Use theREFRESH FAST ON COMMIT option
Example Steps
1. Create Materialized View Log
CREATE MATERIALIZED VIEW LOG ON table_name
WITH ROWID
     Col1
     Col2
     Col...
INCLUDING NEW VALUES
2. Create the Materialized View using the above[b] table_name in the SELECT
CREATE MATERIALIZED VIEW mv_name
REFRESH FAST ON COMMIT
WITH ROWID
AS
SELECT xxxxx

In SMO there is any option for run both ExecuteNonQuery and ExecuteWithResults.?

In SMO there is any option for run both ExecuteNonQuery and ExecuteWithResults query at simultaneously?

Hello,
First, in a client session nothing can run "simultaneously", all statements are executed in sequence. And what should
it be good for to run ExecuteNonQuery +
ExecuteWithResults; both executes the SQL batch, the only difference is, ExecuteWithResults returns a result?
But if you like, start one by one.

Installed LR 3.2, and export does not show any options for exporting to Smugmug, Facebook etc

I fresh installed LR 3.2 on a Windows 7 computer to try out tethering (which worked fine), but then tried to export the photos, but I don't have any options for exporting to non-harddrive based locations. The "export to" drop down at the top of the export page only has "hard drive" in it. The plugin manager says that plugins for SmugMug, Facebook, etc are all enabled.
Anyone have any ideas?
Thanks!
Mike

I found too that the publishing services work differently than the plug-ins. Not as intuitive, but work well just the same, For me I had to do the "set-up" for the Facebook publishing service a couple of times. I think this may have more to do with the Facebook security settings than with LR.

Do Not Disturb and Notifications
Push notifications appear in Notification Center and alert you to new information, even when the
associated app isn’t running. Notifications vary by app, but may include text or sound alerts, and
a numbered badge on the app icon on the Home screen.
Turn off all notifications: Go to Settings and turn on Do Not Disturb. When it’s turned on and
iPhone is locked, all notifications and calls are silenced, but alarms will still sound. You can set the
following options in Settings > Notifications > Do Not Disturb:
• Automatically turn on Do Not Disturb: Set the starting and ending hours for when you don’t
want to be disturbed. iPhone turns on Do Not Disturb during these hours each day.
• Allow some phone calls during Do Not Disturb: When Do Not Disturb is on, calls are silently sent
to voice mail. To allow some callers to ring through, tap Allow Calls From. You can allow calls
from your Favorites list or other Contacts groups you define. For information about Favorites,
see Chapter 25, Contacts, on page 100.
• Allow persistant callers to ring through: Turn on Repeated Calls. If the same caller (based on
their Caller ID) calls you twice within three minutes, iPhone will ring.
Turn an app’s notifications on or off: Go to Settings > Notifications. Tap an item in the list, then
turn notifications on or off for that item. Apps that have notifications turned off appear in the Not in Notification centre

Hi Ersin,
Exception 1 would seem to be FORMATTING_ERROR, which suggests something in the design of the Smartform. However, that doesn't fit with the form being generated from a report, but only erroring when called from a function module. I can think of no reason why the different calling method would be a factor.
When FORMATTING_ERROR is raise it should also set a message ID and number, are you able to determine what they are?

Nick

How can I manually refresh a Materialized View

Hi,
There's a materialized view created in 2006 as under:
CREATE MATERIALIZED VIEW "schema"."mv_name"
USING INDEX
REFRESH FAST ON DEMAND
WITH PRIMARY KEY USING DEFAULT LOCAL ROLLBACK SEGMENT
DISABLE QUERY REWRITE AS SELECT * FROM "table_name@dblink;
The problem is that the last refresh was done in Aug. I want to manually refresh this materialized view right now as there is a procedure based on this MV and its not showing the right data as the above materialized view has not been refreshed, so the data for this month is not showing.
Please let me know how I can refresh that MV right now.
Also do I need to change the refresh option. How can I change it so that the MV refreshes itself every second.
Thanks

Also do I need to change the refresh option. How can
I change it so that the MV refreshes itself every
second. Every second? Why do you want to do that?? Perhaps waht you really want is refresh the MV on commit.

do you know what is problem ?

Refresh of materialized views

Hi there,
i've got a question to the refreshment of materialized views: when updating or inserting / deleting data of some specific tables, my materialized view should be updated.
First of all, i though to make that happen by using triggers on the specific table and the DBMS_MVIEW.REFRESH() mechanism. But as i have read pretty often, it isn't recommended doing that with triggers.
But how can I get what I want :-)
Thank a lot for your answers,
Martin

Thanks for your answers,
the case with FAST REFRESH doesn't work. Our materialized are very complex and are using e.g subselect-statments, analytic functions,UNION, Order, Group by.... According to the documentation, we can't use the FAST REFRESH.
Using the REFRESH ON COMMIT could be possible. Having a look at the documentation, there is one interesting sentence: A REFRESH ON COMMIT materialized view is refreshed automatically when a transaction that does DML to one of the materialized view's detail tables commits
What are the materialized view's detail tables? Are that all tables in the FROM-Part of the query?

Is there any option for voting on a list item in SharePoint 2013?

Dear All,
I am looking for a feature vote a for list item from multiple users and need to show consolidated results on that.
for SharePoint 2013 we have "like", "rating" by using these can we show the consolidated results.
otherwise is there any alternative for this.
Thanks & Regards,
Jithendar

I haven't seen any OOB vote feature in sharepoint list. It's better to go with "like" or "ratting" options.

Are there any options for a company to host Buzzword internally?

My company currently produces documents using an HTML based editor (around a million docs a year/1500 employees). For a new project, we'd like a document solution that avoids some of the limitations we're currently dealing with. For example, we rely on IE custom print templates for printing headers/footers/boilerplate material. This is functional, but not ideal, and precludes full functionality in other browsers.
I like the Buzzword tech - with some tweaking I think it would meet our needs. However, with the nature of our business we'd need to store the documents locally and be able to control access, document creation and editing, etc.. on more of our own terms and in a strongly branded, tightly controlled environment.
Have you done arrangements like this before? Is there someone I can talk to in terms of pricing, etc..? Obviously I haven't done a ton of research at this point, but I figure someone here can point me in the right direction.
Thanks.
[email protected]

Hello,
Thank you for your post. Although this has come up before, we don't have any options to license Buzzword for in-house use. I would suggest posting this request to our Ideas site - http://ideas.acrobat.com. If it gets a lot of traction, it's something the product team would take a closer look at.

Any options for hyperthreading? Envy 17/i7

Hi,
    not sure which forum to post this in, but since we're talking about hardware level concurrency...
    are there any options configurable for hyperthreading on the envy 17 (3002ea)? Processor is an i7.
    I have an intensive application that I know for a fact won't benefit from additional logical cores (it only uses two threads), so I want to experiment a bit.
thanks

Hi Celeste,
Welcome to the HP Community Forum.
If you are running the computer on battery -- and you are leaving it alone for five minutes, you may actually want it to sleep. It uses far fewer resources to sleep than it does to stay active. Your system provides for "rapid wake up" and should respond soon after you open the lid when you again need it.
OK -- assuming you cannot wait even a few seconds! Smiling.
You might have missed a secondary setting that puts the notebook to sleep when it is running on battery. The notebook might be going to sleep sooner than you would like.
Control Panel > set icon view > Power Options > Change when the computer sleeps >
On Page: Change settings for the Plan
There are two main adjustments: On battery and Plugged in
You need to adjust the settings for the Display and for the amount of time the computer waits before it goes to sleep.
You can also adjust the brightness to save battery, that is, you can set the brightness to be a bit "less bright" when running on battery.

Fast Refresh in Materialized Views Partitioned

Hi all.. I've a little problem... let's go into it:
I have two tables:
A dimension table , named D1
A partitioned fact table, named F1
I create two materialized views log in each of 2 tables.
Ok.. Now, I created a Materialized View Partitioned, name MV_F1D1, with incremental refresh for it...
I can create the Materialized View Partitioned with fast refresh, no problem here...
First time Oracle make a Complete refresh, everything ok.. Then I make a
     BEGIN
          DBMS_SNAPSHOT.REFRESH('MV_F1D1','F');
     END;
And everything goes well...
But.. In my fact tables, I load the data with a temporary table, named F1_NP (Fact table no partitionated)
with the data of the current month. Every week I do this:
1) Load the data in F1_NP
2) If the LAST_PARTITION_MM_YYYY not exists in F1, I add the partition to F1...
3) ALTER TABLE F1 EXCHANGE PARTITION LAST_PARTITION_MM_YYYY WITH TABLE F1_NP
And, this is the problem....
After that process, the Log table of F1 is empty..
When i'm trying to fast refresh the mv_F1D1, I got an error
     ORA-12097 changes in the master tables during refresh, try refresh:
THis occurs when only I truncate a partition
in the fact table too.
Ok.. My only solution here is to make a complete refresh.. But I have only a new partition. I expected that with the PCT, Oracle let me
do it a fast refresh.
I'm looking for a solution in the web, and I installed the utlxmnv.sql:
1) Before add a partition in F1
truncate table mv_capabilities_table;
exec DBMS_MVIEW.EXPLAIN_MVIEW ( 'MV_F1D1' );
select * from mv_capabilities_table;
PCT Y
REFRESH_COMPLETE Y
REFRESH_FAST Y
REWRITE Y
PCT_TABLE Y F1
PCT_TABLE N D1 2068 Relation is not partitioned.
REFRESH_FAST_AFTER_INSERT Y
REFRESH_FAST_AFTER_ONETAB_DML Y
REFRESH_FAST_AFTER_ANY_DML Y
REFRESH_FAST_PCT Y
REWRITE_FULL_TEXT_MATCH Y
REWRITE_PARTIAL_TEXT_MATCH Y
REWRITE_GENERAL Y
REWRITE_PCT Y
PCT_TABLE_REWRITE Y F1
PCT_TABLE_REWRITE N D1 2068 Relation is not partitioned.
2) After truncate a partition in F1
truncate table mv_capabilities_table;
exec DBMS_MVIEW.EXPLAIN_MVIEW ( 'MV_F1D1');
select * from mv_capabilities_table;
PCT Y
REFRESH_COMPLETE Y
REFRESH_FAST Y
REWRITE Y
PCT_TABLE Y F1
PCT_TABLE N D1 2068 Relation is not partitioned.
REFRESH_FAST_AFTER_INSERT N F1 2077 Mv log is newer than last full refresh
REFRESH_FAST_AFTER_INSERT N F1 2077 Mv log is newer than last full refresh
REFRESH_FAST_AFTER_ONETAB_DML N 2146
REFRESH_FAST_AFTER_ANY_DML N F1 2076
REFRESH_FAST_AFTER_ANY_DML N 2161
REFRESH_FAST_PCT Y
REWRITE_FULL_TEXT_MATCH Y
REWRITE_PARTIAL_TEXT_MATCH Y
REWRITE_GENERAL Y
REWRITE_PCT Y
PCT_TABLE_REWRITE Y F1
PCT_TABLE_REWRITE N D1 2068 Relation is not partitioned.
BEGIN
          DBMS_SNAPSHOT.REFRESH('MV_F1D1','F');
END;
ORA-32313: REFRESH FAST of "MV_F1D1" unsupported after PMOPs
any ideas? Can I fast refresh a MV partitioned (composed with a Table Dimension and Fact table)
with PCT when I add data in the Dimension Table/add a partition in a Fact Table Partitioned?

Look at ATOMIC_REFRESH option, if you set this to FALSE you may see performance gain as it'll use DIRECT PATH and TRUNCATE. Data will be unavailable while being refreshed though.
