• Need help to understand the network of vSphere environment

  Hello

  I need your help in understanding the network environment in vSphere. Please see the diagram and the text below:

  

  NIC #1 - Management Port (access from client vsphere, vCenter server)

  NIC #2 - Port of VMkernal (for iSCSI, vMotion, etc.)

  NIC #3 -?

  #4 – CARTE NETWORK INTERFACE?

  Q1 how allow external users to access services over the ESX host? (for example, IIS, FTP, Exchange, NFS)

  Q2, what will be the role of the other two network cards? Is it connected to the physical switch?

  * Ask you all to please help me by sharing your knowledge / experience on the network portion, you have made in your environment as NIC how, what to do with that. *

  I really need to understand the networking of concepts in vSphere, hope that your help!

  
  

  Best regards: Yash

  With an additional NIC with 2 port a general configuration might look like this:

  vSwitch0 - vmnic0, vmnic1 (connected to different physical switches)

  Network VMkernel management

  VMotion VMkernel network (own IP network, own VLAN)

  Better if they is configured as active / standby.

  vSwitch1 - vmnic2, vmnic3 (connected to different physical switches)

  Trade VM

  vSwitch2 - vmnic4, vmnic5 (connected to different physical switches)

  VMkernel iSCSI (own IP network, own VLAN)

  Ideal if it is added to the component Multipath iSCSI, which is quite easy to vSphere 5.

• Need help to understand the query result

  Hi gurus

  I was reading one of the question here in this forum and its link is below:

  Query required for scenario

  I had some confusion related to this code and don't understand the logic of the out put, see query below:

  Query

  with sub_services as

  (

  Select su_seq 12323, 'HLR1' so_id, 1 seq Union double all the

  Select su_seq 12323, "HLR2' so_id, seq 2 Union double all the

  Select su_seq 12323, "A09" so_id, seq 3 of all the double union

  Select su_seq 12333, "MO1" so_id, seq 4 Union double all the

  Select su_seq 12333, "MO2' so_id, seq 5 Union double all the

  Select su_seq 12333, "A09" so_id, 6 seq in union double all the

  Select su_seq 12333, 'M0CR' so_id, seq 7 Union double all the

  Select su_seq 12999, "LOL1' so_id, seq 8 Union double all the

  Select su_seq 12999, "LOL2' so_id, seq 9 double

  )

  Select *.

  of sub_services b

  where exists (select 1 from sub_services

  where su_seq = b.su_seq

  and so_id = 'A09.

  )

  order by 2;

  The query result

  12323 A09 3

  12333 6 A09

  12323 HLR1 1

  12323 HLR2 2

  12333 M0CR 7

  12333 4 MO1

  12333 5 MO2

  According to my understanding, the above query should return records in red only because of her is below command

  It exists (select 1 from sub_services

  where su_seq = b.su_seq

  and so_id = 'A09.

  but don't know why he's back 7 files, can someone help me understand the result...

  It is query is functionally identical to the PL/SQL block, but much more effective.

  declare

  number of l_res;

  Start

  for line (select *)

  sub_services) loop

  Start

  Select 1 from l_res

  of sub_services

  where su_seq = row.su_seq and

  so_id = "A09" and

  rownum = 1;

  exception when

  NO_DATA_FOUND then

  null;

  end;

  end loop;

  end;

  Essentially every row in the outer query are tested against him exists query.  Given the correlation between two requests is based only on su_seq each line with a su_seq value returned by him is returned in the output.

  Another way to think he uses instead a join condition.  This query is equivalent to the query to exist

  Select the main

  of main sub_services

  Join select (separate su_seq

  of sub_services

  where so_id = "A09") cond

  We main.su_seq = cond.su_seq;

• Need help to understand the collection

  Hi all

  I'm trying to understand the concept of collection, but when I look in the documentation that exists in google.ca, then, it seems very confusing. If someone suggest me or send me some simple examples and good collection and I really appreciate it. Thanks in advance.

  Concerning

  Line

  Thanks for the explanation, could you please explain what does really to take care of the index as a whole and clause varchar2 and if yes then what condition we use varchar2 index and in which condition we use index as a whole, be we just use index by integer in our daily practice. Really appreciate your response. Thank you

  Generally if you use collections, especially PL/SQL-only collections, your architecture is probably wrong. Collections are rarely necessary, but are often USED in the mistaken belief that they will help performance.

  The use of the collections usually DEGRADES performance, sometimes severely, and they are often used in a way that is not scalable. You should avoid using collections if possible.

  So don't use the collections AT ALL in your 'common practice '.

  For the rare cases where there is to use an array associative index type to use depends on the data type of the element that you will use for the index. If you plan to use a string, then you use INDEX OF VARCHAR2. If you plan to use an integer, then you use INDEX BY PLS_INTEGER.

  What type of index to use has NOTHING to do with performance.

  One of the WORST mistakes developers make is to use an associative array as target of a BULK COLLECT INTO instead of using a TABLE IMBRIQUEE. Collection in bulk is more often used in a FORALL statement so that the elements are accessible only in the order. Useds "indexed" access with associative arrays isn't even necessary or used.

• Need to understand the features of LEVEL when printing from 1 to 100

  Can someone please explain to me how the following query?

  SELECT LEVEL just_a_column

  OF the double

  CONNECT BY LEVEL < = 365

  I tried to understand Oracle generator line Techniques - Oracle FAQ , but I did not understand much.

  Hello

  ORA - aff wrote:

  Thanks Frank. I appreciate your response.

  Can you please explain more about how "CONNECT LEVEL <=> works in this query?"

  I understand when it is "CONNECT BY PRIOR emp_id = mgr_id" - for a current line it's going to go and find a row in the table employees whose Manager id is equal to the employee id for the previous line.

  Good!  You already understand the most difficult part.

  In this case, CONNECT BY condition is

  Emp_id PRIOR = mgr_id

  This condition uses emp_id PREREQUISITE, which means that, when deciding if a line will join the game at the level of results = n, he's looking to see what the emp_ids are on LEVEL =(n-1).

  A line will join the LEVEL = 2 if its mgr_id is identical to a level 1 = emp_id.

  A line will join the LEVEL = 3 if its mgr_id is identical to a level 2 = emp_id

  A line will join the LEVEL = 4 if its mgr_id is identical to a level 3 = emp_id.

  ...

  and so on, until you reach a LEVEL where no line do not join.

  But I don't understand "CONNECT LEVEL <=> ?"

  In this case, CONNECT BY condition is just

  LEVEL<=>

  PRIOR is not used in this condition, which means that, when deciding if a line will join the game at the level of results = n, it is not all knowledge on what is on LEVEL =(n-1).

  A line will join the LEVEL = 2 if 2<=>

  A line will join the LEVEL = 3 if 3<=>

  A line will join the LEVEL = 4 If 4<=>

  ...

  and so on, until you reach a LEVEL where no line do not join (which will be LEVEL = 366).

• So I need a little help with the Flash colors

  I always use the red, green and blue gradient colors Flash below for metal stuff, but how do I get the effect of this red color in different colors like yellow?

  If you want to use predefined gradients, what you could do is the first color any field you want with one of them, and then select the fill and use the color Panel to replace the Red some other color you prefer.   If you have never worked with the degraded section of the color Panel, you will be probably it find a bettter tool to create and fine-tune transitions.

  

  You just doubleclick, this little red square in the lower left and it opens a color sample as you have demonstrated to select another color

• Little help to understand networks

  Hello

  I have little problems to understand some things about the networks and VMWare. I have ESX Server 3.5 on an HP 460c blade that has 2 network cards. Now I want to use virtual machines on 4 different networks, but to my knowledge, it should be 4 NETWORK cards. Our network guys tell me however that they can make the VLAN Trunking to make me able to use 4 hollow networks two network cards. I tried to look for books on this subject, most of them just confuses me more. So simple Yes or no question, can use 4 different networks with VLan trunking with ESX?

  If I can how can I configure the virtual switches? Just with different VLAN IDS?

  Yes.  You can have several different networks with your 2 NIC your network team is OK, all they need to do is configure the physical switch with trunking VLAN.  That means that they can add as many networks via VLAN ID, and all you have to do is create an a vswitch with multiple exchanges by VLAN ID.  For example, I vswitch (1) with discussions various (7) created this topic with the following VLAN 100, 110, 120, 130, etc, etc..

  I hope this helps!

• Help me understand the Vista backup

  I just started using Vista backup to backup my PC to an external hard drive.  There are several things I want to ask about the Vista Backup utility.

  1. with many other backup programs (by example, utility backup Windows XP), I was able to review what files were backed up, because the utility has a provision for the display of files saved in their original folder structure.  This is useful for manual checking that a group of files have been backed up.

  With Vista backup, there is no provision.  The backup is stored in a number of ZIP files, with no apparent match to the source folder structure.

  Is there another way to view files saved in their original Vista backup folder structure?

  2. I recently did a second backup of my hard drive Vista.  I have added almost all the files.  In fact, most of the changes have been moving and renaming of audio files.  Yet, the second backup is larger than the first, each approximately 20 GB.  And it took a long time, like the first.  Ultimately, the TWO backups were kept in separate folders dated.

  My questions:
  a. Why is the second big backup?  Can I apply an incremental, or differential backup as it existed under XP?  If you tell me that it's already a differential backup, then why is it so important and take so long?

  b. I must keep each date of the backup folder?  If so, my external hard drive is quickly running out of room!  But if I remove it, maybe I'll lose data!  Please help me understand how Vista backups are cataloged.

  Thank you.

  The second backup is great because because you moved your files autour and so backup if they were different files. Vista backup only new or modified files after the first backup.

  If you open the file, you will be able to access all the saved files and delete those you don't need.

• Help to understand the basics of the integration of Javascript/QML

  Hey all!

  I am just development of BB for the first time, so please bear with me. I'm not sure that understand the interaction between JS and QML. I understand that you can write JS in QML, particularly in managers of signals, and I used chunks of it with success. Also, I show/read by the "Javascript in QML" and JS linked in the pages of Qt, which helped a bit.

  However, I am having a few problems incorporating it into my code.  Could you take a look at this and point me in the right direction? (I'm also new to JS itself, so maybe that my mistakes are with this instead?)

  guideline += 'water '.

  }

  Return to the guideline;

  }

   

  
  Thanks in advance! I feel I'm missing something incredibly small/basic

  try calling it without braces.

  You can also create a function directly in QML, no need to export to a js file unless you want to use other components (that are not subcomponents) as well.

  to learn more about the construction of Qt/QML parent, I suggest to read this doc API:
  http://Qt-project.org/doc/Qt-4.8/objecttrees.html

  createObject (this) would create a new component with the parent defined on the object class, and if this is destroyed a new is also destroyed. This is useful when you create components dynamically as you don't have to delete them manually later.

• New curve blackBerry Smartphones user 9320, I need a little help

  9320 curve is my first Smartphone after an old style phone. I managed to understand the basics, texts, Internet access, etc. I need a bit of help with the rest, for example, I tried to download a free app, but get the error message 40721 - without put credentials cached.

  (A) what do I have to register my details somewhere to download (even free) applications, where and how?

  (B) I don't have a Blackberry ID, or more precisely do not know what is it.  How is it useful?

  Here are my most immediate questions, and I would appreciate a few basic instructions, where and how to...

  Thank you very much

  Hi Woundenberg

  I thing your carrier have not activated BlackBerry data Plan aka BIS on your account. BIS is different from a data plan normal, a normal data plan you will navigate on the internet but will not give access to the BlackBerry application. So I prefer to give you a call to T-Mobile for re - confirm whether or not they had allocated BIS on your account.

  When BlackBerry data plans are enabled on your device, and then click Manage connections > Service status > = BlackBerry Internet Service it will be " Mobile network ".

  Then call T - Mobile and let us know about your updates.

• Can someone help me understand the process Instance recovery

  First thanks for all of you who responded to my post, any help is really appreciated.
  
  I would like to more deeply understand the Instance recovery process then the Administration Guide of Oracle Docs can tell me.
  
  What I have so far of Instance recovery is:
  
  1 oracle determines which files are not synchronized.
  2. all data from redo log files is applied to restore log buffers by progression. Buffers do not participate on the database of normal transactions because they are marked to pick it up.
  All these data are applied to the data files (commited and contains transactions).
  This step is called roll forward.
  3 cancellation are used to restore transaction no. After this step the datafiles not aura no data contains on them. At this point, the instance is available for users, but the blocks used are not.
  4. all files are now in sync.
  
  My questions are:
  
  -Step 1, what process determines which files are not sync? Make the bed of Smon the controlfile and data file headers and then make a list which is not sync?
  
  -L' step 2, what is the process that reads the information in the redo log files and complete the recovery log buffer? What is the CKPT? And how he is warned that he might start to read the files after completing step 1? There is a semaphore that is defined for it?
  
  -Step 2, which process applies information engaged and contains buffer redo log for the data files? When it starts to apply this information of the instance is already partially available to users?
  
  -Step 3, what is the process that reads up to cancel to restore transactions not? This process must be done once step 2 is complete as could be blocks of the undo tablespace on buffers of the right-wing newspaper do it again? And when this step 3 starts, the process is triggered by an another semaphore?
  
  -When step 3 is finished, what process changes the State of the database of partially open to open, or that's just what we call it when the database has always revenge marked for recovery?
  
  Thanks again in advance for the help, there are reasons not practice known this information, I'm just a curious person who could not find this information on the google...
  
  
  Ricardo Rodriguez

  Ricardo,
  Well, I'll take a chance to respond.
  (1) SMON in the start-up phase, in the strict sense in the editing phase, compares the SNA stored in the control file with the data file headers. This sCN is called checkpoint SCN. It is always higher among the controlfile so its part of the same database and is not set up to an old backup. By this correspondence, Oralce comes to know that there are some report files with their SNA control point is only not with the controlfile and consequently, instance recovery is reported. Here is the list of files is prepared.
  (2) the same process SMON only would trigger playback of the redo log files and launch the Rollforward process. Roll forward is made from the last address bytes redo controlled at the end of the restore log forward. This means that the last block, blocks have not reported in the data file are simply read and are dumped on the data files. As a result, we get a situation that the data file will end up with a lot of data committed but also committed that redo is containing both.
  CKPT process will not come in the picture I think. Where did you read what CKPT would do all this?
  (3) SMON governs all this thing is to say the application of the data for the data files. No, in this phase, we are still in the phase of mounting that this recovery is called crash recovery. Oracle wouldn't let users to use the database at this point. Data is still not available for them.
  (4) do not bring semaphores here. They are already in use when you allocated the memory of your instnace. Its work process level. After the mount phase is completed, oracle would open up the db. At this stage, "the transaction recovery" aka rear roller phase. That would be launched to relax all the operations that are not validated.
  Now to do this, undo will be used. Oracle launches this phase into two or more strictly speaking 3 ways. One, SMON would just check how many blocks will be there for the recovery. If they are larger, it would begin the rear roller with parallel slaves. This is called "we demand" rollback. It is initiated by the user. So if you were using the EMP table data and the server crashed between, now the next time you start, if you try to access the same blocks once again, they are set aside on the basis of priority.
  The third one will rollback transaction intra. It's basically splitting the work among the slaves so that if a slave is sitting free, it can share the work and can move forward to make things more quickly restored.
  Please note that all this is happening at the open stage. This means then that this is the case, oracle is available for users. And second, there is little change in this process (an integer) 9i go. This is called two-pass recovery which has been made to make this process a little faster. In this regard, SMON ignores these blocks that are controlled by DBWR during execution of the phase of rollforward.
  Hope this makes some sense and helps. Let me know if there is something wrong or unclear.

• Need help to understand the security sandbox problem after changing Web host

  I am trying to switch my Web host 1 & 1 shared hosting to an IP address with a small company that specializes in Drupal sites and doesn't know much about flash dedicated.

  1 & 1 is always the Registrar for my domain, but I 'tidied up' YourGods.com on holistic servers and "stressed" my site DomainNameServers holistic rather than servers 1 & 1.

  After doing this, my Flash site (which is based on the Gaia framework) has stopped working, and the Flashplayer debugger, gave me the following errors:

  Error: Cannot load the xmlsocket://127.0.0.1:5800 policy file

  Error: Request for resource at the xmlsocket://127.0.0.1:5800 by the http://www.yourgods.com/bin/main.swf applicant failed because the server is not reachable.

  Security Sandbox Violation

  Connection to 127.0.0.1:5800 broken - not allowed to http://www.yourgods.com/bin/main.swf

  Someone to help me on another thread thought 127.0.0.1:5800 could mean that the problem had to do with my ways and I tried to access something on my local computer, rather than being a matter of cross-domain standard where one server was attempting to access files on another server without report.

  If anyone can clarify this?

  I googled 127.0.0.1:5800 and found some stuff on the loops between a server and the original computer, but I don't really know how to put it all together.

  Is it possible (with the flash debugger or other software) to step through my code actionscript with periodic break points so I can understand which line is causing the problem?

  Or a way to find out if there is a problem between holistic and my local or holistic computer and the 1 & 1 servers?

  Thanks for any help.

  127.0.0.1 is your local development server. It seems that your application is trying to access this IP address and unable to. You need to look at the source and find where it accesses to this and replace it with the IP address.

• need help to understand the ACLs and security levels

  I use static NAT (nat (inside, outside) static interface) between a single host inside for the DHCP address used on the external interface. The inside interface has the security level of 100, and the outside has the security level of 0. My understanding is that for connections with State, I wouldn't need the ACL. However, nothing works unless I set up an ACL (for example, right now I have a global allow rule). What Miss me?

  Even if you 'dormant', but you still have the access list applied on the interface which, by default, will have the "deny ip any any" implicitly at the end of the access eventhough list you have existing line "inactive".

  To remove access from the inside of the interface completely list, you must remove the following line:
