Put in read-timeout = 0 in the customer pool of gemfire cache xml

Hi all

What is the result to read-timeout = 0 in the customer pool of gemfire cache xml

For ex:

< name of pool = "testPool" read-timeout = '0' attempts = "5" >
< host = 'test' port = "1000" / >
< / pool >

I ask because of this bug note of http://www.VMware.com/support/vFabric-GemFire/doc/BugsFixedGemFire66.html

12/02/07#36349Client gateway region.put () ends without exception, but the input value is not updated at the server level5.0closedValue of the entry to the server is not updated, although customer region.put ends without exceptionThis occurs when the operations are performed on the server down. The problem arises from this sequence of events: 1. a client attempts to set the X value one or more times, but each attempt times out. 2. each attempt failed "orphans" a thread on the server. 3. the customer chooses a new connection (and its associated server thread) and continues to perform its sequential (X + 1, X + 2 updates... X + n). 4 orphaned threads are subsequently demand and successfully put it with the value X, overwrite the values previous (X + 1 or X 2 or X + n).

Disable the behavior of time-out for the BridgeLoader, BridgeWriter or BridgeClient by setting its "readTimeout" zero setting. This causes all operations in the region managed by the client to block until the server has finished with operation, preserving the customer order. The configuration of "retryAttempts" will always be used when there are failures in communication with the server or when the server cache closes in the middle of the operation.

This problem still exists with gemfire 6.5.1?

Thank you

You are welcome.

To clarify, read-timeout = 0 not cause the customer to always block for gemfire 6.5?

No, the behavior of the read timeout has not changed, this will cause the client to block forever. It is just a workaround for the problem that you referenced. This issue, ticket #36349, has been set, it is not necessary to use the workaround more. In other words, you must set read-timeout to 0 to work around this problem.

  • LabVIEW FPGA. Where should I put the custom controls - or type defs in a project

    Hello

    Maybe this is a stupid question - but I'm a little confused on where within a project I should put the controls (or type defs) used in FPGA screws.  If you put in the bit "module FPGA" project, so they come up as "dependencies" - as if they are not in the project within the project when you read/write values in the target FPGA.  Also, it seems that if you copy the project to a different location folder then the FPGA vi can be distributed in a way that she needs to be recompiled - even if you don't change anything - that's not cool if it takes an hour or two to compile.

    I had the controls in the external project for awhile - but seems not ideal from the point of view modular programming, and also, it seems that it may also cause the recompilation unnessary - although perhaps less often that put them in the FPGA subproject.

    Any thoughts?

    I've seen the same behavior and it is a fact that the code must be recompiled if you move a project even if the FPGA code is unchanged. From my point of view, it's a real BUG. This is independent of any file source or target FPGA.

    The other point of your question is not clear relly. Of course, you will get the dependencies if you place the necessary files outside the structure of the target project. But I see no problem to reference them twice because it won't double the source itself. So I suggest to refer to these files several times in the project structure. Actually I'm doing this because I manage a project file LV with different targets CRIO where the complete code for the target FPGA is double referenced under each target.

    In both cases, the audio device can only deal with a stream at the same time. Everything you put into it will come out, we cannot dissociate the sources. If you have 2 choices:

  • Problems of JavaScript when delivery to the customer using Acrobat Reader XI

    I am working on a form for a client that takes an array of values for radio button, apply a weighted percentage and create a partition for each row in the table. The score is then harvested at the end of each of the two tables. In the end, these two scores get on average in the last line on page two and one result 'Action A complete' or 'Complète Action B' appears in a field of text next to the partition. The whole thing works beautifully after several revisions. Or rather, it works beautifully in the drive of DC and DC Pro. When I send to the customer who uses reader XI, the last line (if/script, then the average of the two scores and action of text) must not be calculated. Any help would be appreciated. It is all confidential activities of a client so I cannot view the actual file, but can share snippets of code for java.

    None of these scripts should work in Acrobat or reader, because they contain several syntax errors.

    First, you use an invalid operator, namely "=>". You should use ' > = '.

    In addition, you have 2 other errors that I can spot. In the second script you use the property valueAsString but then you treat what she returns (the variable 'q') as a number. Is not IT a string. So what you should do is converting it to a certain number, like this:

    var q = Number (this.getField("AScore").valueAsString);

    And in the first script you use a variable which you ever reported ("n").

    If solve you these problems, it should work in Acrobat and Reader.

  • How could put editable report column as read only based on the other domain

    Hello world

    I'm new to APEX. I have a modifiable tabular report (SQL query). When I choose the column (which is a selection list) of a certain value, I want column B to be read-only (depending on the result of an another SQL described below). It doesn't seem to be a READ ONLY section in the type of tabular report where I could put my SQL condition.

    In other words, "column B" must be read only based on SQL returning following true or Exists:
    Thus, to determine if column B is ready only, I need the following logic:

    SELECT 'x '.
    of tab1
    where key = (value of column A)
    and the flag = "Y".

    Any help would be greatly appreciated!
    Thank you

    You can only do so if your tabular presentation is a manually created. In this example, it shows how to set this property:

  • VISA: (Hex 0xBFFF0015) timeout expired before the operation is complete.

    Hello

    We use LabView to control a sequencer of high-voltage (HVS448LC 3000 D) LabSmith using LabView drivers from the manufacturer, power supply. Everything works well in our program (attached) until we try to use another program on the computer at the same time. For example, if we try to open a window for our camera, or even a folder in Windows, the program gives the following error:

    1073807339 error has occurred in the CITATION read in FromHVS448.vi-> CommandHVS448.vi-> RegulateVoltage.vi-> Gated timed injections version 06.the vi

    Possible reasons:

    VISA: (Hex 0xBFFF0015) timeout expired before the operation is complete.

    We would like to be able to control the camera software and the power of LabView by using the same computer, but we do not know what could cause this problem. We would appreciate any suggestions! Thank you!

    You should really put a lot of orders of pre-instrumentation in parallel.  Force an execution order by using the wire of the error.  Serialize all commands to the instrument.  You may have an order interfere with one another.

  • VISA READ timeout error - several GPIB resources

    Hello

    I'm working on a network 3 GPIB instruments (Optical Attenuator, amplifier in fiber, spectrum analyser), controlled using VISA sessions in Labview. When it is run separately, the three corresponding screws (which are located in three different Labview projects) works as expected. However, when they ran at the same time, one gives them timeout-1073807339 VISA READ errors. These errors seem to occur when another instrument is sending / receiving data / instructions at the same time that she is.

    The exact context of the error is either:

    -an another VI is running, which includes sending several requests and responses every 100 ms, reading

    -by failing VI starts, I get an error of waiting time among the first Subvi containing a VISA READ operation to perform (sometimes initialize.vi (in situation 1), sometimes one of the subVIs connected the rest State (State 0) on the time-out of the structure of the event).

    or:

    -the default VI is running,

    -by starting another VI, which includes repeatedly sending requests and reading the responses, the failing VI up a mistake among the first Subvi containing a VISA READ operation to run (one of the subVIs linked the State of rest (0) on the time-out of the structure of the event).

    What I tried:

    -gradually increasing the delay between the VISA WRITE and READ operations to the relevant instrument (from 10 ms to 10 s), without success. More surprising are my observations which, by operating this single VI, increasing WRITE it / READ delay results in the same timeout errors. I have found no mention of such behavior through research google and forum. I hope that this may point to a solution to the main issue,

    -switching between synchronous and asynchronous VISA WRITE / READ operations.

    -reorganization of the network GPIB to a star to a linear topology topology (three instruments have different GPIB addresses in case anyone is wondering).

    My thoughts:

    It seems to me that the error is related to a delay introduced between a VISA request and its read operation by the transmission of another query associated another instrument in the same network GPIB. But I have no idea why pass a query to another instrument would introduce such a delay, or why this delay would result in a timeout error (and only an instrument, while writing / reading in each pilot screws are basically the same). Hopefully a more experienced Labview-er will be able to shed some light on my problem.

    Included is the project that contains the default VI (main.vi) and the driver custom made use of.

    There are a number of ways. If you want to keep separate projects for instruments, you can use semaphores often slandered around calls for screws in each project. Locking is not expected or predictable, but it would give controlled access to the GPIB resource.

  • A matter of design using the custom in custom frames fields.

    A matter of design, which is a good implementation of the following?

    I read the articles in the Knowledge Base 'Create custom fields' and 'Create a custom handler for a screen presentation' and what I want to do is control any arbitrary custom field - a Manager custom.

    For example, if I have the following fields:

    1. Field
    2. Field
    3. Field
    4. Field
    5. Field

    I want the second and fifth fields to have a different margin, filling or the width of the first, third and fourth fields, I would by methods layout() and object to the second and fifth fields - which shall replace the custom method of the sublayout() Manager logic?

    Or can I add logic in the custom handler, I find the fields with the method getField() to get the second and fifth fields and change the margin, filling or width with the logic in the custom handler?

    What is the right place to put the logic?

    Thank you.

    the field can only work with the space assigned by the Manager. how he uses this space is to the field, he could see itself smaller, for example.
