• Confusion about the Source of excitement in the bridge SMU-4331 input module

  Hello

  I had some confusion through the input of the bridge SMU-4331 sheet module.

  In the features section of excitement, its current Minimum as 29mA says. What it means. It can only current greater than 29mA delivery!

  

  I think this should me Maximum current specification.

  If you look at the table below

  

  350 ohm resistance, the current should be 10V/350 ohm = 28.5mA

  but for 1 K ohm, current will me 10V/1Kohm = 10mA, which isn't normal, if you specify current minimum as 29mA.

  any thoughts?

  Kind regards

  Hello Mirash,

  I'm glad I could help!

  As for your other question, the SMU-4330/4331 are inherently peripheral ratiometric.  This means that they are designed to detect the level of excitement and range of the ADC to the appropriate scale.  In this way, we can compensate for permanent changes in the voltage.  One of our engineers wrote a big article really nice area on the subject I would recommend that you take a look at: Sensors of Measuring Bridge-Based with the ratiometric approach

• Confused about the notion of VLAN

  I'm confused about the VLAN. I thought that the notion of VLAN was this computer on different VLANS were not suppose to be able to communicate with each other. I am setting up a 6248 and for me to get DHCP to work, I need to enable ip Routing. When I turn the routing ip, all computers on different VLANS are able to ping each other. Is - it the way it was suppose to work, or am I missing something?
  MGMT is on vlan 4093
  DHCP is on VLAN 100 trunk e34 10.10.1.1

• Extremely confused with the extremely complicated presentation of BlackBerry applications

  Please help me, I'm very confused with the extremely complicated presentation of BlackBerry applications.

  I made an app, the name is "App", I got signed and downloaded the App using the emulator Ripple, with the word 'HelloWorld' signature (password not true of course).

  Now, I do another application, with the name of the App (B) I CAN'T use the same HelloWorld signature password because the emulator Ripple said "Oh, Snap!" Build request failed with the message: [ERROR] error: Code signing request failed because this version of the application or the package has been previously signed. If please increment the version (s) and try to connect again. »

  Now, I don't understand and I am EXTREMELY confused with the presentation of the model of application for Blackberry.

  I should first request, for an another RDK and COMINCO files create a new signature for App B password?

  Or should I just increment the bundle version? the problem is when I tried it on Blackberry server seems to give narrations of error message that the APP ID is already used.

  Okay, I'm officially stuck and I don't know what to do. Can any developer of blackberry here or the official employee blackberry tells me what I need to do?

  Thank you.

  I do not use ripple either but can see what the problem is (nothing to do with the ripple)

  Open your file config.xml for the new project (probably copied 'App A'?)

  In the widget section, change the id to something different, for example com.example.AppB

  Save - reload the ripple and make sure you have the new ID in the Config-> Widget

• Formula to calculate the SGA for 12 c of OLTP database

  Dear Experts,

  What is the formula to calculate the SGA for an OLTP database application.

  This will surely depends on several variables such as

  (1) the maximum number of connections application would have

  (2) growth of database

  • users connected
  • Server connections
  • total number of connections
  • connection memory
  • OS/application memory

  Thanks John.

  Is below the formula makes no sense?

  Why thank me when you don't know what I said:

  You will not find a formula.

  You formula has nothing to do with the numbers suggested for EBS, which could (only "might") be a reasonable starting point. You have not given any indication of how you arrive at these figures. You just apply that 80% of the RAM formula suggested by Mr. Faruq? If so, you might want to ask him how he justifies the algorithm.

  One point, that you should study management PGA. Your formula assumes that all connected sessions required 30 MB of RAM, all the time. How can you come to this conclusion? On your development system, you can observe how PGA is necessary for the optimal performance of your queries. Then you can ask "how many sessions is actually running a query at the same time?", adds on the non-negotiable PGA by session and calculate the requirement on the PGA TOUR as a result. You should also think about what you call ""memory connection ' and what you call 'PGA Pool'. " These aren't words that I know.

  Thank you all...

  its 32-bit, this means no chance to increase the SGA by increasing the kernel parameters? is this correct?

  Oracle on Linux 32-bit can be used up to an LMS (if I remember correctly) 16GB. You start the PAE kernel, and then configure your cache with use_indirect_data_buffers and db_block_buffers. Your pool will always be limited (even once, I forgot the details) to something less than 2 GB.

  Takes back me a few years.

• IF database-> RAC database: estimate of the size of the SGA for each instance

  Hello!

  Let's say that there is a single instance with SGA 100 G size DB (assume this size is optimal for this database).

  If this database is intended to be converted to a RAC database with 2 instances (suppose DB workload will be spread over multiple instances).

  How to estimate the needs of SGA size for each instance in the RAC database?

  It takes 50G + General cool CARS (say 15%) for each instance?

  (Do not consider situation when one of the instances has failed, and all the charge redirects to an instance having survived)

  I'd be grateful if someone has offered or provided useful references.

  ---

  Kind regards

  Kyrylo

  As a general rule, I would size the SGA on new nodes to 120% of the SGA to single instance. Yes, this means that you will more than double the size of the SGA. You will need additional space to hold the load memory Cache Fusion. And the buffer Cache are possibly a little more space to store additional versions of blocks that seem to accompany the many implementations of CARS. Now, it's just a rule of thumb, so it has a high degree to be very wrong.

  You'll want to consider two big things... (1) the service being used. Will you take advantage of the services to perform the partitioning application? If so, instances can see various workloads that can lead to requests for different resources. (2) you will support a kind of failover (TAF or manual failover) applications? If so, then the LMS must be sufficiently sized to support the additional workload.

• Confusion about the size of the array in Oracle 11 g

  There is confusion about the size of a table. When exporting schema 'CRESTELWOMPRD601', the log file shows:

  _____________________________________________________________________________________

  . . exported "CRESTELWOMPRD601." "' TBLRSUBSCRIBERFIELDWORK ' lines of 12.62 GB 35568

  ____________________________________________________________________________________

  which may involve the size of the TBLRSUBSCRIBERFIELDWORK table is 12.62 GB.

  But when I find the size of the table using the query:

  SELECT nom_segment, BYTES / 1024 / 1024 "SIZE (MB)" FROM dba_segments where owner = 'CRESTELWOMPRD601' and nom_segment = 'TBLRSUBSCRIBERFIELDWORK. '

  He said that the size is only 9 MB for the TBLRSUBSCRIBERFIELDWORK table.

  I hope that my request is clear that there is no clarity on the size of the TBLRSUBSCRIBERFIELDWORK table.

  Please get back with the answer to my query

  
  

  Concerning

  Dba_segments indicates the space allocated to the segment while expdp indicates the size of the exported data, so if you had a table with a measure of 1 MB, but no data, dba_segments would 1 MB and expdp would report 0 bytes.

• How to set the SGA / PGA or memory target for the database

  Hello

  We use on AIX 5.1,6.1, oracle 9i, 10g, 11g

  Currently, we manage the databases on the default memory which was chosen at the time of the creation of the databases.

• Confusion between the physical schema definition MSSQL Server

  Hello
  
  I'm learning ODI 11 g and I am currently working under the physical definition of the schema under topology Navigator. I want to import data from MS SQL Oracle Server; I have defined the source (MSSQL Server) and target servers (Oracle). Testicles of connections and that they are working correctly.
  
  When you set the physical schema for MS SQL server I am confused with the following fields. Can someone help me understand its use here? I'll be very grateful
  
  (1) database (catalogue)
  (2) owner (schema) here I read-only user which I already defined as part of the definition of the SQL Server. It does not appear in the list.
  (3) database (catalogue of the work)
  (4) owner (scheme of work)
  
  Best regards
  Muhammad

  >

  Work catalog database is the location of the temporary objects of ODI (for example, C$, $ I, I have$ tables etc.)
  == I use a single user reading to read the data. How ODI creates temporary objects in SQL server. My work and master repository is the Oracle database.

  Temporary tables are used for a number of things, remember that at this moment in the topology - ODI don't know if your connection to the SQL Server is a source or a target, so he wants all the details, just in case. Reasons for Temp of source tables might be:
  Source of the joins of tables in different data sets with a staging expliitly, set on the source.
  Format (change data capture) objects - Tables to langer, newspaper views (items of $ J) etc.
  If you use only MSSQL tables as sources, you proably find no temporary object created side soruce, arrays of C$ will go into the scheme of work target (in this case, Oracle) that the I'll tables$. So in your case, it's normal.

  Scheme of work is the owner of the database value (catalog of the work) - once again, usually of dbo.
  == use dbo as sys in oracle?

  Type-IIRC no matter what user to the sysadmin role that creates objects have these objects as dbo by default.
  Im not MSSQL DBA if.
  Think of it as a qualifier that ODI will use when generation code selection based on the mappings of interface (for example select database.catalog.table xyz) etc.

  Hope that helps

  Krishna

  First check the memory on each node, if you have enough memory then (assuming spfile shared for all nodes)

  create a pfile='/tmp/initbackup.ora' of spfile; ---> To save.

  alter system set = 8 g sga_max_size brought spfile sid ='* ';
  ALTER system set sga_target = 8g brought spfile sid ='* ';

  on node 1:
  srvctl stop instance d -i
  srvctl start instance d -i

  Then check the sga

  Repeat the same steps for different nodes

• Confusion between the theories of computation

  Hello
  
  I confused with the notion of computation Essbase as States of SER60 who, for scripts of calc optmtal DIFFICULTY on members in the order of (Dense in first and then scattered) hour glass model m... However, according to what I read in a blog, he states that FIX is supposed to be used on sparse and if its inevitable to fix on the dense members then dense are supposed to be in last place in the order...
  
  the given reason was that sparse setting first reduces the number of blocks in memory and then dense members would be filtered from these final calculation blocks...
  
  Can anyone help clear this confusion?
  
  Thanks in advance

  Could you give links to or cite references of SER60 that you mention?

  Anyway, dense fixation will not reduce the number of blocks processed, but he could still improve performance and make a script more readable in various situations. A big one, is that a FIX on dense can prevent dynamic Calc. Members assessment in your building. The order of the dimensions in the FIX should be irrelevant, because Essbase restocking. So ' last dense "shouldn't matter.

  There is a very interesting discussion here: http://www.network54.com/Forum/58296/thread/1208974485/Order+of+Fixes+-doneit + material. Edward gives a good example of a script that can be written more efficiently thanks to a CORRECTION on dense (that OBVIOUS).

  Incidentally, I think Ben White should be stored members setting won't always prevent the evaluation of dynamically calculated members (all depends what else stored reference formulas, see FRMLRTDYNAMIC also PUT in the Ref Tech documentation).

• Confusion with the implementation rate Comp

  I'm a bit confused with the implications of fixing the rate of the wrong frame.  My camera can record to 23.976 however the manufacturer sometimes mentions this parameter as 24 p in the manual.  I read that there is no harm using 24 p if the model is a bit long second.  But questions arrise if the model is longer and you are being followed.  On the other hand, mocha specifies that you be specific in the choice of your pace.  The difference.024 makes a real difference?

  If 24 fps is the standard film why camera makers made their record of cameras at 23.976, or film also just named its 24 p and 23.976.  23.976, 24, 25, 29.97, 30, 59,94, 60, they are all so close

  Also, what are the consequences of ripping out at a different pace

  Thanks in advance

  Thanks in advance

  You can blame the TV standard NTSC color for the odd frame rate.  At the same time, it was really 30 frames per second.  These are the days of TV in black and white ONLY.  Engineers worked mightily to get to a color system that was compatible with existing B & W games millions, and they finally got it.  But to answer a color signal, they need a little bit more information in each image. The NTSC signal was already packed and needed something to give, so they slowed down the pace a bit.

  Thus, 30 images/s became 29.97... and in direct proportion, 24 fps is 23.976.  Just learn to live with it.

  "Yes, well how can you avoir.976 of an image?

  You can not.  But a frame does NOT miss a count of the number of frames in a second. It's really a MEASURE OF TIME.  PAL-Land, a frame is 1/25 of a second.  In Hollywood, a frame is 1/24 of a second.   In days of yore NTSC, a frame was 1/30 second.  But since 1953, 1/29.97 second.

  Don't obsess over 29.97 and 23.976.  Just use them and get used to them.  Do not put 29.97 images in a model of 30 fps, or 23.976 images in a model of 24 fps just because you like whole nice.  If you do, the movement of the images you shoot can go all twisted up.  Do not.  Do not.

  End of sermon.
