I have configured a sender and receiver channel on 2000.I have defined a new format and created the dll and copied it in MQSeries/Exits dir.Next I run my MQPUT with MQMD as my new format in the code.But the code end with
MQPUT ended with reason code 2026...
Can anyone say what is wrong. Else can any one give me a step by step instruction to write a channel exit on NT/2000.
Thanx,
Abhijit. |

| If you are getting a 2026 on the MQPUT, I don't think your channel exits have even come into play. I'd double-check your code to make sure that you didn't corrupt the MQMD while you were building it. If you don't spot anything, post the code fragment here. |

| I think format names beginning MQ* are reserved - probably better to name it something else. MQ may be getting in your way and trying to deal with it first. |

Here is the complete steps which I have tried
1)Created QM1 and QM2 where QM1 is running on Port 1411 and QM2 running on 1412.I have created a remote Q def + a transmission Q and a sender channel with data convert Yes in QM1 and a corresponding receiver channel and local Q in QM2.
2)I have created a format
typedef struct _mymsg {
MQCHAR ID;
} mymsg; and I name it as MYFORMAT and created a dll.I have also defined the entry point in the MYFORMAT.DEF and placed the dll and .def file in the MQSERIES/Exits directory
3)I tried to run the following code --
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <cmqc.h>
#define BLANKS ''
#define MQFMT_TEST "MYFORMAT"
int main(int argc, char **argv)
{
FILE *fp;
int i;
MQOD od = {MQOD_DEFAULT}; /* Object Descriptor */
MQOD odr = {MQOD_DEFAULT}; /* Object Descriptor for reply */
//MQMD md = {MQMD_DEFAULT}; /* Message Descriptor */
MQMD md ; /* Message Descriptor */
MQPMO pmo = {MQPMO_DEFAULT}; /* put message options */
MQHCONN Hcon; /* connection handle */
MQHOBJ Hobj; /* object handle (server) */
MQHOBJ Hreply; /* object handle for reply */

char QMName[50], QName[50]; /* queue manager name

//int replyct;
printf("MQPUT start...\n");
if (argc < 1)
{
printf("Required parameter missing - queue name\n");
exit(99);
}
//printf("Argc is %d\n", argc);
strcpy(QName, argv[1]);
QMName[0] = 0; /* default */
if (argc > 2)
strcpy(QMName, argv[2]);
//1.

if (CompCode == MQCC_FAILED)

exit(CReason);
}
strncpy(od.ObjectName, argv[1], MQ_Q_NAME_LENGTH);
O_options = MQOO_OUTPUT /* open queue for output */
+ MQOO_FAIL_IF_QUIESCING; /* but not if MQM stopping */
//2.
MQOPEN(Hcon, /* connection handle */

printf("MQOPEN ended with reason code %ld\n", Reason);
}
if (OpenCode == MQCC_FAILED)
{
printf("unable to open server queue for output %ld \n", Reason);
i= Reason;
MQDISC(&Hcon, /* connection handle */
&CompCode, /* completion code */
&Reason);
exit(i);
}
O_options = MQOO_INPUT_EXCLUSIVE
+ MQOO_FAIL_IF_QUIESCING;
CompCode = OpenCode; /* use MQOPEN result for initial test */
fp = stdin;
fgets(buffer, sizeof(buffer) - 1, fp) ;
buflen = strlen(buffer) - 1;
buffer[buflen] = '\0';

Could the problem be that you are not populating the md with default values?
| Code: |
//MQMD md = {MQMD_DEFAULT}; /* Message Descriptor */
MQMD md ; /* Message Descriptor */ |
| Quote: |
MQRC_MD_ERROR (2026, X'07EA')
Explanation: The MQMD structure is not valid, for one of the following reasons:
The StrucId field is not MQMD_STRUC_ID.
The Version field specifies a value that is not valid or not supported.
The parameter pointer is not valid. (It is not always possible to detect parameter pointers that are not valid; if not detected, unpredictable results occur.)
The queue manager cannot copy the changed structure to application storage, even though the call is successful. This can occur, for example, if the pointer points to read-only storage. |
