Client response times

Is there any way that these can be obtained in the access.log?
The Oracle webserver extended log includes a useful parameter (called
time-taken) which gives an approximate client response time. Does
WebLogic have a similar option?

Hi Steve,
WebLogic 5.1 supports Extended Log File format for its access.log. The
format includes the field you are asking about (time-taken) and much
more. Check out the docs for WLS 5.1 and the spec for ELF format at W3C
web site.
Thanks,

Significant difference in response times for same query running on Windows client vs database server

I have a query which is taking a long time to return the results using the Oracle client.
When I run this query on our database server (Unix/Solaris) it completes in 80 seconds.
When I run the same query on a Windows client it completes in 47 minutes.
Ideally I would like to get a response time equivalent on the Windows client to what I get when running this on the database server.
In both cases the query plans are the same.
The query and plan is shown below :
{code}
SQL> explain plan
2 set statement_id = 'SLOW'
3 for
4 SELECT DISTINCT /*+ FIRST_ROWS(503) */ objecttype.id_object
5 FROM documents objecttype WHERE objecttype.id_type_definition = 'duotA9'
6 ;
Explained.
SQL> select * from table(dbms_xplan.display('PLAN_TABLE','SLOW','TYPICAL'));
PLAN_TABLE_OUTPUT
| Id | Operation          | Name      | Rows | Bytes |TempSpc| Cost (%CPU)|
|   0 | SELECT STATEMENT   |           | 2852K|    46M|       | 69851   (1)|
|   1 | HASH UNIQUE       |           | 2852K|    46M|   153M| 69851   (1)|
|* 2 |   TABLE ACCESS FULL| DOCUMENTS | 2852K|    46M|       | 54063   (1)|
{code}
Are there are configuration changes that can be done on the Oracle client or database to improve the response times for the query when it is running from the client?
The version on the database server is 10.2.0.1.0
The version of the oracle client is also 10.2.0.1.0
I am happy to provide any further information if required.
Thank you in advance.

There are NO queries that 'run' on a client. Queries ALWAYS run within the database server.
A client can choose when to FETCH query results. In sql developer (or toad) I can choose to get 10 rows at a time. Until I choose to get the next set of 10 rows NO rows will be returned from the server to the client; That query might NEVER complete.
You may get the same results depending on the client you are using. Post your question in a forum for whatever client you are using.

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

Hi,
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

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.

How to increase built-in cisco vpn peer response timer?

Hi,
I use OS x in-built cisco vpn client to connect to work VPN.
The VPN server, or perhaps the radius server, takes a long time to return a response. OS X always try for 10 seconds, then drop the conneciton when no response from the remote peer. When I use cisco vpn client on a windows machine, the vpn client has a setting to allow for 90 seconds remote peer response time. It works fine using cisco vpn client.
I prefer to use os x as my primary working environment, so I need to fix this problme. My question is how to increase the phase 1 & 2 timer for vpn under 10.6.7. I have tried to change racoon.conf phase 1 & phase 2 timer, but it made no difference. OS X only try for 10 seconds.
Any ideas? (besides asking work people to fix the server or radius problem)
Thanks

Help required in optimizing the query response time

Hi,
I am working on a application which uses a jdbc thin client. My requirement is to select all the table rows in one table and use the column values to select data in another table in another database.
The first table can have maximum of 6 million rows but the second table rows will be around 9000.
My first query is returning within 30-40 milliseconds when the table is having 200000 rows. But when I am iterating the result set and query the second table the query is taking around 4 millisecond for each query.
the second query selection criteria is to find the value in the range .
for example my_table ( varchar2 column1, varchar2 start_range, varchar2 end_range);
My first query returns a result which then will be used to select using the following query
select column1 from my_table where start_range < my_value and end_range> my_value;
I have created an index on start_range and end_range. this query is taking around 4 millisseconds which I think is too much.
I am using a preparedStatement for the second query loop.
Can some one suggest me how I can improve the query response time?
Regards,
Shyam

Try the code below.
Pre-requistee: you should know how to pass ARRAY objects to oracle and receive resultsets from java. There are 1000s of samples available on net.
I have written a sample db code for the same interraction.
Procedure get_list takes a array input from java and returns the record set back to java. You can change the tablenames and the creteria.
Good luck.

How to capture transaction response time in SQL

I need to capture Transaction response time (i.e. ping test) to calculated the peak hours and averaged
on a daily basis.
and
Page refresh time that is calculated no less than every 2 hours for peak hours and averaged on a daily basis.
Please assist

My best guess as to what you are looking for is something like the following (C#):
private int? Ping()
System.Data.SqlClient.SqlConnection objConnection;
System.Data.SqlClient.SqlCommand objCommand;
System.Data.SqlClient.SqlParameter objParameter;
System.Diagnostics.Stopwatch objStopWatch = new System.Diagnostics.Stopwatch();
DateTime objStartTime, objEndTime, objServerTime;
int intToServer, intFromServer;
int? intResult = null;
objConnection = new System.Data.SqlClient.SqlConnection("Data Source=myserver;Initial Catalog=master;Integrated Security=True;Connect Timeout=3;Network Library=dbmssocn;");
using (objConnection)
objConnection.Open();
using (objCommand = new System.Data.SqlClient.SqlCommand())
objCommand.Connection = objConnection;
objCommand.CommandType = CommandType.Text;
objCommand.CommandText = @"select @ServerTime = sysdatetime()";
objParameter = new System.Data.SqlClient.SqlParameter("@ServerTime", SqlDbType.DateTime2, 7);
objParameter.Direction = ParameterDirection.Output;
objCommand.Parameters.Add(objParameter);
objStopWatch.Start();
objStartTime = DateTime.Now;
objCommand.ExecuteNonQuery();
objEndTime = DateTime.Now;
objStopWatch.Stop();
objServerTime = DateTime.Parse(objCommand.Parameters["@ServerTime"].Value.ToString());
intToServer = objServerTime.Subtract(objStartTime).Milliseconds;
intFromServer = objEndTime.Subtract(objServerTime).Milliseconds;
intResult = (int?)objStopWatch.ElapsedMilliseconds;
System.Diagnostics.Debug.Print(string.Format("Milliseconds from client to server {0}, milliseconds from server back to client {1}, and milliseconds round trip {2}.", intToServer, intFromServer, intResult));
return intResult;
Now, while the round trip measurement is fairly accurate give or take 100ms, any measurement of latency to and from SQL Server is going to be subject to the accuracy of the time synchronization of the client and server. If the server's and client's
time isn't synchronized precisely then you will get odd results in the variables intToServer and intFromServer.
Since the round trip result of the test is measured entirely on the client that value isn't subject to the whims of client/server time synchronization.

SG200-26P [FW-1.1.2.0] - Very High Response Time: 1000ms!

Hello,
Problem: New SG-200 26P Smart Switch with Latest Firmware - Very High Responce Time 500-800ms
We've a EdgeMarc 4500 Router with 10 VPN tunnels to 10 brach locations. SG-200 26P Smart Switch is connected to 7 Servers (2 Terminal, SQL, and Other) All locations have 50MB Download and 20MB Upload speed from Verizon FiOS Internet service.
As per the SolarWind tool, the response time of this switch is around at 500ms. At the same time, the EdgeMarc 4500 router response time is around 40ms and less.
We've 60 desktops remotely connected to our SQL Server database and 40 RDP Users via Remote Desktop. The configuration is same from past 3 years. But we change the switch from HP 1800-24G to Cisco due to some Connection Failures. For Connection Failures, we first suspect the old HP switch, but it's look like issue with EdgeMarc Router.
Is this Response Time is normal? I attached two screenshots of both Cisco Switch and EdgeMarc Router Response Time from past 24 hours according to SolarWind tool. Any further advice would be greatly appreciated. Thank you.

Hello Srinath,
Thank you for participating in the Small Business support community. My name is Nico Muselle from Cisco Sofia SBSC.
The response time from the switch could be considered as quite normal. Reason for this is that the switch gives CPU priority to it's actual duties which would of course be switching, access lists, VLANs, QoS, multicast and DHCP snooping etc etc. As a result of that, ping response times of the switch itself do not show in any way the correct working of the switch.
I invite you to try pinging clients connected to the switch, you should be able to notice that response times to the clients are a lot lower than response times of the switch itself.
Hope this answers your question !
Best regards,

EJB slow response time in cluster

We have 2 clusters : cluster 1(3 managed servers) and cluster2( 2 managed servers). We have an EJB deployed on cluster2 which is being called by an application on cluster1. Issue is that this EJB gives a very slow response time (in the order of minutes). There are no errors or exceptions in the logs.
When we shut down one of the nodes on cluster2, the respose from the same EJB is very fast. Please help as to where we should look out for the issue?

Could be that you have a network configuration problem. The source of the problem is how host names and IP addresses are resolved,
and there is a workaround. RMI and other naming services use the InetAddress class to obtain resolved host names and IP addresses.
InetAddress caches lookup results to improve subsequent calls, but when it is passed a new IP address or host name, it performs a
cross-reference between the IP address and the host name to prevent address spoofing. If you supply the host name as an IP address,
InetAddress still tries to verify the name of the host. To workaround this problem, include the host name and IP address in the
hosts file on the client, for example,
127.0.0.1           localhost
172.30.0.129      SomeWebLogicServerHostName
172.30.0.130      SomeOtherWebLogicServerHostName

Response time of query utterly upside down because of small where clause change

Everything that comes inside the "select * from(...) view" parentheses is defined in a view. We've noticed that the line "AND d.payed = 'N'" (commented above) is the guilty clause: the query takes one or two seconds to return between 400 and 500 rows if this line is removed, when included in the query, the response time then switches to *hours* -sic !- but then the result set is empty (no rows returned). The plan is exactly the same whether this "d.payed = 'N'" is added or removed, I mean the nb of steps, access paths, join order etc., only the rows/bytes/cost columns values change, as you can see.
We've found no other way of solving this perf issue but by taking out this "d.payed = 'N'" condition and setting it outside the view along with view.DISTRIB_CODE and view.TIME_OPERATION.
But we would like to understand why such a small change on the XYZ.PAYED column turns everything upside down that much, and we'd like to be able to tell the optimizer to perform this check on payed = 'N' by itself in the end, just like we did, through the use of a hint if possible...
Anybody ever encountered such a behaviour before ? Do you have any advice regarding the use of a hint to reach the same response time as that we've got by setting the payed = N condition outside of the view definition ??
Thanks a lot in advance.
Regards,
Seb

I am really sorry I couldn't get back earlier to this forum...
Thanks to you all for your answers.
First I'd just like to correct a small mistake I made, when writing
"the query takes one or two seconds": I meant one or 2 *minutes*. Sorry.

> Have you traced both cases to compare statistics? What differences did it reveal?
Yes but it only shows more of *everything* (more tables blocks accessed, the same
for indexes blocks, for almost all objects involved) for the slowest query !
Greping WAIT on the two trc files made for every statement and counting the
object IDs access show that the quicker query requires much less I/Os; the
slowest one overall needs much more blocks to be read (except for the indexes
DNSG_NI1 or DNPE_XYZ for example). Below I replaced obj# with the table/index
name, the first column is the figure showing how many times the object was
accessed in the 10053 file (I ctrl-C'ed my second execution ofr course, the
figures should be much higher !!):

Tnsping, high response time

Hi,

tnsping response time is very high:

Slow response time for radio buttons on Internet Explorer 7

Hi,
We're using ADF 11.1.1.4 on weblogic 10.3.4 on a Solaris 10 (sparc) platform. The architecture also uses OHS and Webcache 11.1.1.4.
One of our applications has a webpage that is composed of several tabs, inside each tab we have some questions with radio buttons. When a client responds all questions on the first tab it moves to the second, where the application loads the necessary questions, based on the answers provided on the first tab. Once the client finishes answering this tab it moves to the third one and so on.
The problem appears once the tabs are loaded. Each time the client clicks one of the radio buttons, Internet Explorer takes between 3 to 5 seconds to return control, and considering that a client might need to click dozens of radio buttons to complete a process, it becomes a very exhausting task. It's worth noting that the session information is persisted for each radio button, when we move between tabs all answers are kept even if we didn't saved the progress.
On the other side, if we use Google Chrome 16, we find that the webpage returns control to the user almost inmediately, when clicking the radio buttons the response time is usually at 1 second or less.
We've checked that the app server is not stressed, heap memory is nowhere near the maximum assigned and the used processor % is very low, so it does not seems to be a resource problem.
Is there any known issue with ADF 11.1.1.4 and IE7/8 that affects the browser's response time? Are there any guidelines or recommendations regarding how to make the radio button component work properly? Has anybody noticed this behavior in adf?
Thanks.

I think that the most accurate description of the problem is that the autosubmit action of the radio button takes considerably longer in IE7 than in Chrome.

Response time https/http using CSM+SSL versus CSM

Im using C6K and CSM for load balancing and an SSL module for https termination. That means clients can access the serverfarm through https/http and compare response time values.
What should be the expected delay generated from SSL(https) compared to cleartext(http) ?
My customers are complaining about to much delay...
Thanks in advance for your answer.
Volker

it's difficult to answer.
There will be an initial delay required to establish the ssl session, then for each packet there will be additional delay to encrypt/decrypt the packet.
It also depends on load.
An CSM can handle lot of traffic but not an SSLM.
So, if you see something wrong in a sniffer trace like packet drops, retransmits, huge delays per packet [like 300ms], then we need to investigate what is going on.
Otherwise, this would be normal.
Regards,
Gilles.

Response time of form

I developed a form with triggers like key-up,key-down, post-query, on-lock in three blocks. It works fine in client server environment but when I run the form from the web server it slows down and a job that it has to do on one click of a button actually does when clicked three times.
In master detail blocks which are both in tabular form I have placed an additional field which works as a current record indicator and when I scroll through the records the current record indicator lacks behind.
I even have removed most of the triggers but still the response time is very very poor.
I am using form server with Appachi web server.
