ASM to the question of the NO - ASM

• Questions of the ASM

  Hi, I have several questions here. I managed the migration of instance ASM to ASM instance to be autonomous and RAC environment.

  Now I meet this task to migrate an environment 11 GR 1 very old material on Sun solaris 5.10 to 5.11 Oracle version 11.2.0.3.

  I have some questions I need to ask gurus here.

  (1) we got okay to use restart with stand-alone server using ASM oracle management.

  Current context, all files of data on local disks of/U02 - u10.

  If during migration, we will create an expectation of prod db (11 GR 1 material that all files located on a local system without OMF) and instant upgrade standby then this eve upgraded to the new ASM Oracle system restart.

  So my questions are: a). I guess I'll create this same exact main expectation that current prod environment, means no OMF no ASM. then upgrade.

  (b) target (11 GR 2) then I'll install oracle asm/restart on the area.  now, how do I know that I can use OMF, and files from u02 - 10 went to the diskgroup?

  (2) the storage people have no experience of ASM lun. For the autonomous zone, is that they have just to introducing the raw LUN?  then I left Oracle asm discover?  What should I use UDEV (I think it's for CARS) to manage those LUNs? What is the official way to do it? any docs? LUN will be on emc storage.

  Thank you much in advance.

  Yes, theoretically you must Restart Oracle and ASM - c-d. Grid infrastructure - MORE the Oracle_Home of RDBMS.

• Basic questions about the installation of ASM

  I can't find definitive answers to the following. Let me try here. I want to build a server Linux, RDBMS 11.2.0.3, running with the ASM. It's just the prototype server, in our conversion of Oracle 11 g on AIX without ASM on Oracle 11 g on Linux with the ASM.
  
  I have an Oracle VM already running cluster and built a number of virtual machines in models, and everything works fine. Now I am installing DSO, have failed repeatedly. Maybe I'm doing something fundamentally wrong. Here are two questions:
  
  1. is it true that the only (reasonable) to install DSO is to install the product called "grid Infrastructure? As far as I know, the answer is 'yes '. But GI seems to be so much more than ASM, although I don't think I want or need. Is there an easier way to get ASM?
  
  2. the matrix certification swear that grid 11.2.0.3 Infrastructure is certified on Oracle Linux 6. (1) I can still see a lot of posts on OTN and elsewhere on the net that say it is NOT supported and that there are has mant problems in get the installation works, and (2) I have tried to install it on OEL 6 and can't get the installer to finish. Specifically, the root.sh script fails with "ohasd failed to start... '. ». Before further my installation problems, I want to just make sure: If this installation of OEL 6?

  ASM is a feature of the Oracle Grid infrastructure Installation. So you will need to install IM using ASM.

  There is a GI installation which can be installed and configured in two different directions. For a Cluster or for a standalone.

  This option must be selected during installation.

  The installation of GI for a standalone is called Oracle Restart.

  GI for a Cluster installation is called Oracle Clusterware.

  The two options above have the particularity of the DSO.

  2. the matrix certification swear that grid 11.2.0.3 Infrastructure is certified on Oracle Linux 6. (1) I can still see a lot of posts on OTN and elsewhere on the net that say it is NOT supported and that there are has mant problems in get the installation works, and (2) I have tried to install it on OEL 6 and can't get the installer to finish.

  A lot of users here OTN tried installing Grid Infrastructure on RHEL6/OEL6 when it is not certified. Many questions appear.

  When it has been certified by Oracle, it remains several notes on MOS that will help you follow the main steps for a successful installation.

  I think you should use OEL 6, since Oracle Linux 6 has been certified by Oracle Corporation, you have all the support on this product.

• Question of the ASM

  Hello
  
  I'll put up a 11.2.0.3 new install and I have a problem in my hands a little bit.
  
  While doing the installation, I created the asm on a partition disk in:

  oracleasm createdisk DATA /dev/sdb2

  Now, after rebooting, it may be the case when my score is not identified as/dev/sdb2 more instance cannot find the disc, so I need to tag it with something like

  e2label <partition> <labelname>

  to ensure consistent names after a reboot and my instance ASM will not fail
  
  My question is, can I I "remap" the ASM/dev/sdb2 < labelname > disc without having to recreate all over again? If so, how?
  
  Thank you

  ASM autonomous, that is right.

  just now, I am from sracth, comes to complete installation of oel6 and create the partitions with fdisk on my raid1 + 0
  one that I have already formatted with ext3 and im moving the installers to the server to start

  Any guide you know I can't go through?

  Have not yet installed oracleasm.

  The next steps so far are:
  -Once all the installation on the server programs I'm good to go with oracleasm
  --> Create disc on an unformatted partition/dev/sdb2
  --> install grid
  --> create diskgroup
  --> install 11 GR 2
  --> instance to create

  DO NOT use oracleasm - as I have said, it is expected to be close to retirement. If you don't want to be related to it.

  Make sure that the device has the appropriate permissions before you start.
  In the installation program, select ASM for OCR. in the lower right corner to select CHANGE DISKSTRING and configured to point to/dev/sd * and he sees only one with the correct permissions. It will ask you the name of diskgroup, and you select the sdb2 with REDUNDANCY EXTERNAL device. It will automatically load the initial configuration. Watch the udev.config to find out how to set permissions on startup

  I don't usually promote other websites, but this looks like a good start on how to correctly configure udev...

• question about the operation of the ASM

  Hello
  
  I use as storage oracle 11 GR 1 option matter and ASM. the sys user is Administrator of the ASM, but I am not able to access ASM instance with the sys user. If I didn't know oracle, then I have access instance asm, asm dg operation etc, I thought that ASM admin is one who can perform an operation on the instance asm and asm dg etc that I should always user use 'oracle' for the operation of the DSO. cant I use user "sys" to it. Please share your opinion on this.
  
  
  Thanks for your help,

  user11305560 wrote:
  I export ORACLE_SID variable. But if su do oracle then only i can do surgery ASM.

  Yes, and that's because the user of the OS who need all permissions to administer the instance ASM 'oracle '.

  If I didn't know sys, then it does not allow me to do. sys is a Director of the DSO, so I thought that it should also be able to perform the operation ASM.

  Yes, it's because "sys" is (in your case is obviously) user OS that do not need all permissions to administer the ASM instance.
  Then, when you're OS user oracle, unlike when you're OS user sys, you are able to connect to the DSO with the SYS user database

  My question is, can only the user oracle ASM operations do.

  Each user of the operating system with appropriate permissions can do

  Thank you.

• Double LOG_ARCHIVE_DEST places. One is FRA the other is regular ASM no disc. Cleaning question

  Double LOG_ARCHIVE_DEST places. One is FRA the other is regular ASM no disc.

  Oracle does not recommend manually delete logs archiving of the FRA, but rather let the FRA cleaning place based on archive political log deletion and backup retention policy, which works perfectly, but now that we have newspapers archive mirrored on a location not FRA to clean archives connects to this place with RMAN. How can we clean up the FRA NO cleaning is not the FRA through rman?

  Just use:

  RMAN > BACKUP AS ARCHIVELOG '+ DB_FRA/dborcl/archivelog/%' ENTRY DELETE;

  With the ENTRY to be REMOVED, RMAN only deletes the specific copy of the newspaper of archived recovery chosen for the backup set.

  REMOVE all THE ENTRIES, RMAN deletes each file backed up log redo archived log destinations archiving.

  It backs up from a specific location and delete it after backup.

• ASM - no to the question of the ASM DB_FILE_NAME_CONVERT

  Nice day. I'll put up a Data Guard environment in which existing primary is no - ASM and the new auxiliary will be ASM. I am trying to determine the correct entries for the parameters DB_FILE_NAME_CONVERT and LOG_FILE_NAME_CONVERT. can someone please tell me if I am following the right path?

  On the primary (non - ASM), I'm going in SQLPLUS:

  SQL> select file_name from dba_data_files;
  FILE_NAME
  ------------------------------------------------------------------------
  /u03/app/oracle/oradata/prodDB/system01.dbf
  /u03/app/oracle/oradata/prodDB/sysaux01.dbf
  etc...
  
  

  SQL> select member from v$logfile;
  MEMBER
  ------------------------------------------------------------------------
  /u02/app/oracle/redologs/prodDB/redo03a.rdo
  /u03/app/oracle/redologs/prodDB/redo03b.rdo
  /u02/app/oracle/redologs/prodDB/redo02a.rdo
  /u03/app/oracle/redologs/prodDB/redo02b.rdo
  etc...
  
  
  

  My expectation is a new facility with ASM and Oracle 11r2 software installation so there not necessarily all the files yet, but in addition the system drive, it has 4 discs. Disk1 and DISK2 are in the disk group ASM 'DATA' and DISK3 and DISK4 are in the "FRA" ASM disk group

  Is below what would look like my settings?

  Elementary school:

  DB_FILE_NAME_CONVERT ='+ DATA / prodDB / ',' / u03/app/oracle/oradata/prodDB /'

  LOG_FILE_NAME_CONVERT ='+ FRA/prodDB / ',' / u02/app/oracle/redologs/prodDB / ',' + FRA/prodDB / ',' / u03/app/oracle/redologs /'

  And on standby to invert the inputs?

  Finally, if I were to add a third guard database server in this situation, I just fired on another comma and add a third entry in the above settings?

  Elementary school:

  DB_FILE_NAME_CONVERT ='+ DATA / prodDB / ',' / u03/app/oracle/oradata/prodDB /'

  LOG_FILE_NAME_CONVERT ='+ FRA/prodDB / ',' / u02/app/oracle/redologs/prodDB / ',' + FRA/prodDB / ',' / u03/app/oracle/redologs /'

  When the primary is on no - asm and pilot light is on ASM, then the first string, always belongs to the primary and then the following string is of course the day before... If your data files located in several locations, then you can add more as needed.

  An example below, you can mention '+ DATA' instead of '+ DATA/prodDB' If you use OMF and Oracle takes the directory based on the DB_UNIQUE_NAME you define, then disk group can do your job.

  DB_FILE_NAME_CONVERT = "/ u03/app/oracle/oradata/prodDB ', '+ DATA ';

  The same applicable to the LOG_FILE_NAME_CONVERT as well.

• Two questions on ASM for the Installation of the grid

  Version of grid Infrastructure: 11.2.0.3

  Question1.

• The ASM diskgroup in exadata space question

  All,
  
  I have an environment exadata 1 CCR node with 3 knots of strorage.
  
  My RECO ASM diskgroup is constantly showing the problems of space... Always higher than 80%.
  
  I just want to get a Board if I can remove mirroring and recover the space... Even though I know that the result of the deletion of the mirroring...
  
  Can I reduce the diskgroup RECO and create an another diskgroup?
  
  I want just a few ideas to do this without great risk involved...

  You may want to consider these MOS notes for more information on resizing the griddisks:
  Resize diskgroup without downtime to Exadata (Doc ID 1272569.1)
  How to resize the disk drive/grid ASM in environment Exadata (Doc ID 1245494.1)

  As others have mentioned, there is no way to change the level of redundancy in ASM, so you need to delete and re-create the diskgroup if you want to change to redundancy. We strongly discourage the use of EXTERNAL with Exadata redundancy.

  Hi Garry,

  1. Yes, it should start automatically. You have defined all variables before you start the installation?

  2. the variable ORACLE_HOME must be set to the location of GRID_HOME for the user environment of GRID and the location of ORACLE_HOME for the oracle user.

  Kind regards.

• 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.

• Question about the use of size mixed with ASM disk groups

  I support a RAC 10 g 10.2.0.3 running and using ASM cluster. We currently have a group of data disks, which is 600 GB in size, consisting of 3 individual raw disk 200 GB devices. The RAC cluster runs on a server pSeries IBM using AIX 5.3
  
  I need to add more space, but the system administrator can give me only 100 GB in the new raw device. What will be the impact, if any, the addition of this feature of smaller crude disk in the same data ASM disk group? I understand that ASM is trying to "balance" the general use of each raw device. ASM still works very well, or will he constantly try to rebalance the disk group because the a raw device is only half of the other three? Any help and advice would be greatly appreciated. Thank you!

  It works, I do the same thing in a production database. What happens is, asm will distribute data on the size of the disks. 200 GB drives will get two times more data than the 100 GB drive. The downside is that it will also result in an unequal distribution of the IOPS / s: adults discs will be achieved more often.

• Questions of the ASM WMA

  Hello
  
  I now have the weird behavior here. In other words, it intrigues me.
  
  I have only one instance of Oracle 11.1.0.7 ASM on an IBM AIX 5.3 TL 06 Server
  There no database yet configured to use this ASM instance as storage device.
  
  What I see here, is that any less than 90 M SGA_MAX_SIZE setting causes an error. SGA_MAX_SIZE 90 M is the absolute minimum on this server.
  
  Now the "problem":
  
  At the urging of normal-that is to say no ASM - AFAIK sga_max_size is the absolute maximum while sga_target can be adjusted upward for this size
  
  On my instance ASM every time I put only sga_max_size = 90M the instance starts as expected:
  SQL > startup nomount
  ASM instance started
  
  System Global area * 96026624 * bytes
  Bytes of size 2151248 fixed
  68709552 variable size bytes
  ASM Cache 25165824 bytes
  SQL >
  
  Now when I put SGA_TARGET also worth something strange happens.
  First of all only in memory:
  SQL > alter system set sga_target scope = 90M = memory;
  
  Modified system.
  
  SQL > show sga
  
  System Global area * 96026624 * bytes
  Bytes of size 2151248 fixed
  68709552 variable size bytes
  ASM Cache 25165824 bytes
  SQL >
  
  Looks OK, it isn't?
  
  Now in the SPFILE:
  
  SQL > alter system set sga_target = 90M scope = spfile;
  
  Modified system.
  
  SQL > shutdown immediate
  ORA-15100: invalid name or missing diskgroup
  
  Shutdown ASM instance
  SQL > startup nomount;
  ASM instance started
  
  Total System Global Area 162856960 bytes
  Bytes of size 2151848 fixed
  135539288 variable size bytes
  ASM Cache 25165824 bytes
  
  Now why the total size of the SGA has increased to 156M.
  
  It's even more bizarre when I Remove the SGA_MAX_SIZE of the spfile and only set SGA_TARGET = 90 M. then
  SQL > startup nomount;
  ASM instance started
  
  Total System Global Area 283930624 bytes
  Bytes of size 2153056 fixed
  256611744 variable size bytes
  ASM Cache 25165824 bytes
  SQL >
  
  
  Please note: the spfile sga_max_size removal is performed by recreating of a pfile
  
  Someone at - it a suggestion in how to set the parameters of the AMM for an ASM instance so it behaves as expected, or at least as a database of "normal"?
  
  
  Thank you

  The answer is quite simple - ASM is currently not using the automatic Oracle 10 g database memory management feature. There was significant optimizations in GR 11, 1 material with regard to memory management, so there is no
  you will need to set the parameters of the SGA in GR 11, 1 material. ASM now operates the MEMORY_TARGET parameter and
  the default value of 256 MB is more than enough for the ASM instance. The management of processes (ASM)
  has also been optimized, so the setting process also should not be defined in GR 11, 1 material.

  You can reffer metalink note 265633.1 - there is a pdf document and that describes what needs to be set and what is not taken in charge.
