WMI query hanging

I have some code (VB Script) that is collecting CPU performance metrics from WMI. The code works well on all of the servers (identical servers) but after a period of time (8 hours, 30 hours, other random times) on some of the servers the query hangs.
After several hours (e.g. 8 hours) the query will work again on the server. I have used WBEMTEST to query the CIMv2 namespace to perform the same query on the server where WMI is having a problem and it also hangs.
The query eventually times out and does not return a value.
I have asked the team to rebuild WMI and after they completed the rebuild, the problem still occurs.
Since the code is only performing a read operation on WMI, I do not see how the query can cause the hang of WMI.
Any ideas on what I should do next?
Thanks

Hi,
Before going further, would you please let me know whether install all
necessary Windows Updates on those servers?

When the
hang issue occurred, please check if consume high RAM or CPU. Just a confirmation, thanks for your understanding.
In addition, please use the WMI Diagnosis Utility and check if can help you to analyze this issue. for more

SCCM 2012 R2 CU2 Can't Edit WMI Query Code in Report Builder

I first posted this in the SCCM but the issue is not solved so I thought I'd try here in the SQL Reporting forum. Original thread here: http://social.technet.microsoft.com/Forums/en-US/b0a6ca3d-7471-4b49-8447-7403a65c2ec0/sccm-2012-r2-cu2-cant-edit-wmi-query-code-in-sccm-reports?forum=configmanagergeneral
I'll repost info here to make this easier.....
I built a new SCCM 2012 R2 CU2 suite on Server 2012 R2. This also uses SQL 2012 SP1 CU6. This suite has 4 servers: site server, two for WSUS and secondary DPs, and SQL. This problem is true for the built in reports and my custom reports. Our SQL guy has
been helping me a lot but we've gotten nowhere. I can run a report. I can open one in edit mode after it prompts me for credentials. It loads Report Builder 3.0. But when I go to a dataset/query, enter credentials, and try to open it, I get a popup that
says "Unable to connect to data source. 'AutoGen_5C6358F2_yayak..." When I click on details it says "The target principal name is incorrect. A connection was succesfully established with the server, but then an error occurred during the login
process. (SSL Provider, error: 0 -The target principal name is incorrect.)" In SQL Reporting Services Config Manager the paths for Web Service URL is
http://ip.ip.ip.ip:80/ReportServer_SC01 and for Report Manager URL:
http://ip.ip.ip.ip:80/Reports_SC01. A domain account is used to login. This happens when you r-click a dataset and select query to edit the code of a dataset, ie, when query designer tries to open up. It happens
in both Admin Console and when using the Report Manager URL within SQL SSRS. All other functions of using edit mode of a report work fine.

When I do that, browse is dimmed out.
But, if I deselect "create a data set" and click "choose an existing dataset in this report..." there is no data connection at the end.
But if I don't use report builder and instead use IE to browse to my ConfigMgr_ABC, I do see the connection at the end: {123...}.
This problem is on a network that is not on the 'net, so it's hard to do screen shots, so I'll reproduce this problem step by step:
I pick a report to edit, it doesn't matter which one.
If I try it in Admin Console, I right-click, Edit the report, it asks me for a login, I login, then I get a popup that says "Cannot continue. The application is improperly formatted. Contact the vendor for assistance. I click the Details button and
get a long set of text but the key part is "Your web browser settings do not allow you to run signed applications." This msg didn't appear before, so something changed, so I will investigate. I think it used to give a SPN error.
If I use IE within report builder and navigate to whatever report, click open, everything works, except, when I click on Dataset0 (the key one I normally need to edit), click query, it prompts me for a login and no matter which one I use, i get a popup that
says "unable to connect to data source 'AutoGen_123...'". If I click details I get "the targe principal name is incorrect. A connection was successfully established with the server, but then an error occurred during the login process. (provider:
SSL Provider 0-The target principal name is incorrect.)

Operations manager failed to run a wmi query for wmi events (0x800706ba)

Hi everyone,
I've been working on this issue for a while and I am still no closer to finding out what the problem is. If anybody can offer any other advice or things to check, I'm all ears.
I'm running SCOM 2012 R2 with UR2, and the Cluster Management Pack v6.0.7063.0
My problem is on one particular batch of cluster servers where I am getting the following error.
Name: Operations Manager failed to run a WMI query for WMI events
Alert Description:
Module was unable to enumerate the WMI data
Error: 0x800706ba
Details: The RPC server is unavailable
Workflow name: Microsoft.Windows.Cluster.Node.StateMonitoring
Instance Name: servername.domain.local
Instance ID: {instance_id}
Management group: SCOM_Management_Grp_Name
I am getting this alert regardless of whether I run the Windows Cluster Action Account as Local System, or as a domain user with full local admin privileges on all the cluster nodes.
When looking at the management pack and the workflow in particular (Microsoft.Windows.Cluster.Node.StateMonitoring), I can see that it's trying to access
MSCluster_Node in the root\MSCLUSTER WMI namespace.
This is the workflow for your information...

I can confirm that I am able to browse the MSCluster_Node class locally, as well as remotely using WMIEXPLORER and WBEMTEST,
however it only works when I set the Authentication Level to
Packet Privacy. If I do not select Packet Privacy, a WMI event log error 5605 is logged on the remote servers application log that says...
The root\mscluster namespace is marked with the RequiresEncryption flag. Access to this namespace might be denied if the script or application does not have the appropriate authentication level. Change the authentication level to Pkt_Privacy
and run the script or application again.
I can confirm that all firewalls are turned off, and there are no firewalls between the management servers and the agents in question. AV exclusions have been done and appear to be in place. The nodes are all Windows 2008 R2 with SP1. As
far as I can tell there is plenty of memory available on each of the nodes in question (50%+) of RAM is available.
If I manually run the "Discover the Windows Server 2008 R2 Cluster Components" task in the Cluster Service State section of the management pack in the Monitoring Pane in the console, on the nodes in question - the discovery runs successfully.
Does anybody have any other ideas or suggestions I could try?
Many thanks in advance,
Noel.

Loop with WMI Query taking too long, need to break out if time exceeds 5 min

I've written a script that will loop through a list of computers and run a WMI query using the Win32_Product class. I am pinging the host first to ensure its online which eliminates wasting time but the issue I'm facing is that some of the machines
are online but the WMI Query takes too long and holds up the script. I wanted to add a timeout to the WMI query so if a particular host will not respond to the query or gets stuck the loop will break out an go to the next computer object. I've added my code
below:
$Computers = @()
$computers += "BES10-BH"
$computers += "AUTSUP-VSUS"
$computers += "AppClus06-BH"
$computers += "Aut01-BH"
$computers += "AutLH-VSUS"
$computers += "AW-MGMT01-VSUS"
$computers += "BAMBOOAGT-VSUS"
## Loop through all computer objects found in $Computes Array
$JavaInfo = @()
FOREACH($Client in $Computers)
## Gather WMI installed Software info from each client queried
Clear-Host
Write-Host "Querying: $Client" -foregroundcolor "yellow"
$HostCount++
$Online = (test-connection -ComputerName ADRAP-VSUS -Count 1 -Quiet)
IF($Online -eq "True")
$ColItem = Get-WmiObject -Class Win32_Product -ComputerName $Client -ErrorAction SilentlyContinue | `
Where {(($_.name -match "Java") -and (!($_.name -match "Auto|Visual")))} | `
Select-Object Name,Version
FOREACH($Item in $ColItem)
## Write Host Name as variable
$HostNm = ($Client).ToUpper()
## Query Named Version of Java, if Java is not installed fill variable as "No Java Installed
$JavaVerName = $Item.name
IF([string]::IsNullOrEmpty($JavaVerName))
{$JavaVerName = "No Installed"}
## Query Version of Java, if Java is not installed fill variable as "No Java Installed
$JavaVer = $Item.Version
IF([string]::IsNullOrEmpty($JavaVer))
{$JavaVer = "Not Installed"}
## Create new object to organize Host,JavaName & Version
$JavaProp = New-Object -TypeName PSObject -Property @{
"HostName" = $HostNm
"JavaVerName" = $JavaVerName
"JavaVer" = $JavaVer
## Add new object data "JavaProp" from loop into array "JavaInfo"
$JavaInfo += $JavaProp
Else
{Write-Host "$Client didn't respond, Skipping..." -foregroundcolor "Red"}

Let me give you a bigger picture of the script. I've included the emailed table the script produces and the actual script. While running the script certain hosts get hung up when running the WMI query which causes the script to never complete. From one of
the posts I was able to use the Get-WmiCustom function to add a timeout 0f 15 seconds and then the script will continue if it is stuck. The problem is when a host is skipped I am not aware of it because my script is not reporting the server that timed out.
If you look at ZLBH02-VSUS highlighted in the report you can see that its reporting not installed when it should say something to the effect query hung.
How can I add a variable in the function that will be available outside the function that I can key off of to differentiate between a host that does not have the software installed and one that failed to query?

Using environment variables in a wmi query

Hello
I'm trying to use WMI Queries on Group Policy Preferences to targeting computers on my network.
I have a file named testfile.txt in Windows directory and I check its last modified date to replace the policy files if the date is older of than current file.
I set this query : Select * from CIM_DataFile where Name='C:\\Windows\\testfile.txt' and LastModified<'20140910145110.821214+180'.
The replace action occurs on all machines where windows directory is 'C:\Windows\'. But there are machines on network where windows is installed on directory 'C:\Windows7'.
So I was thinking to use %WindowsDir% environment variable in the WMI query to ckeck testfile.txt date on the correct directory where windows is installed.
I've tried different ways to use this environment variable in WMI query with no success (For example: Select * from CIM_DataFile where Name='%WindowsDir%\\testfile.txt' and LastModified<'20140910145110.821214+180').
Can someone help me with the correct syntax?
Thanks.

Short answer: You cannot use environment variables in WMI filters.
But you can modify your query:
Select * from CIM_DataFile where (Name = 'C:\\Windows\\testfile.txt' or
Name = 'C:\\Windows7\\testfile.txt' ) and
LastModified<'20140910145110.821214+180'
Event this one should work:
Select * from CIM_DataFile where Name like 'C:\\Windows%\\testfile.txt'
and LastModified<'20140910145110.821214+180'
BTW: The variable should be %windir% anyway, not %windowsdir% :)

Oracle 9.2.0.6; query hangs if partition doesn't exist

Hallo all,
this is the first time I post on this forum.
I work in a group of PL\SQL developers in Italy. Few day ago we had a problem with a query and like to find out what the problem is.
We have an Oracle DB version 9.2.0.6 (old I know) in a production environment. Linux OS.
The query was made to extract data from a partitined table, on a partioned field, in our casa one Year. By mistake we have serced for the wrong year, 2013. There where no data for that year and therefor no partition.
So, happened that the query hangs and after 24 hours was terminated.
What we expected indeed was a zero records retirned in, at the most, few minutes, see that the table, in severa partition contains about 16 million records.
The we tested the same query but in a different enviroment, Oracle 11gr2, same table structure, same partitioning, without partition 2013, and the query completed in less tha 1 minute with zero records in output.
At this point we thought of a bug, but can't find any reference.
Has anyone had a similar experience or can give some indication of possible bug report.
Thanks for any help.

Hi Rob,
thank you for your answer.
Sorry if this is not the best forum. I am not very practical.
I try to answer to your questions.
At a first time we thought the query did a full scan on the table. Yes. But even to full scan 16.000.000 records split in no more than 8 partition (at this time) shouldn't take up to 24 hours and never stop running. I think.
We don't have a DBA role so we do not have full control over what is running. And take too long time to open a ticket and ask the DBA to check.
What we did is testing the same query in a pre-prod environment, which is an Oracle 11gr2.
I understand that it is not very usual to have a pre-production environment with a latest version of oracle but this is the way we have to work.
Anyway, the test in pre-production worked very well. Without 2013 partition the return was very fast and we had zero records as expected.
Then we found a workaround for production, ora 9. Call it work around maybe is too much ........
We created the 2013 partition and run the query. The respons was then succesfull in about the same time than in pre-prod. Less than one minute and zero records.
And this is fine for us.
What we don't understand is why this different behavior with two different version of DB. Thats why we think it is due to a bug. We only want to find out whether it is this or if there is a different reason.
Some other response or help would help.
Thank you.

Sql query hangs close to the end

Hi:
I am on 10.2.0.3.
My rather simple query hangs for a few minutes close to the end. It's supposed to return 288 rows and it immediately returns 285, then hangs for 4-5 min, than returns the remaining 3 rows. Kind of similar behavior to using "First_rows" hint - which I'm not using...
The table has about 100,000 rows.
Some relevant info is below.
Any ides appreciated.
TIA

You said the query is supposed to return 288 rows, but from the explain plan, Oracle "see" only 1 row to be returned. Are the stats up-to-date ? What's the actual query ?
Please, on the forum side, use tags before and after your code to keep it readable (preserve blanks and tabs).

Query hangs on Value Help

Hi,
We have created a query in which we are using quantity conversion ( defined in RSUOM ) , the target quantity is to be taken from a variable. The quantity conversions is running fine but when we do a value help for the target quantity variable in Portal, the query hangs. We are not facing any such issue in Bex Analyzer.
Please share your ideas on what could be the possible reason for this.
Thanks and Regards,
Manish Sharma

Hello Manish,
This is clearly a Portal issue.
Probably an issue with BI Java.
I recommend you to update your BI Java components to latest patch recommended by Java SP_Patch Matrix.
If you are using Netweaver 7.0, please check the link below:
http://www.sdn.sap.com/irj/sdn/index?rid=/webcontent/uuid/6010addf-e096-2b10-8893-e98586d005f9 [original link is broken]
If you are using Netweaver 7.0 EHP 1 (7.01), please the this link:

Applying the patches recommended should solve the issue.
Also, as a recommendation, run the BI Diagnostics - note 937697 - and correct the red alerts.

SCCM 2012 R2 Report using WMI Query

I am trying to find out if I can generate a report to show which users installed what software using a report in SCCM 2012 R2 and a WMI Query.
If not using the reporting within SCCM, then:
1) is it possible to pull such data via a wmi query
2) any suggestions how to do so?
3) Desktop OS is either Windows 7 or 8 or 8.1 Enterprise x64
Thanks,
Dave
David Lakey

You Can Create Query With the Software name but you can Know Which Computer and you can add System Resource as the Last login name
This for Example:-
From monitoring--> Create New Query--> Edit Query Statement --> Show Query Language
past the following:-
select SMS_R_System.NetbiosName,
SMS_G_System_ADD_REMOVE_PROGRAMS.DisplayName from
SMS_R_System inner join SMS_G_System_ADD_REMOVE_PROGRAMS on
SMS_G_System_ADD_REMOVE_PROGRAMS.ResourceId =
SMS_R_System.ResourceId where
SMS_G_System_ADD_REMOVE_PROGRAMS.DisplayName like "%Visio%"
After that in General you can add in Results Tap:-
System Source and the Attribute Will be last Login name

Query hangs on 2.4 release

I was migrating the code from 2.3 to 2.4 and tested the query with a fairly large expression, the query hangs:
my test query is this:
"collection('people.dbxml')/people/person[name=$name and (@id!=655 and @id!=660 and @id!=659 and @id!=664 and @id!=663 and @id!=655 and @id!=660 and @id!=663 and @id!=661 and @id!=662 and @id!=657 and @id!=691 and @id!=689 and @id!=692 and @id!=658 and @id!=689 and @id!=654 and @id!=688)]";
that worked on 2.3, anyone has a solution??

The query optimizer in DB XML 2.4 has had a big overhaul, and it's now performing a lot more optimizations than the previous version used to. I've found and fixed your bug now, and it should be being released as a patch soon.
Please detail any suspected bugs in a thread on the forums - one of the DB XML developers will work with you to find and resolve your problems.
Jhon, your problems seem to be quite different to the one in this thread.

Query Hangs while Parsing

In one of our databases, one of the Select query hangs at the parsing stage. The query was working fine few days back. How and what can be traced to see the cause of this hang. Database is in 10.2.0.3 and statistics has been gathered for all the affected tables.

Thanks for the info. The SEQ# is not changing in the v$session_waits. I have found a workaround for this problem. If I delete the statistics for CS_MEASUREMENT table, the query gets executed in .35 secs! If i collect stats again and runs, it hangs.
The session trace below.

Join Query hanging

hi experts,
please help on this, we have migrated database from 10g to 11.2.0.3 , Everything went sccessful but one of the simple join query hanging occasionally in new upgraded database. is there any known issue or anything need to add after migration for sqls?,also before migration its was executed without any issues. that query is joining and fetching from two more tables . is there any generic reason please provide that would be helpful to analyze, Thanks in Advance.

why wasn't this discovered during testing prior to the upgrade?
does new DB have current statistics?
How do I ask a question on the forums?

Query hangs with outer query

Hi,
OS: SPARC 64 bit

My query hangs when I include the outer query. When I execute without outer query It comes out in a fraction of second but when I includes outer query it starts hang

but when I includes outer query I hangs it is really very weird for me?
Here is the explain plan for that query
Execution Plan

Predicate Information (identified by operation id):
1 - filter("RAW_RNUM_">0)
2 - filter(ROWNUM<=10000)
5 - filter("DAY_OF_YEAR"=99 AND "TIME_STAMP">=TO_DATE('2009-04-08 00:00:00', 'yyyy-mm-dd hh24:mi:ss') AND
"TIME_STAMP"<=TO_DATE('2009-04-09 00:00:00', 'yyyy-mm-dd hh24:mi:ss') AND ("NETWORK_ID"=1025 OR
"NETWORK_ID"=1026))
7 - access("INTERFACE"='TRAFIC')
can one explain why it happen? what could be the reason? Is it a bug or something? what should I do now? Issue is critical in the production enviromentent
Waiting for your Valuable Reply
Thanks In Advance

I suspect the issue with the where clause (raw_rnum_ > 0)
Actually I using bitmap index on ' INTERFACE' column. Does it causing a prob or raw_rnum_ causing a problem?Boo,
a couple of comments:
1. Why do you use the deprecated FIRST_ROWS hint? From 9i on the FIRST_ROWS_n mode should be used instead, and since you're using a top-N query format the hint should be superfluous anyway since the optimizer should switch to FIRST_ROWS_n mode automatically.
2. Why do you use a BITMAP index and not a conventional b*tree index? Let me hazard a guess: Because the INTERFACE column has a small number of distinct values? That would be in most cases a bad idea.
3. What seems to be odd that you're accessing the data via the BITMAP index on INTERFACE, but request an ORDER BY ID DESC. But there is no order by in the execution plan posted. I wonder where the order should come from? Can you show us the DDL of the bitmap index?
4. What does the plan look like if you run only the inner query without the outer query?
You can always gain more information by tracing the statement execution or using the GATHER_PLAN_STATISTICS hint together with the DBMS_XPLAN.DISPLAY_CURSOR function.

WMI Query to retrieve only active IPv4 address

My turn to ask a question. I am running BGInfo for all workstations but at this stage want to only return the Active IPv4 address. I have a custom WMI query set up in BGInfo:
SELECT IPAddress FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = 'True'
This will return both IPv4 and v6 addresses. Without disabling IPv6 on my client workstations, is there a way I can get the query to return only the IPv4 address? Or should I instead create a custom vbscript in BGInfo to get the v4 address.
Cheers
Jeremy

You'd need to nose through the results and reject any IPv6 addresses.
This sample assumes IPv6 addresses always contain a ":" in the
string...
strMsg = ""
strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer &
"\root\cimv2")
Set IPConfigSet = objWMIService.ExecQuery _
("Select IPAddress from Win32_NetworkAdapterConfiguration WHERE
IPEnabled = 'True'")
For Each IPConfig in IPConfigSet
If Not IsNull(IPConfig.IPAddress) Then
For i = LBound(IPConfig.IPAddress) to
UBound(IPConfig.IPAddress)
If Not Instr(IPConfig.IPAddress(i), ":") > 0 Then
strMsg = strMsg & IPConfig.IPAddress(i) & vbcrlf
Next
End If
Next
Wscript.Echo strMsg
