Explain the balloon in my scenario

Hello

Can you guys explain values associated with memory, I know that we have documentation, but it is difficult to digest. (Seescreenshot)

I have a virtual machine with 2 vCPU and 4 GB of vRAM

I put resources on the memory limit to 1 024 MB and after that I got the following error "memory usage high ball for UPIDSDWebTest has been replaced by mistake (previous state: warning).

Then I changed the limit to 3 GB. Do not see the error, but still hot-air balloon.

In other words, what is the purpose of limitation?

In other words, what is the purpose of limitation?

An example: consider your boss wants to have a VM for his own use with 16 GB of memory. You assign 16 GB memory (this is what the guest operating system will see) but limit to 2 GB memory (because you know that it will not need 16 GB anyway)

Seriously, I don't see a case of actual use for the memory limits. What I think is an environment where users are charged for the use of the memory physics, but need option to increase dynamically without downtime for the virtual machine (that is, the virtual machine does not support hot-add memory).

  • The guest with the balloon pilot can inflate itself?

    The guest with the balloon pilot can inflate itself?

    as the topic.

    Yes, everything you said is true. With technical virtualization inplace, we always try to approve it at 1.5 x or 2 x take an example that will make this much clearer scenario.

    As you have a host with 8 GB of memory and you have turned on on four virtual machines each with 4 GB which is overcommitment of X 2. To achieve this level of overcommitment VMkernel uses now several technique of reclaimation of Page like:

    Page sharing

    Balloon flight

    Compression

    and Exchange.

    There may be a case when high memory pressure is VM1 and VM2 is lightly loaded, in this case balloon pilot will inflate in VM2 and pass the memory address to VMkernel which in turn pass these addresses at VM1. Don't forget THAT VM is completely uinaware in all these transition. Once the need has been filled the balloon VM2 pilot deflate and recover his memory.

    Please note that the balloon pilot is nothing but a program that uses the system call named Malloc() to reserve memory.

  • HP Laserjet Pro M201dw: "then I explained the problem to management and they said not to buy all the HP printers more."

    Our two new printers Laserjet Pro M201dw are not recognized on the office network.   I have spent hours trying to understand this and posted questions on the forum Support HP, but without response. They became more disadvantages than thay are worth.  And that's enough.  Then I explained the problem to management and they said 'don't buy it not all HP printers more.'

    Thanks for the suggestions.

    I tried to BootP and disable ipv6 on a printer and at first, it worked (finally).  But then, after having unplugged and restarted, he returned to the ip address of connection no.

    So finally, I noticed and changed the setting of the link of "Automatic" to '100TX' speed full - and that seems to have solved the problem of intermittency.  I've converted and turn it back on, unplugged, etc., and it maintains the connection and ip address.

    Do not want to play with something that works, I can't say with certainty if the speed of one link would have solved the problem (probably not), but it seems that while your excellent suggestions finally established a network connection, the setting of explicit link speed was necessary to maintain the connection.

    Thanks for your help in this matter!

  • How to explain the error in the executable file?

    As everyone knows, there are 3 parts to the cluster of error: status and source code. The State's flag, the code is the error code and the source is where Labview think that the error occurred. Normally, when I'm in the environment labview course I can just right mouse click the error and click "explain the error" and a description and detailed error possible cause rises.

    However, when I create an executable I don't know how to explain the error to the user, such as labview.

    When an error occurs that I wish I had a popup that says code error, source and EXPLANATION. The code and the only source is so enigmatic sound quite panic inducing the user, whether or not the error is unrecoverable/crash-inducing. Also this would save me having to search the online error code.

    How to make the explanation of the error code? There is a vi that I can enter an error code and get the explanation string?

    There is probably something simple I forget but I couldn't find the answer in my research. Thanks in advance for your help.

  • Explain the explain plan

    decide to move to optimization soon. Book says join faster that the subquery in this example because the analyses involved. The "cost" to the subquery appears lower than the cost for the join. So it is confusing to me - aka How should I be interpreting this.

    Plan of subquery:

    image2.png.jpg

    join plan

    image2.png.jpg

    as you can see that the plan for the subquery has less than a cost. Could someone explain these outputs as to which application is more effective. I need to start somewhere.

    Thank you!

    The BEST way to get help when you ask questions is:

    1 ask questions on SPECIFIC things

    2. tell us EXACTLY what term, value, etc. ask abaout

    Book says join faster that the subquery in this example because the analyses involved. The "cost" to the subquery appears lower than the cost for the join. So it is confusing to me - aka How should I be interpreting this.

    OK - what BOOK are you talking about? There is not much interest to mention a book if you're not going to tell us which book it and provide a link to it and even a page number. This gives us the SCOPE of your question.

    This "cost for the subquery" are you talking about? Be specifc. It is in one of the plans that you posted? What plan? Whose cost is it? For example, you could say:

    I have a question for the foreground below. Why is the cost to the xx line lower than the cost of the second plan on line AA?

    This question refers CLEARLY to the info we're talking. The way in which you stating the question, we try to guess what plan and the lines you want to say.

    subquery plan:
    
    
    join plan
    
    
    as you can see the subquery plan has less of a cost. Could someone explain from these outputs as to which query is more efficient. I need to start from somewhere.
    

    Are you talking about line #1 in each of these plans?

    Please edit your post and tell us EXACTLY what you ask in the topic and refer to values and SPECIFIC lines. Also post a link to the book and a reference to a page number you got the information from.

    The optimizer generally chooses the REAL implementation with the lowest cost plan. It is not clear whether the plans that you have posted are ACTUAL spending plans that Oracle really determined and used or just explain plans.for what Oracle thought it might use.

    If the statistics are not up-to-date these plans do not yet reflect the reality of the data.

    And if the amount of data is a small number of blocks or other of these plans can run better than the other in reality.

    You can find this Oracle white paper "Explain the Plan explaining" useful

  • Question about cardinality (lines) to explain the plan

    I have two tables (names have been changed to protect the innocent):


    TABLE 1:


    The Null columns?    Type

    -------------------- -------- ----------------------------------------------

    Table1_Primary_Key NOT NULL NUMBER

    more than 10 columns


    TABLE2:


    The Null columns?    Type

    -------------------- -------- ----------------------------------------------

    Table2_Primary_Key NOT NULL NUMBER

    more than 8 columns


    Lines of table1 has 1097172


    Rows of table2 has 160960


    I am analysis request and get explain below:


    SELECT t1. Table1_Primary_Key

    --

    FROM TABLE1 t1,

    From TABLE2 T2

    --

    WHERE t1. Table1_Primary_Key = t1. Table1_Primary_Key

    AND t2. Table2_Primary_Key = 3432798

    /


    ------------------------------------------------------------------------------------------------

    | ID | Operation | Name | Lines | Bytes | Cost (% CPU). Time |

    |*  5 |    INDEX UNIQUE SCAN | TABLE1_PK |     1.       |     1 (0) | 00:00:01 |

    ------------------------------------------------------------------------------------------------


    As you can see it table2 is exactly 1 row and join table1 on a correspondence of single line.


    My question is this:


    Why the plan of the explain command seems (at least for me) to indicate that it looked like all the rows in TABLE1?


    Thank you

    the optimizer's decisions are based on the object (and maybe system) statistics: so it's a good idea to provide as much information as possible in these statistics. Basically, there is nothing wrong with statistics automatic collection job - so I would count on that if I don't have very good reason to use anything else. Of course, there are some situations in which it's a good idea to add a few adjustions for automatic collection: sometimes, there is too much created histograms, sometimes there is too little (basically you have histograms when the distribution of the data is not yet). And if there are columns with correlated values who serve together in boundary conditions then create extensive statistics may be a good idea. To make these adjustions, you can use the routines of pref dbms_stats. And sometimes, it may even be a good idea is not to collect statistics for an object and use the sample dynamic (dynamic statistics) for more detailed information on the cardinality of distribution and join.

    In the book of my opinion Jonathan Lewis cost base Oracle Fundamentals still contains the best explanation of the use of optimizer statistics - and Christian Antognini Oracle performance troubleshooting also provides a lot of valuable information about statistics and their gathering. Of course the documentation also explains the basics in detail: Managing optimizer statistics - 11 g Release 2 (11.2). And if you want to get a shorter summary, then you can always take a look at the Web of Tim Hall site: https://oracle-base.com/articles/misc/cost-based-optimizer-and-database-statistics.

    I am ok for that but active only plans is right, but in accordance with the foregoing, two data line table in the table SQL V$ so both active and plan cost is high and the other is low.

    Yes that's right cost is different, he means here another effective plan for oracle will analyze the declaration again and stored as new slider of the child. Especially since I explained that.
