  How can I add data file to an existing table on Oracle RAC ASM with no OMF? Thank you!

  Hello

  So I guess you have some files in ASM, see your first existing file structure

  Select file_name

  from dba_data_files;

  and to add to an existing table, the example below (even if you're better sticking with OMFs!)-is that what you are looking for?

  SQL > create tablespace TEST1

  2 datafile '+ DATA' size 1 M;

  Created tablespace.

  SQL > select file_name in dba_data_files;

  FILE_NAME

  --------------------------------------------------------------------------------

  Hello

  We intend to convert database of system 11.2.0.3 of ordinary/local file of the single node to node 2 RAC ASM.

  Please help me in the creation of the roadmap for the same thing.

  for example

• Oracle 11 g 2 11.2.0.3 Server install RAC (ASM) redhat linux 6 asmlib?

  I installed Oracle RAC (asm) on Red Hat Linux 4 and 5 without problems by using NFS and creating shared files and presented them to the DSO as devices without any problem.
  
  Now I meet with Oracle 11 g 2 ASM installation on Red Hat Linux 6.1 and the installation documentation is inaccuracies on how I can use shared NFS this empty asm files so that I can properly install the DSO. I understand that Oracle does not provide ASMLib for raw devices for Red Hat linux 6 going forward.
  
  I understand that asmlib must not be supported on Red Hat Linux 6 forward however I would appreciate information in support of the DSO on Red Hat Linux 6 using NFS share and create empty files with jj. This worked on Linux 5 and I'll try to find a solution.
  
  / sbin/scsi_id is used so that I understand. EXM/sbin/scsi_id-g u d < device empty file or dd >
  
  Trust setting of SCSI devices by adding the entry of /etc/scsi_id.config
  
  Rules UDEV advice would be appreciated.
  
  Since I use empty files to the server for ASM, using partprobe < path of the empty file? >?
  
  
  Thank you

  Hello

  If it comes to cluvfy in the program installation you indicating that your devices are not shared, contempt which (if you personally know that they are shared).
  This seems to be an annoying error with cluvfy, the shared disk check only works in specific circumstances...

  To be honest, I never saw him work properly, so I'm testing the devices 'sharedness' always myself (dd in on a node, dd on the other to see the results expected).

  If the error happens however at a date later (root.sh), then the devices are really not shared, or you have a permissions problem.

• 11.2.0.3 Pri RAC ASM with failover standby Post normal FileSys Active

  Made a move to the managed broker and not the file system Normal has the main role and the eve consists of two node rac asm. I want to switchback, i.e., former principal-> former role primary and Standby-> role of Eve.

  Hello

  According to the guidelines of your output, you can see log files waiting for new primary forward, but you haven't posted from sleep mode if you have set up the standby redo log files or not?
  This problem occurs only if there is an incorrect configuration , reconfigure then again by abandonment & recreating.

  Sleep mode: -.

• Need advice from configuration to the flash cache multi-node RAC/ASM

  We have a database of CARS to work two nodes. We install a new fusion 640 GB flash card in each node. The is a double card, so that it shows up as two devices: / dev/fioa and/dev/fiob on each node.
  We have created two groups of private drives, one on each node. The Group of disks on node 1 is '+ FLASHCACHE' and the disk on node 2 group is "+ FLASHCACHE2".
  
  We have not found specific examples of how to configure the parameters of the init for flashcache on RAC/ASM. We guess that we must do the following. If anyone would be critical and confirm or suggest something different, we would appreciate it very much!
  
  "prod1.db_flash_cache_file ='+ FLASHCACHE/flash1"
  prod2.dg_flash_cache_file = '+ FLASHCACHE2/flash2'
  * .db_flash_cache_size = 600G
  
  Thanks for any advice.
  
  Jim
  
  Published by: jimbev90 on January 5, 2012 08:18

  Hi Jim,.

  prod1.db_flash_cache_file='+FLASHCACHE/flash1'
  prod2.dg_flash_cache_file='+FLASHCACHE2/flash2'
  *.db_flash_cache_size=600G
  

  Your configuration is correct.

  Smart Flash Cache database is not shared across RAC nodes. It is private to each RAC instance. For this reason, each RAC instance must define its own local cache of flash file path. When the flash cache is managed by ASM, a separate diskgroup is necessary for each instance flash cache.

  You can use ALTER SYSTEM for db_flash_cache_size set to zero to disable the flash cache. Alternatively, you can use ALTER SYSTEM to deliver the flash cache to its original size to reactivate it.

• Oracle RAC ASM issues SQLLoader

  One of our clients wants to use Oracle RAC ASM for our application, I just want to know if there will be transactions of validation in two phases and SQL * Loader broadcasts in ASM.
  
  Oracle 10 g database is

  ASM works only at the level of the storage layer and has nothing to do with:
  -the distributed transactions
  -executable client that connects to the database instance: SQL * Loader, SQL * Plus, etc.

  RAC has also nothing to do with distributed transactions: a RAC database is a single database with multiple instances, but always a single database; There is no need to use distributed transactions because you have a RAC database.

• Oracle 10g RAC + ASM + Data Guard: Question on the new disk group.

  Hello
  
  One of our clients is to have Oracle 10 g RAC + ASM + Data Guard. Database is the disk DATA_DG1 group and FRA is on FLASH_DG1. Data Guard is a single instance on ASM.
  
  To add more space, we can create another disc of the Group DATA_DG2 on Prod ASM and Data Guard ASM env, replication continues without any problem. Will be archiving logs shipped to the second disk DATA_DG2 group and applied without any configuration changes?
  
  Rgds,

  Yes, it sounds great.

  You should be fine with the implementation of these measures and the dataguard should continue on as usual.

  Just make sure that you are dealing with a physical standby that has not the conerts file name defined.

  Your paging file must be at least as big as your physical ram, or in your case specific at least 9 GB or larger.  The value of your swap 32 GB if you plan to use the AMM but I wouldn't use it AMM because Oracle does not support on Solaris.  Supported only for the ASM instance and not the databases.

• Copy the RAC ASM RMAN backups

  Hi, I have a database (RHEL 5.8) RAC 2 nodes with shared ASM storage. RMAN makes daily backups on this ASM storage too. How could copy backups of the ASM to another place? I use version 10 gr 2 db, and there is no 'cp' command in asmcmd.

  How could copy backups of the ASM to another place? I use version 10 gr 2 db, and there is no 'cp' command in asmcmd.

  You can use RMAN to do it.

  Use the command

  RMAN>  backup backupset from ... format '' ;

• Saving OCR for Non-RAC ASM

  Hi gurus,
  
  Need your help for below question.
  We have no cars 11 GR 2 DB with ASM RHEL 6.2. When I am trying to take ocr backup, below errors are encountered.
  
  [grid@remedy-ebu-test-db1 cure-EBU-test-db1] $ sudo /u01/app/grid/product/11.2.0/grid/bin/ocrconfig - manualbackup
  PROT-1: failed to initialize ocrconfig
  PROC-32: lending of Cluster on the local node service does not work e-mail [gipcretConnectionRefused] error [29]
  
  In addition,
  
  (1) should we backup OCR for instances Non-RAC? I know that backup voting disk are not necessary but what about OCR. Since there is no cluster that not involved how ASM and DB will remain intact.
  (2) in addition, there is no automatic OCR backup available? According to the MOS, GR 11, 2 takes automatic backups of OCR.
  
  Kind regards
  Nikhil Mehta.

  If you do not have BECAUSE you have Oracle Local Registry (OLR) instead of Oracle Cluster Registry (OCR).

  To try OLR backup:

  ocrconfig -local -manualbackup
  

  To list the existing backups OLR try:

  ocrconfig -local -showbackup
  

• Reboot node RAC, ASM/crs all restarted but the database

  Version of the OS: linux redhat 5
  DB version: 11.2.0.3
  2 node RAC
  
  He used everything works well. I just configured and implemented hugepages lately and boxes of restarted.
  
  everything else like ASM, listener, crs all restarted, but db did not.
  
  What should I check to ensure that the work of automatic restart of the oracle?
  Thank you.

  Hello

  If you stopped the db with "srvctl stop database", then this is recorded in the OCR. And restart the clusterstack it does not restart the database (since you said clusterware, he should be arrested).

  Works as expected.

  If you want the cluster to start over, database simply stop the clusterware (crsctl stop crs).

  Why not :) What is the version of db? You can also use ASM on stand-alone server. For details pelase see what Hussein posted snoussi.

  Yes. You will need to first stop the battery Oracle Clusterware on the node on which you must stop the Oracle ASM instance.
  Use "crsctl stop cluster node_name - n" or "crsctl stop crs" for this purpose.

  Since you are using OCR and VOTING DISK on ASM, it is not possible only stop ASM and keep cluster running.
