• Help with the query to select only one record from the result set in double

  Hello

  Please help with the query. Version of Oracle database we use is 10g R2.

  I have a vision that is duplicated IDS, but they are used across the different functions. See below examples of data. Please help me with a query to select only one record (based on ID regardless of the area) from the bottom of the result set of duplicate records. For what is the point of view is there unique records, given the combination of the fields ID, Org, DF, dry, Sub-Sec

  ID	Org	DF	Sec	Sub-Sec

  
  (163)CQCPDMCPDMHD(163)PCENGENGENG(163)CQASICASICIS8888TSTACTACTAC(163)TSHEHESW6789CQINFOINFOFOS6789PCSECSYSSECSYSINFO16789TSSECSYSSECSYSINFO29009PCBMSBMSBMS1

  My result set must eliminate the duplicate identifiers regardless of whoever we choose of the result set. (I mean without distinction Org, DF, s, Sub-s). My expected result set should be.

  ID	DSB

  
  DF
  SEC
  Sub-Sec
  (163)CQCPDMCPDMHD8888TSTACTACTAC6789CQINFOINFOFOS9009PCBMSBMSBMS1

  Hello

  This sounds like a job for ROW_NUMBER:

  WITH got_r_num AS

  (

  SELECT id, DSB, df, s, sub_sec org

  ROW_NUMBER () OVER (PARTITION BY ID.

  ORDER BY org

  ) AS r_num

  OF view_x

  )

  SELECT id, DSB, df, sub_sec s,

  OF got_r_num

  WHERE r_num = 1

  ;

  He is a Top - N query example, where you choose the elements of N (N = 1 in this case) from the top of an ordered list.

  I hope that answers your question.
  If not, post a small example of data (CREATE TABLE and INSERT, only relevant columns instructions) to your sample data and the results desired from these data.  (I know that you said that you were a view selection.  Just for this thread, pretending it is a picture and post simple CREATE TABLE and INSERT statements to simulate your point of view).
  Point where the above query is to produce erroneous results, and explain, using specific examples, how you get the right results from data provided in these places.  (I didn't quite understand the explanation above.  I don't know why you want to

  ID ORG DF DRY SUB_SEC

  and is not

  1234 IS CQ ASIC, ASIC

  or

  If you change the query at all, post your modified version.
  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

• Need help with the data storage store, local array and network connections

  Need help with my ESXi 4.1 installation

  My hardware:

  I built a server with an Asus P6T whitebox, i7 920, 12 Gig RAM, NIC, Intel Pro1000 PT Quad, 3ware 9650SE-12ML with 8 1.5 TB SATA green in a raid 6 array gives me about 8 + TB with a spare drive all housed within a NORCO RPC-4220 4U Rackmount Server chassis.  I also have a 500 GB SATA drive which will hold the ESXi and virtual machines.

  The network includes a firewall, Netgear Prosafe FVS336G, GS724Tv of Netgear ProSafe 24 port Gigabit Managed Switch on a dhcp cable modem internet service provider.

  I also have 2 old NetGear SC101T NAS disks (4to) I want to connect to the system how some - at a later date have... data on them and want to transfer to the new storage array. I always looking into the question of whether they will work with ESXi 4.1, or I might have to only access it through Windows XP.

  My Situation:

  I have already installed ESXi 4.1 and vsphere client with no problems and it is connected to a dhcp cable internet service.  I've set up host via a dynamic DNS service name give me a static hostname on the internet.  I installed three machines to virtual OS successfully at the moment and now want to first start by creating a multimedia storage server which will use some of this new 8 TB array, then separate data storage for use with a web server small overhead storage and a backup.  It is a domestic installation.

  Help with the data store and network:

  I was doing some reading, because I'm new to this, and it looks like I'll probably want to set up my table via ESXi as a nfs disk format.  Now, the data store is usually in another physical box from what I understand, but I put my readers and ESXi all in the same box.  I'm not sure that the best way to put in place with grouped network cards, but I want to make this work.

  I understand that in ESXi 4.1 using iSCSi LUN must be less than 2 TB, but nfs - I should be able to add a bigger partition then 2 TB (for my multimedia) in nfs, right? or should I still add it separately as a separate 2 TB drives and then extend them to get the biggest space.

  Any suggestions or direct resources showing examples on how to actually add some parts of the table as data warehouses separate nfs.  I know that to go to the configuration tab, and then select Add to storage, and then select nfs. I have not my picture, but it's here that I don't know what to do because ESXi 4.1 system already has an address, should I put the same thing to the new data store array also (will it work?), and what should I use for the name of the folder and the store of data... just do something to the top.  I thought to later install Openfiler (for a multimedia storage using this table server) as a virtual machine, use the table with esxi so that I can access the same storage space with widows and linux-based systems.

  I also know I have to find a way to better use my quad nic card... put in place of virtual switches, grouping, etc HELP?

  Any direction, assistance, similar facilities to sample, suggestions or resources that would help would be great. I did a lot of hunting, but still a little confused on how to best to put in place.

  You must think of VMDK files of large databases with records of random size guest go read some data (a DLL or an INI file), maybe write some data back, then go read other data. Some files are tiny, but certain DLLs are several megabytes. It's random i/o all and heavy on the search time. IO Opsys is small random operations that are often sequential (go read data, write data, go read other data,...) so that deadlines are critical to the overall performance. That's why people say OPS are / s of reference and forget the MBs flow. The only time where you bulk transfers are when you read media (ISO files).

  Well, now forget all this. Actually the disk activity will depend on the specific applications (database? mail server? machines compiler?), but the above is true for boots, and whenever applications are idle. You should see the profile to know.

  RAID 10 is faster (and often more reliable) than RAID 5 or RAID-6 except in certain specific cases. In General RAID 10 is ideal for many random writes, since the calculation of parity for RAID-5 and - 6 adds to the overall latency between command and response - latency is cumulative if a little slow here and a little slow it adds up to a lot of overall slow synchronous especially with e/s on a network. OTOH RAID-5 and -6 can produce faster readings due to the number of heads, so you can use it for virtual machines that transfer bulk. Test. You may find that you need several different types subdashboards for best results.

  You said 3ware, they have some good grades on their site, but don't believe it. With my 9650 that I found myself with only a couple of their recommendations-, I put the (simple) table for allocation size 256 k, nr_requests at 2 x the queue_depth and use the planner date limit. I had the habit for the Ext4 file system formatted with stride and stripe-width synced to the table and used the options large_files with fewer inodes (do not use the huge_files option unless you plan to have single VMDK files in the terabyte range). Use a cache of great reading in advance.

  Virtual machines use VMDK files in all cases except raw iSCSI LUN that they treat native disks. VMDK is easier to manage - you can make a backup by copying the file, you can move it to a PC and load it into another flavour of VMware, etc. There could be some features iSCSI to your San as a transparent migration but nothing for me. NFS has less chatter of Protocol if latency lower times to complete an operation. NFS is good to read and write a block of data, that's all it boils down to.

  UPS is good, but it won't help if something inside the machine explodes (UPS does nothing if the PC power supply goes down). If the RAID card has an option for a battery backup module, so it can contain some writings in memory and may end up the disk i/o after replacing the power supply. 3ware also limits the types of caching available if help is not installed, and you get just the right numbers with the module.

• trigger for update field in a table with the sum of the fields to another table

  My experience in creation of triggers and pl/sql in general can be described in terms of oracle with the null value. I practiced by creating arrays and applications on my personal server at home to help me with some of my work related tasks. Right now I am creating a trigger which will, after insert, update, delete on the update of the table assignment_time_track the area of the time_spent on the table of assignments with the sum of the time_spent on the assignment_time_track table fields. I hope that run on the sentence it is clear to the people other than me. I tried this script on my own using the tool of creation of trigger for Oracle Database Express Edition, but I get the following error:
  
  Create a trigger failed, for the following reason:
  ORA-06552: PL/SQL: ORA-06553 finished Compilation unit analysis: PLS-320: the declaration of the type of the expression is incomplete or incorrect
  
  Here is my attempt to create the trigger on my own.
  
  create or replace trigger "ASSIGNMENT_TIME_TRACK_T1".
  AFTER
  INSERT or update or delete on 'ASSIGNMENT_TIME_TRACK '.
  for each line
  Start
  update assignments
  Set time_spent = (select sum (time_spent)
  of assignment_time_track
  where assignment_time_track.name = assignments.name);
  
  end;
  /
  
  
  If what I posted is not clear or more detail is needed, let me know and I will respond with a full description of tables and my goals for each table. Thanks in advance for any help. I also gladly accepts links to tutorials or lessons that explain how to do this kind of thing.

  I think I understand what you mean :)

  Rather than use a trigger to keep the master table (assignments) in sync with the time spent on the details, it would be much easier to use a query to do this, maybe creating a view.

  Something along the lines of

  SQL> create table assignments
    2  (id number primary key
    3  ,name varchar2(10)
    4  );
  
  Table created.
  
  SQL>
  SQL> create table assignment_time_tbl
    2  (id number primary key
    3  ,assid number references assignments
    4  ,time_spent number
    5  );
  
  Table created.
  
  SQL>
  SQL> insert into assignments
    2  select rownum
    3       , 'a'
    4    from all_objects
    5   where rownum < 5
    6  /

  Hello

  The link below is a guige to install a video card in your Pc.  In particular, it seems that you will have to perhaps specify the location of the new card in the bios and save this change before you install the new card - see step 4 in the guide on the link below.  If your new card fits into the PCI Express x 16 slot, you will need to define PCI Express in the bios and save the changes.
