Error description
A channel sending messages in syncpoint does not correctly close the batch when BATCHLIM bytes have been transmitted.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Channel batch not committed after * * BATCHLIM bytes have been transferred. * **************************************************************** * RECOMMENDATION: * **************************************************************** When messages are sent across a channel, and the number of bytes transmitted in the current batch exceeds the channel's BATCHLIM setting the batch should be closed, causing a confirm request to be sent to the remote channel, and any uncommitted messages to be committed. However, if the channel is using a large (>32K) transmission buffer (for example, when sending large messages) this does not occur correctly, and the batch is not closed until BATCHSZ messages have been sent or the transmission queue has been empty for more than BATCHINT seconds.
Problem conclusion
rriSendData is changed to correctly update the count of bytes in the current batch when using a large transmission buffer, so that the batch is correctly closed if the transmission of a message causes the number of bytes sent to exceed BATCHLIM. 100Y CSQXRMTR
