• ASM cluster file system and df h

  Hello Oracle Community,

  I was wondering why my ASM cluster file system showing 96% (25 GB free) used, even if I moved and deleted (200 GB +) I still exports datapump see 96%.  When running the - h - max-depth = 1, it shows the correct value of 216 GB used.  But this isn't until hours later, when you run df h even once, I finally see the free space on the drive, which I was expecting.  The system is a RAC run red hat 6.5 with Oracle SE 11.2.0.4.

  [shared me@db02] $ - h - max-depth = 1
  from: cannot read directory '. / lost + found ': Permission denied
  64 k. / lost + found
  1.9 G. / datapump
  129. M / temp

  [shared me@db02] $ df-h

  / dev/ASM/acfsvol-287 548 G 524 G 25 G 96% / u05/shared

  Could someone please clarify why this is happening.

• Is Dell's FluidFS a cluster file system?

  I ask because I have several servers that must write to the same iSCSI target.  If I understand correctly what could mean the blocking issues and corruption.  This is fixed by an updated on the cluster file system.  I see a lot of mention of the word 'cluster' with the FS7600, but I don't know if Dell's FluidFS is a system of files updated on the cluster or if the FS7600 is somehow a cluster os in general.

  Can the FS7600 help me in my concerns about corruption, or do I still need to have an another clustered file system.

  Yes.  It is designed from day one to be a cluster.  You don't have to worry a NAS accidental head on the other.

  When you use the FS7600 that isn't an iSCSI target, it's a network share.  Either through NFS or CIFS.  What are the multiple systems can connect to.

  If you create a volume iSCSI on the table itself, then your hosts the need to run a cluster file system up-to-date, it's true.

  Thank you

  OK, so you're not do backups at all.

  In other words, that your only option is to reload the database from the most recent export. This means that you going to LOSE data at the time of the last export, up to the current moment in time.

  As others have said, I'll say it again: export is NOT a backup strategy valid! You must run in archivelog, backup your database regularly mode (using the RMAN backup) and backup and Save (once again, with RMAN) all archivelogs generated between backups!

  But it is what it is. You have only export you took. So, you need to work with what you have. Given that corruption is file #1, which is the SYSTEM tablespace datafile, your only option is to drop and re-create the database, and then import your latest export.

  When you have done this, and you have a working database once again, go back and set ŒUVRE a REAL STRATEGY of BACKUP! Use RMAN, place the database in archivelog mode. Do not hesitate!

  Hope that helps,

  Hello

  If the files on disc with voting rights are in a disk group, know that groups of disks with files Oracle Clusterware (OCR and voting disk files) have a more minimal number of failure than other groups of disks.
  If you create a group of records as part of the installation in order to install the OCR and files on the drive to vote, then the installation program requires that you create these files on a disk group with at least 2 GB of free space.

  A lack of quorum group is a special type of the failure group and these groups of failed disks contain no user data. A group of lack of quorum is not considered when determining the requirements of the redundancy for storage of user data. However, a lack of quorum group account when mounting a disk group.

  For the Oracle Clusterware installation, you must also add the additional disk space for Oracle ASM metadata. You can use the following formula to calculate the disk space required (in MB) for the OCR and voting disk files and metadata from Oracle ASM:

  total = [2 * ausize * discs] + [redundancy * (ausize * (nodes * (+ 1) + 30 clients) + (64 * nodes) + 533)]

  Where:

  redundancy = number of mirrors: external = 1, normal = 2, high = 3.

  ausize = size in megabytes metadata.

  nodes = number of cluster nodes.

  clients - the number of instances of database for each node.

  drives - number of disks in the disk group.

  See the link below for more details...

• not generating the trace for rdf report by oracle apps file

  Hi all
  
  
  in fact, we aim to generate trace file for reports and a convert to text file using tkprof by simultaneous program unix shell script submit using fnd_request.submit_request in another program of concurrent proceedings. but all the reports that are created by using pl/sql generates the trace file, but rdf report does not trace file.
  
  Report generator Oracle 6i is used
  
  Oracle application is 11i
  
  List of measures are being taken to get the trace file are
  1.SRW. USER_EXIT (' FND SRWINIT' "); before the release of report
  2SRW. USER_EXIT ("FND SRWEXIT'"); in after the report
  
  another of the measures which are followed
  SRW.do_sql ("alter session set SQL_TRACE = TRUE'"); before release of the report
  SRW.do_sql ("alter session set SQL_TRACE = FALSE'"); in after the report
  
  above, said steps are done, but still it does not arouse any trace file
  
  same oracle_process is null
  
  Select oracle_process_id from the fnd_concurrent_requests where request_id

  Add the following line before the outbreak of report
  SRW. DO_SQL ("alter session set events = tracefile_identifier" trace 10046 name context forever, level 4 "=" REPORT ' ")

  Trace stops automatically when the report closes.

  In addition, what program submits the script fnd_request.submit_request... shell / pl/sql procedure?

  you initialize apps FND_GLOBAL. APPS_INITIALIZE before submit_request of shooting?

  Make a DNF: active Log Debug = Yes and check the table of fnd_log_messages

• Why not place the Oracle data files on local disks

  Hi, I want to ask a fundamental question.
  
  Almost any Oracle installation I've seen, data files have been placed on Mount points, disk etc..
  
  Is there a reason for this? Why no one does place for local disks oracle data files? I couldn't find the answer on the installation guide
  
  I ask this because I will install oracle (10g) on vmware and trying to decide whether to put data on the vmdk (virtual computer local disk) files...
  Is - this recommended? If not, why it is recommended to put data files to a disc of fixation for point/external etc..
  
  
  Thanks in advance

  Hello

  People store data files on separate disks
  (1) bettter performance
  (2) the data can be in a centralized storage
  (3) if the OS crashes always files are safe
  (4) configurable with raid options
  (5) hot Swapping
  (6) easily can add additional storage

• Change the Cluster File System-> ASM storage mechanism? Options?

  Currently I have set up RAC 11g to the following address:
  
  * cluster of 11g two knots on Red Hat Linux 64-bit on Oracle VM Server 2.1.2 E5
  * a node 11g in Oracle VM used for NFS share for the two nodes of Oracle on Red Hat Linux E5 64bits
  
  Could I take a node 11g in Oracle VM and reinstalling Red Hat Linux and allows to create ASM storage? and how could it be shared for two other nodes? Thank you

  Hello

  Ricardo brings a good point. I understand that you currently have an HR / node Oracle VM running as a server NFS, NFS to provide storage for RAC database.

  Given that you have no support for your system - because it's a test system - and you have your 2 node RAC running on the same physical machine (same Oracle VM host), then you can use the local storage of the physical server as a base for ASM. If there are not enough local storage on your system, this could be a problem. In all cases, instances of ASM should run in the Oracle VM hosting the RAC instances.

  Please, take a look at the updated recently in the CANTON "[Oracle Real Application Clusters environments Oracle VM |]» http://www.Oracle.com/technology/products/database/Clusterware/PDF/oracle_rac_in_oracle_vm_environments.PDF] ", which has a section on the storage configuration update.

  Thank you for choosing Oracle VM on VMware!

  Hope that helps. Thank you

• Backup Oracle database files

  Quick question... If I put the data base oracle in Archivelog mode, can I use such as Symantec or ARCServe Backup software to back up the directory where all database files to include archiveredo newspapers? It would be an acceptable means of backup of the database without using RMAN? Reason I ask is if incase we have a total breakdown of the system, I would like to rebuild the server, install Oracle with the same instance name and installation directory, and simply restore the database files and be operational. Thanks to produce for your help.

  The right way to achieve your goal would be to use rman to back up the database, and then use other tools to backup the backups that have been created by rman.

  Have you read that anything posted here? All you need to do is

  alter system set AUDIT_TRAIL=DB scope=spfile;
  shutdown immediate

  Question: Why not use a pfile file?
  Answer: Edit a file pfile is one of several unnecessary steps when you already use a spfile

  Question: why specify scope = spfile instead of other options for "scope".
  Answer: this particular setting is "unchangeable." Please see the documentation on this parameter in the reference manual. The "editable" property is shown as 'NO '. Perhaps the use of the term 'editable' oracle is a little misleading. This means that the parameter is not dynamically editable. Therefore, the scope of the ALTER SYSTEM cannot for the spfile, memory (the running instance).

  Question: Why can I restart the database?
  Answer: even once, this particular parm is not dynamic. Therefore, it requires a restart of the database to pick up the change after the spfile has been changed through the ALTER SYSTEM... SCOPE = SPFILE command.

• P2V microsoft cluster (file) with shared PV220s (SCSi) storage

  Hi guys

  I'm quite new in the VMWARE world. So please forgive my ignorance. If it's my third message in the last 2 days.

  Scenario: basically, we have a MS cluster running on two windows (our file server) server that is attached to the DELL PV220s matrix raid (scsi) with 11 drive running raid 5 config... Now it of almost complete @ 1 TB and also will be out of warranty soon.

  We want to virtualize these two servers (essentially the cluster), and then move all the data to the DELL EQUAlLOgic SAN we have on our site as well.

  Now, I've read that MS Clusters are supported in Update1 of VMware 3.5.

  So, how is it less setting this up. What I've read so this option seems like the next three - provide details of them my knowledge in VMware/SAN is very limited at present, but in the hope of picking up very soon.

  1 P2V cluster as it is

  2 break the cluster, then P2v each.

  3. create a new node 3 in VMware. (how we should go on the PV220s San data movement) - we should create a new volume-LUN of the SAN?

  I read that the signatures of discs cause problems etc..

  Please discuss your experiences and your thoughts on P2V ING a MS cluster.

  I'll be very be very thankful to you guys if you can answer because it will speed up our project.

  Hello

  Moved to the forum of the Virtual Machine and the guest operating system.

  Read http://www.vmware.com/pdf/vi3_35/esx_3/vi3_35_25_u1_mscs.pdf very very carefully before you P2V a cluster, there are things you need to do to create the virtual hardware correctly. If it were me, I would not use P2V but fresh start installs correctly configured virtual hardware.
