I'm attempting to get the channel type from my MQ virtual appliance. I have a java app and everything seems to be working fine except this.
String[] chTypeText = {"SENDER", "SERVER", "RECEIVER", "REQUESTER", "SVRCONN", "CLNTCONN", "CLUSRCVR", "CLUSSDIR"};
The channel type I'm inquiring about is definitely a SVRCONN channel because that's how it's listed in "display channel(*)". However the chTypeText keeps indexing to "CLUSSDIR" or int = 7 as the results.
Are my constants in chTypeText in the correct order? Am I missing any?
Thanks..any guidance is much appreciated. |

Should not "CLUSSDIR" read "CLUSSDR" ?

Apologies...yes it should have been
String[] chTypeText = {"SENDER", "SERVER", "RECEIVER", "REQUESTER", "SVRCONN", "CLNTCONN", "CLUSRCVR", "CLUSSDR"};
That has been corrected. But the index being returned is "7" which would indicate that the channel type is a "CLUSSDR" but it's a SVRCONN channel.
So I'm asking if the constants are correct and in the appropriate position and / or am I missing any because the returned value is not correct with respect to the actual channel type.
Thanks xerk |

Hi,
I think you are confused about the channel type value returned:
| Code: |
- MQCHT_SENDER = 1
- MQCHT_SERVER = 2
- MQCHT_RECEIVER = 3
- MQCHT_REQUESTER = 4
- MQCHT_ALL" = 5
- MQCHT_CLNTCONN = 6
- MQCHT_SVRCONN = 7
- MQCHT_CLUSRCVR = 8
- MQCHT_CLUSSDR = 9
- MQCHT_MQTT = 10
- MQCHT_AMQP = 11 |
So, technically speaking, assuming zero-based, your string array should be:
| Code: |
| String[] chTypeText = {"", "SENDER", "SERVER", "RECEIVER", "REQUESTER", "ALL", "CLNTCONN", "SVRCONN", "CLUSRCVR", "CLUSSDR", "MQTT", "AMQP"}; |

| To avoid the hardcoded text in your program, I'd use something like MQConstants.lookup(value, "MQCHT_.*"). |

| Thanks Roger. Appreciate the advice. I'm new to PCF and the example I found for those values was what I posted. Your update is spot on. A bit difficult to find to PCF examples. I like the examples on Capitalware. |

In MQ v8 there is a new C/C++ header file cmqstrc.h that has functions for mapping integer values to constant strings. The MQCHT_STR function returns "MQCHT_SVRCONN" for value 7.
