Storing DateTime to Table Storage - once UTC another time local

Weird stuff... Look at this TableEntity initialization:
Patient patient = new Patient
DateOfBirth = new DateTime(2009, 5, 15),
//DateOfBirth = DateTime.Today,
FirstName = "Alex",
LastName = "Bee",
Title = "Mr."
If I store this entity with DateTime(2009, 5, 15) to Table storage (using Storage Emulator) and then read it back the retrieved value is exactly the same. Now, if I uncomment the line with DateTime.Today the value I get is UTC (which is in my case 4 hours difference)!
So, ... WTF? :) What am I missing here?

Hi
That's true, for date times, we should always use UTC specially if there is load balancer involved or you are hosting the services in the cloud where you dont know which time zone the server will have..
So as a general practice use UTC dates all the time.

Oracle Table Storage Parameters - a nice reading

bold Gony's reading excercise for 07/09/2009 bold -
The below is from the web source http://www.praetoriate.com/t_%20tuning_storage_parameters.htm. Very good material.The notes refers to figures and diagrams which cannot be seen below. But the text below is ver useful.
Let’s begin this chapter by introducing the relationship between object storage parameters and performance. Poor object performance within Oracle is experienced in several areas:
Slow inserts Insert operations run slowly and have excessive I/O. This happens when blocks on the freelist only have room for a few rows before Oracle is forced to grab another free block.
Slow selects Select statements have excessive I/O because of chained rows. This occurs when rows “chain” and fragment onto several data blocks, causing additional I/O to fetch the blocks.
Slow updates Update statements run very slowly with double the amount of I/O. This happens when update operations expand a VARCHAR or BLOB column and Oracle is forced to chain the row contents onto additional data blocks.
Slow deletes Large delete statements can run slowly and cause segment header contention. This happens when rows are deleted and Oracle must relink the data block onto the freelist for the table.
As we see, the storage parameters for Oracle tables and indexes can have an important effect on the performance of the database. Let’s begin our discussion of object tuning by reviewing the common storage parameters that affect Oracle performance.
The pctfree Storage Parameter
The purpose of pctfree is to tell Oracle when to remove a block from the object’s freelist. Since the Oracle default is pctfree=10, blocks remain on the freelist while they are less than 90 percent full. As shown in Figure 10-5, once an insert makes the block grow beyond 90 percent full, it is removed from the freelist, leaving 10 percent of the block for row expansion. Furthermore, the data block will remain off the freelist even after the space drops below 90 percent. Only after subsequent delete operations cause the space to fall below the pctused threshold of 40 percent will Oracle put the block back onto the freelist.
Figure 10-83: The pctfree threshold
The pctused Storage Parameter
The pctused parameter tells Oracle when to add a previously full block onto the freelist. As rows are deleted from a table, the database blocks become eligible to accept new rows. This happens when the amount of space in a database block falls below pctused, and a freelist relink operation is triggered, as shown in Figure 10-6.
Figure 10-84: The pctused threshold
For example, with pctused=60, all database blocks that have less than 60 percent will be on the freelist, as well as other blocks that dropped below pctused and have not yet grown to pctfree. Once a block deletes a row and becomes less than 60 percent full, the block goes back on the freelist. When rows are deleted, data blocks become available when a block’s free space drops below the value of pctused for the table, and Oracle relinks the data block onto the freelist chain. As the table has rows inserted into it, it will grow until the space on the block exceeds the threshold pctfree, at which time the block is unlinked from the freelist.
The freelists Storage Parameter
The freelists parameter tells Oracle how many segment header blocks to create for a table or index. Multiple freelists are used to prevent segment header contention when several tasks compete to INSERT, UPDATE, or DELETE from the table. The freelists parameter should be set to the maximum number of concurrent update operations.
Prior to Oracle8i, you must reorganize the table to change the freelists storage parameter. In Oracle8i, you can dynamically add freelists to any table or index with the alter table command. In Oracle8i, adding a freelist reserves a new block in the table to hold the control structures. To use this feature, you must set the compatible parameter to 8.1.6 or greater.
The freelist groups Storage Parameter for OPS
The freelist groups parameter is used in Oracle Parallel Server (Real Application Clusters). When multiple instances access a table, separate freelist groups are allocated in the segment header. The freelist groups parameter should be set the number of instances that access the table. For details on segment internals with multiple freelist groups, see Chapter 13.
NOTE: The variables are called pctfree and pctused in the create table and alter table syntax, but they are called PCT_FREE and PCT_USED in the dba_tables view in the Oracle dictionary. The programmer responsible for this mix-up was promoted to senior vice president in recognition of his contribution to the complexity of the Oracle software.
Summary of Storage Parameter Rules
The following rules govern the settings for the storage parameters freelists, freelist groups, pctfree, and pctused. As you know, the value of pctused and pctfree can easily be changed at any time with the alter table command, and the observant DBA should be able to develop a methodology for deciding the optimal settings for these parameters. For now, accept these rules, and we will be discussing them in detail later in this chapter.
There is a direct trade-off between effective space utilization and high performance, and the table storage parameters control this trade-off:
For efficient space reuse A high value for pctused will effectively reuse space on data blocks, but at the expense of additional I/O. A high pctused means that relatively full blocks are placed on the freelist. Hence, these blocks will be able to accept only a few rows before becoming full again, leading to more I/O.
For high performance A low value for pctused means that Oracle will not place a data block onto the freelist until it is nearly empty. The block will be able to accept many rows until it becomes full, thereby reducing I/O at insert time. Remember that it is always faster for Oracle to extend into new blocks than to reuse existing blocks. It takes fewer resources for Oracle to extend a table than to manage freelists.
While we will go into the justification for these rules later in this chapter, let’s review the general guidelines for setting of object storage parameters:
Always set pctused to allow enough room to accept a new row. We never want to have a free block that does not have enough room to accept a row. If we do, this will cause a slowdown since Oracle will attempt to read five “dead” free blocks before extending the table to get an empty block.
The presence of chained rows in a table means that pctfree is too low or that db_block_size is too small. In most cases within Oracle, RAW and LONG RAW columns make huge rows that exceed the maximum block size for Oracle, making chained rows unavoidable.
If a table has simultaneous insert SQL processes, it needs to have simultaneous delete processes. Running a single purge job will place all of the free blocks on only one freelist, and none of the other freelists will contain any free blocks from the purge.
The freelist parameter should be set to the high-water mark of updates to a table. For example, if the customer table has up to 20 end users performing insert operations at any time, the customer table should have freelists=20.
The freelist groups parameter should be set the number of Real Application Clusters instances (Oracle Parallel Server in Oracle8i) that access the table.

How to fire "table change" once click other regions outside the table erea?

I have a JTable created with DefaultTableModel. Usually the edit behavior of table cell is like this:
1) Select one cell, it is highlighted in blue.
2) Double click the cell, it's made editable with white background.
3) Two scenarios
(a) Once finish edit, press "Enter", the cell background turns from white to blue. At the same time, the table change is "fired" .
(b) Once finish edit, click another cell, the originall cell turns white, and the new-clicked cell is highlighted in blue. At the same time, the table change is "fired".
4) While editing one cell, and click somewhere OUTSIDE the table area. In this case, the table change is NOT fired.
[This cause a confusion, user sees the changed text in table cell, but actually it is not stored and will not be stored in the table.]
So what I want to implement is: once click the region outside the table, the text in that editabe cell (where you are just editing) is stored and fired.
Can you help me? Thanks in advance!

sabre150 & other experts,
[see background in my first message]
User is still not completely satisfied with the current behavior, though "table changed" can be fired when clicking other controls(eg. buttons or checkboxes).
If I click a panel region(instead of a particular control), the "table changed" can not be fired. However, it is expected.
I guess the reason is:
a panel doesn't has a focus. so when clicking panel, the focus is not "lost" to the table cell.
Any hints?

How to read LONG RAW data from one table and insert into another table

Hello EVERYBODY
I have a table called sound with the following attributes. in the music attribute i have stored some messages in the different language like hindi, english etc. i want to concatinate all hindi messages and store in the another table with only one attribute of type LONG RAW.and this attribute is attached with the sound item.
when i click the play button of sound item the all the messages recorded in hindi will play one by one automatically. for that i'm doing the following.
i have written the following when button pressed trigger which will concatinate all the messages of any selected language from the sound table, and store in another table called temp.
and then sound will be played from the temp table.
declare
     tmp sound.music%type;
     temp1 sound.music%type;
     item_id ITEM;
cursor c1
is select music
from sound
where lang=:LIST10;
begin
     open c1;
     loop
          fetch c1 into tmp; //THIS LINE GENERATES THE ERROR
          temp1:=temp1||tmp;
          exit when c1%notfound;
     end loop;
CLOSE C1;
insert into temp values(temp1);
item_id:=Find_Item('Music');
go_item('music');
play_sound(item_id);
end;
but when i'm clicking the button it generates the following error.
WHEN-BUTTON-PRESSED TRIGGER RAISED UNHANDLED EXCEPTION ORA-06502.
ORA-06502: PL/SQL: numeric or value error
SQL> desc sound;
Name Null? Type
SL_NO NUMBER(2)
MUSIC LONG RAW
LANG CHAR(10)
IF MY PROCESS TO SOLVE THE ABOVE PROBLEM IS OK THEN PLESE TELL ME THE SOLUTION FOR THE ERROR. OTHER WISE PLEASE SUGGEST ME,IF ANY OTHER WAY IS THERE TO SOLVE THE ABOVE PROBLEM.
THANKS IN ADVANCE.

You can achieve this in many different ways, one is
1. Create another VO based on the EO which is based on the dest table.
2. At save, copy the contents of the source VO into the dest VO (see copy routine in dev guide).
3. commiting the transaction will push the data into the dest table on which the dest VO is based.
I understand that if we attach VO object instance to region/page, we only can pull and put data in to only one table.
if by table you mean a DB table, then no, you can have a VO based on multiple EOs which will do DMLs accordingly.Thanks

How to apply extra storage once purchased on iphone

how to apply extra storage once purchased on iphone

What you bought is extra iCloud storage, not storage space for your iPhone. It gives you more room for storing backups of the device, but won’t help in the process of updating it; for that, you need to delete content from the device and/or update it from iTunes on the computer.
iCloud storage space can’t be applied to an iPhone or other iOS device.

Stock transfer from storage bin to another storage bin.

Hi,
i would like to know the method to be followed in order to transfer the materials from one storage bin to another within the warehouse and also within a storage type.
Also i would like to know how to transfer the material from one storage type to another.

As everyone has mentioned above, to manually create TOs to transfer stock, use LT01 w/ movement type 999. However, this method is limited to a single material at a time.
Depending on your scenario, you may want to set up storage type replenishment - where you regularly restock a smaller warehouse location from a larger one:
Example: Small warehouse section with customer counter service & larger warehouse where bulk items and bulk quantities are stored
Not sure if this is your scenario or not, but here goes:
Requirement is to use the "Large, small" picking strategy for the receiving storage type.
Material master records in that storage type need minimum and control quantities maintained on the WH2 tab
Run (or schedule) program RLLNACH1 to automatically create transfer requirements to transfer stock from bulk storage to the smaller storage type - and then, depending on your config, either stop as TR or automatically post os TOs.
Good luck

Execute a VO '4' times and show the result in single table at once.

Hi,
I want to execute single a VO query multiple times with different parameters and show the results together in a Table at once
In Detail
I have a table to which is associated with a VO.
The VO contains SQL whose WhereClauseParameters need to be dynamically binded.say headerId and lineId
Select ... from ....where headerId = :1 AND lineId = :2
I have to pass these 4 values and show all the results in a single table
headerId lineid
H1 ............... L1
H1 ............... L2
H2 ............... L1
H2 ............... L2
I understand that i need to bind parameters dynamically and exceute the VO.
As i have 4 different set of parameters, the view object will be executed 4 times.
I want to show all the results together in a single table.
How can I do it.
thanks,
Gowtam

Hi Mani,
Thanks a lot for the patience and detailed solution.I will try it out and tell you the status.
Meanwhile, I have 2 questions on this solution(just curious)
I will give you the snapshot of the table
Table - ModelInfo
Model......Tube..... Float....Size......Col5.....Col6.......Col7.......
M1............T1.......... F1. .....1..........C15......C16.....C17.....
M1............T1...........F1.......2..........C25......C26.....C27.....
M1............T2......... .F2.......1..........C35......C36.....C37.....
M1............T2...........F2.......2..........C45......C46.....C47.....
M2............T1.......... F1. .....1..........
M2.............T1..........F1.....2.........Cn5.......Cn6........Cn7
.<continues...>
.<till>
.Mn............Tn..........Fn.......n........Cxy.......Cpq.......Crs....
Question 1:
if you notice this data,
The Columns 5 to 7 are dependent on Combination of Model,Tube,Float and Size.
Hence will this query work properly(without mixing up data from other Pk combination) and will it be efficient?(I Know this is a stupid qst, still double checking..As your solution assumes that each row is unique for Model only..which is not true)
Select ...From....Where
Model in(M1,M2,..Mn) AND Tube in(T1,T2..Tn) AND Float in(F1,F2,....Fn) and Size in(1,2...n).
In short, will C15,C16 and C17 appear only with M1,T1,F1,1..I believe it will.
Question 2:
As I told,
Third party program will return Array of Objects.
Each object will have a variable called Flow along with
Model,Tube,Float and Size.
Flow is not stored in the database(can not be stored due to functional reasons).I want to show this Flow also along with other columns fetched from the DB for all 100+ rows.
How can I do it?
I will give u the scenario(with just 2 rows)...please check(Flow is not stored in DB)
Third Party object : ObjModel
Model......Tube..... Float....Size......Flow
M1............T1.......... F1. .....1..........100
M1............T1...........F2.......2...........200.
M1............T2.......... F1.......1..........300
M1............T2...........F2.......2..........400
My concern is,
After the VO executes and shows other 6 columns, it should show Flow appropriately.(associated with each object in the array)
I understand that I need to have a Transient attribute in VO called[b] Flow.But I don't know how to perform the two tasks simultaneously..
Task1:Your solution on showing table columns
Task2:Showing Transient data for each object returned from program.
thanks,
Gowtam

How to change stored procedure with Table Valued Parameter

I am not sure how to change the normal stored procedure with Table Value Parameter.Do I have to create a separate Table or do I have to create a datatype. Can you please help me with this
ALTER PROCEDURE [dbo].[uspInsertorUpdateINF]
@dp_id char(32),
@dv_id char(32),
@em_number char(12),
@email varchar(50),
@emergency_relation char(32),
@option1 char(16),
@status char(20),
@em_id char(35),
@em_title varchar(64),
@date_hired datetime
AS
BEGIN
SET NOCOUNT ON;
MERGE [dbo].[em] AS [Targ]
USING (VALUES (@dp_id, @dv_id , @em_number, @email, @emergency_relation, @option1, @status, @em_id, @em_title, @date_hired))
AS [Sourc] (dp_id, dv_id, em_number, email, emergency_relation, option1, status, em_id, em_title, date_hired)
ON [Targ].em_id = [Sourc].em_id
WHEN MATCHED THEN
UPDATE
SET dp_id = [Sourc].dp_id,
dv_id = [Sourc].dv_id,
em_number = [Sourc].em_number,
email = [Sourc].email,
emergency_relation = [Sourc].emergency_relation,
option1 = [Sourc].option1,
status = [Sourc].status,
em_title = [Sourc].em_title,
date_hired = [Sourc].date_hired
WHEN NOT MATCHED BY TARGET THEN
INSERT (dp_id, dv_id, em_number, email, emergency_relation, option1, status, em_id, em_title,date_hired)
VALUES ([Sourc].dp_id, [Sourc].dv_id, [Sourc].em_number, [Sourc].email, [Sourc].emergency_relation, [Sourc].option1, [Sourc].status, [Sourc].em_id, [Sourc].em_title, [Sourc].date_hired);
END;

It's not clear how you would change the procedure. But assuming that you want to replace the existing scalar parameters with tabular input, this is how you would do it. You first create a table type:
CREATE TYPE Insertor_type AS TABLE
(dp_id char(32),
   dv_id char(32),
em_number char(12),
email varchar(50),
emergency_relation   char(32),
option1 char(16),
status    char(20),
em_id char(35),
em_title    varchar(64),
date_hired    datetime)
Then you change the procedure header:
ALTER PROCEDURE [dbo].[uspInsertorUpdateINF] @tvp Insertor_type READONLY AS
And finally you change the USING clause:
   USING (SELECT dp_id, dv_id , em_number, email, emergency_relation, option1, status, em_id, em_title, date_hired
FROM   @tvp) AS [Sourc] ON [Targ].em_id = [Sourc].em_id
The rest is fine as it is.

Azure table storage design for simple social networking

What is the best table design if I want to use Azure Table Service for a simple social networking website?
The website could have millions of users.
Users need to be able to view a list of all other users in the system sorted by the number of mutual connections.
Users must be able to view a list of their connections
User must be able to view content posted by themselves and their connections.
One major design constraint is that Azure table service queries are generally limited to the partition key and row key when there are a large number of records or else they get really slow. Another constraint is that query results are only sorted by the
partition key and then the row key.

For your scenario, I think making use of the SQL Azure makes more senses than usage of azure table storage service offering, nature of the data looks more relational in this particular context which is not recommended for table storage model design.
You can get started with SQL Azure at -

Is this the best design for asynchronous notifications (such as email)? Current design uses Web Site, Azure Service Bus Queue, Table Storage and Cloud Service Worker Role.

I am asking for feedback on this design. Here is an example user story:
As a group admin on the website I want to be notified when a user in my group uploads a file to the group.
Easiest solution would be that in the code handling the upload, we just directly create an email message in there and send it. However, this seems like it isn't really the appropriate level of separation of concerns, so instead we are thinking to have a separate
worker process which does nothing but send notifications. So, the website in the upload code handles receiving the file, extracting some metadata from it (like filename) and writing this to the database. As soon as it is done handling the file upload it then
does two things: Writes the details of the notification to be sent (such as subject, filename, etc...) to a dedicated "notification" table and also creates a message in a queue which the notification sending worker process monitors. The entire sequence
is shown in the diagram below.
My questions are: Do you see any drawbacks in this design? Is there a better design? The team wants to use Azure Worker Roles, Queues and Table storage. Is it the right call to use these components or is this design unnecessarily complex? Quality attribute
requirements are that it is easy to code, easy to maintain, easy to debug at runtime, auditable (history is available of when notifications were sent, etc...), monitor-able. Any other quality attributes you think we should be designing for?
More info:
We are creating a cloud application (in Azure) in which there are at least 2 components. The first is the "source" component (for example a UI / website) in which some action happens or some condition is met that triggers a second component or "worker"
to perform some job. These jobs have details or metadata associated with them which we plan to store in Azure Table Storage. Here is the pattern we are considering:
Steps:
Condition for job met.
Source writes job details to table.
Source puts job in queue.
Asynchronously:
Worker accepts job from queue.
Worker Records DateTimeStarted in table.
Queue marks job marked as "in progress".
Worker performs job.
Worker updates table with details (including DateTimeCompleted).
Worker reports completion to queue.
Job deleted from queue.
Please comment and let me know if I have this right, or if there is some better pattern. For example sake, consider the work to be "sending a notification" such as an email whose template fields are filled from the "details" mentioned in
the pattern.

Hi,
Thanks for your posting.
This development mode can exclude some errors, such as the file upload complete at the same time... from my experience, this is a good choice to achieve the goal.
Best Regards,
Jambor
