGE process was unable to put a message on the
server's
queue.
A server is only restarted when the BBL does a SANITYSCAN check. If,
for example,
your SANITYSCAN interval is 300 seconds and your server fails immediately
after
the previous scan, then there will be a delay of almost 5 minutes before
the failure
is detected and the server restarted - plenty of time for the queue to
fill up.
There are a few things you could do:
The key thing would be to find out why the server is failing, and fix
the problem.
If this is not possible immediately, consider some of the other ideas
below.
Have several servers form an MSSQ to service this queue; then if one
fails the
others will continue processing the messages while the failed server
restarts
(this assumes, of course, that your application does not require the
messages
to be processed in strict order through the server).
Reduce the SANITYSCAN interval (but don't make it too small). This would
reduce
the average time taken to restart the server.
Increase the size of the IPC queue (MSGMNB) so that it can hold more
messages.
I'm not sure why you got a LIBTUX_CAT:1485 message, but this could be
due to a
BRIDGE failure as a result of the congestion.
The NETLOAD parameter would reduce the number of messages going to the
remote
machine, but only if the local machine offers the same service. If the
remote
machine is the only source of the service then NETLOAD will have no effect.
I
recommend you do a search of this newsgroup for postings on "load balancing"
there's some good stuff which will explain how load balancing works.
Depending how things go, it might not be a bad idea to open a case with
BEA Support
and ask for guidance (remember to submit your ubbconfig (or preferably
do a tmunloadcf)
together with the complete ULOGs from both the master and the slave machine).
Hope this helps some.

Malcolm.

Hi Malcolm,
Thank you for your reply. Interesting point you have made about theMSGTQL
value.
Based on your suggestion I went hunting around the BEA site and found
the following
snipplet:
"- The MSGTQL parameter must be set to a value greater than or
equal to the MSGMNI setting."
(http://support.bea.com/application?namespace=askbea&origin=ask_bea_answer.jsp&event=link.view_answer_page_solution&answerpage=solution&page=msq/S-00488.htm)
If the above point is valid, then my MSGTQL is definitely way too low.
IF this
be the case, would you know of a method to work out what my MSGTQL bytes
value
should be?
Additionally, I have looked at other parameters which I could tune,and
would
adding a NETLOAD parameter in the *MACHINES section will reduce remote
servers
call? Which potentially, maybe reduce message queue blocking?
FYI:
The error messages I am seeing in my ULOG file are:
"LIBTUX_CAT: 1477 : ERROR .SysServerDied
LIBTUX_CAT: 1476 : ERROR: .SysServerRestarting"
Which then leads to message queue blocking
"CMDTUX_CAT: 1380 : ERROR: Message queue blocking prevented delivery,
Qaddr=..."
and potentially "LIBTUX_CAT: 1485 .SysNetworkDropped."
Many Thanks. Hope to hear from you (Malcolm) or other parties out there
that can
assists.
Thanks.
David
