Help Understanding Query V$SESSION

Question

Hi,
Below is the query I am executing.
I would like to clearly understand what does it mean?
SQL> select program,machine,prev_sql_id from v$session where module = 'DCShipmentCompleteDaemon' and server = 'NONE';
PROGRAM MACHINE PREV_SQL_ID
[email protected] fc-api-rno1-101.rno1.amazon.com 8733zd08ytmj1
SQL> select sql_text from v$sqlarea where sql_id = '8733zd08ytmj1';
SQL_TEXT
select FCSKU_PROP_XML_ID, FCSKU, FCSKU_MODEL_VERSION, PROPERTY, DATA_SOURCE, XML, XML_CREATION_DATE_UTC, WAREHOUSE_ID, RECONCILIATION_STATUS from FCSKU_PROPERTY_XML where FCSKU = :fcsku and FCSKU_MODEL_VERSION = :fcsku_model_version and PROPERTY = :property_name and RECONCILIATION_STATUS = :recon_status order by XML_CREATION_DATE_UTC desc
Is the query “select FCSKU_PROP_XML_ID….” Shown above being executed by DCShipmentCompleteDaemon ?
Also, another question is how will the module name be registered in a Database or V$SESSION table more appropriately? Can 2 binaries having different names point to same module name?
Thanks,
Raja.

That indicates that the last statement executed by this program in the particular session was the SELECT statement you posted. There is another SQL_ID column in V$SESSION that would tell you the current SQL statement being executed by a session, assuming the session was active.

The module is set by the client application. So it is entirely possible for two different applications to set the same module name, for a program to change the module name repeatedly, etc. You can look at the DBMS_APPLICATION_INFO package to see how you can set the module and action for a session in your own code, for example.
