Will reorg of tables and reindex of indexes help ? And How?

Suddenly users told that one of their applications has become very slow. They identified millions of history data also, which they deleted . But still it did not help. Should we go for reorg of tables and reindex of indexes? Will this at all help ? Will this help to gain space ? or It will help in speed ? How should I do it ?
Reorg tables
1. First take export dmp of all the tables of that particular schema.
2. Then truncate the tables.
3. Then import that export backup.
reindex indexes
1. Find out how much space is used by the indexes.
2. Add that much of space in a different tablespace
3. then move the indexes there.
I am not sure about the steps which I missed. I need some advice from you.
And how can I gain the space in the Unix server after this delete operation?

With problems like this, I think that the first response should not be that we need to reorg tables/indexes. Steps are as follows.
1)Ask users what portion of app is running slow? and how much slow.
2)Also as others have suggested generate awr report or statspack or estat/bstat and see where time is being spent?
3)Problem could be that execution plan of some sqls may have changed and they may be performing badly. This is the most likely reason. Other problem could be that there is some other contention in database or there is an I/O problem. All these you can find from these reports.

What is Relationship table and how to work on that

Hi MDM Gurus,
Can anybody please let me know regarding Relationships table and how to work with that. I am aware of all the other MDM concepts.
Regards
Yugandher

Hi,
Relationship tells how the records from main table and subtable are related to each other. We need to first create the entry in relationship table from MDM Console. MDM support two types of relationships:
1. Parent/Child Relationship - Applicable for all possibilities of main and lookup table
2. Sibling Relationship - Applicable only for Main table records
For More information refer the below links

Contacts are designed to be synced to a supported application on the computer or a cloud service.
Pictures taken with the device are designed to regularly be copied off the device to a computer as would be done with any digital camera.
If you have failed to use the device as designed it may be too late to recovery anything.
Is the device regularly backed up to a computer via iTunes? If so, the most recent backup (when restored to a replacement iOS device) should contain all contacts and pictures as of when the backup was created.

Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIs and corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 15 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

EAV modelling approach on database tables and how to use it in Forms Dvl

Hello,
I am dealing with two tables in data modell which are structured on EAV ( Entity-Attribute-Value ) modelling approach.
Survey( Survey# number not null,
Start_Date_Of_Survey date not null ,
End_Date_Of_Survey date null,
Sts_Of_Survey varchar2( 4 ) not null ,
Contractor_Partner# number not null, -- reference foreign key, to Partner's Table
Survey_Report CLOB ) ;
Survey# primary key of Survey.
Meta_Survey_Parameter_Register( Parameter# varchar2( 40 ) not null,
Additional_Parameter_Desc varchar2( 240 ) null,
Type_Of_Value varchar2( 60 ) not null,
Data_Type varchar2( 10 ) not null,
Unit varchar2( 10 ) null,
High_Value varchar2( 20 ) null,
Low_Value varchar2( 20 ) null );
Type_Of_Value Is restricted to : ATOMIC_VALUE, INTERVAL_VALUE_FROM_TO
Data_Type is restricted to: Date, time, number( X,Y ), varchar2,
Unit is varchar2 value not resstricted: for example: %, kg as kilo, m as meter, m/s as meter per second, null
This table is meta table so it suppose to be used as some register - static part of the schema.
Then I have table which attaches Parameters to the Survey as the association table
Survey_Parameters( Survey#, Parameter#, Value, Comment );
Primary key( Survey#, Parameter# );
I need to implement this in Forms and Reports.
My question is how to implement it to maximally make good use of Oracle forms 10g or 11g features and Oracle Reports 10g:
a) when fulfilling the survey and use of parsing rules supplied in Meta_Survey_Parameter_Register
b) at the producing as the survey report with reports
c) in data analyisis in data warehouse impementations.

Hello Craig,
Thank you Craig for your answer.
I must confess that I am also not familiar with EAV theoretical background and concept. Till recently I even did not know that this kind of problem could be placed
in theoretical background called EAV. This put smile nad releive on my mind. Because since this moment I do not feel this kind of problem as some exception or
some exceptional tools or data design ( object modelling and object databases ) suppose to be used. This way I can still counted on concepts in RDBMS databases
and applications. Well I guess so.
Let me comment and answer on your text between your lines.
I am only conceptually familiar with EAV modeling, so I don't claim to be an expert! ;-) Given the abstract way in which data is stored with EAV, I would suggest that you first create a SQL Query that will produce the desired record set.
Ok. But I guess you have in mind to transform vertical set of values to horizontal ( pivoting, transposing )?
View has cast operator that transform data type of each parameter from general ( e.g. varchar2 ) to the one that is registered in the
Meta_Parameter_Register. This way it is provided to get the survey with the list of assigned parameters in horizontal shape?
Once you have this, you can either use the Query as the source of a Database View and then base your Forms data block on this view or you can use the query in a Procedure and base your Forms data block on the procedure or lastely, you could use the query directly and base your Forms data block on the query using the "From Clause" option.
Ok, I think I understand it.
So When I have horizontal list there is challenge during
- insert
- delete
- update
operations how to handle these operations to transform to vertical operation.
This could only be done with Forms data block based on procedure and instead of triggers?
The simplest option would be to create a DB view and base your block on the view. You will not be able to update the data however. If you need to be able to change or add new data, I would suggest you use a Procedure based block. Take a look at these links for additional information on using Procedure and From Clause based blocks.
Ok Craig, sounds like it makes sense.
IT seems your suggestion is caling for some simpler example with the same characteristic of the problem.
Like two tables:
Master( Master#, ..... )
Detail( Master#, Detail#, value_low_or_just_value, value_high, data_type )
Forms: How to base a block on a FROM clause Query
Forms: How to base a data block on a Procedure
Ok,
Hope this helps,
I see your point and it makes sense , it is only the challenge to see how much of flexibility I can reach and how cheap workarounds are to preserve
the level of flexibility in the tools that are not naturally supporting EAV ( like forms and reports ).
If someone's response is helpful or correct, please mark it accordingly.
Sure...
We are on the line.
I am sure there is someone else in the community that experienced this kind of challenge.

How far will the extreme reach and how many users can be on there at the same time?

How far will the airport extreme reach and how many users can be on there at the same time?

Last question first, since that is the easy one......approximately 50 (fifty) users for wireless depending on how active each user might be.
The first question is much more difficult, as distance is not really the issue with wireless.....obstructions are the issue.
A wireless signal can easily travel 300 feet or more with no obstructions in the signal path.
But, a typical wall of sheetrock or wallboard in a home will absorb....on average....15-20% of the wireless signal. Brick or adobe will obviously absorb much more. A ceiling....because it is thicker....will absorb about 25-35% of the signal.
So, if the wireless signal must pass through several walls and a ceiling, there won't be much, if any, of the signal left....even though the distance that the signal travels is not great...for example, 20-25 feet.
Other wireless networks around you at the neighbors can also affect the relative strength of the wireless signal.
The bottom line....locate the AirPort Extreme where wireless devices will receive a signal with the least amount of obstructions in the signal path. Your actual performance cannot be predicted in advance. You will not know how well the AirPort Extreme works for you until you try it out in your home.
If you find that the signal does not reach as far as needed, you will need to add additional "extenders", like an AirPort Express to provide more signal coverage.

I want to know how much would it cost, and how would I purchase the Adobe cs6 softwares (from a store or online)?
I prefer to have the actual CD/DVD of the adobe cs6 bundle, would that be possible?
or do you have to download it online and get the serial number online too?
Thank you

Newbie: What UIcomponents are required to create my table and how?

Hi,
** Not the CODE, I just want roughly what components need and how is the mechanism in JSF.**
Sorry, I really have no idea.
Meal Option: Beef, Chicken, Fish
| Name | Morning | Lunch | Dinner |
| Peter | | | |
| Mary | | | |
I want to write a table, if Peter login, he can select which one of meal option he want to eat in every meal. But he cannot select the options for Mary, and others rows/selections are fade. And other people can add themselves in the table.
Using UISelectOne seems ugly. Do I have other option?
How to fade the selection?
Where can I get some calendar component? So that people can select specific date.

I am not sure about the functional requirement, but I can at least tell that you can use either h:dataTable or h:panelGrid for a tabular display.
About the calendar component, at least Tomahawk and RichFaces have one.

What is access sequence tables and how to use them in program?

hi all, I know a little about SD and access sequence tables, but I get a requriment like this:
condition type is a paramater
The condition types allowed in this report are: Note: A list of pre-defined condition types with their corresponding access sequence tables will be defined.
How can I make it? How can I use it in program to get the price?

Hi,
An access sequence is a search strategy with the aid of which the SAP
System searches for valid condition records of a certain condition type.
For example, you can stipulate for a price that the SAP System first
searches for a price for a specific plant, and then for a generally
applicable price.
For condition types for which you wish to maintain conditions with their
own validity period, you must assign an access sequence. With this, you
define which fields the SAP System checks in searching for a valid
condition record.
e.g. When you create condition record (e.g. Purchasing condition record) you enter condition type, system asks you the key combination to enter the entries. These key combinations are nothing but the access sequence. On the basis of combination of condition table it will search record. e.g. when u maintain condition record with acc seq Material/plant combination, it will transfer the same record in PO when u enter same material and plant in the PO.
Example:
An access sequence has been assigned to condition type PB00 so that
prices can be maintained in purchasing info records and contracts.
No access sequence has been assigned to condition type RC00 because it
does not have a validity period of its own. In the standard system, it is
always maintained simultaneously with the price and is valid for the
period of the price.

I need to get away from iphoto.   I use pixelmator for editing almost exclusively. I have a Sony disc hx200v camera and a Kodak.   I will need to know if my cameras (on mac) will be seamlessly supported and how to get all my existing photos safely to lig

I have several questions.   iPhoto does not meet my needs.    I would use lightroom mainly for organization and downloading photos from my camera cards.   My cameras are Sony disc-hx200v and a little Kodak I will need to know if they are fine with light room. Also I use pixelmator for photo editing and likely will use iskysoft dvd maker for mac to create my dvds once edited.      I am desperate to find a way to make my work flow work.   i.e.   I need to get photos somewhere on my mac, in this case it would be lightroom then I need to edit them in lightroom and pixelmator, then be able to get that album/slideshow/folder whatever you call it Into the dvd maker to voiceover and finish the project.      It looks like aperture would have been more to my taste but they are
also taking that away.   Yeah! Go Apple.   About all I will have left of use is an operating system and mail.     Will appreciate any help. I am 73 and doing dvd's for Amazon so I really can't afford any more programs that are snatched away and learning curves that change every 6 months.

Are you shooting in raw or jpeg?
I’m not sure there is raw support for your Sony model and you don’t say which Kodak you have. But for jpegs Lightroom will normally work.
For your existing photos it would usually be necessary to export versions to the desktop or create new folders in Finder. Those duplicates will contain the editing adjustments you have already made and can be imported into Lightroom using “Add” in the import dialog.
I would suggest you download Lightroom and use it free for 30 days. You can then test it to ensure it meets your needs. You can download from this link:
