HI, Guys:
I have a question about this error:
ERROR 2009-03-27 13:34:27,671 [RecoverThread for backend DBB]
controller.recoverylog.RecoverThread.error - Recovery process failed to
replay: request Autocommit StatementExecuteUpdateTask 281474976710657
(INSERT INTO tb_test (col_id, col_remark4, col_type) VALUES (?, ?,
?)/<!%S|003|!%><!%S|I am string|!%><!%I|100|!%>) (Backend VDB -
BackendWorkerThread for backend 'configDBB57' with RAIDb level:1 failed
(null))
After that I have added some log in the code, below is the error
message after I added the log.
21:29:38,351 DEBUG group.bottom.GroupBottomSession Sending message

ndWorkerThread.java:197)
Finally I found out the reason is "backendRequestInterceptors" is
null.
"backendRequestInterceptors" is configured by
controller_default.properties
My question is what is the meaning about "backend.interceptors" how
to configure it.
I really appreciate for your help.
Thanks
Alex
