WSA DNS response times
Hi there,
I would like to know if it is possible to check on WSA appliance DNS request timings from specific time frame in past. I was able to check access logs but they are including only %<d value which is just initial DNS request but not whole DNS timing. Also I would like to know if it is possible to check how long took authentication process during some specific time frame in past - lets say 10 days ago.
Thank you
This was the below dialog steps in the two weeks , how could I explain
Whether things have gone down or not.

Setup is failing because of DNS issues:
PRVF-5636 : The DNS response time for an unreachable node exceeded "15000" ms on following nodes: redhatnode2 - Cause: The DNS response time for an unreachable node exceeded the value specified on nodes specified. - Action: Make sure that 'options timeout', 'options attempts' and 'nameserver' entries in file resolv.conf are proper.

Evertyhing seems correct (at least to me):

It seems to me these response times are high and I wanted to get your opinions. We have 8 WSAs in transparent mode.

ISA Server 2006 + Average response time for Non Cached requests = performance issues?!?!?!
All,
I am in a predicament with internet browsing speeds...We have a 3rd party look after our line and internet facing f/w so I cant troubleshoot them, so at the moment Im looking at ISA as the potential bottleneck - we have a fairly standard environment:
Internal > Local Host > Perimiter n/work > Firewall > Internet
I have been running custom reports on the ISA server to see what data can be collected - I have noticed that "Average response time for non cached requests" (traffic by time of day) can be as high as 76 seconds!!!!!! Cached hits are between .5
and 2 seconds.
I have also coonfigured a connectivity verifier which is also flagging slow connectivity, massively over the >5000ms and also reporting "cant resolve server name on occassions- and this is configured for
www.Microsoft.com --- DNS ???!?!, however I have looked through DNS (no obvious errors / config issues) which I can see
I have run the BPA on ISA server to ensure its Health - - connectivity verifier errors flagged timeouts to microsoft.com as expected...
Can anyone advise any obvious areas to investigate as Im struggling! - as always the 3rd party have told us the internet pipe is fine :OProblem resolved.
DNS forwarders have been changed on the ISA server / DNS and this has improved lookup speed considerably.
thanks all :) -
I am trying to understand the GSS product and how it provides 'immediate' redundancy across multiple data center(s).
So lets assume that the GSS (with CNR installed) has been deployed and functions as the authoritative server for the domain (www.test.com). The goal is to provide active/standby type configuration between two data centers.
If a client tries to access the page (www.test.com), the GSS replies with the address of server (e.g: 1.1.1.1) residing in Data Center(a). However lets assume after the response from GSS is sent to client and the client is trying to connect to the www.test.com using Ip address 1.1.1.1, Data Center(a) becomes unavailable. How will this connection get redirected to Data Center(b)'s IP address 2.2.2.2?
All subsequest request from the client will be done using 'DNS cache' so the GSS does not come into the picture since the client already knows the IP address of www.test.com (1.1.1.1).
Is this how it works or am I missing something here?
Thanks in advance for the response.Syed
There are few things you should keep in mind.
User Workstation is not the real client for GSS. Its primarily the Client's DNS Server.
With respect to caching you are very correct that GSS (for that matter any DNS based GSLB method) is prone to DNS caching issues.
There are various points in the network that stores/caches DNS information.
1. Client's DNS Servers
2. Client PC's OS
3. Browser on Client's PC
To mitigate Client DNS Server issue you need configure the A record served by GSS with a smaller TTL value. This "A-record TTL value" dictates how long can DNS server caches a DNS record. So for example if you set A-record TTL value to 5 minute then the worst outage of service you will get will be 5 minutes (as Client's DNS server will only cache it for 5 minutes and at 6th minute Client's DNS server will contact GSS again and will get the active vip as answer.
If you are using newer IE versions (6.x+) then you are in a better situation as these IEs try to resolve again if the web access to IP in DNS cache fails and hence will get the active IP on GSS.With Pre-6.x versions problem is severe as not only this feature is missing but also the DNS caching time is from 30 mins to 24 hours.
With Firefox (last time I checked) this dns cache timeout is 15 minute (so in worst case scenario the service outage will be 15 minutes).
Using google you can get lots of tools to disable dns caching on browsers. I know this is not a cool solution but it can be done.
In nutshell yes GSLB has issues with DNS caching but it still gives you a solution which can move client to a different Data center (after dns cache timeout).

LYNC 2013 mobility clients disconnect and AAR bad response time
Good day,
I'm new to this, but have to implement LYNC 2013 for our company.
I have implemented Lync 2013 by following various instructions and all seems fine... apart from all mobile clients (internal/external - Andoid/IOS). They get disconnected after a few minutes. On Android the error is "unknown error" (very useful)
and on IOPS it's "unhandeled alert type 302 E_Badgateway (E2-3-35).
What I have noticed is that on AAR, on the LYNCWEB server farm (under " Monitoring and Management") the response time is huge (10000 + ms) and when the errors come up on the clients I get a "failed request".
I can not think what may be wrong but all is pointing to AAR?
AAR is version 3 running on 2021 R2
any ideas? been stuck for a week on this now.
Many thanks
DDHi,
From your description above, it seems to be the issue with IIS ARR.
You can check with the following steps:
Check if DNS records and certificate were appropriate.
Check if ExposedWebURL set to External.
Try to increase the time out value from 200 to 1800
More details:

Is the tnsping value representative of the response time and round-trip to the database?
I am asking because if I ping the database server (from the database server itself), I get 1ms. If I do a tnsping, I get 10-20ms. Is there an issue here?
Components:
- Windows Server 2003 64-bit
- Oracle 11g 64-bit
- Oracle Client for 32-bit
I also tried using the 127.0.0.1 address in the tnsnames.ora file (instead of the server name), but I get the same results.T2C wrote:

The tnsping is just some more overhead away from a basic network ping. Usually if executed more than 1 time, the results get only better.
No issue

But in that case it would affect both network and tnsping

Unable to capture the Citrix network response time using OATS Load testing.
Unable to capture the Citrix network response time using OATS Load testing. Here is the scenario " in our project users logs into Citrix network and select the Hyperion application and does the Transaction and the Clients wants us to simulate the same scenario for load testing. We have scripted starting from Citrix Login and then launching Hyperion application. But the time taken to launch the Hyperion Application from Citrix network has not been captured whereas Hyperion Transaction time have been recorded. Can any help to resolve this issue ASAP?

HP Pavilion hard drive response time is very slow but tests pass (evenutally)
I have owned a HP Pavilion M1199a originally running Windows XP, but has been running Windows Vista 32-bit for the last 3 years or more.
The PC started to lock up for 30 seconds or more (2 weeks ago), with the disk light constantly on then go again for no apparent reason. These lock ups have become more frequent and for longer durations. I removed anti-virus software, and a few other applications/services but generally this computer is fairly clean as I use it as a media center PC.
I have tried checking the disk (SATA) for errors, and it passes although the tests take a lot longer than they should. The resource monitor shows no excess CPU usage and there is plenty of memory available. The disk monitor shows response times of 5000-20000 ms.
What is the best way to proceed from here? Is there a SATA controller or motherboard (ASUS PTGD1-LA) test? Should I buy another SATA drive and try that? I suspect that it is either the drive, drive controller and/or the motherboard that is failing but I don't know how to isolate the problem. The computer hardware configuration has remained the same for years.
The OS has the automatic updates enabled and I uninstalled the recent ones in case they were somehow causing an issue.tr3v wrote:
Thanks for replying.
1/ No, but I am running Vista, so assume this will be the same? Or should I just look at the tmp and temp environment variables to see what folders are being used?
In Vista type temp in the Search programs and files box and double click on the temp files icon that appears above. Delete all the files in the folder that you can. It is safe as they are exactly what they are called and that is temporary files. If you haven't done this ever or in quite a while there should be a noticeable increase in the operating system's response time.
2/ Yes. It completes after a very long time.
5/ No - but will try this out too.

SAP GoLive : File System Response Times and Online Redologs design
Hello,
A SAP Going Live Verification session has just been performed on our SAP Production environnement.
SAP ECC6
Oracle 10.2.0.2
Solaris 10
As usual, we received database configuration instructions, but I'm a little bit skeptical about two of them :
1/
We have been told that our file system read response times "do not meet the standard requirements"
The following datafile has ben considered having a too high average read time per block.
File name -Blocks read - Avg. read time (ms) -Total read time per datafile (ms)
/oracle/PMA/sapdata5/sr3700_10/sr3700.data10 67534 23 1553282
I'm surprised that an average read time of 23ms is considered a high value. What are exactly those "standard requirements" ?
2/
We have been asked to increase the size of the online redo logs which are already quite large (54Mb).
Actually we have BW loading that generates "Chekpoint not comlete" message every night.
I've read in sap note 79341 that :
"The disadvantage of big redo log files is the lower checkpoint frequency and the longer time Oracle needs for an instance recovery."
Frankly, I have problems undertanding this sentence.
Frequent checkpoints means more redo log file switches, means more archive redo log files generated. right ?
But how is it that frequent chekpoints should decrease the time necessary for recovery ?
Thank you.
Any useful help would be appreciated.Hello
>> I'm surprised that an average read time of 23ms is considered a high value. What are exactly those "standard requirements" ?
The recommended ("standard") values are published at the end of sapnote #322896.
23 ms seems really a little bit high to me - for example we have round about 4 to 6 ms on our productive system (with SAN storage).
>> Frequent checkpoints means more redo log file switches, means more archive redo log files generated. right?
Correct.
>> But how is it that frequent chekpoints should decrease the time necessary for recovery ?
A checkpoint is occured on every logswitch (of the online redologfiles). On a checkpoint event the following 3 things are happening in an oracle database:
Every dirty block in the buffer cache is written down to the datafiles
The latest SCN is written (updated) into the datafile header
The latest SCN is also written to the controlfiles
If your redologfiles are larger ... checkpoints are not happening so often and in this case the dirty buffers are not written down to the datafiles (in the case of no free space in the buffer cache is needed). So if your instance crashes you need to apply more redologs to the datafiles to be in a consistent state (roll forward). If you have smaller redologfiles more log switches are occured and so the SCNs in the data file headers (and the corresponding data) are closer to the newest SCN -> ergo the recovery is faster.
But this concept does not really fit the reality because of oracle implements some algorithm to reduce the workload for the DBWR in the case of a checkpoint.
There are also several parameters (depends on the oracle version) which control that a required recovery time is kept. (for example FAST_START_MTTR_TARGET)

Is there a solution to a jerky screen and a slow response time after updating to IOS 8?
Try some basic troubleshooting:
(A) Try reset iPad
Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears
(B) Try reset all settings
Settings>General>Reset>Reset All Settings
(C) Setup as new (data will be lost)
Settings>General>Reset>Erase all content and settings -
Is there a way to speed up the response time from the dock
Is there a way to speed up the response time for external hard drives from the dock? I have three external HDs but when I click on the alias in the dock there is always hesitation before it opens. I'm leaning towards the fact that it is just a result of the fact that the speed of the Mac is what it is. But, maybe there is something I can do to speed it up. The drives are plugged via usb directly to the Mac and they have there own power source. The curious thing is that they once were plugged into a large separately powered USB hub and I don't recall a lag like I have now. Any thoughts? Thanks...

Have a look at the Energy Saver settings in System Preference on the Mac.
Make sure the "Put the Hard Discs to sleep when possible" box is not ticked.
