• Bandwidth of the network for the redo log switches

  Hi all

  I'm using Oracle 11 g R2, I want to clarify the necessary bandwidth of my primary site to the secondary site (using Oracle Data guard)

  My database is an Oracle RAC 2 nodes each node has a log size to 2 GB again. listen to this file in operation every 5 minutes. It means that I'm spending a 2 GB redo log file every 5 minutes from each node. This means that 4 GB in total every 5 minutes.

  I'm planing to set up Oracle Dataguard in maximum performance mode. Is that mean I need a link between the primary and secondary site that is able to transfer files of 2 GB + 2 GB every 5 minutes?

  I do the calculation below and need your advice:

  4 GB / (5x60s) = 13981 KByte/s

  This means that I need to link to 13981x8bites/s = 111, 848Kbit/s?

  Is the above correct? your advice please

  Kind regards

  If your users are complaining about slow at 15:00 then look at what is happening on the system at this point in time.  Use the Active Session history, providing that you have the license, at 3 pm to see if there is a problem.  Or take snapshots of the AWR manually around 15:00 in an attempt to capture any anomaly.  Or capture instant V$ SESSION yourself manually around 15:00 and see so many sessions is pending or not.

  I have seen problems like this on shared physical infrastructure systems where the activity on a system can interfere with each other.  Attention to this kind of thing, because if it is caused by another system then you will never find the cause of the problem inside the Oracle.  Examples include backups are made at a specific time, causing large amounts of sequential disk i/o and slows down access to the drive for everything else.  Such a scenario could cause some writing redo log time to increase significantly.  Or the backup could be another system completely who shares the same disks in the same drive bay or the SAN and Bay drives or SAN is inundated by applications e/s backup.  But as it's another system, that you will not see what is happening on your Oracle database system.

  Or a virtualized with environment sharing CPU and memory where another virtual machine running a CPU intensive job and steals the Oracle system CPU capacity.  I saw the same thing with memory so - Vmware has a strange way to virtualize memory, which means it can use all of the memory on the physical hardware and run out, and then he had to intervene to release somehow little memory.  What ends up slowing things down.

  It could be a network problem - is something that the network of the floods at 15:00?  Still, backups can be a common cause of this, during the transfer of data over the network to another system.  Is there a work extracted regularly data which runs at 15:00 for example extract given OLTP to feed into a data warehouse, which is copied on the network?

  It could be many different things, causing the slowdown.  I would definitely recommend watching any expected sessions know and see if this gets worse around 15:00, or if it remains the same, in which case the problem is elsewhere.  You must also eliminate everything else - the disks, network, etc.

  Good luck

• How to know the username of an account on a network share

  When I access a network share from another computer with windows Explorer, it tries to connect with identification information (current account & password or the credentials previously stored or depends on the settings of the remote computer as a guest), if not, it prompts for username & password (depending on certain parameters again). My problem is when I access a network share, I want to know my credentials (username) on the network computer.

  Is there any command or no way to definitely know what username I connect to a network share with windows Explorer?

  Original title: account in the network share

  Hi Aoikonomou,

  Thanks for posting your query in Microsoft Community.

  If I understand you correctly, you want to know the credentials of your system when you connect to a network share. I wish to inform you that all the names of login and passwords are supported by Credential Manager. By saving your credentials, Windows can automatically log in to websites or other computers. Credentials are stored in special files called vaults on your computer. Windows and programs (such as web browsers) can safely give the credentials in the vaults to other computers and websites.

  To know your Windows credentials, you can read the following steps to open the Manager of credentials:

  1. Press the Windows key + X.
  2. Click on Control Panel.
  3. Type "Credential"" " in the search bar and select credentials manager. "
  4. Click Windows credentials.
  5. You will be able to see the user names and password (hidden).

  In order to store passwords for automatic connection, see the following article:

  Store passwords, certificates, and other credentials for automatic logon

  Hope this information is useful. Let us know if you need more help, we will be happy to help you.

  -It is recommended that this switch Redo log 5 times maximum per hour, but I have this time of maximum peak about 100 redo log changes occur.

  -It is recommended to have the large size of the Redo log. But I have 3 Group of redo and each size is 50 MB by default.

  -My group of Redo log not multiplexed and it by default with each group have only a single Member

• ORA-16038, ORA-00354, ORA-00312 block header corrupt redo log

  Hi all
  
  I'm Ann. I'm not an Oracle DBA. Please bear with me. However, I have to accelerate to become a DBA during the time that the dedicated DBA is on maternity leave.
  As usual, we have the online site and test site.
  She gave me some notes about how to take care of the database of active and application (Oracle 10 g).
  But so far, I can't do a lot of command calls the site online because we have plenty of space for the server, also the biggest part of the task has been scripted. So, it can work automatically.
  
  However, the test database is not like that. There is not automatically restart scripts as in the live system.
  Recently I canont access to the test database. So I connect to the test server, find the folder that contains the Archive Log files is nearly 98%.
  So I remove some of the old dbf files (I did based on the Advisor to the Chief of this last time, it happened a long time ago)
  
  After clear some old files, make a df h the rate at 58%.
  However, the database is still not available (can't open I think)
  I connect to the database, making an immediate halt, but Hung Server.
  So, I ask a network engineer to restart the database server.
  Of course, the machine is stop so the database must be completed.
  After the machine restarts, I connect as sysdba but still cannot open the database.
  The error is as below

  ------------------------
  Normal users could not connect to the database. He messaged ORA-00257: internal connection only up to this just released. When you try to archive the redo log, it returns the message.

  Explanation of the problem:
  -------------------------------
  Whenever the normal user tried to connect to the database returns the error as it is designed in
  
  ORA-00257. But you've noticed that there is enough space in the V$ RECOVERY_FILE_DEST. Whenever you look at alerts log, you will see the ORA-16038, ORA-00354, error ORA-00312 serial. Produced error as because it doesn't have archives online redolog due to an alteration in the online redo file.
  
  Solution of the problem:
  --------------------------------
  Step 1) while making your database running clearly non archived redo log.
  SQL > alter the clear database untarred logfile "logilename";
  
  What makes corruption disappear which causes the contents of the redo online deleted file.
  Step 2) make a full backup of the database
  
  Is my question here safe to apply the following steps:
  We have 2 logs online that cause the error, until I need to erase the 2 files.
  
  For step 2, how to make a backup with RMAN.
  Can you suggest a command line safe for me to use. (The EM console surrently do not work on the test database server)
  
  I really need that test database managed as my apps APEX run on this need to be exported to the live system.
  
  Really appreciate any help here, once again, it's an Oracle 10 g release 1.
  
  Kind regards

  Your problem is with redolog 1

  SQL > select * v log$;

  check the status of the Group 1 regardless of whether ACTIVE or INACTIVE.

  If it is INACTIVE, then run the command below

  SQL > ALTER DATABASE CLEAR NO ARCHIVED LOGFILE GROUP 1;

  then

  SQL > alter database open

• Disk utility can not create large image of drive (60 GB) on the network share

  Disc Utiity (Versie 15.0 (1511.3)):

  I am creating a disc from a hard disk image. I want to save the image on a Synology DS414 network share.

  The share is accessible a there is no active disk quota.

  I copied a large file via Finder (384 MB) to the \\partagereseau that works.

  When I try to record a copy of disk sharing (60 GB), I get the following message:

  Unsatisfactory area is available on "(null)" to create the NAME of diskimage. Choose another volume with at least 60 GB of available space and continue.

  Summary: I can create large files on the share, but the disc utilities cannot?

  Greetings Wim

  384 MB is nowadays is no longer considered to be a file of "big."

  You don't mention how much space is actually available on the Synology but for arguments sake, we will assume that more than 60 GB of space is available.

  So in theory it should be possible to create a disk image of 60 GB (no doubt), there is enough space available. As you say there is no set of storage quotas and I'm happy to believe that. I think that the issue could be more to do with the maximum allowed size of the file, remember that I mentioned that 384 is actually not much, although some systems have a limit of 4 GB for a single file, for example FAT32 file systems have such a limit. In theory the FAT32 limit should not apply here because almost all including Synology NAS servers actually use Linux as the underlying software and so use Ext3 or Ext4 as file system, not FAT32. Same Ext2 a fortiori Ext3 or Ext4 allowing individuals will produce up to 2 TB of size which is clearly much larger than 60 GB.

  Still it could be related to that question even if it is necessary as an unnecessary and artificial limit may be for example to ensure compatible with other systems using FAT32.

  If you have enough space on the Mac, you could create and try to copy on the Synology, however another approach which is probably better all around is to create a "sparsebundle disk image. It's a disc image, but another type and will work around this problem because it is in fact made up of lots of all small files attached together. As that user do you see this as image a big drive, but the computer sees it as a folder full of files much smaller.

• Unable to save pennies on network share

  A user has problems recording on a share network as follows:

  His iMac runs El Capitan. She opens a PDF of his email and stores them on the desktop. She manipulates using Adobe Acrobat and recorded on network. However, it is now to find that when she tries to do a save as on the network share, the button 'save' is grayed out. I tested with Microsoft Word as well, and the same problem occurs. Recently it started to happen.

  If she copy and glue the documents from his office on the network share then there is no problem, and I told him to do this as a workaround for now. It seems to be no problem with its access to the drive that it maps without problem and she can open and manipulate documents from there. As a test, I tried this on her personal network drive and again the "Save" button is grayed out.

  I suspect there is a simple resolution to this, but I was unable to reproduce the problem on my Mac Mini running El Capitan - I can't save slot for readers network without problem. I searched the forums but cannot see a solution.

  Someone at - it ideas?

• Internet connection issues "Limited or no connectivity." and "windows could not find a certificate to log on the network.

  I'm so unable to connect to the internet?

  Hello.

  I'm so unable to connect to the internet.

  Since I've renamed our WiFi network and add a WEP key, I have problems with wireless connection on my
  Windows XP computer desktop, which is a Dell Dimension 4700.

  The questions that I get connection are...

  "windows could not find a certificate to log on the network.

  "Limited or no connectivity."

  I did all the solutions I could try to fix the connection problem!

  1. once I received the message "limited or no connectivity", I click with the right button on the connection and click on repair. It is not always connect for me and I got the "limited or no connectivity message.»

  2. then, I disabled the network connection and then enabled. That no longer works.

  3. I tried to withdraw from the ordered list of connections, and it still doesn't work.

  4. I checked the driver manager, and initially the Ethernet driver was outdated and missing of its pilot. He had a yellow question mark with a black sign and yellow with an exclamation mark inside.

  5. I used DriverZone, downloaded the driver, installed and rebooted the computer after the installation of the it. Apparently, it worked. But I could not always connect.

  6 I have ensured that I entered the correct WEP key, and then adjust the settings correctly. I did it like 10 times in a row and would not always connect.

  7. I tried to go to the command prompt and typed in IP Config/All and that's what I mean.

  Windows IP configuration
  Node type: unknown
  Active IP routing: no
  WINS proxy enabled: no
  ETHERNET connection to the Local network card
  State of the media: Media disconnected
  Description: Intel PRO/100 VE Network Connection
  Ethernet card 2 wireless network connection:
  Suffix the connection-specific DNS: (EMPTY)

  8. after that, I typed the command: ipconfig/release
  and then I got this error...

  No operations can be performed on the connection to the local network, although it has its media disconnected.

  9. after that, I tried Googling for some solutions, and the solutions I found were not any use.
  A solution was

  10. opening of Services...
  Start | Run | Type: services.msc | Click OK |
  Scroll down to and double-click Client DNS | Set to automatic on startup
  type |
  Click apply | Click the Start button | When it starts, click OK
  Do the same for the DHCP Client.
  Do the same for the remote procedure call (RPC).

  and it still doesn't work.

  11. when I look in the menu network connections, I see my connection with a lock on the side, with a red X under the lock and key. In the description, I see not connected, protected by a firewall. How could I remove the internet connection firewall? I disabled the firewall and that did not work.

  12. I tried to uninstall and reinstall the network card and who does not work either.

  It is not the network itself that is the problem.  It is not the modem or the cable. There are no disconnected son or something like that. We have other computers in the House and the internet works fine on other computers. As I said, since I renamed our WiFi network and added a WEP password, I had problems with connecting to my Windows XP computer.

  My computer has updates that must be installed as well. Updates would fix the problem? I just need to have internet.

  What should I do? Thank you for your time.

  Sincerely,

  Have you tried to set the value of the link speed/duplex mode? I had the same problem you describe. Your card is only capable of 10/100 communication.

• Accessing a network share is reasonable in response, but in sharing folders are slow to react. Can it be accelerated?

  When you browse a network share, \\LocalServer\Level1Share, with Explorer on an XP computer fully patched, the list of Level1Share has been quickly. If I try and open a file, say Level2Folder, I'll have to wait somewhere close to 2 minutes for a list. The share is on a Windows 2003 server, updated with patches, and the user has the appropriate permissions to the level of sharing and folder. Why and what can be done to fix this?
