• Basic concept of loop PID closed

  Hello

  I have a problem of very basic concept of PID loop closed. I read a lot of material of the PID controller but still confused.

  I understand that the error between the measure and the desired will be processed by PID controller, but I do not understand how the controller output (sum of three P/I/D) set the right plant behand the controller. For example, an electric motor fan will be below on a Board, the force of the wind on the motherboard could be detected by the tension and of course the fan speed could be adjusted by tension. But the error of the setpoint and the process variable will go directly to the fan in Labview without identifying the mechanisms on the plant (fan). I wonder if anyone knows how this error is treated by the plant. And why we need not care about the transfer of the factory function.

  If you have a transfer function for your plants, you don't need PID, because the output of the optimal control can be determined directly from the transfer function! (Well, more specifically, often in this case you would use the transfer to feed-forward control function, which you would combine with PID to correct minor variations between the reality and transfer function model.)

  The output of PID is not a sum of errors. It is a sum of the outputs of regulation - the proportional output, the full output and the derived products output. The gains set the regulator to the specific system, and if they are not chosen correctly, the control will be terrible and potentially unstable.

  In your hypothetical example of two systems - Yes, it is quite possible that one moment the error and so the output will be the same. But if the systems are very different, the next iteration of control errors will be different, so the next controller output value will be different, etc. And if the systems are very different, they should not have the same gains.

• basic concepts

  I was using java with JCOP of 3-4 months, but I do have a few basic concepts. PS please can someone explain me the steps of initialling a java card. I mean that, as when a computer starts, it has some steps, then what are the steps of java card? How is to be initialization by the JCOP, and what is the concept of the keys that are stored by the JCOP in java card?

  The best thing to do, it is write code! More, you can implement the best from scratch. Try implementing a secured on a card (ISO7816) e-mail system. Develop code chaining from scratch.

• 10G Confirmation of Passes the necessary review for OCA and OCP

  Hello
  
  My apologies if this was asked in another thread.
  
  In order to be allowed to win 10 G OCP I must pass these exams in the following order:
  
  1Z0 - 042 and one of these (1Z0-007, 1Z0-047, 1Z0 - 051) to win the OCA first, then 1Z0-043(plus course).
  
  I passed 1Z0-042 and I was keen to study for 1Z0 - 043 then. I learned that before I can sit 1Z0 - 043, I would need to fill out one of these first (1Z0-007, 1Z0-051 and 1Z0-047).
  
  Please confirm the right course of action for me.
  
  Thank you

  Thank you

  You can take the exams in any order you like. So, if you want to 1z0-043 then (1z0-007/047/051) as you seem to want to do you can.

  If you seem to have been said misinformation... however...

  0) If you have passed 1z0-042 long, dec 2008 memory, you don't have to do a review of SQL. Certview will show your exemption if you are exempt. And you will already be a DBA OCA 10 g.
  (1) it is IMHO probably far much more sense do 1z0-051 and 1z0 - 007 before continuing with 1z0-043.
  -It's because passing a SQL you will win (with you pass 1z0-042) a DBA OCA 10 g. ... and also because good SQL will help with your practice of the Oracle and your study of OCP.
  ---(Une exception pourrait être si yu juste assisté à une mains sur parcours et souhaite étudier pour tirer de l'examen 1z0-043 dès que possible après le cours).

  Thinking is important for you to have planned to participate in a hand that is appropriate on the course for your 10g OCP DBA... his time thinking that if your haven't already.

• Next review after 'Introduction to SQL Oracle9i (1Z0-007)'?

  Hello

  I finished IZ0 - 007 before 2 years please let me know what is the next review so that I can go. I have 6 years epx in SQL/PL SQL.

  Based on your statement "I'm 6 years old epx in SQL/PL SQL.. -My first inclination would be to suggest 1Z0-144: Oracle Database 11 g: program PL/SQL.  This is the standard test for PL/SQL developers to start and this (in conjunction with your score 1Z0-007) will save the Oracle PL/SQL Developer Certified Associate credentials. 1Z0-047 is an older version of the review of PL/SQL.  I recommend usually 1Z0-144 on 1Z0 - 147:

  Oracle PL/SQL Developer Certification: 1Z0-147 or 1Z0-144?

  If you pass the exam 1Z0-144, you could consider further 1Z0-146: Oracle Database 11g: Advanced PL/SQL. Pass this test after the OCA will make you an Advanced Oracle PL/SQL Developer Certified Professional.

  You can find links to study materials for the two reviews to the URL below:

• Basic concepts of Replay/AA

  Hi all

  As the title says, I have a difficult time in my head around a few basics of packaging. I looked for a guide of the user to Replay 4.7, but they apparently were fired. I have read a few KB and release notes, but they are not helping.

  (1) where I can d/l a guide to 4.7?

  (2) for the choice of a just restore point choose the most recent time regardless of the size and if so how does it work? During the day on a 1.5 to is a snapshot of server files maybe 600 GB and another 4 hours later is 20 GB. How could a snapshot of 20 GB (more the base image I suppose) give me a full 1.5 TB of data recovery?

  (3) make other people experience extremely slow LAN speed of transfer for the large restorations? I'm talking about 48 hours or more? VM side, how ever would that be useful? What can I do to speed up the process?

  Thanks in advance.

  Hi Corrigun:

  You can find some Replay 4 docs on the link below. I suspect that the backup Admin Guide is what might meet your needs. However, the other docs can help by giving you a better picture about the features of this product.

• I have a question in the basic concepts of OBIEE

  Hello
  I'm prasanna Undapalli.I have question, can u please someone solve this problem.
  
  Can I use a backend of OLTP database to create a dashboard?
  
  Thank you inadvance.
  Prasanna

  Hello

  Technically you can use OBIEE with OLTP as well. However in real-world OLTP-related scenarios makes it difficult for OBIEE create OLTP star schemas. OBIEE is also an engine to run the analytical queries, while in most cases the queries generated on OLTP patterns are operational in nature. Best option is to use BI publisher and finish with OBIEE when querying against OLTP.
  OBIEE works with any database if you make do. If you want to follow best practices, its recommended to use with OLAP systems. Once all the OBIEE analytical reporting tool and OLAP databases are designed to the requirements of statement. For its always advised to use OLAP for better performance and more analytical of OBIEE.

  Bottom line, you can use OLTP with OBIEE, but performance will be a problem (not recommended).

• dressed in online test

  The practice test online OR current CLAD seems to be VERY different from questions of the test referred to in the messages in this forum, is there a FORMER practice online test and a NEW one? The current one is just for simple. Or am I missing something?

  Thank you

  Alan

  Not to be confused with the CLAD review is the review of basic concepts

  It is also a good preparation for the CLAD.

  When you take the CLAD, double check your answers. Don't let things like A = True and B = False travel you upwards. In addition, where more than one answer can apply can be tricky. Read them carefully.

• Setting up automatic SQL point doubt [OCP review]

  Hello

  Sorry for my bad English.

  
  I am preparing for the review of 11 g OCP.

  To do this, I bought training tools to help me prepare for the exam.

  But, in the chapter on the SQL tuning Advisor, a few explanations really confuse me.

  Excerpt:

  < <

  the auto tuning SQL job runs every night during the maintenance window.

  ( By default, labour made recommendations of profile SQL, them and them if they provide the best performance improvemen automatically implementst test)

  > >

  I was convinced that it was the opposite.

  I check several databases/documentation, and it is still seems to be the opposite.

  By default, the new profile of sql are tested but not automatically implemented (you must set ACCEPT_SQL_PROFILES to TRUE to enable this option)

  But the review is validated on oracle 11.2.0.1, and I 11.2.0.2/11.2.0.3 db available.

  So maybe oracle changed the value of the default setting in the new versions.

  Can someone confirm whether I'm right or not?

  I would rather accept what's in the documentation:

  "If a SQL profile is recommended, the database tests the new profile by running the SQL statement with and without the profile. If improving the performance improves at least three times, then the database accepts SQL profile, but only if the ACCEPT_SQL_PROFILES task parameter is defined on TRUE . Otherwise, automatic tuning reports of SQL simply report the recommendation to create a SQL profile". Auto Tuning SQL

  "If auto execution of SQL Profiler is enabled (only default is disabled), then the database implements all SQL Profiler that promise a great performance benefit. The implementation occurs to the time setting so that the database can immediately benefit from the new plan. You can enable or disable automatic execution using the SET_AUTO_TUNING_TASK_PARAMETER API to set the ACCEPT_SQL_PROFILES parameter. " DBMS_AUTO_SQLTUNE

• Basic instr (docs/bases not clear Oracle guide) question

  Hello
  
  I'm obviously quite new to this, but do not understand the more generally instr function, it's just the variable 'position' that confuses me a little, and the oracle documentation and manual review of basic principles are quite vague on this issue.
  

  INSTR(source string, search item, [start position],[nth occurrence of search item) the function returns a number that represents the position in the string source,

  tostarting from the given starting position, where the nth occurrence of the search item
  begins
  

  Examples

  Example 7-127 using Position of character to look forward to find the Position of a substring
  
  The following example searches for the string 'Corporate Floor', starting with the third character, for the string 'or '. He returned in 'Corporate Floor' position in which the second occurrence of 'or' begins.
  
  See THE INSTR ("Corporate Floor', 'or', 3, 2")
  14
  
  
  Surely these things are simply wrong?
  
  If the research started from the starting position given in the example from the oracle documentation, the answer would be 12, 14? 3 ('r') character to the second instance of "or" is inclusive, 12 characters isn't it?
  
  or have I totally misunderstood?
  
  Thank you

• concept between MS SQL and Oracle

  Hi, everyone, I'm very new to Oracle. Read a few books and confused about some basic concepts:
  in the world of MS SQL, you can install several INSTANCE on a physical server, in each INSTANCE, you can create multiple databases, each DATABASE has it is the log data\transaction the disk file.
  
  In the Oracle world, my understanding is, INSTANCE = structure memory + the physical database file (which is about identifying MS SQL). similar to MS SQL, you can have multiple INSTANCEs on each physical server. but who is the "DATABASE" in the oracle world? The closest I think is TABLESPACE. I can assign one or more physical data for each TABLESPACE files. but all the TABLESPACE set the log to roll forward inside the same undo TABLESPACE? In addition, for each application, I need to create one or more table SPACE inside an INSTANCE (it's what I usually do in MS SQL)?
  
  Thank you for your help. Please forgive me if my question is stupid.
  
  Published by: user3614365 on June 14, 2012 14:57

  Please forgive me if my question is stupid.

  Firs of all, your questions are not stupid at all. You can get better understand by defining analogies and comparisons with a product, with that you're familiar with one product. I used the same method when I learned about MS SQL comparing it with Oracle.

  So, welcome aboard the Oracle!

  in the world of MS SQL, you can install several INSTANCE on a physical server,

  You can have multiple instances of Oracle, belonging to the same or a House of Oracle on the same physical machine.

  within each INSTANCE, you can create multiple databases

  In the Oracle instance, you can have only one database. That's how it is.

  each DATABASE has it is the log data\transaction the disk file.

  Even in MS SQL there may be several files of data per database.

  Yes

  >

  >
  Here is little similarity between the Oracle TABLESPACE and the MS SQL database.
  In MS SQL Database has not only the files associated with it, it has its own security and piece of data dictionary. It can have its own rating, you can detach an instance and attach to the other, you can save some separately, etc...
  I'd say MS DB's unit "autonomous and self-containing", comparing to Oracle TS.
  Oracle TS is a way to organize the data files and definition some default of the common properties of storage for tables and other segments contained in TS.
  TS of Oracle have no separate security and data dictionary. Normally TS can be spare an instance and attached to the other. However, there is a special type of TS - transportable tablespace, which can be seen as a little more closely what is DB Ms.
  In any case Oracle TS is not even close to MS DB.
  And he does not need to be. It has a completely different purpose.

  In addition, for each application, I need to create one or more table SPACE inside an INSTANCE (it's what I usually do in MS SQL)?

  You don't have to. But you better to do this way, a point of view organization data. To make things look well organized.
  Sometimes a single application can use multiple TS, for example when he needs different block size for some tables.
  Also, you can share Costs between multiple applications, as you can do with MS DB.

  What else is different?
  There is no separation between the connections and users in Oracle db. It is an entity - USER. He has his security settings and can have its database objects.

  In Oracle, can only be a single scheme by the user, even named as a user. Basically it's the same thing - user and schema is the same thing and created and managed by the same CREATE/ALTER USER command.
  However, when we talk about storage and a place where objects belong to we say SCHEMA.
  When we talk about security and the owner where the objects belong to-we say USER. :)
  Schema is like Home in OS users. What the user creates belongs to his 'home' - the schema. And the user is the owner of it.
  If a user creates something of the other schema this thing belongs to the than the other schema and that another user will be owner, not the user who calls the CREATE statement.

  However, a user can change the current schema for the current session, for do not implicitly by specifying another schema as a prefix for the objects in this schema to another.
  CONNECT scott
  SELECT * FROM joe.emp;
  ALTER SESSION SET CURRENT_SCHEMA = joe;
  SELECT * FROM emp;

  In MS SQL schemas are more like directories, there may be objects of different users in the same pattern and the same user in different schemas.

  In Oracle, there are DB that is similar to the linked server connection.
  When it is called, DB Link is specified after the name of the object, separated by @.
  SELECT * FROM emp@anotherDB;

  That's the main differences.

  Oh yes, Oracle is a release management engine, and MS SQL's engine block, but it can be anything from the latter.

• Past 10g OCA/OCP test - no. $ class - OK to take the test of 11g upgrade?

  I passed the tests OCA and OCP 10g. We have no training $$s so I can't take the a required class to get the official status of OCP.
  
  It will be a problem if I also take review of upgrade of OCP 11 g? I'm hoping to pass the exam of the 11g in the coming months. I hope that we have $$s and I can attend an approved course next year and then complete the appropriate forms to get the status of official OCP 10 g and 11 g OCP. This sequence of events would cause problems?

  No problems.

  Only possible disadvantages could reduce the availability of some of the shorter and cheaper g 10 course that would suit the requirement. Sometimes 11g courses may be accepted for a 10 g OCP DBA, but check first.

  (It doesn't affect you, but to confirm it for other readers, the reverse is not true, 10 g training is not accepted for 11g certification OCP DBA... those with a drive of 10g will go 1z0-042/3 and then 1z0-050 (as you do)).

• Configure a load cell connected to multifunction DAQ

  I'm trying to connect a LCDH Omega 10 K scale by a module of constraint Dataforth SCM5B38-37 then AI0 gauge on a USB-6251 multifunction data acquisition.

  In addition to the load cell, the application will use a pressure sensor with a strain gauge bridge module plugged into AI1 to read the pressure of hydrulic.  The pressure transducer using a measure of the force will be calculated and compared with the reading of load cell.

  Currently, the USB-6251 box is configured to read analog voltage on AI0.  The scale is then performed using linear Fit.VI.

  Review the example Bridge - entry continues shows some additional controls may increase the accuracy of the reading.

  Unfortunately trying to use the DAQ Assistant only added to my confusion of the best practice in the acquisition of a signal from a load cell.

  __________________________________________________________

  Here are some of the questions I have...

  What is the best practice implement a load cell using a full bridge strain gauge conditioning module labview?

  What is shunt calibration?  Is this similar to the USB-9237 DAQ modules-specific?

  How do you know if your sensor is set up like a full bridge, half bridge, etc, the document load cell does not it?

  You can use the VI delete DAQmx perform bridge?

  _________________________________________________________________

  I don't know, I understand all the information of the map calibration either.

  Why is there resistance to entry and exit values?

  What is the value of the zero balance signafiance?

  Hello!

  I was looking into your question and found a few links that might help you configure your system. The first is a white paper that discusses some of the basic concepts of the gauges of constraint and their use with LabVIEW, shunt calibration and also covers some of the resistance values you see:

  http://www.NI.com/white-paper/3642/en/

  As you can see in this article, we have some specific hardware, built for the kind of measures you take. Because these devices are manufactured specifically for this application, they would provide better and more reliable results. That being said, you can configure your system with your USB-6521, it might not be as accurate as one of these systems. To set up your measurement system, rather than defining the analog input as a measure of deformation, you want to use the voltage custom with the option of excitement. This article treats this yet:

  http://digital.NI.com/public.nsf/allkb/C66F92BDE229F45A86257B6D004D6033

  We get you your data in the form of Volts/Volts (this document addresses more info on bridge probe scaling: http://zone.ni.com/reference/en-XX/help/370466W-01/measfunds/bridgescaling/), , but you should make sure you standardize this value to the excitement. Devices such as the NI 9237 provide the voltage and can take this known value in to account within the program, but you may need to do this manually for your application. Here is additional information on the NI 9237 and how it is configured to read information from strain gauge:

  http://digital.NI.com/public.nsf/allkb/892C84122A6501AE86257547007E5C53?OpenDocument

  Regarding the configuration of unit load and the information, you can try to contact the manufacturer for more information!

  Thank you!
