Is the MySQL autoReconnect property used by default?
When specifying MySQL to be the OpenMQ JDBC store, will the [autoReconnect property|http://dev.mysql.com/doc/refman/5.0/en/connector-j-reference-configuration-properties.html] be set to true if this isn't specified in the configuration? I haven't set this property and have experienced that OpenMQ looses JDBC connection upon which it failed to operate again. I just want to rule out this as a possible reason.
------ Trond
The property that you point to belong to the JDBC driver not the broker. As far as I know OpenMQ does not set any properties on any of the JDBC driver to claims to support.

MySQL/JDBC. Use socket /tmp/mysql.sock NOT TCP/IP?
Does anybody know how to use the MySQL connector to use the file /tmp/mysql.sock to connect to MySQL locally? I can't find it in the docs. I currently don't have it running on any TCP/IP ports and figured there must be a way to use MySQL with Java without needing TCP/IP.
Cheers,
d11Because the .sock file isa unix domain socket. This is normally not available on other OS's. So, the sock is platform dependent, and Java, at least usually, does not support strictly platform dependent features, you can not use it (at least not using the standard API's). If you search, real hard, you may find some hacks to do so, but they are exactly that, hacks.

Hi,
I have created a custom field in SharePoint 2010. I have a xsl file which does the Xslt rendering for item display in list view. I need to add some C# code to the xslt code. So i included code as below:
1)
xml:user="urn::my-scripts" in the xsl:stylesheet tag.
2)
<msxsl:script language="C#" implements-prefix="user">
<msxsl:assembly name="System.Web"/>
<msxsl:using namespace="System.Web"/><![CDATA[public string GetDate(string DateFormat){return DateTime.Now.ToString(DateFormat);}]]>
</msxsl:script>
3) And used it in the code as
<xsl:value-of select="user:GetDate('dddd, dd MMMM yyyy')"/>
But, i get an error saying:
Execution of scripts was prohibited. Use the XsltSettings.EnableScript property to enable it. An error occurred at C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\template\layouts\xsl
Since its a custom field, i have only the XML file to declare the custom field and the XSLT to render it, when it comes to displaying in a list item view.
Though in some scenario's the XmlTransform class is used to set the XsltSettings.EnableScript
property through a C# code file, here it doesn't seem to be feasible.
Is there a way to set the EnableScript property in the XSLT or XML ? Or any other ways ?Hi Elena,
The issue is caused by XSLT is not script enabled by default. Please provide XsltSettings in the loading to fix the issue. For more information, please see:

Ignacio,
The excessive waits on log file parallel write and the related client wait of log file sync may be due to insufficient CPU availability, and may not point at an actual redo log size problem or a problem with the disk speed where the redo is written to disk, especially if there are 3 Oracle instances on the server with a single CPU.
Paraphrased from "Optimizing Oracle Performance":
The log file sync wait event is one of the first events to show increased latencies due to the time a process spends waiting in a CPU wait queue while processing excessive logical IOs.
Kevin Closson wrote a couple blog entries that examined the potential problems of insufficient CPU capacity and its effects on log file parallel write when writing to solid state disks, and even when writing redo was explicitly disabled:
http://kevinclosson.wordpress.com/2007/07/21/manly-men-only-use-solid-state-disk-for-redo-logging-lgwr-io-is-simple-but-not-lgwr-processing/
"Once LGWR loses his CPU it may be quite some time until he gets it back. For instance, if LGWR is preempted in the middle of trying to perform a redo buffer flush, there may be several time slices of execution for other processes before LGWR gets back on CPU..." Fix the CPU problem, and the other significant waits may decrease.
JesusLuvR,
yingkuan's suggestion to look at the SQL statement that performs the 4,365,564 logical IOs, consumes 186.03 CPU seconds, and has an execution time of 225.06 seconds, is likely a very good starting point. You might also want to check the value of the SESSION_CACHED_CURSORS parameter to see if it needs to be adjusted.

SharePoint Foundation 2013 -- How to add the document property option in default search template
Dear All
The search for foundation 2013 is working fine with me. I want to add the view document property in the search option? can any one tell me how can i do it in foundation 2013.
Here is a relevant post
http://www.abelsolutions.com/totm/creating-customized-search-results-in-sharepoint-2013/
I already done the followings:
1) Add the view property in Search Managed properties through central administration
2) I found one solution that shows me the .html files in SPD Catalog search template, that i did not found in the respective place. (there is no reason why its not there)
Can any one tell me how can i do that?

How can I get all the values of a String array profile property using javascript?
I am trying to build functionality into our site that records all products added to the basket against a user's profile.
I have so far been able to store the product codes against the profile as a property using Ajax:
var dataString = ":formid=addProduct&:formstart=/apps/thread/templates/page_product/jcr:content/par/produc t/formstart&:redirect=/content/thread/en/user/cart.html&productId=151515:profile="+profile ;
$.ajax({
type: "POST",
url: "/content/women/evening/dresses/l-k-bennett-davinadress.html",
data: dataString,
success: function(data) {
In this example I have hardcoded a product ID of 151515.
In order to save the property as a multi string field you simply replace &productId=151515 with &productId=151515&productId=131313&productId=141414 or as many extra values as you want to build into that string. This stores a productId property against a user profile.
The issue comes from calling that data back. Using var value = CQ_Analytics.ProfileDataMgr.getProperty("productId") I can get the first value of this array (or the single value if only one is stored).
However there does not seem to be a way to get any of the other stored values in the array using getProperty. Does anyone know how I can achieve this?Hi,
Don't think that's possible. Even if it were, you wouldn't be able to use/display BOOLEAN type in SQL.
If you just aim to see what they are, you could do something like this
select text
from all_source
where owner = 'SYS'
and name = 'DBMS_DB_VERSION'
and type = 'PACKAGE';Or even
select dbms_metadata.get_ddl('PACKAGE', 'DBMS_DB_VERSION', 'SYS') from dual;My version is:
SQL> select * from v$version where rownum = 1;

i have two apple id accounts ,when i used to update application it used to prompt a default id (the old one) and if the application was downloaded using the other id i would cancel and it would prompt the other id but not any more .
it just prompt the old id which im not signed in with im signed in using the new id and when i cancel nothing happens and when i try to update applications separately i have the same problem .
im signed in using the new id
the old one is my wife's so i can't delete it
the problem happens when i update all or each application by its own
using ios 5.0.1 on a iphone 3gs
the applications are downloaded using both the new and old id's
any help will be greatly appreciatedِThese are user-to-user forums, you are not talking to Apple here and they don't monitor these forums - I've asked the hosts to remove yout account ids from your post.
In terms of combining accounts it's not currently possible to do so, nor to copy/transfer content from account to another. -

Also when I tried to update my MYSQL connector / J driver to version 5.1.5 from 5.0.5 (NB 5.5.1) and 5.0.7 (NB 6.1), I could not get it work (looooong time to search some JDBC classes and with no response in the end) on both of my Netbean 5.5.1(on PC) and Netbean 6.1(on laptop) IDEs.
Could anybody look into this issue.
Many thanks

How do I use the Index Values property node with a multidimensional array.
I am using a 2D array to store operator inputs on my front panel. I only want to display one element to the operator at a time. I am trying to use the Index Values property node to change the displayed element. However, I can only get the Rows index to work. How do I direct the Columns index as well? The help says to use one per dimension. I need clarification on what this is talking about. I've tried adding a second element to the property node, 2 seperate property nodes, and diferent wiring techniques. (series, parallel)
If you only wire up one of the inputs (col or row) what you get out is a 1D array of either the column or row. If you wire controls to both, then you will get one element out of the array. Getting a single element in a 2D array requires you to specify both a row and column.

Can I use the 'Export Signal Property Node' on a quadrature encoder?
Hi,
So I don't know which counter board I'd be using yet for this (it's used in conjunction with a PCI-6280--the PCI-6280's counter inputs are all taken and so I need another board), but assuming this is possible at all in DAQmx I wouldn't mind knowing whether, say, the PCI-6601 (or any other timer board for that matter) could do this. I'm programming this in LabVIEW 2010 by the way.
I want to have a counter which counts the number of pulses on one channel (I'll call this the 'clock' channel) between when another channel goes from low to high (which I'll call the trigger). It's basically a pulse width measurement, but I only care if there are more than n clock pulses between triggers. I need to have a hardware-timed digital signal which goes from low to high if there are ever more than n pulses between trigger changing state from low to high.
What I am planning to do is this:
Wire 'trigger' to the z-input of the quadrature encoder, and set the z-input value to some arbitrary large value such that, at the quadrature encoder counter task's settings, the counter reaches terminal count in n pulses.
Configure the quadrature encoder counter using DAQmx Export Signal Property Node (tutorial I was looking at is here: http://zone.ni.com/devzone/cda/tut/p/id/5387 ) to toggle a digital channel ('counter event output') from low to high if the counter reaches terminal count (ie, if the encoder reads n pulses).
If the encoder ever reads n pulses on 'clock' between two rising pulses on 'trigger', it sets counter event output high.
Is this possible? Reading through the manual of M series PCI-62xx devices, the index pulse loads the counter with a particular value so it seems like you could conceivably set the counter to the terminal count if you wanted. My only real problem is whether DAQmx Export Signal Property Node works on all counter tasks or just on edge counting tasks.
Thanks in advance for your help. If this isn't possible, I can reply with more details on the problem this is supposed to solve so that you can help me figure out an alternate method.
Solved!
Go to Solution.There is probably a way to do it, but it it may be easier to use an X-series board for the job. They support a new counter capability for count reset on a digital edge without needing to be configured in encoder position mode. I am not sure exactly how that feature's been implemented however, so maybe it won't make things easier after all.
The plan based on the hoped-for behavior:
1. Configure an X-series counter for pulse generation based on "ticks" of your clock channel.
2. Set both initial delay and low time to the critical # of ticks.
3. Configure for count reset on a digital edge (if possible in pulse generation mode)
4. Configure the count reset value to be the critical # (or possibly 1 less, if possible in pulse generation mode)
5. If you want the output to remain high indefinitely, configure the counter task to use its own output as a
pause trigger, and pause while high.
The way pulse generation works is to preload a # of "low time" ticks into the count register. Then every source edge will decrement the count. When the count reaches terminal count (0), the counter's output is toggled (or can be configured to pulse). The register is then loaded with the # of "high time" ticks and the process continues.
You would be perpetually interrupting the count-down process as long as you got your triggers in time. The count would keep getting reset to the # of low counts, keep decrementing toward 0 without reaching it, and so on. If ever you did reach 0, the output state would toggle high, then the high state would prevent subsequent clock signals from decrementing the count.
You can conceivably do a similar thing with a 6601, but I'm pretty sure you'd need 2 counters working together to get it working.

Hi
Here is the situation:
I have a Farm with 3 servers W2012R2 in a Domain
Server1 Server 2
Server3
RDSession Host RDSession Host
RDSession Host
Connection Broker Connection Broker (Passive)
RD Web Access
2 DNS Alias : - poc.mydomain.local (Use for the RD Web Access and points to Server1
-poccb.mydomain.local (Use for the Connection Broker and points to Server1)
I have setup the Connection broker in HA with Server2 as Passive Server : DNS Round Robin poccb.mydomain.local (Server1)
The certificate Manager has generated 2 CA certificates :
- 1 for the RD Web Acc (poc.mydomain.local
-1 for Connection Broker SSO and for publishing
I have created 1 Group Policy for these 3 servers and 1 GP for my client Windows 7 SP1.
Server GPO :
Computer/Administrative Templates/Windows Components/Remote Desktop Services/Remote Desktop Session Host/Security
Always prompt for password upon connection=Disabled
Require use of specific security layer for remote (RDP) connections : SSL (TLS 1.0)
Set client connection encryption level : High Level
Client GPO
Computer/Administrative Templates/System/Credentials Delegation = Allow delegating default credentials (Concatenate OS defaults with input above)
TERMSRV/POCCB.mydomain.local
I use no Gateway and in my collection,I have activated SSL (Like in my Server GPO)
I have now problem with SSO.
Connection with remote desktop client with server name = poccb.mydomain.local
Your system administrator does not allow you the use of default credentials to log on to the remote computer poccb.mydomain.local because its identity is not fully verified
If in my client GPO I add the physical name of the 3 servers, it works :
TERMSRV/Server1
TERMSRV/Server2
TERMSRV/Server3
Open RDP Files with server name = poccb.mydomain.local
if my connection broker connects me on Server1 , no problem
But If I arrive on Server2 & Server 3=
Your system administrator does not allow the use of default credentials to log on to Work Resources
I have searched on internet. No result for " to log on to Work Resources"
Any idea ? Thanks for your helpHi,
Thank you for posting in Windows Server Forum.
Firstly check that, your user is using domain\username to enter the credential in the dialog box.
Now for a try, you can edit .rdp file with notepad and just place “enablecredsspsupport:i:0” line in it, save it an launch to check whether you are facing same issue.
As you are using windows 7 then upgrade to RDP 8.1. Also as you have already enter the FQDN name of server under “Allow delegating default credentials”. For a try please enable and configure for all the remaining settings as follow and check the result.
Start / Run / gpedit.msc / Computer Configuration / Administrative Templates / System / Credentials Delegation, and make sure you have the following four options enabled and configured:
Allow Delegating Default Credentials with NTLM-only Server Authentication
Allow Delegating Default Credentials
Allow Delegating Saved Credentials
Allow Delegating Saved Credentials with NTLM-only Server Authentication
Finally, open a command prompt and use “gpupdate /force” command to apply the policy directly.
More information:
Remote desktop credentials did not work
Hope it helps!
Thanks.
