Hi
Can anyone explain the concept around "fastbound application", how to identify and change a fastbound app.
Any help is greatly appreciated.
Regards

Do you mean "fastpath binding". If so, that is controlled by the application doing the conection, not at the MQ level. So, to change it, you would have to change the application itself.
I'm not sure if there's a way to recognise if an application is using "fastpath".
Basically, it means that that the application runs as "part" of MQ, instead of as a seperate process. As usual, the manuals are your friend. Try reading them sometime. 
| Quote: |
| Trusted applications imply that the WebSphere MQ application and the local queue manager agent become the same process. Because the agent process no longer needs to use an interface to access the queue manager, these applications become an extension of the queue manager. |
The same manuals contain the following warning about FastPath:
| Quote: |
| This option compromises the integrity of the queue manager: there is no protection from overwriting its storage. This also applies if the application contains errors that can be exposed to messages and other data in the queue manager too. Consider these issues before using this option. |
Cheers,

| On a less formal note, I personally do not recommend using fastpath at all - the slightly better performance is not worth the risk, and one rarely finds himself in a state where mq doesn't run fast enough for current needs (after using the usual means to enhance performance, of course) |

I'd second hopsala's suggestion. Unless you have a dire need, a extremely well tested program, and no other recourse, don't use fastpath. IMHO, it should only be used with MQ family products, like channels and the broker.
V6 allows you to see who's connected via fastpath:
| Code: |
dis conn(*) type(*)
4 : dis conn(*) type(*)
AMQ8276: Display Connection details.
CONN(E51C394301010020)
EXTCONN(414D5143544553542020202020202020)
TYPE(*)
PID(19216) TID(1)
APPLTAG(amqzfuma) APPLTYPE(SYSTEM)
CHANNEL( ) CONNAME( )
CONNOPTS(MQCNO_FASTPATH_BINDING) USERID(wschutz)
UOWLOG( ) UOWSTDA( )
UOWSTTI( ) UOWLOGDA( )
UOWLOGTI( ) URTYPE(QMGR)
EXTURID(XA_FORMATID[00000000] XA_GTRID[] XA_BQUAL[])
QMURID(0.0) UOWSTATE(NONE)

Hi
Is there any way of identifying apps connected as fastpath in v 5.3.09?
