• Separate the VMkernel for pulse data store traffic?

  Hello.

  I was just reading Tech EqualLogic report 'Configuring iSCSI connectivity with VMware vSphere 5 and Dell EqualLogic PS Series storage' and saw something again on pages 3-4.

  Dell recommends to create a vmkernel port highly available on the subnet iSCSI serving as vmkernel default port for pulse data store traffic, so that the pulsation of data store traffic will then sit outside the iSCSI Software initiator and consumes any connection of additional iSCSI storage. He goes on to say that the traffic of pulsation of the data store will always use the lowest numbered VMkernel ports on the vSwitch.

  It makes sense, but this is the first I've heard of this. Everybody does that, with EQ or other iSCSI solutions?

  Thank you

  Brian

  
  

  Not sure that what talking about Dell, but the heartbeat "traffic" data store using the links normal iSCSI. Each host will have a file on one of the heartbeat data stores and open it which means there a lock on the file. The overhead is minimal and there is no need to worry at all.

• State Xperia Arc & data traffic Widgets switch becomes defective after update to ICS 4.1.B.0.587

  Hello to the team at Sony,

  I want to just give some food for my Xperia Arc last updated version ICS 4.1.B.0.587.

  After the update, as soon as the phone have been activated, if I can go in a screen or an application which requires me to turn the phone on side view landscape, subsequently, switch State and data traffic Widgets becomes elongated. (see attached photo)

  That is the only question I've experienced so far.  I used the switch Statue many turn on / off WiFi and Bluetooth.  I would just point out the issue and hoping that Sony came to suggest a fix sometime soon.

  

  Thank you for reading this message.

  Kind regards

  Joseph

  do not repair your phone by the CCP. Before that, you can try repair by closing the home app.

  Go to settings > applications > | all of the apps | Search Xperia - Home > tap and close. Click on the home button and the Launcher will be charging. See if that helps.

  Otherwise go to applications > xperia-home again and erase the data.

  If that didn't help then repair your phone by the CCP.

• RVL200 IPSEC: run together or some data traffic by tunnel, possible?

  Is it possible to run all the / some data traffic via an ipsec connection in tunnel using the RVL200?

  I have managed to connect routers ipsec RVL200 and RV042 and are able to connect to servers/computers behind it.

  Now I want to run some or all traffic through the ipsec tunnel for computers that are on the 192.168.1.0 network RVL200 subnet.

  Main office - router RV042 - 10.200.62.1

  -Router RVL200 - 192.168.1.1 remote desktop

  I am using the Advanced Routing option to add static routes, but I'm not 100% sure if I am setting up roads properly.

  To give an example of routing queries DNS for HOTMAIL.COM [65.55.72.183]:

  Destination IP - 65.55.0.0

  SM - 255.255.0.0

  GW - 10.200.62.1

  Hop - 1

  LAN - interface

  For some reason any that doesn't seem to work. I also tried to use the setting of the WAN interface and tested - it does not work.

  Is this possible? If someone has tried to do that, I'd be very interested to know how to configure it.

  See you soon.

  Linksys RVL200 or RV042 does not support the split DNS to the IPsec tunnel, which seems to be what you need. You might consider to upgrade the routers for the Cisco Small Business RV0xx routers that do not support DNS split on IPsec.

• Keep two very large synchronized data warehouses

  I look at the options to keep a very large (potentially 400GO) datastore TimesTen (11.2.2.5) in sync between a Production Server and [sleep].

  The replication was abandoned because it does not support compressed tables, or table types creates our closed code (without PKs not null) application

  1. I did some tests with smaller data warehouses for the indicative figures, and a store of 7.4 GB data (according to dssize) has resulted in a set of 35 GB of backup (using ttBackup - type fileIncrOrFull). This surge in volume should, and would it extrapolate to a 400 GB data store (2 TB backup set?)?
  2. I have seen that there are incremental backups, but to keep our watch as hot, we will restore these backups and what I had read and tested only a ttDestroy/ttRestore is possible, that is full restoration of the full DSN every time, which takes time. Am I missing a smarter way to do this?
  3. Y at - it other than our request to keep two data warehouses in the construction phase, all other tricks we can use to effectively keep the two synchronized data stores?
  4. Random last question - I see "datastore" and "database" (and to a certain extent, "DSN") apparently interchangeable - are they the same thing in TimesTen?

  Update: the 35 GB compress down with 7za to slightly more than 2.2 GB, but takes 5.5 hours to do this. If I take a fileFull stand-alone, it is only 7.4 GB on the disc and ends faster too.

  Thank you

  It must be a system of Exalytics, right? I ask this question because compressed tables are not allowed for use outside of a system of Exalytics...

  As you note, currently the replication is not possible in an Exalytics environment, but that is likely to change in the future and then he will certainly be the preferred mechanism for this. There is not really of another viable way to proceed otherwise than through the application.

  With regard to your questions:

  1. a backup consists mainly of file of the most recent checkpoint, more all the files/folders that are newer than this file logs. Thus, to reduce the size of a backup complete ensure

  that a checkpoint occurs (e.g. "call ttCkpt" a ttIsql session) just before starting the backup.

  2. No, only the restore is possible from an incremental backup set. Also note that due to the large amount of rollforward needed, restore a large incremental backup set can take quite a long time. Backup and restore are not really intended for this purpose.

  3. If you are unable to use replication, then a sort of application-level synchronization is your only option.

  4 data store and data mean the same thing - a physical TimesTen database. We prefer the database of the expression of our days; data store is a legacy term. A DSN is something different (Data Source Name) and should not be swapped with the data/database store. A DSN is a logical entity that defines the attributes of a database and how to connect. It is not the same as a database.

• A SCN for the entire database and the different SNA for the data files?

  DB Version: 11 g
  
  I always thought that there is a unique SCN for the database as a whole.
  A quote from the link below as
  When a control point is completed, Oracle stores the RCS individually in the control for each data file file
  http://www.dbapool.com/articles/1029200701.html
  
  
  What does that mean? There is a SNA for the entire database, and there are individual SCN for each data files?

  Well, unfortunately, the article says more bad than good things. Or if I can't call them wrong, they are rather confusing and rather than clear things for the reader, its making them appear to look more confused.

  First things, YVERT is used for read consistency (CR) mechanism and the backbone of the notion of Multiversioning. The control point is the mechanism to help that recovery is decided. Contrary to what said article, not any kind of checkpoints update both the data file and the control file, and also, there is not a type of them as well. In addition, the article says that the LAST_CHECKPOOINT is set to NULL, while its actually set to the infinity since it is not possible to detect the moment when the database is opened, that the last issue of control over the file would be. In the case of complete control point, this number is saved and is also associated with the toa Controlfile own database leader at the next startup. If this is not the case, there is an inconsistency in the stop_checkpoint of the data file and the stop_checkpoint reocrded in the control file, leading to a recovery of the instance.

  There are several types of control points. Similarly, there are several types of SNA as well. Without going into the details of these, IMO, the article simply means that when the control point write over a file passes, oracle updates the file checkpoint on it and this is recorded in the Controlifle. as well.

• Automatic switching of WiFi in the cell for the data not work, requires a restart of the phone

  The phone is a peak of Geeksphone, and the version of the operating system is 1.4. The problem is with the automatic switching of the WiFi to cell for my data. If I take the phone outside the WiFi range, it does not acquire the data (2 G, Edge, H or 3 G) signal and so I have no data. I left for hours without success. The only solution is to reboot the phone, then outside the configured WiFi connections and it will collect data signal. When I re - get the WiFi area, it captures the network and without problems.

  I also had this problem with version 1.1. I upgraded to think it could be fixed, but he did not.

  Thank you, Ralph. There was an update available which appear not yesterday. After the installation, I get the options that you quote, namely to turn the cell data in the notification area. Thanks a lot for the tip and the quick response.

• How to create a Subscriber variable to the network & OnDataUpdate for Variant data type?

  Looking at the example C:\Documents and Settings\All Users\Documents\National Instruments\MStudioVS2008\DotNET\Examples\NetworkVariable\Basic\cs\Subcriber.2008, how can I create a subscriber to the network variable and OnDataUpdate for Variant data types?

  I solved it by using the correct data type in .NET, for example an sbyte to CVIInt8.

• Filter for table data, the range of data obtained and defined 2D

  I produce data of an ultrasonic sensor at 1 K Hz, and there is a lot of data (data points range of 0 to 10). However, in some cases when I know that the data should be about 7 (for example) I get outliers (about 9 and 10). Is it possible to define a filter for data in the defined range.

  I averaged the data to get an average value, and outliers are distorting. In the worst case, my outliers are 30 to 40% of the data generated. I created a filter to sort the data and, taken from the lowest value. I stop the loop when data reaches a value greater then 9. But this seems to take a long time (because the loop checks for each data point and there are 1000s of them).

  Is there a better way to filter data and define a predefined table range to collect?

  I enclose my filter.vi... and a set of samples of my previous data. The ranges of data of 10-8 and would like to have the range 7.5 to 8.5 to consider. The sensor records tension here and the problem can be solved by installing a different type of sensor, but if a filter in LabView can due it, the sensor that we use now is absolute.

  I am in kind of emergency, my design in unfinished because of this problem, if someone can find some time to share some suggestions, I will be grateful.

  Thanks in advance.

  See attachment.  I have incorporated the data you've posted in the vi.  It doesn't seem like any data were less than 8.7 or so, so I modified the scope so it would be a few points on average.  Some games were completely out of reach while the average came back like NaN (not a number) due to a division by zero.

  ...
  

  Let's say that the period is 21.10.2014. -23.10.2014. and I want to get the last balance recorded for zone 1. for each day. The result should look like this:

  Date         Time      Location  Box  Balance
  21.10.2014.  15:00:34     1       1    1237
  22.10.2014.  22:00:00     1       1    6742
  23.10.2014.  23:57:12     1       1    25
  

  So far, I managed to write a query that gives me the balance so that a SINGLE date (date more time in the table), but I need balance for EACH date in a specific period.

  My incorrect code (has not managed to implement "BETWEEN" for the dates...):

  SELECT TestTable.[Date], TestTable.[Time], TestTable.[Location], TestTable.[Box], TestTable.[Balance]
  FROM TestTable
  WHERE Time=(SELECT MAX(Time)
  FROM TestTable
  WHERE Location=1 AND Box=1 );
  

  TNX!

  NP

  Here's the correct query (just copy - paste):

  SELECT
  T1.Date,
  T1.Time,
  T1.Location,
  T1.Box,
  T1.Balance
  FROM TestTable T1
  INNER JOIN (
  SELECT
  MAX(Time) AS Max_Time
  FROM TestTable
  WHERE Location=1 AND Box=1 AND Date BETWEEN #10/27/2014# AND #11/1/2014#
  GROUP BY Date) T2
  ON T1.Time=T2.Max_Time;
  

  The problem is in the SELECTION within the INNER JOIN. This SELECTION selects the time max for each date, because we want this and then the entire table, we choose filelds we want, but now we have only fields with the time max.

  Here is a really good explanation of INNER JOIN if anyone is interested--> JOINT INTERNAL

  Peace!

• Why I see Runtime Error R6016-not enough space for thread data?

  All of a sudden when I try to launch Google Chrome, I get "error R6016-not enough space for thread data? ' like Chrome stops. Plenty of hard disk, disk defragmented, no viruses or malware. Never seen this message before.

  I think you're on the right track to reinstall Chrome... but they have a method of choice for the best results and that the information is here:

  http://support.Google.com/chrome/bin/answer.py?hl=en&answer=111899

  Just FYI, running sfc/scannow won't help, but it will waste your time and you will not be able to determine which file is causing the problem because...

  When sfc/scannow runs successfully, you will see a start and complete message in the Event Viewer log system.

  It can take a long time to run and slow down your system.  When it starts and stops correctly you can only see events like this in the case where the system log viewer:

  Event type: Information
  Event source: Windows File Protection
  Event category: no
  Event ID: 64016
  Analysis of file File Protection Windows has been started.

  Event type: Information

  There is no information about what he did or what he did not.

  Even if sfc/scannow finds something to do, you will not know about it.

  That's why try again more than a waste of time.

  I start working with the CRio-9012, I want to know how to transfer data from the FPGA RT, I found something about DMA FIFOS, however I notice that it is only possible to transfer pictures, I don't know if I'm doing something wrong.

  Yes, you will need to use 'Host to Target' or 'Target to Host' (the FPGA is the target, RT is the host); the one who depends on the direction that where you want to send the data.  Target range is for FIFO that is used only on the FPGA. they are useful for transferring data between the simultaneous loops in FPGA code.
