while testing the sample program AMQSAICQ.C that was supplied from IBM, I compiled the code, built the pgm file, but when running it i get a reason code of 2018---MQRC_HCONN_ERROR The connection handle Hconn is not valid. I dont get it, my libararies and everything are set...anybody run into this???? the as400 is on 5.1 thanks-- oh one note, I did change the code so it wouldnt take any params like the original but that's it....it ran fine on my win2000 machine...heres the code

i threw a statement in the code to let me know what the hConn value is and it is 0 everytime.....(as400)
but, when i ran it on my win2k box, that runs it fine it rturned a value of 8107680....

On OS/390, CICS applications and on AS/400, applications running in compatibility mode the MQCONN call always returns MQHC_DEF_HCONN (which is 0 as far as my knowledge goes). So you don't have to worry about that. Also you don't have to have the MQCONN call in your pplication. It should connect automatically. Remove MQCONN call and try your app and see if it works.
Another try is to purge or do an ENDJOB against all the jobs, if any, that you have submitted to run this app previously.

| thanks for the rare reply, however Im not sure what you meant..I know being on the as400 you need not specify the Qmgr but no MCONN? how will it know what variable to use to hold the connection handle i.e. hConn? I did remove the line to no avail. thanks again |

| okay...i went ahead and wrote another simple app that just puts a msg on a queue and the connection handle is also 0, so I guess it is valid having a vlaue of 0...back to the drawing board. |

| quite possibly going to seek support from IBM, we cannot get any pcf working and it appears it could be an setup/authority issue, does anyone know anything about such. thank you. |
