• Creating a unique index frame on a one-to-many table and search

  Hello
  
  I was properly put in place of the full text index on multiple columns on the same table (using the MULTI_COLUMN_DATASTORE preferences), but now I have a situation with a table of one-to-many data collection (with a CF of a lookup table), and I need to get columns through two of these tables. Code example below, several of my chatter after the code block:
  

  CREATE TABLE SUBMISSION
  ( SUBMISSION_ID             NUMBER(10)          NOT NULL,
    SUBMISSION_NAME           VARCHAR2(100)       NOT NULL
  );
   
  CREATE TABLE ADVISOR_TYPE
  ( ADVISOR_TYPE_ID           NUMBER(10)          NOT NULL,
    ADVISOR_TYPE_NAME         VARCHAR2(50)        NOT NULL
  );
    
  CREATE TABLE SUBMISSION_ADVISORS
  ( SUBMISSION_ADVISORS_ID    NUMBER(10)          NOT NULL,
    SUBMISSION_ID             NUMBER(10)          NOT NULL,
    ADVISOR_TYPE_ID           NUMBER(10)          NOT NULL,
    FIRST_NAME                VARCHAR(50)         NULL,
    LAST_NAME                 VARCHAR(50)         NULL,
    SUFFIX                    VARCHAR(20)         NULL
  );
  
  INSERT INTO SUBMISSION (SUBMISSION_ID, SUBMISSION_NAME) VALUES (1, 'Some Research Paper');
  INSERT INTO SUBMISSION (SUBMISSION_ID, SUBMISSION_NAME) VALUES (2, 'Thesis on 17th Century Weather Patterns');
  INSERT INTO SUBMISSION (SUBMISSION_ID, SUBMISSION_NAME) VALUES (3, 'Statistical Analysis on Sunny Days in March');
  
  INSERT INTO ADVISOR_TYPE (ADVISOR_TYPE_ID, ADVISOR_TYPE_NAME) VALUES (1, 'Department Chair');
  INSERT INTO ADVISOR_TYPE (ADVISOR_TYPE_ID, ADVISOR_TYPE_NAME) VALUES (2, 'Department Co-Chair');
  INSERT INTO ADVISOR_TYPE (ADVISOR_TYPE_ID, ADVISOR_TYPE_NAME) VALUES (3, 'Professor');
  INSERT INTO ADVISOR_TYPE (ADVISOR_TYPE_ID, ADVISOR_TYPE_NAME) VALUES (4, 'Associate Professor');
  INSERT INTO ADVISOR_TYPE (ADVISOR_TYPE_ID, ADVISOR_TYPE_NAME) VALUES (5, 'Scientist');
  
  INSERT INTO SUBMISSION_ADVISORS (SUBMISSION_ADVISORS_ID, SUBMISSION_ID, ADVISOR_TYPE_ID, FIRST_NAME, LAST_NAME, SUFFIX) VALUES (1,1,2,'John', 'Doe', 'PhD');
  INSERT INTO SUBMISSION_ADVISORS (SUBMISSION_ADVISORS_ID, SUBMISSION_ID, ADVISOR_TYPE_ID, FIRST_NAME, LAST_NAME, SUFFIX) VALUES (2,1,2,'Jane', 'Doe', 'PhD');
  INSERT INTO SUBMISSION_ADVISORS (SUBMISSION_ADVISORS_ID, SUBMISSION_ID, ADVISOR_TYPE_ID, FIRST_NAME, LAST_NAME, SUFFIX) VALUES (3,2,3,'Johan', 'Smith', NULL);
  INSERT INTO SUBMISSION_ADVISORS (SUBMISSION_ADVISORS_ID, SUBMISSION_ID, ADVISOR_TYPE_ID, FIRST_NAME, LAST_NAME, SUFFIX) VALUES (4,2,4,'Magnus', 'Jackson', 'MS');
  INSERT INTO SUBMISSION_ADVISORS (SUBMISSION_ADVISORS_ID, SUBMISSION_ID, ADVISOR_TYPE_ID, FIRST_NAME, LAST_NAME, SUFFIX) VALUES (5,3,5,'Williard', 'Forsberg', 'AMS');
   
  COMMIT;

  I want to be able to create a text index to group these fields:
  
  SUBMISSION_ADVISORS. FIRST NAME
  SUBMISSION_ADVISORS. LAST_NAME
  SUBMISSION_ADVISORS. SUFFIX
  ADVISOR_TYPE. ADVISOR_TYPE_NAME
  
  I looked at DETAIL_DATASTORE and USER_DATASTORE, but examples of Oracle Docs for DETAIL_DATASTORE leave me a little confused. It seems that this should be fairly simple.
  
  Ideally, I try to avoid creating new columns and keeping a minimum shutter adjustments. But I'm open to any suggestion. Thanks for your time and your thoughts.

  I would create a procedure that creates a virtual with labels document, what is the multi_column_datatstore behind the scenes. Then I would like to use this procedure in a user_datastore, so the result is the same for several tables as a multi_column_datastore for a table. I would use auto_section_group or another type of Group of sections, so that you can search from WITHIN as with the multi_column_datastore. Please see the demo below.

  then how the data on the "authors" table columns 'author_id' and 'book_d '?
  
  don't know how to frame the table 'authors '...
  
  It would become the relation 1-1... is it normal?
  
  Please help how data will be in the "authors" table
  
  Thank you

  You do not want to have a database template that you have illustrated below. Why? Well to start tt does not pass even the first normal form. Secondly, if you had ever updated the author's name, you will need to update in several places, which could lead to problems of data integrity. A database designed to reduce redundancy, the structure that you have proposed increases it.

  If you had been modelling a one-to-many relationship, it would be more appropriate:

  CREATE TABLE authors
  ( author_id  NUMBER        PRIMARY KEY
  , last_name  VARCHAR2(200) NOT NULL
  , first_name VARCHAR2(200) NOT NULL
  );
  
  CREATE TABLE books
  ( book_id NUMBER        PRIMARY KEY
  , title   VARCHAR2(200)
  );
  
  CREATE TABLE authors_of_books
  ( author_id NUMBER NOT NULL REFERENCES authors(author_id)
  , book_id   NUMBER NOT NULL PRIMARY KEY REFERENCES books(book_id)
  );
  

  This models your one-to-many relationship with a "join" table or "bridge." The drawing above gives you the ability to change the author freely or to book the title attributes in the same place increases your data integrity.

  However, a many-to-many relationship may be more appropriate since multiple authors can write a book. So you would change the tables authors_of_books as follows:

  CREATE TABLE authors_of_books
  ( author_id NUMBER NOT NULL REFERENCES authors(author_id)
  , book_id   NUMBER NOT NULL REFERENCES books(book_id)
  , CONSTRAINT authors_of_books_pk PRIMARY KEY (author_id, book_id)
  );
  

  I hope this helps!

• Two tables that have a relationship as "many-to-many" and "one-to-many.

  I have the next two represents tables users and the other represents the items where each item can have an author (user) and of course, users can create a lot of articles, so the one-to-many relationship: -.
  
  1. users: -.
  User_id (primary_key)
  User_name
  User_sex
  user_address
  
  2.ARTICILES: -.
  Article_id
  Text
  Author_id (foreign key to the users.user_id)
  
  but the problem I have been facing is that, on another requirement each items can have several (users) approval before being published, so in this way have become the many-to-many relationship, so I created a third table called "trusts": -.
  
  3.approval: -.
  approval_id (foreign key to the users.user_id)
  article_id (foreign key to the articles.article_id)
  level.
  
  so is this a good approach to flow, or there is another way I can better build these tables.

  Hello
  Relationship seems to be ok for your current condition. but make sure you have sequence approval on your table to the approval, in case you should find the flow of approvals.

  See you soon

• One to many with several tables on one side and a table on the side "several."

  Sorry for the confusion in the title. Here's my question. In my program, I have 2 different tables that store the 2 different types of entities. Each entity has a list of attachments that I stored in a table of common attachments. There is a one-to-many relationship between the entity and the attachments table tables.
  
  () ENTITY_ONE
  ID
  NAME
  )
  
  () ENTITY_TWO
  ID
  NAME
  )
  
  ATTACHMENTS)
  ID
  ENTITY_ID
  ATTACHMENT_NAME
  )
  
  ENTITY_ID of attachments table is used to link the attachments to the one entity or two entity. All codes are generated by a single sequence. Thus, they are always unique. My question is how can I map this relationship in the EntityOne, EntityTwo and attachment JAVA class?

  For EntityOne and EntityTwo, you can simply define a normal OneToMany mapping using the foreign key.
  You use the TopLink API or APP? JPA requires a mappedBy to the OneToMany, so this may be more difficult. You should be able to simply add a JoinColumn on the OneToMany and make the Insertable/editable = false column.

  To fix, you could either map the foreign key as a Basic (DirectToFieldMapping) and maintain in force in your model or use a VariableOneToOne to TopLink mapping (this will require a common interface on behalf of entities).

• Create multiple SSID - WLC - ISE 1.4 comments

  Hello

  I wonder if there is a way to create several comments about WLC SSID with specify policy on ISE 1.4?

  I tried to create 2 comments SSID with 2 policies. The point is that it is the first policy that matches any SSID.

  Any idea?

  Concerning

  Eric

  Add airespace-wlan-id to your strategy on the ISE, ISE will use the WLAN-id to match the correct strategy

  You should talk to the school if the subscription is through them.  Probably, you won't be able to extend to yourself as a different account.

• Think about making one for the voice recording...

  I've heard great things about the new Sansa Clip +. However, I got a Sansa Express before. It was so horrible, it makes me a little skeptical on the Clip +. One of the most horrible attributes of the Express was the refresh database which came he started, taking over 7 minutes, if it didn't cut itself automatically to every time (I had to click a button to keep it close). But before all the music. For some strange reason, he would play only half of my music. Perhaps the tags have been stripped, very well. But he should be able to play without worrying, because it worked on my computer and other mp3 players.

  Sorry for snapping, but I am in desperate need of an mp3 player. I'm quite the cheap fellow; I also need a digital voice recorder voice that will work in 10-15 (never passed 20) feet. I have an old burner, but it is a consumer of battery. I can not connect to my PC.

  Now, on the mp3 player, it looks like the clip + has firmware similar to that of the Express, but cleaner and better. I saw the review and startup does not seem to be problamatic. However, I leave again I tested the voice recorder on my Express to a 15 ft. He picked up a bit of noise, but I had to max volume out to distinguish what has been recorded (which I couldn't still do).

  I really want the clip to be all around the device, I need, but he would need to work sufficiently to 15feet. I've heard so many comments, but virtually nothing about its features shortly. I really want to do, but Sansa has already failed me once...

  Hello Soy. You don't like how I answered your questions on the ABI plateau? Also, I'm very cheap, but decided to splurge on a Clip + even though I already had a rocket and a Clip. To be quite honest with you, voice recording is the function of quality lowest on the Clip + Clip and Fuze.

  I just tried to save it to my Clip + voice. I just tried two records in the sample. With the player only about 4 feet away, she picked up a lot of noise from a fan in the room. IMO to about 15 feet below the record would probably unintelligible if there is a fan noise or other noises in the room. The speech on the video recorder + works best at short distance from the speaker. Cut out from the rear of the speaker, it can make acceptable recordings.

  It is doubtful that you would get a great record with any player of mp3 of 15-20 feet away. The recorder I've mentioned, Member of the Board can be set to be very directional, but despite this, 15-20 feet away would be a mistake to get a decent record.

• Messages authenticated in the newspapers about WLC

  I have a number of controllers of WLC and I have something a little strange on one of them.  When I look at the newspaper of trapped on this one particular controller I see not all authenticated: messages.  I see DeAuthenticated: but unauthenticated:.  There are the clients associated with the APs on that controller, and when you walk in this area with a wireless device, it seems to work.  I thought it might have something to do with the record level, but these settings look the same as the rest of them.  I don't think I'll have an operational problem, but it's just kind of weird about the logging of messages.

  Thank you

  Check the trap under MANAGEMENT journal orders > SNMP > trap controls.  Under client options, "Authentication" is selected?  usually it's off default b/c, most of the people are interested in failures and no successes.  In addition, successful fill the newspapers fairly quickly.

  Thank you

• Question about WLC and Max SSID.

  Hi, I need a question:

  I had a wlc 4404 with the latest code (6.0.196.0) and many 1242ag accesspoint attached to it.

  So, what is the maximum active SSID I can publish with this equipmen?

  I think 16 but I'm not absolutely sure. If someone could confirm it?

  Connecting the access point 1142 could increase this llimitation?

  Thanks in advance.

  Good bye

• About WLC 4402 LDAP client authentication

  Hello

  I'm install a WLC 4402, the client wants to authenticate users with the LDAP and what he expected to use current users in AD, however

  I just read some documents as reference 'Local EAP authentication server on the Wireless LAN Controller with EAPFAST and LDAP
  Configuration example"and «Web authentication via LDAP on LAN Protocol wireless controllers (WLCs) example Configuration»

  Require both the then to define a new OU and define a new user and select anonymous feature of Bind.

  My question is, should I add all current on AD users on the new ORGANIZATIONAL unit in order to be authenticated as a wireless client?

  I hope that someone of you can clear my doubt

  Kind regards

  Note that LDAP with AD requires no methods EAP-mschapv2. If you can't do PEAP-mschapv2 with AD as LDAP backend. EAP-FAST EAP-FAST (GTC) and no EAP-FAST (mschapv2). It is a limitation due to the way in which AD works in LDAP mode.

  The anonymous bind is not required at all, that it is to be like this in the example. Usually, anonymous bind is not allowed by default on the current version of windows server.

  You are not forced to push all the users in an OU. Simply give a search base DN to the WLC where the WLC can reach all customers on AD. If all your users organizational units are at the root of your domain, you will need to give "DC = domain, DC = com" as base DN and it means that each search will arrive on your entire ad, which isn't super effective. That's all.

• Only one link, many cases?

  I'm new to InDesign but experienced with Illustrator. I use CS5.5.

  I've got work in Illustrator for a set of 6 icons. I want to import files 6 icon (Illustrator format) in InDesign, and then copy and paste icons several times into the cells of a table I created. My first attempt at this led links of 292 display panel (divided between the 6 icons). I don't think I'm doing this right. Should the links Panel show just 6 links (one for each imported Illustrator artwork file) and I copy and paste an "instance" of this link? This would be akin to Illustrator where you can convert work in a 'symbol' and whenever you copy and paste that you are dealing with a symbol 'instance' rather than a duplicate of the real work (reducing the size of the file).

  That's how it should work, but you can see the file several times it's only once in memory of InDesigns.

  Since CS5 however you have been able to change how they are displayed, see the circle arrow in this picture:

  

  You can click on that to narrow the list down to one line, and it will show how many instances of the link there is between parentheses.   If you want to replace the link click on the top line and recreate a link and you are going to do all instances at once, or click an individual instance to replace than this one.
