Accessing Oracle advanced queuing from forms6i

I have a 3-tiered architecture where my forms run on a different server from the rest of my applications. I have a
UNIX process that produces warnings for specified users who are accessing forms6i on their PC's. The process
enqueues these warnings to an Oracle queue. I need a way for the form to dequeue this information. Is there a way for
the form to run a Java process in the background so that the form would surrender screen control to the warning process
when warranted? ................Can the dequeue logic be coded into a forms procedure or a stored procedure in the
database and accessed directly from the form and run in the background?..........In general, can forms run processes
in the background?................Can anyone point me toward some documentation that can help me?.....................
Any help with any or all of the above would be greatly appreciated.

John,
there is no direct support for AQ in Forms. Check out this document, which is stil valid. Note the set_custom_item_property in 6i is named set_custom_property!

Propagation between queues in Oracle Advanced Queuing

We would like to connect two queues that reside in different database schemas/instances.
We try to use the propagation feature of Oracle to achieve this.
The queue-type is the same for both queues.
Enqueuing is done with a recipient list in order to set multiple local subscribers for the messages that are put onto the queue.
We would like to propagate between queues without changing the applications that write to originating queue and the other applications that read from the target queue.
During our research we only found ways where we need to change the application that writes onto the queue, which is not acceptable for us. Also the list of subscribers needs to be different based on the message.
Therefore I have the following question:
- is there a way to set up propagation between queues in a way where we don't need to modify the sending application?
- if not, is there a different way to connect two queues via a subscriber/consumer?

Oracle8i for Linux does have AQ, although I haven't evaluated it
yet. If you're still having trouble with the install, make sure
you get the patch. A quicker and easier way to get Oracle8i up
cheaply for evaluation is to download the NT version. I'm
evaluating Oracle8i for both Linux and NT and the NT version is
more stable.
I would really appreciate hearing about your experiences with AQ
on Oracle8 (8.0.4.3). I have several projects that we have been
considering using AQ with. Please send me an email and tell me
what problems / work-arounds you found.

Integration Oracle Advance Queue with OSB

We are doing integration for Oracle Advance Queue with OSB.
I created an AQ adapter in Jdev and generate the WSDL and XSD.
I imported both WSDL and XSD in OSB Project.
When i am configuring the business service and selecting the WSDl i am not able to select Binding and ports, is it due to any issue in WSDL?
Please help.
Thanks,
Mihir Panda

Hi again,
I made some adjustments to your wsdl. I added the binding part and its reference to the appropriate port.
Now I reckon, you should be able to do your thing:

Oracle advanced queuing

Hi,
I am new to Oracle Advanced queuing. I have a question.
After enqueue operation, the message can be retrieved by dequeue operation.
But, why do we need SCHEDULE_PROPAGATION ?
Do we use that when we are sending it to a totally differnt queue in someother remote database ?
Thanks,
Message was edited by:
user448390

Do we use that when we are sending it to a totally
differnt queue in someother remote database ?yes, partly true...SCHEDULE_PROPAGATION is used when we schedule propagation of messages to a destination identified by a Database Link.
DBMS_AQADM.SCHEDULE_PROPAGATION (
   queue_name          IN    VARCHAR2,
   destination         IN    VARCHAR2 DEFAULT NULL,
   start_time          IN    DATE     DEFAULT SYSDATE,
   duration            IN    NUMBER   DEFAULT NULL,
   next_time           IN    VARCHAR2 DEFAULT NULL,
   latency             IN    NUMBER   DEFAULT 60,
   destination_queue IN VARCHAR2 DEFAULT NULL);
destination_queue -- Name of the target queue to which messages are to be propagated in the form of a dblink.
Messages may also be propagated to other queues in the same database by specifying a NULL destination. If a message has multiple recipients at the same destination in either the same or different queues, the message is propagated to all of them at the same time.
Hope this will help..
Thanks

JPA + Oracle Advanced Queues

Hi,
Has anyone managed to share a transaction between the toplink JPA implementation and the Oracle Advanced Queues interface (which uses jdbc; java.sql.connection) in a J2SE environment?
Running both in a J2EE environment is working fine, as both of them are using the JTA provided by OC4J.
I've been trying to use JOTM as a lightweight JTA provider, but without any success at this point. JPA is using the datasource created by jotm (that includes the jotm transactionmanager), but it seems like JTA transactions are being ignored by the EntityMaanger at this point...
regards,
Bert

Hi! I'm not a dev, but I know for sure ODP.NET does not support AQ. You might wanna have a look at Oracle Object for OLE (OO4O). It supports AQ and can be used in both VB.NET and C# through COM Interop. Of course, the performances will not be as good as ODP.NET tho.
Have a nice one.

Weblogic JMS bridge between Weblogic and oracle Advanced Queue

Hi,
We are facing some issues when we are trying to integrate with Oracle AQ JMS through Weblogic.
We have configured a Foreign AQ server which points to the oracle Advanced Queue and we are trying to create a Weblogic JMS bridge between AQ and weblogic. The bridge works perfectly if create the connection factories and bridge destinations with NonTX mode. The issue is with XA mode. Also we have deployed the Resource adaper for XAResource to use XA transactions.
No help is available for the exception on google too :)
Following is the exception we are getting.

Oracle Advanced Queuing - Propagation problem - 11g

Hi,
I have a problem when propagation messages between queues. When the message is propagated, it stays on the source queue with READY state.
I have created two queues on 11g with a propagation rule that any message from queue A are sent to queue B. My problem is that the message from the source queue stays in the source queue even after propagation, which isn't what I was expecting. The problem doesn't occur if the queues are on a different database. This problem only happens if the queues are on the same database.
the script I use is this:
For USERB (which has the destination queue)
create type EVENT_MESSAGE as object (
eventsource VARCHAR2(30),
eventname VARCHAR2(255),
eventid NUMBER(19,0),
message CLOB
DECLARE
an_agent sys.aq$_agent;
BEGIN
-- create the publish/subscribe queue table
dbms_aqadm.create_queue_table(
queue_table => 'DESTINATION_QUEUE_TABLE',
queue_payload_type=>'EVENT_MESSAGE',
sort_list => 'ENQ_TIME',
message_grouping => DBMS_AQADM.NONE,
multiple_consumers=>true
-- create the queue
dbms_aqadm.create_queue(
queue_name => 'DESTINATION',
queue_table => 'DESTINATION_QUEUE_TABLE',
queue_type => DBMS_AQADM.NORMAL_QUEUE,
max_retries => 5
dbms_aqadm.create_aq_agent(agent_name =>'DEQUEUE_AGENT');
an_agent := sys.aq$_agent('DEQUEUE_AGENT', null, null);
dbms_aqadm.enable_db_access(
agent_name => 'DEQUEUE_AGENT',
db_username => 'USERB'
dbms_aqadm.add_subscriber(
queue_name => 'DESTINATION',
subscriber => an_agent,
queue_to_queue => FALSE,
delivery_mode => DBMS_AQADM.PERSISTENT
-- start the queues
dbms_aqadm.start_queue('DESTINATION');
END;
For USERA
create type EVENT_MESSAGE as object (
eventsource VARCHAR2(30),
eventname VARCHAR2(255),
eventid NUMBER(19,0),
message CLOB
BEGIN
-- create the publish/subscribe queue table
dbms_aqadm.create_queue_table(
queue_table => 'SOURCE_QUEUE_TABLE',
queue_payload_type=>'EVENT_MESSAGE',
sort_list => 'ENQ_TIME',
message_grouping => DBMS_AQADM.NONE,
multiple_consumers=>true
-- create the queue
dbms_aqadm.create_queue(
queue_name => 'SOURCE',
queue_table => 'SOURCE_QUEUE_TABLE',
queue_type => DBMS_AQADM.NORMAL_QUEUE,
max_retries => 5
-- start the queues
dbms_aqadm.start_queue('SOURCE');
-- create the propagation
dbms_aqadm.add_subscriber(queue_name => 'SOURCE',
subscriber => sys.aq$_agent('DEQUEUE_AGENT','USERB.DESTINATION',null),
queue_to_queue => true);
dbms_aqadm.schedule_propagation(queue_name => 'SOURCE',
start_time => sysdate,
latency => 25,
destination_queue => 'USERB.DESTINATION');
END;
When I enqueue a message to the source on USERA with this:
declare
rc binary_integer;
nq_opt dbms_aq.enqueue_options_t;
nq_pro dbms_aq.message_properties_t;
datas EVENT_MESSAGE;
msgid raw(16);
begin
nq_pro.expiration := dbms_aq.never;
nq_pro.sender_id := sys.aq$_agent('ENQUEUE_AGENT', null, null);
datas := AGEAS_EVENT_MESSAGE('message','eventname',1,null);
dbms_aq.enqueue('SOURCE',nq_opt,nq_pro,datas,msgid);
end;
The message is propagated to the destination queue, no problem, but the message state on the source queue is kept as ready. I would have expected it to be marked as processed and disappear from the queue table.
When I look at the AQ$_SOURCE_QUEUE_TABLE_S the I see these records:
     QUEUE_NAME     NAME     ADDRESS     PROTOCOL      SUBSCRIBER TYPE
     SOURCE     (null)     "USERB"."DESTINATION"@AQ$_LOCAL     0     1736
     SOURCE     DEQUEUE_AGENT     "USERB"."DESTINATION"     0     577
Can anyone help?

2. Be sure your selinux and firewal disable on linux machine
3. Add your IP and hostaname to your windows C:\WINDOWS\system32\drivers\etc\hosts file
4. Add your url to your trusted site on windows
5. Use IE7 or check below note to can use certified browswer and access EBS

Unable to access Oracle VM Manager from browser

Hi,
I am unable to access the Oracle VM Manager from my browser at any of the url's e.g. /em; /OVS; /apex
I can connect to my server via putty, so I know the IP address that I am using is correct.
In the /var/ovm-manager/oc4j.log file I get the following message:
ERROR J2EE HTTP-00004 Internal error raised tyring to instantiate web-application: webapp defined in web site OC4J 10g (10.1.3) Default Web Site. Application: datatags does not exist. Error creating Web application: webapp
The oc4j service is running and the ovs-agent service is running but I cannot connect.
I am new to Oracle VM and Linux for that matter so it is entirely possible that something is not configured correctly somewhere
I'll appreciate it if anyone can assist
Thanks

Try this command from the console or SSH to the server:
service iptables stop
If you can then access the URLs you will need to modify iptables to allow port 8888
I think this is the command:
iptables -I INPUT -p tcp --dport 8888 -j ACCEPT
then:
service iptables start
Then try to connect again.

Accessing Oracle LDAP Service from Microsoft SQL*Server2000

Hi
We are trying to link onto the Oracle LDAP service from a stored procedure in an SQL*Server 2000 database. But we are not able to succeed.
Anyone who can share some experience with us on the topic? Is it at all possible to do what we are trying to do? Must we install some driver software (or the like) at the SQL*Server side? Or do we have to write a Java application instead that uses JNDI to access OID and then connect to the SQL*Server?
Any help is appreciated.
