Fastest way to take data

• The fastest way to import data for large tables

  Hi friends,
  
  I recently joined a billing product put up a team for TELECOM giant. Under the procedure of installation/initial tests, we have huge data (size of almost 1.5 billion records / ~ 200 GB of data) in some tables. Currently I use impdp to import. It takes a long time (almost > 9 hours to load these data).
  
  I tried the ways below to import the data (all of these tables is partitioned):
  1. normal impdp (single thread that is, parallel = 1): it takes a long time (> 24 hours).
  2. normal impdp but partition-wise. It was completed in relatively less amout of time compared to the 1st method.
  3 fall drop the index, framed adding another scheme in the same forum that includes data, and then recreate the index (whole process takes about 9 hours)
  
  My questions at all:
  1. is there any other way/trick in the book that I can try to put the data in less time
  2. what I pointed out that even if I give parallel = 8 or more, sometimes parallel workers are laid and sometimes not. Can someone tell me why?
  3. How can I come to know (before running the impdp) that my parallel article will spawn parallel workers or not. As to how I will come to find out, I searched this topic but without success.
  
  
  I don't know what strategy to follow, because it is an involved and repetitive task for me. Because of the task above, I am not able to focus on other DBA tasks because of what comes to me.
  
  See you soon,.

  assuming that you have a table with 3 clues, then create a script for each index (reblace index_name_n with your index name) and start them at the same time, after the importation of the table is complete

  DUMPFILE= or NETWORK_LINK=
  DIRECTORY=DATA_PUMP_DIR
  LOGFILE=
  CONTENT=ALL
  PARALLEL=1
  JOB_NAME=IMP_
  INCLUDE=TABLE_EXPORT/TABLE/INDEX:"IN('')"
  TABLES=.
  Change the following settings when importing:
  increase pga_aggregate_target
  increase db_writer_processes
  db_block_checking = false
  db_block_checksum = false
  the value undo and temporary ts autoextend
  Set noarchivelogmode
  create logs of restoration of 4 GB

  The fastest way to transfer data between two Lacie Thunderbolt external HDs
   
  			 
  Hi all. I have a ton of music on a Lacie Rugged 1 TB Thunderbolt/USB 3.0. I use to mix. I have a Macbook Pro 15 "w 2015 / retina with Thunderbolt ports two (2) and I try to use it to transfer all the data from my Lacie Rugged drive to my new Lacie 3 to Desktop HD that was Thunderbolt (2) and USB 3.0 and use also the new Lacie Desktop drive as my primary for backups time machine.
  In order to transfer data from the rugged drive (THE most RAPID WAY POSSIBLE) on my new Lacie desktop drive I should? :
  (A) connect to each port thunderbolt on the laptop itself?
  Or
  (B) connect the Lacie Rugged HD to the new Lacie Desktop HD then the Lacie Desktop HD to the thunderbolt on the laptop (daisy chain) port?
  Thank you!
  			 
  MacWorld has done some tests on this and found a slight increase in performance with the devices connected directly to the laptop. So don't try Garland!
  		   
   
  		     
  The fastest way to load data
   
  			 
  Option 1:
  Insert the statement with:
  table view: NOLOGGING
  insert mode: APPEND
  in ARCHIVELOG mode: noarchive log mode
  Option 2:
  DEC in NOLOGGING mode
  The two options above would generate no redo log. What is the best for performance? I'm loading large or lines (a few million) on a daily basis and it is an intermediate table, so there is no problem when the reprocessing failure.
  			 
  The answer may depend on the availability of memory and index.
  ETG requires you to create indexes subsequently - but each index requires an analysis of the table.
  Insert / * + append * / can optimize for indexes by capturing the values of the columns needed as data is loaded, and then creating the index without having to re-read the table.

  The fastest way to transfer files between servers...
   
  			 
  I have a question regarding what would be the best option to accelerate the transfer of files between 2 servers to our VMware environment. We plan to spend our GroupWise email from netware to windows and upgrade to Groupwise (v7 to v8) at the same time. We will anticipate moving about ~ 125 gigabytes of data (files ~ 517 000) and expect that it will take several hours. We would like to minimize this time better we can so we wonder what would be the best configuration of things to get there? Two virtual machines on the same host? Two virtual machines on the data store even? On different hosts, or data warehouses? Our configurations are listed below:
  -In the course of running vSphere 4.1 ESXi
  -Data stored on 2 Dell Equalogic 5500 without
  -SAN one in each of the 2 sites, physically about 3 miles away
  -3 guests, 2 to a location and 1 in the other (same places the San)
  -Transfer of data from Netware 6.5 source, destination will be Windows 2008 R2 DataCenter
  -Links gigabit between all the elements of our VMware environment, including the link between the sites (on optical fiber).
  -3 guests are able to run all our virtual machines without overloading, so if we go to the virtual computer to another host, it is not a problem.
  We would like to know what is the best way to put everything in place for the transfer, so that we can prepare before hand. Any suggestions?
  Thanks in advance.
  			 
  Well, the fastest way would be to offload the clone/copy to the San operation. If your configuration supports VAAI then the clone would happen completely on the SAN by assuming that the source and destination storage device is the same SAN. Would it be different San then the network factors in anything. For what is running on the same host, which would be beneficial for cloning a virtual machine (mainly memory footprint) should not take place on the network.
  I hope this helps!

  The best way to migrate data... Opinion please...
   
  			 
  Guys,
  I'm working on a solution for a customer who needs to move in a new SAN SAN data.
  Existing SAN is attached to the ESX server farm and is very close to the location of a new SAN. In your opinion, what is the best way to move data without interruption to VM ESX farm?
  I know we can do SAN replication, but right now, I don't know if the SAN is still the same provider.
  I know we can do Storage VMotion. In this case, he should present the new SAN somehow for the existing ESX servers.
  I know that we can probably use the converter to migrate virtual machines. This can take some time because we would go over WAN.
  What are your thoughts?
  Thanks in advance for your comments!
  			 
  With 4 TB of data, I wouldn't pass on the replication SAN or WAN solution of optimization of the property, and it can fly quickly with 4 TB of data that you use storage vmotion which basically depends on how your WAN links are, if if its quick to go for it.  There is not another free solution then this but if you can manage somehow to make backup of system state of all virtual machines, and then you can ship these backup data to remote locations and import, save back to clusters.  You have to do the actual calculation how fast you can Transfer data from the siteA-> siteB Mbps?  This will give you a clearer picture of how long it will take and picture plan here.  I could do that during maintenance or weekend windows that are the least impact to users and systems.
  If you found this information useful, please consider awarding points to 'Correct' or 'useful '. Thank you!!!

  The fastest way to the files and folder to move
   
  			 
  I'm moving a lot of files to another drive and it takes a long time.   I do travel in the LR library now and an alternative is to move outside of the LR and use the catalog import option to add (don't know if it's a more quickly).
  You can select multiple folders in the LR library to move to the same location or do you need to do one at a time? This would be onen advantage to do outside of LR.
  Any thoughts?
  			 
  You cannot move several files in Lightroom.
  The fastest way is to move your "Pictures" folder all OS, then re - link in Lightroom by right-clicking and choosing 'find the missing folder '.
  If you need to move several subfolders selectively, then there is no quick way. You move quickly in the BONES and then go rebinding in Lightroom or move them slowly one by one in Lightroom.

  Is there a way to use data formats i.e. Go Mo Ko in numbers?
  I am trying to add the size of the library files to estimate the needs of the HD. If I had the files on my system I could just put them in a folder and the operating system would be to calculate them for me, but I don't have them yet. I have a list of files and their size in GB.
  Someone has it worked?
  			 
  I suggest the following:
  
  Create a second table called "convert".
  In this table, enter the first column as show (pasted here so you can copy)
  
  
  
  
  Value
  
  
  Divide by
  
  
  suffix
  
  
  
  
  0
  
  
  1
  
  
  b
  
  
  
  
  400
  
  
  1024
  
  
  Ko
  
  
  
  
  1000000
  
  
  1048576
  
  
  MB

  1000000000000
  
  
  1099511627776
  
  
  TB
  
  
  
  
  Appropriate now in the table 1 use the conversion table to change the size of the files in the format:
  
  "C2 = ROUND (B2÷VLOOKUP (B2, Convert::A:C, 2, 1), 2) &" "& VLOOKUP(B2,Convert::A:C,3,1)".
  It's shorthand dethrone select cell C2, then type (or copy and paste it here) the formula:
  "= ROUND (B2÷VLOOKUP (B2, Convert::A:C, 2, 1), 2) &" "& VLOOKUP(B2,Convert::A:C,3,1)".
  Select cell C2, copy
  Select cells C2 at the end of the C column, paste

• What is the best (fastest) way to convert Apple folios (iPhone and iPad), Android (phone and tablet)?

  We have an app for Apple devices multifolio and we will include an Android version.

  How is the best and fastest way to do it?

  Do I have to copy all my source files (* _v.indd) in another folio folder set and run through them, scaling to adapt to the direction of Android, i.e. to convert form 1024 x 768px to 2560 x 1600. (I know it leaves a black band, I can always fill it up).

  And something similar for versions of phone?

  THX.

  That would be the best way. Are made, IMO, a waste of time and effort.

• Is there a way to remove data from a combination of individual Member?

  Hello
  
  Is there a way to remove data from a combination of members particlular, as if I want data for the month of sales for the month of May to remove and keep the rest how to do?
  
  Thank you.

  You don't mention if this is a cube ASO or BSO and which version you're on. If OSI, then a script to calc using a fix to erase the part of the data is what you want. There are references to him by the other prople. If it's an ASO cube, then you use a MaxL command with MDX syntax to make clear assuming you're on version 11.1.1.X or superior. If you are on a lower version, it becomes more complicated.

• Fastest way to check if a file exists

  Hello
  
  I have a table with more than 100 M records. What is the fastest way to check if a record exists or not. Currently I use Oracle 11.2. Here is the SQL code I used, id is the primary key of the table_test.
  
  Select count (*) from existFlag
  of table_test
  where id = testID
  ;

  Yes, you could use double fusion using the clause, but a line of K + 10 k 10 inserts a line MERGE statements will be much less effective than 1 INSERTING rows 10 K + 1 MERGER of 10 K lines.
