Database adapter BindFault and Domain log entry

Question

Dear All,
SOA/BPEL - 10.1.3.1
I am hoping that someone can point me in the right direction to getting to the root cause of an error that we occassionally encounter in production with a database adapter service that inserts a record into an Oracle database.
The database adapter step reports:
"Faulted while invoking operation "insert" on provider "DB_INSERTAR_MSISDN"":
<fault>
<bindingFault xmlns="http://schemas.oracle.com/bpel/extension">
<part name="summary">
<summary>null</summary>
</part>
</bindingFault>
</fault>
</messages>
"{http://schemas.oracle.com/bpel/extension}bindingFault" has been thrown.
<bindingFault xmlns="http://schemas.oracle.com/bpel/extension">
<part name="summary">
<summary>null</summary>
</part>
</bindingFault>
In the domain log, at the same time and the same BPEL flow, I see an entry like:
<2010-02-04 15:16:54,235> <INFO> <default.collaxa.cube.ws> <AdapterFramework::Outbound> file:/opt/oracle/product/10.1.3.1/OracleAS_1/bpel/domains/default/tmp/.bpel_ServiciosRed_1.5_fa24eb00ffacca13b39ce7cdeeee537e.tmp/DB_INSERTAR_MSISDN.wsdl [ DB_INSERTAR_MSISDN_ptt::insert(MsisdnCollection) ] - Using JCA Connection Pool - max size = <unbounded>
I am assuming that the two are related -- but I don't know how to get to the root cause - is it a connections issue to the database? have we exceeded maximum allowable connections?
Any assistance or pointers you can provide is greatly appreciated.

Hi UserN,
Thanks for the pointers. It has been a while since I attended the BPEL course, and since then I haven't had to administer any connection pools, I've just used what has been set-up by another team.
When I open the BPEL project, and look at the database adapter using the wizard, I see that the JNDI location specified as "eis/DB/HPPOMV". I see this again in the wsdl associated with the DB adapter, with the following: UIConnectionName="HPPOMV"
I have logged into EM, but I am not 100% sure that I am looking at the correct connection pool. I have navigated to "JDBC Resources" tab. Under the Data Sources section I see a list, but none of these has a JNDI location of "eis/DB/HPPOMV".
The closest match is "     jdbc/HPPOMV", with connection pool attributes of:
Initial size of Connection Cache 0
Minimum Number of Connections 0
Maximum Number of Connections 100
Connection Retry Interval (seconds) 1
Maximum Connection Attempts 3
Maximum Number of Statements Cached 0
Have I made my way to the right connection?
I am monitoring this pool, but the "connection in use" has not got anywhere near 100.
Edit:: is there anyway to monitor/record the connection pool usage? We normally investigate these errors the following day, by which time any connection pool issues may have gone. I don't really have time to watch the screen refresh every 30 seconds.
Thanks - Anit
(At the moment I am reading through the BPEL training material to review the steps I performed in class).
