• Doubt on High Water Mark

  Oracle 9i
  
  The high water to _TABLES s/n
  
  The data dictionary keeps track of blocks that have been populated with lines. The high water is used as end marker during a full scan of the table.
  
  High waters are stored in DBA_TABLES. BLOCKS
  
  My doubt is
  
  When the full Table Scan is performed
  
  When the table contains fewer blocks DB_FILE_MULTI_BLOCK_READ_COUNT under high water, which can be read in a single I/O call, regardless of the fraction of the accessed tables or current index
  
  Dount 1
  which means according to my understanding, correct my if I'm wrong
  
  That a table contains blocks and if the number of rows in the blocks is lower than statistics in DB_FILE_MULTI_BLOCK_READ the optimizer based on CSSTidy then performs a full table scan to retrieve the data in a single I/O transaction
  
  Question 2
  If a table TabA contains 3 blocks B1(A1,B1,C1), B2(A1,B2,C2), B3(A1,B3,C3).
  
  Now if the data A1, B1, C1, A2, B2, C2 are deleted then the blocks B1, B2 are deleted or they will be empty
  
  Question 3
  When the last full scan of the table is performed on the Table in TabA, the high tide is set at top of B1.
  (According to my understanding high water mark is set by the last full table on a table scan)
  
  Then when data are removed i.e. edata in B1, B2 deleted then the high water mark is reset to B3 or is it still top of B1
  
  If it's still high in B1 then
  When the optimizer tries to determine what type of analysis to extract the table (A1, B3) data
  
  So how it will determine if, to make the full Table Scan, i.e. If the tide is not reset then when he tried to pick up the A1 then block 1, 2 are empty, but if the tide is not reset then obviously the dat which can be read in a single I/O operation but the optimizer feels it's expensive because the high tide is not reset to B3
  
  Thank you.

  Not quite, but close. Perhaps a picture would help. For simplicity, I will assume that there is place for one line per block, but the basics are correct.

  If you insert a new table 4 ranks, you'll have something like this:

                     H
                     W
  -----------------------------------
   B1 | B2 | B3 | B4 |    |    |    |
  -----------------------------------
  

  where HW brand the leaves high-water, and the empty blocks on the right are attributed to the table (part of the original measure), but have never been used. If you delete the B1, B2 and B3, you'll have something like this:

                     H
                     W
  -----------------------------------
      |    |    | B4 |    |    |    |
  -----------------------------------
  

  A full table scan, for some reason, all the blocks until the high water mark (i.e. the end of the B4) will read, because Oracle is unclear if there is indeed some lines in the block or not. He knows just that it might be because they are below the high water mark.

  Now, if you insert B5 and B6 you'll get something like:

                     H
                     W
  -----------------------------------
   B5 | B6 |    | B4 |    |    |    |
  -----------------------------------
  

  Since there is space below the high water mark. A full scan will still be read until the end of the B4. Now, if you add more than two lines B7 and B8, you get:

                          H
                          W
  -----------------------------------
   B5 | B6 | B7 | B4 | B8 |    |    |
  -----------------------------------
  

  A row has been added below the high water mark, because there was space but the second was added in a new block and the high water mark was moved at the end last block used, and even if you remove all lines (removal of t) high water will remain in the B8 and a full scan reads all the 5 blocks.

• AnyConnect VPN - how to find the high-water mark?

  I am looking for a way to determine the maximum number of simultaneous connection experienced on our ASA 55xx with AnyConnect SSL VPN clients. The IPSec protocol seems to have had such a statistic, but I can't find the equivalent for SSL. If anyone has an idea here, I would be grateful. Thanks in advance.

  PS > ASA running OS v8.2 (5) for the moment.

  'show the vpn-sessiondb summary' should show you the maximum simultaneous connection to the SSL/AnyConnect client.

  Here is the command for your reference:

• Is there no matter what it is called line high water mark for the data files?

  Hi all

  I'm a little confused about that. Many links suggest that HWM is for Segments (data index etc.). But at the same time, I see a lot of discussion (on this forum as well) which suggest that the HWM is an attribute of the data file.

  for examplefind a watermark on a data file

  Please specify.

  Thank you

  Two main uses are the direct path loads and loads Parallels. Each of these adds to the data above the high water mark of a segment and then moves the mark at the end of the data that have been added. These loads are faster, because the freelists and extensions and the blocks being loaded must not be checked for existing data.

• RMAN relationship wit high water

  Hi gurus
  
  I use oracle 10g 10.2.0.3 in AIX operating system. According to the database tuning activities I reset the high water mark of the server database and recovered about 15 GB of space. Is there any show gain opportunities in while taking RMAN backup? So far I know RMAN do not never use block in the backup, so that crashes I have reset as being free of H/W will include in RMAN backup? Please give me your valuable suggestion.
  
  Concerning
  
  JAV

  If you have reset the HWM rebuilding segments such as the BLOCK_ID + BLOCKS from DBA_EXTENTS highest value for a data file has now "shrunk"... but you have resized not the data file: there will be no difference to RMAN. RMAN will continue to save these blocks above the HWM because they have been used at some point in the past and had been formatted.
  RMAN excludes only blocks if they have not been formatted - so, the HWM for RMAN is the last block never used - currently in use or not.

• What is the advantage of the high water line?

  Hello

  When I remove the enormous data in table then the high water mark always on the same position.

  1. then deleted block still on the data file then why? I understand that these blocks is not used and it is empty so when he used?

  2-why oracle do not recover these block when automatically delete us the records? and we must do to help shrink the command?

  3 - Why before retractable data we must allow movement of line? What is the meaning of movement of the line. and why it is disable by default, no impact on performance so afford him?

  4. i try to reduce and remove the space allocation for some gigantic data, but still tablespace free space is always the same, does that mean?

  Thank you

  (1) the deleted data are always in the data file, because it is the least expensive way to implement a delete.  It is much faster to just things like free brand rather than incur the cost of, say, block formatting when the last line is deleted.  Most of the time, you remove one or two lines - it would be unwise to undergo as a load whenever you delete a few lines.  Free blocks will be used during the insertion of subsequent data (or during subsequent updates increase the size of existing lines and have to migrate to the new blocks).

  (2) because the shrinkage of the segment is expensive.  If you did that every time that you deleted a single line, deletions would be orders of magnitude more expensive than they are today.

  (3) because the shrinkage of the segment means that you physically move potentially every row in the database.  From a functional point of view, this amounts to potentially remove all the ranks of the block in which it is and moving it to a different physical location at the 'head' of the segment so that all free space is at the "tail" of the segment and can be released.  Of course, it is unlikely that all ranks have actually be removed and reinserted.  But a significant fraction of them.  Among other things, this will change ROWID line that would break any code that was waiting for the ROWID remains constant, this is why you need to activate the movement of the line.

  (4) you must show us exactly what you are doing (the exact series of commands that you run, how you measure the free space, etc.).  If you just insert roughly the same amount of data in the table that you deleted over time, shrinkage of the segment is unlikely to be useful.  From the point of view of application performance, for example, you only care about high tide if you perform a full scan of the table.  But it is rarely wise to write code that is to do a full scan of a table that is large enough so that you can delete a 'huge' of data in the table number.

  Watermark is available using the Oracle Multimedia Image Processing ORDImage object. The static methods provided in the ORDImage relational interface are the best approach for use with images related to APEX which are not stored in form of ORDImages. The documentation provides some simple examples.

• Help! My Macbook Air has a high memory pressure.

  Product: Macbook Air in early 2015

  Plug-

  256 GB of flash storage

  1.6 GHz processor

  4 GB memory

  OS X Yosemite - Version 10.10.5

  A few weeks memory of my Macbook Air pressure continued to increase, most of the time he was in the green zone, but it has been several times that I had the pressure of memory to be in the yellow box with a few tabs in Google Chrome. In addition, the Kernel_Task continues to rise as it was around 380-390 MB a few weeks ago and now he's moved more than 500 MB. I tried to restart and stop the computer several times as an attempt to decrease the Kernel_Task and even thought that the memory pressure is high, the CPU doesn't have a lot of problems, because it is essentially inactive between 65 and 80 percent.

  What it looks like without all the eleven (shown) Google Chrome processes running? You should never see Swap used, and that tells me that you are using too many applications for your 4 GB memory available on your machine. With this RAM limited, you have to be very selective of what applications and browser tabs are open (you use) quit everything.
