SQLSTT 72000...

Question

We have purchased a product called Access Manager for DB2 and installed it on our AS400. This gives us the connectivitiy to Oracle server with which we do the Warehouse management software interface using our legacy system on AS400.
I have written several programs in SQLRPGLE and not quite sure as to how I can handle errors coming out of Oracle server.
As per my knowledge in my programs, I do
declare cursor
open cursor
fetch
dow look for sqlstate
fetch next row
enddo
close cursor
I am also new to this much of SQL.
Now, my programs are running in production and works just fine if we don;t have any issues with oracle server (database server down etc.).
My question is if the database server goes down for any reason, my SQLRPGLE progam starts giving me cursor not open errors, the actual error is as follows:
Connection to relational database HJAWCD1 already exists.
ARDUPAR: ARDUPAR: rc=-1(OCI_ERROR) from OCIStmtExecute when asking for
Describe-Info
ARDUPAR(1): ORA-03114: not connected to ORACLE
ARDAROC: rc = -1 from parse
SQLSTATE class unknown - SQLSTATE 72000, SQLCODE -969.
Cursor SEHOST not open.
Cursor SEHOST not open.
Cursor SEHOST not open.
So although, the connection exist between the AS400 and Oracle server as suggested from first statement, but then the cursor is giving me problems of not opening.
what I would like to know is how do I check in my SQL statement the error and somehow reconnect and open the cursor again.
Please help in this regard, since I am not finding any help from iseries world becuase no one seems to have knowledge about this product that we have installed and I don;t have too mcuh of documentation on the product nor do I have any sample handling messages program using RPGLE between oracle and AS400 using the product.

Also one more thing which is bugging me for a long time about the Access Manager messages. Sometimes, during the same session on AS400, user gets an unidentified type of error in the job log and the connection to ARD is still there but the session can no longer send transactions to Oracle sever using the link and I couldn't figure out how to atack that issue.
In the job log I get this:
Connection to relational database HJAWCB1 already exists.
Ownership of object ORAARD_V in QTEMP type *USRSPC changed.             
Library ORAAM400 added to library list.
Library ORASRV0002 added to library list.
Ownership of object ORAARDCNTX in QTEMP type *USRSPC changed.           
Ownership of object SP2 in QTEMP type *USRSPC changed.                  
Pointer not set for location referenced.
Exception MCH3601 of severity 40 received during AccessManager execution.

program.
ROLLBACK is required.
ROLLBACK is required.

It all starts with that mesage "Pointer not set for location referenced". And the details on that message says:
Message ID . . . . . . : MCH3601 Severity . . . . . . . : 40

To module . . . . . . . . . : SLSLGET
To procedure . . . . . . . . : slslgetmeta
To statement . . . . . . . . : 1
So, it is definitley something with the access manager software that we have installed on the as400 which issues this message for some un identified reason. Does Oracle have any patch for Access Manager version 10.2.0.1.0
Please help, how to resolve this issue???
