• How to use an expression with "Derived physical mapping.

  I'm trying to use an expression in the "Physical mapping Derived" option in the business model. I chose the 'University Code' logical column and then I clicked on "Edit" option under the "Derived physical mapping. I tried to put the phrase in two different places - in the "Column mapping" tab and in the tab "Content", under "Use this WHERE clause to limit the rows returned"-, but neither one worked. The system gives me an error, but also, there is no search.

  Is there something wrong with the expression below, or I am connect the expression in the wrong place?

  CASE

  WHEN "orcl". » ». "" "" EDCS_CORE '. "" D UNIVERSITY '. " UNIVERSITY_CODE"= 'DOMC' THEN 'CARL '.

  WHEN "orcl". » ». "" "" EDCS_CORE '. "" D UNIVERSITY '. " UNIVERSITY_CODE' = 'NOMS-LAKE' THEN 'NOSM.

  WHEN "orcl". » ». "" "" EDCS_CORE '. "" D UNIVERSITY '. " UNIVERSITY_CODE"="NOMS-LAUR"THEN"NOSM.

  WHEN "orcl". » ». "" "" EDCS_CORE '. "" D UNIVERSITY '. " UNIVERSITY_CODE"="LAUR-ALGM"THEN"ALGM ".

  WHEN "orcl". » ». "" "" EDCS_CORE '. "" D UNIVERSITY '. " UNIVERSITY_CODE"= 'LAUR-HRST' THEN 'HRST.

  ANOTHER "orcl". » ». "" "" EDCS_CORE '. "" D UNIVERSITY '. " UNIVERSITY_CODE ".

  END

  Hello

  So let's not forget the 'Content' tab and the WHERE clause field (this is something else and you don't need here).

  If you open the logical column properties, go to the tab 'Source column', you are supposed to have the "physical mappings Derived' already activated (because your column come from the DB).

  There you click on the LTS source and click 'change '.

  You have now before you all the columns from the source to the logical Table mapping.

  Select your 'Code of the University' column, and then click the "fx" (top right of the window).

  Here, you can put your CASE WHEN.

  If you are not satisfied with the result (no given or not look it up), have a look at the generated SQL physical (your BOX WHEN is inside) and where is the problem (maybe your column in the DB has spaces before or after the codes and things like that).

• physical mapping of MDB TIMESTAMPDIFF or derived expression

  Is it all the same to install a timestampdiff calculations as a derived column aggregation and get or must it be done as a physical mapping?

  TimeStampDiff (SQL_TSI_DAY, "xxx". "Fact". "" From the Date", VALUEOF (NQ_SESSION. ("' EFF_TO_DATE") if I try this using "Of Date of application" the fact or dimension, the calculation shows up with tab grouping darkened.

  Derived columns are supposed to apply the post aggregation calculations - so the tab is grayed out.

  Your best bet is to use TimeStampDiff in physical mapping.

• Several physical NIC cards connected to vSwitch / Port Group

  Hello

  I have several physical NETWORK adapter on a host connected to a single vSwitch / port group, does this mean that the speed of the network is shared by all of the physical NIC, or I have to do something special to enable this feature?

  Please see attached .jpg

  Thanks in advance.

  If all of your network adapters is active in the nic teaming configuration, you must have a physical switch that supports the aggregation of links and you must configure it. The ESX itself does not have this kind of work.

  Actually is a bad idea to let all NICs connected without having to configure the nic teaming (1 active and others waiting for failover) or without going through the aggregation of links.

  Hello

  What is the maximum physical NETWORK card, I can connect to vswitch?

  I would say the number is equal to the number of physical NIC in ESX host max...

• In stand by mode physical map?

  Hello

  I am running vSphere Server version 5.1.0 (build 799731).

  All my ESXi hosts have version 5.1.0 799733.

  I noticed that on some on my ESXi hosts, one of the physical card for the vMotion VMkernel oucederomsurlesecondport IDE, is in stand by mode, but the other physical card is in normal mode.

  I have attached a screendump of the question.

  Can you help me explain this?

  Kind regards

  Assuming that the two uplinks are configured properly, the usual configuration would be to have two active uplinks to the vSwitch and override settings in the groups of ports. For example vmnic0 active/vmnic1 stand-by for the management and vmnic1/vmnic0 active waiting for vMotion. In this way both management vMotion having their affair rising dedicted unless there is a failure of the link.

• Cards (NICs) Ethernet in the RAC configuration

  DB version: 11g
  
  
  I came across this nice link on the RAC configuration
  http://www.akadia.com/services/ora_rac.html
  
  Question 1.
  
  Cons. in the diagram, I can see eth0 and eth1 in both nodes. They are physical maps ethernet (NIC). Right?
  
  
  Question 2.
  Each node has 2 ethernet cards is common in the industry. Right?
  
  
  
  Question 3.

  For Private InterConnect ===>One ethernet card from each node, connected via Switch1
  
  For Public InterConnect plus Connection to Shared storage  ====> One ethernet card from each node, connected via Switch2

  This is the standard practice in Production DBs?

  A question that you asked and there are very important with regard to the questions you have asked - what is the best technology to use for interconnection (private network and switch)?

  And is not ethernet (as shown in this diagram you mentioned). The speed and scalability of the interconnection have a major impact on the performance of the cluster.

  Gig-ethernet is limited in scalability and features. 10 Gb/s is the maximum. The standard of 1 Gbps. It does not support SDP (Sockets Direct Protocol), SRP (SCSI RDMA/Remote direct memory access Protocol) and so on. (although SRP specifications were available to sellers for implementing ethernet).

  If you look at what Oracle Database Machine and Exadata storage servers is using, this is Infiniband... and protocols such as SRP.

  InfiniBand out-of-the-box works at 40 Gbit/s (extendable up to 120 GB/s). Port to port latency is as low as 60ns (and still less with hardware and new technologies of the IB).

  I don't see how GigE even thinking to challenge Infiniband with in this regard. Especially since Oracle himself chose as the interconnection architecture (and layer of communication of storage) for the fastest CARS ever built systems.

  And no, it's not expensive either. Our IB material cost us really less similar material GigE.

• Error UCSM Serive Profill [not enough vNIC, connection-investment, not enough global resources]

  Hi guys,.

  I work in Cisco, and we have a problem for a few days, so I thought it would be useful to ask here.

  We created the service with 3 vNIC profile and tried to associate it with a server [actually, we tried 4 different servers] and always, the error we get is:

  "not enough vNIC.

  connection-investment

  There's not enough global resources. "

  Once I realized the error code is F0327, but not always.

  I suspect it's something with the IO Module or do not know what?

  Please, can anyone help?

  Thanks in advance,

  Ron

  Hi guys,.

  I just wanted to post this for everyone else reference.

  Blade: B200 M1

  Adapter: Cisco UCS M71KR.-e.

  3 VNIC was applied. Two NICs FOR interconnection fabric A and b. interconnection 1 VNIC to the tissue that was a fail with the error "connection placement. This is due to the fact that this card is part of the series of Menlo, in which physical network adapters are mapped to left and right that they can't stand to not "allow failover. This is due to the hard Menlo being mapped to each fabric interconnect so that would mean a VNIC / VHBA by the interconnection fabric.

  Once this has been corrected this error disappeared and the association of service profile is complete.

  Kind regards

• Newbe question on dual nic host

  I have a HP DL360 G5 with two network adapters.

  What I am looking for is Internet access to all my virtual machines.

  I do a test lab that I don't want to not talk with my corp network.

  I installed esxi 5.1.0X

  vSwitch0 has VM Network on it and networking with vmnic0 as physical map

  vmnic0 is map of networking with IP 10.10.180.5 subnet 255.255.255.0 no gateway

  I have a server control and exchange of the field for test purposes.

  the NIC physical is connect to a port 8 switch so I can plug in laptops to and they shoot great domain controller IP so it's all good.

  I need Internet access to make updates on the servers, I bring some access.

  Now I have a spare internet connection which distributes IP addresses like 96.185.50.X

  I plug which vmnic1 free access to the Internet, but no IP address is assigned.

  He created a VM Network 2 Vswitch1 and vmnic2 is the physical map
  How to assign an IP address the second NETWORK card and how to route Internet traffic between the vSwitches so that VM on the other network of VM can get internet Access

  Is it still possible?

  Thank you

  You could add a 2nd vNIC to each of your virtual machines and attach it to Network 2 VM but this means that each of your virtual machines will need a 96.185.50.X its IP address, you also need a default gateway and DNS on this interface, I guess that it is set with DHCP.

  Or you can create a virtual computer to be used as a router between 1 network of VM and VM Network 2. This virtual machine will have two vNIC, one on VM 1 network and the other on VM Network 2. Give VM 1 network interface a static IP address on your network of 10.10.180.0/24 and use it as default gateway on your other virtual machines so that they use it to get out of the internet. You need to configure DNS on your virtual machines so that they can resolve internet host names.

• Try using four nic as an external switch ports

  Hello

  I have a quad port gigabit nic in my esx Server I want to use it as a 'switch '.  that is, I have a vSwitch with all my VM on it, and I have included 5 NICs in there.  One is an internal NETWORK interface that works very well, and the other 4 are quad port PCI-E adapter.  For some reason when I plug a physical computer into one of these 4 ports, I'm not able to get a network connection and cannot communicate with the virtual machine.

  Is there something I'm missing here?

  Thank you

  Hi Dontinou,

  If you want to connect physical machines directly to external ports? It is not how ESX should work but why not, special purpose...

  First of all, you need to use crossover cables (or have the network card can detect direct connections).

  Then, you must have a group of port by physical map (or a vSwitch) because when you join a virtual computer in a vSwitch, it uses all the physical ports but only one. Then configure each port group to use an identified uplink and attach each virtual NETWORK adapter to a group of different ports. Finally, give a different IP address to each vNic.

  The problem with this design is that you need to configure each physical machine the IP addresses of the virtual machine they want to contact on they are connected to a specified card... It's not easy. And physical machines will not be able to contact each other, unless you install a router within the ESX VM.

  You'd better buy a small switch.

  Good luck.

• Editing assignments of NIC on Vswitches

  If I move s nic on the esx host to one virtual switch to another to increase the flow on another virtual network for example to move a network adapter of my switch from service console to my vswitch primary production for a total of 3 is the need for network services must be restarted to take advantage of this additional card to improve the flow?

  Thank you

  Ahh.  In this case, your secondary NETWORK adapter should not be used.  By default, without a port channel, your vm vNIC (in this case, your service console), can use only actively a teddy bear at a time.  This risk is mitigated in the VM networks by creating several virtual machines, considering that each virtual machine will use a separate bear that that of the previous vm used.  By default, since you have a service console vNIC/IP, you will use only 1 physical map.  What you can do is to create a 2nd vswif (vNIC/service console IP) and give the service console to another way out.  If this 2nd interface is on the same VLAN or segment, then you will need to create static routes for the backup traffic go on the 2nd interface and, by extension, the 2nd physical map.  Alternatively, you can change the settings of portgroup for your service console and use 1 Teddy as active, so the 2nd as the day before, and for the 2nd service console interface, have it serve as active 2nd and 1st Eve.  Forcing what you would expect ESX to do on its own.

  But, simply by adding the 2nd Teddy, will not accomplish your objectives in this scenario.

• Which physical network my virtual machine port is connected to?

  Hi all

  We have several ESXs with classic vSwitches or dVswitches. All of them have several physical ports (classic NIC teaming configurations, all cards are active).  Different virtual machines are connected to these switches (a vnic by VM).

  Is there a way to identify which physical port every single VM is connected to? Of course, I have no access the physical switches...

  Thanks for your advice.

  You can this output to esxtop commands (press 'n') in vSphere 4. Thank you
