MQSeries.net :: View topic - MQ Message Grouping

plivo · Posted: Wed Oct 31, 2007 2:51 am Post subject:

Due to messages being received on the mainframe local queue being out of order, I am wanting to turn on message grouping so that MQ messages will be processed in order.

When getting a message off the queue, the MQGet Option needs to include MQMGO_LOGICAL_ORDER ( and MQGMO_ALL_MSGS_AVAILABLE).

When I add this to my PLI program, it does not compile because these named constants are not defined.

PLI uses the include file CMQP to define the structures and named constants for the main MQI. When I look into this file, the MQMGO does not include these constant definitions.

I can only gather that this is an old MQI version that does not understand about the MQ Message grouping function, however in this same dataset, there are options that one uses such as MQGS_LAST_MSG_IN_GROUP
that is defined.

Below is the MQI CMQP structures and name constants that is on my system.....

/* Structure Identifier */
%dcl MQGMO_STRUC_ID char;
%MQGMO_STRUC_ID = '''GMO ''';

/* Structure Version Number */
%dcl MQGMO_VERSION_1 char;
%dcl MQGMO_VERSION_2 char;
%dcl MQGMO_VERSION_3 char;
%dcl MQGMO_CURRENT_VERSION char;
%MQGMO_VERSION_1 = '1';
%MQGMO_VERSION_2 = '2';
%MQGMO_VERSION_3 = '3';
%MQGMO_CURRENT_VERSION = '3';

/* Get-Message Options */
%dcl MQGMO_WAIT char;
%dcl MQGMO_NO_WAIT char;
%dcl MQGMO_SYNCPOINT char;
%dcl MQGMO_SYNCPOINT_IF_PERSISTENT char;
%dcl MQGMO_NO_SYNCPOINT char;
%dcl MQGMO_MARK_SKIP_BACKOUT char;
%dcl MQGMO_BROWSE_FIRST char;
%dcl MQGMO_BROWSE_NEXT char;
%dcl MQGMO_MSG_UNDER_CURSOR char;
%dcl MQGMO_ACCEPT_TRUNCATED_MSG char;
%dcl MQGMO_SET_SIGNAL char;
%dcl MQGMO_FAIL_IF_QUIESCING char;
%dcl MQGMO_CONVERT char;
%dcl MQGMO_NONE char;
%MQGMO_WAIT = '1';
%MQGMO_NO_WAIT = '0';
%MQGMO_SYNCPOINT = '2';
%MQGMO_SYNCPOINT_IF_PERSISTENT = '4096';
%MQGMO_NO_SYNCPOINT = '4';
%MQGMO_MARK_SKIP_BACKOUT = '128';
%MQGMO_BROWSE_FIRST = '16';
%MQGMO_BROWSE_NEXT = '32';
%MQGMO_MSG_UNDER_CURSOR = '256';
%MQGMO_ACCEPT_TRUNCATED_MSG = '64';
%MQGMO_SET_SIGNAL = '8';
%MQGMO_FAIL_IF_QUIESCING = '8192';
%MQGMO_CONVERT = '16384';
%MQGMO_NONE = '0';

Any suggestions on what I need to do to verify versions, updates would be much appreciated.
