• How it warns Oracle to use an index for the join of two tables...

  How to prevent the Oracle to use an index for the join of two tables to get a view online that is used in an update statement?
  
  O.K. I think I should explain what I mean:
  
  When you join two tables that have many entries sometimes there're better is not to use an index on the column that is used as a criterion to join.
  
  I have two tables: table A and table B.
  
  Table A has 4,000,000 entries and table B has 700,000 entries.
  
  I have a join of two tables with a numeric column as join criteria.
  
  There is an index on this column in A table.
  
  So I instead of
  

    where (A.col = B.col)

  I want to use
  

    where (A.col+0 = B.col)

  in order to avoid Oracle using the index.
  
  When I use the join in a select query, it works.
  
  But when I use the join as inline in an update statement I get the error ORA-01779.
  
  When I remove the '+ 0' the update statement works. (The column is unique in table B).
  
  Any ideas why this happens?
  
  Thank you very much in advance for any help.

• Satellite A60-142: Tips for the new laptop

  Hi all

  I think to buy a new laptop.
  I currently have a Satellite A60-142 and I only am not too thrilled about this model since the fan makes me crazy... It is constantly running and compared to my old laptop (Satellite 1410-304), it makes a lot of noise...

  So, I want to get a new laptop which is quieter...
  I need basically for email/surfing/Online games/digital still camera.

  Thanks for the tips!
  Ellen

  Hi Ellen

  Well, it is a known issue that, often, the fan works. If you play games or use other applications, the laptop works at high performance and the parts of the device as the processor or graphics card produce a lot of heat. In this case, aeration run also at high speed. It is a simple fact.
  As far as I know, you can try to change the settings of cooling in the power utility.
  In addition it is not easy to say which model of laptop runs more quiet. In the notebooks of high performance fans are bigger and louder by contrast office books are ineffective but easier to cool.

  It's not easy to make a choice

  Good bye

• Tips for the replacement of DVD burners on Tecra series

  I think I need to replace my DVD burner. I used a carpet * a UJ-811 t came with the laptop, but it is no longer Burns correctly, although he continues to play well. Initially, I thought it was a problem with Nero (calibration error), but it doesn't matter what burning program I use. I spent a weekend through various forums looking for a solution: I ran a lens clean and updated drivers, looked for the firmware updates (nobody seems to be able to find for the carpet *, including on the Firmware Page), tried the brands of different media (although I initially using Sony and TDK in any case). All with no luck. So I think that he has reached the stage that I need to replace the burner itself.

  So, advice on brands and type? I want something that is internal and easy self-installation. I would like to also buy online and get fast shipping (I'm leaving Ireland in about a month) so also website suggestions welcome. Please keep your relatively simple tips; I am a relative novice who learns quickly.

  Thanks in advance.

  Hello

  It's a shame! It of always frustrating when the player no longer works!
  But there is not much to do! You said that the calibration error message appears.
  Well, it seems that the drive cannot calibrate the lens correctly and this leads to problems of engraving!
  As you already assumed the replacement drive is required!

  Usually, the user that was preinstalled on your laptop manual should provide some compatible readers and supported!
  Check it! My user manual contains this info!

  But if you don t find anything, I recommend you contact the ASP in your country for the disk drive!
  You should know that not all readers are compatible because of the master/slave/c-salt settings.
  If the drive supports bad settings of the BIOS does not correctly recognize this device!

  So, make a call to the service provider and ask for more details! Good luck

• Tips for the TCP wait of asynchronous Messages with non-standard expression tanks

  Hi all

  I have a PITA instrument that I need to communicate with in a system of greater control.  This instrument communicates via RS232 to a server running on the PC OEM application.  In order to communicate with the instrument, I have to use the TCP protocol on a specific port on Localhost - So far so good as long the protcol is answer command.

  The problem is that the instrument sends several messages asynchronously of different sizes with a double newline as a tank of termination (there are many CR/LFS all these messages so that they cannot be a MOE) and I am struggling to find a way to manage receive asynchronous messages of variable length with a cusom CHARACTER term. without having simply a fast dedicated for TCP loop reads trying to catch these asynchronous status messages.

  I wish the functions VISA TCP has worked with the local host, given that the properties that can be set to change the chariot of non-standard term.

  Open to suggestions-

  Thank you

  Ronin

  Yes, I'll be streaming in my own string buffer and then to choose the messages out of the buffer when you find the stop character.

  A technique to improve performance, rather than reading a single byte at a time is to use the "immediate" on reading TCP mode and use a high value for the "bytes read" - in this way, it will return all of the data that is there without waiting for all the specified bytes or the time-out. He will wait only the full timeout if 0 bytes are received (which you can ignore) - set to a low value such as 100ms.

• JOINT-2: Tips for the initial configuration of the network?

  Hello team:

  I was asked to do a very basic configuration of a whole new JOINT-2 on a CAT6500. According to the documentation, once in the Supervisor´s CLI, I run a 'session' command to the location where the METHOD.

  Once, I follow the wizard to add the IP, mask and gateway. Having this configured, the management interface of module´s should be visible from the rest of the network, but I do not see how this happens, because the module must use one of VLAN switch´s and I haven´t found how it is configured.

  Question: how will this link JOINT itself for layer 3 engine switch´s? I don't see how its layer 2 will correspond to any VLAN available in the host LAN switch...

  Any help will be greatly appreciated

  I think what you need to add a command on the 6500 that puts management of JOINT-2 port in a vlan individual.  For example:

  intrusion detection module 9 management access port - vlan 101

  This places the management for the joint-2 card port 9 slot vlan 101.  The host IP that you set on the map of JOINT-2 itself then be valid for that vlan.

• transformation script changes not saved in design

  Hello

  I made several scripts processing to change my relational model to the Data Modeler.

  One of the scripts defined abbreviations of table for all the table based on the PK constraint. (I'm importing the model of my data dictionary which has PK constraints defined as {abbr} _PK)

  After I "Apply of Scripts of Transformation Custom", I see that all tables have now an abbreviation of the table.

  However, if I save my design, close and reopen it, all abbreviations are empty again.

  I did a few tests and manually fill the field of abbreviation Table changes be saved.

  If I check the table XML files, I can clearly see that the table for which I manually added the acronym has a < short > tag, which is not what I filled auto with the transfer script.

  I noticed a similar behavior for scripts that I use to fill the parameters of Auto_inrement and others. After I run the script, I can see all the values filled in my template, but is not be saved and I lose all the changes made after closing my model.

  I noticed that the changes be saved if I choose Save as and save my template in a new directory (however to register as in the same directory create a SVN error).

  Is there something I should add to my .js script that changes be saved?

  Is this a bug?

  Does anyone else have these issues?

• Please, I need a tip for my lighter becames script. I want to use a single table.

  Hello.

  
  I would like to help to help me think

  I have a list of customers with their information (phone, address, email, name,...). There are about 120 customers.

  So I put a drop-down list where there are all the clients/names. When the user choose a name, it will change (on the same page, below the drop-down list object down) the selected customer information (e-mail, address, telephone, etc.).

  
  I had to do so using more than one table with the same name of the value selected in the drop down. For example: If the user selects a name with the same name of a table, this table will be your presence changed to visible. It works perfectly, but my form (in Design view) became slow much (why there are a lot of breast in a unique subform table).

  
  Can someone tells me if there is another way to do it using a simple and lightweight way

  NOTE: I use table, because in every piece of information, for example phone, I put a phone icon/image and also to keep all the information in one place.

  Is there an example here.

  

  If you look at the ScriptObject, I placed 4 information of different customers.

  When adding values to the drop-down list, I'm only using the Name value...

  At runtime, when the user selects one of the customer name in the drop-down list, then I need to pick up all the related information for the customer selected from the code of script object. To do this, I'm looping through all cstomers in the Script object and comparing the name value to find out whose name has been chosen.

  Once the code identifies the name is selected, then related information will fill in the other fields.

  I hope this helps...

  Thank you

• NodePropValue for the associated nodes

  Hello world

  How to use the function nodepropvalue to the associated nodes property? For example: I have a property "associated node" (ballasts call this Custom.AN) for a sheet and this property has several nodes mapped to another hierarchy. Property Custom.AN indicates the name of the nodes in the other hierarchy (separated by commas), but I want the description associated with the mapped node (lets call this Custom.Alias). The formula below that doesn't seem to work, I wrote:

  NodePropValue (PropValue (Custom.AN), Custom.Alias)

  Using only PropValue (Custom.AN) returns:

  Prefix_NODE1, Prefix_Node2, Prefix_Node3, Prefix_Node 4...

  I want to get the final formula (what I was hoping would give me nodepropvalue) result:

  descr1, descr2, descr3...

  so for each sheet, I have these and then I can this hub to my export table.

  Thank you

  Sumit

  Hi Sumit,

  Try to create two accessories

  Prop1-HierNodePropValue (the HierarchyName, Abbrev (), Custom.Alias)

• Parent index for the data in a table?

  Is there a way to index a child table with a function to include a column from a parent table?

  Example:

  I want to see how many children live in a zip code (and their address is listed with their parents)

  Select count (*)

  class c of child, parent p

  where c.parent_id = p.parent_id

  and p.zipcode = "12345"

  Is there a way to make an index of children with a function that gets parents zip code?

  Thanks for the help?

  An index on the child table can reference only the columns of the child table.  You can't have an index on the child table that is based on information from the parent table.

  There are the function-based index, but they may involve only constants and deterministic functions (and, of course, the columns of the table).  For example, the child table could have a clue on UPPER (name), where last_name is a column of the table, but he could not have a clue about get_zip (parent_id), where get_zip is a function defined by the user who queries the parent table.

  Well - you "might" have a functional indication if you did to be deterministic, but it is not recommended because if the changed zip_code parent would really not deterministic and the change would not be included in the index.

  This apart from this code will work properly if the zip_code data does not change:

  CREATE TABLE parent (COL1 number primary key, zip VARCHAR2 (5))
      
  create the child table (col1 number, parent_key number);

  create or replace function get_zip (number p_key) return deterministic varchar2 as
  v_zip varchar2 (5);
  Start
  Select zip from v_zip of the parent where col1 = p_key;
  Return v_zip;
  end;

  /

  create indexes on children (get_zip (parent_key)) child_zip;

• Casting table PL/SQL for the type of existing table and back ref cursor

  Hello
  
  
  
  I have the problem of casting a pl/sql table for the type of an existing table and turning the ref cursor to the application. Casting a ref cursor back and number of pl/sql table works well.
  
  
  
  Declarant
  
  < strong > TYPE type_table_name IS TABLE OF THE package_name.table_name%ROWTYPE; < facilities >
  
  within the stored procedure, fill in a table of this type temp_table_name and returning the ref cursor help
  
  < strong > results OPEN to SELECT * FROM TABLE (CAST (temp_table_name AS type_table_name)); < facilities >
  
  generates an error. type_table_name is unknown in this distribution. According to me, this happens because of the declaration of the type locally.
  
  
  
  Statement type_table_name inside the package specification does not work neither. Incredible, cast to the said dbms_sql.number_table to specify ref cursor back and dbms_sql package works very well!
  
  
  
  < strong > CREATE TYPE type_table_name IS TABLE OF THE package_name.table_name%ROWTYPE; < facilities > deals without any error but creates an invalid type complain a reference to package_name.table_name
  
  
  
  I don't want to declare every column in the table in type_table_name, because any change the table_name table would result in an inconsistent type_table_name.
  
  
  
  Thanks in advance!
  
  Edited by: user6014545 the 20.10.2008 01:04

  In any case you are right that there is a problem around anchorage (or maintaining) types of objects persistent to match the table structures, they may represent.

  In the case you describe, you might be better off just open the refcursor immediately the using one of the techniques described in the http://www.williamrobertson.net/documents/comma-separated.html to manage the delimited list.

  In the more general case where the line of treatment is necessary, you may make the pipeline functions.

• How to connect a scanner of network including the Windows 7 firewall is blocking and adding an exception for the associated program to access the scanned files has no effect?

  Hello

  I have recently upgraded to Windows 7 and the process for adding some of my old material has been an interesting question. Who made me stuck is to be able to access my network scanners "mailboxes shared" in order to recover my scans.

  The product in question is a large format Xerox 6204 printer/scanner. The installation process for the basic print server run the 6204 as a network printer went relatively smoothly and seems to work as expected. However, the problem arises when I want to use the functionality of scan of the 6204. Scans are stored in mailbox store ' ' on the 6204 and must be retrieved by a piece of software Xerox called "wide Format Scan Service. This program essentially connects to mailboxes mailbox via the IP address of the 6204 on the network and from there should allow me to download the scans on my Windows 7 computer. Unfortunately, in order to connect to the mailbox store I am currently disable the firewall of Windows 7 altogether.

  I tried to add the Service to Scan large Format to the list of allowed programs, which gives an "impossible to connect to 6204' error. I tried to add the program to inbound and outbound rules manually, even though my experience with this is limited, with the same error. So leave the default settings in the wizard, I also tried to use the technical netstat to find out what are the ports, the software used and adding them to specific ports in the properties of the rules - all without success.

  For now, I'm stuck the point of having to run my installation of Windows 7 without a firewall to use my scanner large format, which is obviously an undesirable situation. If anyone can offer help or advice on how I can solve this problem it would be greatly appreciated.

  Try this... This solves the problem

  netsh advfirewall set global disable StatefulFTP
