Creating a OJMS topic and connecting to BAM

Question

Hi,
I have in our database created a topic for errors:
BEGIN
dbms_aqadm.drop_queue_table('IPLERRORQTAB',true);
END;
BEGIN
sys.dbms_aqadm.create_queue_table (
queue_table => 'IPLERRORQTAB'
, queue_payload_type => 'SYS.AQ$_JMS_MESSAGE'
, sort_list => 'PRIORITY,ENQ_TIME'
, comment => ''
, multiple_consumers => TRUE
, message_grouping => DBMS_AQADM.NONE
, storage_clause => 'TABLESPACE OJMS LOGGING'
, primary_instance => '0'
, secondary_instance => '0');
COMMIT;
END;
BEGIN
sys.dbms_aqadm.create_queue(
queue_name => 'IPLERROR'
, queue_table => 'IPLERRORQTAB'
, queue_type => sys.dbms_aqadm.NORMAL_QUEUE
, max_retries => '5'
, retry_delay => '0'
, retention_time => '0'
, comment => '');
END;
BEGIN
sys.dbms_aqadm.start_queue(
queue_name => 'IPLERROR'
, enqueue => TRUE
, dequeue => TRUE);
END;
DECLARE
subscriber SYS.aq$_agent;
BEGIN
subscriber := sys.aq$_agent (
name => 'BAM',
address => NULL,
protocol => NULL);
DBMS_AQADM.ADD_SUBSCRIBER (
queue_name => 'IPLERROR',
subscriber => subscriber);
END;
Then in the BAM Architect defined the following:
TopicConnectionFactory Name: java:comp/resource/ojms_ipl/TopicConnectionFactories/IPLERRORQTAB
Topic Name: java:comp/resource/ojms_ipl/Topics/IPLERROR
Durable Subscriber Name (Optional): BAM
In the enterprise Link i have created a connection between a Oracle BAM message receiver and a grid.
When i try the connection I get the following error:
IMessageSourceReceiver->messageReceive: javax.naming.NameNotFoundException: java:comp/resource/ojms_ipl/TopicConnectionFactories/IPLERRORQTAB not found

Can anyone see where the error might be?

Hi,
I solved the problem for him, it was a name resolution problem.
Machine setup:
machinebam.domain888.com - hosts bam
machineias.domain0101.com - hosts ias
The machine "machineias.domain0101.com" seems to be installed without the domain name (FQDN)
This means that when the machinebam.domain888.com send the OPMN request to lookup the JMS setup:
POST http://machineias.domain0101.com:6004/connect HTTP/1.1
Content-Length: 0
OPMNtype: pm
OPMNrequest: /dump?type=dms&dmsarg=[nountype=opmn_ias_instance&format=xml]
The response is without the FQDN;
HTTP/1.1 200 OK
Content-Length: 26486
Content-Type: text/html
Response:
<?xml version='1.0'?>
<!DOCTYPE pdml>
<pdml version='9.0.4' name='opmn' host='machineias' id='26954' timestamp='1173813385745'>

<metric name="port.value">
<value type="integer"><![CDATA[12604]]></value>
</metric>
This means that the name translation fails, ie a ping to machineias from machinebam.domain888.com fails.
The solution is either of:
- reinstall iAS with the domain suffix
- add all the domains to the DNS suffix lookup list (in TCP IP advanced settings for windows)
- add the host in %systemroot%\system32\drivers\etc\hosts
Ha en bra dag!
