[Clustering/JBoss] - Re: ConcurrentModificationException during session serializa

by smarlow＠redhat.com

Currently, deployed applications do not hold a RL lock while processing requests. If we introduce a RL lock to be held while processing requests, will that be slower? There is some potential additional overhead to the ReadWriteLock (http://java.sun.com/j2se/1.5.0/docs/api/java/util/concurrent/locks/ReadWr...). Perhaps it would be better (performance wise) to synchronize on the session level facade object as I think the performance should be close to what applications currently see (whether or not they also synchronize on the session object when accessing mutable attributes). What do you think?

[JBoss Cache: Core Edition] - Re: JDBCCacheLoader with Oracle 10g problem

by niuxuetao_fiserv

And the error log from JDBCCacheLoader right after this debug log is this: | [2009-07-01 16:11:48,367] [Detection1] ERROR JDBCCacheLoader - Failed to insert node :ORA-01461: can bind a LONG value only for insert into a LONG column | And the error stack trace is the same as I posted on the top floor of this thread.

This is a MySQL error message. Increase the max_allowed_packet variable in the your MySQL config file (my.ini on Windows) and restart MySQL.

No, sorry, I managed to reproduce the problem with one thread on DEBUG level. Here is the log: | [2009-07-01 16:11:48,367] [Detection1] DEBUG JDBCCacheLoader - executing sql: INSERT INTO Cached_Events (fqn, node, parent) SELECT ?, ?, ? FROM Cached_Events_D WHERE NOT EXISTS (SELECT fqn FROM Cached_Events WHERE fqn = ?) (/__JBossInternal__/RTDE/pattern-matching-threshold/663330655/_ID_/aaaa-uiq8an-fwm4m5h3-1-fwm4m8s0-z) | Still don't know how to fill in the question marks to run it...

Btw, I was testing with 5 threads when seeing the DEBUG logs above. I also tested with 1 thread, bug with DEBUG level on "org.jboss", I cannot recreate any exceptions. However, with WARN debug level for "org.jboss" I still can reproduce it as described on my original post. Weird...

[JBoss Cache: Core Edition] - Re: JDBCCacheLoader with Oracle 10g problem

by niuxuetao_fiserv

Hi Mircea, Thanks for the hints, I looked at the debug log, the sql statement being logged right before the exception is not a "INSERT INTO, but a select": | | DEBUG JDBCCacheLoader - executing sql: select fqn from Cached_Events where parent=? (/) | | I tries to execute the statement: select fqn from Cached_Events where parent='/', it finds something in the table. The 1st insert into statement is logged far after the exception is logged. This is the log msg for it, and it is surprisingly involving the automatically created table 'cached_events_d': | DEBUG JDBCCacheLoader - executing sql: INSERT INTO Cached_Events (fqn, node, parent) SELECT ?, ?, ? FROM Cached_Events_D WHERE NOT EXISTS (SELECT fqn FROM Cached_Events WHERE fqn = ?) (/RTDE/time-distance-analysis-gps/0) | I don't know how to execute this in the console (Oracle SQL Developer) Any idea?

[JBoss jBPM] - Re: running jBMP on Weblogic Server 10.x

by smart_umesh_123

Hi, Thanks for the valuable suggestions given by all of you till now. I have one more query to ask you. At present application is using TeamWorks BPM tool. Due to some business reason they want to change to other BPM tool. so we are evaluating jBPM and Intalio BPM. I am posting one example of TeamWorks BPD. I want your input about how easily we can develop such type of BPD using jBPM. Process Definition: Meeting Reconciliation There will be two swimlanes namely Meeting Organizer and System(TeamWorks Process) 1) After meeting has successfully taken place/occurred, control comes to Meeting Reconciliation 2) System sends reminder mails stating meeting is pending for re-conciliation. (in this case TeamWorks has email address stored in it's DB) 3) Meeting Requestor will check his mail and complete his re-conciliation task. If Requestor ignore the email then after 15/30 days process # 2 will be executed again. 4) even if Requestor has not completed re-conciliation within 35 days, System will close the meeting. I am sorry for not pasting Process Diagram because i couldn't able to insert image. One more point to add here is, actual application have business process which calls other process and web service. Let me know if you need more information.
