What size of database can support ten times to the maximum?

Masters.


What size of database arguably ten times now? or just varies according to the size of the physical memory?

I saw just ten times online docs, but I found no valuable index.


could you please guide me in the right direction.

Thank you

As Jeremy mentioned, there is no built-in limit on the overall database size. It's really dependent on the material, mainly the memory capacity and the drive capacity/performance. We have at least a data store > 1 TB deployed in production, but encountered the most common size is in the 10s of GB range with a few in the 100s of the GB range.

The main challenge with very large databases in memory are some of the management, before any startup/recovery operations, stop and, if you use replication, duplicate. These can take a long time to complete, even with good discs.

For example, consider a 1 TB (1024 GB, 1 048 576 MB) data store running on a disk system RAID-0 that can maintain 100 MB/s sequential transfer rate (a midrange disk subsystem). In this case a clean boot (without recovery) will take at least 1048576 / 100 seconds = 10 486 seconds = 175 minutes = 2 hours and 55 minutes. for example, it will take nearly 3 hours to bring up the data store. If the recovery is necessary 9e.g. after a failure), then it will take more time. In a replicated environment a double operation speed may well be limited by the network (depending on the type of local network) and so a duplicate of this data store could easily take longer than 3 hours in certain circumstances (but using the--compress option and a high bandwidth LAN will help compensate for that).

    I have received and read your private message. Yes, you can install 8 GB + 4 GB (current module). They will work at 1600 instead of 800 MHz (single channel). You will see the difference!

    Here are the compatible memory modules:

    If you have the budget, I recommend buying a set of 16 GB (2x8Gb).

    The upgrade and maintenance Guide
    http://h10032.www1.HP.com/CTG/manual/c01835715.PDF

    NOTE: The ATX Standard PSU is 86 mm height; Width 150mm; 140 mm in length (ATX12V version 2.3 March 2007).
    Third party PSU manufacturers extend the length of Dimension (150mm to 200mm) of high power PSU.

    MEASURE your clearances (for the son out of DC power in case) berries CD/DVD media at this level in case, just in front of the PSU.
    You will find some ATX compatible (140 mm in length) up to about 600 Watts PSU, 160 mm is common with more than 600W POWER supply.

    IF you are thinking of the future motherboard swap (Haswell or higher), make sure your power supply is compatible with the new C6/C7 (Haswell/Broadwell) mode.

  • If you use SSD what size minimum, you can use I'll just install the softwar winds 7 operation and put all the other programs on a hard drive Sata is the way it should be done?

Could someone ' a please advise please.

    The minimum I recommend is 80 GB, if you can go for 128 GB to 160 GB, I would go for it.

    Windows 7 uses 10 GB of disk space, and you have to take into account future, Service Packs and updates.

    You must also consider your page file size that will depend on the amount of RAM you have installed.

    Other disk space requirements include your programs and hardware drivers.

    The benefits of having an SSD is to accelerate the performance of the operating system and applications. In order to have a just installed SSD for upgrading the operating system on a mechanical HDD as well as your programs wouldn't make sense. Store content or data that you create on the HARD disk.

  • What views of $ v can I use to monitor the parallel process?

    Hi all

    The version of DB is 11.1.

    I ran a sql in parallel. And I got the SessionID for the session.

    But when I referred to v$ px_session, v$ px_process or sql_monitor $ v even with this session id, I have nothing from these points of view.

    The exectuion plan showed that it used parallel exectuion.

    Could someone tell me what is the problem with my approach? Or it means that my sql has not used the parallel at all?

    Best regards
    Leon

    PARALLEL_MAX_SERVERS to 0 for the database instance. Confirm that there are no PX processes running on the instance of database (these would be process "ora_p0xx_SID", where xx is 00 to 99 (or 128)) on the server.

    Then set PARALLEL_MAX_SERVERS to 8 or 16 or more.

    Run your query/dml.

    Now, see if the ora_p0xx_SID process has created.

  • The maximum size of the default packages in 3.7.0.1

    Hello

    Looks like there is another reason to do a full restart of cluster to apply the first patch for 3.7 (3.7.0.1). On a machine with MTU = 1500, it seems that the default maximum packet size value is passed from 1452 to 65535 and this change prevents the cluster to form during a rolling upgrade.

    See you soon,.
    Alexey

    Alexey salvation,

    Yes, the maximum packet size by default for 3.7 was believed to have been 65535, however there is a bug that prevented this work. 3.7.0.1 solves this problem and therefore "presents" the new default higher. A rolling restart is always possible, however, you need to manually configure the maximum to be 1468. The new maximum 65535 allows default configuration of coherence in support of large groups (greater then ~ 450 JVMs), where old default configuration would prevent new members joining and would require a reconfiguration and a full reboot.

    Thank you

    Hey Buddy,

    You can answer this question yourself!

    I checked the specifications of this laptop on the Toshiba site and you can upgrade the RAM 8 GB. Therefore, you (1 066 MHz) DDR3 RAM and two 4 GB modules. They should be the same manufacturing to avoid problems of incompatibility.

    Thank you
    Meg

    Meg,

    You can definitely show text exceeds the maximum allowed in Word.

    • Open a new Word document
    • Set the Page layout > landscape
    • Select your font > set size 72 (max in 2013 Word) or anything that is the maximum for your version of Word
    • Cut the text > save as a .jpg file
    • Insert the image file in your Word document
    • Right click on the inserted picture > select the size and Position > increase the size of the image to any percentage you like

    Because the 'text' is now captured in the image, it will display as the size of the 'bigger '.
