Vhd has the sama function as virtual machine or hyper-v in windows 8

hi,
is VHD has the same function as hyper-v or virtual machine. if yes then I can make virtual machine from windows 7 home premium if the hardware support it.
thanks

All VHDs are Virtual Machines and have the same function since they emulate a hardware environment, but they are not compatible between the different VM software. They each have their own structure and are not directly compatible. There are utilities
that can be found on the internet that claim to export or import VMs from varies different VM software.
Windows 7 XP Mode and Virtual PC use the same structure, but Hyper-V is a different structure.

How to Install Hyper-V on a Virtual Machine in Hyper-V on windows 2erver 2012 R2 ?

Hi ,
anybody know How to Install Hyper-V on a Virtual Machine in Hyper-V on windows 2erver 2012 R2 ?
I want to create lab but i couldn't I follow this article but the new VM is off
http://blogs.technet.com/b/gbanin/archive/2013/06/26/how-to-install-hyper-v-on-a-virtual-machine-in-hyper-v.aspx
one of hyper-v component is not running
thanks

Previously it has been blocked to install Windows Server in the VM and then add the Hyper-V Role.
However, it has always been possible to install Hyper-V Server inside a VM. (the free Hyper-V Server SKU)
The Hyper-V Server VM is fully manageable, but it cannot start any VMs.

Can you create a FireFox add-on that has the same functionality as Momentum for Chrome?

Open a new tab that features a beautiful inspirational background photo.
Purpose is to keep you on task to achieve your goals - more than a to-do list.
"Good Morning, Afternoon or Evening <your name>"
Random motivational quote from a library which can be personally managed.
"Your goals or focus today is <whatever you input>"
Get a reward (music, a yipee!, or a new motivational quote) when you check off a completed goal.

Mozilla creates very, very few add-ons itself, you could probably count 'em on two hands. The vast majority are created by other users or independent developers.
You might want to post here - https://forums.addons.mozilla.org/ - or here - http://forums.mozillazine.org/viewforum.php?f=53 - with that request or ask the developer of Momentum if he would be willing to develop a similar add-on for Firefox.

Creative cloud applications won't open on additional machine - iMac 10.9.4 - Creative cloud for teams - a work colleague has the same issue on his home machine. Applications work fine at work.

These problems are happening on my iMac at home. I can log into Creative Cloud no problem, however as soon as I try and open an application, whether it's an old version or CC 2014, Adobe Application Manager opens and tells me that membership has expired and prompts me to 'try again'. Clicking this button results in a new pop up that thanks me and tells me that my subscription is now active. However as soon as I click 'continue' the process begins again, the application closes, a pop tells me that membership has expired etc.
I can login and view my Creative cloud for teams account online and everything seems to be in order and the applications open without incident at work, another colleague at my work has the same problem with his CC applications at home.
I've tried uninstalling and the installing all of the applications and CC several times, run all updates etc.
Is this an issue the the Terms and Conditions for CC2014, are we no longer allowed to run applications on 2 machines?
Is there a bug with the latex version of CC? This problems has only recently occurred.
I should add that I've read some of the other posts about login loops and I've tried deleting the opm.db file, it didn't work.
Thanks for any help anyone can provide.
Regards
Pete

There doesn't seem to be an uninstaller for CS3, and I've tried the CC Cleaner tool several times. It doesn't work and it is not correctly documented anywhere. For example, there is no log file at "/Users/[user name]/Adobe Creative Cloud Cleaner Tool.log" as one of the Adobe pages states. For example, there is no log file at "/Users/[user name]/Adobe Creative Cloud Cleaner Tool.log" so I can't find any success or error states of the tool.
There is a log file at "/Users/[me]/Library/Logs/ACC.log." Would there be anything in there that could shine light on install issues vs. uninstall issues?
Regardless, running Cleaner and then attempting to install ACC repeatedly leads to the error "Creative Cloud quit unexpectedly" upon launching it or rebooting (which launches it automatically). I've been trying various things for weeks to no avail yet.

This is : java.security
# This is the "master security properties file".
# In this file, various security properties are set for use by
# java.security classes. This is where users can statically register
# Cryptography Package Providers ("providers" for short). The term
# "provider" refers to a package or set of packages that supply a
# concrete implementation of a subset of the cryptography aspects of
# the Java Security API. A provider may, for example, implement one or
# more digital signature algorithms or message digest algorithms.
# Each provider must implement a subclass of the Provider class.
# To register a provider in this master security properties file,
# specify the Provider subclass name and priority in the format
# security.provider.<n>=<className>
# This declares a provider, and specifies its preference
# order n. The preference order is the order in which providers are
# searched for requested algorithms (when no specific provider is
# requested). The order is 1-based; 1 is the most preferred, followed
# by 2, and so on.
# <className> must specify the subclass of the Provider class whose
# constructor sets the values of various properties that are required
# for the Java Security API to look up the algorithms or other
# facilities implemented by the provider.
# There must be at least one provider specification in java.security.
# There is a default provider that comes standard with the JDK. It
# is called the "SUN" provider, and its Provider subclass
# named Sun appears in the sun.security.provider package. Thus, the
# "SUN" provider is registered via the following:
# security.provider.1=sun.security.provider.Sun
# (The number 1 is used for the default provider.)
# Note: Statically registered Provider subclasses are instantiated
# when the system is initialized. Providers can be dynamically
# registered instead by calls to either the addProvider or
# insertProviderAt method in the Security class.
# List of providers and their preference orders (see above):
security.provider.1=sun.security.provider.Sun
security.provider.2=sun.security.rsa.SunRsaSign
security.provider.3=com.sun.net.ssl.internal.ssl.Provider

# Properties to configure OCSP for certificate revocation checking
# Enable OCSP
# By default, OCSP is not used for certificate revocation checking.
# This property enables the use of OCSP when set to the value "true".
# NOTE: SocketPermission is required to connect to an OCSP responder.
# Example,
# ocsp.enable=true
# Location of the OCSP responder
# By default, the location of the OCSP responder is determined implicitly
# from the certificate being validated. This property explicitly specifies
# the location of the OCSP responder. The property is used when the
# Authority Information Access extension (defined in RFC 3280) is absent
# from the certificate or when it requires overriding.
# Example,
# ocsp.responderURL=http://ocsp.example.net:80
# Subject name of the OCSP responder's certificate
# By default, the certificate of the OCSP responder is that of the issuer
# of the certificate being validated. This property identifies the certificate
# of the OCSP responder when the default does not apply. Its value is a string
# distinguished name (defined in RFC 2253) which identifies a certificate in
# the set of certificates supplied during cert path validation. In cases where
# the subject name alone is not sufficient to uniquely identify the certificate
# then both the "ocsp.responderCertIssuerName" and
# "ocsp.responderCertSerialNumber" properties must be used instead. When this
# property is set then those two properties are ignored.
# Example,
# ocsp.responderCertSubjectName="CN=OCSP Responder, O=XYZ Corp"
# Issuer name of the OCSP responder's certificate
# By default, the certificate of the OCSP responder is that of the issuer
# of the certificate being validated. This property identifies the certificate
# of the OCSP responder when the default does not apply. Its value is a string
# distinguished name (defined in RFC 2253) which identifies a certificate in
# the set of certificates supplied during cert path validation. When this
# property is set then the "ocsp.responderCertSerialNumber" property must also
# be set. When the "ocsp.responderCertSubjectName" property is set then this
# property is ignored.
# Example,
# ocsp.responderCertIssuerName="CN=Enterprise CA, O=XYZ Corp"
# Serial number of the OCSP responder's certificate
# By default, the certificate of the OCSP responder is that of the issuer
# of the certificate being validated. This property identifies the certificate
# of the OCSP responder when the default does not apply. Its value is a string
# of hexadecimal digits (colon or space separators may be present) which
# identifies a certificate in the set of certificates supplied during cert path
# validation. When this property is set then the "ocsp.responderCertIssuerName"
# property must also be set. When the "ocsp.responderCertSubjectName" property
# is set then this property is ignored.
# Example,
# ocsp.responderCertSerialNumber=2A:FF:00

I am trying to installl Oracle 11gR2 on VM machine with Redhat Linux 6-64bit. That is a Oracle database problem. Even though the Oracle product uses java it still represents a problem with that product (Oracle) rather than java. So you need to start with an Oracle database forum.

Parallel run of the same function from multiple jobs

Hello, everyone!
I have a function which accepts a date range, reads invoices from a partitioned by date table and writes output to a partitioned by invoice table. Each invoice can have records only with one date, so both tables may have one invoice only in one partition, i.e. partitions do not overlap. Function commits after processing each date. The whole process was running about 6 hrs with 46 million records in source table.
We are expecting source table to grow over 150 million rows, so we decided to split it into 3 parallel jobs and each job will process 1/3 of dates, and, as a result, 1/3 of invoices.
So, we call this function from 3 concurrent UNIX jobs and each job passes its own range of dates.
What we noticed, is that even if we run 3 jobs concurrently, they do not run this way! When 1st job ends after 2 hrs of run, the number of commited rows in the target table is equal to the number of rows inserted by this job. When 2nd job ends after 4 hrs of run, the number of rows in the target table is equal the summary of two jobs. And the 3rd job ends only after 6 hrs.
So, instead of improving a process by splitting it into 3 parallel jobs we ended up having 3 jobs instead of one with the same 6 hrs until target table is loaded.
My question is - How to make it work? It looks like Oracle 11g is smart enough to recognize, that all 3 jobs are calling the same function and execute this function only once at the time. I.e. it looks like only one copy of the function is loaded into the memory at the same even if it called by 3 different sessions.
The function itself has a very complicated logic, does a lot of verifications by joining to another tables and we do not want to maintain 3 copies of the same code under different names. And beside this, the plan is that if with 150 mln rows we will have a performance problem, then split it to more concurrent jobs, for example 6 or 8 jobs. Obviously we do not want to maintain so many copies of the same code by copying this function into another names.
I was monitoring jobs by quering V$SESSION and V$SQLAREA ROWS_PROCESSED and EXECUTIONS and I can see, that each job has its own set of SID's (i.e. runs up to 8 parallel processes), but number of commited rows is always eqal to the number of rows from the 1st job, then 2nd+1st, etc. So, it looks like all processes of 2nd and 3rd jobs are waiting until 1st one is done.
Any ideas?

OK, this is my SQL and results (some output columns are ommited as irrelevant)

I have a database of names. When I go to the database and pull up names I right click on the option "Open in new tab". I would like to bring up 200 names and do the same function simultaaneously to them like, add a vote to their total individual vote count. Is this possible?

I ended up reformating the drive as FAT32 because I still need to use it on my Windows 98SE system also. I did have a problem with the allocation size. I wanted to use 512 bytes but it kept failing so I used the default size(8192 bytes) and then it worked fine. I didn't think there would be a problem formatting as NTFS but since you are having problems I just tried it. It failed at 512 bytes allocation size so I tried again using 4096 bytes, the default, as the allocation size and it failed again. It looks like these drives will not format as NTFS.
Also, I think I figured out what's going on with the ReadyBoost problem. As I said initially it wouldn't work with ReadyBoost then after I had 12GB of data on the drive the ReadyBoost feature started working. After I deleted all the files it quit working again. After doing some reading on the net about Flash drives and ReadyBoost problems it appears that the memory chips on my Lenovo Flash drive are mixed with both fast memory chips that work fine with ReadyBoost and slower memory chips that are too slow for ReadyBoost. Apparently, after I fill up the portion of memory with data that uses the slow chip(s) then ReadyBoost works fine with the fast chip(s). I also verified the Flash drives read and write memory speeds using Vista's Event Viewer. To work with ReadyBoost the Flash drive has to read at a minimum of 2.5MB/s (for 4KB random reads) and write at a minimum of 1.75MB/s (for 512KB random writes).
Let me know what you find out.

With out using Weblogic libraries to maintain the same functionality

Hi,
Please tell the solution of my problem.Here application developed in Weblogic,now we are migrating that applicationin jboss.Here one java servlet program is there which is using Weblogic libraries to get the connection pool .
How can change the code without using Weblogic libraries to maintain the same funtionality. Is there any alternate method to get the connection pools in Jboss.
Here I am attaching the code ,please go througth the code and provide me the correct solution.

Hi. There is nothing in even the most homicidal Java code
that can cause such an error. It is only native code that
can do it, and the two main suspects here are the JVM
itself or the OCI client libraries used by the Oracle driver
when connecting in the OCI/type-2 mode. Neither the
JVM author or Oracle will be lightly entrained in an effort
to debug it (C code is hard), unless you can provide a
small reliable reproducer program.
I highly recommend an alternative, that you switch to
using the driver in the all-Java/type-4/thin mode. It will
be much more reliable in this regard, and nowadays, the
thin driver can be toled to use the tnsnames.ora file for
connectivity info, so you can retain any administration
value/custom that uses those files.
Please say if there are any other reasons you can't do
that, and if so, the first steps would be to upgrade to the
latest OCI client and latest JVM, to see if the problem has
been fixed already.
Good Luck,

Help, my iphone 5 is locked and will not function! I've turned it off and on and it has the same fault. What ever you press on the screen highlights with a box round it. When you press the round button with the square in the centre the voice on the phone tells you the time. Then the voice says screen lock. If I try and unlock the phone the voice says phone unlock but you can't put the code in. If you hight the box it will say the number but not put the code in?! What's the crack?

Error has been detected by HotSpot Virtual Machine EXCEPTION_FLT_DIVIDE_BY_

Hi everyone,
i've got this error
# An unexpected error has been detected by HotSpot Virtual Machine:
# EXCEPTION_FLT_DIVIDE_BY_ZERO (0xc000008e) at pc=0x00bda829,
pid=1608, tid=1232
when i trying to use variables with type double or float.
for example:
public class AverageFruit {
public static void main(String[] args) {
// Declare and initialize three variables
double numOranges = 50.0E-1; // Initial value is 5.0
double numApples = 1.0E1; // Initial value is 10.0
double averageFruit = 0.0;
averageFruit = (numOranges + numApples)/2.0;
System.out.println("A totally fruity program");
System.out.println("Average fruit is " + averageFruit);
}

I don't see anything wrong with the code and I even compiled and ran it with 1.4.2_09 and got the following output:
> java AverageFruit
A totally fruity program
Average fruit is 7.5What JRE version are you using?

An unexpected error has been detected by HotSpot Virtual Machine: SIGBUS

We had a java server process shutdown with the following output:
# An unexpected error has been detected by HotSpot Virtual Machine:

Current thread (0x00000001001bc630): GCTaskThread [id=15]
Since then we've experienced a problem where the process has become unresponsive causing us to force a manual shutdown.
There was not an issue with available memory at the time the process became unresponsive. System.out stopped printing GC output at this time.
Hardware is a T5120.
Please let us know if there is a known issue or some way to resolve this.

Hey look, the VM crashed so i posted on a forum related to the VM.
If the hardware crashed I probably would have posted it on a forum related to the hardware.
If MS Word were to crash i probably would not start start blaming it on the hardware before I tried to find out if there is a problem with MS Word.
What I was hoping to find out was if there was some known issue with the particular version of the jdk or if there was some obvious cause....or possibly if there is something additional I could do to troubleshoot the problem. Specifically I said "Please let us know if there is a known issue or some way to resolve this."
Expanding on my previous replies.
There are any number of sources for the cause of the problem that the VM reported.
While it is possible that the VM itself caused it is also likely, probably quite a bit more so, that there is some other cause.
The causes of that can be hardware, OS, other applications and the software that the VM is running.
Resolution requires the following.
1. Identifying the cause
2. If and only if the cause is due to the VM then submitting a bug report.
3. Exclusive of a specific service/sales contract with Sun a bug fix is unlikely to be forthcoming in any reasonable amount of time.
So far all i've got out if this is that it's a hard problem to troubleshoot and there is a bunch more information necessary to determine the cause. Correct. If the VM created the dump file (whatever it is called) you can create a bug report and attach that. But 3 above still applies but sometimes Sun jumps right on something.
If that is the case then fine, i completely understand, but no one has said what additional information would be helpful. Your entire computer and a way to replicate it on that computer is the only way that any one besides you can determine that. And inclination and time.
I doubt that is acceptable to you nor is anyone likely to undertake that (exclusive of a specific commercial tie between you and Sun.)
The alternative is that you, or someone at your company, tracks the problem down. There are two many possible variations for how one might need to to that for a forum post and perhaps even for an entire book. But replicating it is the first step.
...unless you can provide some help or at least some useful information.You might want to google for SIGBUS and SIGSEGV error reports against the VM just to see how often this occurs.

JNI : Two native libraries with the same functions

Hello,
I have two versions of the same native library like "abc_v1.sl" and "abc_v2.sl".
They have the same functions but they act differently.
I want to use both of them in parallel (each in its own thread) but only the functions of the first loaded library are being called.
Isn't there any possibility to load each native library in a different name space... maybe a different JVM?
Any help will be appriciated.
Thank you!

Isn't there any possibility to load each native library in a different name space... maybe a different JVM?Naturally if you have different processes (different VMs) then each can load a different version.
This might actually be easier to do. Especially if you think that you are going to be adding more versions. It would require that you implement a communication api from each of thes to your main application.
If you want to do it in in a single process then you have some work to do in C. It has nothing to do with java or JNI.
Basically you need to dynamically load each library and the create a thunk to each method you want to access. Where 'thunk' represents a dynamic descriptor that allows you to dynamically call the method.
What you are doing now is statically loading the libraries. So that won't work.
You can search on your platform/compiler for examples on how to do that.
