standards - SCSI sense data formats and MODE SENSE control page -

-

SCSI Reference Manual defines two types of meaning data formats - fixed and variable descriptor-based ones (Chapter 2.4).

"control mode page (0h)" (4.3.8), as the answer to the MODE SENSE SCSI command Return is considered to be a D-SNSE bit, which is defined as follows:

DCSEX (DCRIPTOR format sensing data) bit

    < Li>

    0 sets a descriptor format data data (D_SENSE) beat zero that the device will return the server fixed format meaning back to the data At the same time I_T_L_Q data as a check condition status in Nexus transaction.

  • A D_SENSE bit set for 1 specifies that the device will return the server descriptor format meaning data when in the same way I_T_L_Q returns the return data to Nexus transaction as the status of the check, Except as defined in 2.4.1.

    My question is about this bit interpretation on the SCSI target side - if this is a bit 1 then what is the purpose of the server to return the meaning data in the descriptor format Is liability ? Or is it only a probability wants to back it up in any format?

    The first byte of the meaning data can be used to determine its format, so the SCSI initiator does not really need the D_SENSE bit value to decide whether to decode the obtained knowledge data. for.

    I am asking the reason for this question because I am working on some software which is to simulate a SCSI goal, to make it right, I need to digest many SCSI documents.

    If the SCSI target implements the ability to set this bit, then it can either be able to return to the meaning Should have formats SCSI targets can not be chosen to provide this bit for reading and writing, and then decides how this format gives it.

    Please also keep in mind that the "mask mode" is the window page for SCSI compliant, which shows that the bits of any mode page are capable to be set.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
