DB Adapter: Message not picked up

Question

Hi,
I have an iConnect 10g working fine with the FTP adapter. Messages come through no problem. But now I'm trying to use the DB adapter to publish a message. I have the adapter running and cannot see anything wrong in the logs, but whenever I create and publish a message (and commit afterwards) I can the message appearing in the MESSAGEOBJECTTABLE and the AOTABLE, but the adapter doesn't pick it up.
What can cause this?

Hi,
Did you see any errors in the DB adapter log file? Connection errors?
What is your logging level on the adapters set to? In the adapter.ini file, set the "agent_log_level=2".
Merlin is correct regarding when your DB Adapter message is not published.
Some other checks to make are these:-
Log on via SQL*Plus to your publishing database, connecting to the OAI user (usually OAI/OAI) and do:-
select count(*) from oai.aotable;
and
select count(*) from oai.messageobjecttable;
If there is the same number of records on there, and your publishing adapter hasn't pick them up, then run this:-
select APPLICATIONTYPE from oai.messageobjecttable;
This should be the same as your publishing adapter name.
Hint: in adapter.ini check the entry for "application= "
e.g.
// Application (as created in iStudio) that this Adapter corresponds to.
application=DB1
If they are different, or if APPLICATIONTYPE is null, then this is caused because you need to specify the "srcAppName" when you call your publish
procedure.
If you send me a mail to [email protected] I'll send you a complete worked, yet simple, DB Adapter to DB Adapter example and code which may help you.
Rene,
It is worth noting that ordinarily, the OAI schema has absolutly nothing to do with a subcribing DB adapter. The OAI schema contains the AOTABLE and MESSAGEOBJECTTABLE (MOTABLE), and the AGENT package which creates the message for the publishing event. That is it. The OAI schema does not usually "consume" the subcribed message, and therefore should never end up in the AOTABLE or MOTABLE.
The target schema to where the subcribed DB message will be posted to is the schema you will define in the DB Adapters "adapter.ini" file.
Specifically the entries below this line in your adapter.ini
// Application (spoke) database schema #1 writer information
Do you have any errors in your log files? The message cannot have just disappeared. Your FTP Adapter must be throwing an error somewhere, or your DB Adapter must be complaining.
Please can you check you log files for both adapters. If there are any strange errors let us know.
What type of document are you trying to publish using the FTP Adapter? XML? D3L? If XML, then check out the post "istudio publish event & xml ftp adapter" on this forum.
Again, if you drop me an email, then I can send you my DB Adapter to DB Adapter example which may help.
