Oracle and the SSDS

Hello

We have a database of 3 TB and in a few months with migrating to a SAN storage 8 TB of HP with SAS 15 K disks nine. I have no idea how the disks are configured, but the faster they are RAID 0 + 1. Of course, this system is a data warehouse. The vast majority of reports must be run on about 150 GB of data most recently added. The system includes 8 PA-RISC processors and 16 GB of RAM, but we could opt for Oracle RAC with 3 these systems (instead of 1 we use now).

Is could someone please tell me if the SSD will offer all the advantages of this system? If so, what are we supposed to do? Tablespace Temp? Redo logs? Archive logs? Request for verification of output? Let's keep each month in its own tablespace and I thought maybe we could welcome the current month, where almost all reports are ran, in the SSD and at the end of the month move it to the HARD drive-based SAN storage. This configuration is feasible or is it too complicated for a vital production environment?

Thank you.

restructuring of the database to make the best use of the SSD

Not necessary, if you map your data o tablrespaces files correctly.

Just move data I/O files on the SSD, no restructuring device is necessary.

I wanted the opinion of someone who has had experience with SSD and Oracle first hand.

And you mine. I've used SSD for four years, love them! I have a database of 80 GB and SSD relief runns full fast.

    Hello I have a new problem xD maybe not so great :)

    I bought Mushkin SSD 240 B speed Delux Calisto is 285/275...

    Btw2... I want to crypt my SSD with TrueCrypt 7. 0 has... How this decrease my SSD speed if anyone knows.

    Thank you to all who help me, final problem that I put on this forum has been resolved because nice people :) all ty!

    Hey,.

    Of course you can test it with your own installation of Windows, but I doubt it s a problem with the operating system preinstalled Toshiba. I mean this image is tested and configured for your laptop

    In your case, I would also check the version of the firmware of your SSD. There may be an update for it.

    Also, make sure that the version of the BIOS of your laptop is newer.

  • ALTER Table of the default Oracle and the length of name of column Type

    Hi all

    I want to increase the length of the table names and the names of the columns in Oracle.

    By default, it is set like this:

    SQL > dba_tab_columns desc;

    TABLE_NAME NOT NULL VARCHAR2 (30)
    COLUMN_NAME NOT NULL VARCHAR2 (30)
    ...

    Is it possible to change the VARCHAR2 (30) to VARCHAR2 (100)?

    Published by: sukrandere on 12:21 10.Mar.2010

    Table names and column are all two identifiers
    According to the documentation, the maximum length of an identifier is 30 characters.
    It is hard coded in the database software and you can't change it.
    Or do you need to change.

    Hi all.

    The db Oracle will essentially the size of block 8 k value. The oracle block size must be synchronized with the size of the minimum of 16 k segment?
    How this change may affect performance?
    Thank you.

  • Is Oracle and the Developer installation reports

    Hello

    It seems that the Internet Developer Suite 10g (10.1.2.0.2) installer allows us only to install the complete set of tools that is Oracle Forms Developer, Oracle Designer, Oracle Reports Developer and Oracle10g JDeveloper and we cannot do a custom install which either we would just install forms and reports or to remove install station Designer and JDeveloper.
    Is there another way to install only the tools forms and reports?

    Any help or advice would be appreciated.

    Thank you

  • Import of Oracle and the export utility

    Hi all

    Could someone please explain me Oracle Import and Export Utility. I went through the link below and it was mentioned to use the keyword "exp" but I don't get any idea where to use. To explain the functioning of the util.

    Hello;

    Export creates a logical backup its great to move the tables, diagrams, etc.

    Import bring data back in.

    You can use a parm file with either.

    Example of import:

    IMP parfile = in .parm

    in.parm ( contains )
    
    userid=system/
    fromuser=scott
    touser=scott
    file=in.dmp
    log=in.log
    

    parfile = out .parm of EMP

    out.parm ( contains )
    
    userid=system/
    owner=scott
    file=out.dmp
    log=out.dmp
    statistics=none
    

    You can use these commands at the operating system level to get quick help.

    imp help=y
    
    enp help=y
    

    You can export a subset of a table:

    exp scott/t tables=emp query="where deptno=20"
    

    You can use options like:

    full=y
    BUFFER=2000000
    GRANTS=y
    COMPRESS=y
    

    This utility is replaced by the data pump.

  • Captian El is not installed on the SSD disk fusion part after recovering from the internet

    I found that my Mac OS X El Captian is installed on the part of the hard disk of 1 TB disk fusion rather than the part of the SSD drive after the installation of recovery of the internet.

    And the SSD disk fusion part seems to be "not fitted"...

    May I ask if this is correct?

    I saw on the article depending on whether recovery facility will automatically take care of the promenade of the merger and put the files system on the part of the reader Flash memory:

    http://www.PCMag.com/Article2/0, 2817,2412726,00.asp

    If my drive information below is not correct, do the following:

    1. partition SSD disk fusion part and

    2. Mount and

    3. repeat to Install OS X on this SSD part internet recovery rather than the part of the hard drive of my 1 TB drive

    Your opinion is greatly appreciated!

    Should not be only one Macintosh HD picture to the choice at the start?

  • Organizing files on the SSD and HDD

    Hello

    According to me, there are answers to this, but I found them a bit too technical and advanced for my level of knowledge.

    I have a 250 GB SSD and a 1 TB HARD drive and am looking for the best way to structure my work FCPX (the SSD is too small to store everything). The application is installed on the SSD, which I suppose is the best for performance. I recently discovered the properties of the library menu and set it to store media and backups on my HARD drive, but the Cache on my SSD. I don't really know if it's the best - any help would be greatly appreciated. Thank you!

  • Installation of SSD drive and the noise of the fan to the MacBook Pro?

    Hello

    Just replaced the stock 5400 RPM HARD drive in my MacBook Pro mid-2012 with an SSD 480 GB Sandisk and now the fan makes a loud noise. Sounds like it's revving at full speed. Does anyone know how to fix this?

    Thank you.

    You can try Macs with Intel processors: System management controller (SMC) reset and see if that fixes the problem. Unless you make a mistake in the reassembly, the two should be independent. On the other hand, it could be something in the design of the SSD. Personally, I would like to replace it with an OWC or OCZ.

    To check if the two are somehow connected try to replace the old HDD to see if the fan slows down. If it then reinstalls the SSD, making attention to do correctly and re - test. See how to install the ribbon cable short connecting the drive to the motherboard. It's easy to get the pins on the misaligned ribbon cable.

  • The SSD and RAM upgrade

    I have the 13-inch Retina Display early 2015 model. It contains 128 GB SSD and 8 GB of RAM.

    I wanted to update both of them. Is this possible? I agree with HARD drive even if that is supported. 128 GB is not enough for me actually.

    Help, please.

    Without the SSD and RAM are both not upgradable.

    One option is to sell your computer and use the money to buy a new one with the features you need.

    There are two options to add an HD card to your card HD slot. Both options will be flush with the case.
