time to update the index

Similar Questions

• update the indexed column

  I got a name emp table that holds at least 30000 lines and I had created an index on emp_city

  What happens if I update a value of emp_city? What effect will create it on the index or table?

  the index will be updated automatically?

  the index become invalid?

  the line in the journal in the index will be deleted and inserted?

  or updated in the journal will take place?

  According to the name of the field, I understand that the distribution is pretty sparse for normal index on emp_city.

  Will be better to create a bitmap index where you apply to this table with OLAP queries or not create an index on this field.

  I don't care

  If you have an index on emp_city or emp_city is a part of some regular index and you will upadate all value emp_city:

  the index will be automatically updated. (Yes)

  the index become invalid?  (No, but I suggest that you run statistics on index or table wole)

  the line in the journal in the index will be deleted and inserted? or updated in the journal will take place?

• Time to update the BIOS and firmware of remote management?

  I'll put up a 'new' ThinkServer RD630 (2954A6U). It was purchased for a project that never happened, and we are now dry and reuse to replace an old Office Server. The current firmware versions are:

  • BIOS: 2.05
  • ME: 2.1.5.73
  • BMC 1.7
  • IPMI 2.0

  Page 61 of the User Guide ThinkServer says, "update the BIOS on your server only if the new BIOS version specifically solves a problem you have. We don't recommend updates to the BIOS for servers that do not need. [...]"

  As far as I know, we have no problems. The system starts fine and runs Windows Server 2012 well enough.

  HERE'S MY QUESTION:

  Should I update the BIOS and firmware IMM (remote management) to the current version? Are there hidden problems, security issues or other concerns that it is worth?

  Other indicators of initial configuration that you can share with a new admin would be much appreciated, too! Thank you.

  With the help of the Lenovo Support, I was able to fix my problem where I couldn't get to the menu of the BIOS of the 630 RD (in F1) and all I saw was a cursor on the screen. I describe the procedure in detail here:

  Thank you to all those who commented above and especially to those who have sent me suggestions via PMs.

• What is the right time to use the index with force?

  I have an EMPLOYEE table.  I join with the ROLE, and it has only about 200 distinct values on column EMPLOYEE. EMPLOYEE_TYPE_ID.

  Select / * + INDEX (an i_employee_type_id) * / b.SID as EMP_NAME, b.role_cd in the ROLE

  Of

  EMPLOYEE,

  B ROLE

  where

  a.EMPLOYEE_TYPE_ID = b.EMPLOYEE_TYPE_ID

  AND a.EFFECTIVE_END_TS > = systimestamp;

  Is it a good idea to use the index?  .. Or let the full table scan.

  SQL > select distinct EMPLOYEE_TYPE_ID of the EMPLOYEE;

  238 selected lines.

  If you don't know it will help not to use.

  Personally, I found several SQLs with index finger tips (written by programmers thinking index access is ALWAYS GOOD) end up harming performance. Oracle made a reading diluvium full table scan, single index reads as follows, according to the % of the returned array it is actually faster to do a full table scan. The optimizer did a great job to determine this.

  If you think there are cardinality estimation problems, and the optimizer expects a large number of lines when there are actually few being returned, in THIS case a suspicion was justified. Even so, in this case, I prefer that oracle manages the flag itself.

  You can do this by running the SQL tuning advisor. In fact, it will trigger the optimizer checks that the estimates are turned off and it will create a profile for you. (A profile is actually a stored set of advice that set the execution plan for you). If at the point where the underlying data changes significantly and profile ends up hurting performance, you do not need to touch the code like you would with manually added notes, you can just disable or delete the profile and let the optimizer re - analyze the statement.

  Concerning

  EDIT: In case of small tables, it is preferable to just cache the whole table in the POOL to KEEP and let oracle scan if necessary.

  Edit2: With the notable exception of index fast full scans, which are diluvium index readings. But they are only relevant when the request is quite satisfied by the index and has no need to visit the table.

• Pages crashing all the time after updating the OS 10.11.3

  Hello, I have problems with Pages crashing since I received the update OS X El Capitan (10.11.3). Common problems are:

  • Pages could open documents with considerable delays: when I double click on a file, it may take up to 20 seconds before opening the document (at the same time, the only thing running is 2 tabs in Safari with non-intensive websites like Wikipedia);
  • Pages would not open to all documents: sometimes it refuses to open my documents either. When I choose for example a document on the 'Recent' via dock icon Pages list it will not launch it. If I wait for awhile and just click the Pages icon, hoping that it will be launched the document in the background, he brings just to the top of the window with the models as if I wanted to open a new document.
  • 'Missing font"all the time: I did not the latest changes to my fonts, but when I opened a document originally created in Pages (and not a converted copy of an old Word document) it always gives an error message "missing fonts" - particularly associated with Microsoft fonts. I downloaded and installed Cambria and Calibri manually and it fixed the problem... for about 8 hours, then he started again.
  • Beach ball rotation of death during the execution of simple operations: it's exasperating, but every now and then when trying to type or text in bold (and similar), the beach of death ball will appear, making the Pages does not.
  • Crashing before loading the same: when I force quit the app because it did not and then I try to run again, often they no longer again before loading the same. What the...?
  • Impossible to duplicate documents: at one time I thought that it is a certain file at the origin of all evil, so I tried it duplicate several times - which of course caused Pages to plant again and again. Same thing happened when I tried with other files.

  I had a similar problem before and it was fixed to restore the default fonts and removing duplicates in the FontBook app, but unfortunately it did not this time.

  I don't know what is wrong or why. It was working OK just a couple of days. Anyone else have similar experiences with it? Looks like Apple may not come out with an update that doesn't break the workflow of the people. But yay, more emoticons and pictures Live Webcam on the way!

  Because my Pages on El Capitan 10.11.3 v5.6.1 works very well with any of your questions, I believe that it is not Pages, but something out of Pages in your environment operating system as a cache of corrupt police, duplicate fonts, or damaged preferences file. Perhaps it is that you are too many applications running for your memory availability and Pages of hunger. All in due time.

  Let's start with a secure boot that will clear the system and local caches, rebuild the database of the police and then see if it stabilizes your use of the Pages.

  Secure boot

  1. Shut down your Mac.
  2. Press the power button and immediately press on and hold down the SHIFT key until you see the horizontal progress bar. I usually wait until it's an inch along before I release the SHIFT key. Personal touch.
  3. You will arrive at a login window. In the upper right screen, you'll see Safe Boot in red letters.
     1. After you type your password, stop, then press and hold the SHIFT key again once, before you click on the right arrow to open a session.
     2. Continue to hold the SHIFT key until your painting of icons on the desktop.
     3. Because many drivers are not loaded, graphics performance is not optimal, and may feel morose.
  4. Test Pages in startup mode to see if the problems have disappeared.
  5. Restart normally.
  6. Start Pages and open a document.

  Previous post the results of step 4 and 6. Have what improvements (if any) you noticed?

• Replace the index of an array with strings values

  I have a control table 2D (or indicator) CH x T: each cell of the table contains the voltage check for channel and time represented by the respective row and column.

  I would like to be able to scroll the data showing the names and time values to the Index screen instead of numeric values.

  For example, instead of see 0,1,2,3 etc. as line index values, I would like to see channel 1, canal2, canal3 etc..

  Is - it somehow possible?

  Any idea is welcome!

  Thank you in advance!

  See you soon.

  MG

  If you want to display the data in the form of a 2D array, but use channel & time as the Index display, you can use the rings of text and structure of the event.  You can reduce the table view if you only want to display one value.

• Using the index to extract data without filter predicate

  Hello
  
  does anyone have an explanation for the following scenario:
  
  I have a table T1 with an OID_IX index on column (object_id) - the table is a DEC dba_objects just to fill it with data.
  There are no other current index. The table and index are analysed.
  
  When I run the following query, the table is available in FULL (without using the index)

  The table contains 7 times more than the index blocks!
  
  
  any answer welcome

  The column is not defined as NOT NULL, then there may be values that are not in the index (because the index does not include null values). The useless predicate implies NOT NULL, then the index may be used.

• How to block the data grid to access the first row when updating the dataprovider

  Hello!
  
  I'm pretty new to Flex, and wonderfully, I have a problem. :)
  I use an AdvancedDatagrid to display data from a server with HTTPService. The script calls the server every 10 seconds (with timer) to update the displayed data.
  When I scroll the list and select an item (to see detailed in a textarea content) and the timer just fires, datagrid automatically jumps to the first line.
  My question is, how can I avoid this behavior?

  In addition, if the selectedIndex property is not visible, you may need to define verticalScrollPosition.

  think a little more, also record the value of the Boolean and game too.

  Finally, after assigning the dataProvider, you will need to use callLater() to delay defining the dgPosition

• rebuild the index partition

  Hello
  I have unusable a clue. Now I want to rebuild the index for this I have to rebuild the partition and the tablespace in two different command as
  
  Index_name ALTER INDEX REBUILD PARTITION p1;
  Index_name ALTER INDEX REBUILD PARTITION p1 TABLESPACE INDX_TS;
  now my question is when I run first command and check the index of fof status it shows not usable. In the same way when I ran only 2nd order also rebuild successfully. If I ran only 2nd command works fine?
  why it displays usable after only rebuild partition?
  
  
  I have script for all indexes on user like this
  
  Select 'ALTER INDEX' | index_name |' rebuild partition '. Nom_partition | ';' in USER_IND_PARTITIONS
  Select 'ALTER INDEX' | index_name |' rebuild partition '. NOM_PARTITION | 'SPACE '. nom_tablespace | ';' in USER_IND_PARTITIONS

  Why you set all the indexes to be UNUSABLE?

  (Please don't keep saying "unuse index", do you mean "occupies an unusable index"!)

  The instance / session SKIP_UNUSABLE_INDEXES setting determines the behavior of DML. In 9i, it is false by default. In 10g, it is by default true. Thus, in the 10g (unless you have changed it back to FALSE), INSERT/DELETE operations can succeed even if an Index is UNUSABLE. However, indexes to enforce PRIMARY KEY constraints or unique indexes (index created in CREATE a UNIQUE or apply INDEX of UNIQUE constraints) cannot be ignored by normal DML.

  (Direct path operations automatically update the index and, therefore, can leave clues in an unusable state temporary.) These look like actually to DDL operations and lock the partition table/preventing simultaneous updates).
