The source table that is in another database changed. But the view on my database where the materialized view exist has not changed. I want to confirm from where is data coming in this view

Error while creating materialized view which using database link
Helo!
I'm getting error "ORA-00942: table or view does not exist" when I want to create materialized view.
Details:
1. On destination database I create a database link:
CREATE DATABASE LINK SDATABASE
CONNECT TO MYUSER
IDENTIFIED BY MYUSERPASS
USING 'ORCL';
=> Command "SELECT * FROM TABLE1@SDATABASE" returns data normally!
2. On source database I create MATERIALIZED VIEW LOG:
CREATE MATERIALIZED VIEW LOG
ON TABLE1
WITH PRIMARY KEY
INCLUDING NEW VALUES;
3. Now, when I want to create MATERIALIZED VIEW on destination database:
CREATE MATERIALIZED VIEW TABLE1
REFRESH FAST
START WITH SYSDATE
NEXT SYSDATE + 1/1440
WITH PRIMARY KEY
AS SELECT * FROM TABLE1@SDATABASE;
...I get error "ORA-00942: table or view does not exist"!
How is that possible if command "SELECT * FROM TABLE1@SDATABASE" returns data normally?
Thanks,
VorancAnd, I'm using Oracle 10g.

How to refresh materialized view by trigger
hi,
im having a problem in refreshing materialized view through a trigger.
CREATE OR REPLACE TRIGGER L_TRG_MARC_TEST
BEFORE DELETE OR INSERT OR UPDATE ON MARC_BOOK_B_ENG
BEGIN
DBMS_MVIEW.REFRESH('TITLE_ENG_MV','C','',TRUE,FALSE,0,0,0,TRUE);
END;
Trigger created.
SQL> DELETE FROM MARC_BOOK_B_ENG;
DELETE FROM MARC_BOOK_B_ENG
ERROR at line 1:
ORA-04092: cannot COMMIT in a trigger
ORA-06512: at "SYS.DBMS_SNAPSHOT", line 849
ORA-06512: at "SYS.DBMS_SNAPSHOT", line 832
ORA-06512: at "LIBQAL1.L_TRG_MARC_TEST", line 2
ORA-04088: error during execution of trigger 'LIBQAL1.L_TRG_MARC_TEST'
plz tell me how to refresh materialized view thru trigger,,and what is wrong in above mentioned situation.
RegardsDBMS_MVIEW.REFRESH implicitly commits. COMMIT is not permitted in triggers, as you can see, unless you use AUTONOMOUS_TRANSACTION.
Try
CREATE OR REPLACE TRIGGER L_TRG_MARC_TEST
BEFORE DELETE OR INSERT OR UPDATE ON MARC_BOOK_B_ENG
DECLARE
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
DBMS_MVIEW.REFRESH('TITLE_ENG_MV','C','',TRUE,FALSE,0,0,0,TRUE);
END; -

How to pull only column names from a SELECT query without running it
How to pull only column names from a SELECT statement without executing it? It seems there is getMetaData() in Java to pull the column names while sql is being prepared and before it gets executed. I need to get the columns whether we run the sql or not.
Maybe something like this is what you are looking for or at least will give you some ideas.
public static DataSet MaterializeDataSet(string _connectionString, string _sqlSelect, bool _returnProviderSpecificTypes, bool _includeSchema, bool _fillTable)
DataSet ds = null;
using (OracleConnection _oraconn = new OracleConnection(_connectionString))
try
_oraconn.Open();
using (OracleCommand cmd = new OracleCommand(_sqlSelect, _oraconn))
cmd.CommandType = CommandType.Text;
using (OracleDataAdapter da = new OracleDataAdapter(cmd))
da.ReturnProviderSpecificTypes = _returnProviderSpecificTypes;
//da.MissingSchemaAction = MissingSchemaAction.AddWithKey;
if (_includeSchema == true)
ds = new DataSet("SCHEMASUPPLIED");
da.FillSchema(ds, SchemaType.Source);
if (_fillTable == true)
da.Fill(ds.Tables[0]);
else
ds = new DataSet("SCHEMANOTSUPPLIED");
if (_fillTable == true)
da.Fill(ds);
ds.Tables[0].TableName = "Table";
}//using da
} //using cmd
catch (OracleException _oraEx)
throw (_oraEx); // Actually rethrow
catch (System.Exception _sysEx)
throw (_sysEx); // Actually rethrow
finally
if (_oraconn.State == ConnectionState.Broken || _oraconn.State == ConnectionState.Open)
_oraconn.Close();
}//using oraconn
if (ds != null)
if (ds.Tables != null && ds.Tables[0] != null)
return ds;
else
return null;
else
return null;

How can I send a message from database to a J2EE application?
How can I send a message from database to a J2EE application?
If I have a codetable in database that has new or modified values I have to refresh the codetable in my J2EE application.
Most effective way would be send a message to initiate a table reload from J2EE app, but I don't know how to do this.
Now I have a background thread that regular reads the table and looks for changes.http://www.oracle.com/technology/products/integration/bam/10.1.3/TechNotes/TechNote_BAM_AQ_Configuration.pdf
This document details how to create triggers on a table that send out JMS messages.
In this example, the messages are going to Oracle BAM.. your message could go to your J2EE application listening to its own topic/queue.
an alternative idea.
you could also just cache your lookup table with something like Oracle Coherence and than try to ensure that all changes to the lookup go through Coherence, so that you won't need to do notification from the db up to the application. the application and the lookup data management tool would be using the data grid for management of the lookup table data, and the data grid (coherence) would persist the lookup data changes back to the db. -

How to find out company code from a plant ?
Hello friends,
I have to modify a program that uses FM "BAPI_COMPANYCODE_GET_PERIOD". For that, we have to export company code ID. Currently it is hard coded with one company code. Now we want to make this program usable by all company codes. So instead of hard coding, I would like to dynamically find out company code based on the plant. So I want to know - how to find out company code from a plant ? Is there any table that has plant to company-code assignment data, or any other FM/BAPI to get this info ?
Thanks,
