Database base storage stress test
Hi,
I have a ucm 11g instance up and running with SSO.
I need to test database storage against filesystem storage.
Does anyone have any suggestions on how to test this?
Also I'm sure I read somewhere (but I can't find it now) that once I go in one direction I can't go back, does anyone have any details about this?
Many thanks
James
First of all, take a look at File Store Provider (here: http://download.oracle.com/docs/cd/E14571_01/doc.1111/e10792/c02_settings005.htm#CSMSP445)
In general, filesystem storage is always used even if you store data in the database, in the end. It is, though, understood as a temporary storage. In theory, you can keep your files in both locations and I see no reason why you should not be able to go from FS to DB and back, BUT you have to consider consequences (you might have to rebuild indexes or even migrate data from one storage to the other).
As for stress tests, first you have to decide WHAT you want to test. Potential candidates are:
- checkin of a single item (wasted effort: since FS is always used as an intermediate storage it will always be a bit faster)
- mass checkin (e.g. from Batch Loader - especially if you use Fast Checkin settings, db can be a bit faster, but you will need a real lot of small files)
- search
- update (metadata - wasted effort: should be the same)
- backup
- migration of content
Then, you will have to setup two environments with more-or-less the same conditions (CPU power, memory, disk speed).
And finally, you will have to create and run you test cases. I'd suggest to automate stress tests via writing a program calling the same services with the same data. Use WebServices (if non-Java) or RIDC (if Java).
Alternatively, if your task is "to get results" rather than "perform stress tests", you could try to approach consulting services or project managers to provide some normalized results for you. Something can be obtained in this whitepaper: http://www.oracle.com/us/products/middleware/content-management/ecm-extreme-performance-wp-077977.pdf

Toplink session is configured to use external transaction controller and data source. Application run on OC4J 9.0.4.1. Using jdbc debug options I wasn't able to find any causes. Has anyone faced this problem before?
Regards
JarekHi Jarek,
TopLink uses the datasource similar to any other java application would, so there are no additional restrictions. From the error, you can see that the datasource is attempting to create a new connection and that is what is causing the exception. All TopLink did was call getConnection on the datasource ( DriverManagerDataSource.getConnection ).
This could be a problem/glitch with the network or that the listener when down temporarily. Things to check would be:
-how frequently this occurs
-if it occurs for all connections after this point
-the state of the database listener (can other applications connect to it, is it up, etc)
-how many connections to the DB are active at this point
-how many connections/sessions are active from this application
-the OC4J and JDBC versions. Latest patches are better with regards to connection pools.
What is strange though is that you have the min=max, so it should never create new connections after the first time the pool is accessed. Each connection should already have been created, which is why I suggest that you contact OC4J/JDBC support.
Best Regards,
Chris -
Hi,
I have planned to do the Stress testing of our application by posting many transactions and running jobs. I would like to know what are all things in database I need to monitor during this stress test
Thanks,
KarthikWell, the most important is going to be whatever metric your users are going to be using. Since it sounds like you're building an OLTP application, I'm assuming that that metric is response time-- how long it takes between the time they hit a button and they get a response.
I would assume that you'd want to monitor CPU and memory utilization on the machine to see what kind of a load you're putting on the system. If those are too close to 100%, you won't be able to increase the transaction volume significantly without impacting the response time (which I assume is the most important metric).
After that, if you want to take a couple of statspack snapshots to look at the top waits, that would probably be a good idea. This will tend to show you where to focus your tuning if the stress test results are inadequate.

SQL connection errors when stress testing mobile service: SQL failure after 3 attempts
I have created a Mobile Service (node.js), which has been running for a few months with 50-100k api calls per day with no issues.
The usage of the service will be scaled up soon, and it will receive much higher traffic, so I am running stress tests (on a staging deployment of the same service).
The api in question queries data from the sql database that is attached to the mobile service, but caches the resulting data in a redis database for 5 minutes, so each call with identical parameters will not access the SQL database, just the redis cache.
My first test never has any problems:
Run a single api calls as fast as possible using the program wrk (https://github.com/wg/wrk). This test never has a problem, and I have run it an hour continuously with a sustained rate of 200 req/s and very few timeout errors.
The second test always causes problems:
I created a list of 5 different api calls to the same service (same endpoint, but different parameters), and I run those randomly interweaved as fast as possible. I use the program locust (http://locust.io) for this, spawing 10.000 clients at a rate of 500
per second. For the first few seconds everything goes ok, but then connections start failing massively.
I get mostly:
Error: SQL failure after 3 attempts. Error: [Microsoft][SQL Server Native Client 10.0]TCP Provider: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected
host has failed to respond.
(SqlState: 08001, Code: 10060)
And I see this in the http response:
ConnectionError(ProtocolError('Connection aborted.', gaierror(8, 'nodename nor servname provided, or not known')),)
The strange thing is that since I am running the same five calls repeatedly, only the very first of each call will actually access the sql database, every subsequent call will just return data directly from redis, and not try to access the sql database at
all.
In the azure console for the sql database in question, I see 1860 successful connections and 11 failed connections, which does not explain the massive failure rate I am seeing.Thanks for sharing your tips on this forum, as it will be useful for other users, that run into this issue.
Feedback like this will also help us improve error reporting in the next release, as missing class files in the packaged application is a common issue when developers are moving from the embeded oc4j instance packaged with JDewveloper to standalone instances.

For application that has many database read/write, is there any open source connection program that uses connection pooling?

Yes. the code works and the data set gets return when I execute the code. It only fail with stress test after say 150-160 hits.

Hello,
I want to perform stress tests on my Oracle 9i database. Is there a software that you can recommend to use. Maybe even scripts or shareware. Thank you.There are a variety of third party load test tools available, generally part of a suite of QA tools. You can also build your own test harnass.
99% of the work, however, is in figuring out what to run to put a representative stress on your application and, thus, your database. Figure out a representative number of OLTP users, a representative number of DSS users, an appropriate overlap in time and in data, etc.

Stress test Sharepoint 2013 portal. How and what do You use?
Hi!
I'm using example from here http://msdn.microsoft.com/en-us/library/jj710162.aspx
It creates record in SP task list. I can loop it to create several records. But how can I simulate
several users?
Or what in common sense do You use to stress test sharepoint? Any links or better there is a book?
Best regards,
Gennady
Разработчик под SharePoint, http://rockietm.wordpress.com, http://demo.arsenal-it.com>>You can use Visual Studio to create performance and stress testing projects.
Yes I know that I can use VS, it's in the link of my first post.
>>Check out my articles at:
Margriet, thank You very much! I see that You analyzed more than a hundred of tools and dived very deep into this question! Thank You for
the tool, it works for me!
1) But what You use to monitor server behavior, do You use Resource monitor? By example I can see some network and cpu activity during test, but how can I analyze this data..
or I'd use some video-capture tools(like 'camtasia studio'), record this system monitor and then analyze?
2) I understand correctly, that this tool covers "WFE test", mostly IIS, like pages generation; SQL database should be tested by other methods.
p.s.:Sorry for bad english)
upd.: added all Your counters, the picture looks impressive :-D

Hi,
i've perform a stress test of a database in 2 configuration :
1) Single instance 11.2 with 8gb Sga e 4gb Pga on Linux, 6core with instance caging =4, resource_manager=defaut_plan
2) 2 Nodes Rac 11.2 with 8gb Sga e 4gb Pga in both nodes on Linux, 32core with instance caging =4, resource_manager=defaut_plan
I've used Swingbench and the transaction per minute are equal, Avg transaction per s in rac are Greater then single instance (4ms vs 40ms).
I know that rac is not for high performance.
My question is: is rac config best than single instance and if yes what is the %?
Thank youHi SBHV,
As far as I know, if you choose to test Audio Conferencing, it will also simulate Video conferencing.
And the Key Health Indicators in Lync Server 2013 for your reference.

Weblogic server hangs during stress-testing -- possibly EJB deadlocks
Hi
While running stress tests on our application, our WLS 4.5.1 hangs even at a
mere load of 20 users. We are running on a Solaris machine. Database: Oracle
8.1.5, running on the same machine. Using oracle.jdbc.driver.OracleDriver as
the JDBC driver, and using JTS as the transaction manager.
When we did a thread dump (complete lis at the end of this post) and
basically we are seeing a bunch of our entity beans in a "locked" state. A
common pattern we see in the thread dumps is that
[1] weblogic.ejb.internal.BaseEJBContext.lock(BaseEJBContext.java:180)
[2] weblogic.ejb.internal.StatefulEJBCache.bind(StatefulEJBCache.java:250)
[3]
weblogic.ejb.internal.StatefulEJBObject.getContextForInvoke(StatefulEJBObjec
t.java:88)
[4] weblogic.ejb.internal.BaseEJBObject.preInvoke(BaseEJBObject.java:164)
[5] com.nps.ers.ejb.organization.<Our Entiy Bean>EOImpl.<a get
method>(ERSSystemConfigurationBeanEOImpl.java:1539)
[6] com.nps.ers.ejb.awardnomination.<Our entity bean>.<some method>
After more thorough studying of EJB transactions, we changed the isolation
level of all our beans from TRANSACTION_SERIALIZED to
TRANSACTION_READ_COMMITTED and made sure all our beans say TX_REQUIRED for
their transactionAttribue. Still, this problem persists.
The basic scenario we are load testing is that of multiple users logging
into the system and trying to access a particular user's record, and right
now, this is causing deadlocks at 20 users.
What we fail to understand is that --
(a) even if a method is attempting a read-only access to the data, why would
it try to obtain a lock? or why would it matter that the data is locked?
Some of the locks we are seeing are actually on a bean that is used for
read-only purposes.
(b) if 2 or more processes are trying to access the same record, based on
whichever process got their first, shouldn't one succeed, and the other go
into a 'waiting' state?
We have also opened this issue with weblogic support, and the response so
far has been that there "may" be a bug in weblogic 4.5.1 itself that's
causing it, and they need to look into it further. Other similar posts in
the newsgroup haven't been resolved either -- hence this general plea for
help. Please advise if you've any suggestions. Thanks
Sandeep

[4] weblogic.t3.srvr.ECan you post details on this instrumentation?
I know in the past when we ran into this type of problem, it took us a while
to think through and identify the problems.
Thanks,

Generally this indicates a deadlock in the order that you access your
entity beans. Please follow-up with [email protected]. There is
some instrumentation that you can turn on to help spot why this is
occurring.

Hi
While running stress tests on our application, our WLS 4.5.1 hangs even
at a
mere load of 20 users. We are running on a Solaris machine. Database:Oracle
8.1.5, running on the same machine. Usingoracle.jdbc.driver.OracleDriver as
the JDBC driver, and using JTS as the transaction manager.
When we did a thread dump (complete lis at the end of this post) and
basically we are seeing a bunch of our entity beans in a "locked" state.A
common pattern we see in the thread dumps is that

method>(ERSSystemConfigurationBeanEOImpl.java:1539)
[6] com.nps.ers.ejb.awardnomination.<Our entity bean>.<some method>
After more thorough studying of EJB transactions, we changed theisolation
level of all our beans from TRANSACTION_SERIALIZED to
TRANSACTION_READ_COMMITTED and made sure all our beans say TX_REQUIREDfor
their transactionAttribue. Still, this problem persists.
The basic scenario we are load testing is that of multiple users logging
into the system and trying to access a particular user's record, andright
now, this is causing deadlocks at 20 users.
What we fail to understand is that --
(a) even if a method is attempting a read-only access to the data, whywould
it try to obtain a lock? or why would it matter that the data is locked?
Some of the locks we are seeing are actually on a bean that is used for
read-only purposes.
(b) if 2 or more processes are trying to access the same record, basedon
whichever process got their first, shouldn't one succeed, and the othergo
into a 'waiting' state?
We have also opened this issue with weblogic support, and the responseso
far has been that there "may" be a bug in weblogic 4.5.1 itself that's
causing it, and they need to look into it further. Other similar postsin
the newsgroup haven't been resolved either -- hence this general pleafor
help. Please advise if you've any suggestions. Thanks

SwingBench an Oracle Stress Test and Benchmark tool
Last week I was in a RAC workshop hosted by Oracle.
In the workshop, Oracle using a tool called Swingbench to generate load for RAC testing. Which is pretty interesting and good tools.
Since I have seen quite a few inquiry regarding a good benchmarking and load generating tools. I thought it might be good idea to share it.
It's free and can be downloaded here.
http://www.dominicgiles.com/swingbench.html
Swingbench is a free load generator (and benchmarks) designed to stress test an Oracle database (9i or 10g)Hi,
To add to what yingkuan said, there is one more free stress testing tool called hammerora.

How to stress test VC 7.0 applications ?
Hello,
I'm a sap basis guy, our developers team will very soon deploy Visual Composer 7.0 applications on our Portal Production environnement.
I have been asked to to check whether the current portal configuration will be able to handle the additional worload ...
In my opinion, the only way to determine the impact on the portal of the iviews executed on the Visual composer Runtime is to perform a stress test.
I've proposed the Microsoft Web Application Server Tool to our developement team, but I've been answered that this tool can't help measuring user interaction
Apparently, the MWAS tool is just simulating user interaction with a web application by crafting POST and GET HTTP requests. On the other hand, the flash application doesnu2019t care about HTTP requests it is just a Flash Virtual Machine hosted by a single web page.
Unless we can emulate user interaction in the stress test, Ithe results of the tests will be meaningless.
Do you know any other way to measure user interaction and therefore to perform a relevant stress test ?
Thank you
Any help would be highly appreciated.
Best Regards.I've been answered by Marcel Salein on his blog : ask SAP for a GoLive check

Hello all. I am going to be running some tests on a standalone Tomcat 6 server which runs a couple of web apps i have written. I just wanted to ask for any advice on how to load/stress test, weather its and good software used, what to look out for or what the typical bottlenecks can be.
I understand every problem is different and unique but as this is my first time doing this i was looking for any helpful tips!

Thanks for any help given!You can check out open source options such as http://ripplet.sourceforge.net/ or a commercial offering such as HP's LoadRunner. Typical bottlenecks involve scarce resources (database connections, incoming sockets, file space, memory, threads, CPU. etc) It varies a lot. You certainly want some aspects of your application to handle high load (such as authenticating or re-authenticating a user, displaying layout and content other than the body of the page, etc.) After that, it really depends on your application.

PC powers off under Kombustor stress test MSI GTX 560-TI Twin Frozr II
Recently went through MSI RMA procedure and they replaced my 465 twin frozr II with the 560-TI twin frozr II. When the card is stressed under GPU Burn-IN benchmark settings, the computer will just reboot. Everything is set to stock speeds on the card.
I want to assume this is a power supply issue but I've had my i7 930 overclocked stably for a while, I reverted to stock speeds to give extra power back to the 12v rail, have unplugged my storage sata hd and dvd power and am still having this issue. Also it appears the 465 takes a lot more power than the 560-ti, though I hadn't stress tested it for quite a while.
My PSU is the OCZ500SXS. I monitored the 12v rail during stress testing and the lowest i see it drop to is 11.89v. Any ideas to narrow this down would be much appreciated. TIAUnderstood. Thanks much for the response. I'll replace the psu and run the same tests and see what happens. All this has lead me to be curious about how power is precisely drawn for the system. Is there a known good resource/article for getting a complete understanding here? Thanks.
Also, this appears to be a good deal, no? Especially the 750w version seems to get quite good reviews and I may do sli at some point so it would be a good idea to be prepared, right?

Performance (Stress Testing) Simulation For Requests
Hi GRC Gurus,
I am looking for a solution for performing a stress test (for performance) for change requests in Access Control. This should be a repeatable process in order to ascertain if there are any bottlenecks in the processing, memmory etc. In normal SAP, e-CATT was one of the simpler solutions - how about GRC Access Control ?
regards
Mushtaq MahmoodOnly one suggestion from experience (due to the multi-fold use of GRC AC).
Try to get 10 volunteers to aggressively submit and approve access requests, perform risk analysis and perform firefighter sessions, i.e. get a through User Acceptance Test performed to get a "as-real" feel of the performance-stress on the system.
At my current client, we have got around 10 volunteers each in the Europe, Americas and Asia offices and UAT is being performed over a 2 weeks cycle to really hammer the system, both to ensure the configuration is correct and working as expected and also to monitor the performance of the system over the global company network.
Basis team are monitoring the performance of the processes and DB usage.

Flash not working on latest safari 5.1.4
