What's the meaning of these information?

I use java -verbose:gc to run MyApp, and there are two information displayed on the console.
[GC 905K->905K(1984K), 0.0198318 secs]
[Full GC 945K->944K(2152K), 0.0497921 secs]
what's the every part's meaning of these information?

It is providing verbose information on the Garbage Collector. Like how big the JVM memory footprint was before and after Garbage Collection, and how long it took.

  • Could you tell me what's the meaning of the logfile-path and log-level?

    we are running an productive xml database. but it is not stable now. Sometime it would report resource conflict error while you access xmldb via http protocol. I read the database logs and listener logs, but no abnormal message could be found. So, I want to find more information from the xmldb logs. While I run select DBMS_XDB.cfg_get().getclobval() from dual, I found that there are several logfile-path and log-level tags and I guess that these would be xmldb logs. Does anyone know what's the meaning of these tags?

    I wondered about that one often too. I didn't have a chance yet to investigate (but maybe Mark will elaborate a little here), my guess is that it / or will be a possibility to enable tracing regarding the protocols or servlets.
    Though It look like if you enable it it will trace to the XML file defined in the xdbconfig.xml. I also guess that (because there is also a XSD counterpart) that one could create an resource that streams the errors into a XDB ftp or http or ... xmltype table based on these settings.
    This would be great because it would mature the protocol server regarding functionality. You could enable the tracing and see what happens. Until now the documentation doesn't give much extra insight...

  • What is the meaning of partition by statistics

    Hi All
    What is the meaning of partition by statistics ?
    I could not grasp it meaning.
    I have a fact table that has about 2.8 million records and around 8 dimensions
    I currently am parititioning it by time as each time period has equal number of records

    Murtuza:
    Certain processes generate postings above and beyond the entered information, eg. cash discounts or rounding etc.  these internally generated items are posting relevant but were not entered by user/transaction.  in this way that flag identifies the cause for the posting.

    Hi,
    I am not sure that link dealt with issue.
    <b><u>i.</u></b> For example,
    it points out that “RKF/selection Elements are stored in RSZSELECT” but when I take one of my  restricted key figures (ZRKFxxx2) and search through the table RSZSELECT in se16, I can find this restricted key figure.
    <b><u>ii.</u></b> For example,
    it points out that the “CKF/Formula Elements are stored in RSZCALC” but in se16, rszcalc gives info such as below which does not reveal formula and not much meaning just as my initial post:

  • In CM01 selection screen, what is the meaning of "Operator"

    Hello,
    (1) In CM01 selection screen, there are 3 fields with column heading "Operator". There is no documentation available for those fields. Can someone help me understand what is the meaning and use of those 3 fields. Thanks.
    (2) We are in the process of writing a wrapper program for CM01 - so that we have more detailed selection options and also download to Excel. Any help/suggestion for this is welcomed. Thanks.
    - Chetan

    Hi Chetan
    the operator field is just to select your input values and it has these following options
    and has no significance on the report
    =     equal to
    <>     not equal to
    >     Greater than
    >=     greater than/equal to
    <     less than
    <=     less than/equal to
    EQ     equal to
    NE     not equal to
    GT     Greater than
    GE     greater than/equal to
    LT     less than
    LE     less than/equal to
    CP     contains pattern
    NP     does not contain pattern
    regarding downloading the report to excel file, it is a standard functionality and any ABAP developer should be able to add it to your report and if you plan to add some additional fields to make your report more details, you need to do some enhance ment and build a custom report depending on what you want to add
    if helpful please reward your points

  • What's the meaning of the various .bin files used by SAM?

    hey everyone,
    I'm trying to understand why exactly there are so many .bin files used by the SAM, and how to compile each one of them.
    My .rc file for the simulation contains:
    load bin reset.bin 0xfff0000000
    load bin q.bin 0xfff0010000
    load bin openboot.bin 0xfff0080000
    load bin nvram1 0x1f11000000
    load bin 1c1t-md.bin 0x100000
    load bin 1c1t-hv.bin 0x180000
    load bin disk1.img 0x1f40000000
    I don't understand why I have 3 different files - reset.bin, q.bin and openboot.bin when I would have expected only one bootfile.
    I also don't know what's the meaning of the 1c1t-md.bin file (what md stands for).
    If anyone could clear this subject for me, and also point me to the sources of each such file (if they exist in the project, and assume they do, at least for most of them), I'd be grateful.
    Thanks,
    Mintz Yuval

    Hi,
    Sorry I haven't replied sooner.
    I get your project now and it sounds pretty cool.
    Let me answer your last question first. The service processor resides a separate motherboard running independently of the N2 processor. The SP and N2 processor communicate via a I2C link which allows the SP to read and alter the state of the N2. The cpu, caches, NIU, memory, etc. are all connected by this link. Once the N2 is running, the SP and the N2 firmware may exchange messages via a mailbox protocol over the I2C.
    nvram1.bin is a configuration file that is OBP specific. On HW, it would be a little ROM that obp reads during the boot. Since it's in memory, SAM doesn't make any assumptions about it. You can remove it or rework it to suit u-boot.
    disk.img is the contents of a virtual disk which contains the root filesystem. This is essentially a ram disk which has been added to SAM's version of the hypervisor and/or obp. On HW, the firmware does not support this kind of virtual ram disk. For SAM, I'm pretty sure that obp is extended to create a device tree node for the virtual disk. Hypervisor may not know about the virtual disk.
    Since disk.img is a UFS (or other Solaris-oriented) filesystem, you will probably want to replace it with a ext3 or Linux-oriented filesystem. Since Linux has direct kernel support for ramdisk, you might be able to build/configure the kernel with the location of the root filesystem image in memory. Or this might be a u-boot option.
    As to 1c1t*.bin and reset.bin. On HW, the service processor is responsible for discovering all the devices and cpus on a system and writing the machine description file (e.g. 1c1t*.bin) and the reset firmware (e.g. reset.bin). These files are used during boot and various resets to initialize or reinitialize machines state for the cpus and all the i/o devices. Since SAM doesn't include a service processor, these files are static and created completely outside of SAM. The md*.bin files contents must match the configuration of cpu's in the sam.rc file -- firmware will fail if it tries to run code on a strand that is missing.
    The md and reset.bin files are used during the boot process to set-up CMT registers and do a little bit of i/o device initialization. SAM doesn't support reset modes such as warm reset.
    I hope this helps. Let me know if you need me to track down more details.
    Cheers,
    Stephen

  • What's the meaning of local PO, reservation?

    Hi ,
    I am new to SRM. I have small doubts. Please clarify these..
    1. Create the sc with 4 line items like this:
    i. line item one will be selected from the catalogue and will create a backend PO
    ii. line item two will be selected from the catalogue and will create a local PO
    iii.line item three will be entered manually and will create a backend PO
    iv. line item four will be a product that was replicated earlier and will create a reservation in the backend.
    I have to create a this type of SC.
    My doubt is:
    i. How i will come to know for this  SC,  PO will create in backend or PO will create in local??
    What is the meaning of local PO??
    ii. What's the meaning of reservation??
    As per my knowledge if it is a stock item resevations created. but i am not understanding exactly.
    Please explain me. I know these are very basic, but i am not understanding.
    Thanks,
    Visu

    This may be better posted in a different forum.
    I think in your case local = SRM, Backend = ERP (R/3, ECC).
    Reservation in this context is a step before PO, you can create a reservation to simulate values, it can later be converted into a PO.

  • What is the meaning of the dotted circle next to a song on a playlist?

    Why is there a dotted circle next to certain songs on a playlist that reflect on my iPhone on iTunes and these same songs after syncing are not reflecting on my iPhone?

    What is the meaning of this -
    Object[] x = {new String[]{"a","b"}};
    I have a function which takes Object[] as a argument.
    And I have data structure like this -
    Name = Zoolander
    Name = Hansel
    Name = Mugatu
    I am not interested in the Name part. This has to be
    converted to - Object[] x = {new String[]{"a","b"}}
    It works if I hard code the values like this -
    Object[] x = {new
    String[]{"Zoolander","Hansel","Mugatu"};
    Thanks in advanceI don't think you need the outer set of braces:String[] x = new String[]{"x","y","z"};will work, and does exactly what you expect it to do.

  • My iTunes list of downloaded TV programmes says 'Caution' next to some of them. What does this mean? These are programmes I've had for several months

    My iTunes list of downloaded TV programmes says 'Caution' next to some of them. What does this mean? These are programmes I've had for several months

    This is the Rating - the equivalent of the rating that you would have for a film (PG, 12, 15 etc)
    Britain does not have a TV rating system equivalent to this - like they have in America. TV shows you download with adult content may be rated caution. You can't then restrict access to them using itunes or device parental controls.
    There is no way as far as I know in iTunes to change the rating. You have to do this with a third party tagging application.

  • What is the difference between these two sticks of RAM?

    I am upgrading my Macbook 2.2 GHz Intel Core 2 duo from 2GB of ram to 4GB
    What is the difference between these two kits?
    4GB Kit (2 x 2GB) 200 Pin DDR2-667 PC2-5300 256x64 CL5 1.8V SODIMM ($102.00)
    4GB Kit (2 x 2GB) eRam 200 Pin DDR2-667 PC2-5300 CL5 1.8V SODIMM ($88.00)

    Probably nothing of any consequence. Some places can just negotiate better deals with suppliers. Or one of a million other factors that can affect price is in play here.
    When buying RAM, I generally find it's better to pay a little extra to get a brand that's known for quality. I usually stick to Crucial myself. If you look around, you can probably find some real steals out there, but I don't know... With stories of people who literally go dumpster diving, salvaging stuff that was slated for disposal, then turning around and selling it... I prefer not to take chances. If you are, by all means, go for the cheaper one.
