  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;

• 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 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.

• Scripts for Oracle RAC

  Hi the CAR experts
  
  You have a script that can help us to control this node is in place, so we can take backup of the node2 when both nodes are rising. In the case that node2 downstairs
  We will have to take the backup on node 1, until the node 2 is running again.
  
  The configuration is the following:
  
  -AIX 6.1
  -Oracle RAC /ASM / RDBMS 11.1.0.7
  -We have a script rman.ksh that take backups.
  
  Please help us
  
  Thank you

  you guessed it Haggy!

  that\s the way you do.

  subsequently make a control one another when the command fails that verifies that the nodes are upward with the n olsnodes

  hopefyully this helps.

• 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.

• Installing Oracle RAC: Unix, Windows ASM nodes

  I have a question about the Oracle RAC configuration. I never did no prior installation RAC or ASM. Maybe a stupid question to some of you.
  
  Is it possible to install Oracle RAC with following options?
  
  2 node RAC with Sun Solaris
  Shared storage using ASM in Windows server
  
  Any additional information you can provide will be greatly appreciated.
  
  Thanks in advance

  In very simple terms, when using ASM, database server process read the CRUDE device and process DBWR write devices ROUGH containing tablespace information. With ASM, these processes simply ask ASM 'where the disk read/write. Therefore, ASM provides simply a "table of contents". (It is much more than that, but this seems to be a good way to start the discussion.)

  ASM MUST run on the same computer as the database instance that is to use it.

  In your scenario, the Windows computer may be Server iSCSI providing raw devices to Solaris machines. These devices would then be managed by ASM and reading/praav1s directly by database processes.

  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.

  Hi experts.

  Exadata, RAC DBMS EE 11.2.0.3.22, downstream from DB1 to DB2 replication on the same server.

  Maintenance of DB1 with DB rebound before a problem occurred.

  AMM on target DB.

  Original values:

  • memory_target - 6 GB
  • STREAMS_POOL_SIZE - 2GB

  ORA-04031: could not allocate 17859792 bytes of shared memory ('pool of water', 'unknown object', 'capture shared','ddltxt_knglddl' ") error trying to start the capture process.

  As in " " Note: 1521925.1 " ORA-4031 Troubleshooter" total memory and streams_pool_size rose:

  • memory_target - 2 GB plus 8 GB
  • STREAMS_POOL_SIZE - 128 M PLUS 2,125 GB. No possibility of increase of more than + 128 M

  Same error when starting capture.

  Investigation on MOS, shared from google on the capture of " " "ddltxt_knglddl","" gave practically nothing. "

  SR on created MOS. Nothing so far.

  Please advice. All thoughts are welcome.

  Thanks in advance for loans to help.

  Kind regards

  Igoroshka.

  Problem solved.

  Error reported a memory of 17859792 bytes. Increase the memory up to 12 GB, configuration of different sizes for streams_pool_size has not solved a problem.

  Analysis of pieces of free memory shown the biggest chunk of size in less than 17859792 bytes.

  After reset sga_max_size (or updated grater value than 8 GB) problem has been resolved. Looks like it was related to the size of granule. With size of granule sga_max_size > 8 GB has increased from 16 MB to 32 MB.

  HI -.

  In my view, this question was raised several years ago, but have not seen one work around other than to make adjustments at the level of the DBA for the shared memory pool settings.  There is no DBA on our team, and we plan to become one ;-)  I wonder if there is a way around this problem of minor user of OD or the SQL sys command-line interface?  I use the version of SQL * Developer and Oracle 12 c that comes on the machine virtual Lite of Big Data.

  An ORA-04031 error is an error of BMG; Limitation of memory in the component CMS such as pool, large pool, pool of java, of the stream is reached.

  You can do a lot of research in what is originally the ORA-04031, but you can also reduce or eliminate this error by increasing the size of the memory of the CMS, or using the automatic memory management (if you are not already using).

• Oracle RAC and replacement of equipment

  Hello world

  next year our Oracle RAC (hardware) servers will be is more supported. We have a 2 node RAC (SE) running on Linux 5. For you, what is the strategy easier (and safer) to replace the equipment:

  • Reinstall complete with database exports / imports.
  • Adding new nodes to the cluster with new servers and delete 'old' (but it seems that the same version of operating system is required in accordance with the documentation).
  • Clone of the cluster according to the Oracle documentation on news servers.

  Thank you for all your ideas. I googled a bit, but I've not found much info.

  Carlos.

  • Adding new nodes to the cluster with new servers and delete 'old' (but it seems that the same version of operating system is required in accordance with the documentation).

  It's what I strive for. If your time with new nodes in the cluster is short (less than 24 hours), and you stay on the same distribution (i.e. OL5 to OL7), then several times, this isn't a problem. If you still have concerns and do not feel comfortable with this recommendation, then I'll recommend another avenue. I often used it when I was doing something similar for the production system was too critical to take no risk.

  1. Up new servers in a cluster. You can even start with the version of grid Infrastructure more later/more big who can save a future update maybe you.
     1. It will take a new OCR and voting disk new configuration.
  2. Attach the storage shared on the new cluster. For a short period of time, you will have storage mounted to both old and new.
  3. Install the RDBMS software on the new cluster. Wear on all the config files you might need more... tnsnames.ora, sqlnet.ora, etc..
  4. When you are ready to drop the database on the old cluster, cutting on the new cluster.
  5. Use "srvctl database add" to add the database to the new cluster.
  6. Use 'srvctl add instance' to add the instances to the new cluster.
  7. (Optional but normally a good idea), use 'srvctl add service' to add services to the new cluster.
     1. Steps 5 and 6 above usually use the same name of db, same instance names, same service name.
  8. You now have the database running on the new hardware. Stop the old servers

  The only other sticking point would be handling the SCAN and traditional VIP. When I made this drive, I usually my network guy change the SCAN VIP and traditional dignitaries to be alias in DNS that point to the new VIP.

  If you do your homework and have everything ready to go, the downtime can be less than 15 minutes for this approach.

  See you soon,.
