Connection pooling issue on Tomcat
Hi folks, I'm using Tomcat 6.0.29 for an app I've had in place for years. I run the Java app I have on a Windows 2003 server for my production region, but have local builds on both my desktop and laptop, both of which are Windows XP Pro. Yes, I do realize that the Tomcat version is old, but we'll be retiring the app in a few months so there's no need (at this time) to upgrade it. I use connection pooling, specifically Tomcat's DBCP class. This app has worked for years, but is suddenly encountering a strange connection error and issue to the PROD region only of Oracle 11. This just started in the last week. I'll include the contents of my context XML file and the errors that it's generating. Even stranger, my development build to the Oracle UAT region works just fine! These content.xml files are virtually the same, except one references the Oracle PROD region, and the other references the Oracle UAT region. The Resource name attributes vary really only slightly, one called myoracle, the other called myoracledev. Context Resource auth=Container description=changectrlapp name=jdbc/myoracle type=javax.sql.DataSource driverClassName=oracle.jdbc.driver.OracleDriver username=username password=password url=jdbc:oracle:thin:@servername.dom.net:1648:SVCNAME maxIdle=30 maxWait=1 maxActive=20 testOnBorrow=true timeBetweenEvictionRunsMillis=-1 minEvictableIdleTimeMillis=28800 poolPreparedStatements=true removeAbandoned=true removeAbandonedTimeout=300 logAbandoned=false/ The errors I am getting are: javax.servlet.ServletException: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (ORA-01033: ORACLE initialization or shutdown in progress org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (ORA-01033: ORACLE initialization or shutdown in progress java.sql.SQLRecoverableException: ORA-01033: ORACLE initialization or shutdown in progress This may not be much to go on. But like I said, with attributes only slightly different, the connection to UAT works. By the way, I am connecting successfully to the Oracle PROD DB through other avenues: TOAD,SQL Plus, MS Access, etc. So the DB itself is working. Both my DEV/UAT and PROD regions use the same DBCP classes. Could something have gotten corrupted for one and not the other? Any feedback is welcomed. Let me know, please, if I neglected to add anything pertinent to this.

My apologies in advance for some of the syntax and verbiage - I am a newbie
in all of this, but did do my reading / research / and chat on IRC's.
The current setup I have is this:
Apache DS LDAP version 2.0.0-M14 running on Linux with Port 8660. The
server instance works fine and I am able to do a search via Apache API in
Java (Eclipse). I bind to this server anonymously via connection.bind()
Tomcat version 7.0.47 running on Mac OS X (Maverick) with Port 8080. The
Tomcat instance work fine using the installed default values. I am able to
run simple REST API and consume them via any browser.
Issue: I am trying to create a connection to the LDAP server via anonymous
binding. I configured the appropriate conf file: server.xml with the REALM as
follows:
Realm className=org.apache.catalina.realm.JNDIRealm
connectionURL=ldap://Integration01.icsl.net:8660;
debug=99
userBase=dc=sumsmail,dc=com
userSearch=(mail{0})
userSearch=(userCertificate{0})
Why do you have userSearch specified twice? That's what's causing the
exception below.
userSubtree=true
roleBase=dc=sumsmail,dc=com
roleName=cn
roleSearch=(mail={0})
roleSearch=(userCertificate={0})
This will likely cause a similar exception, you can only specify these
attributes one.
Dan
roleSubtree=true
/
/Realm
Host name=localhost appBase=webapps
unpackWARs=true autoDeploy=true
Not that I'm particularly knowledgeable about configuring LDAP, because I'm not
but looking at the error I wondered what Dan did - why did you have the
userSearch attribute listed twice? You also have the roleSearch attribute
listed twice, though it might not show that error since it spits up at the
first one.

I'm going to go ahead and echo the few responses you're already gotten so far and tell you that you really need to discard that version of Tomcat. I don't care if you have an application that works on it (obviously in some other environment) and are afraid to upgrade. That version is so old, we don't even have the documentation online anymore for how many unfixed security vulnerabilities may or may not be present in that version. The Java Servlet Specification is nominally backward-compatible, so you should be able to download the latest version of Tomcat, configure it properly, and run your webapp without too many problems. I can run simple jsp programs with no database connection. But whenever I try to execute programs with database connections, following error encounters: Error: 500 Internal Servlet Error: javax.servlet.ServletException: [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application at [...] The error is obvious from this message, but if you don't recognize the important words (architecture mismatch) then you could be lost. The problem is that you are using a 32-bit ODBC driver on a 64-bit JVM (or maybe a 64-bit ODBC driver on a 32-bit JVM: you didn't specify what kind of JVM you were using, though I suspect you have a 64-bit JVM and a hideously old driver that you've been lugging-around with your Tomcat 3 install). You need to take one of the following actions: 1. Install a 32-bit JVM and use that. This will solve the architecture mismatch by switching the JVM. This may have an impact on your webapp (mostly a smaller maximum heap size) so you may not want to do this. 2. Install a 32-bit version of your ODBC driver and use that. This will solve the architecture mismatch by switching the driver. You may not be able to find a compatible 64-bit driver so you may not be able to do this. 3. Discard your ODBC driver entirely and use a pure-Java JDBC driver. Pretty much every database has one of these things available one way or another. This avoids the architecture mismatch entirely and it will likely result in better performance and stability of your web application. I highly recommend that you take this course of action. What database are you using? Please do reply or help me with this problem as I tried so many times to fix the problem by trying various solutions. In the future, it would be best to let everyone know what solutions you have tried and what the results were (other than just it didn't work). - -chris -BEGIN PGP SIGNATURE- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJRkRG6AAoJEBzwKT+lPKRYaaoQAJyFeYHGRmZomqFan7W2jdHv u7TZwFKlLAfkMfJaQQibprnuLZpW4flC5gdM0Rbj14EtfDauEMCSfe++oo6YlvqQ F0Mih9ReRt7wSxVLNG58hUqcM6Hg3evEtwWoq9yd5I9YHYdl8Cz0X035/tdUHOUz 2RKBqQbFKr3A8m1k6Q6IYjsRKvPFDwyu0ekRYMrvSdtFZkiYPvzzwW1FpXdQ0Rwh mHmVPrZzoIjiVXLWzT+kfFfrdrK6yBopieYZvOufEei88ZRvaI6u5LrXEpN6GEhX DNkFoDWjPYXuKdQS+JBdwFX16DIKl7nIqI5nZ2sZthjPVqK64+r26R5tp+WEX5rp ADkKyb6iGnwpAxy6l4LBGdanpDug0hC2beeOUtmcQkujJoychlvvF5L69VGpeEU1 JSQR0bQJGJIF9rP/PyAjBLzAUSI9sqh8IUZ+Bm+JrpAgiAWNSmKzeCW2te5r/GcF Nt5ZpKBqMC2UHPNMRxKjIfuGc0gTApX467tVQ5zaouNbWO/lSOMrhZCgF8SD/OcF fiQGrfeCDirHKIR6sczu3r07fGShTNCA47svAFV3/K31ou5dZT6SM3IvVqo2ZXog whHWIXLxGl9SZrJToAJYcjlR2nRSb/yKygiE9Z2csgt34fUj9vQmWFo93ueph+j1 p8A0RhUfe4Kx6KzJ5lmP =LZlk -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

RE: JNDI setup oracle 11 g
Tony,
I have a similar standalone Java app that hits Oracle 11g.
At your line with the DBURL, I have something much more concise.
Where you have
public static final String DBURL = jdbc:oracle:thin:@(DESCRIPTION = (ADDRESS =
(PROTOCOL = TCP)(HOST = abc-def-scan.corp.xyz.com)(PORT = 1521)) (CONNECT_DATA
= (SERVER = DEDICATED) (SERVICE_NAME = SAMPLE.WORLD) ) );
I simply have:
String dbURL = jdbc:oracle:thin:@dbservername.1526:servicename;
I set the rest of that string in my tnsnames.ora file - not sure if you're
unable to do this or not. I'd think you'd do it there.
Could that be where the error is stemming from?
The rest of it looks correct to me.

RE: JNDI setup oracle 11 g
I might add, Tony, one other thing I noticed in my JNDI config.
I'd removed the validationQuery attribute. It might have been regarding this,
but I'd writtten a comment right below it that per Konstantin, there was a
memory leak regarding the Eviction Timer.
Try removing that attribute (validationQuery = SELECT 1 FROM DUAL) and
running it -

Thanks Barry,
The reason for the long dburl string is that this is an Oracle RAC (Clustered
database). My understanding is that the simple dburl cannot be used for RAC
databases.
Also, I tried removing/adding the validationQuery from the context.xml,
however that did not work either :(.
When I researched the ORA-00911 error, it typically is thrown when you haven an
invalid character in the query. However I get this error when trying to get a
connection via the JNDI reference to the pool.
The strange thing is that this works via a simple java program that directly
uses the JDBC/Oracle driver.
I can work around the issue by not using JNDI in the web app, however I am not
then able to use pooling I guess.

My SSO (old JOSSO version) works only with 6.0.18. How are you determining this? Are you looking at open connections from your database? Are you looking at JMX stats for the connection pool? I'm using JavaMelody monitoring system. Can you verify this through your database? Perhaps the monitoring tool is not showing the correct information? These don't really seem to be indicating any sort of problem. The first looks like it is reading data from a socket, the second is simply waiting for something to do. Yes, but why there are 50 open old (some almost a month) DB connections (and still raising) on low traffic app? This sounds like an application issue. Check to make sure it is not storing connections retrieved from the connection pool and check to make sure that you are properly closing connection (i.e. correctly using try..catch..finally). If possible, maybe run FindBugs. That's a good way to catch errors like these. That is strange. There should be some parameter to auto close old connections. I have tried tunning many parameters, but without success. Can't really say with OracleDataSource. With DBCP there is removeAbandoned / removeAbandonedTimeout / logAbandoned which can be used to reclaim connections that have been held by the application for too long. This looks fairly normal with the exception that you are using an OracleDataSource. Not sure how much this list will be able to help you if the problem is with the connection pool. You'd probably need to contact Oracle. I was using DBCP, but I couldn't cast in my Java servlet code from DBCP to OracleConnection once when I get DBCP datasource from JNDI (getInnerConnection() also didn't helped), so I swithced from DBCP to OracleDataSource. The documentation for DBCP say to do this... 1.) Set accessToUnderlyingConnectionAllowed to true (it defaults to false) 2.) Use this construct to get the connection. Do NOT close the underlying connection, only the original one! Connection conn = ds.getConnection(); Connection dconn = ((DelegatingConnection) conn).getInnermostDelegate(); ... conn.close() https://commons.apache.org/dbcp/configuration.html I have not done this though, so I cannot be sure it will work for you.

My network people tell me that all ports are open to me and when they try to capture packets coming from me, they see nothing if I'm starting up my tomcat. I'm not a Network or VPN expert, but as far as I know, at the application level it should behave just as if I'm connected directly to the network and shouldn't have to worry about which network adapter to use (built in or VPN), and shouldn't have to worry about routing.

Perhaps a network issue is causing them to be disconnected or the database may be timing them out. At any rate, it's not likely that the problem would be caused by the removeAbandoned / abandonedTimeout settings, unless you application is not properly returning connections to the connection pool. https://tomcat.apache.org/tomcat-7.0-doc/jndi-datasource-examples-howto.html#Preventing_database_connection_pool_leaks (for a web application). And the only way to get the connections to work again is to restart tomcat. My tomcat.jdbc.pool.Datasource settings have: property name=maxActive value=100/ property name=maxIdle value=30/ property name=maxWait value=1000/ property name=defaultAutoCommit value=true/ property name=removeAbandoned value=true/ property name=removeAbandonedTimeout value=60/ You probably want to add testOnBorrow=true and validationQuery=SELECT 1 (or some other valid query for your DB). See the following link for an explanation of those properties. https://commons.apache.org/dbcp/configuration.html This will cause your connections to be validated prior to their use by your application. Stale connections will be removed and replaced with new, working connections. Is it the removedAbonded and abandonedTimeout? Does it mean after 60 seconds, remove the connection from the pool? No. See either of the links I've referenced above for an explanation of these settings. I guess what I need is a minActive setting then? There's no minActive setting.

Barry -Original Message- From: Jeffrey Janner [mailto:jeffrey.jan...@polydyne.com] Sent: Tuesday, October 25, 2011 8:52 AM To: 'Tomcat Users List' Subject: RE: ODBC jar files Barry - I run an Oracle mixed environment and I can assure you that you will run into problems running ojdbc14.jar and connecting to your 11g database. In particular, you will see some odd errors related to bind peek on the server side - but that is supposedly fixed in 11.2.0.2. I can't say for sure as I haven't been able to schedule an upgrade, yet. If you want to talk to 11g, you really should use the 11.2.0.2 ojdbc jar file. You can get that directly from the Oracle website. It should be mostly backwards compatible for connecting to 10g, but there are a few improvements that might come back to bite you. In particular, they have added additional mappings to handle the Native Language string columns (NCHAR, NVARCHAR, etc.). Before switching to that jar in your legacy app, you need to insure that it won't be a problem, or you may need to make some quick changes to the code. Also, according to Oracle, make sure you grab the ojdbc file that matches the Java version you are running. If your Tomcat runs under Java 5, you need the ojdbc5.jar. The ojdbc6.jar is only for using with Java 6. They are the same code, but compiled for those java versions, and I assume optimized for them. If you don't know what version of the ojdbc file you have, you can always look it up. Using your favorite unzip tool, extract the MANIFEST.MF file from the META-INF directory of the ojdbcx.jar file. It's a simple text file and contains the release number of the jar file. And while you're on the Oracle JDBC website, download the documentation that goes along with it. Read it thoroughly and see what other changes they've made that might be useful and/or detrimental to your implementation.

ODBC jar files
Question. Will it hurt to have two different odbc jar files in the lib folder? I've been connecting to a production server on Oracle10g for some time, and have had my context.xml file in the META-INF directory of one web app configured to hit this Oracle server. Our group just got a new development server on Oracle11g, and while I can connect to it via Toad or SQL Plus (thereby assuring the tnsnames file is properly configured) I cannot connect at all from the web app in Tomcat. I've been using the drivers in the ojdbc14_g.jar file for some time but I think I may need ojdbc6.jar for the new Oracle server. I wasn't sure if these two would conflict or not. FWIW, I'm using: Tomcat Version 6.0.26 JDK 1.6.0_18 Win XP is my OS for the test machine. The above mentioned .jar files. I just added the second one, ojdbc6.jar, then deleted the work folder contents and restarted the web app. My context.xml file is configured in the following manner: -- Context Resource auth=Container description=changectrlappdev name=jdbc/myoracledev type=javax.sql.DataSource driverClassName=oracle.jdbc.driver.OracleDriver username=usernm password=password url=jdbc:oracle:thin:@croesm6734:2504:LANDMVJ maxIdle=30 maxWait=1 maxActive=10 testOnBorrow=true timeBetweenEvictionRunsMillis=-1 minEvictableIdleTimeMillis=28800 poolPreparedStatements=true removeAbandoned=true removeAbandonedTimeout=300 logAbandoned=false/ Realm className=org.apache.catalina.realm.DataSourceRealm localDataSource=true dataSourceName=jdbc/myoracledev userTable=users userNameCol=user_name userCredCol=user_pass userRoleTable=user_roles roleNameCol=role_name/!--using -- /Context I've also tried the following: -- Context Resource auth=Container description=changectrlappdev name=jdbc/myoracledev type=javax.sql.DataSource driverClassName=oracle.jdbc.driver.OracleDriver username=usernm password=password url=jdbc:oracle:thin:@(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = IPC )(KEY = LANDMVJ)) (ADDRESS = (PROTOCOL = TCP )(HOST = croesm6734.specserver.net)(PORT = 2504))) (CONNECT_DATA = (SID = OPSDEV) (SERVICE_NAME = LANDMVJ) maxIdle=30 maxWait=1 maxActive=10 testOnBorrow=true timeBetweenEvictionRunsMillis=-1 minEvictableIdleTimeMillis=28800 poolPreparedStatements=true removeAbandoned=true removeAbandonedTimeout=300 logAbandoned=false/ Realm className=org.apache.catalina.realm.DataSourceRealm localDataSource=true dataSourceName=jdbc/myoracledev userTable=users userNameCol=user_name userCredCol=user_pass userRoleTable=user_roles roleNameCol=role_name/ /Context -- with the same error message getting logged.

Odd to use a local variable for this, but I guess you could do that.
I've seen java:comp/env and java:/comp/env, but both seem to work.
Try running this JSP. It's a bit fragile, but it should get the job done.

It might be helpful to know if you deleted items out of your work directory or if you are implying you have to leave cached JSPs there without touching them, but you altered something else?

RE: Working of Tomcat with MS Access
Jeff has some really good points here, Rahul.
I'm a guy who spent several years doing ASP development with both MS Access and
SQL Server over the web before getting into Java.
Even still, I didn't fathom trying to mess with MS Access with Java when I was
making that transition. I started with mySQL on my Windows desktop to get
started, but when I got access to our Oracle servers, went that route.
Like Jeff says, you can do this basically for no cost using both Tomcat and
mySQL.
Sure, it's command line, unlike MS Access, but you shouldn't have too much
trouble with it. Jeff, if he's using MS Access, he's probably not on Linux, is
he?

IMHO MS Access is not and never has been useful as a professional
database product. I'm not even sure if what you are proposing even
holds up in the looking-through-binoculars-from-the-big-end sense.
MS Access is a desktop application that accesses files on disk. Java
apps running on Tomcat typically access an RDBMS over a network
connection via SQL statements and their responses. AFAIK there is
not a server instantiation of MS Access; in fact, part of the whole
point of MS Access as an ongoing product is that it acts as a
gateway drug to MS' SQL Server product, the transition to which
would be triggered by the inherent limitations (and, in my past
experience, persistent unaddressed bugs) of Access.
I think you need to back up a bit and work toward getting your data
liberated from MS Access and ported into a proper RDBMS like
PostgreSQL or one of MS SQL Server, Oracle, IBM DB2, etc. if you feel
that money must be continually spent on software licenses for such.
Then you will be facing Java apps and Tomcat in a far more conventional way.
So, to sum up this and earlier responses: 1) Learn to code Java 2)
Understand real RDBMSses.

Hello Tomcat community,
I'm again experiencing an oddity with the manager app.
I'm using Tomcat 6.0.26 on Win XP Pro, and JDK 1.6.0_18. Hope I included
everything here that's needed.
I'm not getting an error generated to the logs out of this, just the generic
requested resource (/manager/status) is not available. message in the
browser window.
My first guess would be that the manager app is not running.
I've since taken the address off entirely, tried the new IP address, all the
while deleting the manager contents (and sub dir, too) out of the work
folder, deleting the manager.xml file out of the conf/Catalina/localhost
directory, after having stopped Tomcat and prior to a restart.
I guess that maybe your manager.xml or
webapps/manager/META-INF/context.xml is broken (like a typo somewhere: a
stray '' or a nested comment ('--' is not allowed inside comments)). There
should be errors logged somewhere.

RE: tomcat issue with DBCP connection pool
And to thisis it absolutely necessary to use the SYS_REFCURSOR in Oracle? I use several packages and procesures and never use this! Granted, I may have many less records than you in your DB table, but I was just wondering. Perhaps it is. BTW, my application calls a stored procedure which in turn uses an oracle SYS_REFCURSOR. As I know ref cursor can not be closed through code. How are you supposed to close that cursor, then? Did you mean you can't close it through Java code, or you can't even close it through PL/SQL? Once the error is encountered the application is not recovering until the application is restarted. Sounds like closing the connection and re-initializing it would probably do the job, too. Is it possible for you to detect the kinds of requests that will allocate these SYS_REFCURSORs and use a one-time connection instead of going through the pool? - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk2HYRkACgkQ9CaO5/Lv0PAOpQCfWY5OKJoRo1C8Ld//bOTpCC3x t/QAn2qdGxo0uXDU01rf6A+IElsrLDTq =40df -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Issue is I'm trying to alter the context.xml file within the manager webapp folder, for an IP restriction with the RemoteAddrValve, like so. In webapps/manager/META-INF/context.xml: !-- Valve added to prevent access to this webapp from public computers -- Context antiResourceLocking=false debug=0 privileged=true Valve className=org.apache.catalina.valves.RemoteAddrValve allow=100\.111\.111\.23 / /Context In trying to overwrite the current setting to allow for the filter, do I need to delete the manager.xml file in Tomcat\conf\Catalina\localhost ? Doing so doesn't allow the manager.xml file to be recreated, upon starting and stopping the Tomcat service, unlike other webapp context.xml files. Shouldn't it do so? My other context.xml file (from tomcat\webapps\webapp1\META-INF\context.xml recreates webapp1.xml file in the Catalina\localhost folder upon being deleted, and then restarting the service. But not the manager.xml file. Please advise to if I'm doing something incorrectly here or need to supply more information. Thanks, Barry - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
RE: Tomcat manager
Ok, so it ( webapps/manager/META-INF/context.xml) doesn't necessarily get copied out to the Catalina folder then? Is that correct? I mean, upon stopping the Tomcat service, and restarting it? Am I understanding that correctly? I hope I'm understanding you correctly.

RE: clear text keystore password in server.xml
I was told by my company we're not supposed to have passwords stored in clear text. I explained to them the architecture of Tomcat, and didn't get a clear answer on whether or not it's ok, though I think it is. I don't know what kind of DB you're using, Vijay, but the Oracle DBA told me he could open the wallet, I could reference in my server.xml file the OCI driver reference instead of thin driver, and omit using the password, as it would be encrypted in the DB column, then decrypted when called. I have not yet tried this out, but am thinking about going down that road. What DB are you using, and is this an option for you? -Original Message- From: Vijay [mailto:amirisetty.vijayaragha...@gmail.com] Sent: Friday, August 27, 2010 7:20 AM To: Tomcat Users List Subject: Re: clear text keystore password in server.xml Hi Mark, I guess I am getting the point you are trying to make ..

RE: DB configuration and socket error
Yeah, sorry, Chris...it probably is moreso Oracle related in nature than Tomcat. I just thought I'd make sure about that before I addressed it with the one set of Oracle personnel in the midwest location. I'm hardly an Oracle expert, but the only difference to my knowledge on these two different servers is that one is on an HP Solaris and the other running on an IBM AIX, I think it is. They have different types of auditing software, but nothing that should specifically inhibit connectivity like this. I'll try to address it on Oracle's forum and see if anyone can shed light on the 12505 error.

RE: DB configuration and socket error
BTW, Chris, I did happen to be calling DriverManager.getConnection() passing the user/pwd params -- in this instance. And 12505, according to the Oracle forums, seems to be some kind of listener problem. I had reckoned that the problem might be with their (the midwest center's) Oracle server's ports, and what its server would allow, or be listening to. Seemed to make sense to me since I could get an ODBC conn via MS Acces and that Ora driver, as well as TNSPING it from the machine in question making the call. I'm likely going off topic greatly with this, so forgive me if that's the case, but if anyone can affirm this, that's also very helpful. Thanks, folks!

I had that happen periodically for years with my version of TC 4.1.31. With some folks, we could get it to go away, by cleaning out browser cache. With others, it was the same people that incurred it all the time. They could access other protected areas, but not the one. I ended up making a duplicate non-protected piece for them. For me it wasn't a big deal, because they already were -- in a sense -- in a protected piece to begin with.
