• Network partitions

  I'm not clear on how the ONoSQL should behave in the case of a network partition.
  Assuming that a replica group is shared between two data centers that has ceased to communicate. The primary remains where it is (even if it's on a network partition and only a minority of replicas)? How is the 'other' network partition 'knows' it should not elect a new master replica?

  Alternatively, take at least one node crashed. As long as the total number of nodes that are high and communicators, forms a majority (assuming that the 'majority' usual default configuration), you're back in business.

• New addition ESXi host to vSAN, put in the new group of network Partition

  Add a new R730xd from Dell to my cluster active vSAN (also all the Dell R730xds, same features), but when doing so, the new host is put into another group of network Partition.  Same configuration of the switch, the new host is plugged as that of others.  Can check the connectivity between each host (in addition, confirmed as much as I can ping to the interface vSAN between one of the four hosts), yet always says there is a communication error.  Any ideas?

  Certainly a multicast problem, strongly recommend the reading of these:

• Virtual and Exchange2007 Cluster networks

  Hello

  I'm currently in the planning phase of virtualization and the upgrade of our Exchange 2003 to exchange 2007 and the 2007 on esxi 3.5 version

  I have 2 IBM x 3650 each server is connected to a SCSI Bay for storage.

  The current (already in production) server has 2 network cards, the 2nd (new) Server 6 network adapters.

  For the cluster (2008) GUEST OS, I need to assign 1 to talk on a private IP connection network card and 1 card network to talk to the local network. If the two guests were going to be on the same HOST, then I think it would be easier, but for redundancy they need to divide. I know what I have to do, which is assigned 1 network card PHYSICAL to a virtual network adapter on each server, which will be easier on the new server with more than 2 network cards, but on the NIC 2 would be the server, network adapters are associated, so I still would be able to send the private link to down one of them?

  The servers are connected to a stack of Cisco, and I got 2 configured ports in a VLAN private for private sign, with a port as a trunk so that he can speak both the LAN and the private VLAN.

  I just need a little help in the implementation of the virtual network adapter to the network card physical environment and apply on the HOST servers.

  I just need a little help in the implementation of the virtual network adapter to the network card physical environment and apply on the HOST servers.

  Create a Virtual Switch.  Assign a NIC (that is not in use).  Then, assign him VM to the virtual switch.  That's close enough, you can do from the VI Client software, command line not involved, it's all the gui.

• When installing a new operating system isn't automatically wipe the hard disk, create a new partition, and then install the operating system?

  Have a Dell system, caught a virus and it has really messed up the PC. Recently, it got worse so I tried to reinstall the operating system with the Dell disks. It wouldn't work. So I bought for Windows 7 Professional, it will not be installed. My first question when installing a new operating system isn't automatically wipe the hard disk, create a new partition, and then install the operating system? Because this does the same as the Dell disks, is to take what is on the hard drive and put it in a folder called windows old, is not formatting the HD. When I boot the disk, it shows the installation of files then open windows and start the installation. Before he could finish I get an error missing or corrupted files. Tried several times now, windows will still not open. Any suggestions? Once while trying to install the pc crashed with a blue screen which is one of the reasons why I have reinstall the OS, he started to plant a few times. I don't remember all the details on my PC, but its 4 years, triple core coprocessors, ram 8 GB, 500 GB HD. At the same time just after all this started in Jan. I had also improved my 3 GB to 8 GB memory. I bought the Dell memory for my system. Since the crash, could there be a problem with these new memory chips? Last night I tried to disassemble each and reinstalling it, but that doesn't seem to make a difference. Before I tried to reinstall the operating system, the pc was see the concert 8.

• Size of the partition and Index Local

  Hi all

  Database information: 11.2.0.3 64-bit Linux. It is a 3 RAC Cluster node.

  I recently partitioned a Parent and child tables as PARTITION of REFERENCE set. The parent table has been RANGE - partitioned. The first partition is on an integer column and the beaches are 0-1000, 10001-2000, 20001-30000 and so on. The secondary partition is on a date and it is partitioned for each quarter.

  I created a local index as follows (faullt2vehicle, offboard_load_date, record_type, Column_Y).

  Here's an example query I will carry out, where the date is covering 2 secondary partitions

  select  * from gets_tool_Fault t where fault2vehicle                                      = 12195
  and offboard_load_date                                 BETWEEN TO_DATE('2015-04-01 00:00:00', 'yyyy-mm-dd hh24:mi:ss')
  AND TO_DATE('2015-07-01 00:00:00', 'yyyy-mm-dd hh24:mi:ss')
  AND record_type                                        IN('FLT','STP','HC','EGU','EOAEQP','CEL')
  

  When I generate the plan explain below is the output

  If you observe the optimizer is currently to identify the partition, and then the secondary partition, but what is confusing to me, this is why the restricted PREMISES index scan scans all secondary partitions for a given partition. The partition should be not even as a value from PARTITION RANGE ITERATOR of 7 and 8.

  Interestingly, when I provide a date range which is in single partition the pruning is happening correctly

  1. your index (faullt2vehicle, offboard_load_date, record_type, Column_Y), your query has a predicate based on a beach on the second column in this index, which means that the order of the index that must be examined is dictated by this predicate and each row in the range must be considered (filtered) to check the third predicate.  Basic guideline on the column in the index you are ordering for more effective use: If you have columns where predicates are always equal put these columns at the beginning of the index, the columns where predicates are usually based on a beach go towards the end. You seem to have been misled by reviews 'the prefix local index' stick to your two columns of partitioning at the front of your index - which should NOT be an automatic choice for the local index: see this note ( https://jonathanlewis.wordpress.com/2011/02/28/prefixed/ ) comments that follow and OTN article it is linked to.

  2 since you have two indexes that start the same way (this goes with the local prefix again) you made easy for the optimizer to choose the index (for you) is clearly evil. That's why behind the choice of the optimizer is probably another example of an issue that I spoke a few days ago: Re: Composite index + map selection N1 your index is probably greater than the index of C7, and the order of the entries in the C7 index probably makes the data much more dispersed that it really is (i.e. high clustering_factor).

  Concerning

  Jonathan Lewis

  PS (update):

  If there are many rows for each fault_id, then you must create an index from fault_id with 'compress 1' (or compress N if the first columns of the index N are repetitive).

  When dealing with range partitions do not forget that the high value partition is never reached in the document, do so based in the form "date_col BETWEEN date1 and date2", use the form "date_col > = dateX and date_col»< datey"="" or="" you="" may="" find="" that="" you="" are="" accessing="" one="" more="" partition="" than="" you="" hope="" to,="" and="" in="" some="" cases="" that="" may="" mean="" "multiple"="" (i.e.="" 2)="" when="" you="" were="" expecting="" 1="" (and="" the="" optimizer="" is="" much="" better="" at="" estimating="" costs="" for="" a="" single="">

• The network infrastructure for a stand-alone server or a Cluster Network Infrastructure?

  Hello

  I want to install a single instance database and I want to use ASM.

  My setup is now just one node but in the future probably it evolve on several nodes.

  So, can I use the Network Infrastructure for a Cluster to a single node, or I have to use a stand-alone server network infrastructure?

  Concerning

  If you later plan ro use more than one server to install the cluster network infrastructure. It is possible to install on a server.

• List of all VM network name and IP address

  I am trying to get my head around powerCLI.

  I want to create a script that will the virtual machines on a cluster of output and display their network name and IP address.

  I have this so far.

  (get - vm). %{
  $vm = $_
  echo $vm.name.
  $vm. Guest.Nics | %{
  $vminfo = $_
  echo $vminfo.NetworkName $vminfo. IP $vminfo. MacAddress
  echo '; ' n ';
  }
  } | Export-Csv C:\vm_nic_report.csv

  I'd love to be able to limit the output on the cluster baised, but I can't understand this.

  If I run it without the Export-CSV, I see the info that I need on the screen, but if I add the Export.csv, my CSV is a colum with a bunch of numbers and no real value.

  Hello, TdisalvoOrinoco-

  If you want to limit the output to virtual machines that reside in a specific cluster, you can just start the whole expression with a Get-Cluster and then direct to the Get - VM with which you start currently (or use the - rental on Get - VM parameter).  Thus, the first line would be one of:

  &{Get-VM -Location (Get-Cluster myCluster0) | %{    $thisVm = $_    ## a hashtable for holding properties to be returned    $hshNicInfo = @{}; $hshNicInfo["VMName"] = $thisVm.Name    ## for each NIC, build some info with MACAddr, IPInfo, and Network Name    $thisVm.Guest.Nics | % -Begin {$i = 0} -Process {        $oThisNicInfo = $_    ## the current NicInfo item        ## get the IP info (IPv4 and IPv6 if there, which should be available if VMware Tools are running)        $strIPInfo = ($oThisNicInfo.IpAddress | sort) -join "/"        ## add the NicInfo items to the hashtable for later use with New-Object        $hshNicInfo["Nic${i}MACAddr"] = $oThisNicInfo.MacAddress        $hshNicInfo["Nic${i}IPInfo"] = $strIPInfo        ## this does not seem to have the network name if the portgroup is on a distributed vSwitch, so changed to the line after it        #$hshNicInfo["Nic${i}NetName"] = $oThisNicInfo.NetworkName        $hshNicInfo["Nic${i}NetName"] = ($thisVm.NetworkAdapters | ?{$_.MacAddress -eq $oThisNicInfo.MacAddress}).NetworkName        $i++    } ## end foreach-object
  
      ## once the hashtable is populated for all NICs, create a new object with the info    New-Object -TypeName PSObject -Property $hshNicInfo} ## end foreach-object## sorting goodness from LucD (of course) at http://communities.vmware.com/message/1769991#1769991} | sort -Property {(Get-Member -InputObject $_ -Name "Nic*").Count} -Descending | Select VMName,Nic* | `    Export-Csv -NoTypeInformation -UseCulture C:\temp\vm_nic_report.csv
  

  This is similar to the script posted in the thread http://communities.vmware.com/message/1848022#1848022 (which post has a bit more info on the necessary sorting for good performance, but also another way to recover data, using Get - views).

  In any case, it is a little more that you might write to debut with PowerCLI, but that he gets the output you're looking?

• Need to take stats twice for partitions and subpartitions?

  Hello world
  
  I'm taking a new approach for making statistics.
  
  First my system:
  
  Oracle 10.2.0.1
  3 instance RAC running on Linux RH AS 3, 64-bit
  
  I'm currently my stats using dbms_stats.gather_schema_stats with the option "rally car", it's good because only the data tables with stale and empty tables are being analyzed, but the process takes 3 to 4 days...
  
  Now I want to spread the statistical processes on nodes in the cluster using gather_table_stats (stale tables and empty tables only), while I was doing my procedure, I discovered the following, and here's where I need your help.
  
  If I run the following command:
  
  exec dbms_stats.gather_table_stats (ownname = > 'CACOSTA', tabname = > 'subpart_date', granularity = > 'SUBPARTITION', partname = > 'P200901')
  
  I can see the stats from my server BUT no stats have been taken for the partition.
  
  If I change the granularity on the "PARTITION": gather_table_stats
  
  exec dbms_stats.gather_table_stats (ownname = > 'CACOSTA', tabname = > 'subpart_date', granularity = > 'PARTITION', partname = > 'P200901')
  
  It will take the stats ONLY for the partition, but not for subparts.
  
  If I take the stats twice for 'PARTITION' and 'SUBPARTITION', I'll get all stats but it will take twice as long to complete.
  
  Is someone can you please tell me if I'm on the wrong approach? is it possible to understand that when I use the granularity of the "PARTITION", it can take the opportunity to use this same information it is collecting and provide statistics for subparts too to the RDBMS?
  
  Thank you and sorry for the long post.

  Carlos,

  This composite partitioning (range-list, range-hash) do you use?

  First of all I think it's important to understand that statistical subpartition will actually not to be used by the cost based optimizer in previous versions 10.2.0.4 (but in 10.2.0.4 only with bugs without patch installed, see the link to the message below) and 11.1.0.6:

  http://Oracle-Randolf.blogspot.com/2007/03/subpartitions-and-optimizer-statistics.html

  http://Oracle-Randolf.blogspot.com/2008/04/revisiting-subpartition-pruning-and.html

  http://Oracle-Randolf.blogspot.com/2009/03/partition-oddities-part-1-severe-bug-in.html

  So, I'd be interested to see a case in the database pre - 10.2.0.4 where the optimizer actually using subpartition level statistics; I have not yet found one.

  Second, he must be aware of what Oracle offers several ways how to maintain the different level of statistics:

  -Less consumption of resources, but less quality: collection of statistics on the lowest level (e.g. subpartition) only. I hope all subparts of the partition have statistics, the higher levels (partition / global) will be inspired by the aggregation. This way, you get the low quality statistics on levels higher (e.g. no histograms will be generated by aggregation, number of distinct values potentially quite inaccurate), but you do not need to collect statistics on these levels. Note that if once you have collected statistics on the higher levels (indicated by the "GLOBAL_STATS = YES" column in the DBA_\ * views STATISTICS) will not perform this statistical aggregation. You must first remove the statistics of higher level using DELETE\ * _STATS have enabled new aggregation (next time gather you statistics on low levels and all partitions (sub-) have statistics)

  For more information about this approach, see for example here: http://oracle-randolf.blogspot.com/2008/04/exchange-partition-and-aggregated.html

  -Consumption of resources, but of better quality most: separate statistics on all levels

  - And the new modes supported by 10.2.0.4 and especially 11.1.0.6: APPROX_GLOBAL AND PARTITION (10.2.0.4), true incremental global statistics in 11.1.0.6 and the new algorithm for estimating AUTO_SAMPLE_SIZE introduced in 11g:

  http://structureddata.org/2008/07/16/Oracle-11g-incremental-global-statistics-on-partitioned-tables/

  http://structureddata.org/2007/09/17/Oracle-11g-enhancements-to-DBMS_STATS/

  http://optimizermagic.blogspot.com/2009/02/maintaining-statistics-on-large.html

  Another very good synthesis about the management of statistics has recently been published by Karen Morton: http://karenmorton.blogspot.com/2009/02/new-paper-and-cj-date-advert.html

  So in your case a database pre - 10.2.0.4 you should not bother with subpartition statistics at all (or you can show me otherwise I would be interested), and you can then try to find out if you could live with the above statistical approach of "sum" by simply collecting statistics on the level of partition, or if you need to collect statistics on the partition and the global level separately (you did not mention your current strategy to the global level statistics).

  If you install the 10.2.0.4 patch game you have several options and statistics subpartition can be used by the optimizer (but only in the case of beach-list composite partitioning, as far as I know), for example by using the option of PARTITION AND APPROX_GLOBAL introduced in this version. Note that you must install the unique patches to get this working properly as described by my post and the optimizer of blog post for the development group.

  Kind regards

• Shrinking Bootcamp partition and add space for Macintosh HD

  Guys, after helping me with my previous question, my Macbook is almost as I want it to be. As said, I have a Macbook Pro 15 "retina end 2013 with OS X El Captain (later) and in addition, a Bootcamp with Windows partition 8.1." It's that everything works fine now, but the partition Windows 8.1 has 300 GB and my score only 80 GB hard drive Macintosh.

  I wanted to shrink the partition, Bootcamp in Windows 8, 1 with Minitool Partition software but, obviously, when I reduce this score I get unallocated space that I can't turn into a new partition because I have 4 partitions in the MBR slot. So, what is the best way to reduce my Bootcamp partition and add space on the Macintosh HD partition?

  Thank you very much!

  Remove the Boot Camp partition, and Windows using Boot Camp Assistant. Then start to affect the size of the Boot Camp partition you want.

• Bootcamp (Win10) has not started after you changed the partition and updated at El Cap.

  I have a MacBook Pro (retina, 15 inches, end of 2013), 2 GHz Intel Core i7 with 8 GB of Ram.

  I had 2 system installed, Win 10 + Yosemite from the windows of beginning and the use of most of the time.

  Yesterday, I ran out of disk space and passed the partition in OS X with disk utility.

  While I changed the partition and I also upgraded to the El Cap.

  After all, I can't start by winning 10 more, although I could see my windows in the startup disk Control Panel.

  I checked some thread here and mess with command autour terminal, but nothing has worked for me.

• I create the partition, bootcamp and error when the window installation, after that back to el capitan os, but it can not find the bootcamp partition and can't erase the master disk to re install mac os

• System partitions and upgrade to Windows 7, Linux

  Yesterday, I bought my first CV - ProBook 4515 s model with SLED 11 Linux preinstaled. Given that I'm not familiar with Linux systems first thing I did was to install Windows 7.

  My laptop came with 4 partitions that is formatted in a file system that Windows does not recognize. I'm guessing a partition for installing Linux, two of them are system (HP_TOOLS and HP_RECOVERY) partitions and the fourth was just an empty disk. So I formatted the fourth partition and installed Windows 7.

  The problem is now that I am out of system partitions, so can not access other software preinstaled and QuickLook. I tried a single partition format and rename it to HP_TOOLS and then tried to install QuickLook v. 3 but the facility reported that my system has not been supported? I don't want to mess with the other partitions in the fear that I could remove the BIOS, but want to sort this mess up and would certainly like to have some of the options that is is installed with the system.

  Any suggestions?

  Message edited by Martine on 14/10/2009 14:07

  I think that the HP_TOOLS and HP_RECOVERY partitions are formatted as ext2 or ext3 file system, Windows cannot read. It can only read NTFS and FAT32. There is no way I can think to convert the ext2\3 to NTFS without keeping the integrity of the system. In addition, the files are all intended for linux and not Windows. He has makes no sense to do that. That said, I'm not sure if your laptop has Windows 7 drivers now.

• ProBook 650: Drive Partitions and Windows 10 upgrade

  Hello

  I'm here to find some information on Windows 10 because I want to upgrade my system, now it's Windows 7 Pro (64 bit). I downloaded the Windows ISO 10N Pro yet and before doing the upgrade, I'll create a complete backup of my drive using Macrium Reflect.

  I have now four partitions:

  1. Active NTFS, 500 MB system
  2. (: C) primary NTFS
  3. (: D) HP Recovery - NTFS primary
  4. (:) E HP Tools - primary NTFS

  In which partition Windows 10 installs?

  I have to choose, or it's an automatic installation?

  I should delete some of the partitions?

  W10 upgrade will remove one or more partitions?

  Thank you very much for your help!

  PS: how to check if the driver are compatible with W10?

  I upgraded to win10 of many PC Win7 - and everyone had some issues that needed to be overcome.

  Your plan to make an image with MR backup is the best approach, because, although Microsoft says that there is no risk in the upgrade of Win10, because they allow you to believe that you can always go back to your original OS and setup within 30 days, the ugly fact of the matter is that the Win10 GoBack feature turned out to be unreliable - and when it fails She can let the machines in a corrupt State - which is not always the case, it happens often enough to be a problem, but you will get no warning beforehand that he goes to the trash your PC!

  With regard to your questions:

  (1) installation partition: you already have 4 partitions at a higher level, so unless your drive is formatted in GPT (which is probably isn't), you WON'T get a meaningful choice about where to install Win10, because only the C: partition will be enough space.

  (2) deletion of partitions: while you can migrate HP tools stuff it into the C: partition and then delete HP_TOOLS, which really won't help much because this space is much too small to be useful.

  (3) with the recovery partition.  Don't count on that it works. The Win10 upgrade is known, in some cases, corrupt the partition of recovery that are stored by the OEM that built the original machine.  It's pretty much guarantee that no HP recovery will work. Thus, based on the recovery of Win7 partition back to Win7 is a mistake.

  Your backup of Mr. is safest and most reliable way to have a backup plan to return to Win7.  You do not mount the image to a restoration, instead, you start from media that you have created using MR, connect the external hard drive and then use the restore option to select the backup that you did.  So, be sure to exercise the option MR to create bootable media, you will need later to do a restore.

  Good luck
