[JBoss Messaging] - Maximum message size?

by Nikos Massios

Nikos Massios [http://community.jboss.org/people/massios] created the discussion "Maximum message size?" To view the discussion, visit: http://community.jboss.org/message/569784#569784 -------------------------------------------------------------- Hello, We are using, JBoss 5.1 GA JBoss Messaging 1.4.3GA Oracle 10.2.0.1 We have noticed the following problem If we put a message in the queue that is very large for example larger than a few megabytes the messaging system becomes very slow. We have noticed that the schema created in the database for JBoss Messaging in oracle does not have enough indexes or foreign keys on the tables. Questions a) Has anyone improved the schema create script for oracle? b) Has anyone tried messages of similar size with success? Thanks in advance, Nikos. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/569784#569784] Start a new discussion in JBoss Messaging at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JBoss Messaging] - Re: JBM stops reconnection to a remote provider

by Yong Hao Gao

Yong Hao Gao [http://community.jboss.org/people/gaohoward] created the discussion "Re: JBM stops reconnection to a remote provider" To view the discussion, visit: http://community.jboss.org/message/569857#569857 -------------------------------------------------------------- I think it is one of MDB configurations "reconnectAttempts". However this is not part of JBM, you need to verify yourself or go to JBoss JCA forum for more help. By the way, JBM is in maintenance mode only, meaning there won't be regular community release, only EAP releases. I'd suggest you consider HornetQ. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/569857#569857] Start a new discussion in JBoss Messaging at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

The above link points to the documentation for AS 5.x. Does that mean that there is no changes for AS 6.x as far as MDB handling? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/569841#569841] Start a new discussion in EJB3 at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JBoss Messaging] - JBM stops reconnection to a remote provider

When I stop the JMS Provider the other instance starts reconnection procedure. If the JMS propvider is re-started quickly the reconnection goes fine but if the provider stays down a few minute no reconnection occurs. In fact the client instance stops reconnection procedure after a few tries. Does anyone knows how to configure this behaviour ? thanks ivan Hi I have two JBoss 5.1.0 instances running JBM 1.4.3, one is JMS provider, on the other I have a MDB client.

But the later spec compliant versions (like AS 5.x and AS 6.x) won't even allow you to cast the JNDI proxy to BarService, since that's not exposed as a business interface. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/569834#569834] Start a new discussion in EJB3 at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JNDI and Naming] - Programmatically determining JNDI context / ear name in JBoss 5.1

I just can't find what is it is now. Can someone point it out to me please?

[JNDI and Naming] - JBoss 4.0.2 -> 5.1 problem with EJB3 lookup via jndi

by BalaÃ¿ ClÃ©ment

BalaÃ¿ ClÃ©ment [http://community.jboss.org/people/skin123] created the discussion "JBoss 4.0.2 -> 5.1 problem with EJB3 lookup via jndi" To view the discussion, visit: http://community.jboss.org/message/569674#569674 -------------------------------------------------------------- Hello, my problem is verry simple but i dont know if a solution exists. The global JNDI name has changed between jboss 4.0.2 and 5.1. By exemple I have one EJB named *PostManagerBean* with interface *PostManager* @Stateless @Local(PostManager.class) public class PostManagerBean implements PostManager { ... } public interface PostManager { ... } To load this EJB with JBoss 4.0.2 i use: *context.lookup("com.post.PostManager")* with Jboss 5.1, I need to use *context.lookup("PostManagerBean/local")* Is it possible to configure JBoss 5.1 to set the format of EJB3 jndi name inscription ? i.e I'd like to load EJB3 in JBoss 5.1 with: *context.lookup("com.post.PostManager")* without annotation changement in my bean (with annotation @LocalBinding). Thank you very much for responses -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/569674#569674] Start a new discussion in JNDI and Naming at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JBoss Remoting] - sslservlet transport - too many client requests

by Janardhan Burugupalli

Janardhan Burugupalli [http://community.jboss.org/people/jburugupalli] created the discussion "sslservlet transport - too many client requests" To view the discussion, visit: http://community.jboss.org/message/569811#569811 -------------------------------------------------------------- HI All, I am using remoting 2.5.1 with JBoss 5.1.0 I have setup sslservlet transport for my EJB2 beans. The invocation from the client side works fine. Invocation URL https://serverName:443/unified-invoker/SSLJNDIFactory/?dataType=invocatio... https://serverName:443/unified-invoker/SSLJNDIFactory/?dataType=invocatio... To measure performance with a server behind firewall, I made a call on the server which returns a big List with objects back to the client. Too many server client pings with small data (maximum of 1434 bytes). I monitored this single call with wireShark and the data is as follows || *Nr* || *Time(milli seconds)* || | 1 - 60 (just for logging in) | 4.54 | | *After this method call to fetch huge data* | | | 61 (response from the huge method) | 123.47 (response after a delay of 120 seconds, I checked the server and the mthod took 93 seconds) | | *3881* (somany exchanges from server) | 215.574 | So the initial calls 1-60 are just remoting calls for the authentication. After that the actual method is called. After a huge delay the first response from the server us obtained. After the first response there are 3800 more exchanges between the server and the client to complete the data transfer. I tried to use the -Dremoting.payload.size=4098 as a VM param to increase the packet size and decrease the client/server traffic, but did not work. Is there a way to over come this problem? Appreciate any feedback. thanks. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/569811#569811] Start a new discussion in JBoss Remoting at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
