• Question about parallel hint and 'alter table enable parallel DML'

  Hi all
  
  I have a DML as follows:
  
  Insert / * + append * / into table1
  Select *.
  of COMPLEX_VIEW;
  
  Here complex_view contains a very complicated SQL, in which there is some heavy tables joins, subqueries, and aggregations.
  
  Question 1:
  
  Let's assume that the underlying tables have no attribute "parallel." Where should I add "parallel index" to force it to be run in parallel and can get better performance?
  
  Some members think that what follows is good.
  
  Insert / * + append * / into table1
  Select / * + parallel (a 4) * / *.
  of COMPLEX_VIEW;
  
  But I think that indicators must be put in the defintion of the complex view where they should be and do not put advice to the main insert DML, like this:
  
  Insert / * + append * / into table1
  Select *.
  of COMPLEX_VIEW; -I added the indicators in the COMPLEX_VIEW.
  
  What is your opinion?
  
  Quesion2:
  Without ' alter session enable parallel DML ", I can see the parallel session in v$ px_session thus." And the execution time has been shortened. This proves without this statement, the DML is also run in parallel.
  
  So, what is the effect of this statement?
  
  Best regards
  Leon

  I prefer the suspicion out of the COMPLEX_VIEW. This way, only this application forces the suspicion. If you put the indicator in the COMPLEX_VIEW, any other query on COMPLEX_VIEW (or Assembly of COMPLEX_VIEW to another view or a table) would also "encode" indicator in its execution. You don't then isolation parallel query to only where it is needed.

  If you put the parallel indicator in SELECT it (or view), the query is parallelized. This does not necessarily mean that the INSERT is parallelized. What you see v$ px_session are only slaves to PQ to SELECT.
  You must ALTER SESSION ACTIVATE PARALLEL DML and add the PARALLEL indicator in the INSERT.

• Question about full scan of the Table and Tablespaces

  Good evening (or morning).
  
  I read the Concepts of Oracle (I am new to Oracle) and it seems that, based on the way in which Oracle allocates and manages the storage of the local the following is true:
  
  Principle: A table which is often accessible by using a full table scan (for some reason any) would be better resident in its own dedicated tablespace.
  
  The main reason I came to this conclusion is that when you perform a full table scan, Oracle doesn't diluvium IO, reading probably one step at a time. If datafile (s) of storage space only contain data for a single table, then a reading series will have to skip segments containing the data in the other tables (as is the case if the tablespace is shared with other tables). The performance improvement is probably low, but it seems that there is a very similarly.
  
  I wish I had the thoughts of DBA experienced about the assumption above.
  
  Thank you for your contribution,
  
  John.

  a reading series will not jump the segments that contain data from other tables

  You are referring to a misleading picture of the operation.

  Let's say 'A' table is a table among a number of tables in a tablespace that consists of one or more data files.
  Since this is one of the many tables, it may not start at the beginning of a data file. His first measure may be somewhere in the middle of the file. The next step may not be nearby with the first step. The 3rd degree can be in different data file.
  So, it's the picture where you see Oracle having to jump the other tables when you do a FullTableScan.

  Now, view the same image:
  Measure 1 is in the 1000 to the 1127 block block (IE 128 blocks) in the data file 6
  Measure 2 is the 2400 block 2527 block in the data file 6
  3 is to the block to block 9371 9245 in datafile 12

  How Oracle does not have a FullTableScan? It starts with the segment header to get a map of the extent (it would read UET$ in a dictionary managed tablespace). He knows now what degrees it should read.
  What is doing?

  He made a call to the operating system to read 1000 blocks Oracle 1127 in the data file 6.
  The operating system then translates this call to starts and ID ranges and the block of the file system.
  The operating system puts this request to the storage subsystem.
  The storage subsystem and then translated the BONE, ID, blockrange to the drive starts, track, sector.
  Assume that these are all the neighbor on the single disc (that is, the volume is not distributed over multiple LUNS and disks).
  Storage reads the information and sends it to the operating system. This can still mean multiple readings, because the head (or several heads because the disc is made up of several trays) does not read 1 MB in an "appeal".
  The operating system then collects the 1 MB and passes it to Oracle.
  Oracle then fills buffers in its cache buffers--(PS: Astuce!) Tip! (: don't you know that it will be not be neighbor memory locations?)
  Microseconds past milliseconds.
  The disc is still spinning (it stops ). It has "evolved" - a different set of blocks are now under the read head.

  Oracle is now asking the OS for blocks of 2400 to 2527 in the data file 6.
  Oracle did not to "jump the other tables. He just made a separate call to the OS with a new range of blocks.
  The operating system now translates the block ID and filenumber at its own mapping.
  Storage then made his translation.
  The disc under the head blocks are very (almost certain) to be a different from blocks together. Not even those corresponding to 1128 Oracle Oracle datafile block 6. Not even the ones corresponding to 2400 block Oracle in Oracle data files.
  We are suffering now fetch - and reading the disk.

  and the story continues...

  And what happens if there is finally another user on the same system? Between the first blocks 1000-1127 call and the second call to blocks 2400-2527, that other user requested blocks 2000 (IE made a call from reading one piece).
  And, after the second measure is read by the user FullTableScan, a third user has requested block 2048 in a single block read call.

  It is important that the Table is not in the neighbor extensions? Even if you did put the table in "adjacent areas" they are not likely to be contiguous on the disk. Even if they are nearby on the disk, they are not likely to be able to read without delay, because the disc has passed.
  And we have not even spoken interleaving where readings from multiple disks need to be coordinated.

  So why still prefer 1Mo diluvium readings in Oracle? Because most SOAs allow a single OS call of up to 1 MB. Therefore, the overhead of Oracle making a call to read 1 MB are experienced only once. If the operating system allowed a maximum of 256KB reads diluvium, even a reading of 1 MB measurement must be carried out as 4 separate calls to the OS (and, recursively, 4 separate calls to the OS for the storage subsystem). We try to reduce the number of calls from software that we do. We cannot reduce the time of access and reading (but allows us to achieve more high "parallelism" in readings striping).

  Hello

  The query you posted is the right idea. He made the inner joins, where lines are included in the game only if they appear in all the tables of results. There is nothing of Amy d1 and nothing on Pete in d2, so they are not included.
  Just change your query to make the outer joins, so that all students will be included or not, they have a game in d1, and whether or not they have a game in d2, like this:

  SELECT    s.name
  ,        s.id
  ,        d1.level_code          AS ug
  ,       d1.major          AS ug_major
  ,        d2.level_code          AS gr
  ,       d2.major          AS gr_major
  FROM             student    s
  LEFT OUTER JOIN  degree         d1  ON   d1.id         = s.id
                                   AND  d1.level_code  = 1
  LEFT OUTER JOIN  degree     d2  ON   d2.id         = s.id
                                   AND  d2.level_code  = 2
  ;
  

  Thanks for posting the CREATE TABLE and INSERT statements; It's very useful!
  You should always put your version of Oracle, too. He could not relevant in this case. The above query will work in Oracle 9 or higher.

• Question about the definition of a table null vs defining each element null in the table and the recording of memory.

  Hello

  I try to avoid any kind of memory leaks or problems of garbage collection.

• question about 'STRUCTURE to VALIDATE the TABLE ANALYZER' in 9i

  Hello
  I have a 9.2.0.8 database on AIX. After a copy of storage of my produztion datafiles from a site to another, I performed a DBV to ensure that all copies were correct. After that I started my db correctly.
  Now might be a good idea to perform a "ANALYZE TABLE tabname VALIDATE STRUCTURE;" statement on any table of my database to ensure that I don't have a corruption? Are there disadvantages of this operation?

  Hello
  You can "validate" it roughly following the steps:

  Start the instance and open the database.

  see the alert log for possible errors.

  check the status of the data files of dba_data_files
  check the status of all storage spaces
  Check for invalid procedures, functions, or triggers and recompile them.
  Check the statistics and you can collect the again.

  If everything is good, so well done and hope for the best.

• Philosophical question about the design of the table

  I'm new in the world of RDBMS. I read a lot but have little practical experience. I'm upgrading of old applications that I know well. I'm interested in advice/opinions on a number of issues, from it.
  
  My application periodically (at the discretion of the user, so can be daily, weekly or monthly) should take a snapshot of some data. This snapshot is then used for various activities, such as a control point of reconciliation with external clients - so it must be 'frozen' rather than be derived at a later date. But if the snapshot proved to be a mistake, I can possibly be rerun (crushed) - requiring all lines to delete everything first.
  
  Data must be accessible in different ways, everything would need the date of snapshot to be part of the index or a group of clauses.
  
  Snapshots can be copied or replicated to other servers for purposes to relieve the burden of filing database. Old clichés may be archived, ignored backups of routine, deleted and so on.
  
  Is there a case for the inclusion of the date of snapshot as part of the name of the table? It would simplify the index structures, reduce the size of the individual table, perhaps to improve the competition (for users who access an old cliché while another is being created), facilitate separate archiving and much easier to drop and create table to remove all the lines before a replay. Of course, it reduces the size of the table that could potentially become very large.
  
  However, the previous snapshot is used as a starting point for the following, or a subsequent repeat) you need to be able to quickly determine who is the nearest date start - easy if they are all in 1 table, can be more load trying to determine is whether a specific table at the time to a given date.
  
  I look forward to some expert advice. :)

  No--not from a point of view of the data modeling. The snapshot date is an attribute. Attributes are not incorporated in the name of the entity being modeled.

  However, you can decide to implement the instant entity tabular instant daily - but the attribute date (column) will always be an attribute. In other words, you must not remove the attribute date as a table column as the table name now.

  This decision (implemented as a multi table entity) have meaning when not having is not a better way to manage the physical aspects of the table. Partitioning for example would be a much better option to use - a single partitioned table, containing multiple partitions, where a partition physically contains data for a specific instant day (including the index).

  Basically, there is a very clear line between the logical data modeling and the material realization of this model. Oracle provides a bunch of features that you can use on the side of the material realization. As index organized tables. Table of clusters, partitioning and so on. But how you implement the physical model does not dictate the design of the logic model.

  However, the previous snapshot is used as a starting point for the following, or a subsequent repeat) you need to be able to quickly determine who is the nearest date start - easy if they are all in 1 table, can be more load trying to determine is whether a specific table at the time to a given date.

  I would use a management entity - that describes the metadata for a snapshot. As when it was created, the filter criteria used, the time it took (still useful for performance and troubleshooting purposes), be it an an active/valid capture instant or not - or any other attributes necessarily to manage this logical snapshot as a set of data.

  The biggest problem with a physical model that uses separate physical tables for the same entity, it is appropriate to use table name must be determined at run time. This means dynamic SQL. Dynamic SQL means an increase in complexity, open any SQL injection holes, having to deal with errors which would not intervene with static SQL, etc.

  If this approach to your data model's physical implementation needs a review carefully to ensure that it works as efficiently and effectively as required.

• question about the inability to meet the Windows Mail links

  I use Windows Vista, Microsoft 7.  A year ago I moved to a new location and subscribed to a new ISP.  I'm not changing my email provider preferred to Windows Live Hotmail and kept the same e-mail address.  However, I was never able to answer e-mail links, I get through links web page by e-mail, or in a specific instance of frustrating, their responses to a Yahoo Group that I belong to.  The e-mail program that opens isn't just Windows Mail, Hotmail.  When I click on the link provided I always get a message similar to the following: "task: send msg POP3 Local Area Network Failed." Details: Secure (SSL): no, Socket Error number 11001 error 0x800cc0D the host 'SMTP' could not be found. Please check that you have entered the server name correctly. Topic: test new downloaded OpenOffice org doc. POP3 ACCT: Server SMTP Protocol SMTP Port 25 ".  This has something to do with the fact that last February my hard drive has been damaged and I lost and do not re-install the Microsoft 2007 family and Student Edition and use Open Office.Org rather to my documents?  Is there a solution?

  Thank you.

  is there a solution to my original problem?

  It's hard to say. It depends on if this part of your description of symptoms is bad or just does not work properly:

  The e-mail program that opens isn't just Windows Mail, Hotmail.

  There is no support for what you do with a Hotmail account (unless just using Windows Live Hotmail as a mail client), so if you went on the forum WLSC that you have been referred to them could help you find a workaround.

  I don't know if WinMail still supports a connection to Hotmail very well. To do this, she will have to support the newer DeltaSync protoocol not the old WebDAV protocol. Outlook or WLMail would have better choices as default email for this client. Otherwise, you will need WinMail to connect to Hotmail as a POP3 account, and almost certainly not be able to do it using host names that you have tried. Yet once, find you better information and support for this on the WLSC. ; }

  Otherwise you can always check for addressability and connectivity using this SMTP host name and port number. It's unusual, but not necessarily incorrect according to the DNS of your ISP. You can use telnet in a cmd window to perform such a check:

  Telnet smtp 25

  and see if you get a prompt to enter a SMTP request. If you don't enter QUIT

  Certainly, your computer is not connected to a domain or a domain environment. If you use your computer at home without any connected networks, it is not connected to a domain as such. By default, a computer would belong to a workgroup.

• Question about subjects, books and tables of contents

  I have a question about the subjects, books and tocs. I have a project that someone else created, and my task is to create a new topic and add it to the table of contents. I created the topic, but when I generate CHM project it does not appear in the table of contents. I tried to update the table of contents. What I think (I guess) could be the problem, is the 'links to the topics', when I see the links to the topics in other areas (old) they seem to have a link to the main book, but the new one is not mine. Could you help me? Thank you!!!

  It seems that you have a manual table of contents page, rather than using the table of contents of CHM.

  The toc.htm topic that you see in your list of topics is probably where you will need to add your new topic.

  If the table of contents was already populated when you inherited the project, I suspect the previous author was using it just to keep track of the topics they had added manually to the topic toc.htm - added the CHM topic in summary you did mark the column of the table of contents in the list of topics like '' Yes. '' then add to the toc.htm manual is not. Hope that makes sense.

  P.S. Just guess that it is installing what I can see in the screenshot. It is quite unusual, so I hope I'm right.

• Questions about tables in text boxes

  When I convert the text to a table, there is a small space between the text block and the table. I have two questions about this:

  1. Is it possible to remove this gap? I put the text block options set spacing to 0 and gutter to 0 and spacing of table before and after to 0.
  2. Is it possible to create a table that is not in a block of text, especially when converting text to a table?

  Attached is a few screenshots that I hope will be useful. In the first image, East of the limit of the framework text in magenta and the structure of the table is in light blue. The gap between the blue magenta and light vertical lines on the left, that's what I want to remove.

  

  Tables are always in a text frame, and in fact, they are part of a paragraph, so I would check the assigned to this paragraph paragraph style and see if there is a left indent applied, or perhaps a paragraph alignment is set to something other than the left.
