by jboss＠biancashouse.com

I tried to get postgres and Portal playing ball, but I think it's a similar issue to the Oracle one - lousy jdbc implementations. If you have Oracle, why not try using that again - see my script (blue) for getting it all going together... http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4003786#4003786 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4004110#4004110 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4004110

[EJB 3.0] - How to speed up your remote EJB calls

by javajedi

I've been doing some profiling of our remote EJB3 invocations, and I just wanted to post and share what I found out. I was able to achieve an average 50% performance boost for our remote calls by changing 1 line in deploy/ejb3.deployer/META-INF/jboss-service.xml: Original line:<attribute name="InvokerLocator">socket://${jboss.bind.address}:3873</attribute> New line:<attribute name="InvokerLocator">socket://${jboss.bind.address}:3873/?serializationtype=jboss&socket.check_connection=false</attribute> JBoss serialization gives a really nice performance boost. However, I did run into a bug in JBoss AOP when I enabled it. I posted a patch for this at http://jira.jboss.com/jira/browse/JBAOP-347. The other change that gave an almost equally impressive boost was the check_connection=false bit. The socket transport sends a 1 byte ping to the server and waits for a 1 byte response before handing the socket back to the client from the pool. So because of this, every remote invocation actually involves 2 round trips by default. Adding this parameter to disable this check shaves a few milliseconds off of each remote call, on average. However, this does seem to cause a problem in that, once the socket connection times out (default configuration value is 1 minute), the subsequent remote call fails on the client side, because it tries to reuse the closed socket connection. The call after this is fine because it gets a fresh connection. So to resolve this, I increased the socket connection timeout to 10 minutes (timeout=600000), and created a custom client-side interceptor that wraps the invocation, checks for an IOException, and retries the call once when it happens. This seems to be working pretty well, and is significantly faster. If anyone has any suggestions for how to squeeze some more performance out of the transport, or sees anything potentially wrong with what I'm doing, I'd appreciate hearing about it. :) --Tim View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4004109#4004109 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4004109

[JBoss Portal] - Re: jboss-portal-2.6-ALPHA1-bundled with Oracle

by jboss＠biancashouse.com

This is a work in progress, but the following is a checklist of things that make Portal work with Oracle. Hope it is helpful to you... Ian Installed using jem installer 1.2.GA Datasource is Oracle thin driver, with username jbportal241 Portal-2.6-alpha1 Changes made to get Portal working with Oracle ============================================== Using oci rather than thin driver --------------------------------- It is recommeded we use the oci style of connection. The latest oci drivers can be downloaded from Oracle. You have to unzip the download into a directory and add that directory to the windows path. You also have to copy the ojdbc.jar to the lib directoy for your deployment directory. If you already had an Oracle client, you'll need to rename a property in your windows registry: \HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\NLS_LANG Use a later version of Apache JackRabbit ---------------------------------------- In portal-cms.sar, replace jackrabbit-core-1.0.jar with jackrabbit-core-1.1.1.jar Edited portal-cms.sar/META-INF/jboss-service.xml to make use of OracleFileSystem that is now available in the newer jackrabbit API. Note - the oracle username and password are found in the new file. Moved portal-cms.war into portal-cms.sar Workarounds for bugs in Oracle's JDBC driver -------------------------------------------- See http://forum.hibernate.org/viewtopic.php?t=82 and http://forum.hibernate.org/viewtopic.php?t=930650 and http://jira.jboss.com/jira/browse/JBAS-191 Gavin King reminds us that Oracle don't handle out-join-fetching properly, and recommends we disable it. So I found how to do this in the Hibernate reference docs: http://www.hibernate.org/hib_docs/reference/en/html/session-configuration... 3.4.2. Outer Join Fetching -------------------------- If your database supports ANSI, Oracle or Sybase style outer joins, outer join fetching will often increase performance by limiting the number of round trips to and from the database (at the cost of possibly more work performed by the database itself). Outer join fetching allows a whole graph of objects connected by many-to-one, one-to-many, many-to-many and one-to-one associations to be retrieved in a single SQL SELECT. Gavin King informs us that Oracle doesn't handle out-join-fetching properly, and recommends we disable it. So I found how to do this in the Hibernate reference docs: http://www.hibernate.org/hib_docs/reference/en/html/session-configuration... Outer join fetching may be disabled globally by setting the property hibernate.max_fetch_depth to 0. A setting of 1 or higher enables outer join fetching for one-to-one and many-to-one associations which have been mapped with fetch="join". See Section 19.1, ?Fetching strategies? for more information. So I add the following lines: org.hibernate.dialect.Oracle9Dialect 0 to hibernate.cfg.xml in these directories: jboss-portal.sar/conf/hibernate/instance jboss-portal.sar/conf/hibernate/portal jboss-portal.sar/conf/hibernate/portlet jboss-portal.sar/conf/hibernate/user jboss-portal.sar/portal-cms.sar/conf/hibernate/cms Bug in SQL generation from Hibernate mappings ============================================= Table JBP_OBJECT_NODE does not get generated due to the following SQl being generated: create table JBP_OBJECT_NODE ( PK number(19,0) not null, PATH varchar2(255 char) unique, NAME varchar2(255 char), PARENT_KEY number(19,0), primary key (PK), unique (PATH) ) remove unique="true" from the PATH column mapping in jboss-portal.sar/conf/hibernate/portal/domain.hbm.xml This bug also applies to the mapping for JBP_INSTANCE, so remove the same entry from: jboss-portal.sar/conf/hibernate/instance/domain.hbm.xml Oracle CLOB mapping problem =========================== Refer to the JIRA: http://jira.jboss.com/jira/browse/JBAS-191 ... please ensure that you are using the absolute latest Oracle 9.2 JDBC drivers, even if your database is Oracle 8. Also, you must use the "OCI" variant if you want to store LOB's greater than about 4k... Refer to Oracle's description of the CLOBS: http://www.oracle.com/technology/sample_code/tech/java/codesnippet/jdbc/c... I have download the latest oracle 10g R2 jdbc driver 10.2.0.2 Workaround for Oracle version of JBoss Forums --------------------------------------------- apply the same as above to hibernate.cfg.xml in jboss-forums.ear/portal-forums.sar/conf Jboss Forums ear has a bug - missing Faces listener =================================================== Add the following listener to jboss-forums.ear/portal-forums.war/WEB-INF/web.xml  <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class> Changed the deployment xml so that ForumsPortlet not deployed - just JSFForumsPortlet NOTE - Forums won't work with Portal Alpha1 - class cast exception - waiting for someone to identify that problem - use Portal 2.6DR is you need Forums View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4004097#4004097 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4004097

[Beginners Corner] - Re: could anybody tell me the exact structure of SAR.

by genman

log4j.xml exists in $JBOSS_HOME/server/default/conf . As for the jars, if they are for the .war only, they go in there.

[Remoting] - Re: Has anyone actually tried using the CompressingMarshalle

by ron.sigal＠jboss.com

Hi Mister Jedi (or is it Master Jedi?) (or can I just call you "java"?), Well, I wrote the CompressingMarshaller, so I better look into it. Do you happen to have a test case closer to the metal (i.e., just using Remoting)?

[Messaging, JMS & JBossMQ] - Re: Hypersonic localDB.data file size limit

by genman

jeffdo - Really a HSQL and not JBossMQ question, but you can run that statement as SQL command and it sets it within the file. Create a fix.bsh script that accesses the DataSource and runs the SQL command. http://wiki.jboss.org/wiki/Wiki.jsp?page=BSHDeployer View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4004088#4004088 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4004088

Also, using pure JMS, you could "add" this message to another queue when consuming from the original queue.

[Messaging, JMS & JBossMQ] - Re: How to store JMS messages permanently in the database

by genman

Meaning, you don't want the messages deleted upon acknowledgement? It might be easiest with Oracle to simply have a trigger upon delete that copies the data to a second table. You can theoretically alter the persistence manager, since the class is pluggable to do the same.
