Howto capture/replay workload (for performance testing purposes)

Hi,
We have a customer that will buy new hardware for his Oracle database server. Because he is hesitating between 2 possible storage solutions and is not convinced that solution A will be significantly better than solution B he wants a proof of concept.
So this is what we will do:
- Set up a test environment with hardware solution A and another one with hardware solution B.
- We will backup and restore his database on both test servers.
- We will run a workload on both servers and monitor performance with AWR and ADDM
- Compare performance
I would like to:
- Make a consistent backup of the production database
- Capture 24 hours work on the customers production database
- Restore database on both test servers.
- Replay the captured workload on both test servers.
- Compare performance
Does anyone know what tools I can use to do the capture/replay part?
All suggestions are appreciated.
Thank You,
Pieter

I have been playing with logminer and auditing but these don't solve the problem for 100%...
Start logminer:
EXECUTE DBMS_LOGMNR.START_LOGMNR(-
STARTSCN => 404809, -
ENDSCN => 404975, -
OPTIONS => DBMS_LOGMNR.DICT_FROM_ONLINE_CATALOG + -
DBMS_LOGMNR.CONTINUOUS_MINE + -
DBMS_LOGMNR.COMMITTED_DATA_ONLY + -
DBMS_LOGMNR.NO_ROWID_IN_STMT);Get SQL:
SELECT SQL_REDO FROM V$LOGMNR_CONTENTS WHERE USERNAME != 'SYS'
AND SEG_OWNER IS NULL OR SEG_OWNER NOT IN ('SYS', 'SYSTEM', 'SYSMAN');This works for insert/update/delete, but it can't capture selects...
Auditing:
AUDIT SELECT TABLE, INSERT TABLE, DELETE TABLE, EXECUTE PROCEDURE BY ACCESS;
SELECT SQL_TEXT FROM DBA_AUDIT_TRAIL;These sql_text statements show the bind variables
eg: SELECT TO_NUMBER(PARAMETER_VALUE) FROM MGMT_PARAMETERS WHERE PARAMETER_NAME = :B1
This is not executable, I need an executable result...
Does anyone has a better way to accomplish what I need?
Thank You.

HTTP Receiver for Performance Testing

Dear Experts,
I need to send the Asynchronous XI responses back to HTTP client for performance testing. Any suggestions how this can be achieved?
Thanks,

Hi,
>>>.I'm not sure if HTTP receiver adapter can be used for this to send it back to the HTTP test client?
no, it cannot htt test client can work in sync mode or async - async does not have any reponses
>>>But, my requirement is to test the performance of 2 asynchronous Webservice performances. We send the SOAP request via HTTP
but this is so simple - send HTTP call to SOAP and from SOAP you send it to the final receiver right ?
at the end of receiver processing create a call to XI again and send via HTTP to where ever you want
or to a file if you want to test receiver processing only
I don't see any issue here...

Is there any tool uses Selenium tests for performance test

Hello!
I am looking for a tool for using performans test.
I have Selenium test scenarios and I want to use them for performance tests.
Which tools use Selenium tests for performance tests or
Which are the best tools to test a JSF Application? Which experiences
have you made?

Hi,
If you have the test kit installed i.e. the CTK , then you will find it under the corresponding test folder. For example , i have it under C:\Program Files (x86)\WindowsEmbeddedCompact7TestKit\tests\target\
The test harness files , tux and kato can be found under
C:\Program Files (x86)\WindowsEmbeddedCompact7TestKit\harnesses\target\
The above two files tux and kato would be required for running any tests on Windows embedded compact platforms.
Depending on your platform , you may choose to use the corresponding binaries in the sub directory.

I am currently on v3.6 and want to download v6, for browser testing purposes. Where do I find a link to download v6?

I want to download v6, but can only find v7. Browser stats say that most users currently have v6, so this is the version I want to test our website in, but can't find it to download.

I understand you are only using this for testing purposes, but note that Firefox 6 is no longer supported or considered secure. At the moment and for the immediate future the oldest supported version is Firefox 3.6.23 (3.6.24 due soon).
Firefox 4,5, & 6 are now not supported, but Firefox 7 is the standard release, with some users also on Firefox 8,9 and 10.
No doubt you are aware Firefox is now using a revised rapid release cycle, usually resulting in releases of a new version every six weeks !

How/What can we monitor in DB02 for performance testing?

We are conducting a performance test/load before golive of HCM in SAP.
I am looking at DB02 but have NO idea of what to monitor for? there is so MUCH
Any suggestions, would certainly be appreciated asap
Thank you so much!
maria

Well, rather than trying to explain in the forum, I suggest you download the document "The SAP DBA Cockpit for Microsoft SQL Server" from:
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/1062428c-f1df-2910-b08f-c322feddcd10?quicklink=index&overridelayout=true
This will explain everything you need to know about DB02 transaction for MS SQL server. You can read through it find out what all monitoring can be done.
You can check the following Areas:
Performance (ST04)
Space (DB02)
Configuration = Some ST04 detail screens plus new ones
Diagnostics = Some ST04 and DB02 detail screens plus new ones
Frankly, Space and performance are the main areas.
Refer to the guide and this should solve all your doubts.

Shitij

Tools for Performance Testing ?

All
We are planning to upgrade to Oracle version 10.2.0.4 in SAP landscape.
Here is my question:
We have one SAP box Oracle version 10 and other SAP box is with Oracle version 10.2.0.4.
Before upgrading to Oracle version 10.2.0.4 in the Production, we wanted to test the performance of Oracle version 10.2.0.4,
So we decided to run programs(report) in Oracle ver 10 box Vs Oracle version 10.2.0.4 box to check how system taking time to execute.
But my question is whether do we have any kind of performance analyser tools in SAP so that we can cross check with both the boxes performances.
I heard tool called coverage analyser is it works in this scenario.

Need help trying to determine what hardware I can run for develpoment testing purposes for Solaris Sparc 11.2

I have a large client that is looking to upgrade from Solaris 5.9 up to Solaris 11.2. I need to find some hardware I can run in house to do development, run tests and run setups/configuration on a 64 bit Sparc machine. I know Solaris 11 dropped support for some of the UltraSPARC II, III, IV series. However I need to have a setup in shop locally for me to work on. Any ideas on if buy a sun blade workstation or another workstation that I could get Solaris 11.2 installed? I don't necessarily need the GUI desktop but the text/curses based setup is all I need. Any ideas on where to go? Seems like the cutoff from Solaris 10 to 11 was a pretty big one regarding legacy support of older hardware. Also I know there are x86 distributions of Solaris 11.2 but I have 3rd party software that is compiled on Sparc.

Have you seen the HCL?
I write most of my labs on Virtual Box, and also use a few older 5440s and some new M10s when I want to shoe LDOMs.

Can we Use GGate to multiple data for performance testing?

Hi,
My team has a requirement were we would like to multiply data 2x, 4x, 8x time so that we hava a good amount of data for testing in DB. We have a Master data created and using the reference to that master data we wanna do the multiplication.

Say I have 10 records in DB.
Now Can I increase the data to 20, then to 40 and So on by taking this 10 records as master and changing their Ids/other details that needs to be unique.
And ya that should be in the same DATABASE (DB1 ---- 2X---> DB1)

Oracle Lite Performance Testing

Hi All,
Is there a way to sync more than one client from the same PC/Laptop to simulate a concurrent sync for performance testing purposes? Greg Rekuonas did mention, some script available by Oracle Support for the same. Oracle (on raising an SR) unfortunately says that they cannot make that available to customers.
I have found a way out, but it involves changing one of olite's dll's and was wondering if anyone else knew a better solution.(Other than finding 50-100 different laptop's/handhelds and make them all synchronize one by one).
Cheers,
Vikrant

Hi Greg,
Thanks for the reply. I will try and re-raise it with them, though they have closed my SR with a "Not Entitled" status.
In case anyone is interested I finally, got the trick done by using the following:-
1) Open ocapi.dll in your $MOBILE_HOME/bin folder. (Right where the msync_java.dll is there)
2) Open the above file in a text editor like EditPlus(Note this is a binary file)
3) Search for the string OracleLiteSync.
4) Change the string to something else(Do not add any characters, just change any one alphabet).
5) Save this file as ocapi.dll in a different directory.
I wrote a standard java program, to programatically trigger a synchronization. To, handle concurrent synchronizations, I create multiple copies of ocapi.dll with different strings for OracleLiteSync.
Each of my simulation "Clients"(Basically Java Threads) were invoked with a different path each pointing to a different ocapi.dll. This seemed to work, and the "Mutex" error went away.
The exaplanation is that basically OracleLite uses the Kernel32 API CreateMutexA to create a mutex to ensure that two synchroninzations cannot happen on the same machine. The mutex name is OracleLiteSync and the code is in ocapi.dll.
By changing the mutex name and using a different version of ocapi.dll (Oracle Lite uses JNI which reads DLL from the PATH environment variable) you can fool Oracle Lite into doing different synchronizations.
This did give me some errors when it tried to apply the downloaded changes simultaneously in different ODB's, but allowed me to load the mobile server concurrently with syncrhonization sessions.
Cheers,
Vikrant

[Ann] FirstACT 2.2 released for SOAP performance testing

Empirix Releases FirstACT 2.2 for Performance Testing of SOAP-based Web Services
FirstACT 2.2 is available for free evaluation immediately at http://www.empirix.com/TryFirstACT
Waltham, MA -- June 5, 2002 -- Empirix Inc., the leading provider of test and monitoring
solutions for Web, voice and network applications, today announced FirstACT™ 2.2,
the fifth release of the industry's first and most comprehensive automated performance
testing tool for Web Services.
As enterprise organizations are beginning to adopt Web Services, the types of Web
Services being developed and their testing needs is in a state of change. Major
software testing solution vendor, Empirix is committed to ensuring that organizations
developing enterprise software using Web Services can continue to verify the performance
of their enterprise as quickly and cost effectively as possible regardless of the
architecture they are built upon.
Working with organizations developing Web Services, we have observed several emerging
trends. First, organizations are tending to develop Web Services that transfer a
sizable amount of data within each transaction by passing in user-defined XML data
types as part of the SOAP request. As a result, they require a solution that automatically
generates SOAP requests using XML data types and allows them to be quickly customized.
Second, organizations require highly scalable test solutions. Many organizations
are using Web Services to exchange information between business partners and have
Service Level Agreements (SLAs) in place specifying guaranteed performance metrics.
Organizations need to performance test to these SLAs to avoid financial and business
penalties. Finally, many organizations just beginning to use automated testing tools
for Web Services have already made significant investments in making SOAP scripts
by hand. They would like to import SOAP requests into an automated testing tool
for regression testing.
Empirix FirstACT 2.2 meets or exceeds the testing needs of these emerging trends
in Web Services testing by offering the following new functionality:
1. Automatic and customizable test script generation for XML data types – FirstACT
2.2 will generate complete test scripts and allow the user to graphically customize
test data without requiring programming. FirstACT now includes a simple-to-use XML
editor for data entry or more advanced SOAP request customization.
2. Scalability Guarantee – FirstACT 2.2 has been designed to be highly scalable to
performance test Web Services. Customers using FirstACT today regularly simulate
between several hundred to several thousand users. Empirix will guarantee to
performance test the numbers of users an organization needs to test to meet its business
needs.
3. Importing Existing Test Scripts – FirstACT 2.2 can now import existing SOAP request
directly into the tool on a user-by-user basis. As a result, some users simulated
can import SOAP requests; others can be automatically generated by FirstACT.
Web Services facilitates the easy exchange of business-critical data and information
across heterogeneous network systems. Gartner estimates that 75% of all businesses
with more than $100 million in sales will have begun to develop Web Services applications
or will have deployed a production system using Web Services technology by the end
of 2002. As part of this move to Web Services, "vendors are moving forward with
the technology and architecture elements underlying a Web Services application model,"
Gartner reports. While this model holds exciting potential, the added protocol layers
necessary to implement it can have a serious impact on application performance, causing
delays in development and in the retrieval of information for end users.
"Today Web Services play an increasingly prominent but changing role in the success
of enterprise software projects, but they can only deliver on their promise if they
perform reliably," said Steven Kolak, FirstACT product manager at Empirix. "With
its graphical user interface and extensive test-case generation capability, FirstACT
is the first Web Services testing tool that can be used by software developers or
QA test engineers. FirstACT tests the performance and functionality of Web Services
whether they are built upon J2EE, .NET, or other technologies. FirstACT 2.2 provides
the most comprehensive Web Services testing solution that meets or exceeds the changing
demands of organizations testing Web Services for performance, functionality, and
functionality under load.”

Simon,
I will admit, I almost never use SQL Developer. I have been a long time Toad user, but for this tool, I fumbled around a bit and got everything up and running quickly.
That said, I tried the new GeoRaptor tool using this tutorial (which is I think is close enough to get the jist). http://sourceforge.net/apps/mediawiki/georaptor/index.php?title=A_Gentle_Introduction:_Create_Table,_Metadata_Registration,_Indexing_and_Mapping
As I stumble around it, I'll try and leave some feedback, and probably ask some rather stupid questions.
Thanks for the effort,
Bryan

Application Insights for load testing in VS 2013, Azure Preview or Visual Studio Online?

I'm trying to get some clarification on which version of application insights to use to get performance counters from application insights for my azure cloud service for load and performance testing purposes.
So far, its not be clear what the differences between the two versions are, after deploying first the Azure Preview version, I attempted to set up performance counters using application insights but was shown an error because my visual studio online account
did not have an associated application insights instance.
Is it possible to get performance counters using AI for load testing using the Azure Preview version? If so, how? If not, is that planned as a new feature or will performance counters for VSO cloud based load testing have to be used when support for the
VSO version of application insights is eventually dropped?
Thanks,
Luke

Hi Alex, thanks for your response. I do have an Azure account, and have tinkered with AI in Azure Preview. My question was more about what the differences between the VSO and azure preview versions of AI are.
When I initially deployed AI to the azure portal and tried to run load tests from visual studio (cloud load tests, that is) I could not. Its possible I had made a mistake in configuring the azure version of application insights though. Strangely enough,
I actually do still see application insights data in the azure preview portal after I removed the newer AI version and installed AI 1.3.
To clarify my question, is it or will it be possible to run cloud based load tests (using visual studio online or another integrated service) against a azure web role deployed with application insights for azure and get performance counters of the system
under test via AI? To do that, will I also have an application insights application in the visual studio online account (similar to how I do now with the VSO version of AI), because that seems to be a requirement to load performance counters from application
insights within visual studio.
Thanks and sorry if I misunderstood your answer.
