Reg: Buff v/s data Cache area Shared Sql
Hi Experts,I had a doubt about the Oracle architecture.
When a query is triggered, and then it checks whether the same is present in the area of SQL shared of the shared pool.
In addition, it is said That Database Buffer Cache stores recently used data blocks for faster recovery (of frequently used data).
Please correct me if I'm wrong.
Now, I get exactly the goal difference of two. Seems the same.
I read the articles of the Oracle documentation.
Pointers on this?
Thank you and best regards,

You answered you. The shared pool contains areas of memory that contain the sql code optimized for the treatment but not the data. The data for the same cursor will be available in the cache buffers data . Store the data in the buffer cache would reduce e physics / s for later execution and fetch the same data.

Private sql area shared sql areas
Hello, I read the link on the cache of the libraries below.
http://download.Oracle.com/docs/CD/B28359_01/server.111/b28318/memory.htm#i11734
Oracle shared sql and sql private shared pool areas. I understand the shared sql areas. But what is the use of private sql areas. It has the same info that we have shared sql areas.
Document says Oracle each user must have a separate copy of SQL area private. the statement on the private sql areas. They do not say something other than that... I don't know what oracle stores in private sql areas. Any help is appreciated.http://download.Oracle.com/docs/CD/B28359_01/server.111/b28318/memory.htm#i17716
The private SQL area contains data such as bind variable values, query execution state information, and query execution work areas. Each session that issues a SQL statement has a private SQL area. Each user that submits the same SQL statement has his or her own private SQL area that uses a single shared SQL area. Thus, many private SQL areas can be associated with the same shared SQL area.

Deletion of data that are shared with multiple clusters warehouses
Our ESX servers have initially setup by adding all the LUNS in three groups. Cluster 1, 2 and 3 all see the same disks.
We are redesigning our design and would like to delete unused data from the cluster 2 warehouses.
My question is, by deleting data warehouses in Group 2 will affect the data in cluster 1 or 3 warehouses?
Thank you!
Are you thinking of clicking on delete storage page? If so, Yes will delete the partition on this volume. Which will affect the volume and everything that uses it.
I went through a similar process last year. What I ended up doing removed access to the volumes of the servers that I didn't want more access and restart the hosts one by one. I think this is the way you want to go.
With ESX 3.5, I was unable to find a way to connect to the host on the volume. ESX 4 looks like it will be possible.

Hello
Our environment is Essbase 11.1.2.2 and work on Essbase EAS and components of Shared Services. One of our user tried to execute the Script of Cal of a single application and in the face of this error.
Dynamics Processor Calc does not reach more than [100] ESM blocks during the calculation, please increase the CalcLockBlock setting, and then try again (a small data cache setting can also cause this problem, check the size of data cache setting).
I did a few Google and found that we need to add something in the Essbase.cfg file as below.
Dynamics Processor Calc 1012704 fails to more blocks ESM number for the calculation, please increase the CalcLockBlock setting, and then try again (a small data cache setting can also cause this problem, check the size of data cache setting).
Possible problems
Analytical services cannot lock enough blocks to perform the calculation.
Possible solutions
Increase the number of blocks of analytical Services can allocate to a calculation:
- Set the maximum number of blocks of analytical Services can allocate at least 500.
- If you are not a
$ARBORPATH/bin/essbase.cfg
on the file server computer, create one using a text editor. - In the
essbase.cfg
folder on the server computer, set CALCLOCKBLOCKHIGH to 500. - Stopping and restarting Analysis server.
- If you are not a
- Add the command SET LOCKBLOCK STUDENT at the beginning of the calculation script.
- Set the cache of data large enough to hold all the blocks specified in the CALCLOCKBLOCKHIGH parameter.
In fact in our queue (essbase.cfg) Config Server we have given below added.
CalcLockBlockHigh 2000
CalcLockBlockDefault 200
CalcLockBlocklow 50
So my question is if edit us the file Essbase.cfg and add the above settings restart services will work? and if yes, why should change us the configuration file of server if the problem concerns a Cal Script application. Please guide me how to do this.
Kind regards
Naveen
Yes it must *.
Make sure that you have "migrated settings cache of database as well. If the cache is too small, you will have similar problems.
- Set the maximum number of blocks of analytical Services can allocate at least 500.

Thanks for posting on the Microsoft answers Forum. The first thing I would suggest running a virus scan. Make sure you have no virus causing problems. If you do not have an antivirus program, then you can download it free here: http://www.microsoft.com/Security_essentials/If there is no virus or it still does not work after virus cleaning, then start in safe mode and test from there. Here are the instructions for Safe Mode.

I'm a little surprised by the index cache data cache may not be transferable by any space until you do really something with the data of the cube (extract, load, calculate, etc.) but key cache seems to be filled immediately.

I have to stop and start the database after the data cache value increases?
Hello!
rule of Calc is in error and indicating that the error can be caused by data cache setting small size?
I increased the value, but it still gives the same error message. I can't stop and start the database, just clicked on apply.
I need also to check the journal rule and computation of the application to determine the cause of the error.
But the key is in the question in the header...
Kind regards

Yes, you do.

Dear,
I am facing a problem with the data cache. I increased the data cache. but it seems that there's something wrong with my business rule. In accordance with the following:
If you keep increasing the cache, but you still have this issue, it's time for you to think about your business rule or your design. Because more memory you allocate for the data cache, the more essbase RAM will succeed permanently (never released even the rule has already finished) unless you restart the app/Essbase cube
My question : is there away to restart the app/Essbase cube without restarting the Essbase Server? It makes no sense that whenever I have test the business rule, I need to do a reboot of the essbase server, if it does not work properly.
Thank you in advance!
Yes power of the database in environmental assessments, in Maxl look alter application and unloading/loading of database statements.

How to get data that are created the or before the last Wednesday
Hi, can someone please tell me how to write a query to retrieve the data that are created the or before last Wednesday.
Thanks in advance...
Hello
Here's one way:
WHERE created_date< next_day="" (="" trunc="" (sysdate="" )="" -="">
, "THURSDAY".
)
"Before Thursday' means the same as 'the or before Wednesday '.
This assumes that NLS_DATE_LANGUAGE is English. If you are not sure what is NLS_DATE_LANGUAGE, you can do this:
WHERE created_date< next_day="" (="" trunc="" (sysdate="" )="" -="">
, TO_CHAR (DATE ' 2014-03-06' - or any Thursday)
, 'DAY '.
)
)
There is nothing magical about March 6, 2014; will do any Thursday. To_char will return the translation of 'Thursday' in all that is the current NLS_DATE_LANGIUAGE, and NEXT_DAY can use this value.

How can I check for dates that are the same for today.
If I have a bunch of dates in a datetime colum. How can I check for dates that are the same for today.
"For example, this value of days would be ' #dateFormat (now (),"mm dd yyyy") #
The best I could come up with was:
Select * from data where data.userID =
2635 AND
"Convert (varchar, dateAdded, 101) = ' #dateFormat (now (),"mm dd yyyy") #
How can I get this to work smart peeople :)It is best to make the comparison on the datetime values. One technique is to get the current date at midnight. Then add one day to get tomorrow's date. In your sql query finds all values is greater than or equal to today and less than tomorrow.
One solution is to do everything in MS SQL
WHERE the dateAdded > = convert (datetime, convert (varchar, getdate(), 112), 112)
AND dateAdded = dateAdd (d, 1, convert (datetime, convert (varchar, getdate(), 112), 112))Another option could be to use CF to calculate dates:
WHERE the dateAdded > =.
AND dateAdded<>
