Slow iSCSI-IP connection between ESXi and DataCore Virtual storage via 10 Gbit cards
Hi all
at the moment, I have test the following configuration:
Site #1: DELL PowerEdge R730xd with 10 Gbit NIC and DataCore-V DataCore Virtual Storage under ESXi (vSphere 6.0.0 build Standard, 3380124)
Site #2: Apple MacPro6, 1 with 10 Gbit NIC and ESXi (6.0.0 vSphere Standard, build of 3380124)
DataCore # 1 server has a disk via iSCSI to ESXi on #2. The connection is running. Up here, so good, but for example when I start a Storage vMotion on #2 of local SSD on the iSCSI disk, speed is exactly 1 Gbps. interesting is that the speed increase when I start a second Storage vMotion and still when I start a third Storage vMotion etc. This behavior is clearly visible in my attached screenshot.
To me that sounds like to it no matter what iSCSI-IP connection is limited to 1 Gbps.
All the components used are certified VMware.
Any ideas that I can check for this problem?
Thank you very much
Migo
The reason for this behavior is that the MacPro6, 1 has two interfaces of iSCSI software that points to a DataCore frontend. It is not allowed. After you have disabled the second interface of software iSCSI, growth up to full 10 Gbps speed.

Bluetooth connection between iPhone and iPad
My iPhone 6 does not connect to my iPad via bluetooth.
I previously used the bluetooth connection between my iphone and iPad to connect the iPad to the internet. Despite the two devices were among the recognized bluetooth devices and they were previously linked/partner, it was not possible to establish a connection.
Perform the actions recommended for repair/reissue apple support - 1. Toggle bluetooth, 2. turn on/off the unit, 3. remove the iPhone/iPad bluetooth connections - 4. Reset network settings - 5. Reset all the settings-, nothing works.
IPhone/iPad devices isn't even on the list of bluetooth devices available on the iPhone, or iPad. Everything that happens is the animated icon turns all the time.
Deleting a connection to a device and bluetooth speaker/amp from the pairing of the speaker/amp system process made a new connection.

Localhost UDP connection between FCR and Matlab
Hi all
I have a question about the connection between Matlab and FCR UDP. My idea is to Exchange data between Matlab and Labview on the same computer.
So I found the 'UDP Simple' of the FCR 2.0 sample project where periodically a datasample is generated randomly and sent to the remoteport 61557 local host. In the project a 'fractional number of string for transmission' is used for the transmission of data. The receiver of the sample project reads from the same port to receive the datasample.
Now, I'm interested to read this simple stream from Matlab (just at first), however, it does not work and I'm not sure why. What I do in Matlab is the following (code Matlab)
delete variables;
u = udp ('127.0.0.1', 61557); % Of installation UDP Object
fopen (u); open reading port %
A = fread (u, 1); % read an element
fclose (u);With this code, however, I get a timeout by saying: "' WARNING: unsuccessful reading: the amount of data specified has not been returned within the time limit." "
I'm not sure why this happens, maybe you could help me out here? I guess that the formet serving to VCF is not the same as in Matlab? Maybe the Terminators are not the same?
See you soon,.

Hey
So, regarding the problem actually, I found the solution today. It was not the firewall, but a simple configuration in Matlab seting the UDP port. So the side of Matlab, to change the definition of udp object according to
u = udp ('127.0.0.1', 'Thelocalport', 61557);
If you have
u = udp ('127.0.0.1', 'Thelocalport', 61557);
fopen (u);A = fread (u)
fclose (u);
Delete (u);Who does the trick and you can read from the port. Then of course you say Matlab that you read from the "LocalPort" x, which I wasn't aware of.
On the transmitter side, you simply:
u = udp ('127.0.0.1', 61557);
fopen (u);
fwrite (u, '1');
fclose (u);
Delete (u);Here, you set just the port of transmiting.
About the format of the data: I used the simple UDP protocol streaming Comms project where a random number is generated as a double, transformed into a string (ASCII values) and transmitted. At the level of the receiver, you get as much the UDP packet with the ASCII values that you must turn if you want to find the number.
I hope this helps anyone having the same problem.
See you soon

Establish a persistent connection between client and server
My application must keep in touch with my servers, the HTTPConnection gives the ablitity to make one request per connection. Then the HttpConnection might not make persistent connections in the BB.

Daniel,
The problem is that you are using the ODBC Postgres driver for the HS_FDS_SHAREABLE_NAME parameter, but this must be an ODBC driver manager and not the driver ODBC Psotgres.
Go to the.Click the 'Download' and follow the instructions to download the 2.3.1 pilot and make libraries and programs.
Once this is done, then use the driver as parameter HS_FDS_SHAREABLE_NAME Manager, for example-
HS_FDS_SHAREABLE_NAME =/home/odbc64/unixODBC/2.3.1/lib/libodbc.so
Depending on where you install it.
Kind regards

Differences between ESXi and Vsphere hipervisor
Hi guys,.
I need to understand the difference between ESXI and Vsphere hipervisor.
Is it correct to say that Vsphere ESX?
Help will be very useful.
Thank you very much
vSphere is the range of products, including (hypervisor) ESX, vCenter (management) etc.
In comparison, you asked "Is this correct to say that a shoe laces"? No, not really. One is a part of the whole.

I have read and found some documents on ESXi.
According to the documents, I know that ESXi free version does not support some advanced virtual machine configurations and does not support write to ESXi host permission. But when I download ESXi from vmware.com, I can't find the free version. He will always be a trial of the licensed version edition because I can always do the configuration of start and stop virtual machines via vSphere Client installation. I can also run scripts (lamw) pl in vMA to stop the ESXi host (authorization to write ok?)
Then I confused. How can I get the really free version of ESXi? Or will the free version after 60 days of evaluation?
Start/stop above configuration is in vSphere Client via 'Configuration'-> "start/stop VM"-> "Properties"... «-> "Allow the virtual computers start and stop automatically with the system" actions setting and stop virtual machines can be configured to "comments"turn off computer"or"Suspend".» Can any body tell me if it's supported by ESXi free edition?
Is the free version of vSphere Client too? Because when I use the vSphere Client, he told me that I have 60 days of evaluation. This confused me again. I think that vSphere Client is always free, am I right?
Any suggestion or advice is much appreciated. _
Micky
Configuration of start and stop virtual machines is available with the free version and licensed, with the free version you would be configured everything via vSphere Client, where as with a licensed version, you can optionally use scripts to configure it and also issue restarts/stops using scripts.
Second, shutdownHostViaSOAPAPICall.pl for the version licensed and free of ESX (i), this script will work in both free and licensed because it uses direct SOAP calls emulating the vSphere Client communication. Take a look at the documentation for details, but this of course is not supported by VMware.

Network connections between VM and host is slow?
I have problems with the speed between the host and the VM, connections is limeted and very slow. I'll open the file and copy and it's slowly. My OS is VISTA Business and VM on XP SP3. Connection between VM card is limited to me and see that trafficking is not very practical. If this can be rectified and speed up the connection between the virtual machine and the host.
As I have written, you can use both at the same time. Just add a host connection only to the guest and make sure name resolution, host name (and the name of the client to the host) using the IP addresses assigned by DHCP VMWare Server for the host only (VMnet1, default) connection. The file "\system32\drivers\etc\hosts" ensures that this connection will be used, for example.

Connection between servers and opening default home
Question about cross-server logon, if a customer has changed their rules of routing so that the default value at the opening of "wishes" is no longer used and a different call handler is used instead, will be this connection between breaking servers? Looks like that connection between servers using backdoor functionality (# and some numbers) which works with the 'Opening of wishes' system, I understand this right?
No, it is not hardcoded to opening greeting Manager of appeal, but he needs to finish a greeting (whether for a Subscriber or call handler) - the logic is handled in the PHGreeting conversation (the guy that is used for the treatment of the call manager/subscriber wishes) - so if you have a routing rule that say, load the sign the Subscriber in conversation, then you're going to break.
But as long as the call is handled by _some_ greeting, the hand of logic should work because the conversation PHGreeting is looking for a specific series of TTS to indicate that it is a grip of calls.

Heterogeneous connection between Oracle and Postgres.
Hi all
I am trying to connect heterogeneous Postgres and Oracle for a few days, but I've always seen this error: "loss of the RPC connection.
First of all: I use Windows 7, Oracle 10 g and PostgreSQL 8.4.
I did the following:
(1) create a system DNS named "PG". (The connection test is OK)
(2) to create the file 'initPG.ora' in ' $ORACLE_HOME/hs/admin:
# This is an example of initialization file of the agent that contains the HS settings
# needed for an ODBC Agent.
#
# HS init parameters
#
HS_FDS_CONNECT_INFO = PG
HS_FDS_TRACE_LEVEL = WE
#
# Required for the non-Oracle system environment variables
#
#set < varenv > = < value >
(3) configure the file 'listener.ora' (in ' $ORACLE_HOME/NETWORK/ADMIN "):
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server)
(= Extproc PROGRAM)
)
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server)
(= Extproc PROGRAM)
)
(SID_DESC =
(SID_NAME = PG)
(ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server)
(PROGRAM = hsodbc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = CIP)(KEY = EXTPROC_FOR_XE))
(ADDRESS = (PROTOCOL = TCP) (HOST = Cédric-PC)(PORT = 1521))
)
)
DEFAULT_SERVICE_LISTENER = (XE)
(4) set up the 'tnsnames.ora' file (in ' $ORACLE_HOME/NETWORK/ADMIN "):
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = Cédric-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
)
)
PG =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = tcp) (HOST = Cédric-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = PG)
(HS = OK)
)
)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = CIP)(KEY = EXTPROC_FOR_XE))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = CIP)(KEY = EXTPROC_FOR_XE))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)
(5) Finally, I create my DB-Link and test it:
CREATE DATABASE LINK 'CENTRALE_POSTGRES' CONNECT TO 'user_login' IDENTIFIED BY 'user_password' USING "PG";
SELECT * FROM 'dual"@CENTRALE_POSTGRES;
I got this error:
ORA-03135: interruption of the RPC connection.
As you can see, I have activated the trace level (HS_FDS_TRACE_LEVEL = WE), but the still empty directory ' $ORACLE_HOME/NETWORK/trace.
Any ideas?
Concerningthe alias PG tnsnames.ora is wrong — you must have 2 closing brackets after the so that HS SERVICE_NAME = OK is outside the CONNECT_DATA as:
PG =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = tcp) (HOST = Cédric-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = PG))
(HS = OK)
) You should know also HSODBC to release 10.2 was desupported since March 2008 and it was replaced by its product follow-up DG4ODBC V11

JMS connection between glassfish and OSB
We are having architecture where between GlassFish and OSB JMS messages. I have the following questions of design
(1) what is the best way to send messages between these two App servers? (I mean use the JMS bridge or regularly use JNDI lookup and send the message and so on)? We want to send messages in both directions between these two App servers.
(2) how we use JNDI search inside glassfish for OSB. We use an approach by providing the full client jar fat weblogic. (53 MB) Is this the only way? Is there any thin weblogic client that we use for queue search OSB of glassfish?
Thanks in advance.Using a JMS client WL on GF has limits on XA/JTA, consuming messages from distributed locations and securing individual destinations. Workaround for the latter is to avoid to set ACLs on WL destinations and use SSL to encrypt network traffic if you wish.
I recommend the following general method: (1) avoid using WL JMS on the GF level clients if you need exactly once the e-mail or require the consumption of a distributed destination and (2) use OSB or WebLogic foreign seller JMS integration facilities for either (A) bridge/transfer messages between WL JMS and GF JMS or call (B) GF JMS directly the WL/OSB tier.
If you don't want to use a jar full of WebLogic as a customer, there is a pot of customer 'thin' t3 equivalent available in the latest version. I recommend the full jar unless a small pot size is an important condition in your use case. I recommend the thin 't3' jar on the thin "wl" pot as the pot thin t3 tends to have much better performance. Or the other of these clients can interact with older versions.
FAQ for vendors integrating a Remote JMS summarizes the Server WebLogic tools available for the integration of foreign suppliers (http://download.oracle.com/docs/cd/E14571_01/web.1111/e13727/interop.htm#JMSPG553). I'm not familiar with a tool equivalent/layers of OSB.
The stand-alone Clients documentation lists different JMS (http://download.oracle.com/docs/cd/E14571_01/web.1111/e13717/basics.htm#SACLT122) client options.
