I have configured 4 tomcat identical servers reached by a front server apache through mod_jk.

Regular percentages are: 1st:30% , 2nd:29%, 3rd:28, 4th:13% (note: lbfactor is the same for the 4 workers) What are therse percentages? I don't know which way I can scrutinize. I just can see a lot of errors within error.log: Error connecting to tomcat (not necessarily the 4th) or ajp_process_callback write failed. Not good.

Read about timeouts: http://tomcat.apache.org/connectors-doc/generic_howto/timeouts.html All attributes are listed on http://tomcat.apache.org/connectors-doc/reference/workers.html Do you have an how to for interpreting jkstatus ?

There's a bit of information on http://tomcat.apache.org/connectors-doc/reference/status.html or is there any other way, a kind of pure tomcat tool, to check the tomcat perfs.

Re: /context not working -- mod_jk error: no match for /server-status

One of the frustrations, and I dont know Apache well, is that the access log seldom updates. The error log in the same folder does update, but contains little information--apache restarts is about it. I don't know if this helps, but I just tried to access the sample web app from the server machine's own browser httpd://localhost/sample and I get Bad Gateway! The proxy server received an invalid response from an upstream server Error 502 locahost So that indicates, that Apache is answering via mod_jk (or mod_proxy). You should try the correct URL http://localhost/sample/ though. and this does update the access log. So you have a problem reaching your web server from outside. Firewall, DNS, routing or similar stuff.

Can you find your request in the access log? Go through all config files and find out, what is configured about /server-status. That URL doesn't have anything to do with mod_jk.

I expect someone has a monitoring tool running or a browser windows with auto-refresh for /server-status and that's what produces those debug log lines in mod_jk. No problem per se.

Rainer?). Not sure either :( Even if I looked at the code now, I wouldn't take it for granted, that the behaviour can't change. Agreed. I don't have a cluster handy to test, but it would be good to know what mod_jk actually does in the case where multiple JSESSIONID cookies exist and have different jvmRoute suffixes. Actually I'm not even sure what the browser is supposed to send (the same cookie multiple times, or only the one with the longest path match). My experience was that /both/ cookies were sent (which makes sense, since there's no prohibition against the same cookie name being used more than one time when a different path is used). OK, I did some (very little) work: RFC 2109 and 2965 both state: If multiple cookies satisfy the criteria above, they are ordered in the Cookie header such that those with more specific Path attributes precede those with less specific. Ordering with respect to other attributes (e.g., Domain) is unspecified. (sections 4.3.4 resp. 3.3.4). The code of mod_jk (1.2.28) looks for a URL encoded session id (and uses that one if it finds one) and otherwise it takes all cookie session ids it can find in the order of Cookie headers in the request. It then uses all the session ids in this order and searches for a usable worker (e.g. existing and not being in error or stopped) until it finds one or runs out of session ids.

The ChangeLog for Tomcat 4.1 can be found here: http://archive.apache.org/dist/tomcat/tomcat-4/v4.1.40/RELEASE-NOTES-4.1.txt It's not in the most easily-read format (changes are described by component, then by version, rather than the other way around, which is how I would have done it), but you still have to read it: look for every change between 4.1.24 (that's your current version, right?) and 4.1.40. You may have to read relevant bug reports, too. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkqFc9oACgkQ9CaO5/Lv0PAYhQCeJkuKdCkwd/UcQHxUh7/Zii8l KnIAoIClIURe/eRpAavc/HO2KtnkWhPc =KB5m -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org See the Web#39;s breaking stories, chosen by people like you.

detecting oracle connection failures
hi everyone, I'm having problems trying to combine Oracle and Tomcat: if I define a DB connection to a MySQL or Postgres resource, everything works fine and DB failures are properly detected. conversely, if I define an Oracle DataSource, apparently RDBMS or network problems are not detected and my application keeps waiting ad libitum, ignoring the maxWait parameter. my conf: Context Resource name=jdbc/myoracle auth=Container type=javax.sql.DataSource driverClassName=oracle.jdbc.OracleDriver url=jdbc:oracle:thin:@host:port:sid username=username password= maxActive=2 maxIdle=2 maxWait=2000/ !-- WatchedResourceWEB-INF/web.xml/WatchedResource -- /Context my environment: - apache-tomcat-6.0.20 - jdk-1.6.0_14 - ojdbc6.jar (2111220 bytes) is it a driver-specific issue? I couldn't find out any useful (i.e. pastable) hint. is tomcat+oracle such a rare combination? thanks in advance, roberto - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
tomcat web server optimization
Please consider the following details: Scenario: We put load on tomcat (basically a simple http request) and in response an http response sends 1 to show success. Executor and Connector configuration (TOMCAT 6) with java version 1.4.2: Executor name=tomcatThreadPool namePrefix=catalina-exec- maxThreads=300 minSpareThreads=100 maxIdleTime=12 / Connector executor=tomcatThreadPool port=8080 protocol=HTTP/1.1 acceptCount=100 acceptorThreadCount=2 processCache=-1 enableLookups=”false” connectionTimeout=12 socket.tcpNoDelay=true redirectPort=8443 / Now I have tried many other configurations but I think this basic configuration should work.What we eventually want is TPS around 1000.I have tried the version where we don’t use the executor and have useExecutor=”false” in connector settings and define maxthread and minspare thread count in connector.In all cases TPS seems pretty much the same. More so I have also tried using different protocol protocol=”org.apache.coyote.http11.HTTP11NioProtocol” as well. We have heap size increased to 1GB. Load Testing and results: 100 users hit once we get 23 tps at max 100 users hit thrice with no gap we get 250 tps. But as we go to increase the number of users and not iterations we get a bottleneck of 25 tps at max and not more.As minSpareThread count is 25 by default. I thought that it may very well explain the bottleneck but increasing the minsparethread count doesn’t help at all we get same results. What we want is a simple configuration that ensures high tps . I am stuck here would really appreciate your help.Would be waiting for your response.
Re: detecting oracle connection failures
I think you've misunderstood what maxWait does. It tells the pool how long to have your webapp code wait for a connection when all the connections in the pool are busy servicing other requests (the pool is exhausted). Sounds to me like you've successfully received a connection, are attempting a transaction and the transaction is hung up somehow with a potential network issue. I've not done any work with the Oracle drivers so maybe someone else on the list has an idea? --David Roberto Benedetti wrote: hi everyone, I'm having problems trying to combine Oracle and Tomcat: if I define a DB connection to a MySQL or Postgres resource, everything works fine and DB failures are properly detected. conversely, if I define an Oracle DataSource, apparently RDBMS or network problems are not detected and my application keeps waiting ad libitum, ignoring the maxWait parameter. my conf: Context Resource name=jdbc/myoracle auth=Container type=javax.sql.DataSource driverClassName=oracle.jdbc.OracleDriver url=jdbc:oracle:thin:@host:port:sid username=username password= maxActive=2 maxIdle=2 maxWait=2000/ !-- WatchedResourceWEB-INF/web.xml/WatchedResource -- /Context my environment: - apache-tomcat-6.0.20 - jdk-1.6.0_14 - ojdbc6.jar (2111220 bytes) is it a driver-specific issue?

You might want to try setting the testOnBorrow and validationQuery attributes for your connection pool. This will avoid DBCP giving out dead connections.

RE: Can't start Tomcat5 service on Windows Vista Home Premium
From: Mark Thomas [mailto:ma...@apache.org] Subject: Re: Can't start Tomcat5 service on Windows Vista Home Premium Maybe, maybe not. Looking again at the log message it does look more like a 64-bit issue rather than the JVM issue. The log shows that it's using a 32-bit JVM - C:\Program Files (x86) - so the default tomcat6.exe should work. I'd suggest downloading the .zip version and verify that Tomcat functions with the installed JVM, and only then trying to install the service with the service.bat script. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: Tomcat App Configuration
From: Markus Meyer [mailto:me...@mesw.de] Subject: Re: Tomcat App Configuration sorry if I got that one wrong. It's just that it works for me the way I describe it. I doubt it. Not only are you violating standard practice by putting a Context element in server.xml, your path attribute is wrong: the default webapp is , not /. Whatever happens to be working in your environment is an accident. I would not put the app into /usr/share/tomcat5.5/webapps because this is the default location. ??? That makes no sense at all. Using the default location makes thing easier. To the OP: ignore Markus' very poor recommendation, and just rename your webapp to ROOT, as David suggested. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: Realm configuration issues
From: Adam Posner [mailto:cuco2...@gmail.com] Subject: Re: Realm configuration issues I tried commented out everything between the context tags in server.xml and put it in context.xml like this: What context.xml? Be specific as to the location. It broke it; I got a parse error(NullPointerException) in context.xml line 21. I don't see anything in particular wrong with what you posted; is that an exact copy paste, or is it subject to transcription errors? This brings me to the question about the resource element. Where should that be put ? As the documentation for DataSourceRealm states, you may place the Resource inside the Context element, as long as you set the localDataSource attribute for the Realm to true. Do I still need that Resource element above to be defined somewhere, Yes - the Realm needs to use it. resource-ref descriptionDB Connection/description res-ref-namejdbc/trailsDB/res-ref-name res-typejavax.sql.DataSource/res-type res-authContainer/res-auth /resource-ref The resource-ref shouldn't be used, since it's the Realm that needs the JDBC connection, not your webapp. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

How do I know how many threads are being used during a test run (both tomcat and apache)? We used to have some tools for that but not currently in the new environment.

Re: Realm configuration issues
Yes, that was an exact copy and paste. Here it is again - of my
META-INF/context.xml, before I deleted it and put it back in server.xml :

It throws a NullPointerException due to a parse error in context.xml:

I'm using the editor Kate; I dont see any extra tabs or spaces in
the wrong places, Kate has syntax highlighting so I would see that anyway.
But it does work (up to the authentication part) when I put everything from
my META-INF/context.xml into a context element in server.xml:
Context path=/blurbV1 docBase=blurbV1 reloadable=true
!--
9/6 ?user=buzzamp;password=99 maxActive=8:
Removing this from the line below gave me an
'access denied for user @ localhost (HTTP 500),
using password .. no'; it only works for user buzz,
not user cuco; (get the same error, but ('..using password .. yes'

Note that I need to enter everything after the '?' above, I can't just put
up to the 'trailsDB' part of the url attribute.
Anyway, here's a copy and paste of catalina.out with the configuration of
the Realm in server.xml, which is the closest I can get to having it work:
