关于WMQ二阶段提交的问题?
看到如下一个题,答案是B,我想请教高手指点下,在qm.ini文件中具体是怎么设.
An AIX application is being developed that will use WebSphere MQ as the transaction manager
for a two-phase commit with a DB2 database and a WebSphere MQ queue. Where will changes
need to be made, if any, so that WebSphere MQ can manage the DB2 resource?
A.The tp_mon_name parameter in the DB2 configuration
B.The qm.ini configuration file
C.The mqs.ini configuration file
D.No changes need to be made. Both DB2 and WebSphere MQ are already XA compliant
Correct:B

1.如果是自己写程序实现MQ跟DB2之间的XA问题，不用修改；
2.如果是MB操作MQ跟DB2实现XA，则需要修改 qm.ini :
XAResourceManager:
Name=DB2
SwitchFile=db2swit
XAOpenString=db=MyDataSource,uid=MyUserId,pwd=MyPassword,toc=t
XACloseString=
ThreadOfControl=THREAD
并使用mqsisetdbparms修改Broker的配置 收起
