Hi:
I want to write a program which will do the same work as we do a
clear qlocal(<queuename>) command from runmqsc command. I want to accomplish the same using MqSeries C++ API call. Pls. help.
Best regards

You want to create a PCF message that clears the queue.
Or use the MQAI API to clear the queue.
See the Programmable System Management manual or the Administrative Interface Programming Guide manual for more information. Both are available here http://www-3.ibm.com/software/ts/mqseries/library/manualsa/. |

The other possibility is to use the system command or something similar to actually execute runmqsc from your C program, and directly issuing the clear ql command. I've done this with Perl, and it works very well. Using open2, you can even use input and output buffers to interact with runmqsc and issue subsequent commands based on the result of previous commands.

| See the sample program amqsailq.c under <MQ>\tools\c\samples. It uses MQAI to determine the current depth of a queue, but should be readily adaptable. |

hi:
I've tried the programe.. but it's giving the error:
Local queue clear test failed: Completion Code = 2 : Reason = 3008
Error returned by the command server: Completion Code = 2 : Reason = 3020
Pls. help.
follwing is the code snippet to clear the queue:
mqCreateBag(MQCBO_ADMIN_BAG, &responseBag, &compCode, &reason);
mqAddString(adminBag, MQCA_Q_NAME, MQBL_NULL_TERMINATED, "test", &compCode, &reason);
mqAddInteger(adminBag, MQIA_Q_TYPE, MQQT_LOCAL, &compCode, &reason);
mqExecute(hConn, MQCMD_CLEAR_Q, MQHB_NONE, adminBag, responseBag, MQHO_NONE, MQHO_NONE, &compCode, &reason);
regards

Use "mqrc" on the command line:
mqrc 3008
3008 0x00000bc0 MQRCCF_COMMAND_FAILED
mqrc 3020
3020 0x00000bcc MQRCCF_PARM_COUNT_TOO_BIG
Too many parameters (arguements)?
Looks like a case for "read the manual"! Although where the MQAI is documented I'm not 100% sure I'm afraid  |

| Clearing a queue doesn't require you to specify the queue type - it has to be local. Take out the mqAddInteger line. This is documented in the manual. |
