config help
Hi - I am currently in the process of deploying a web app using Tomcat 4.1.18, MySQL 3.23 on a Win2K Server. The app will be used heavily for a period of 3 - 4 hours, (probably a couple of thousand hits per minute), then never used again. I am wondering what exactly I should do to enhance performace - other than some changes recommended to the server.xml file (i.e. setting debug to zero), I am not 100% sure what some of the other changes will do, specifically min and max processors, and other settings. Can someone please give me some pointers as to what I can so to maximize performance over this 3-4 hour period?? Application is a series of MySQL based reports (all servlets), containing several select statements and using the MySQL JDBC driver. Thanks for any advice!

RE: config help
Thanks - I am plugging through that now. Another question - if I use the following as
a basic connection creator / counter:
public static void main (String[] args) {
try{
for (int i = 0; i 1; i++){
Class.forName(org.gjt.mm.mysql.Driver);
con =
DriverManager.getConnection(jdbc:mysql://MYIPADDRESS/DBNAME?autoReconnect=true,user,pass);
System.out.println(Got connection: + i );
}
}
catch(SQLException se){
System.out.println (SQL Error: + se.getMessage());
}
catch(ClassNotFoundException cnfe){
System.out.println(Class Not Found Exception: +
cnfe.getMessage());
}
}
What exactly does this do? Is it leaving connections open and then gc'ing them
whenever it wants? I assume because I am not closing them anywhere that they are not
being instantly destroyed.

It sounds as if you are indeed opening/closing
connections as you need them.
You need to configure a datasource for your db
connections:
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-howto.html
Its fairly easy to set up and the gain is significant.
I would say it is probably a good practice to use this
anyway, even if you do not expect heavy traffic.

RE: config help
I guess my confusion arises from lack of complete understanding of what is going on. So, does Concurrent Users differ from requests? If a connection is opened in the init() method, and closed in the destroy method, would that not mean that the concurrency only applies to the amount of time needed to instantiate, create, use to get data and then destroy? After the page has been requested and passed to the browser, wouldn't the connection be available for gc immediately? So if I am assuming 2000 - 3000 users accessing the information over the same time frame (3 - 4 hours), what would be the estimate of required concurrent users? Does that mean simultaneous HTTP / JDBC requests?? Thanks..

Weird occurrence - thoughts??
Ok here is a new one to me - on my dev box (WIn 2K server, Tomcat 4.1.18), plugging along this morning, not working with config files at all, when I get the servlet not available message, on servlets and .html pages. Can't start anything from the manager, Tomcat will restart, but still cannot seem to find applications running minutes ago. Haven't touched the JAR files in weeks, everything has been running smoothly. Got this in my localhost output log.

Slightly OT: SocketException with MySQL
I am using Tomcat 4.1.18, MySQL 3.23, newest driver, running on Linux 7.3. Problem is similar to others who have posted on this subject, just want some advice (can't seem to get a definite answer). I'm not using connection pooling. If I walk away and leave the server running for several hours, I come back and cannot access the database via the servlet, the catalina.out file tells me SQL Error: Communication link failure: java.net.SocketException. Happens whether or not I am running TOmcat remotely on or the same box as MySQL (i.e. not a network issue). I made sure all of my connection objects were close in the destroy() method of each servlet thinking all of the sockets were full, still didn't work. I just recently set autoReconnect = true in my server.xml realm tag - that doesn't seem to make a difference. Should that work? Or, should I be closing the connection object IMMEDIATELY after each executeUpdate or executeQuery? Currently am opening a connection in the init() method, and killing in the destroy(). Any suggestions greatly appreciated!! Thanks, Geoff - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Server.xml
Sandra - I have had similar experiences with similar frustrating results, and it always seems to be placement of the Context /Context tags - for some reason sometimes you need closing /Context tags, other times you don't, I can't seem to figure out when to use them and when not to, so I end up fiddling around with various combinations until Tomcat starts! (that was a really dumb answer but it works for me) Geoff -Original Message- From: Hunter, Sandra [mailto:[EMAIL PROTECTED] Sent: Monday, March 17, 2003 5:00 PM To: 'Tomcat Users List' Subject: Server.xml Frustration abounds: I am plodding through a tomcat tutorial and it suggests modifying the Server.xml file to include a new context path line to allow for playing with a sample file. Everything works tickety boo until I do that, then Tomcat won't startup at all. When I enter the startup command I just get a really brief flash of screen and poof! It's gone again. When I take the new line out of the server.xml file the problem persists: poof! Gone. That is the only change I make.

context-param
Yoav (or anyone else that can help me) - I made the changes to my web.xml file as recommended. Two questions: 1) do I need a seperate context-param tag for each context parameter, or can I put them all in the same block? 2) where is the best place to call getServletContext().getInitParameter(driver) within a servlet? In the init() method? Or on the fly, for example at the start of the doGet() method? Thanks again, I appreciate the help!!

RE: servlet with Tomcat
Nicola - Read the thread from yesterday with the titles Can't find servlet - I had the exact same problem, it has to do with the invoker servlet - you need to add specific mappings in your web.xml file for each servlet, and disable the mappings for the invoker servlet under /conf/web.xml, it is a security fix from 4.1 and up I believe...

System administrators of my department installed J2SDK 1.4.1 and Tomcat 4.1.18 in a local machine. After that I have setted the enviroment variables CATALINA_HOME to the install_dir of Tomcat and JAVA_HOME to the install_dir of J2SDK1.4.1 classes. Then I can start Tomcat using the script $CATALINA_HOME/bin/startup.sh (it is a Linux machine) and I can see the local home page $CATALINA_HOME/webapp/ROOT/index.html browsing http://localhost:8080/ . I can see aslo the example servlets situated at $CATALINA_HOME/webapp/examples/WEB-INF/classes/ browsing http://localhost:8080/examples/servlet/ServletName but I cannot see servlets situated in the usual work directory $CATALINA_HOME/webapp/ROOT/WEB-INF/classes browsing http://localhost:8080/servlet/ServletName (I'm just a beginner of JSP technology and this is what I found in a JSP manual that I should do). I mean that if I create any my servlet file called MyServlet.class and I put it in the directory $CATALINA_HOME/webapp/examples/WEB-INF/classes/ I can see it, but I canno see it If I put it in the directory $CATALINA_HOME/webapp/ROOT/WEB-INF/classes. I can also tell you that I can see any html page situated at $CATALINA_HOME/webapp/ROOT/MyPage.html browsing http://localhost:8080/MyPage.html Do you think this is a problem of configuration of Tomcat?

tomcat manager question
I recently upgraded from 4.0.2 to 4.1.18 on a development box running Windows 2K server. I am in the process of migrating some applications to this version of Tomcat, also to jdsk 1.4.1_01. Got everything up and running with one small problem related to the manager interface. I have the following context in my server.xml file: !-- IfaxSend Context -- Context path=/IfaxSend docBase=IfaxSend debug=0 reloadable=true crossContext=true / Realm className=org.apache.catalina.realm.JDBCRealm debug=5 driverName=sun.jdbc.odbc.JdbcOdbcDriver connectionURL=jdbc:odbc:replixdb userTable=Users userNameCol=FaxUserId userCredCol=PIN userRoleTable=Users roleNameCol=UserRole / Logger className=org.apache.catalina.logger.FileLogger prefix=iFax_IfaxSend_log. suffix=.txt timestamp=true / Which works fine. The problem is that when I include this context, the authorization for manager application seems to try to authenticate against the context level JDBC realm (application level), instead of the Realm className=org.apache.catalina.realm.MemoryRealm / tomcat-users.xml file that it normally uses (this realm tag is just below the engine tag, at the global level. what could be causing the global level realm to be overridden at a lower level? Shouldn't a context level realm only relate to the application within the context?

RE: Opinions of available Tomcat books
Bill - I recently purchased Mastering Tomcat Development (Wiley)by Peter Harrison and Ian McFarland, and Professional Apache Tomcat - WROX (9 authors). The Goodwill book was the first one I purchased, and it was good for initial setup and basic application deployment, however as Subir said once you get into anything difficult it is kind of useless. Out of the other two, I would recommend the Wiley book, excellent reference, but there are things covered in Wrox that aren't in Wiley - I am at a junior - intermediate developer level in Java, and I find both worth the money.

Some sidenotes to your source code:
- You shouldn't open a connection in the init method.
This way you share one connection between two concurent requests to
the same servlet.
It's better to use a connection pool and get the connection for every
request.
- All your instance variables are dangerous, because they are shared
between
two concurrent requests to the same servlet.
- Maybe you should use Throwable instead of Exception
try {
} catch {Throwable ex}
}
This way you will have also control about the Errors that might occur.

Not sure (haven't done it) - but that sounds like standard folder security issue, just set up a user or user group with the User Manager in windows, and change folder permissions on the server, but as far as making NT security mesh with Tomcat, I am unfamiliar with that - Tomcat uses the windows authentication in its own way (to authenticate against the tomcat-users.xml or the database defined in the realm), but integrating it with folder permissions - maybe someone else has done this?

Problem occurred today when a user viewed the results of a SQL query in their browser, changes that were reflected in the database were not reflected in the SQL query (i.e. all records prior to May 1, 2002 were returned, all records since May 1, 2002 were not returned) - I tested and retested my SQL code in the database and it returned the proper number of records, just not through the application. I stopped and re started TOmcat and the problem was fixed, the correct amount of records were returned. Something to do with the connection string? As I mentioned I am using an ODBC driver in my config file.
