Many storage spaces and data for each quarter of the year files
Hello
I am junior DBA and I have a question about tablespace partitioning or data file sharing.
I have a database of 10g in many storage spaces, for example:
KER_DATA_2009_Q1
KER_DATA_2009_Q2
KER_DATA_2009_Q3
KER_DATA_2009_Q4
KER_INDX_2009_Q1
KER_INDX_2009_Q2
KER_INDX_2009_Q3
KER_INDX_2009_Q4
There is also a data file for each tablespace that is mentioned.
But for this year 2013, only two big storage space I can get one and data KER_DATA, KER_INDX files.
All tables and indexes in the whole database are KER_DATA, KER_INDX, tablespaces.
I don't know any cut in two storage spaces and means of data files. Is this something like tablespace partitioning? This can be done automatically or someone needed to do it manually on the end of each quarter?
This should be done to improve performance, several small files data instead a large?
Can some admin explain this to me?
The reason for this separation of database/tablespace was partitioning. There are a lot of tables partitioned by date column, and there are partitions for each quarter of the year. There are tablespace with a data file for each quarter (partition).

You can use this:
with t as (select to_date ('01/01/2011', 'DD/MM/YYYY') start_date from dual) select date_calc from ( select start_date, (level-1)*7+trunc (start_date , 'D')+1 as date_calc from t connect by level <=53) where trunc(date_calc,'YYYY')=trunc(start_date,'YYYY') ;

How to calculate an average for each quarter in a year
Hello world
I have a table that stores all the unit tests for the data. I'm figuring avg unit tests that have been recorded by quarter in one year
I tried with avg and the meter, but I'm sure that the results returned are not perfect
Help me in this scenario.
Thank you
Sriksuser10699584 wrote:
so if there are 10 unit tests then the avg is 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10/10
It is a weird way to definig average. Anyway, why:
2005-2 Q 5 2.5
According to your package:
(1 + 2 + 3 + 4 + 5) / 5 = 3
not 2.5. I'll assume that it's a typo. Now based on Mathematics:
1 + 2 + 3 +... + n = (1 + n) * n / 2
The foregoing your 'average' would be:
(Count + 1 / 2)
Also, I suspect tc_vts column data type is DATE, if so:
select to_char(tc_vts,'YYYY-Q"Q"') "year-Quarter", count(*) "Total cases", (1 + count(*)) / 2 "Average of total cases" from Testcycl group by to_char(tc_vts,'YYYY-Q"Q"') order by "year-Quarter" /

Categories and labels for each folio give the possibility to the readers to make a selection
Hi, in my next app I need to assign a category to each folio that I will publish. The application will only contain specific articles and not have a big problem, the articles will be published in a single folio. The reader should be able to select the categories that interest and only the folio belonging to that categories should be displayed. For example, if a player select 'history', 'English' only folios that belong to this two categories appear. It is possible and if yes, how can I do? Thank you
You can try using the filters feature. Note that it is only available on the iPad: Digital Publishing Suite help | Creating filters in the library.

Please help with the oracle text and select for each word in the sentence
Hello
I have a problem with a query which NEEDS to be done in SQL (not pl/sql in the stored procedure):
Suppose that a phrase such as "Church of snowboarding."
Can I divide this by using:
Select regexp_substr ('church snowboard', ' [^] +', 1, level) word
of the double
connect regexp_substr ('church snowboard', ' [^] +', 1, level) is not NULL)
now I have words 'showboard' and 'Church '.
So far so good.
Now I need for each of these words, to create a list of unique IDS collected using text oracle contains the query as follows: (pseudocode)
for SPLIT.word in "snowboarding", "Church".
SELECT SCORE (1) NIVEAU_RECHERCHE,
NO_MATRC,
NO_NOM_
OF GR_OT_NOM_ASSJT
WHERE CONTAINS (name, SPLIT.word, 1) > 0
UNION
SELECT SCORE (1) NIVEAU_RECHERCHE,
NO_MATRC,
NO_NOM_
OF GR_OT_NOM_ASSJT
WHERE CONTAINS (name, ' SYN('||)) SPLIT.word: ', GR_THESAURUS)', 1) > 0
UNION
SELECT 100 AS NIVEAU_RECHERCHE,
NO_MATRC,
NO_NOM_
OF GR_OT_NOM_ASSJT
WHERE NAME LIKE '% "| SPLIT.word | '%'
so of course I have to untangle this UNION to remove duplicates
Anyone here sees a way out of my situation? A way to make the loop in a select (use with and such) then
Just add a select distinct NO_MATRC, NO_NOM_ from)
I tried, but I'm out of ideas so I thought that some guru here might have the answer ;)
Thanks in advance for any advice
See you soonYou might end up with something like the XML below, ideally as binding in the query.
SELECT SCORE (1) NIVEAU_RECHERCHE,
NO_MATRC,
NO_NOM_
OF GR_OT_NOM_ASSJT
WHERE CONTAINS (name, e (1) > 0
Church of snowboard
transform ((JETONS, "{", "}", "AND"))
transform ((JETONS, "{", "}", "OR"))
turn ((JETONS, «SYN (",", GR_THESAURUS) ', 'AND'))
turn ((JETONS, «SYN (",", GR_THESAURUS) ', 'GOLD'))
transform ((JETONS, «?)) {","} "," AND")) /seq >
transform ((JETONS, «?)) {","} "," GOLD")) /seq >

How to change the query to do this...?Ok. I looked more carefully at your sample and it looks like you are looking for:
SELECT RI.RESOURCE_NAME, TR.MSISDN, MAX(TR.ADDRESS1_GOOGLE) KEEP(DENSE_RANK LAST ORDER BY TR.MSG_DATE_INFO), MAX(TR.MSG_DATE_INFO) FROM TRACKING_REPORT TR, RESOURCE_INFO RI WHERE TR.MSISDN IN ( SELECT MSISDN FROM RESOURCE_INFO WHERE GROUP_ID ='1' AND COM_ID=2 ) AND RI.MSISDN = TR.MSISDN GROUP BY RI.RESOURCE_NAME, TR.MSISDN /

Hi Experts,
JDeveloper 12.1.3.0.0
I have a VO based on entity object. With a column of the VO is transient attribute (I created).
I need to call a stored procedure for each row in the transitional attribute and display the data in the form of af: table. As well as other attributes.
So can anyone suggest how can I achieve this?
Thank you
AR
I think that you need a stored function (which returns the value) in this case, is not?
Take a look at:
https://docs.Oracle.com/CD/B31017_01/Web.1013/b25947/bcadvgen005.htm
and search for:

WinSxS swallow all my server storage space and fill C:Drives causing unstable Windows
Hey there, I got a small cut of data center where we have virtualized 10. Which most is Server 2008 standard with 4 x x64Bit version.
I thought about creating a 75GB C partition would be more than enough space. After about 9 months of use of torque with a 64 bit OS and Exchange 2010, I was up to 5 GB space on my C drive. Fortunately, I had a load of spare to park my Exchange .edb files to remedy the problem of the lack of storage SAN.
What MS is going to deal with this problem. I'm lucky, I can just use extra storage space and make a difference. What of those who pay for hosted solutions / storage. This eventually cost them much more they may have planned to even if they copy actually that much data on the server.
Surely MS will come out as its eems to be a cleaning tool or a patch to stop this issue more and more out of control. Nobody seems to have a decent solution for this. Woe to anyone brave enough to just go and delete files to free up space.
Any ideas or advice greatly appreciated.
Looking forward to hear from you.
Glyn.

Please explain SVmotion (Storage Vmotion) and DRS for storage in simple words
Friends,
I little confusing... could you please contact Storage vmotion and DRS for storage in simple words and the important points to remember in this regard...
Kind regards
Sirot
9884106697
Storage DRS is a feature that you allow warehouses of data aggregated on a single object (cluster) and recommend the implementation of disks in virtual machine based on the performance of the store of data and the available space on the data store.
The DRS storage uses Storage vMotion to migrate virtual (online) computers from a data store to another to balance data store performance and space.
You can use Storage vMotion without storage DRS too, moving virtual machine between clusters of DRS storage and warehouses of data even from the local level to the data store shared.

Hello
I was wondering if I could get some information and opinions on the use of an array of type defined clusters to store configuration data. I am creating a program to test several EHR and wanted to have a control of type defined for each HAD with the information needed to create the DAQmx tasks for all signals for it must HAVE. I am eager to do so that the data are encoded in hard and not in a file that the user might spoil.
Controls of type def are then put into a Subvi who chooses as appropriate, one based on the enumeration of Type DUT connected to a case structure.
I have problems with the control of the defined type. I see issues when you try to save a configuration unique to each element of the array in the array of clusters. Somehow, it worked at first, but now by clicking on "Operations on the data--> default font of the current value ' on individual elements of the cluster or the entire cluster (array element) does not save data when I re - open the command def. What I am doing wrong? I'm trying to do something with the berries of the clusters that I shouldn't do?
I enclose one of the defined reference type controls. I tried to change it bare to see if that helped, but no luck.
To reproduce, change the resource string for the element 0 of the array and do the new value by default. Then close the def of type, and then reopen it. The old value is always present in this element. The VI is saved in LabVIEW 2012.
The values of a typedef are not proprigated to the instances of the control. They get if created WHEN data values have changed. They will be not updated with the changes to come. You must create a VI specifically to hardcode your values or to implement a file based initialization. The base file would be much better and more flexible. If you don't want users to change the data simply encryption. There is a wedding blowfish library that you can download.

I have copy of old tbird and seamonkey e-mail files with the files and emails for each. I need to add to new tbird install. can not find a way to do it. HELP PLEASE. previous e-mail files are under mail then mail.earthlink* .net and each of the five mail .net is an email address I have. I can't find a way to identify each file by email to the specific email address (IE mail.my E-mail name.net) so I can copy the files and emails from the past to the email addresses now under tbird. previous installed e-mail identities may not be the current configuration of e-mail files in tbird. I think that I must be sure that mail.name.net matches the previous mail.name.net to be able to copy and paste the old to the new. is there a way to find the file name correct the old email and correspond to the new? all my emails very important information are mostly in the old mail electronic id and must be available in the identification of email again (but same) how can I do this?

How to find the value max and min for each column in a table 2d?
For example, in the table max/min for the first three columns would be 45/23, 14/10, 80/67.
Thank you
Chuck,
With color on your bars, you should have enough experience to understand this.
You're a loop in the table already. Now you just need a function like table Max and min. loop. And you may need to transpose the table 2D.
