jta Atomikos 启动报错

?

09-10-15 17:42:34,781 [main] Error in recovery?
javax.transaction.xa.XAException?.......

启动时jta报错的问题已经解决，oracle用户要拥有以下权限?
grant select on sys.dba_pending_transactions to <user name>;?
grant select on sys.pending_trans$ to <user name>;?
grant select on sys.dba_2pc_pending to <user name>;?
grant execute on sys.dbms_system to <user name>;?
但是，事务仍然不起作用?
