Update Database using Materialized Views

I have a need to update the database across the firewall (on a partner network). Are there any issues/problems with this approach like performance, security,etc. I do not want to use dblinks.

Materialized views generally don't work too well without a database link between the machines-- in fact, they don't work at all. Oracle replication is built around the assumption that the databases involved can communicate with each other.

Can I use OLAP kind of functionality without installing OLAP ( using materialized views etc)

Hi,
Can OLAP cube be implemented without having ORACLE OLAP installed? As per my understanding, cubes are something which keeps aggregate data. So can I just use materialized view functionality ( which is already there in Oracle)?
Which other Oracle object can I use without installing ORACLE OLAP ( Dimension etc?)
Thanks a lot.
Nitin

If you mean by implementing an OLAP cube, you mean setting up reports for various summary level data analysis, it is possible to query materialized views to get the same data in some cases. A position paper that describes the advantages of the OLAP Cube v. among other things standard materialized views may be found at this URL: http://www.oracle.com/technetwork/database/options/olap/olap-wp-12c-1896136.pdf?ssSourceSiteId=ocomen
I also would recommend posting this question on the general database forum (General Database Discussions) as well.
Hope this helps,

Data Replication Between Sqlserver and Oracle11g using materialized view.

I have Sqlserver 2005 as my source and oracle11g as my target.I need to populate the target daily with change data from source.
for that we have created a dblink between sqlserver and oracle and replicated that table as a Materialized view in Oracle.
problem we are getting here is Fast refresh option is not available.each day it will pick full data from the source.
is there any way to use Fast refresh in this scenario??
Thanks in advance.

Best approach - using materialized views

Hi
We are using materialized views for structuring complex business data.
These views get refreshed every night. However, the refresh jobs runs slow in some cases.In such scenarios, the job would still be running while client applications (JDBC) try to access data from the views. This would result in client calls to wait for a long time or to timeout. I would like to know what is the best approach in such scenarios to ensure data availability and performance?
Thanks

You can use a Fast Refresh if it meets the restrictions. You need to have a MATERIALIZED VIEW LOG created on the source table(s).

Updating one table is updating ALL the materialized views

We have a number of tables and also a number of materialized views that are interconnected. For some unexplained reason, when we update one table that should refresh one materialized view, all the materialized views are refreshed. It's causing massive bottlenecks on our system and we can't find the cause. Does anyone have any thoughts?

"when we update one table that should refresh one materialized view, all the materialized views are refreshed" --If that table is used in the creation of all materialized views,then it will try to refresh all of them..(ON COMMIT REFRESH)

Need advise : Risks of using materialized views

Hi -
I need some advise on whether using a materilzied view can help in teh folloiwng scenario.
Scenario : You have a large tables which has sy 60 million rows, This is a demand management application which accesses this data at various aggregate levels (It is not using any OLAP functionality). The worksheets that is used to display the data takes up hours to execute on.
To solve teh above scenario I created partitions on the base table say by time and the on top I created some materialized views. This gave me tremendoud gain in performance for the worksheets.
Question is : Will Materialzied views help in situations say where the user changes the data in the worksheet and another user tries to query the changes will the materialized view be able to show the changes or do I need enforce a fast refresh. all the standard option of enabling query rewrite and fast refresh are enabled. The parameter for query_rewrite_integrity is set to Trusted.
Please advise what could be teh pitfalls in managing such huge data where some of it changes infrequently.

Hi Arch,
Will Materialzied views help in situations say where the user changes the data in the worksheet and another user tries to query the changes will the materialized view be able to show the changes or do I need enforce a fast refresh.That depends on your "stale tolerance":
http://www.dba-oracle.com/t_materialized_view_fast_refresh_performance.htm
pitfalls in managing such huge data where some of it changes infrequently. If it does not change frequently, then it's just a matter of extra disk space for the materializations. I have more notes here:

Hi,
First Run Application module and confirm whether model project is OK,Cause for the Error is Caused by: java.sql.SQLSyntaxErrorException: ORA-00972: identifier is too long
check:
Issues with table/column name length
identifier is too long
I guess following error occurred because above issue
JBO-26080: DMLException
Cause: An unexpected exception occurred while executing the SQL to fetch data for an entity instance or lock it.
Action: Fix the cause for the SQLException in the details of this exception.

Hi,
you could use Dynamic SQL /Execute immediate to run DDL from a stored procedure.

Could you please tell why do you want to create a materialized view in stored procedure ?
How frequently you will runt this procedure . It would is better to create a MV once and use it.

any inputs on this ll be of great help.
Thanks in advance.

How to update database using Service in 11g

Please some one provide the knowledge, how i will update database from a form and form is having multiple rows and column and and all are having different or same value.
e.g. we have having clientName table and having column(clientname, legalContact, selfservice,usertype,details),
We can search the data from clientName, now user can change other information except clientName can not be change but other information can change. now how i will update users changed value.

Hi ,
If you are looking to update the fields for a user such as description , telephone number etc then the following service needs to be used :

Unable to update database using a remote bean call

We have a system, in which one of the EJBs (say, local EJB) in one
system remotely call an ejb (say, remote EJB) on another system. The
problem is the that the remote EJB is unable to database with any
changes when its method was invoked by the local EJB.
We first call a set method which is supposed to update the DB. Then we
call the get method which returns the recently updated value. However
the data is not stored in the DB. The get method seems to retrieve the
data from the cache. There is no exception thrown.
However there is no issue with the remote EJB. If we call the method
locally, it DOES update the database. I dont know if it has to do
anything with the java security policy defined. We use Weblogic 6.1
SP3.
We have a release in another 2 days and any help on this will be
appreciated.

UPDATE Database (using Schema) based on current START_DATE_TIME

Hi,
I am using the TestStand Schema and a MYSQL datababse.
I have added a new table the MYSQL database that comes with TestStand. I am using the database tools to insert some local variable results into this table.
I also add the start date and time to this table, using
Str(RunState.Root.RunState.Sequence.Locals.StartDate.Month) + "-" +Str(RunState.Root.RunState.Sequence.Locals.StartDate.MonthDay) + "-" + Str(RunState.Root.RunState.Sequence.Locals.StartDate.Year) + " " + Str(RunState.Root.RunState.Sequence.Locals.StartTime.Hours) + ":" +Str(RunState.Root.RunState.Sequence.Locals.StartTime.Minutes) + ":" + Str(RunState.Root.RunState.Sequence.Locals.StartTime.Seconds)
I am trying to use the Schemato update the a colum with the parent ID, so I have it set up as a foreign key. I can get this to work when I use hardcode the the date/time in the SQP statement.
Example:
"UPDATE UUT_CTO_DATA SET ID=? ,UUT_RESULT=? where START_DATE_TIME='2009-03-20 15:13:24'"However I would like to change this so the SQL statement using the TestSTand Variables to figure out which is the current record to update...Is this possible..All help is greatly appreciated.
Regards,
Don1.

Hi Mark,
Thanks for the quick response,Some comments below:
I need some clarification on the issue and your progress. In the first poast you had said "I can get this to work when I use hardcode the the date/time in the SQP statement." When you hardcode the date and time, does it update the ID & UUT_RESULT columns for all devices in a bath?
When I hardcode the update SQL statement with a specific date, Example: "UPDATE UUT_CTO_DATA SET ID=? ,UUT_RESULT=? where START_DATE_TIME= '2009-03-24 10:31:13'" , it will update the ID & UUT_RESULT columns for all devices in a batch, (I manually delete it from the MYSQL database after each device in the batch to confirm it updates on subsquent runs)
So do you think it now looks like my original SQL statement is somehow incorrect for all bar the first device in the batch?
I did try the following:
Created a StationGlobal called Test.
Assigned it as follows, to ensure it matches the database record format ('2009-03-24 10:31:13')
StationGlobals.Test =Str(RunState.Root.RunState.Sequence.Locals.StartDate.Year) + "-" +Str(RunState.Root.RunState.Sequence.Locals.StartDate.Month,"%02i") + "-" + Str(RunState.Root.RunState.Sequence.Locals.StartDate.MonthDay,"%02i") + " " + Str(RunState.Root.RunState.Sequence.Locals.StartTime.Hours,"%02i") + ":" +Str(RunState.Root.RunState.Sequence.Locals.StartTime.Minutes,"%02i") + ":" + Str(RunState.Root.RunState.Sequence.Locals.StartTime.Seconds,"%02i")
Change my SQL statement to "UPDATE UUT_CTO_DATA SET ID=? ,UUT_RESULT=? where START_DATE_TIME= '"+StationGlobals.Test+"'"
As before it updated for the first device in the batch and none of the rest.
Also, which version of TestStand are you using?
I am using TestStand 4.1.1
Thanks & Regards,
Don1

Update database using check boxes

I have a query region that produces a checkbox and an associated line with the checkbox. The data in the database that is a "Y", produces a checked box.
select check_box_seq,
htmldb_item.checkbox(1,is_it_checked,decode(is_it_checked,'Y','CHECKED')) D,
check_box_text R
from check_box_tbl
What I need to happen is to change one or more check boxes. I have a MultiRow Update process, with a process point of On Submit - After Computations and Validations with a PL/SQL conditional processing of:
FOR I in 1.. HTMLDB_APPLICATION.F_F01.COUNT LOOP
update table check_box_tbl set is_it_checked = Y
where check_box_seq = htmldb_item.application.g_f01(i);
END LOOP;
But the data in the database does not change. I have read numerous discussion on this thread but I have not found exactly what I need or can not recognize it.
How can I get the data in the database to change when I either change a checked box or after I have changed all boxes and then press the SUBMIT.

I am having a similar problem that I cannot find the answer to. (See my process below). I don't think that the process is "grabbing" the checked values in the SDN column. It is using NULL, so therefore no rows are being inserted in the table. Shg_id and SDN are both primary keys in this table, so I need to insert both. Shg_id has an assigned value already.
My process is this:
DECLARE

Updating records using a view

Hello,
I have two tables, ROAD and ROAD_PARSED. I have created a view ROAD_V that contains the fields from ROAD and ROAD_PARSED that I want to to update in ROAD.
CREATE VIEW ROAD_V AS SELECT A.ID, A.PREF, A.NAME, A.TYPE, A.DIR, B.PREF "BPREFIX", B.NAME "BNAME", B.TYPE "BTYPE", B.DIR "BDIR"
FROM ROAD A, ROAD_PARSED B
WHERE A.ID=B.ID;
Then I entered my update statement: UPDATE ROAD_V SET PREF=BPREFIX, NAME=BNAME, TYPE=BTYPE, DIR=BDIR;
I got this error: +"ORA-01779: cannot modify a column which maps to a non key-preserved table".+ ROAD has a spatial index on ID and ROAD_PARSED has a unique on ID, and there are not other unique fields in my table. How do I go about adding a unique index to ROAD when i have already indexed ID?
The only thing I can think of to work around it is to create a new field in ROAD, populate it with a sequence starting at 1 and assign a unique index to it, insert those values into ROAD_PARSED, and then run the update. This sounds unnecessary...but is it the right way?
