  table of partition not valid-how can I solve this... cannot do anything on laptop

  If you get an error about "Can't fixboot", then proceed to the next step.

  Type bootrec /fixboot (with a space after bootrec) at the command prompt, type enter.

  Type bootrec /RebuildBcd (with a space after bootrec), and then press the Enter key.

  If this is not successful, it is likely that the disc is not recoverable, and you will have to boot from the recovery disks to reinstall windows.

• Increases the size of the "HDD Recovery" folder on the partition "D".

  I am the owner of laptop Toshiba Satellite, recently, I noticed that my D: drive (unused) is saturated and after careful analysis I realized that the "HDDRecovery" file size is > 200 GB.

  I don't want to remove the file or remove image files inside that I need the functionality of recovery, but I have not a clue how to handle the recovery process to decrease the volume.

  Do you have an idea how this issue?

  Hello

  It seems strange to me that the size of the HDD recovery folder would increase up to 200 GB continuously. Probably for laptop computer stores files backup automatically in this folder, but I m not very well why

  However, I recommend you to create a recovery media (recovery disk) using the Toshiba
  Recovery media creator (this software pre-installed on the Toshiba laptop).

  The use of disk recovery (or USB key recovery) would fix the laptop back to the factory and even if settings you should remove the folder in HARD drive recovery or the entire partition, this partition, and these files would be created again.

  Hope that this information could be useful for you.

• THEME AND THE RECOVERY 2 250 G5305GR PARTITION X HP

  Is it possible to make a recovery for my pc partition (I made stupid enough to delete it before you reinstall windows when I had a few problems) and the theme preinstalled?

  Use the set of recovery disks or USB recovery media to recover your PC for the scheme of original score that your computer was delivered in.

  Pre-installed theme?  Please provide details.

• alter table Exchange partition

  Dear Experts,

  I could ask does change exchange table partition depends on the size of the table or partition?

  Thank you for your help.

  Best regards, Atanas.

  Hello Atanas,

  It's the good point: it does not depend on the size. Data is actually exchanged between the two segments, the work is only level 'dictionary': Oracle exchange the roles of both existing segments, it is now regarded as a table and the other as a partition, as opposed to their roles before the "swap partition.

  Thanks to this, Exchange a partition can be a very quick way of loading new data or old data archiving...

  REDA

  ID_CITY a VARCHAR2 is not a number.  Thus, although "less than ('10')" is correct for a VARCHAR2 ("equal or superior (10)"), where do you think the value '2' would go? '2' less than '10' is? Where would the '21' value?  Where would '56'?  Tip: '21' is less than '3' and 56 'is less than 6'.

  Also your first partition is defined as "less than ('1')", which makes no sense.

• Reclaim space after ALTER TABLE DROP PARTITION

  Hello
  
  I have a partitioned table. My requirement is to reclaim the space by dropping a partition of the table.
  
  Is it possibe to recover space for the tablespace by dropping a partition of partition table?
  
  Thank you

  Hello

  ALTER TABLE DROP PARTITION will always return the space to the storage to be reused by other segments.

  It's the ALTER TABLE TRONQUER SCORE, where you can specify DROP STORAGE or of REUSE STORAGE clause (in case of re-use, the space is not released and can be used by the new lines inserted in the same partition). The DROP STORAGE should be the default option.

  But for the fall of the score, you don't have to worry.

  Hello
  
  I wish that this command must be run in parallel. is this possible?
  
  ALTER TABLE xyz PARTITION MOVE xyz_p0608 TABLESPACE q208_ts
  
  Thank you

  parallel_clause
  
  Purpose
  
  The parallel_clause lets you parallelize the creation of a database object and set the default degree of parallelism for subsequent queries of and DML operations on the object.
  
  You can specify the parallel_clause in the following statements:
  
      * CREATE TABLE: to set parallelism for the table (see CREATE TABLE).
      * ALTER TABLE (see ALTER TABLE):
            o To change parallelism for the table
            o To parallelize the operations of adding, coalescing, exchanging, merging, splitting, truncating, dropping, or moving a table partition
  

  To parallelize append operations, coalescence, Exchange, merger, splitting, truncate, delete or move a partition table
  

• NOLOGGING in alter table split partition...

  Hi all
  
  Please can tell me where I would add the NOLOGGING in the below statement, or any other means by which I can stop to redo being generated
  
  ALTER table split partition EB_LOGS_082008 at (to_date('01-01-2010','DD-MM-YYYY')) NOLOGGING EB_LOGS into (partition EBLAST_TABLE, partition EB_LOGS_012010 tablespace EBLAST_TABLE tablespace EB_LOGS_082008) parallel;

  Wow... Grammar ALTER TABLE just constantly more and more complex, isn't?

  According to this:
  http://download.Oracle.com/docs/CD/E11882_01/server.112/e10592/clauses005.htm#CJAHABGF

  "For partitioned objects, the value specified for this clause is the physical attribute by default segments (and ALTER following... associated with all the partitions specified in the CREATE statement ADD PARTITION statements), unless you specify the logging attribute in the description of the PARTITION. »

  If I read that correctly, so if you want the NOLOGGING keyword to indicate more than just the physical default attribute, then it must be in the description of the PARTITION.

  So something like this, perhaps?
  Totally not tested, BTW:
  ALTER table EB_LOGS split partition EB_LOGS_082008 at (to_date('01-01-2010','DD-MM-YYYY')) into (partition EB_LOGS_082008 tablespace EBLAST_TABLE nologging, partition EB_LOGS_012010 tablespace EBLAST_TABLE nologging) parallel;

  Once again, this is an assumption and cannot yet pass the analysis.

  In regards to the perceived dangers of NOLOGGING operations, well, it is certainly something that must be clearly understood, but not to fear. The disadvantage of an operation NOLOGGING is that if you need to recover from a backup taken before the NOLOGGING operation, until a point in time after the operation NOLOGGING objects in the database that were submitted to NOLOGGING operations will logically corrupted and must be rebuilt.

  Finally, I fell on this can also be useful, regarding the optimization of SPLIT PARTITION operations:
  http://download.Oracle.com/docs/CD/E11882_01/server.112/e10837/part_admin.htm#VLDBG00304

• A table of partitioning, as every hour

  Hello
  
  I want to create a table and this table has a 24 (fixed) partitions for data every hour. If the partition column (date type) key is equal to '2009-01-17 01:05:09 ', it must be written second partition. If key of partition column equals '2009-01-17 00:05:08 ', it must be written first partition, even if the partition key is equal to "2009-01-24 00:35:47"it must be written to new first partition. How can I create this partitioned table? If we have a chance to write the substr function in the partition key, I could handle by using the partitioning of the list, but there is no chance to write a function in the column name partitoin except the to_date function key. Can you give me an idea or an example?
  
  I use Oracle 11.1.0.7.

• Question about Table of Partition MBR

  I have a Toshiba laptop running Vista Home Premium SP2 with processor Dual-Core of AMD Athlon 64 X 2, 1 GB of ram and 150 GB of HARD drive.

  My question is about the partition table in MBR. It shows 4 partitions it.

  I have the Ultimate Boot CD, so I took a look at the MBR. Here are 4 partitions occupying its table:

  1. (without drive letter)-file system: blank - EISA config partition type code'n - 1.46 GB -: x 27
  2 C: - fs: ntfs - system, boot, primary, active partition - 92,01 GB - code: x 07
  3 D: - fs: ntfs - primary - 5.98 f - code: x 07
  4. (without drive letter)-fs: blank - primary - 5,64 GB - code: x 17

  c: is free of 17%, d: is 99% free, the other two are 100% free

  Can you explain what the purpose of D:? What about the other two (with no drive letter)? I read somewhere that ' x 17' code means "hidden IFS (ex: HPFS)' & 'x 27' means a rescue partition... true?". Do I need them, or I can remove the part'ns 3 (other than c :) & make use of space?

  Looks like the recovery and BIOS utilities. You need to check with Toshiba so one any of them can be deleted.
