• How to create a no - ASM ASM DR 2 nodes (OMF)

  All,

  I have a need to create a DR on a virtual machine to a single node to a DB of RAC 2 nodes that would be used only as a reporting env. Unfortunately, Google has not given results in this direction. When I read the docs of the oracle, it seems that this is not possible. Someone at - it created such a DR and has steps for him?

  References that are in conflict:

  Ref 1: If data source files use OMF, you cannot rename using DB_FILE_NAME_CONVERT . "Use of storage no-ASM" address details and options of data managed by OMF files

  
  

  Ref 2:
  

  • You use the LOG_FILE_NAME_CONVERT parameter to name the standby redo logs if the main and backup databases use different naming conventions for the log files.
  • You cannot use the SET NEWNAME or CONFIGURE AUXNAME commands to rename the standby redo log files.
  • You cannot use the LOGFILE section of the DUPLICATE command to specify the names of files to the standby redo log files.

  As I understand it, your question is mainly with primary OMF and OMF - not on the physical database. If so, then the show a duplicate RMAN by defining "db_file_name_convert" isn't a valid option. Pending reason - this setting on the database, and then run the duplicate would lead to the creation of OMF files on the eve.

  The best approach would be to use the "set newname for data file" (if the number of data file is less) or you can go with the 'set newname for the database' option too.

  Happens to your other concern about how the day before would work if 'db_file_name_convert' is not defined. It's true, if a data file is added on the primary (I'm talking about the OMF files), the file would not be reflected or automatically created on the standby database (even if you set standby_file_management true) as 'db_file_name_convert' is not defined. In this case, manual intervention is necessary. An entry could be created for the newly added 'no FILE NAME"data file on the database pending and which will have to be renamed according to the system non - OMF file you want. Thus, overall, to solve OMF datafiles on the primary database no omf files of the database data pending, you need manual intervention.

  You can see the messages of this kind in the alerts log:

  WARNING: OMF is enabled on this database. Creating a physical

  standby controlfile, when OMF is enabled on the primary

  database, requires manual intervention by RMAN to solve the OMF

  the data file paths.

  Even if it were possible to store these files in ASM using XDB, you wouldn't be able to see without ASM out back for display.

  You'd better hide files by setting their permissions file or by using access control lists.

• create dblink to asm of the RDBMS instance

  Have a metric solution on a database that queries all RDBMS instances for different indicators, applications, and administration and reported to the users/admins via apex.

  You want to use to report the news datagroup ASM but need a dblink to ASM to run the query of the RDBMS instance, is it possible?   I can check it in EM or run a query on the host itself or the same sqlplus via sysasm connection but would like to do if possible a procedure, but would need a link

  You can do that, because a link needs a dictionary of data at the other end to authenticate.

  I did it using Java in the RDBMS instance to connect to the instance of the ASM, and then run any query/DML/DDL. I can't give you the (intellectual property) code, but you could contact my employer (details in my profile) to see if he would release it.

• ASM Diskgroup existing disks

  Hello
  Oracle RDBMS version 11.2.0.3.0
  OS: OEL 6.3
  Stand-alone server of the grid Infrastructure.
  MY question: I want to connect existing disks to ASM instance. What commands to create new disks existing diskgroup using without erasing the data on disks?

  Hello
  My recommendation is to create the ASM using ASCMA instance.

  Because the step below is valid only up to 11.1 or less, for 11.2 is missing a few extra steps.

  Now the steps for manual creation of DSO;

  1. create the file password for manually creating an ASM instance.
  orapwd file = $ORACLE_HOME/dbs/orapw + ASM Password123 = 5 entries = password

  In this way the user ASMSNMP will not be created and you must manually assigns a role SYSASM to the SYS user. ASMCA do automatically.

  2. create the needed directories:

  mkdir Pei $ORACLE_BASE/admin / + ASM
  CD $ORACLE_BASE/admin / + ASM
  mkdir bdump
  mkdir udump
  mkdir cdump
  mkdir pfile

  These directories are obsolete on 11.2, now Oracle use ADR to store logs.

  3. create the file init + ASM.ora under the $ORACLE_HOME/dbs:

  asm_diskgroups = 'DATA', 'FRA '.
  asm_diskstring = "/ dev/oracleasm/discs / *'"
  background_dump_dest ='/ u01/app/admin / + ASM/bdump "
  core_dump_dest ='/ u01/app/admin / + ASM/cdump '
  instance_type = "asm".
  LARGE_POOL_SIZE = 12 M
  user_dump_dest ='/ u01/app/admin / + ASM/udump '

  ASMCA value target memory at least 272 M

  4 - export ORACLE_SID = + ASM
  Instance ASM 5-start in editing mode:

  sqlplus / as sysasm
  Create spfile from pfile;
  Startup mount
  Show disc setting

  6 - Mount starts;

  change fra diskgroup Steed;
  change the data diskgroup medium;

  Missing a few steps here.

  ASMCA will activate/configure "ora.asm" (by adding the SPFILE and some PARAMETERS on OLR) resources and all dependent resources and create DISKGROUP resources.
  If you do not have config, ASM will be not started/stoped/restarted automatically.

  Once again... Is recommended to create an ASM Instance using ASMCA and a SMALL Lun (1 GB) to store only the ASM SPFILE when creating and then just get the other DISKGROUP.

  When you activate your database or add the DISKGROUP resources on Oracle Restart, and ASM must exist to work properly

  Have you seen my 2nd answer where I asked that you are sure that 4 M size to THE East actually possible in 10g ASM (10203 your version) as far as I KNOW, this has begun to 11.1 from which can reach the size of the AU to a default value of 1 M 64 M.

• ASM Diskgroup with 1 disk? Is this possible?

  ^^
  I saw once on the google site a syntax as above. I was under the assumption that, for alteast disks 2 ASM are required (assuming normal redundancy); But here we can see one disc is defined.
  
  Sorry, I don't have an ASM Setup to test this, so would you need advice from people.

  By default, ASM tries to create a normal redundancy disk group. Therefore, he expected to have at least 2 groups of disks.
  But yes, even with one disk, you can create a disk group, but you must expressly state that it will be external redundancy.

  I can create a diskgroup (redundancy = normal) using DBCA, but similar operation cannot perform through command line.

  DB version: 10.2.0.5 on RHEL

  Shows your screenshot of the ASMCA you assign disk/dev/raw/raw5 in FailGroup FG1 and disk/dev/raw/raw6 in FailGroup FG2 - two * different * FailGroups. Each disc is in a separate FailGroup.

  Your Interactive SQL command specifies only 1 FailGroup when there is to specify two FailGroups.

• Create the ASM disk groups instance is not found

  
  Hello

  I just started to learn Oracle, very inexperienced database in Oracle.

  I have a problem to create an ASM instance. My environment is SUSe Linux Enterprise 11 64-bit, I am creating an instance ASM 11.2.0

  1. when I create ASM instance, I couldn't find ASM disks, if an ASM Instance could not be created.

  2. when I search on the internet on the creation of the ASM disk, it seems that I need to connect to the instance ASM as ASMSYS, but I have not an ASM instance is runing so ASM DISK groups has not can be created.

  I feel that I'm at an impasse.

  Could someone help me?

  Thank you.

  You may need to configure the udev subsystem to set permissions of the device and configure the parameter diskstring ASM or install Linux ASMLib, that supports both and more.  In any case, you will need to provide more details and probably do some research to learn more about the basic concepts. To install Oracle ASM is not click and play.

• What is the correct procedure to abandon diskgroup asm is rac?

  Hello
  
  I would like to table a diskgroup in asm to the CCR? What is the correct procedure?

  3. after droping command, is there any other procedures to be done?

  Thank you very much. Oracle 10.2, if I unmount the diskgroup, I want something offline, or what is the procedure before changing disgroup xxx disassemble?

  You MUST remove (using DBCA) or move (using RMAN) all databases stored on the diskgroup (if exists) before giving up DISKGROUP.
  (1) check if there are any database using the DISKGROUP.
  The query above must return no rows.

  SQL>  SELECT D.NAME,C.INSTANCE_NAME,C.DB_NAME,C.STATUS
       FROM GV$ASM_DISKGROUP D , GV$ASM_CLIENT C
       WHERE D.GROUP_NUMBER=C.GROUP_NUMBER
       AND D.NAME = '';  
  
  no rows selected
  

  If the above query returns rows you remove and stop must all first trial or move the database to an another DISKGROUP.

  (2) remove the Diskgroup all instances of ASM, except one.

  ALTER DISKGROUP  DISMOUNT;
  

  (3) decline diskgroup of the ASM instance, that the diskgroup is still mounted

  DROP DISKGROUP ; -- If no files on DISKGROUP
  DROP DISKGROUP  INCLUDING CONTENTS; - If exits files on DISKGROUP
  

  Just it.
