• What is bet' difference n allocate channel channel & back RMAN maintenance

  Dear all,
  
  Please tell me the difference between allocated channel & maintenance of BACKUP RMAN channel.
  
  waiting for response...
  
  
  Kind regards
  .................

  Allocate channel is used for the normal functioning of the RMAN. Normally, RMAN comes with a default (Auto) configured disk channel that can be used to perform the backup immediately. If you want to override the default on a temporary basis manually, then you can use the Allocate channel command.

  Maintenance channel is used for maintenance orders, catalog, change, overlap and delete. In addition, a maintenance channel is given by default. If you want to allocate, you can do it manually as well.

• RMAN parallelism Vs channel

  Hello friends,

  I have two bands as well as my RMAN configuration device type abt_tape parallelism 2. How did this effects number of allocated channels? What is the relationship between the channels and the parallelism? I lived manual confusion, but not for me.

  Thank you

  Hi RamaKrishna,

  Channel is what you create manually when you run a RMAN block. For example if you use the command as «assign channel...» "in an execution block, this means that you manually create channels for RMAN backup.

  But if you configure using parallelism "configure channel device type disk (or what type) 2 parallelism, this means RMAN will create two channels automatically if you specify"affect the channel... " ». in your execution block... However if your parallelism is 2 and you allocate 3 channels in your execution block, rman will replace the parallelism number 2 and create 3 channels, as you mentioned manually 3 channels in your execution block.

  Hope that it would ve you authorized.

  Kind regards

• RMAN channels

  Linux operating system
  Oracle version: 10g / 11g
  
  Hello
  I'm newbie with Oracle RMAN and in particular, I did not understand the concept of channels (CHANNEL of TYPE ALLOW disk...).
  I think this is the way to call the server processes on the side of RMAN that physically write the backup. RMAN can improve backup performance by parallelizing operations using multiple channels.
  
  Should what steps I use RMAN and understand the ALLOCATE CHANNEL?
  
  How can I assign multiple channels at the same time?
  
  Thanks in advance!

  Hello Raf,

  Assign you channels to create responsible processes of processing the files.
  If you add more channels (and you have a number of processors to support), you can speed up the tasks up to a point.

  to use RMAN, you are good to go right after I installed the software and DB.
  to make a backup (on an open archivelog on db mode), simply:

  $ rman target /
  backup database plus archivelog;
  

  After that, you can complicate the script.
  the syntax has so many choices and opportunities, I have to refer to the documentation:
  http://docs.Oracle.com/CD/E11882_01/backup.112/e10642/TOC.htm

  It will be useful.
  BR,

  You mix auxiliary channels and auxiliary bodies.
  The auxiliary tasks are to maintain the rman repository, and you can't use them to restore the archives.
  Also the duplicate database is robust and powerful and will automatically restore missing archives as long as they are on the tape.
  Therefore you do not have this code.

• difference between the parallelism and assign channel

  What is the difference between
  
  RMAN > run {}
  allocate channel c1 device type disk;
  allocate channel c2 device type disk;
  }
  
  AND
  
  RMAN > configure channel device type disk parallelism 2;

  9i / 10g:

  RMAN > run {}
  allocate channel c1 device type disk;
  allocate channel c2 device type disk;
  }
  -Online you manually assign 2 channels.

  RMAN > configure channel device type disk parallelism 2;
  -Online RMAN allocate automatically 2 channels if you do not specify assign channel in your building.

  2 = 2 there is no difference, but if you do:

  RMAN > configure channel device type disk parallelism 2;
  and then
  RMAN > run {}
  allocate channel c1 device type disk;
  allocate channel c2 device type disk;
  allocated channel c3 device type disk;
  }
  RMAN uses your manual assignment and the degree of parallelism is 3

  In any case RMAN will ALLOCATE channels, maybe that they will really be USED.

• niHSDIO VI of dynamic channel assign

  It might be a silly question, but I am struggling to find the answer I'm looking for.  When using the niHSDIO assign dynamic channels VI with the PXI-6552, how to determine which channel is assigned to which pinout of the PXI?

  I call the VI as follows:

  

  I was able to stumble upon this article that shows the pinout diagram; However, it does not seem to correlate the VI channels to the PXI pins:

  

  Intuitively, I presume that the DIO pins corresponding channels and just go in ascending order, but I was wondering if someone could confirm this or point me in the right direction as to where I can identify this information.

  Of trial and error, I have deduced that my hypothesis is correct.

  Can someone please?
  =================
  I am running Oracle 10.2 on AIX 6.1.
  
  I do normally our production database backups on TSM, but this time, I need to copy the current production database to another server.
  
  Seems simple enough, right?
  
  Well, I put all my settings configuration RMAN 'disc' and created a new backup of the database of production on a local disk.
  Then I copied my game on the second backup server.
  
  I first started my nomount database, my DBID and restored my controlfile.
  No problem. That has worked well.
  
  Then, I tried several variants to restore the database.
  try simple "restore database".
  as well as to run {allocate channel c0 type disk; restore database, release the c0 channel} and then a few other ways.
  All attempts to give me the same exact errors:

• The user managed based backup Rman backup cold cold vs

  Hi all

  I just want to know the advantages and disadvantages for backup managed user cold and cold backup Rman.

  What is the best cold backup?

  Some some can help me?

  Thank you

  Cedric Joshi

  Hello

  Both are good only... If you took the clod backup (managed by the user), you can also do with RMAN catalog.

  I feel clod RMAN backup is good.

  Reason:

  ======

  ++ with RMAN you can avoid used used block, you can only backup used blocks

  ++ RMAN has its own compression algorithm

  ++ We also have the ability to assign multiple channels to parallelize the backup

• Cold DB RMAN backup & restore on the other server: best procedure?

  Hello

  A few days ago I did a cold backup of the GR 2 CARS DB 11 with the following commands:

  srvctl stop database d DBPOC

  RMAN target / < < EOF

  bootable media;

  run

  {

  assign the channel c1 type disc format ' / tmp/dump/coldBkp/%T_%d_DBID%I_s%s_p%p.bkp';

  backup of database TAG 'BKPCOLDDBPOCC' keep until 'sysdate + 1000';

  backup current controlfile TAG 'BKPCOLDDBPOC_CTL' keep until 'sysdate + 1000';

  backup spfile TAG 'BKPCOLDDBPOC_SPF' keep until 'sysdate + 1000';

  output channel c1;

  }

  SHUTDOWN IMMEDIATE;

  quit smoking;

  FO %

  srvctl start database-d DBPOC

  srvctl start service d DBPOC

  Then noticing that I need a copy of controlfile I also did:

  backup current controlfile copy format in ' / opt/dump/oracle/coldBkp/currentctlfile.ctl';

  He made a set of files in the file/tmp/dump/coldBkp system that I copied to another server, resembling:

  20130912_DBPOC_DBID23987234897_s371_p1.BKP... plus my currentctlfile.ctl.

  I copied everything on another machine in/tmp/rest, where the same structure of fs and ASM

  starts existed; then run the following commands to restore this DB on

  This new server:

  1 / set some env variables

  2 / cp initDBPOC.ora /opt/oracle/app/ora11g/product/11.2.0/db_1/dbs

  3 / sqlplus: Startup nomount pfile=/opt/oracle/app/ora11g/product/11.2.0/db_1/dbs/initDBPOC.ora

  4 / rman: restoring controlfile to ' / location/of/coldbackup/files/currentctlfile.ctl';

  5 / rman: sql 'alter database mount;

  6 / rman: catalogue start with "/ location/of/coldbackup/files";

  [Type here YES]

  7 / rman: restore the database;

  8 / sqlplus: recover database using backup controlfile until CANCEL;

  [immediately cancelled the first required archive log]

  9 / sqlplus: alter database open resetlogs;

  The procedure has worked.

  But I'm not happy with this, I thought I could have done with RMAN. However, I discovered

  e.g. a CONTROLFILE RECOVER with the HELP of BACKUP is not possible with RMAN etc etc.

  and I had to swith back to sqlplus, surprisingly.

  Am I missing orders RMAN should I used? Y at - it another way - more simple? -of

  perform this restore/recovery simple thanks to the RMAN utility only? Or is my error in backup

  the first place and I should have used other commands for backup?

  Thank you very much in advance for any advice you can give me...

  Kind regards
