11.2.0.2 on Solaris..I have such a large post on a very basic space calculation.
We have several tablespaces starting with WLMCS in our DB..I just wanted to calculate the total space consumed in the disk by all these tablespace combined .When I queried DBA_DATA_FILES.MAXBYTES and DBA_DATA_FILES.USER_BYTES , I've noticed that ,
When AUTOEXTEND is NO: MAXBYTES is 0 for these datafiles . But USER_BYTES won't be 0 for these files
When AUTOEXTEND is YES: MAXBYTES will be a non-zero value for these datafiles . USER_BYTES won't be 0 either for these files-- Not including datafile names for better readability.
SYS > select tablespace_name, maxbytes/1024/1024, user_bytes/1024/1024, autoextensible from dba_data_files where tablespace_name like 'WLMCS%';
11 rows selected.To calculate the space consumed , I made 2 assumptions.Are the below 2 assumptions right?
Assumption 1. Whenever MAXBYTES = 0 , USER_BYTES should be considered for the space calculation.
Assumption 2. Whenever you have non-zero values for both MAXBYTES and USER_BYTES , MAXBYTES should be considered for the space calcuation.I did the calculation (adding up of) based on the above assumptions. Is this calcualtion Correct ?
-- Not including datafile names for better readability.
if we update partition key, internally row movement is done as if you had in fact deleted the row and reinserted it. It will update every single index on this table, and delete the old entry and insert a new one. It will do the physical work of a DELETE plus an INSERT. However, it is considered an update by Oracle even though it physically deletes and inserts the row¿therefore, it won't cause INSERT and DELETE triggers to fire, just the UPDATE triggers. Additionally, child tables that might prevent a DELETE due to a foreign key constraint won¿t. You do have to be prepared, however, for the extra work that will be performed; it is much more expensive than a normal UPDATE.
In above I inserted few rows into table and those belong to partition P1 and Tablespace DJB and then I updated partition key from A to B which resulted row movement from partition P1 to P2 which belong to tablespace users. Before updation data has consumed some space in tablespace DJB and after update those records consumed some space in tablespace USERS. But in this scenario I checked that space consumed in DJB is not released. Is there any way to get this space released ?
I am trying to create a function that when called will add the salary and commission a certain way to return an employee's annual salary.Here's my code
create or replace function Get_Annual_Comp (Sal in number, Commission in number) return number as [code]...
When I run the query, I get the proper rows return; however, my function does no calculation. If I input random numbers, I get the proper value returned. What I want is for my function to return the salary and commission of the employee specified in my select's where clause to be calculated as an annual salary.
I am using the below sql query to calculate working hours. The problem which i am facing is that query is taking lot of time to calculate the working hours. reduce the execution time of this query or if there is any other way to calculate working hours
The following query take 63.499 sec
SELECT sql_calc_found_rows gstime, MAX(stoptime) AS mx, MIN(starttime) AS mn,
Basically what I want is that I need to get desired result in such a way that, whenever Transaction type is Sales Order Issue, I want last TRANSACTION_COSTED_DATE of 'Intransit Shipment'
INVENTORY_ITEM_ID TRANSACTION_COSTED_DATE TRANSACTION_TYPE R 123 28-06-2012 21:36 Intransit Shipment 123 23-07-2012 01:25 Sales order issue 28-06-2012 21:36 123 30-07-2012 05:20 Sales order issue 28-06-2012 21:36
[Code]...
Lag with offset 1 doesn’t work as it will only go to previous row, What I want is that it should go to row above where transaction type is Intransit Shipment
A function should accept two parameters: from_date and to_date which returns no.of Saturdays and Sundays between these dates and also show the dates of those weekends.
I am trying to find sum for one record for each partition but while taking that timestamp giving me bit trouble, i have tried to reproduce the table and some little data
CREATE TABLE TEST_COUNT (END_TIME DATE ,SUCCESSFUL_ROWS NUMBER ,FAILED_ROWS NUMBER ,TBL_NAME VARCHAR (4) ,PARTITION_NAME VARCHAR (240) )
I have to create the following table. The fields Trend_Date, Price and Trend are already given. I have to calculate the field permanently and to insert the value in this permanent table.
Fields:
The field price belong to the value of a product during the trade. The field trade_date belongs to the moment of the trade. The field trend belongs to the future behavior of the the price. Here, the price of the present moment is compared to the following price (possible characteristics: 'UP', 'DOWN', 'STABLE'). The field permanently belongs to the time (in seconds) how long the value of the field Trend_Date (depending on the price) is still true.
For example:
Row 1: The trend in row 1 is 'UP' and it has a price of '11'. Until row 3 this remains true (the price is greater or equal to 11). In this case, the difference between row 1 and row 3 are 9801 (rounded) seconds.
Row 2: The trend in row 2 is 'DOWN' and it has a price of '12'. This remains true till to the end (the price is never greater than 12) In this case, the difference between row 2 and row 11 are 97346 (rounded) seconds. To calculate the 97346 seconds the field has to consider that between row 2 and row 11 are two days. There will be no trade between 18:00 and 07:00 o'clock. This belongs to 7 hours for each days, in seconds (2*46800) 93600. -> 190945-93600 = 97346s
Row 6: The trend in row 6 is 'UP' and it has a price of '5'. This remains true till to the end (the price is never smaller than 5) In this case, the difference between row 6 and row 11 are 65729 (rounded) seconds. To calculate the 65729 seconds the field has to consider that between row 65729 and row 11 are one days. There will be no trade between 18:00 and 07:00 o'clock. This belongs to 7 hours for each days, in seconds (1*46800) 46800. -> 112528-46800 = 65729s
Row 9: The trend in row 9 is 'STABLE' and it has a price of '8'. Until row 10 this remains true (the price is equal to 8 ). In this case, the difference between row 9 and row 10 is 14418 (rounded) seconds.
Row 11: Is empty because there are no values to compare.
CREATE TABLE "ALLOCATEASSOCIATES" ( "PROJID" VARCHAR2(30) NOT NULL ENABLE, "ASSOCIATEID" NUMBER(*,0) NOT NULL ENABLE, "ALLOCATIONSTARTDATE" DATE, "ALLOCATIONPERCENT" NUMBER(*,0),
[code]...
Given that 1. An associate must be allocated to at-least and a maximum of 100% at any given point of time 2. User selects 2 dates between which inconsistency of allocation needs to be displayed
If the end user selects 1st Apr 2012 and July 31st 2012 between which reports needs to be generated, am looking for the following output
The Allocation_Inconsistency denotes that the associate has a deficit of allocation between the 2 dates. The associate with ID 2 has a deficit of 75% of allocation from 1st Apr 2012 till 15th Apr 2012. Similarly 25% deficit between 16th Apr 2012 and 15th June 2012 and so on so forth. However, there is no allocation deficit for the month of July as he is allocated 100% for this month and hence is not appearing in the expected output.
I have a large table and want to calculate just a few values. Therefore, I don't want to create a new table, I want to update the table. Here an example:
I want to calculate the VALUE_LAG with ID = 4 only (-> two values).
create table zTEST ( PRODUCT number, ID number, VALUE number, VALUE_L1 number );
[Code]..
I tried this, but obviously, windows functions are not allowed in the update statement.
update zTEST set VALUE_L1 = lag(VALUE) over (partition by PRODUCT, order by ID) where ID = 4
Does it work with copying datafiles from 10g2 to 11g2? I want to move one huge tablespace (which contains one table) from 10g2 to 11g2, what is the best method to do that?
Basically , we have a large index tablespace , whose data files already spans multiple mount points , and has been extended with a new data file on a wrong mount point by mistake , Can we relocate this last datafile extension , to a different mount point while the DB is online ? Is there any special consideration for index datafiles (If such classification is correct ) or is it just like any other Oracle non-system datafile ?
What will be the effect on the normal data tables which are using this index if they are being accessed during the exercise? This is a 2 node Oracle 9i 9.2.0.8.0 RAC on Veritas Cluster .
I am looking for a way to monitor the creation of new datafiles / tempfiles.Let's say I am creating a new datafile of 8GB in size, and it takes a few minutes to create.
I have looked at v$session_longops, and several other system views, but cannot find any that indicate how the file creation is progressing.
I want to be able to display something simple, such as "72% complete".
Due to improper documentations of a certain project, I need to drop a DEFAULT tablespace of a newly created instance including it's associated datafiles by using this command:
"DROP TABLESPACE <tablespace name> INCLUDING CONTENTS AND DATAFILES;"
The default tablespace name is QWER (qwer01.dbf) and I added 2 datafiles in it, re: OPD_SML01.dbf & EXYT_SML01.dbf.
Can we restore a database if we have only the datafiles available? The database has been dropped but we have just the datafiles with NO system, sysaux,users and undo datafiles that were saved after taking the database offline and then dropping the database. I know this is strange but if possible, I want to see if we can retrieve some of the data from those datafiles to another database. BTW, There is no backup available for this database except the dbf files on OS.
when i install oraclexe on my system..when i want to connect the oraclexe then it give error

when i check this path D:oraclexeoradataXE then i check datafiles not generated in this folder
Just noticed MR(media recovery lock ) in our database,further check showd all datafiles had this lock since our database was shutdown abortly but was startup gracefully.
What is best practice to change small disk D:? I am beginner with Oracle. 10g on W2008. 5 datafiles (all indexes,second data file, 2 undotabs)*.dbf (34;30;1;34;12 GB) is on D:. Part of tablespaces (1 data, 1 undo)has files on c:.
I. 1.Shutdown 2008 server. 2.Copy D: image with GHOST to USB, network. 3.Connect new D, create RAID. 4.Restore image to D. 5.Start 2008 server.
II. 1.Stop application. 2.CONNECT AS SYSDBA 3.SHUTDOWN NORMAL or (IMMEDIATE)? 4.Copy files *.dbf at OS level from d: to ... USB disk, network. 5.Shutdown 2008 server. 6.Change disks, create RAID in BIOS. 7.Start W2008. Is Oracle at this moment in SHUTDOWN mode? 8.Copy back *.dbf to new D: (with directory structure). 9.STARTUP Oracle.
I need a PL/SQL stored procedure which will accept a datafile name as parameter and dynamically create and execute "alter tablespace" command to add this passed datafile dynamically.
Table D-7 shows a hierarchical file mapping of a sample OFA-compliant installation with two Oracle home directories and two databases. The database files are distributed across three mount points, /u02, /u03, and /u04. URL....
why three mount points (/u02, /u03, and /u04) for datafiles? don' understant this. isn't it better to store all datafiles in one mountpoint?
I am using 11.2.0.1 database and I have all my datafiles,control files,redo logs in /home/oracle/oradata and i would like to completely move all the files to /data/oradata folder.
What is the best method? (without losing old backup's , without reset log , no new incarnation,no new DBID) can it be done online /offline?
Is it recreating control file with new location and open database without resetlog the best method?
