Need to delete local references in the context of unknown call
HelloI was looking for the need to remove local references and came across this documentation,
That means the calling context unknown? and how it causes no local references to remain allocated in the reference table that returns the native function?
http://Java.Sun.com/docs/books/JNI/HTML/refs.html
5.2.1 releasing local references
You want to write a utility function that is called from unfamiliar contexts. MyNewString in Section 4.3 example illustrates the use of Delete-LocalRef to remove local references promptly in a utility function. Otherwise, there will be two local references that remains allocated after each call to the function MyNewString.
How does it cause local references to remain allocated in the reference table that returns the native function?
Because it does not refer to the JVM when it gets released, he returned to the context of unknown number, i.e. an another piece of native code in your JNI layer. If the references remain until the unknown caller's context returns to the JVM.

Needs inventory of local network VIRTUAL the virtual computer for each network adapter
Hello
I'm looking for VLAN VM inventories for each network adapter, the script lists the following details at the exit of the CSV file.
VMname | Cluster name | Name NIC-1 | Name of VLAN. NIC name-2 | Name of VLAN.
Thanks in advance!Hello
$(gkulikowski #08: 15:06 > get-vm | %{$clustername = ($_ | get-cluster) .name; $_ |}) Get-NetworkAdapter | Select @{N = "Name VM"; E={$_. Parent}},@{N='Cluster'; E={$ClusterName}},NetworkName,@{N='NetworkCard'; E={$_. Name}}}). Export-csv-path c:\out.csv
but it will be output that
Name of the computer Virtual Cluster NetworkName card
------- ------- ----------- -----------So if you have more than 2 NICs for you will see them as well. not in the form of columns but as rows.
OK, and if you want to have in the columns, I wrote like this:
$(get-vm testgk | %{$clustername = ($_ | get-cluster) .name; $ntwkcards = $_______ |}) Get-NetworkAdapter; » » | Select @{N = "Name VM"; E = {$ntwkcards [0].} Parent}}, @{N = "Cluster"; E={$ClusterName}},@{N='NetworkCard 0'; E = {$ntwkcards [0].} VLAN Name}},@{N='NetworkCard 0'; E = {$ntwkcards [0].} NetworkName}},@{N='NetworkCard 1'; E = {$ntwkcards [1].} Name}},@{N='NetworkCard 1 vlan'; E = {$ntwkcards [1].} NetworkName}}}). Export-Csv c:\out-file.csv
It will be the exact release you requested.
'Virtual machine name', 'Cluster', 'Map' 0 '', 'Card 0 vlan' map 1 ","map 1 vlan.
You mentioned the name of vlan, so I guess that you think of the name of portgroup.

I bought a new computer. When I try to send an e-mail to multiple recipients, now, I get this message: "there are non-ASCII characters in the local part of the address of the recipient. It is not yet supported. If please change this address and try again. "I don't know what are the non-ASCII characters, so I don't know what to do. I never had this problem on my old computer. Please explain in simple language.
The 'local' part in the context of email addresses, the part to the left of the symbol @. The warning is a bit of a surprise, because in general the owner of a mail server is relatively free to specify the address format. There is a movement to allow the games to other characters to be used in the fields, so I'm a little disappointed to see that, apparently, e-mail does not support the latter in the local part yet or it can be your SMTP server that generates this message.
ASCII characters ("American Standard Code for Information Interchange") are, on the whole, the English alphabet, uppercase and lowercase, as well as figures, common punctuation and case of things like the asterisks, obliques and media bars, but not of accented characters. But even apparently simple things like spaces and dashes have cousins who, at first glance, appear to be identical, but are not represented in the ASCII system. I am thinking especially nonbreaking spaces, dash and half-quadratin.
But I don't know why your new computer must have caused these warnings.

Do I have to close the 'context of the sequence' in Labview?
Hello
I pass the Teststand SequenceContext for Labview to access step.
Now my question is: do I have to close the past SequenceContext-reference mentioning 'close' in Labview?
Or this reference is automatically closed?
Is it possible that the closure is NOT the reference takes memory?
Thx for the help
Hi OnlyOne,
Any reference TestStand that you pass to your code as an input module will be automatically closed/released/managed by TestStand so you don't have to worry about the reference to the context of the sequence of your VI of closing.

Original title: Registery Error Message
During startup, I get an error message that the registry database cannot find a file and modify registry to delete the reference to the file in the registry. How can I do this?
Hello
- What were the changes made before the problem occurred?
I recommend you perform the clean boot.
Configuration of your system in a clean boot state helps determine if third-party applications or startup items are causing the problem. If so, you need to maybe contact the manufacturer of the program for updates or uninstall and reinstall the program.
See the following article in the Microsoft KB for more information on how to solve a problem by performing a clean boot in Windows Vista or Windows 7:
How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

Note: After troubleshooting, be sure to set the computer to start as usual as mentioned in step 7 in the above article. -

Thanks in advance...Hello
Signature of the procedure is
CREATE OR REPLACE PROCEDURE DWARE.P_CSCV_AGR_MONTH_REVENUE ( TBL_NAME VARCHAR2, START_DATE DATE, RESULT_ OUT NUMBER )
either he's expecting two input parameters, tbl_name in VARCHAR2 and the other START_DATE date format format. Also you need a variable with the number data type to store the value of the PARAMETER RESULT_
Now, look at the way you call this procedure
BEGIN DWARE.P_CSCV_AGR_MONTH_REVENUE(CSCV_AGR_MONTH_REVENUE,'01/01/2010'); END; /
first parameter must be a VARCHAR2, so place CSCV_AGR_MONTH_REVENUE in single quotes.
second parameter must be a date, so use to_date() function.
Finally declare a variable with the data type of number to maintain the value of the parameter RESULT_Something like this:
declare t_num number; begin a('CSCV_AGR_MONTH_REVENUE',to_date('01/01/2010','MM/DD/YYYY'),t_num); dbms_output.put_line(t_num); end;

I'm selling my laptop, but before I can I need to delete all of my friends out of it. I realized how do it, but now my computer won't turn on. I bought a new battery and a new charger, but the charger does not work, and now I've lost the old one.
Does anyone have advice? I tried out the battery and now the power for 30 seconds button. Nothing happened.
Hi jkeppl1,
You have not provided the model of your laptop, but I guess it is old enough. The general approach in this situation would be to remove the hard drive, put it in an external hard drive enclosure, plug this case into the USB port on another PC and run your utility. Since the laptop does, however, my suggestion would be to simply sell without a hard drive, since even a plu working laptop won't be worth much more that $50 any way, much less one that won't turn on.
I recently got an Inspiron N5010 without hard drive that wasn't turn on for free. I have solved the problem, install a hard drive $ 15, installed Windows 7 and gave it to a family member. The thing works beautifully.

Conversion of a delete using the context statement and policies MEV
Hello
I'm trying to convert a delete statement in an update statement using the context and political MEV.

I found the following way: I create a policy to avoid the physical deletion. In addition, the political function should update the deletion indicator too.

When I try to delete a record from the table test_a:

No row has been deleted, but the update stmt does not work. This means that the 'deleted' flag has not been updated.
Any ideas?
Thank you in advance.

Published by: albrotar on October 15, 2012 08:43The policy function is applied once per execution of the statement. The political function executes first, and the UPDATE statement updates probably, no line because the context is not yet filled. The level of the line fills the frame (I'm assuming that your session may even see context values populated by autonomous transaction - I guess it's possible, but I have to test this) after the UPDATE statement is already complete. VALIDATION in the row-level trigger is also useless - it does that to changes made by the current transaction that is independent, of which there is none--it cannot apply to changes made in the other autonomous transactions. Declaring the level line trigger to use autonomous transactions does not seem to do anything other than to open the question of whether the values defined under the autonomous transaction are visible in the transactions of the appellant.
Even if, somehow, did not work, the use of transactions autonomous would be a very bad idea because Oracle is free to roll back a partially executed query (and the work done by its triggers) and re - run. Oracle does with some regularity to maintain the consistency of Scripture.
