Response to any key stroke delayed 3-8 seconds, running windows XP on Dell..formally no problem on generic PC
== This happened ==
Every time Firefox opened
== move in hardware..to Dell

check if the file /opt/bobj/DI/log/Server1/dbometa__msykora/error_07_17_2009_09_14_56_23__d16337cb_3c6d_4bac_9ae0_f92ee944a47f.txt.idx exists or not ? it does exist
have you tried increasing the number of file descriptors ? capped at 1024
there was a issue fixed related to same error, in 11.7.3.7
you can try following
Add the following in the $LINK_DIR/bin/DSConfig.txt in the AL_Engine section on the job server machine
fileopen_retry_time=90
First try with 90 then with 120
=>added to DSConfig.txt but no effect
also are you able to reproduce this error all the time or its random ? all the time
are you running Dataflows in paralle ? yes
if so how many DF are running in parallel ? 3

HTTP response time - From any SAP table.

Hi,
Can we get http response time other than from SMICM u2192 Http log?
Reason for me to ask is we cannot see complete URL in smicm log with response time.
date - "POST /sap/bc/webdynpro/sap/cprojects/?sap-contextid=......................................... HTTP/1.1" 200 325894 9555 h[-]
As per sap help link complete URL after contextID is hidden for security reason.

u201CFor security reasons the following information is hidden (replaced with points) from the logging procedureu201D
Question: can we access complete URL from any table level with http response time, any input is appreciated.
Thanks,
Venkat.

Michael,
First of all, thanks for the reply.
In our environment we have cprojects implemented and have lot of webdynpro request to ECC system.
From http log (SMICM) I can see many webdynpro requests with response time above 30 minutes; I want to automate this monitoring by writing a CCMS data supplier. We already have SAP document to write data supplier.
Scenario: For example if they are doing a task in cprojects.
We will be having a GET webdynpro request and then POST. By looking at GET we can know the task user is trying to do. But it is POST request which will be taking most of the response time and POST URL is show u2026(point) after context ID and as per SAP help this is done for security reason.
HTTP log from SMICMu2026
[DATE] - "GET /sap/bc/webdynpro/sap/cprojects?sap-client=clnt&STARTVIEW=Tasks&OBJECT_TYPE=TTO&GUID=GUIDNUMBER
[DATE] - "GET /sap/bc/webdynpro/sap/cprojects/~ucfLOADING?sap-contextid=....................
[DATE] - "POST /sap/bc/webdynpro/sap/cprojects/?sap-contextid=........................[response time]
I think SAP is displaying as point in http log file, but it should definitely have complete URL is any of the table.
So I am looking If we can find the complete POST URL with response time from table then we can write an ABAP program to send the information to CCMS.
Thanks,
Venkat.

In the new firefox (34) i started having a problem entering anything in the search bar or address bar. Any key stroke i make is changed to a random character

Keystrokes do not reflect what I am trying to type in Firefox 34. This just started today. I had to use IE Explorer which I hate to send this to you. I reset firefox twice but no help. Uninstalled it and reinstalled an older version and all was well. Reinstalled the latest version and I am back to the keystroke problem again. HELP !!!!!

After editing a message in firefox (whether yahoo mail or any other app) the keyboard stops working and I just get an audio sound with any key stroke.

This problem occurs with any page that requires keyboard input. If I make an errot in typing and have to go back or edit a sentence the keyboard stops working. THis only happens with Firefox and not with any other browser (Chrome, Safari etc)

Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
Thank you.

Response time & dump-allowed & disable connection pooling

3 Questions:
Question 1:
Where do I find status report when I set "dump-allowed" to yes? Where does it get "dumped"? I've looked in servlet log files, such as:
1. C:\Program Files\New Atlanta\ServletExec ISAPI\Servlet Logs\Servlet.Log
C:\WINNT\SYSTEM32\LogFiles\W3SVC1\exyymmdd.log
in a NewAtlanta ServletExec 4.1 for IIS/PWS 5.1 scenario AND
2. C:\oracle\ora81\Apache\Jserv\logs\Jserv.log
C:\oracle\ora81\Apache\Apache\logs\access_log
in a Apache 1.3.12 with JServ 1.1 scenario (the versions that come with Oracle 8.1.7 on W2K).
but cannot find any connection pool dump information in any of the above log files.
Is there documentation on "dump-allowed" other than the short blurb in the XSQLConfig.xml file?
Question 2:
Does setting the following connection pool elements, initial & increment, in the XSQLConfig.xml file
<initial>1</initial>
<increment>1</increment>
to 1 & 1 respectively, actually DISABLE connection pooling?
When I set the timing-info element to "yes", I see about 2 to 4 second response time to any of the Insurance demos at the outset. This is probably normal to establish the first connection and to process the SQL statement. However after 60 seconds, which is the setting for the timeout-seconds element, I again see about 2 to 4 second response time. I expect a response time under 1 second because not only should the SQL statement be cached since it had previously been parsed, the initial connection should still be live.
Thus it seems that an initial setting of 1 does not do what it's suppose to do, and that is maintain a connection pool of 1.
I thought I had read in the XML forum that:
<initial>1</initial>
<increment>0</increment>
does disable connection pooling. Not sure how and why. What does disabling connection pooling really mean anyway?
BTW I'm using XDK 9.2.0.1.
Question 3:
The real reason behind questions 1 & 2. How do I track response times from end to end?
I know about setting timing-info element to "yes" in the XSQLConfig.xml file.
<timing-info>
<page>yes</page>
<action>yes</action>
</timing-info>
However if I want to know where a hold up is, timing-info is not enough.
How do I turn on sql trace for the session affiliated each JDBC connection. I know about setting time_statistics= true in the init.ora file, but how do I alter session set sql_trace=true for an XSQL query action?
I think I answered this question. See following amended claim1.xsql file for the Insurance example:
Claim1.xsql:
<?xml version="1.0"?>
<page connection="demo" xmlns:xsql="urn:oracle-xsql">
<xsql:dml><![CDATA[
ALTER SESSION SET SQL_TRACE = true
]]></xsql:dml>
<xsql:query><![CDATA[
select value(c) as Claim from insurance_claim_view c
where c.claimpolicy.primaryinsured.lastname = 'Astoria'
]]></xsql:query>
<xsql:dml><![CDATA[
ALTER SESSION SET SQL_TRACE = false
]]></xsql:dml>
</page>
The result of which is:
<?xml version="1.0" ?>
- <page xsql-timing="3485">

<xsql-status action="xsql:dml" rows="0" />

- <ROWSET>
- <ROW num="1">
- <CLAIM>
<CLAIMID>77804</CLAIMID>
<FILED>1/1/1999 0:0:0</FILED>
</CLAIM>
</ROW>
- <ROW num="2">
- <CLAIM>
<CLAIMID>12345</CLAIMID>
<FILED>3/11/1998 0:0:0</FILED>
</CLAIM>
</ROW>
</ROWSET>

<xsql-status action="xsql:dml" rows="0" />
</page>
and in the database trace file:
select value(c) as Claim
from insurance_claim_view c
where c.claimpolicy.primaryinsured.lastname = 'Astoria'
call count cpu elapsed disk query current rows
Parse 1 0.00 0.08 0 0 0 0
Execute 1 0.00 0.07 0 0 0 0
Fetch 1 0.00 0.21 0 11 12 2
total 3 0.00 0.36 0 11 12 2
Do I use the elapsed time to understand the time spent in the db? Do I consider the other SQL statements in the trace file that seem to deal with the page request? If so, then there is an overall timed total provided.
OVERALL TOTALS FOR ALL NON-RECURSIVE STATEMENTS
call count cpu elapsed disk query current rows
Parse 14 0.00 0.20 0 0 0 0
Execute 15 0.04 1.07 0 14 0 6
Fetch 7 0.00 0.38 0 210 12 21
total 36 0.04 1.65 0 224 12 27
Misses in library cache during parse: 0
OVERALL TOTALS FOR ALL RECURSIVE STATEMENTS
call count cpu elapsed disk query current rows
Parse 2 0.00 0.16 0 0 0 0
Execute 7 0.00 0.04 0 0 0 0
Fetch 7 0.04 0.25 0 56 0 7
total 16 0.04 0.45 0 56 0 7
Misses in library cache during parse: 0
So do I use overall elapsed time in db affiliated with the Claim SQL statement, which is 2.1 seconds? Is the 3.5 seconds in the XSQL timing an elapsed time, and does it include time spent (2.1 seconds) in the database?
I guess you can see where this is going. What I really need is a recommended plan to analyze response time problems.
Has anyone come across this respose time problem, and how did you attack the problem? Did you use timing-info and cross check with database timed statistics using tkprof? What database statistics did you use?
How does one analyze response time even further. For example how does one track time within the web server? How does one track time within the servlet engine?
Ideas anyone?
Steve.
The section of the XSQLConfig.xml file to which I refer:


[list=1]
[*]Where do I find status report when I set "dump-allowed" to yes?
The report is returned in the browser.
[*]Does setting the following connection pool elements, initial=1 & increment=1 actually DISABLE connection pooling?
No. This tells the pool to start a one connection, and to grow by one connection whenever the pool finds all current connections in-use in the pool.
When I set the timing-info element to "yes", I see about 2 to 4 second response time to any of the Insurance demos at the outset.
Initial = 1 means that the pool will start with 1 connection. It also means the pool will never shrink to below 1 connection.
I thought I had read in the XML forum that initial=1, increment=0 disables connection pooling.
Setting increment=0 forces the pool never to grow, but if you have more than one user this is not a desireable situation to be in. It will cause potential delays for users contending for the one connection available.
[*]How do I track response times from end to end?
<timing-info> is the only XSQL pages specific timing info available. You saw how to use <xsql:dml> to turn on tracing. Once you have the trace output, the analysis is a database profiling task.
[list]
You can experiment with the fetch-size parameter to see if increasing the number of records fetched at a time will improve your throughput.

Why does HP LoadRunner measure slow response time for SAP GUI selection steps?

We are running HP LoadRunner 11.52 scenarios out to multiple (up to 4) load generators. Load generators have 24 GB ram and 8 CPU's. We have run a maximum of 200 users and see a maximum usage of ~25% on CPU's. We were previously running SAP GUI 7.4 and downgraded to 7.3 when we came to understand 7.4 is not supported in PAM for LR 11.52. Regardless, our results have not changed. What we are trying to resolve is why the first two steps of opening the SAP GUI and entering system-related selection is taking so long to process? Additionally, we typically see that during the time escalation of those steps, that there is a period where the process seems to pause for a large time gap. The process below shows a snapshot while in progress. The SAP GUI steps are hitting severe peaks wthile all other steps during the process tend to track at a steady quick response time. Any degradation there looks to be tied to the long pauses.
Would anyone have knowledge or experience with this type of output and understand why it might be consistenty happening? Thanks.

How to detect any key pressed for program running in the background?

Hi All,
is it possible to detect when any key is pressed if a java program is not in the focus? For example, when I have a console based program I can write something like:
System.in.read();
and wait until any key is pressed. However, if I move the mouse away from the console and make any other window active, the console program "doesn't hear" anything. Ok, it's clear, of course, but how is it possible to make the program detect any keys pressed even if it's running in the background?
Thanks a lot for any hints!

There are very few legitimate problem domains that would require what you are asking about. There are illegitimate ones though. And the legitimate ones would generally require someone with quite a bit of programming experience and would also be required (the fact that java can't do it would not get rid of the requirement.)
Thus one might make assumptions about your intentions.

My G5 won't boot up. The Gray screen comes on and it thinks about it until the fan revs up like it is about to explode. A friend said to start it up with the OS disk and then go to utilities. Didin't work. Any suggestions? Isn't there a key stroke to help

Oh, so this is where I ask my question. Sorry, first time here. As I was saying in my long intro, the gray screen come up and the thing is spinning at the bottom, but nothing happens. Then the fan starts reving up like it is about to explode and I have to manually shut it off. A friend told me to start it up with the OS disk and then go to utilities. I couldn't find the thing, so I went out and bought another. Needless to say, it didn't work. Is there a key stroke to help jump start the machine? How can I get into this thing? I would prefer not to take it in because there are a lot of things on there I don't want just anyone to have access to.Thanks, in advance, for your help!

Never bother with or use the drive or reinstall while there are errors. Don't take a "clean' bill from Apple Disk Utility to mean there are no errors. Only that it didn't find what it looked for.

The Utility menu is on the menu bar of an "OS X Install DVD" and at the point where you get to but stop at "install....' for OS X. you probably do need to install OS X on another drive to work from.
Oh, a real severe issue and damage to the drive directory or filesystem CAN in cases prevent booting from DVD (the system still tries to find and see what boot volumes are present) and can help to pull or disconnect the drive. Putting a drive in a FW case to turn on after startup is very useful.

Boot off your *original* Install Disk while holding down the *d key*, (not c key), then run the extended Apple Hardware Test. Some disks require you to use the Option key at bootup to select AHT. Some models have a separate AHT CD. Some have it on the Disc #2.

Any way to improve response time with iPhoto 8.1.2 using Mountain Lion ? Can you store photos on a separate hard drive and use a smaller file for openning iphoto?

How did you move your iPhoto library to the new system? the recommended way is Connect the two Macs together (network, firewire target mode, etc) or use an external hard drive formed Mac OS extended (journaled) and drag the iPhoto library intact as a single entity from the old Mac to the pictures folder of the new Mac - launch iPhoto on the new mac and it will open the library and convert it as needed and you will be ready move forward.

Do you have multiple keyboard layouts installed?
It is possible that you have switched the keyboard layout by accident.

Windows remembers the keyboard layout setting per application and you may have changed the keyboard layout by accident via a keyboard shortcut.

* Make sure that you have the Language bar visible on the Windows Taskbar
* You can do that via the right-click context menu of the Taskbar: Toolbars > Language Bar
* Check the keyboard language (keyboard layout) setting for the application that has focus via the icon on the Language bar
* You need to do that while Firefox has focus because Windows remembers the keyboard layout setting per application
