Import is very Slow with xmltype column in oracle 9.2.0.7

Hi
We are using oracle 9.2.0.7 on Solaris
The import without XMLTYPE column is faster the import of the table with XMLTYPE column.Also when we do the export in direct path it is still going for Conventional(I suppose this is correct for XMLTYPE).
Is this the general behaviour of XMLTYPE...if so how to improve the performance of the import.
Can anybody help us out in resolving the issue.

here is the output

  • AE CS6 very slow with footage

    Hi guys,
    I am using AE Effects CS6 (11.0.4.2) on a new Macbook Pro with these specs:
    2.8 GHz Intel Core i5
    16 GB MHz DDR3
    Intel Iris 1536 MB
    The problem I am having is that when imported footage is visible as footage or a layer, AE becomes very slow with every click of the mouse on either the timeline or the footage in the viewer itself causing the color wheel to appear, often for 30 seconds at a time. Strangely, dealing with the composition has no issues.
    Any ideas guys?
    Thanks in advance

    Try transcoding the footage to a production codec and see if that makes a difference.
    Like, use the Adobe Media Encoder to make them something like QuickTime with the PhotoJPEG codec.
    See if that helps with the performance.

    My macbook pro is running very slow with some strange mouse and window movements. The trackpad is very unresponsive and when responding the cursor moves on its own and/or very erratically. When on safari the window suddenly zooms in or highlights words and looks them up via dictionary. I currently have a wireless mouse connected and I am still having the same problems.
    I fee like I may have a virus or my laptop is perhaps being accessed remotely. All of the sharing options are unchecked.
    HELP PLEASE
    Very worried!!

    Try these in order testing your system after each to see if it's back to normal:
    1. a. Resetting your Mac's PRAM and NVRAM
        b. Intel-based Macs: Resetting the System Management Controller (SMC)
    2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
         Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
         COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and
         after the chime press and hold down the OPTION key until the boot manager screen appears.
         Select the Recovery HD and click on the downward pointing arrow button.
    3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
         Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).
    4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).

  • Importing From Flat File with Dynamic Columns

    HI
    I am using ssis 2008,i have folder in which I have Four(4) “.txt” files each file will have 2 columns(ID, NAME). I loaded 4
    files in one destination, but today I receive one more “.txt” file here we have 3 columns (ID, NAME, JOB) how can I get a message new column will receive in source. And how can I create in extra column in my destination table dynamically …please help me

    Hi Sasidhar,
    You need a Script Task to read the names and number of columns in the first row of the flat file each time and store it in a variable, then create a staging table dynamically based on this variable and modify the destination table definition if one ore more
    new columns need to be added, and then use the staging table to load the destination table. I am afraid there is no available working script for your scenario, and you need some .NET coding experience to achieve your goal. Here is an example you can refer
    to:

    Mail starts normal, though that is also somewhat slow,
    Before it has finished downloading mail (even is there os no mail!) it takes sometimes 2 minutes!
    Also there was no"boing"when starting up, with following your procedure, is it normal?

    Unless it's confirmed officially that your phone is defective, then you can ask for a replacement. Or you have to live with you. However you can trade it for a new one if you don't care the price drop.

  • OO4O, OCI-21560 when selecting records with XMLTYPE column

  • Find size of table with XMLTYPE column STORE AS BINARY XML

    Hi,
    I have a table with structure as:
    CREATE TABLE XML_TABLE_1
    ID NUMBER NOT NULL,
    SOURCE VARCHAR2(255 CHAR) NOT NULL,
    XML_TEXT SYS.XMLTYPE,
    CREATION_DATE TIMESTAMP(6) NOT NULL
    XMLTYPE XML_TEXT STORE AS BINARY XML (
    TABLESPACE Tablespace1_LOB
    DISABLE STORAGE IN ROW
    CHUNK 16384
    RETENTION
    CACHE READS
    NOLOGGING)
    ALLOW NONSCHEMA
    DISALLOW ANYSCHEMA
    TABLESPACE Tablespace2_DATA
    - So HOW do I find the total size occupied by this table. Does BINARY storage work as LOB storage. i.e. I need to consider USER_LOBS as well for this.
    OR foll. will work
    select segment_name as tablename, sum(bytes/ (1024 * 1024 * 1024 )) as tablesize_in_GB
    From dba_segments
    where segment_name = 'XML_TABLE_1'
    and OWNER = 'SCHEMANAME'
    group by segment_name ;
    - Also if I am copying it to another table of same structure as:
    Insert /*+ append */ into XML_TABLE_2 Select * from XML_TABLE_1.
    Then how much space in ROllbackSegment do I need. Is it equal to the size of the table XML_TABLE_1?
    Thanks..

    I think foll query calculates it right while including the LOB storage as:
    SELECT SUM(bytes)/1024/1024/1024 gb
    FROM dba_segments
    WHERE (owner = 'SCHEMA_NAME' and
    segment_name = 'TABLE_NAME')
    OR (owner, segment_name) IN (
    SELECT owner, segment_name
    FROM dba_lobs
    WHERE owner = 'SCHEMA_NAME'
    AND table_name = 'TABLE_NAME')
    It's 80 GB for our Table with XMLType Column.
    But for the second point:
    Do we need 80GB of UNDO/ROLLBACK Segment for performing:
    Insert /*+ append */ into TableName1 Select * from TableName;
    Thanks..

  • Ftp.belnet.be mirror very slow with updates

    The mirror that is closest to my location, ftp.belnet.be , seems to be very slow with updates for AL.
    XFCE4 was updated to 4.2.3 around nov 10 on archlinux.org.
    11 days later xfce4 4.2.2 is still on belnet , and not replaced by the new version.
    Since it's also a fast and reliable server, i don't mind waiting a few days, but more than a week is TOO long.
    What's the use of a bleeding edge distribution when you can't get updates that have been available for more than a week ?
    For now, i have fallen back on archlinux.org , but will look for another european server.

    In contrast with the name, that server doesn't seem to have ANY arch packages anymore.

  • TC VERY SLOW with backup

    Suddenly, TC is VERY SLOW with backup. In fact, I went in and discovered that it had not completed a backup since July 19th. I started one last night and when I checked this morning (about 10 hours later) it was 70MB into a 2GB backup. An hour and a half later it was at 100MB and an hour after that it was at 125MB. At this rate, it's going to take a couple of days so I cancelled the backup (it then went into it's housekeeping routine of "cleaning up"). BTW, I had quit all applications before I started the backup and TC said I had 454GB of free space. I'm not running any AV software and I have OS 10.6.8 I'm on an Ethernet network to the TC (I also have Airport active - could that be an issue? It never was in the past)
    Any ideas would be appreciated.

    So...I may have panicked when I saw all of those empty folders in my Document folder...however, when stopping the backup to TC (the 'cleaning up' process of stopping took more than 2 hours), my folder contents showed up. I guess that process takes the file index pointers offline or something so I couldn't see file contents during the process. I then did a permissions repair and a verify on my hard drive.
    But the bad news is that my Time Machine is still showing EMPTY! I currently running disc utility 'verify' on my TM backup volume (it says the projected time to complete is 3 days!!!) The disc utility says that there are 4,000,000 files in the backup volume - I just can't see them. When I ran Time Machine, it only has 'today' - no prior backups - even though Time Machine Preferences reports that the oldest backup is August 1, 2010 (one year ago) and that the last backup was July 19, 2011. They are not there.
    I've seen some other posts like this, so I don't think I'm alone with this problem.
    The good news is that all of my folders and files on my computer appear to be intact. The bad news is that previous Time Machine backups are not there (or they can't be seen - even though the 1TB backup volume is in fact half full).

    One possible solution would be to organise your inbox into folders.
    Its never relly good on any system to have one folder that has everything in it.
    Try going to you web gui for that mail account and organise your folders and move mails from your inbox into corresponding folders for better organisation.
    Several folders containing the same amount of one folder will usually load a little quicker as the folder may not be accessed to download its content unless veiwed.
    So having 10 folders with organised content, and you inbox as an area thats to hold only new emails would work much much quicker with imap.
    Most imap servers will only update the contents of a folder when its veiwed.

Maybe you are looking for
