• bunch of table temporary organized vs table for organizing data

  We use the Oracle 10 g on Linux platform.
  
  We have an intermediate table where the data read from the file (containing 1 million rows per day) is loaded, enriched(insert/update/delete) and then finally load in the table of another. I want to know if this table is a global temporary table or normal heap organized to reduce the generation of undo/redo.
  
  I'm not in favor of the temporary table because:
  1. any additional pressure on the temporary tablespace can cause ORA-01652: unable to extend temp segment temporary problems
  2. they are mainly intended to manipulate specific session data.
  3 - statistics do not exist for these work Oracle tables. To do this, we will have to do a dynamic sampling in the query.
  
  The problem with the table organized in piles is that they generate more undo/redo as temporary tables.
  
  Please guide me.

  Some of you concerns can easily be mitigated.

  1 - temp tablespace

  A common practice for ETL processing to create and use a temporary tablespace customized to use TWG. This prevents the TWG of impacting on the standard temp space and possibly interfere with the rest of the DB.

  See "Creating a temporary Table" in the DBA Guide. This article has sample code that illustrates this.
  http://docs.Oracle.com/CD/B28359_01/server.111/b28310/tables003.htm#i1006400
  >
  By default, rows in a temporary table is stored in the temporary tablespace default of the user who creates it. However, you can assign a temporary table to a different tablespace when creating the temporary table by using the TABLESPACE in CREATE TABLE of TEMPORARY GLOBAL clause. You can use this feature to save the space used by temporary tables. For example, if you need to perform many operations of small temporary table and the default temporary tablespace is configured for sort operations and uses so a large measure, these small operations consume a lot of unnecessary disk space. In this case, it is best to assign a tablespace temporary second with a smaller measure.

  #2 (planned for the session-specific data processing) is correct, that they have the specific session data. But GTT can also be used simply to reduce the amount of REDO normal DML operations during the processing of data which are already isolated from other users and does not need to be shared.

  Sure - but a working Oracle generally does not collect statistics whenever you do DML on your staging table. And if you do stats new TRUNCATE/LOAD operations should gather anyway once you load the new data.

  You may not have considered one of the factors are that you should design your architecture to be scalable. It is quite possible that you have only a SINGLE step and your current treatment is very simple.

  If so AND you do not need an evolutionary process, so the solution suggested by knani, maybe the best solution for you. But this solution is not very scalable.

  Complext ETL implementations have several steps. And the data still does not move between these steps in one nice, easy step. It is a common requirement that after each stage of data processing can must be discussed or reported on make sure you that he satisfied all the requirements of the company. Then data problems (e.g. lack of data, incorrect, etc.) must be resolved before the data can be processed to the next step. Depending on the severity of the problems that step may need to be rerun.

  If only the TWG is used there is no way to "review" the data. And if ONLY the external tables are used, then you can not tables of several process efficient in parallel and asynchronously.

  Complex implementations that I worked on usually consisted of a range of external and normal tables and TWG.

  External tables and one step simple "data cleansing" are used to load data into tables normal as soon as possible. That allows multiple processes to run asynchronously and in parallel for the detection of problems of data 'stored' as much as possible. Any table can be reloaded/processed without affecting other processes.

  This suggests that your first step should knapen processes in place do the same "serial" cleaning possible.

  The second stage of ETL, when necessary, can perform cleanup of more complex data for data in a table or several tables. TWG can be effectively used here to store the intermediate results that may have large amounts of 'temporary' DML performed on the data. At the end of this stage the TWG data would be transferred to another table of result or permanent staging.

  Start with a simple one-step process (maybe Karthicks). The key is to avoid complicating the process in a way that makes it impassable.

• Table for the data to HAVE it

  Please add the table to my VI.

  Please see the attachment.

  A probe inside the loop shows a lot of activities.  Are you preventing the VI with the command menu to cancel the execution? If so, you will never see data outside the While loop. Data will only forward your While loop when you stop the loop by program.

  Your STOP button is hidden behind the chart. It out behind the loop and use it to stop the loop. Then you will see the table becomes populated.

  Your spreadsheet column headings indicates that you want to save the square and square root average of each sample. If this is the case, then these values must be calculated at the time of acquisition before the release of the data in the spreadsheet file.

• Fill a table with date values with a fixed increment

  Hello
  
  I want to fill a table with a date column with the increment of a fixed value date values. The start date is selectable, the increment is selectable and the number of records is adjustable as well.
  For example
  start date is 1905-Jan-02, 15:00 (DD-MON-YYYY, HH24:MI:SS)
  increment is 1 hour and 5 minutes
  None. records is 10
  then the dates in the table must be
  REC 1 1905 - Jan - 02, 15:00
  REC 2 1905 - Jan - 02, 16:05
  REC 3 1905 - Jan - 02, 17:10
  ....
  REC 9 1905 - Jan - 02, 23:40
  REC 10 1905 - Jan - 03, 00:45:00
  
  We are working on 11 GR 2, the number of records can be between a few hundred and a few million and they must be ordered with Crescent of time (maybe to have a whole id).
  Any ideas how to fill this table (simple and fast?) using sql / plsql are welcome.
  
  Thanks, Hannes

  Something along the lines of:

  SQL> alter session set nls_date_format = 'YYYY-Mon-DD HH24:MI:SS';
  
  Session altered.
  
  SQL> select trunc(sysdate,'HH')+((rownum-1)*(1/24)*(65/60)) as dt
    2  from dual connect by rownum <= 20;

• How can, during the collection of data, start a new column in my table every 100 data points?

  Hello! I have a problem with my data - I get in a wide range of 1 x 1000, but it's the repeated measures, each taking about 500 data points. I want to break this table for this data string start a new column in my table every 500 points given. I don't know how to do it-please help!

  Hey thanks for the sponsor and the first off I must apologize for the State, I am attaching my VI. I put the part of the VI that I am working on (my team has access, so didn't post everything here) and also attached the data file (when just written in a spreadsheet file, not through the attached VI). I want to convert the long row of data and then start a new column every 50, 100, 5 points (user-defined).

  Using the data from the file, you can reshape everything simply (as you already!), followed by transposition (since you want columns instead of rows). 2D arrays must always be rectangular, so the last column is filled with zeros if necessary. Is that what you want?

  

  Of course if you try to add a new column in a file, that will not work. You can only add lines in an existing file because of the way the data is organized. To add columns, the entire file must be read, intertwined and all re-written new data in the file.

• expdp for all dates earlier or equal to 31/03/2009

  I created a copy of my production for migration on different server. We have windows 2003 and oracle 10.2.0.4.I created a schema ivs2_prod (metadata_only) thru expdp/impdp and now want expdp/impdp some data tables for all dates prior to or equal to 31/03/2009 11:59:59.I don't see any option in this utility to do this. You gurus can help me with the solution for this.

  Deepa,

  Use the settings file instead of using the query on the command line option, if you want to use the query option on command that you escape ' \ ' to correctly format the query. Try this and it should work

  #mytest.par

  query="where collectiondate <= to_date('2009-03-31 11:59:59','YYYY-MM-DD HH24:MI:SS')"

  Concerning

• Date dimension unique creating aggregation tables

  Hi guys,.
  
  I have a date single dimension (D1 - D) with key as date_id and the granularity is at the level of the day. I did table(F1-D) that gives daily transactions. Now, I created three tables of aggregation with F2-M(aggregated to monthly), Q(Aggregated to quarterly)-F3, F4-Y(Aggregated to yearly). As I said. I have a table of unique date with date-id as a key dimension. I have other columns month, quarter, year in the Date dimension.
  
  
  My question is: is this single dimension table is sufficient to create the joins and maintain layer MDB. I joined the date_id of all facts in the physical layer. MDB layer, I have a fact and logical table 4 sources. II have created the hierarchy of the Date dimension dimension and created the logical levels as a year, quarter, month, and day and also set their respective level keys. Now, after doing this I also put the logic levels for logic table 4 sources in the fact table.
  
  Here, I get an error saying:
  
  
  
  WARNINGS:
  
  
  BUSINESS financial model MODEL:
  [39059] D04_DIM_DATE logical dimension table has a source of D04_DIM_DATE at the level of detail of D04_DIM_DATE that connects to a source of fact level superior F02_FACT_GL_DLY_TRAN_BAL. F03_FACT_GL_PERIOD_TRAN_BAL
  
  
  
  
  Can someone tell me why I get this error.

  Reverse - your group table months must have information on the year.

  It's so she can be summarized in the parent hierarchy levels.

  In general, it is so you don't have to create a table of aggregation for each situation - your table of months can be used for aggregates of the year. Still quite effective (12 times more data than the needs, but better than 365 times).

  Think about your particular situation where you have a year AND a month group you might get away without information from parent levels - but I have not tested this scenario.

  With the second part, let's say you have a description of months and a key of the month field. When you select month and income description, obiee needs to know where to find the description of months of. You don't find it secondary date for reasons mentioned previously dimension table. So, you tell him to do it from the global table. It is a simple as you drag the respective physical column from the overall table on the existing logical column for the description of months.

  Kind regards

• Date for date dimension pull upward (Dimension to Dimension)

  Need advice...
  
  1. I have a person dimension table and the sales fact table. Person_id is the foreign key in the fact. I want to be able to make the date of birth. But the size of the person has only dob_sid which should point to the dimension of the day to get my the equivalent date. That's the problem... I can't join dimension dimension of the day person, I need to be able to join by fact, but the fact table is absent from the dob_sid.
  2. the second question is, dimension of the person has other dates partners action_date, cancel_date, etc. in addition to a date field that I need to attach to the dimension of the day.
  
  How will I be able to do this in BMM? Physical layer?

  The key (no pun intended) is here to alias your date dimension for several searches to date, you need, these aliases directly join your dimension of person out the appropriate keys.

  Thank you.

  Download and run JDiskReport.

  There are a number of things you can do to- temporarily - free up disk space.  The only real solution, however, is to get a larger hard drive.

  • You can run Disk Cleanup (start > run > cleanmgr > OK)
  • You can reduce the size allocated for the restoration of the system to about 1 GB (right click on desktop > properties > system restore > settings)
  • You can disable hibernation (if you don't use it) (right click on an empty spot on the desktop > properties > screen saver > power > Hibernate)
  • You can disable the indexing of the drive, which will also speed up your computer a bit (http://lifehacker.com/031440/turn-off-indexing-and-speed-up-windows-xp)
  • You can reduce the size of your Internet browser cache (depending on the browser that you use)
  • You can remove most of the $NTUninstallKBxxxxxx files $ following the directions here: http://windowsxp.mvps.org/Hotfix_backup.htm (read the warnings in the gray box first)

  But none of these answers you will earn really large amounts of space for very long.  The term solution time is a bigger hard drive.

  In the meantime, download and run JDiskReport, that will show you graphically what files take up more space and seem to so indicate what files to delete or uninstall applications.

• Best practices for migrating data tables - please comment.

  I have 5 new tables stocked with data that must be promoted an evolution to a production environment.
  Instead of just DBA using a data migration tool, they are insistent that I have record and provide scripts for each commit, in good condition, necessary both to build the table and insert the data from ground zero.
  
  I'm very little used to such an environment, and it looks much more risky for me to try to reconstruct the objects from scratch, so I already have a model perfect, tested and ready.
  
  They require a lot of literature, where each step is recorded in a document and use for deployment.
  I think their purpose is that they do not want to rely on backups but would rather than rely on a document that specifies each step to recreate.
  
  Please comment on your view of this practice. Thank you!

  I'm not a DBA. I can't even hold a candle to the fans of the forum as Srini/Justin/sb.
  Now that I'm giving a slightly different opinion.

  It is great to have, and I paraphrase of various positions
  Deployment documents,
  sign off of groups
  recovery steps
  Source code control
  repositories
  "The production environment is sacred. All the risks that must be reduced to a minimum at any price. In my opinion a DBA should NEVER move anything from a development environment directly in a production environment. 'NEVER.'
  etc etc.

  But we cannot generalize that each production system must have these. Each customer is different; everyone has different levels of fault tolerance.

  You can't wait for a change of design of the product to a cabinetmaker to go through "as rigorous than at NASA. Why would it be different for software change?

  How rigorous you put is a bit subjective - it depends on the policies of the company, experiences in society with the disasters of migration (if any) and the corporate culture.

  OP can come from a customer with lax controls. And it can be questioned if the rigour at the level of the new customer is worth it.

  To a single client, (and I don't kid), the prod password is apps/apps. (after 12 years of being alive!) I was appalled at first. But it's a very small business. They got saddled with EBS during the .com boom Hay days. They use just 2 modules in EBS. If I speak of creation (and charge) these documents/processes, I would lose the customer.
  My point is that not all places must or want these controls. By trial and error, you get what is the best company.

  OP:
  You said that you're not used to this type of environment. I recommend that you go with the current first. Spend time on understanding the value/use/history of these processes. Ask if they still seem too much to you. Keep in mind: this is subjective. And if it comes down to your existing reviews of the v/s, you need either an authority OR some means of persuasion (money / sox (intentional typo here) / beheaded horse heads... everything that works!)

  Select 2 cid, 122 k' sub '123' catcode, of any double Union

  Select 2 cid, catcode '234i', '124' void in any union double

  Select 2 cid, 238 k' void '124' catcode, double

  )

  void)

  Select 1 cid, sub '123' of any union double

  Select 2 cid, sub '124' double

  )

  output must be

  CID listname flg topic catcode

  1       test            r                 123

  Basically, the user will pass a cid, in this case 1. I'll read the itemlist where cid = 1 and I want to join all the other tables

  to itemlist in such a way that I can generate extra lines.  If no entry is found for cid 1, for example, in category 1 or auxiliary table

  then the beloging column of this table must be null in the result

  can someone help me write a query to produce the output above

  Here is an explanation of the output.  a user will have a front screen where it can enter itemlist info.
  then in a submenu may enter a category or sub or both or none of them. the user can select multiple categories or sub
  When the user presses the button Save, an entry will be made in the itemlist table, for example the cid = 1.
  If he choose a category but without Subs, then will be entered into the table at say cid = 1

  
  but no entries will be made for sub because he chose not to all values.  If he chooses void instead of category values
  then sub taable will fill and category is not. If he chooses the category and under, then both will be filled.

  what I want to do is to join the itemlist with table category and sub table and get the data to the Scriptures, this intervention of the user.
  These entries not found will be the null value column in the result.
  for example, the cid = 1 itemlist, if user enter category but not void, itemlist will be the join with the table category and sub
  but since sub has no entry for the cid = 1, the column object will be empty in the output, but catcode will fill

  I'm so confused.

  It is a query (that is, just a SELECT statement, which shows the data already present in the tables), or is this a DML statement, that will add data to the tables?  If it's just a query, then do not say things like "entries will be taken" or "filled with tables.

  Assuming you want a request maybe you want something like this:

  WITH c_and_s AS

  (

  SELECT NVL (c.cid, s.cid) AS cid

  NVL (c.sub, s.sub) AS topic

  , NVL2 (s.cid, c.catcode, NULL) AS catcode

  CATEGORY 1 c

  FULL OUTER JOIN void s ON c.cid = s.cid

  AND c.sub = s.sub

  )

  SELECT i.cid, i.listname, i.flg

  cs.subject, cs.catcode

  Itemlist I have

  LEFT OUTER JOIN c_and_s ON cs.cid = i.cid cs

  WHERE the i.cid (1) - you can do the cids 2 or several at the same time, if you want to

  ORDER BY i.cid, cs.subject, cs.catcode

  ;

  This example gets the output you asked data sample you posted.

• There is 'table' for the object_type values?

  I wonder if there is a system view, or a table for all the values that can appear in the all_objects.object_type column? Or maybe the only way to get this list of os values to query with the distinct keyword dba_objects.object_type?

  Thank you
