Hi All,
I have a problem w MQ.
What i m trying to do is pretty simple.
1. Browse the Message
2. if ( my message found )
delete the message
3. browse next message
I m using C and MQ v5.3 CSD 12.
Following are my options for the above logic
do
{
browsegmo.Version = MQGMO_VERSION_2;
browsegmo.Options = MQGMO_NO_WAIT + MQGMO_BROWSE_NEXT;
browsegmo.MatchOptions = MQMO_NONE;
memcpy(pgmoin, &browsegmo, sizeof(MQGMO) );
printf("\n %d Messages found for queue '%s'",QDepth,Qname);
memcpy(md.MsgId, MQMI_NONE, sizeof(md.MsgId));
memcpy(md.CorrelId, MQCI_NONE, sizeof(md.CorrelId));
md.Version = MQMD_VERSION_2 ;
memcpy(pmdin, &md, sizeof(MQMD) );
memset(buffer,'\0',buflen);
MQGET(HCon, /* connection handle */
Herrorq, /* object handle */
pmdin, /* message descriptor */
pgmoin, /* get message options */
buflen, /* buffer length */
buffer, /* message buffer */
&messlen, /* message length */
&CompCode, /* completion code */
&QReason); /* reason code */
if ( /* my message found */)
{
memset(pgmoin,'\0',sizeof(MQGMO));
browsegmo.Version = MQGMO_VERSION_2;
browsegmo.Options = MQGMO_NO_WAIT + MQGMO_BROWSE_MSG_UNDER_CURSOR ;
browsegmo.MatchOptions = MQMO_NONE;
memcpy(pgmoin, &browsegmo, sizeof(MQGMO) );
MQGET(...................)
}
i Know lots of ppl hv asked this question.
But i need some help w above code..
It doesnt do as expected..it simply browses the message , and when the required message is found..it doesnt delete it , even after specifying
MQGMO_BROWSE_MSG_UNDER_CURSOR option.
Can someone tell me what/where am i going wrong?.
Thanks a ton.
I m losing my hair..over this..

You know, reading the App Prog Ref manual does help. As does using MQGMO_MSG_UNDER_CURSOR
BROWSE means BROWSE!
| Quote: |
MQGMO_BROWSE_MSG_UNDER_CURSOR
Browse message under browse cursor.
This option causes the message pointed to by the browse cursor to be
retrieved nondestructively, regardless of the MQMO_* options specified in
the MatchOptions field in MQGMO. |

ok. Thanx for that.
But how do i delete the messages now..
Do i have to re-open the queue in non-browse mode.
i m sure this is not the way..
i wrote the code based on the the sample provided by IBM..

The append you responded to is 9 months old. It might be quicker to look at the samples and read the manual. |
