• Merge Partition - Space Question

  We have a large table in 10g which has been partitioned from list. As the time has passed data with a valid value is not in any of the lists of the partitions has been inserted several times. These data fall into the default partition

  So we have something like this:

  Table ERRORS

  Partition E_1 values ('A', 'B', 'C')

  Partition E_2 values ('L', ', 'n')-size 600G

  Partition by default E_DEFAULT (but contains data of a single value 'Z') - size 50 G

  Now the seller would like to fix this by adding the values of 'Z' to E_2.

  They offer the following:

  ALTER table split partition (partition E_TEMP, E_DEFAULT) E_DEFAULT ERRORS;

  ALTER table merge E_TEMP, E_2 partition in partition E_2 ERRORS.

  I'm fine with the strategy. I have no doubt that it will work.

  I'm afraid that because the size of the partition is so great the merger will require a 650G extra free in the tablespace. Sellers seem to think that it will just add the 50G to 600G.

  Looking at the documentation, the merge partition section shows:

  "Use the ALTER TABLE ... M ERGE PARTITION statement allows you to merge the contents of two partitions into a single partition. "The two original partitions are deleted, as are all the correspondents index."

  This means to me that it takes two and creates a third, thus requiring the 650G of extra free space.

  But is this always the case if the third partition is actually one of the two being merged?

  For what it's worth, my plan was:

  Failure to Split

  Change the new partition with an empty temp table

  remove the new partition

  Edit E_2 to add the new value

  Insert ERROR select * from temporary table.

  drop temporary table

  I think that this requires free space of 50G.

  Thank you

  My main question, however, and this that I can't test (or do not know how to test) is the solution of partition of merger proposed by the seller requires free space equal to two partitions (in this case 650G) original to work? The seller says no. I think, but can not find documentation or evidence, Yes.

  If the seller says no, ask them for proof. I'm not aware that the internal process has been documented. But you should be able to test quite easily.

  The only reason why a new segment will be created being is if the data would actually be moved. In order to test whether the data is transferred.

  If the data is not moved, it's the same segment as before.

  1 put a line in P1 - examine the IDENTIFIER line

  2 put a line in P2 - examine the IDENTIFIER line

  3 MERGE P2 P1

  4. determine if the data transferred - what ROWID changed?

  The ID will be different if the data has been moved to a new segment.

  WA, AAAV74AAEAAAAtjAAB, 4, 2915, 1

  NV, AAAV73AAEAAAAtcAAA, 4, 2908, 0

  Note that the ROWID for 'CA' and 'WA' values are different. This means that the lines have been moved. The file number is the same, but the block numbers have changed as to have the line number for 'WA '.

  The fact that existing lines have been moved at all should answer your question about what really makes Oracle. In other words, is NOT just to add the 'WA' line for the existing partitions.

  If you do a SPLIT, but the data of the existing partitions is NOT affected, no data movement is performed. Check this example and see that all existing ROWID components remain the same

  ALTER table part_list split partition p_default ('OR') values

  in (p_or partition, partition p_default)

  He has not given "GOLD" in the partition by default so that Oracle has simply ignored this segment and created a new one for the new partition.

• resize boot camp partition, formatted and installed windows 7 - now cannot open in vmware fusion

  Here are the steps that I took...

  1 has started with the copy of Windows XP in the boot camp partition. "This is accessible from VMWare Fusion."

  2 resized (from 6 GB to 18 GB) and formatted the boot camp partition.

  3 successfully installed Windows 7 directly in the resized partition boot camp (not through VMWare Fusion).

  4. starts in OSX (latest version), open VMWare Fusion and attempted to access the partition to boot camp/vm. Received an error message charging me to disassemble and reassemble the physical disk changes. However, since I did it, he cannot find a bootable disc, therfore making it the useless bootcamp VM.

  Any help would be appreciated.

  Paul

  Note: These steps assume that you have a default Apple installation of Windows and a VMware Fusion Boot Camp Virtual Machine default partition and if you changed the Boot Camp partition the Virtual Machine to add additional hard disks to be virtual or RAW disk then do not use these instructions unless you backup the Boot Camp partition the Virtual Machine package first.

  1. If the merger is open, close it.

  2. in a Terminal (/ Applications/Utilities/Terminal) copy and paste command, as the following and then press Enter and it will remove the Boot Camp Virtual Machine meta-data partition. Note: This does not affect the Boot Camp partition to install Windows. Also make sure that you copy the entire command below "rm" line at the beginning of the ' (quote) after the p in the Camp. "

  RM - dfr "/Users/$ the specified item was not found./Library/Application Support/VMware Fusion/Virtual Machines / Boot Camp."

  3. start Fusion (/ Applications/VMware Fusion) and select the Boot Camp partition on the library of the Virtual Machine window, and then click the run button.

  Notes: Then, an authentication dialog box appears. "VMware Fusion requires that you type your password." Enter your name and password, and then click OK. (It is necessary to remove the Boot Camp for the merge partition to access it directly).

  Then, we should see a Boot Camp partition message stating "VMware Fusion prepares your Boot Camp partition to run as a virtual machine. This may take a few minutes. This occurs once. »

• Help in the merging of data and create mailing labels

  I have a CSV file with three field ("name, envelope" "" = address"and"City ST Zip") and 245 records.

  I have the labels that correspond to seven on a page.

  I have the designed document. I am able to get the fields inserted, but... when I merge, I get the first page with seven the first record labels, the second page with seven second record labels, page 3 with seven third record labels. You get the photos. I want seven different addresses on each page. So... instead of having more to 35 245 pages.

  Is this possible or should I find a way to make my drawing in Word? * sigh *.

  Everyone made the same mistake; you set seven (records) to your InDesign document, are not.

• Partitioned Tables and indexes

  Hello
  
  
  I have a question on the table and index partitioning. My scenario is:
  
  Charge 2 mio records in table T once a month. Loaded records are added to existing records, and once loaded data is never changed.
  At some point, I want to delete the older recordings, so I intend to this partition table.
  
  T table looks like:
  

  create table t (id       number(10) not null  constraint t_pk primary key,
                  period   number(10) not null,
                  contract number(10) not null,
                  attr     number(10) not null);
  
  create unique index t_ux1 on t(contract,period);
  
  create index t_ix2 on t(period);

  My plan is to partition T over the period, and I'm trying to read through the concepts
  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14220/partconc.htm#g471747
  
  
  My question is now, how to manage the indexes, the t_pk, the t_ux1 and the t_ix2. Concepts of say,
  
  «1. If the table partitioning column is a subset of index keys, use a local index.»
  
  "2. If the index is unique, use a global index. If this is the case, you are finished. »
  
  
  So, that's how I read it
  -t_pk is unique, so this should be global
  -t_ux1 of columns is a subset, unless I have misunderstood (?), which should be local
  -index t_ix2 column is the same as the partitioning column, so it must be local
  
  Is this right, this t_ux1 should be a local partioned index, even if the period is the second column in the index?
  
  If true, what will happen when a partion fell?
  
  
  I am new in this area, so please feel the comment as you wish.

  Is this right, this t_ux1 should be a local partioned index, even if the period is the second column in the index?

  A partitioned index locally can only be defined as unique if the partition key is part of the columns in the index. Imagine what the database would have to do if this is not the case: in order to verify if a newly added or updated value violates the uniqueness, it will have to travel all the partitions in a serialized operation - means that no one else could do the same thing at the same time. Since he is a killer of serious scalability in terms of locking and contention, this is not allowed.

  So: Your T_UX1 index can be defined as a unique index that is local because it contains the partition key. Although the index is not prefixed ("Prefix" means that it is divided by the left side of the columns in the index) which means that there may be access patterns where all partitions should be scanned or the optimizer cannot use a method of size of effective partition according to the way the index is reached.

  Your T_PK index cannot be set as local because it must be unique (you can not use a local non-unique index in this case), but does not contain your partition key. It must be a global index. An overall index can be partitioned as well (different from the underlying table) but it doesn't have to be.

  Depends on how you access your data you have not T_IX2 index when partitioning by this key because it corresponds to the partition key and therefore could not actually be used by the mechanism of partition pruning that limit your query to the scores of individuals.

  If you have more than one MAS environment where running queries are used longer, you should be fine with the index the in general (because they could be analyzed in parallel in parallel operations), but if you have an OLTP environment, then you should avoid local no prefix indexes due to the potential problem that you need to analyze all partitions.

  Be borne in mind that with partitioning adds an important layer of complexity to other areas: in particular the options available to the optimizer and analyze cost optimizer statistics. Depends on how you access your statistical data must be maintained on several levels now (level of score and at the global level, in the case of subpartitioning may be still at this level). If your data is important and you rely on "global" level statistics (these are always the case when the optimizer at the time analysis cannot limit access to a single partition) then in the pre - 11 g databases analyze these "global" level statistics can take a lot of time and resources, since actually , you need data several times (once for the partition and even global level).

  Presenting this partitioning may mean other potential problems in terms of execution that change (not for the better sometimes) plans and how to effectively collect statistics. Note that g 11 addresses the issue of 'statistics' by introducing the so-called "extra" global statistics. Greg Rahn wrote a [blog note | http://structureddata.org/2008/07/16/oracle-11g-incremental-global-statistics-on-partitioned-tables/] on this nice feature.

  >

  Since you're already on 10g, you can specify the database to update the scores of the local index using the UPDATE of the INDEX clause, while 9i could maintain only an overall index and it is up to you to rebuild the local index partitions after the partition DDL on the table (according to the DDL operation).

  1. back up OSX by using Time Machine - use Time Machine to back up or restore your Mac - Apple Support . The disks that you can use with TM are Backup that you can use with Time Machine - Apple Support .

  2. boot into Internet recovery - OS X: on OS X Recovery - Support Apple (CMD + Opt + R).

  3. clear your internal drives. Use the utilities-> disk utility to erase your internal drives. If this does not work, we can manually rebuild the disks.

  4 restore OSX using the links in step 1.

  5. run SMC/NVRAM reset without any connected external storage.

  6. run the wizard of BC and install Windows.

• Recovery Copyright OS 8 times merged partitions recovery in other partitions

  Could you please help me one more problem.

  My laptop is copyright OS 8. When I divided the 700 GB partition

  into 3 partitions (C, D, E) to the desired capacity (100 GB, 300 GB, 300 GB).

  But then the OS cannot be opened. I've converted type GPT to MBR disks

  format to install the new OS but the recovery of scores accidentally merged in other partitions.

  Now I can't use the original OS yet. Then I installed OS 8 of Dell (I know

  Copyright BONES embedded in the BIOS of the laptop).

  And I tried in vain several ways to recover the operating system of the key copyright.

  Could you tell me to resolve the situation to go back to the original OS.

  Could you please check the key of this laptop Dell system.

  Looking forward to your help.

  Thanks in advance

  If you need the key only for product activation, see here:

  If you need clean install, you need either a Windows 8.1 .iso to detail that requires purchasing a license of the retail Windows 8.1, borrowing from a friend or informal download (deprecated) sources or you need a Dell Windows 8.0 reinstallation DVD/USB (recommended). In the case of the USA or the CA, you can fill in the following form:

  If outside these areas, you need to call Support technique Dell.
